Метаболизм  сообщества обрастаний.  Сообщение I. Динамика видового состава, биомассы, микрогетеротрофов и РОВ в среде с  сообществом  на разных стадиях его формирования
Provedor de dados: 13
Autores: Таможняя, В. А.; Горомосова, С. А.; Шапиро, А. 3.; Ковальчук, Ю. Л.; Шахматова, О. А.
Прослежена  динамика  видового  состава,  биомассы и  элементов  метаболизма в сообществе  обрастаний  на протяжении 20 мес первичной сукцессии. Сформировавшееся на стеклянных пластинах сообщество  с интервалом 30 сут экспонировали в непроточной морской воде в течение 2 и 20 ч, воспроизводя аэробные и гипоксийные условия естественной среды. После экспозиции определяли численность гетеротрофных бактерий, сопутствующих макрообрастанию, и содержание РОВ. Показано,  что на разных стадиях развития (их выделено 4) сообщество обрастаний способно и выделять и поглощать растворенную органику. Направленность этого процесса определяется  биологией доминирующего вида и физиологическим состоянием его популяции. Выделение РОВ сообществом  происходит  на   стадии...

Скорость и эффективность усвоения копепод сцифоидной медузой Aurelia aurita L.
Provedor de dados: 13
Autores: Аннинский, Б. Е.
Скорость и эффективность переваривания корма медузами A. aurita изменялась соответственно нагрузке на структуры пищеварения. Полное переваривание копепод Calanus helgolandicus заканчивалось в течение  7—24 ч и проходило быстрее (Q10=1,2—1,4) при высокой температуре.  Зоопланктон усваивался в экспериментах на 39—86%, но максимально  возможные значения близки к 90%. Интенсивность питания — наиболее  вероятная причина вариабельности полученных результатов, тогда как температура, размеры медуз и состав пищи оказывают несущественное влияние на эффективность пищеварения.

Состав поверхностного фитопланктона Севастопольской  бухты по  результатам люминесцентного  анализа
Provedor de dados: 13
Autores: Роухияйнен, М. И.
На  основании  люминесцентного  анализа  фитопланктона  Севастопольской, бухты установлены следующие показатели: автотрофный  фитопланктон в среднем за год составил 85% суммарной численности и  98% биомассы. Почти половина автотрофного фитопланктона — это живые клетки и около 30%  —  автолизирующие. Остальная численность и  биомасса  получена за счет створок. Бесхлорофильный фитопланктон составил меньшую долю. Относительное его количество возросло  во  второй половине года, достигая 68,6% суммарной численности и 64,2% биомассы. Количество живой биомассы растительного планктона за счет гетеротрофных форм в течение года по абсолютным значениям выравнивается.

Экспериментально исследовалась  зависимость между  рационом и длительностью питания сцифоидной медузы A. aurita.  Получено, что при длительности питания, превышающей сутки, его интенсивность поддерживается на постоянном уровне. Оптимальный  рацион  (С, кал∙экз.-1∙ч-1) A.  aurita  при 7,8°С может быть рассчитан по  уравнению  С=0,0352±0,0021 W0,889 и при 19,7°С,  являющейся экстремальной для черноморской популяции этого вида, по  уравнению С=0,1130±0,0125 W0,889 , где W — сырая масса тела животных (г). Спецификой питания медуз  в  естественных условиях Черного моря является напряженность в  полном  удовлетворении  их пищевых потребностей, более заметная зимой, чем летом. Таким образом, наиболее очевидная причина возрастания  запасов A. aurita в Черном море...

Динамика изменений  биохимического состава  отдельных органов мидии Mytilus galloprovincialis при интоксикации соляром
Provedor de dados: 13
Autores: Дивавин, И. А.; Копытов, Ю. П.
Исследована динамика изменений  содержания; углеводов, белков, липидов и их фракций в гепатопанкреасе, жабрах и гонадах мидий при острой углеводородной (соляровой) интоксикции.  Приводится  схема  исследования биохимических компонентов. Отмечено изменение белкового  и углеводного обменов в гонадах мидий. Обнаружена положительная  корреляция в гонадах между белковым и углеводным обменами. Показано,  что обмен липидов при интоксикации соляром в гепатопанкреасе и  гонадах сходен. Содержание каротиноидов во всех органах резко  возрастало к концу опыта (7 сут).  Биохимические  изменения  объясняются подавлением  защитных  механизмов детоксикации и  адаптации гидробионтов.

Роль  детрита  в  питании двустворчатого  моллюска  Mytilus  galloprovincialis Lam.
Provedor de dados: 13
Autores: Финенко, Г. А.
В эксперименте в  проточной системе определены скорость фильтрации и эффективность  усвоения  фитогенного детрита  разной степени зрелости черноморскими моллюсками М.galloprovincialis.  Обе величины постоянны у одноразмерных мидий, потребляющих  1—40-суточный детрит. Сравнение скоростей фильтрации детрита и одноклеточных водорослей выявило более интенсивное потребление водорослей мелкими животными (массой до 3 г), в то время как крупные моллюски (&gt;50 г) отфильтровывали с большей скоростью мертвое  органическое вещество. Эффективность усвоения детритных частиц — 57—80%  — не зависит от их возраста и близка к усвояемости водорослевой пищи.

Характеристика многолетних изменений бентоса в прибрежной зоне района Севастополя
Provedor de dados: 13
Autores: Киселева, М. И.
Рассмотрены изменения  в развитии бентоса,  связанные  с воздействием естественных и антропогенных факторов. Опреснение воды способствовало появлению молоди двустворчатого моллюска Lentidium mediterraneum. Существовавшее на полигоне  временное сообщество   Nana—Diogenes исчезло и началось формирование нового сообщества лентидиума. В результате антропогенного воздействия обнаружено увеличение органического загрязнения, приведшего к появлению  сероводорода в грунте на глубине 4—6 м, которое является показателем загрязнения исследуемого района и увеличения видового разнообразия и численности полихет семейства Spionidae и исчезновения некоторых видов моллюсков.

Autores: Эмеретли, И. В.
Определяли сезонную динамику АТФ-азной активности, содержания фосфора неорганического  (Фн) и белка в  митохондриях печени, красных и белых мышц трех видов черноморских  рыб (скорпены, смариды, ставриды) на протяжении  полного годового цикла.  Установлено, что  величины исследованных показателей значительно изменяются в течение года и зависят от типа ткани, вида рыб, периода  годового цикла. Показано, что соотношение АТФ-азной активности митохондрий красных и белых мышц рыб изменяется на протяжении года и зависит от естественной подвижности рыб. Чем выше естественная подвижность рыб, тем значительнее различия между красными и белыми мышцами по величине АТФ-азной активности, содержанию Фн и белка в  митохондриях.

Распределение  пигментов фитопланктона  в западной части тропической Атлантики
Provedor de dados: 13
Autores: Воронова, О. К.
Рассмотрена пространственно-временная изменчивость поля пигментов фитопланктона тропического энергоактивного полигона, расположенного напротив устья  р. Амазонки. В основу работы легли  материалы, собранные в 32-м рейсе нис «Академик Вернадский».  Содержание хлорофилла а в основной части поверхностного слоя полигона было ниже 0,1 мг/м3. В распресненных участках оно возрастало до 0,26 мг/м3, свидетельствуя о положительном влиянии стока реки на усиление первично-продукционных процессов. Повышенные концентрации хлорофилла в зоне термоклина были приурочены к  ядрам повышенных скоростей, зафиксированных  на  полигоне течений.

Autores: Белокопытин, Ю. С.
Изучали потребление кислорода (O2) у хамсы и продолжительность плавания в гидродинамическом респирометре при разных  скоростях.  Установлено, что хамса имеет индивидуальную реакцию на встречный поток воды. Около 5,0% рыб не реагирует на скорость течения  30—50 см∙с-1. Оптимальные миграционные  скорости  хамсы находятся в пределах 15—25 см∙с-1. Активный обмен при такой скорости в 2—2,5 раза превышает  основной. Минимальные затраты энергии на единицу пути (1км)  у рыб средних размерных групп (10—11 см)  происходят при скорости плавания около 30 см∙с-1.

Autores: Морякова, В. К.; Загородняя, Ю. А.
В работе излагаются результаты исследований микрозоопланктона,  выполненные на трех меридиональных (по 23° з. д.,  0° и  с северо-запада на юго-восток в Гвинейском заливе)  и трех широтных (по экватору, 3° и 13° ю.  ш.)  разрезах, которые  проводились в комплексе с гидрологическими исследованиями.  В целом район исследований характеризовался  средними величинами  численности  и  биомассы  микрозоопланктона. Более высокие величины отмечены в зонах  подъема вод  и  повышенных градиентов солености. Обнаруженная  неоднородность в распределении микрозоопланктона отражает сложную динамическую  структуру вод исследуемого региона.

Эколого-морфологические особенности некоторых  водоплавающих птиц  в связи с  полетом и плаванием
Provedor de dados: 13
Autores: Мордвинов, Ю. Е.
На основе морфологического материала по 16 видам водных птиц  (чайкам, пластинчатоклювым, поганкам, гагарам) дается  анализ количественных и качественных особенностей строения крыльев и формы тела в связи с полетом и плаванием. С увеличением экологической связи птиц с водной средой совершенствуются гидродинамические качества  формы тела (показатель),  ухудшаются  летные  свойства  (возрастает нагрузка на крылья), происходит постепенное уменьшение общей длины и  площади крыла за счет редукции дистальной части (первостепенных маховых, кисти), улучшается обтекание тела при плавании в толще воды.  Проксимальный отдел крыла (плечо и предплечье) относительно  увеличивается, что способствует сохранению летных качеств.

Autores: Драпун, И. Е.
Определены размеры и масса  особей  некоторых видов планктонных остракод и на их основе для 10 видов, а также семейства Halocyprididae рассчитаны параметры уравнения, связывающего массу тела (w) рачков с длиной (l) раковины: w = q·lb (1). Кроме того, исследовано влияние межвидовых различий в форме раковины на изменчивость параметров уравнения (1). Характеристикой формы   раковины послужило соотношение основных линейных размеров: длины (l)  и высоты (h). Рассчитаны уравнения, связывающие коэффициент q со средним для личинок и взрослых особей значением l/h и коэффициент b  с Δ(l/h) (показатель изменения пропорций раковины в онтогенезе). Полученные формулы позволяют рассчитать массу тела рачков любого вида остракод семейства Halocyprididae.

Представлены  материалы  наблюдений  за  скоростью  поглощения неорганических форм углерода и фосфора и их отношения, характеризующие фито- и бактериопланктон Севастопольской бухты. Исследования проведены с апреля 1985 по февраль 1986 г. с помощью радиоизотопных индикаторов 14С и 32Р во фракции микропланктона  0,45—150 мкм. Величины атомного отношения  скоростей поглощения  неорганических форм углерода и фосфора изменяются в  период исследований от 30:1 до 465:1. Значения между 30:1  и 60:1,  как наиболее часто встречающиеся, являются,  видимо, характерными для  фито- и  бактериопланктона  Севастопольской бухты в весенне-летний период и указывают  на  хорошую  обеспеченность вод  фосфатами.

Autores: Таможняя, В. А.; Горомосова, С. А.
Метаболизм двух сообществ микроорганизмов — перифитона и взвеси Севастопольской бухты Черного моря  изучали путем определения содержания в среде  аммония, нингидринположительных  веществ (НПВ) и углеводов после 2-часовой экспозиции этих сообществ в морской воде. Определения проводили  ежедекадно на протяжении 1983—1985 гг., используя сообщества разного  возраста (10, 20 и 30 сут).  Получено, что аммоний практически полностью утилизируется  перифитоном и взвесью,  углеводы — на  60—80%. Динамика НПВ в среде с сообществом отражает чередование процессов  выделения  и поглощения,  причем  в  30-суточном  сообществе доминирует экскреция НПВ. Метаболическая активность молодых (10 сут) сообществ перифитона и взвеси наиболее высока.  Потребление углеводов...

Изучались изменения структуры биоценоза  мидии, связанные с  флюктуациями численности и биомассы руководящего вида, под влиянием периодически повторяющихся в северо-западной части Черного моря заморов донной фауны.  Выяснено, что изменение количества мидий на  2—3 порядка может вызвать коренную перестройку ее биоценоза. Резкое сокращение численности и биомассы руководящего вида приводит к деградации биоценоза мидии вплоть до замены его другими сообществами, что и отмечалось в начале 80-х годов на Одесской банке.

Изучены  рост  и продукционные показатели двустворчатого моллюска Cerastoderma glaucum. Рост сердцевидок определяется  условиями обитания. При увеличении плотности поселения скорость  роста моллюсков снижается. Сравнение удельной продукции популяций из различных районов Черного и  Азовского морей свидетельствует, что более низкие значения  получены в биотопах, менее благоприятных  для роста и выживания старших возрастных классов. Максимальный вклад в суммарную биомассу дают младшие возрастные классы, которые даже при замедлении роста животных последующих возрастных групп увеличивают общую удельную популяцию. Суточная удельная продукция черноморских  сердцевидок колеблется в пределах 0,0008—0,0013 сут-1, азовских — 0,0011—0,0018 сут-1.

Autores: Роухияйнен, М. И.
Изучено распределение фитопланктона Атлантики.  Наибольшее его количество выявлено в районе возвышенности Сьерра-Леоне, где средняя  численность в слое 0—100 м составила  около 40 млн кл.·м-3, достигая в отдельных случаях (за счет Oscillatoria thiebautii)  130 млн кл. Достаточно высокая средняя (15 млн кл.) получена в зоне, прилегающей к Гвинейскому заливу, минимальная (3,2  млн кл.)  —  в Канарском течении. В пределах зон влияния различных течений количество фитопланктона существенно менялось. В пятнах повышенной концентрации фитопланктона численность превышала фоновую нередко на порядок.

Comportamento produtivo de ovinos Santa Inês no Estado do Acre.
Provedor de dados: 14
Autores: DIAS, R. P.; COSTA, A. L. da; MOREIRA, P.; VALENTIM, J. F.; SILVA, C. de S. e.
O rebanho ovino do Estado do Acre consiste, em sua grande maioria, de animais do tipo Sem Raça Definida (SRD), introduzidos pelos imigrantes provenientes das diversas regiões do Brasil. Esses animais apresentam grande quantidade de lã, sendo esta uma das principais características que dificultam a sua adaptação às condições de clima quente e úmido da região. Os sistemas de criação de ovinos no Acre apresentam baixo nível tecnológico, com pouco ou nenhum manejo, resultando na obtenção de baixos índices produtivos. A pouca disponibilidade de matrizes e reprodutores adaptados às condições climáticas da região, aliada a inexistência de um sistema de produção adequado, refletem na posição pouco destacada da ovinocultura na pecuária acreana. A tradição...

O NTIA tem se preocupado em experimentar alternativas para implementação de recursos para comunicação de dados que, de alguma maneira, viabilizem por parte das unidades descentralizadas, a colocação de informações de competência do centro de pesquisa disponíveis para acesso público. A RENPAC tem demonstrado ser um meio viável para colocação de bases de dados disponíveis a um grande número de usuários. Várias instituições já vem usando com sucesso, entre elas podemos citar o IBICT e o IBGE (veia anexo 1 - Bases de Dados disponíveis). A seguir faremos uma descrição das alternativas de uso da rede e como as unidades poderiam fazer uso da RENPAC. Veia o anexo III para uma noção de custos e alternativas de uso de cada modelo de acesso.

Melhoramento de populações de milho para o Acre.
Provedor de dados: 14
Autores: FARIAS NETO, J. T. de; CAMPOS, I. S.
A área cultivada com a cultura do milho no Estado do Acre vem se expandindo. Entretanto, a produtividade média está em torno de 1.280 kg/ha, mantendo-se constante nos 1timos anos. Este baixo índice de produtividade está associado, em grande parte, à utilização de cultivares de origem genética desconhecida que apresentam características inadequadas para a região, tais como: porte alto, mal empalhamento, susceptibilidade pragas e doenças e baixo potencial produtivo. A substituição dessas cultivares por outras mais produtivas e adaptadas s condições locais, constitui-se numa tecnologia simples e essencial para aumentar a produtividade da cultura. Esta medida, além de não elevar os custos de produção, principalmente, pelo baixo custo relativo do insumo,...

No Piauí ocorrem vários tipos de virus, a EMBRAPA, através da sua Unidade de Pesquisa (UEPAE de Teresina), conduziu mais um projeto de melhoramento de feijão macassar, visando a obtenção de cultivares com resistência múltipla às viroses, com bom potencial de rendimento e com grãos de boa qualidade comercial. A BR 12 apresenta resistência ao virus do mosaico rugoso do caupi, ao virus do mosqueado severo do caupi, ao virus do mosaico severo do caupi e ao virus do mosaico dourado do caupi. Reune, portanto, as resistências presentes nos genótipos parentais. Além disso, a cultivar BR 12 Caninde possui boas características agronômicas, com vagens e sementes na faixa de aceitação de produtores e consumidores.

Autores: CARVALLO GUERRA, H. O.; SOARES, J. M.
Este trabalho foi conduzido no Perimetro Irrigado de Bebedouro, Petrolina, PE, no período de setembro/dezembro de 1983. O trabalho constou da avaliação do manejo de água em três lotes distintos de colonos. Cada lote foi aleatoriamente distribuido dentro de uma mesma mancha de solo, de modo a contemplar as unidades 37 AA, 37 AB e 37 BB de selo do tipo Latossolo Vermelho-Amarelo. Selecionou-se a cultura do feijão caupi (Vigna sinensis) por ser uma cultura base neste período. Em cada lote, fêz-se três coletas de dados ao longo do ciclo fenológico do feijão, assim discriminadas: a primeira, em outubro (durante o estádio inicial de feijão) a segunda, em novembro (início de floração) e a terceira, em dezembro (final do ciclo). Constatou-se que as vazões médias...

Com a expansão de plantios de seringueira no Estado, novas doenças fúngicas surgiram. Os vários patógenos atacam simultaneamente os folíolos jovens, danificando-os e/ou causando sua queda. Objetivando selecionar alguns fungicidas capazes de controlar eficientemente esse complexo de doenças fúngicas, realizaram-se ensaios, durante dois anos, em uma área de 8 ha formada pelo clone IAN 717, com idade de oito anos.

A irrigacao por inundacao e uma pratica utilizada tanto para a exploracao de terrenos cuja declividade nao exceda 1% e para pequenas manchas de solos situadas nas baixadas ao longo das margens dos rios, cuja topografia se apresenta bastante irregular. As diversas modalidades de irrigacao por inundacao, podem ser empregadas para a exploracao da rizicultura, fruticultura, pastagens ou cereais, dependendos dos tipos de solos (argiloso ou arenoso). O sucesso da irrigacao por inundacao depende do dimensionamento correto e do manejo eficiente do sistema projetado. As informacoes basicas referentes ao solo, suprimento de agua, culturas a serem exploradas e o clima podem proporcionar o dimensionamento tecnico e economico desse metodo de irrigacao.

Os animais foram mantidos em pastagem nativa de caatinga raleada. Na avaliacao quantitativa do semen, encontrou-se maior volume na estacao chuvosa do que na seca. A concentracao de espermatozoides no ejaculado foi inversamente proporcional ao volume, portanto variando com as epocas do ano. Na estacao seca a porcentagem de espermatozoides vivos foi menor do que na estacao chuvosa. A patologia espermatica foi maior na estacao seca do que na chuvosa, porem essa patologia estava dentro do limite permitido(20-25%) para se obter uma taxa de fecundacao satisfatoria em qualquer das estacoes.

Provedor de dados: 14
Autores: CAMPOS, I. S.; GAMA, E. E. G.; MAGNAVACA, R.; LODI, N. V.
Embora o milho seja plantado em todo o Estado do Acre, a produtividade alcançada nas lavouras deste cereal é muito baixa (aproximadamente 1.280 kg/ha) em virtude da predominância dos sistemas de cultivos consorciados, qualidade inferior do material genético e das sementes utilizadas. Com o objetivo de obter material genético com características requeridas para as condições de clima, solo e cultivo do milho no Estado do Acre, foi desenvolvido um trabalho de melhoramento do genótipo CMS 06, proveniente do Centro Nacional de Pesquisa de Milho e Sorgo (CNPMS).

As cigarrinhas-das-pastagens, pelos prejuízos que vem causando a pecuária nacional, reduzindo a capacidade de suporte das pastagens, constituem-se pragas que muito tem preocupado aos produtores e as autoridades governamentais pelo montante de carne que deixa de ser produzido em função dos danos impostos por estes insetos. Dentre os seus inimigos naturais, o mais promissor tem sido considerado a mosca Salpingogaster nigra Schiner, cujas larvas alimentam-se das ninfas das cigarrinhas radicolas, ou seja, daquelas cigarrinhas cujas ninfas se desenvolvem junto as raízes e/ou a base dos caules das plantas.

Comportamento produtivo de caprinos de aptidão mista no Acre.
Provedor de dados: 14
Autores: DIAS, R. P.; COSTA, A. L. da; MOREIRA, P.; VALENTIM, J. F.; SILVA, C. de S. e.
A caprinocultura nacional, atualmente, é representada por aproximadamente 9 milhões de cabeças, sendo que deste total, 92% encontram-se no Nordeste do Brasil, representando um componente dos sistemas de produção dos pequenos produtores dessa Região. No Acre, em face da produção irregular de proteínas de origem animal pelos pequenos produtores, a racionalização da caprinocultura é medida importante. A introdução de caprinos melhorados com padrão racial definido e melhores conhecimentos técnicos de manejo, possibilitarão o oferecimento de uma fonte de proteína de baixo custo, principalmente pela aptidão dupla do caprino em estudo.

Controle biológico de pulgões do trigo.
Provedor de dados: 14
Autores: GASSEN, D. N.
Os pulgões, pragas do trigo no Brasil, são nativos da Ásia e da Europa de onde, provavelmente, foram introduzidos na América. Neste novo ambiente, livres de seus inimigos naturais, atingiram altas populações na década de 70. Em 1978, o Centro Nacional de Pesquisa de Trigo (CNPT) iniciou um programa de controle biológico de pulgões, introduzindo parasitos das regiões de origem da praga.

The multiparameter characteristics of the SIR-C/X-SAR experiment (L, C and X bands, HH, HV and VV polarizations for L and C bands, VV for X band, angles of incidence from 15 graus- 55 graus) would provide an unique and excellent opportunity to improve hydrologic and agricultural studies in the microwave domain. Being so, two main objectives are established in this proposal: a) To develop an algorithm to monitor the hydrological cycle over agricultural areas, based on data derived from SAR imagery and meteorological data at a floodplain area; b) To verify the possibility to discriminate among cultures at the date of the experiment and describe and analyse the attenuation properties of the cultures as related to the following radar parameters: frequency,...

Provedor de dados: 14
Autores: CAMPAGNOLLA, C.; MARTIN, D. F.
O objetivo do presente estudo foi verificar a viabilidade de se utilizar, nas armadilhas com feromônio para bicudo, o inseticida Propoxur 10% sob a forma de pedaços de coleiras antipulga e carrapatos, para cães, em substituição a plaquetas importadas dos EUA contendo estes inseticidas. Para isso foram utilizados dois tipos de armadilhas, uma com um cone de tela de arame (nacional) e outra com um cone de plástico de 12 furos de 2 mm de diâmetro em disposição circular (importada, modelo Hardee). Para cada tipo de armadilha considerou-se três situações: sem inseticida, com Propoxur 10% formulado em coleira e com Propoxur 10% formulado em plaqueta, o experimento foi instalado em 4 blocos ao acaso com parcelas subdividas, sendo transferidos 10 adultos para cada...

Provedor de dados: 14
Autores: BEZERRA, J. R. C; VELOSO, M. E. da C.; CASTELO BRANCO FILHO, H.
A cultura do arroz tem lugar de destaque na agricultura piauiense, ocupando, em 1985, o 1o.lugar em valor de producao e o 3o.em area cultivada. Contudo, por ser uma cultura preponderantemente de sequeiro, tem apresentado uma baixa produtividade. A EMBRAPA/UEPAE de Teresina desenvolveu pesquisa na area de melhoramento vegetal com o objetivo de identificar genotipos de alto potencial produtivo e adaptacao as condicoesecologicas do Estado do Piaui. Atraves de ensaios de avaliacao de cultivares/linhagens de arroz irrigado foram testadas varias cultivares emdiversos municipios, dentre as quais destacou-se a Metica 1 que e procedente da Colombia, e que atraves de multiplos cruzamentos foi introduzida no Brasil, pela EMBRAPA/CNPAF, em 1981. A planta tem...

Bulbo infiltrômetro.
Provedor de dados: 14
Autores: NASCIMENTO, T.; SOARES, J. M.
Na irrigação por gotejamento, recomenda-se que a percentagem de área molhada seja obtida em base ao bulbo molhado produzido por gotejadores em condições de campo. Entretanto, muitos sistemas são dimensionados utilizando-se dados tabelados devido a inexistência de equipamentos apropriados. Diante disto, desenvolveu-se um bulbo infiltrômetro que possibilita a determinação do bulbo molhado em testes de campo. Este equipamento é constituido de três partes: 1. Reservatório; 2. Coluna de nivel constante e 3. Microtubo. O reservatório de cimento amianto com capacidade para 50 l e apoiado num suporte de madeira e conectado à coluna de nível constante, através de uma mangueira com 1/2" de diâmetro. A coluna é constituida por um tubo de PVC rígido com 0,77 m de...

Autores: CAMPOS, I. S.; FARIAS NETO, J. T. de; GAMA, E. E. G. e; LODI, N. V.
A baixa produtividade de milho no Acre deve-se, principalmente, à pequena oferta de material genético melhorado, ao tradicional cultivo em consórcio, ao urgente espaçamento entre plantas decorrente do uso de cultivares de porte alto e problemas relacionados com beneficiamento, escoamento e comercialização. Dessa forma, a UEPAE Rio Branco está desenvolvendo um trabalho com o objetivo de avaliar o comportamento vegetativo e produtivo de cultivares e híbridos de milho, nas condições de clima, solo e de cultivo no Acre, selecionando material genético de porte baixo ou médio, com alto potencial produtivo, com boa tolerância ao acamamento e às principais doenças e pragas da cultura e com tipo de grão que atenda às exigências dos consumidores.

Agriculture, conchyliculture et circulation des eaux de surface : état actuel des recherches
Provedor de dados: 5
Autores: Chevallier, Claude; Masson, Daniel.
La qualité des eaux de surface constitue périodiquement un sujet de controverse et de polémiques entre professionnels agricoles et conchylicoles charentais. Le débat reste centré sur la valorisation agricole des zones de marais littoraux. La création croissante d'îlots de culture drainés, souvent à proximité immédiate des zones conchylicoles, suscite l'inquiétude quant à la qualité des eaux d'aval. Il nous a paru nécessaire d'établir un état succinct des connaissances en la matière afin d'éviter l'usage d'arguments parfois irrationnels et de favoriser le dialogue entre les partenaires ; mais il nous paraît tout aussi important de montrer que la qualité des eaux de surface, question essentielle pour l'aménagement régional dépasse le seul cadre des marais :...

Tidal-induced pulses in the flow through the Strait of Gibraltar
Provedor de dados: 5
Autores: La Violette, Pe; Lacombe, H.
Ship data collected in the 1960s and recent data from ship, aircraft and satellites indicate that the flow in the Strait of Gibraltar does not move in the form of continuous currents but as tidal-induced pulses. A descriptive model based on these data is presented. The model indicates that the pulses are a result of increases in the speed of the tidal streams as they encounter the constrictions of the regional bathymetry (especially the Camarinal Sill and between the Camarinal Sill and Tarifa). Periodic increases modify the regional flow so that during each tidal cycle, the eastward-flowing surface Atlantic water and westward-flowing deep Mediterranean water are alternately emitted as large pulses into the Mediterranean Sea (Atlantic water) and Atlantic...

The State's main lines of action in the maritime fishing sector are not at all specific. They aim to define, among others, the regulation of relations among the different actors within the sector as well as the technical and administrative methods of management (Wehrin H, 1987). In terms of halieutic resources, the European Community has partially taken the place of state power to set, in particular, rules of management and exploitation of the stocks. The TAC and quotas, keys of resource distribution, and the market policy set up through producer organisations, are indications of this substitution in progress. The recent request coming from the European Community for reducing the fishing effort is witness as well of this transfer in progress (decision of...

Elevage semi-intensif de Peneus japonicus dans les marais de l'Atlantique
Provedor de dados: 5
Autores: Brault, Anne-marie.
Les premiers essais d'élevage de la crevette Pénéide P. japonicus ont eu lieu dès 1967 sur les côtes françaises à partir de post-larves importées du Japon. De 1971 à 1980, de nombreuses tentatives d'élevage ne fournirent pas de résultats transferrables. Depuis les années 80 la production en post-larves étant maîtrisée et un granulé de qualité et de prix satisfaisant était fabriqué industriellement, la station IFREMER de Noirmoutier a entepris des tests de grossissement en extensif et semi-intensif. Les résultats ont montré que la crevette pouvait être élevée dans les marais Atlantiques. Ceux-ci  connaissent souvent une crise économique liée au déclin de la saliculture et à la faible valeur agronomique des terres. Les atouts de la crevette sont nombreux : -...

Dispersal of organisms at deep-sea hydrothermal vents: A review
Provedor de dados: 5
Autores: Lutz, R A.
Modes of larval dispersal at hydrothermal vent sites (21 degree N, 13 degree N and the Galapagos Rift) have been inferred for mollusks from the morphology of the larval shell. Only three have morphologies indicative of planktotrophic development (one mytilid and two turrids); the larval development of the remaining species appears to be nonplanktotrophic. Among the hydrothermal vent crustaceans, two (the galatheids Munidopsis cf. subsquamosa and Minidopsis lentigo ) appear to have nonplanktotrophic development, whereas both the brachyuran Bythograea thermydron and the caridean shrimp Alvinocaris lusca apparently have widely dispersing planktotrophic larval stages. Results for polychaetes suggest a similar variety of reproductive adaptations. Although a few...

Flux de carbone en milieu pelagique de Mediterranee occidentale lors de la floraison printaniere

Autores: Jacques, G.
Data from the Mediprod 1 cruise (March-April 1969), together with the appropriate conversion factors, were used to calculate carbon flux in the pelagic ecosystem, following fertilization due to vertical winter mixing. In the space of one month, 13.7 gC multiplied by m super(-2) are produced by the phytoplankton, one quarter (3.4 gC multiplied by m super(-2)) of which corresponds to a rapid regeneration of nutrients within the euphotic layer mainly by the way of zooplankton. One quarter of the production (3.4 gC multiplied by m super(-2)) is used by the phytoplankton to increase its biomass. The remainder of the photosynthetic carbon (10.3 gC multiplied by m super(-2)) is exported outside the primary producers box. About one half (5.2 gC multiplied by m...

Summer zooplankton metabolism and its relation to primary production in the western Mediterranean
Provedor de dados: 5
Autores: Alcaraz, M.
Oxygen consumption and excretion rates for ammonia and soluble reactive phosphorus (SRP) by mesozooplankton were studied at a series of stations located along a transect between the islands of Mallorca and Menorca during July 1983. As in a previous cruise also made during the summer stratification period (July 1982), vertical profiles of zooplankton biomass showed the existence of a zooplankton maximum, coinciding with the chlorophyll, phytoplankton and super(14)C fixation maxima. The mean zooplankton excretion in the epiplankton layer can provide 13.7-16.8% of the N (as ammonia) and 67.2-76.6% of the P (as SRP) requirements for primary production, assuming a mean carbon-to-nitrogen assimilation ratio (C/N) of 6.65, equal to the mean C/N ratio of the...

Autores: Le Goff, Pierre-yves.
At the end of the Second World War, a process of modifications to the production framework of the small fishing business sector began. This reorganising of the sector was oriented towards capital deepening, thus bringing on a change of the weight of various production factors. In fact, while the number of ships and sailors was decreasing, the power, size and gear of the small boats were increasing. The landed amounts lagged, even if a qualitative change in intake appeared, which brought, along with rising demand, an increase in current francs of the landings' value (MEURIOT, 1987).  This technical evolution of the ships was largely helped by the effect of successive changes in the financing of production units and the effect of the positive changes of the...

Permanent features of the circulation in the Catalan Sea
Provedor de dados: 5
Autores: Font, J; Salat, J; Tintore, J.
Through the analysis of hydrographic data collected during 16 cruises (1975-1985), we identify and describe the seasonal characteristics and the permanent features of the circulation in the Catalan Sea (north-western Mediterranean). Two fronts follow the continental shelf break on the peninsular and Balearic sides, separating the central dense waters from the surrounding lighter waters of Atlantic and continental origins. One is mainly produced by strong salinity gradients (Catalan front) and the other by temperature gradients (Balearic front). Two currents are associated with these fronts: the southwest Catalan current and the northeast Balearic current. Strong vertical mesoscale motions have been observed on several occasions in the weakly stratified...

Compétition internationale et politiques nationales dans les transports maritimes
Provedor de dados: 5
Autores: Shuo, M.
The evolution of technology and labor costs in maritime countries results, throughout the international competition, in a transfer of shipping from developed countries to some newly industrialized countries, although the protectionism and the international cooperation can modify, liule or more, this tranfer. [0 make the maximum profit from shipping industry for the national economy, a new maritime policy is supposed to be worked out in line with such an evolution, so as to decide when and how the government should be involved. That policy ought to have three stages concerning successively the preparation, the development and the retreat of shipping industry. A merchant fleet is often considered to be a constitutive element of national sovereignty....

Following a mission made by J.P. George on board trawls testing tunny fishing by using a pelagic "boeuf" trawl in September 1987 (because these tests were very promising), IFREMER became interested in designing a trawl more adapted to this type of fishing, known as surface fishing, it was therefore decided to create a mock-up to scale of the trawl that folds down from the bottom.

Mortalités d'huîtres japonaises sur le Banc de Ronce Les Bains : rapport provisoire au 4/8/88
Provedor de dados: 5
Autores: Bodoy, Alain; Garnier, Jacqueline; Geairon, Philippe; Chagot, Dominique; Grizel, Henri; Comps, Michel; Razet, Daniel.
Depuis le mois de juin 1988, les ostréiculteurs ont fait part de la présence de mortalités importantes sur le banc de Ronce (bassin de Marennes-Oléron), d'abord auprès de l'Ifremer et des Affaires Maritimes, puis des pouvoirs publics. Ces problèmes ont été évoqués lors d'une réunion en Préfecture de Charente-Maritime, le 4 juillet 1988. Il s'est alors avéré nécessaire de réaliser un constat de la situation notamment sur le banc de Ronce, et de faire le point sur les causes pouvant être à l'origine de la situation sur les mortalités survenues dans cette zone. Cette décision a été confirmée le 12 juillet, lors d'une réunion à la Sous-Préfecture de Rochefort. Le présent rapport présente les résultats scientifiques actuellement disponibles, ainsi que les...

Elevage, pêche et programmes d'étude des stocks du "Lambi" Strombus Gigas (gastéropode : strombidae) dans deux pays de la Caraibe : Iles Turks et Caicos, Porto Rico
Provedor de dados: 5
Autores: Rathier, Isabelle.
Le lambi, Strombus gigas (Gastéropode : Strombidae) est une ressource exploitée traditionnellement dans les région Caraibe. D'après de nombreux auteurs, l'abondance des stocks a diminué depuis une vingtaine d'année. C'est le cas à Porto Rico, dont la production a de toute façon toujours été insuffisante pour satisfaire la consommation locale. Aux Iles Turks et Caïcos, où la production de lambis est l'une des plus fortes de la région Caraïbe, il y aurait danger de surexploitation. Ces deux pays ont pour objectif la mise en place ou l'amélioration de règlementions de la pêche.

Estimation des stocks de moules (Mytilus edulis L.) de gisements naturels et de culture sur bouchots dans la baie de Bourgneuf (Année 1988)
Provedor de dados: 5
Autores: Lefrancois, Josiane.
La présente étude cherchera à estimer : - le stock de moules de gisements naturels et son évolution par rapport aux précédentes évaluations réalisées au cours des années 1986 et 1987 - le stock de moules cultivées sur bouchots dont l'importance relative par rapport à l'ensemble des bivalves de la baie n'est pas connue; De plus, le choix et la mise en oeuvre d'une stratégie d'échantillonnage propre à chacune de ces estimations seront discutés. Enfin, une explication des intéractions entre les différents stocks de bivalves connus sera tentée, débouchant sur des propositions de mesures de gestion propres à améliorer la croissance des coquillages en baie de Bourgneuf.

Mytiliculture en mer ouverte. Estimation des possibilités de développement sur le littoral Nord-Pas-de-Calais
Provedor de dados: 5
Autores: Morel, Marc; De Ponteves, Mary-brigitte.
Avec une production d'environ 60 000 tonnes en 1986, la France tient la troisième place en Europe parmi les pays producteurs de moules, arrivant derrière l'Espagne et les Pays-Bas. Cependant, pour satisfaire à la demande intérieure, notre pays doit importer presque autant de moules qu'il n'en produit. Afin de diminuer le déficit de la balance commerciale, des possibilités de développement de la mytiliculture ont été étudiées. C'est dans ce cadre que des essais d'implantation de culture de moules sur bouchots ont été entrepris sur le littoral Nord-Pas-de-Calais. Face à la rareté des sites potentiels d'implantation de bouchots un peu partout en France, une nouvelle voie s'est ouverte avec la production de moules cultivées vers le large, dans la bande des 3...

Un Pectinacea (Bivalvia) tres primitif: Bathypecten vulcani du site hydrothermal de 13 degree N (Pacifique oriental)
Provedor de dados: 5
Autores: Schein-fatton, E.
Bathypecten vulcani recently discovered in the 13 degree N hydrothermal area on the East Pacific Rise, is small in size, like other deep-sea Pectinacea. The genus Bathypecten is not restricted to this midoceanic ridge, but has another representative on sedimentary abyssal and bathyal bottoms of the East and West Atlantic, Bathypecten eucymatus . The main differences between these species concern microstructure and growth patterns. From its paleozoic affinities, Bathypecten may be considered as another "living fossil" in the East Pacific hydrothermal environment, but it clearly belongs to the adaptive radiation of a group of modern Pectinacea in which the separation between two distinct families is not necessarily justified.

L’Ifremer a mis en évidence dernièrement, des ressources abondantes de petits bivalves sur les côtes bretonnes et de Basse-Normandie. Près de 20 000 tonnes de palourdes roses, spisules et amandes de mer, sont annuellement exploitables sur ces côtes.   Certains bivalves sont habituellement exploités, et cela depuis des décennies : coquilles St Jacques et praires. Une pêche excessive a causé une dégradation du stock de ces bivalves qui constituent encore l'activité essentielle de nombreuses unités de pêche artisanale.

Epizootic diseases of oysters associated with viral infections
Provedor de dados: 5
Autores: Comps, Michel.
Virus infections have been associated with major diseases of oysters of the genus Crassostrea. These infections include gill necrosis virus and hemocytic infection virus diseases of the Portuguese oyster C. angulata and more recently the oyster velar virus disease affecting larval, hatchery-reared Pacific oysters C. gigas. This report presents histo- and cytopathological characteristics of these infections in which large icosahedral cytoplasmic deoxyriboviruses, similar to the iridoviridae, are implicated, The gill necrosis virus causes, principally in the Portuguese oyster, an evolutive ulceration of the gills, including cellular hypertrophy and severe inflammation. Mortalities have been observed in the most serious cases. Hemocytic infection virus has...

Autores: Berland, B R; Benzhitski, A G; Burlakova, Z P; Georgieva, Lv; Izmestreva, Ma; Kholodov, Vi; Maestrini, Sy.
Our hydrological study confirmed that the seawater circulation is of the cyclonic type in the Levant Sea north-eastern zone, in the Algero-Provencal basin southern zone and in the Ionian Sea around the strait of Otranto. The seawater circulation of the Creto-African area is of the anticyclonic type. The following hydrobiological profiles of the upper 500 m seawater layer were typical of these areas during summer: a homogeneous, superficial (10-25 m), warm seawater layer limited by a pronounced thermocline gradient, the salinity of which increases; an Atlantic seawater mass: 15 to 40-50 m deep in the two oriental polygons and to a depth of 200-500 m in the Ionian Sea and in the Western Mediterranean; and a Levantine seawater mass.

After four weeks' stabulation, at temperatures ranging from 30°C to 10°C for a given level of food (2.10 cells of Chaetoceros calcitrans.1(-1) ), a study of the growth and evolution of the biochemical contents of the oyster Crassostrea gigas showed a negative effect of high (30°C) and low (10°C) temperatures on growth; levels of total glucid and glycogen were inversely proportional to temperature and related to gametogenesis. At the same time measurements of the filtration rate, respiration and food consumption done at different levels of food (10(6) to 8.10(7) cells.1(-1) showed a better adaptation of the oysters to 20°C after one month.

Etude sanitaire (1984-1986) de la rivière de Pénerf (Morbihan)

La plus grande partie des marais de la rivière de Pénerf a été classée insalubre en 1941. Il importait d'en revoir le classement au vu des normes de salubrité précises (définies seulement depuis 1976) et parce que leur potentiel aquacole parait de plus en plus intéressant. Malgré quelques signes d’alarme la salubrité de la rivière est globalement acceptable. Les zones insalubres elles-mêmes, bien que légèrement hors normes, ne paraissent pas d'une qualité rédhibitoires pour l'élevage de coquillages si l'on admet que ceux-ci peuvent être décontaminés ensuite par reparcage en zone salubre (contaminations non irrémédiables). Enfin le marais de Saint-Guérin pour lequel il existe des projets de claires d'affinage, apparaît tout à fait conforme et serait donc à...

The estuary of Charente can be considred as a vast natural zone of mixing brackish waters and marine waters of Marennes-Oleron. One part of the cruises engaged from October 1985 to November 1987, allowed to dfine the main hydrobiological features of the estuary and to estime the input of the river Charente. Cruises permitted to establish the general hydrobiological schema of the estuarine bay and showed that the river Charente does play a part in the salinity and nitrogen inputs on marine waters.

Difficulties in sampling for estimation of phytoplankton biomass in estuarine conditions : variabilities and precisions at different temporal scales in the case of the bay Marennes Oleron
Provedor de dados: 5
Autores: Heral, Maurice; Goulletquer, Philippe; Razet, Daniel; Prou, Jean; Ravail, Brigitte; Maestrini, Serge.
Different sampling strategies have been tested for estimation of phytoplanktonic biomasses in a bay submitted to estuarine conditions and high velocity of currents. Daily variations showed that for a precision of 5% of the daily mean, it is necessary to sample with a 1 hour and a half time scale. Systematic sampling appears to be more preceise than the random sampling. A sampling during 35 days at low tide and at high tide, during the phytoplanktonic bloom, showed the large variability between the days. A precision of 30% of the mean biomass of the month is obtained with a 8 days time scale. Comparison between tidal cycle sampling (10% of precision) with a punctual sample in the middle of the day did not show large differences. As the main variability is...

Autores: Belin, Catherine; Berthome, Jean-paul.
In 1986, 23 discolored waters were observed ; dinoflagellates often were the cause of them. Many developments of Prorocentrum minimum occured ; two of them were associated with shel1fishes mortalities. At contrary, other species which are suspected to be toxic for shellfishes, as Gyrodinium aureolum and Gyrodinium spirale, have not been associated with mortalities, although they have been observed in several areas.  The developments of Dinophysis (cf. acuminata or sacculus) caused provisional prohibitions of shellfishes selling, especially in the south of Brittany. Another specie was also implicated in toxicities : Prorocentrum lima. Human intoxications and economic consequences were rather important.

Carboxylase activities and carbon isotope ratios of Mediterranean phytoplankton
Provedor de dados: 5
Autores: Descolas-gros, C; Fontugne, M R.
Phytoplankton constitute the medium whereby carbon is transformed from the inorganic to the organic state in pelagic ecosystems. In terrestrial plants, the super(13)C/ super(12)C ratio of the organic matter (expressed as delta super(13)C) is a good indicator of carbon pathway. We measured this ratio together with three carboxylase activities: ribulose-1,5-bisphosphate carboxylase, phosphoenolpyruvate and phosphoenolpyruvate carboxykinase on Mediterranean phytoplankton communities. Results were obtained in the field during the Phycarb cruise in February 1984 and during the Epice experiment in a simulated enclosed water layer at Villefranche-sur-Mer in November 1984. These data were compared with those obtained previously on temperature phytoplankton (diatom...

The french Guyana sh rimp fishery has grown from the sixties, following the development of US a nd Japanese fleets. The EEZ delimitation in 1977 and the french policy towards promotion of french vessels allowed, since 1980, the emergence of french ship-owners. The paper analyses the recent economie evolution of the enterprises and underlines first the importance of this activity within regional economy, and second its dependance on imported inputs. The french policy leads to an incrcase of the share of the net added value that remains in the depanment, but it also come to a poor financial status of the french ship-owners. The data collected and given in this paper will be used to feed a bio-economic model o f the shrimp fishery.

The growth potential study of waters of the Vilaine bay was realized from march to september 1987 and for three sampling stations. The growth of depleted test cells of Skeletonema costatum was estimated and compared from existing nutrients pools for aIl water samples. As a first result it appears that inorganic nitrogen could stimulate the growth during spring while no clear relationship is observed between the algal growth and other hydrological parameters during spring or summer periods. Nevertheless these first results need further corroboration.

The aim of this report is to provide biomass estimates (AFDW, g.m-2 ) of the four main components of the benthic food web in the southern part of the Bay of St-Brieuc: suspension-feeders, deposit-feeders, herbivores and carnivores. Patterns in the environmental data (i.e., sedimentary characters) are first analysed, and then related to the spatial distribution of communities ; both approaches use classical ordination techniques (PCA, correspondence analysis). A second typology, based on a review of published litterature concerning coastal macrozoobenthos feeding, ascribes each taxonomic unit to a trophic group. Finally, quantitative results are thus given per biota ; suspension-feeders appear to dominate (in terms of biomass) most of fine-sand habitats of...

Digestibilité des protéines et disponibilité des acides aminés de quelques matières premières chez le bar (Dicentrarchus labrax)
Provedor de dados: 5
Autores: Spyridakis, P; Gabaudan, J; Metailler, Robert; Guillaume, J.
Protein digestibility of soyabean meal, casein-gelatin mixture and fish hydrolysate was tested in the European sea bass, using increasing substitution levels in a reference diet. The protein digestibility of the latter composed of Norwegian fish meal had already been established (91 %). An accurate estimation of the apparent digestibility coefficient was made by linear regression, for the casein-gelatin mixture and soyabean meal, but not for fish hydrolysate (non significant correlation, p &gt; 0.05). Protein digestibility estimated by extrapolation varied with the substitution level. The estimations obtained with the highest level used for each ingredient were close to those obtained by linear regression. However they exhibited a high variability for...

Premieres observations sur la meiofaune des sites hydrothermaux de la dorsale Est-Pacifique (Guaymas, 21 degree N) et de l'Explorer Ridge
Provedor de dados: 5
Autores: Dinet, A; Grassle, F; Tunnicliffe, V.
The main characteristics of the meiofauna collected at three hydrothermal sites of the East Pacific Rise and Explorer Ridge are presented. Few differences are observed among the populations of the different areas, which are basically composed of nematodes, siphonostomes, poecilostomes and harpacticoid copepods, ostracods and macrofaunal juveniles (polychaetes and limpets). The Guaymas Basin meiofauna is patchily distributed and species composition varies according to the pattern of flux of hydrothermal fluid through the soft sediments. Measurements of the physico-chemical variability on the vent waters encountered of Explorer Ridge illustrate that very few meiofaunal species are adapted to H sub(2)S-rich and hot environments.

L'economie d'un secteur aquacole : la crevette imperiale sur le littoral Atlantique
Provedor de dados: 5
Autores: Weber, Jacques.
Japanese sand shrimp (Penaeus japonicus) breeding started in 1984 in Charentes and in the Loire region. It is an activity that is still experimental, as much from a technical point of view as biological and commercial. Although the number of farmers and the surface area farmed are increasing rapidly, the average surface area and yields remain very low; high sales prices due in part to the weakness of production, and in part also to the fact that the shrimp are marketed live, depending on short distribution channels. In this short document, it is a more a matter of anticipating the assets or obstacles to the future creation of a business sector, of highlighting the key points on which attention should be focused, than it is analysis of a sector that is,...

Les pigments respiratoires de la faune inféodée à l'hydrothermalisme océanique profond
Provedor de dados: 5
Autores: Toulmond, A; Frescheville, J; Frisch, M-h; Jouin, C.
Examples of the two main classes of circulating respiratory pigments (heme pigments and hemocyanins) have been found in four typical members of the deep-sea hydrothermal vent communities. The studies now in progress concern the hemoglobin of Calyptogena ; the erythrocruorins of Alvinella and Riftia ; and the hemocyanin of Bythograea . This paper summarizes the available data of the molecular structure of these pigments and the functional properties allowing some of them to fix and transport oxygen, sulphide and carbon dioxide. The erythrocruorins of Riftia are the most conspicuous of these respiratory proteins since they seem to be able to carry oxygen and sulphide simultaneously, these substances being fixed at two different sites of the pigment molecule.

Les pêcheries mixtes de langoustine et merlu du Golfe de Gascogne, modélisation bio-économique et simulation des procédures de gestion
Provedor de dados: 5
Autores: Charuau, Anatole.
Fishing crayfish on the gulf's mudflats is a traditional business practised by 450 boats of 12 to 18 metres in length and employs 2,500 sailors. In the north of the gulf, this activity is exclusive, in the south, immature hake are also caught, because the crayfish areas coincide, in part, with the nurseries of the northern stock of this species.   Management of these fisheries, called mixed, of crayfish and hake is one of the greatest problems of the Gulf of Gascony. All assessments tend to show the responsibility of the crayfish boats in the future of the hake stock. The solution is likely to pass through a generalised increase of the 80 mm meshing that would lead, eventually, the hake stock yield to its maximum, but would eliminate a great many trades...

L'élevage de l'huître creuse à Marennes-Oléron en 1987 : Estimation des stocks cultivés
Provedor de dados: 5
Autores: Bodoy, Alain; Geairon, Philippe.
Le bassin de Marennes-Oléron est le premier centre ostréicole de France, avec un stock de 93 700 tonnes en août 1987. L'opération d'échantillonnage a montré que ce chiffre comprenait 36 500 tonnes pour l'élevage à plat, 33 000 tonnes pour la première phase d'élevage sur tables, qui concerne l'élevage sur collecteurs de captage et 24 200 tonnes pour la phase finale représentée par l'élevage en poche. Le niveau du stock est en augmentation constante depuis 1984. L'importance pondérale de chaque classe d'âge est susceptible de fluctuer très largement puisque des huîtres âgées de 1 an représentaient 4 400 tonnes en 1987, alors que la classe d'âge correspondante représentait 17 000 tonnes en 1986. Ceci est dû aux variations annuelles du captage. Une méthode...

Autores: Gondeaux, E.
The fishing fleet ana lysis and search of classification criteria are required by the inshore fisheries complexity. For the Mor-Braz fishing fleet, boats ordination and structuration are based on analysis of their seasonnal activity on an annual basis. This is to identify fishing entities or types: Used for their descriptive properties, and linked with cluster analysis, ordination methods appeared as to be powerfull tools. As well as typological studies, studies of the fleet dynamic become easier by these methods. Lastly, the proposed typology which indicates a relation between activity type and individual boats location can be used to improve sampling patterns.

Studies of the gill, digestive gland, and gonads of a large mytilid from the 13 degree N hydrothermal vent site have led to insights concerning the histology and functional anatomy of the gill, as well as the role of this organ in the nutrition of the bivalve. From observations of the digestive gland, it is concluded that this mytilid ingests bacteria, as well as other microscopic organisms of hydrothermal vent and euphotic surface water origin. Histology of the gonad reveals that reproduction in this species is similar to that of shallow-water coastal bivalves.

The sedimentary sequences over the Raggau Basin, a major feature of the central part of the Southern Kerguelen Plateau, are more than 3 km thick and are divided into two megasequences. The lower megasequence appears very thick in the cent.rai part of the basin and thins towards the SE due to erosion at its top. The upper megasequence is about 1.5 km thick. A discordance at the lower part of the megasequence marks an episode of tectonic extension, characterized by normal faulting, which probably corresponds to the...

Monthly landings of the offshore fleet analysed from logbooks for the period 1985-1987 indicate changes in fishing areas. The mean length of males, the mean length of females and the sex-ratio have been analysed by Principal Component Analysis in 1981-1987 samples. The heterogeneity between catches from different statistical rectangle (30 x 40 nautical miles) was great enough to deduce a way of raising composition from samples to total landings. It also offers the possibility to verifiy and correct declaration on geographical origin of landings.

As part of the multidisciplinary programme ECOMARGE (ECOsysteme des MARGEs continentales) an experiment to measure vertical flux of particles was carried out in the golfe du Lion off Banyuls-sur-Mer (Lacaze-Duthiers canyon) over a period of 17 days in autumn 1983. Sediment traps were deployed at depths of 100, 200 and 315 m in a water column 350 m deep. The trapped material appeared to consist of fine muddy sediment and numerous biogenic debris. Total mass flux increased linearly with depth from 4 g m super(-2) day super(-1) at 100 m to 13 g m super(-2) day super(-1) at 315 m. The lithogenic fraction was predominant at all depths (55 to 60% of total mass flux). Trap-collected fecal pellets were categorized by different shape classes and enumerated. Mass...

Autores: Fustec, A; Desbruyeres, Daniel; Laubier, Lucien.
Authors used photogrammetric and videogrammetric data collected at 13 degree N/EPR by the French manned submersible Cyana during the Biocyatherm and Biocyarise cruises to estimate the biomass of vent fauna. Two distinct faunal assemblages are associated with low- and high-temperature vents, Vestimentifera. The former, characterized by giant tube worms and bivalves, the latter by the so-called "Pompeii worms" (Alvinellidae). The cold vent biomass may reach 8.5 kg m super(2), far in excess of the hot vent biomass which amounts to 2.4 kg. Such a difference is linked to higher integrated symbiosis between primary and secondary producers in cold vent assemblages, hot vent secondary production being dependent upon separate ingestion/digestion processes.

Ultrastructure du sillon periostracal du Mytilidae des sources hydrothermales profondes du Pacifique oriental
Provedor de dados: 5
Autores: Petit, H; Le Pennec, M; Martin, J.
The periostracal groove of the deep-sea hydrothermal vent Mytilid presents a particular anatomical structure. The initial pellicle derives from pre-periostracal membranes surrounding a granular material. The individualized pellicle then progresses between the generating cells where it is coated until its extrusion in the growing periostracal groove. After extrusion, the periostracal pellicle is regularly coated by material secreted by the microvilli of the adjacent periostracal groove cells.

Transfert, accumulation et regulation des elements mineraux chez les organismes des sources hydrothermales
Provedor de dados: 5
Autores: Cosson-mannevy, M-a; Cosson, R P; Gaill, F; Laubier, L.
Specimens of Riftia pachyptila and Alvinella pompejana were collected during the Biocyarise expedition to hydrothermal vents on the East Pacific Rise at 13 degree N. Quantitative data describing the concentrations of metals in Riftia pachyptila showed that numerous metals are highly concentrated. Analyses of tissues reveal that the plume and the trophosome are the main sites of metal accumulation. Bioconcentration links with the mineral composition of the vent environment are discussed. Mechanisms for metal detoxication were investigated in both species: the presence of metal-rich granules and metallothionein-like proteins were observed. The role of chemolithotrophic bacteria in these mechanisms is discussed.

Autores: Copin-montegut, C.
Chemical analyses of major elements (C, N, P, Si, Al, Fe, Ca, Mg) were performed on more than 500 samples of suspended matter from the western Mediterranean Sea. Four samples collected with a free-floating sediment trap were also analysed. The vertical distribution of particulate organic carbon, POC, reported herein is characteristic of oligotrophic mid-latitude regions. In open waters, the concentration of particulate aluminium is nearly constant. A fraction of particulate silicon Si sub(p) is of terrigenous origin, the rest is biogenic. The biogenic fraction of particulate iron and magnesium is noticeable only in the surface layer, where Fe sub(bio)/POC and Mg sub(bio)/POC ratios are about 10 super(-3). It is not possible to estimate the terrigenous and...

Matiere organique presente dans les eaux d'un site hydrothermal actif du Pacific-Est (13 degree N)
Provedor de dados: 5
Autores: Daumas, R; Alberic, P; Brault, M; Khripounoff, A; Hermin, M-n; Marty, J-c; Saliot, A.
Organic matter present in seawater was investigated in various samples collected in an active hydrothermal site of the East Pacific Rise (EPR) near 13 degree N. During three dives of the submersible Cyana, sampling was carried out at the mouth of active chimneys and near animal communities (Alvinellinae, Pogonophora and Serpulidae). The organic C and total N content of particulate material are higher than the mean concentrations of deep water; combined amino-acids do not show a comparative augmentation, but fatty acids and hydrocarbons are higher in the vicinities of Alvinellinae and Pogonophora than in reference samples or near Serpulidae zones. It is suggested that simultaneous determination of the concentrations of organic substances and bacterial...

Autores: Marcaillou-le Baut, Claire; Le Dean, Loic; Chiffoleau, Jean-francois; Sanjuan, Jane.
Because of the low number of currently available toxicity tests for marine environment, the authors describe an experimental procedure using a marine copepod : Tigriopus brevicornis. This method can be used to quantify the 50 % inhibition of larval production or growth. The variability in controls larval production reaches about 9 %. The toxicity of two contaminants : tributyltin (TBTF) and cadmium chloride (CdCl2) was determined with this method and the 50 % decreases in larval production are respectively 1,4 µg/l (TBTF) and 61 µg/l (Cd++).

Autores: Ge, Chunbin.
This study is devoted to the ecosystem modelling of the lagoon of Thau (France). Two kinds of model were established : determinist models and statistical models. The hydrological evolution is described by a global conceptual model Basin-Lagoon-Sea permitting to determine the basin supply and the exchange volume of water between lagoon and sea. The average temperature of the lagoon is essentially affected by the energy exchange at the air-water interface, it’s evolution is simulated with help of a thermal zero-dimensional model. A biogeochemical model of the phosphorus cycle is connected with the two previous models, this model considers only two stages of cycle: sedimentation and release of phosphorus.

Nutrient sources and primary production in the Eastern Mediterranean
Provedor de dados: 5
Autores: Dugdale, R C; Wilkerson, F P.
The nitrogen budget of the Mediterranean Sea and particularly the eastern basin is constructed from estimates of carbon-based primary production measurements coupled with a model of new production tailored to the circulation pattern of the Mediterranean. New production values provide estimates of the new nitrogen demand for the regions considered and these values are examined with reference to estimates of terrestrial nitrogen inputs to suggest that about 40% of present Mediterranean potential fish yield arises from the latter source.

Autores: Floc'H, Jean-yves.
INTRODUCTION - L'algue Undaria pinnatifida est utilisée au Japon, sous le nom de Wakamé, dans l'alimentation humaine. Elle sert essentiellement dans les soupes, les salades et en accompagnement de plats divers. L'espèce n'était connue jusqu'à ces dernières années que dans les mers du Sud-Est de l'Asie (Corée, Japon, Chine). En 1971, elle a été découverte dans l'étang de Thau, en Méditerranée. On pense généralement qu'elle y a été introduite accidentellement en même temps que le naissain d'huîtres importé d'Extrême Orient (Pérez et al. , 1981). L'espèce s'y est acclimatée et s'y reproduit naturellement chaque année. En 1981, les populations naturelles d'Undaria pinnatifida avaient franchi les limites du bassin de Thau et l'algue était signalée en milieu...

Autores: Gulik, A; Gaill, F.
A freeze fracture morphological study of Alvinella pompejana associated epibiotic bacteria has confirmed the large variety of bacterial species already observed by scanning and thin section transmission electron microscopy. Freeze-fracture reveals striking differences in the membrane structure: The usual fracture along the hydrophobic part of the membrane for some bacteria, but only an unusual cross-fracture through the membrane for others. This suggests that some bacteria contain non-fracturable lipids typical of certain archaebacteria.

Sécurité et conditions de travail à la pêche : petite pêche - pêche côtière - pêche au large
Provedor de dados: 5
This work concerns small-scale vessels, 12 to 18 m long, equipped for small-scale fishing, coastal fishing or offshore fishing. It complements the study published by Ifremer on safety and working conditions in small-scale fishing (vessels longer than 19 m) and in semi-industrial fishing and describes practices other than trawling, such as the use of traps, long lines or gillnets. Often subject to difficult and dangerous operating conditions, these vessels often have substantial safety problems due to their small size and low number of crew. As in our previous study, our research addresses the equipment and the lay-out of the vessels, the use of fishing gear and catch processing, on-board organisation and work schedules, working conditions (noise, lighting,...

The Vestimentifera, their biology, systematic and evolutionary patterns
Provedor de dados: 5
Autores: Jones, M L.
The taxonomy, morphology, and anatomy of the Vestimentiferans are reviewed. The vascularization of the branchial complex and the trophosome is emphasized. A recently discovered ciliated duct, arising from the base of the obturacular region, functional only in juvenile vestimentiferans, is hypothesized as the means of entry of bacteria into the trophosome. Morphological criteria are presented supporting the designation of five families, three orders and two classes, as well as the separation of the vestimentiferans in their own phylum, Vestimentifera, based on the morphology of the opisthosome and the arrangement of anterior coelomic segments.

During the Biocyarise 1984 cruise, individuals of Alvinella pompejana and Bathymodiolus thermophilus were sampled by the submersible Cyana, on the 13 degree N site. Seventy-three heterotrophic bacterial strains were isolated from different body regions of these 2 animals. All the strains are Gram negative rods, most of them are motile. The bacteria isolated from Alvinella epidermis showed the highest index of carbohydrate and amino-acid utilization as sole carbon source. The thermal tolerance of these bacteria is well correlated to the temperatures of the biotopes of these invertebrates. The possible role of these heterotrophic bacteria in the hydrothermal ecosystem is discussed.

Actinies abyssales d'un site hydrothermal du Pacifique oriental
Provedor de dados: 5
Autores: Doumenc, D; Van-praet, M.
The Biocyatherm 1 expedition permitted observation of six species of Hexactiniaria, four of which were collected. Three species collected towards the edge of the site, on its basaltic floor, in areas without thermal anomaly, belong to common deep-sea genera (Phelliactis, Chondrophellia, Actinostola ). The sea anemone collected from the active vents belongs to a new genera of the family Actinostolidae. A few Cyananthea hydrothermala were observed on both chimneys. Ultrastructural investigation of this sea anemone reveals a few bacteria in the phagocytic cells of digestive tissues. Their location and the presence of hydrolases suggest that bacteria form part of the diet of sea anemones and are not symbiotic.

L'economie d'un secteur aquacole : la production de Macrobrachium Rosenbergii en Guyane
Provedor de dados: 5
Autores: Catanzano, Joseph.
Aquafarming in Guyana (Macrobrachium Rosenbergii) finds itself confronted today with a serious economic problem linked to a concurrence of factors of differing origins.  - The absence of markets (an apparently cyclical phenomenon) has hindered many operations and calls into question the producing sector in its current form (See table 5: stock SICA 1987).  But behind this difficulty, other deeper and longer-lasting ones call for questions to be asked. During analysis of the sector, structural blockages appear from the first years of operations, which, combined with the prolonged absence of revenue, accelerates a process of decline (see the spiral of recession in the text). These other factors are: - 1) An environment that hinders the creation of new farms...

Numerical analysis of scale morphology to discriminate between atlantic salmon stocks
Provedor de dados: 5
Autores: De Pontual, Helene; Prouzet, Patrick.
The use of an image analysis microsystem with a specially developed software enabled scale image processing, outline extraction and computation of features which are not available in the conventional approach of scale analysis. Those parameters (shape factors, moment invariants and elliptic Fourier coefficients) were introduced into a discriminant analysis process to test their usefulness in stock identification. The method was applied to European stocks originating from Norway (Etne river) and France (Elorn river). The low misclassification rate obtained indicates that this approach is particularly promising.

Autores: Catanzano, Joseph; Gilly, Bernard; Lantz, Frederic; Durand, M.h.
(Not controled OCR) The economic results of artisanal fishing enterprises are investigated through a sample of 300 to 700 artisanal vessels for which account books are available from 1983 to 1986. The use of economic (such as added value) and financial ratios (solvency and financial autonomy) leads to the identification of four groups of firms. A rough classification has been identified from gears used and areas. Over the period, financial rentability and autonomy show obvious damaging that underlines the relevance of a (current) analysis on the impact of public subsidies on the enterprises behaviour.

Variations locales des populations d'Ulves fixées en Baie de Saint-Brieuc de Juin à Septembre 1986 - Données acquises par vidéo sous-marine
Provedor de dados: 5
Autores: Nedelec, Henri.
Du printemps à la fin de l'été 1986, les peuplements d'Ulves fixées de la baie de Saint-Brieuc sont limités aux fonds présentant une fraction notable de substrat dur. Les Ulves ne semblent pas être à l'origine d'une compétition interspécifique avec les autres macrophytes et représentent en général une fraction infime de la végétation en place. Un recouvrement important des autres taxons limite par contre leur développement. La densité et le recouvrement moyens des Ulves augmentent en général de mai à septembre, cependant, à l'échelle locale, certains secteurs sont privilégiés. On observe au milieu ou à la fin de l'été une réduction de la taille moyenne des individus due en particulier à la disparition des plus grands specimen (vraisemblablement arrachés...

Autores: Loubersac, Lionel; Dahl, Arthur; Collote, Pascal; Lemaire, Olivier; D'Ozouville, Laurent.
Damage from tropical cyclones can have major consequences for coral reef structure and ecology, as well as for human communities and human uses of coral reef resources. Remote sensing with high resolution multispectral satellite images can be used to asses large scale cyclone damages on coral reef areas. SPOT images of the almost atoll of AITUTAKI (Cook Islands) taken in june 1986 and february 1987 after the passage of Cyclone Sally near the island in january, were transformed and subjected to a textural analysis, and then compared to asses damage on the reefs and lagoon.New shallow sand and rubble deposits showed increased reflectance, while lower reflectance seemed associated with damage to reef structure, scouring in the lagoon, deposits of terrestrial...

Autores: Guinot, D.
During the Biocyarise 1984 cruise in the area of deep-sea hydrothermal vents of the East Pacific ridge at 12 degree -13 degree N, Brachyura were collected on various sites. Cyanagraea praedator is represented by two large adult females, caught on the Pogonord site. Bythograea thermydron , and Bythograea microps are also recorded. The very rich precocious stage material permits the formulation of hypotheses concerning regression of the eyes in both Bythograea species from the young and juvenile stages to the subadult and adult stages. The systematic position of the Bythograeoidea is discussed.

Approche de la dynamique de stocks accessoires

Autores: Moguedet, Philippe.
For a few years now, the landings from the Lorient's industrial fleet have been continually increasing (32,000 tons in 1980, 56,000 tons in 1985). This fleet practices a multispecific exploitation of the international fishery of the west and north of Scotland. The rock salmon (Pollachius virens) is the fleets' target species, its catches of other gadidae are considered secondary. Two of the catches, those of the blue ling (Molva dypterygia) and the ling (Molva molva) have been advancing since the beginning of the decade and in 1985 represented 21% of the total amount in quantity and value landed by the industrial fleet. The objective of this study is to asses the status of these ling resources and examine whether their exploitation can, in the short term,...

Réponses et adaptations de la charge énergétique adénylique et l'activité enzymatique digestive à l'emersion chez Crassostrea gigas
Provedor de dados: 5
Autores: Moal, Jeanne; Samain, Jean-francois.
The effect of tidal emergence on the adenylate energy charge value was studied in Crassostrea gigas oysters in Marennes-Oleron Bay. The shot-term AEC responses to aerial exposure differed according to the period of the year. However, on a long-term basis, osters from three bathymetric positions exhibited the same AEC value, but had a different growth rate. The amylase increase observed for the most emerged oysters may play a role in the maintenance of energy equilibrium.

Autores: Heral, Maurice; Deslous-paoli, Jean-marc; Prou, Jean.
After a short bibliographical study of the different approaches for determination of the trophic capacity of a bay for molluscs culture, the authors, with a global mode, show the relations between the growth performance of the oysters Crassostrea gigas in relation with the cultivated stocks. The volumes of consumed and assimilated food are calculated for the stocks in relation with the incoming volumes of water in the bay and the residence time for neap tide and spring tide. The authors find a decrease of growth rate in relation with the volume of consumed food. When it is above 60% and when the volume of assimilated food is above 20%, there is a large decrease of the growth of oysters.

Autores: Devauchelle, Nicole; Coves, Denis.
This paper describes the large-scale production of eggs and larvae of sea bass (Dicentrarchus labrax ) and shows how spawning can be planned to produce viable eggs throughout the year by manipulation of photoperiod and temperature. The rearing temperature was 9.5-22 degree C during spawning and 9-24 degree C during the gametogenesis. The photoperiodic cycles tested were normal (i.e. the photoperiodic cycle observed at Palavas-les-Flots, Mediterranean coast, France, 1984/1987) advanced by 3 to 5 months and delayed by 2 months.

Riftia pachyptila : A highly integrated symbiosis
Provedor de dados: 5
Autores: Felbeck, H; Childress, J J.
The deep-sea hydrothermal vent tubeworm Riftia pachyptila (Vestimentifera) lacks a digestive tract entirely. Nutriments are presumably provided to the animal by symbiotic chemoautotrophic bacteria which are harbored in a specialized organ of the animal, the trophosome. These bacteria are proposed to fix carbon dioxide from the ambient seawater using the energy gained from oxidation of sulfide which is emitted by the hydrothermal vents. The significance of the trophosome for the evolution of the pogonophoran and vestimentiferan body plan is discussed.

The fish fauna of thermal vent areas are identified by observations made from research submersibles and by captures. Two groups of fish may be recognized. The first group comprises fish living exclusively on the hydrothermal sites: These include Bythitidae, and Zoarcidae such as Thermarces cerberus , the principal species on the East Pacific Rise and Galapagos Rift. The second group comprises fish living in the vicinity of vents and in vent areas; its faunal composition seems to consist of species known to inhabit these depths in the Eastern Pacific. The biology of the fish in each of these groups is described and discussed.

A survey of the results of different ultrastructural and biochemical studies on bivalve molluscs found in dense populations on the sites of deep hydrothermal vents of the East Pacific Ridge shows that these organisms demonstrate specific ecological and biological features. The most remarkable characteristic of all species is a well-developed gill, constituting the main organ in the nutritive processes, with a majority of its cells colonized by abundant chemoautotrophic bacteria. Structural modifications related to the utilization of particulate material, as well as structural adaptations attributed to bacterial colonization of the gill, are different in the Vesicomyidae Calyptogena magnifica and the Mytilidae Bathymodiolus thermophilus and Bathymodiolus...

Spectral signatures of the same tropical salt marsh targets, adquired on the ground (Sept 20th 1986) and from altitude (helicopter survey sept 17th 1986) with three looking angles are compared to the SPOT HRV data of sept. 18th 1986 and correlated to some physical properties of the barren salt flats. Those observations give coherent results but, on dense vegetation the satellite response appears under estimated when, on barren flats, it appears over estimated. An atmospheric environmental effect explanation is proposed. Significant correlation between vegetation and brightness and humidity indexes and organic matter of soils are found.

The respective influences of the sediment and of oyster (Crassostrea gigas) farming on the accumulation and the recycling of different forms of organic and inorganic nitrogen are described. Fluxes of dissolved inorganic and organic forms of nitrogen were studied between the water column, the water overlying the sediment and the pore waters, while for particulate forms the fluxes were studied between suspended material, the "biodeposits" (faeces and pseudofaeces of Crassostrea) and the sediment. The flux of inorganic nitrogen amounts to 10.5 106 g.m(-2). Yr(-1), while that of organic nitrogen is half this figure. The particulate flux is 15.106 g.m(-2).yr(-1). On the other hand, the phytoplanktonic nitrogen accounts for only 6% of the total particulate...

Estimation of the mean circulation in the western Mediterranean Sea
Provedor de dados: 5
Autores: Saint-guily, Bsc.
Estimations of the circulation induced by winds and by evaporation have been made with the help of simple analytical models. Three models have been used to compute the mean flow, two for the wind flux, and one for the flux due to evaporation. The resulting quantities, 0.6, 1.3 multiplied by 10 super(6) m super(3)/s for the wind component, 1.5 multiplied by 10 super(6) m super(3)/s for the evaporation component, are of the order of the values obtained from observations. Notwithstanding its secondary importance, the wind contribution appears to be substantial.

Les megalopodes et jeunes stades crabe de trois especes du genre Bythograea Williams, 1980 (Crustacea, Decapoda, Branchyura)
Provedor de dados: 5
Autores: Saint Laurent, M.
The megalopae and juvenile crab stages of two species of Bythograea captured at 13 degree N, Bythograea thermydron and Bythograea microps have been comparatively studied. Comparison with one megalopa from Alvin collections at the Galapagos vents suggests that another species of Bythograea lives there. The "small" megalopae and most of the juvenile crabs cited by Williams in 1980 probably belongs to this new species, herein described as Bythograea intermedia sp. nov., which is presumably restricted to the Galapagos area, and whose size and morphological characteristics set it in an intermediate position between Bythograea thermydron and Bythograea microps .

Etude de la pasteurisation de préparations culinaires à base de produits de la mer. Rapport d'activité. Juin 1987 à juin 1988
Provedor de dados: 5
Autores: Mulak-maillard, V.
La pasteurisation est un procédé de destruction partielle par la chaleur de la flore microbienne, assurant une conservation de plusieurs semaines aux produits, à condition de respecter certaines règles au niveau de la température de conservation (règlementairement fixée à 0°C / + 3°C) et des barèmes de cuisson. Pour déterminer ces barèmes, et pouvoir comparer les effets pasteurisateurs des différents traitements thermiques, il est nécessaire de définir, pour chaque catégorie de produit, la valeur pasteurisatrice minimale à appliquer en fonction de la température et de la durée de conservation. Il faut pour cela, connaître la nature, le nombre et la thermorésistance des germes devant être détruits par la pasteurisation. Dans ce rapport, nous allons :  -...

Nutrient enrichment and circulation of water masses in the Pagassitikos Gulf (Aegean Sea)
Provedor de dados: 5
Autores: Friligos, N.
This paper is concerned with the circulation of water masses and enrichment in inorganic nutrients in the Pagassitikos Gulf, an enclosed basin on the western coast of the Aegean Sea, during 1975-1976 and 1982. The distribution of temperature, salinity and density in the water column indicated the following features: low salinity surface water predominantly related to freshwater runoff; a subsurface water mass, apparently formed by the mixing of fresh with open sea waters; a thermocline; and deep bottom water with open sea characteristics. The seasonal variation in the pattern of surface salinity suggested an anticlockwise water circulation throughout the embayment. The distribution pattern of nutrients and nutrient ratios were compared with previous...

Specimens of hydrothermal vent organisms, Alvinella caudata and Bathymodiolus thermophilus were collected in 1982 from 13 degree N and 103 degree W, on the East Pacific Rise at a depth of 2600 m. The elemental composition was determined for some of their soft tissues at the structural and ultrastructural levels. Two microanalytical methods were used: secondary ion mass spectrometry and X-ray spectrometry. As examples, external and digestive epithelium and lumen of the digestive tract of Alvinella caudata and the gill and digestive gland of Bathymodiolus thermophilus were investigated. Intracellular localization of the elements, performed by electron microscopy, showed that spherocrystals and lysosomes were the target organelles of metal concentration....

Mortalité du tourteau Cancer pagurus provoquée par le dinoflagelle parasite : Hematodinium sp.
Provedor de dados: 5
Autores: Latrouite, Daniel; Morizur, Yvon; Noel, Philippe; Chagot, Dominique; Wilhelm, G.
Unusural crab mortality in winter led us to identify a Hematodinium like parasitic dinoflagellate in the blood of edible crabs Cancer pagurus. Crabs from several fishing areas (the English Channel, the Iroise sea, the bay of Biscay, off Scotland) and from one area of the Channel shore were examined. The crab parasit was found everywhere we investigated and throughout the year. The prevalence which was found independant of the intermolt stage, sex and size of crabs was higher inshore than offshore. The pathogenicity is assumed to differ according to season.

Developpement de la peche de grands pelagiques dans les antilles francaises et organisation du marche des produits de la mer
Provedor de dados: 5
Autores: Lantz, Frederic.
The development of large pelagic fishing in the French Antilles is an integral part of a difficult economic situation of the fishing sector in Martinique where this development can seem like a solution to increasingly acute problems. Indeed, for the regulatory authorities as well as for many participants in the sector, it is imperative to find solutions to the lack of profitability of a part of the fishing ships and to confront the regular increase of the share of imports in supplying Martinique with seafood. This question about the possibilities of developing large pelagic fishing is not new since it is already mentioned in the Notice from the Economic and Social Committee of the Martinique Region in 1982. We will not show in this document a detailed...

Présence d'un Protogonyaulax sp. sur le littoral atlantique français pendant l'hiver 1987
Provedor de dados: 5
Autores: Lassus, Patrick; Bardouil, Michele.
A dinoflagellate belonging to Protogonyaulax genera and forming more than 20 cells chains was observed from November 1987 to February 1988 in Vilaine Bay and in the west ofIle d'Yeu (France). This species was not detected in coastal phytoplankton during preceding surveys. Close to Protogonyaulax affinis it seems to be a winter developing species for this coastal area. Vertical distribution shows in december a migration of the patch towards deeper layers. Increasing occurrences of species belonging to Protogonyaulax (Alexandrium Balech) genera inshore or coastal waters need to pay more attention to the taxonomy of such organisms. Some species are effectively well known as poisons producers.

Autores: Flassch, Jean-pierre.
Introduction: Through the combined works of research, local communities and professionals, a new activity has been created, "vénériculture", i.e. clam farming. Thanks to the knowledge acquired in research as well as production in the shellfish field, clam production results followed shortly thereafter. Rightly so, only 10 years have elapsed since the beginning of the research and the actual production phase (500 t) involving about 300 professionals. Research conducted by IFREMER positively contributes to the creation of new trades as well as diversity within existing professions. Clams are marketed nationally as well as exported. French producers are truly competent, but the prospect of open borders and increasing competition requires maintaining a high...

Les elements nutritifs dans le bassin occidental de la Mediterranee. Bilan des echanges avec l'ocean Atlantique a Gibraltar
Provedor de dados: 5
Autores: Coste, B; Le Corre, P; Minas, Hj; Morin, P.
Nutrient measurements were performed during the Mediprod IV cruise of the R.V. Jean Charcot in the whole western basin of the Mediterranean Sea, special attention being paid to the Alboran Sea and to the Strait of Gibraltar. From these data, new values for the nutrient budget of the Mediterranean Sea are obtained. It appears that dissolved organic nitrogen (DON) contributes to the total nitrogen input in an amount of more than 50%, and that the river runoff contribution accounts for less than 10% of the total nutrient input. High values of the N : P ratio in the Mediterranean Sea (&gt; 20) are explained by the nitrogen and phosphorus content of the superficial layers of the water inflow into the Mediterranean Sea, together with mineralization processes...

Autores: Auclair, Gilles.
Quantitative analysis of trace elements repartition in hydrothermal sulfide minerals has required a development in the method of microprobe analysis. Large investigations on the microprobe analysis conditions (reproducibility, mineral resistance, homogeneity, standards, background measurements, electron beam intensity, accelerating voltage and counting time) allow an improvement of the signal/background ratio during analysis of Se, As, Co, Cd and Ag in chalcopyrite, pyrite, sphalerite, isocubanite and pyrrhotite. Then, a minimal exploitation value has been defined for each element in each sulfide mineral with an analytical accuracy greater than 10%. These values vary from 200 ppm for the cobalt in chalcopyrite and sphalerite to 600 ppm for the selenium in...

Phosphorus and nitrogen in the Mediterranean Sea: Specificities and forecasting
Provedor de dados: 5
Autores: Bethoux, J P; Copin-montegut, G.
The Mediterranean Sea constitutes a small-scale model of a real ocean for studying the fate of trace elements. Peculiarities in the phosphorus and nitrogen cycles permit a better knowledge of the Mediterranean ecosystem and a forecast of their temporal evolutions. The apparent deficit of the Mediterranean nitrogen budget and the abnormally high N/P ratio (compared with the value for the Atlantic) can be explained by a high biological fixation of atmospheric nitrogen, probably due to certain kinds of plankton and bacteria and the presence of Posidonia oceanica and its epiphytes.

As a part of hydrological sampLing operation in South Brittany, 8 transects for 26 sampling stations were made in order to determine horizontal, and vertical distribution of Dinophysis sacculus in the 10 m layer. Un like to 1986, results do not show any correlations between Dinophysis concentrations and stability index. That may, nevertheless, be due to lower cells densities in 1987 when compared to 1986. A thermal, gradient, lower than in 1986, is still observable in the Bouthern of Loire Mouth. And, as a last point, when chlorophyll a concentrations are higher in - 10 m layer than in surface layer (Audierne and Noirmoutier areas), it can be observed hight densities of an other toxie Dinoflagellate : Gyrodinium aureolum .

The document introduces a typology of small fishing companies from the Finistère area based on a factorial analysis of multiple correspondences. This typology is an integral part of the continuation of the study conducted on the economic analysis of small fishing companies. The analysis in multiple components is performed by using the economic criteria of profitability and investment as elements, and as additional variables the structural characteristics (techniques) of the companies. The analysis makes it possible to differentiate companies by their financial parameters on the one hand, and their operating income on the other hand.

A sampling strategy for the estimation of mussels stocks on "bouchots" was elaborated in 1987 and 1988 in the Pertuis Breton area, along the french atlantic coast. This strategy optimizes estimations of number of posts per bouchot, heights of posts wearing mussels, sections of posts and mussels, and eventually densities of mussels, from cost/precision and minimum uptake considerations. The adopted plan is compared to others and the allocation of sampling efforts is optimized.

Diversification de la production conchylicole. Approche d'une stratégie d'élevage de la  palourde japonaise (Ruditapes  philippinarum) dans la  région de la baie de Bourgneuf
Provedor de dados: 5
Autores: Baud, Jean-pierre; Hommebon, Prestal; Haure, Joel.
If clam growth is no longer an issue during the pre-growth phase in the Bourgneuf bay region, the two year growth phase shows several problems: in the south bay area, the growth of Ruditapes phi¿lippinarum clams is inconsistent and depends on oyster and mussel stocks. In fattening ponds raising standards only allow a 500g/m final biomass. This forces clam farmers to own large areas, which are currently hardly available in this region.  The alternative would consist in fractioning the growth phase into two steps: half raising in tidal zones (half buried pots at 2000/ra) or in fattening ponds, under extensive conditions (200/m) or intensive (1000/m) by adding phytoplankton. Winter stocking, for all cases in fattening ponds, would prevent major stress in...

Comparaison de la distribution et du bilan d'echanges des sels nutritifs en Mediterranee et en Mer Rouge
Provedor de dados: 5
Autores: Souvermezoglou, E.
The Mediterranean and the Red Sea are two concentration basins with very similar hydrological characteristics. The water of the adjoining ocean, entering over a sill, holds the water and the nutrient budgets of the basins in balance. Changes in this inflowing oceanic water are analogous in the two basins: reduction in nutrient content, due to mixing with the nutrient-poor water of the basin, biological activity and the existence of successive sills (in the Mediterranean). The Mediterranean receives from the Atlantic Ocean the main part of its nutrient supply (of the order of 70%, the rest being provided by the rivers). This supply is practically constant over the year. The inflowing water from the Indian Ocean provides the entire nutrient supply of the Red...

Japanese clam and hollow oyster spats have been pre-grown under intensive conditions in hatcheries using underground seawater as thermal resource and as source of nutritional salts for forage seaweed production. The main parameters of this environment have been followed up and raising conditions have been controlled (spat density, seawater flow, phytoplankton concentration and temperature). The biological results obtained after interaction processing and the hierarchy of the studied parameters were the object of an economic analysis for each season, comparing different shellfish pre-growth strategies. This study finally allows us to be able to present pre-growth intensive methodology that can be passed on to the professional aquaculture industry.

Gibraltar experiment: A plan for dynamic and kinematic investigations of strait mixing, exchange and turbulence
Provedor de dados: 5
Autores: Bryden, H L; Kinder, Th.
In the past few years, focus has shifted to the study of how the dynamical constraints for flow through a narrow and shallow strait act to control the amount of exchange between the Atlantic and Mediterranean basins. To investigate the dynamics of flow through a strait, a year-long field experiment has been designed to measure the flows through the Strait of Gibraltar, including their time variability over tidal to seasonal time scales, and to assess the importance of friction, mixing, rotation, and nonlinear processes in controlling the exchange through the strait. This field program, called the Gibraltar experiment, will be carried out by a group of American, Spanish, Moroccan, Canadian and French scientists during the period from fall 1985 to fall 1986.

Les compagnes des deux années précédentes après un point zéro et une première année de mise en culture avaient fait apparaître, outre la présence d'insecticides rémanents, une dominance qualitative et quantitative des herbicides aussi bien dans l'eau que dans la matière vivante. Chaque année, des difficultés techniques différentes limitent l'information recueillie,...

Oxygenation physique et biologique de la Mediterranee nord-occidentale en hiver et au printemps
Provedor de dados: 5
Autores: Minas, Hj; Bonin, M C.
Strong vertical mixing during winter in the northwestern Mediterranean Sea occurs with simultaneous ventilation of water masses. In the high turbulent deep water formation chimneys, with homogenous density from the sea surface to the bottom, the oxygen input, limited to the most intense winter period, reaches almost 10 super(3) l O sub(2) m super(-2). From Redfield's exchange coefficient, an oxygen flux of about 12 l m super(-2) d super(-1) can be calculated. Nearly the same flux can be derived from Broecker and Peng's piston velocity data, but in order to reach this value one has to assume that the sea surface film thickness averages 10 mu m. Biological oxygen fluxes produced by photosynthesis or respiration are almost negligible in comparison with the...

Premiers essais d'élevage larvaire de l'ombrine subtropicale (red fish) Sciaenops ocellatus dans les conditions intensives en Martinique
Provedor de dados: 5
Autores: Soletchnik, Patrick; Thouard, Emmanuel; Goyard, Emmanuel; Baisnee, D; Yvon, C; Baker, P.
Two batches of red drum larvae were air shipped from hatcheries in the U.S.A. and stocked in two intensive tank experiments at densities oc 7 :.nd 2-3 larvae per liter. Food items include live rotifers, copepods, brine shrimps. squid and commercial fish pellets. Growth rates were similar in both experiments up to day 20 (12-1" mm) but differences in feeding schedules and an infestation by the dinoflagelate Amyloodinium sp. affected the growth from day 20 to 43 in the second trial. Significant mortalities occurred in the tanks during the first feeding period (days 2 to 7) and again from days 17 to 20 as the result of cannibalism. Survival between day 2 and day 44 was 44% in the first trial. Abnormal inflation of the swim bladder and infection with...

Observation on the feeding behaviour of Crassostrea gigas larvae in the bay of Arcachon (France)
Provedor de dados: 5
Autores: Robert, René; His, Edouard.
Crassostrea gigas Iarvae were collected in the bay of Arcachon in July 1985, 1986 and 1987. Larval samples were collected daily at high tide, during at least the first 12 days of pelagie lire and every hour during 1 day and night cycle, 6 days after spawming. Epifluoreseence microscopy was used for detecting ingestion and digestion of nanoplankton and thin sections were made to try to determine the algal species ingested. The first algal uptake occurred 48 hours after fertilization and different stages or digestion were noted from the 3rd day. No relationship between ingestion or digestion and the age of the viligers was observed. There was no difference in the feeding activity du ring day and night. Because the nutrition index was high (70%) the feeding...

Estimateurs d'indices d'abondance dans le cas d'échantillonnages stratifiés
Provedor de dados: 5
Autores: Bertrand, Jacques; Chevalier, Robert.
One of the primary uses of trawl survey data is the estimation of abundance of the species involved. But these direct estimates give results with generally a high variability. Reducing this latter is one of the main problems for the scientists involved in such a research. Methods to achieve a better efficiency have been implemented. Nevertheless estimations remain highly variable, so the information on the changes in population, enclosed in the observed series of survey indices is mixed with a noise component result of both the survey sampling variability and effect of uncontrolled factors. PENNING'roN ( 1985) proposed time series models to filter measurement error from the signal. However the length of the series does not always allow using time series...

The Scallops' fishery in the bay of Saint-Brieuc has known a fast development from 1962 to 1975. The m anagement measures adopted before 1973 have not been able to avoid a drop in labor and capital incomes. The licence system, set up in 1973, has not improved the economic results in the fishery. The potential patterns of the fishery, in the face of a fluctuating recruitment, are analysed with the-help of a bio-economic simulation model.

Supply of nutrients to the Mediterranean photic zone along a persistent front
Provedor de dados: 5
Autores: Estrada, M; Margalef, R.
Available hydrographic data for the Catalano-Balearic sea indicate the presence of a ridge-shaped elevation of the isopycnals, forming a front parallel to the Catalan coast, approximately mid-way between the Iberian peninsula and the Balearic islands. This structure appears as a divergence between the southwest-flowing coastal current on the Catalan side and a flow to the northeast on the island side, and is associated with consistent regularities in the biological distributions. Repeated studies of the mesoscale distribution of phytoplankton organisms have shown patterns that may be interpreted in relationship with the presence of the front.

Propriétés gélifiantes des protéines myofibrillaires du poisson (surimi). L'exemple du Tacaud (Trisopterus luscus)
Provedor de dados: 5
Autores: Verrez-bagnis, Veronique; Chopin, Christine; Han Ching, Lucay.
Surimi is a japanese term refering to minced and thoroughly washed fish meat. Quality of surimi is determined by its ability to form a firm and elastic gel after heat treatment. The parameters affecting this property are : fish species, storage before further processing (refrigeration, icing, freezing), addition of cryoprotectors limiting the protein denatura during freeze storage, addition of texturing agent such as starch and egg white. The effects of some of these parameters have been studied on Whiting-pout surimi (Trisoptesus Luscus). Water content of surimi has a great influence on kamaloko quality. Increase ,in starch and egg white concentration does not improve gel quality in terms of rigidity and cohesiveness. A ten day storage of whiting-pout on...

Geochimie et ecologie d'un microenvironnement hydrothermal: Les secretions de mucus de Paralvinella palmiformis
Provedor de dados: 5
Autores: Juniper, Kim.
The geochemical environment at hydrothermal vent openings can be modified by the presence of biological structures and debris. This paper describes how mucus secretions of Paralvinella palmiformis accumulate within faunal aggregations at vents in the northeast Pacific. Mucus is continually secreted and shed by the worm as a means of clearing its epidermis of precipitating inorganic particles. The presence of metallothinonine and large quantities of elemental sulfur in the mucus suggests that it may also function as a carrier of toxins secreted from the interior of the worm. Mucus deposits form a unique physiochemical microenvironment that provides a microhabitat for bacteria and a unique and abundant meiofaunal community.

PCB contamination and i ts relationship wi th suspended particulate matter (SPM) have been studied in water from the Seine estuary and the baie de Seine, in July 1985 and February 1986. PCB chromatograms are very similar and characterize a chronic contamination. PCB concentrations vary from 2 ng/l in the marine zone up to 210 ng/l in the estuary. SPM and PCB concentrations are weIl correlated. Highest PCB concentrations are measured in February due to higher SPM inputs mainly made of finer particles.

The beach of the meteorological station of Europa Island (Indian Ocean S.W.) is a major nesting site for the green turtle. Altimetric distribution of nests on the beach is such than 95 % of nests are laid in the band located between 1.25 and 3 m above the mean level of upper tides. Nest density is a function of adult females number and varies from 0.175 to 0.043 nest/m2 for the two analyzed nesting seasons. Ground temperatures at 60 cm and 100 cm depth range from 22 (winter) to, 30°C (summer). Interannual variability of ground temperature at same depth (incubation depth) is 1.5° C from extreme hot to cold years. These intra and interannual variations are supposed to have an effect upon the sex-ratio of hatchlings

Autores: Bachere, Evelyne; Chagot, Dominique; Grizel, Henri.
There is an ongoing need to isolate and purify ceIls in bivalve mollusc disease research. Many separation techniques differentiate cells solely by a single factor and usually require additives in the medium that may damage live cells. Centrifugai elutriation is a technique that separates particles by size and density simultaneously and can be conducted in physiological media without additives. Living cells can be separated without chemical damage and, because the procedure can be conducted aseptically, cells can be maintained in vitro after elutriation. A description of the technique, methods to determine flow rates and rotor speeds, and a preliminary separation of oyster hyalinocytes is presented

Apparent nutrient consumption and oxygen production, representing net community production, appear among other methods to offer a valuable approach to new production. Net community production determinations were carried out a long time ago in the Mediterranean Sea, with the idea of comparing them with super(14)C-productivity measurements. Our main objective here is to summarize the results of these studies and to review them in relation to the latest discussions concerning productivity of the Sargasso Sea. In the main oligotrophic coastal waters of the Ligurian Sea, there is no evidence for positive net production in the subsurface oxygen maximum associated with the summer thermocline (Minas, Coste, 1964), and Reid's (1962) physical explanation of the...

Near-bottom chlorophyll maxima in southeastern Mediterranean shelf waters: Upwelling and sediments as possible nutrient sources
Provedor de dados: 5
Autores: Townsend, D W; Christensen, J P; Berman, T; Walline, P; Schneller, A; Yentsch, C S.
The level of primary production in the waters overlying the continental shelf of the southeastern Mediterranean, particularly off Israel, is very low, especially since the curtailment of the annual Nile River flood waters following construction of the Aswan High Dam in Egypt. Present sources of inorganic nutrients necessary for primary production include: a) the present Nile discharge and other local terrigenous sources; b) cross-shelf exchanges with the deeper waters offshore; and c) regeneration within the sediments. Ongoing investigations have shown that much of the Israeli shelf resides well within the euphotic zone and that vertical profiles of chlorophyll concentrations usually increase near the bottom.

Modele d'ecosysteme pelagique des eaux cotieres de la Mer Ligure
Provedor de dados: 5
Autores: Andersen, V; Nival, P.
A simplified model of the pelagic ecosystem of the coastal surface waters (0 to 20 m) of the Ligurian Sea (Mediterranean) is described. Phytoplankton, copepods, salps, chaetognaths, dissolved inorganic nitrogen and particulate organic matter are considered. The system is open (winter input of deep nutrients and sedimentation of particulate organic matter) and is influenced by temperature and irradiance. This model simulates the typical annual variation of the plankton in the considered area. Nevertheless, a simulation during five years shows that, in contrast with the other state variables, salps and chaetognaths have an unstable behaviour. We assume that these organisms migrate in the superficial waters.

Surface circulation in the Algerian basin during 1984
Provedor de dados: 5
Autores: Taupier-lesage, I; Millot, C.
The Algerian current observed during most of the summers between 1975 and 1983 appeared as a succession of eddies (diameter about 100 km) propagating eastward along the coast. In 1984, however, satellite infrared imagery revealed two huge (diameter about 200 km) and driftless anticyclonic eddies occupying most of the Algerian basin. The Atlantic water was deflected seaward as far as the Balearic islands by the westernmost eddy located off Algiers, and was then dispatched by other eddies throughout the basin as if by a set of paddle-wheels. Nevertheless, and independent of the general situation, the occurrence of eddies induces secondary phenomena such as advections of surface water from the Liguro-Provencal basin into the Algerian basin, cool tongues and...

Porewater nutrient concentrations and nutrient fluxes between the sediments and overlying waters were determined with cores from an 80 m site on the Israeli shelf. Silicate fluxes predicted from porewater profiles with vertical molecular diffusion were 5.5-fold less than those measured suggesting the occurrence of bioturbation. A two-zoned diagenetic model, including bioturbation and molecular diffusion in the upper 4 cm of sediments but only molecular diffusion below, sedimentation, and a first-order dissolution rate where the rate constant was much greater in the bioturbated zone than at depth, could explain both the near-exponential profile shape and the large measured flux. Burial and denitrification could remove nitrogen at rates as great as 25% of...

Remblaiement de la zone du terminal de la liaison transManche - Effet des dragages et des rejets d'eaux issus des remblais sur la flore, la faune marine et les activités halieutiques
Provedor de dados: 5
Autores: Monbet, Yves; Delpech, Jean-paul.
Le lien fixe transmanche dont la mise en service est prévue pour l'année 1993 nécessite la construction de deux terminaux, l'un situé en Grande-Bretagne et le second en France comportant notamment des voies d'accès, des aires d'accueil, des quais ainsi que des bâtiments administratifs et des ateliers d'entretien (figure 1). De côté français, les ouvrages du terminal se répartiront sur une surface approximative de 50 ha et seront composés essentiellement par six grandes zones (figure 2) : - accès routiers et échangeurs, - terminal tourisme, - terminal commercial, - quais, - zone de maintenance, - boucle ferroviaire. Compte tenu de la géomorphologie des terrains en place, la réalisation de ces zones d'activités nécessite d'importants mouvements de terrains....

Modeling mud transport in a macrotidal estuary
Provedor de dados: 5
Autores: Le Hir, Pierre; Bassoullet, Philippe; L'Yavanc, Jacky.
In order to determine the fate of the fine particles and adsorbed contaminants in a short macrotidal estuary, a mathematical modelling system for cohesive suspended mater transport and bottom evolution, including a new consolidation algorithm, is developed. An analysis of successive erosion, transport and deposition processes due to tidal forcing is given and comparisons with field data are provided. A description of mean-terrn bottom variations has been attempted and is partially validated by differential sounding.

Bilan des perturbations phytoplanctoniques observées sur les côtes françaises en 1985
Provedor de dados: 5
Autores: Berthome, Jean-paul; Belin, Catherine.
In 1985, twenty discolored waters have been observed with dinoflagellates as the most frequently encountered group. Shellfishes mortalities due to occurence of Gyrodinium spirale were observed in Etang de Thau. Likewise, the growth of molluscs juveniles was inhibited by a bloom of Gyrodinium aureolum (Tinduff area). At last, development of Dinophysis cf. acuminata in some coastal areas has caused provisional prohibition of shellfishes selling. However, economic consequences were less important than in 1984 and particularly with regard to 1983.

Peuplements de carnivores planctoniques gelatineux et structures productives en Mediterranee occidentale
Provedor de dados: 5
Autores: Dallot, S; Goy, J; Carre, C.
Planktonic carnivores (chaetognaths, ctenophores, medusae and siphonophores) collected in the upper 200 metres of the Ibero-Moroccan bay and the western Mediterranean were used to obtain a classification of stations in terms of distinct faunistic zones. The planktonic community of the central sector of the Mediterranean shows a progressive devolution of abundance with the gradual disappearance of meroplanktonic and budding species and the increase of oceanic forms (Sagitta bipunctata, Eudoxoides spiralis and Rhopalonema velatum ). These faunistic zones of the Mediterranean, from the Strait of Gibraltar to the Ligurian Sea, can therefore be interpreted in terms of succession, from an initial state of maximal diversity and abundance caused by the mixing of...

Essais de prégrossissement de l'huître plate (Ostrea edulis) à partir de naissain capté en Méditerranée
Provedor de dados: 5
Autores: Dupuy, Blandine.
La maîtrise du prégrossissement d'huîtres plates s'avère indispensable pour valoriser sur le littoral Languedocien le naissain capté en mer ouverte. Cet essai effectue la comparaison de trois sites : - en mer ouverte à - 20 mètres à Gruissan sur une concession mytilicole. - en étang à proximité d'une zone d'élevage de palourdes à Port-la-Nouvelle. - en bassin aménagé pour l'élevage de crevettes dans les marais de Campignol. A partir de naissain de 0,5 cm en mai-juin, on a obtenu des jeunes huîtres de 2 à 6 cm en octobre. Le suivi du milieu (température, salinité, chlorophylle a) aide à comprendre l'évolution de l'élevage pendant la période de prégrossissement. L'importance de la qualité du naissain de départ est mise en évidence.

Biochemical composition and energy value of Crassostrea gigas (Thunberg) cultured in the bay of Marennes-Oleron
Provedor de dados: 5
Autores: Deslous-paoli, Jean-marc; Heral, Maurice.
In the bay of Marennes-Oleron the dry flesh of Crassostrea gigas ranged from 29 to 52% proteins, 10 to 23% ash, 6 to 20% lipids and 0 to 4% carbohydrates of which 48.3 ± 21.6% were glycogen. The energy value ranged from 18.84 to 23.47 joule. Mg(-1) ash free dry weight (mean 20.27 J. mg(-1). Reproductive effort varied from 17.8 to 55.9% dry weight for males, and 43.1 to 61.9% for females during the first and third year of reproduction respectively. A high energy value for female gametes (23.47 to 26.24 J. mg(-1) dry tissue) was mainly due to a higher level of lipids (17.3 to 23% of dry tissue) in female gametes as compared to that in male gametes (5.9 to 12.3% of dry tissue). During the period of mass-loss which began in October and finished in March, the...

Initiation a l'anthropologie economique : resume de cours
Provedor de dados: 5
Autores: Weber, Jacques.
The economic anthropology course proposes to examine notions or facts whose supposed "evidence" leads them to be studied closely, from a point of view very unfamiliar to economists or statisticians. The problems of defining "household" in places where there are varied forms of family organisation illustrates the need for "qualification" of the quantitative data before implementing economic and statistical methods. So that we can come right to the nature of the questions for which the anthropological approach can improve the economic approach, we will examine a series of examples in order to introduce the course's foundations. The examples chosen concern the problems of metrics (1); to the gap that can separate country logic from the rationality of...

Autores: Bertrand, Jacques.
Avec le doublement de l'effectif des chalutiers entre 1984 et 1987, la flottille des navires de pêche industrielle de Saint-Pierre et Miquelon est actuellement composée de six unités, cinq chalutiers de pêche fraîche et un congélateur. Les analyses conduites sur les données de 1986 ont montré que cette flottille était très homogène tant en référence aux caractéristiques techniques et à la pui ssance de pêche des navires qu'en terme de stratégie d'exploitation (zones de pêche, espèces recherchées). Après une diminution jusqu'à 4500 tonnes au début des années soixante-dix, les captures de la flottille industrielle de Saint-Pierre et Miquelon ont augmenté régulièrement jusqu'à atteindre 23 000 tonnes en 1986 et en 1987. Cette évolution est marquée par...

Autores: Bianchi,.
All samples of water collected in hydrothermal areas at 13 degree N should viable bacteria. Most of the heterotrophic bacteria were aerobic and mesophilic. Thermophilic bacteria were the least numerous, even in vent water. Among anaerobes, sulphate reducing bacteria were present, of which few were thermophilic. No methane-producing bacteria were detected in these waters after two months of incubation at 30 degree and at 80 degree C. In the samples studied, no ultra-thermophilic bacteria were found.

La situation zoosanitaire reste inchangée en ce qui concerne l'extension des parasitoses, cependant à l'exception de la Baie de Saint-Brieuc, la virulence de Bonamia ostreae a diminuée et a permis de poursuivre les essais d'élevage à Cancale et de reprendre l'élevage en Baie de Quiberon. Des essais réalisés avec le naissain d'écloserie obtenu à partir d'huîtres ayant résisté à la parasitose montre l'acquisition d'une certaine résistance. Les tests seront poursuivis en 1988 et au cours des Prochaines années. Selon les résultats, l'effort de captage pourra être porté sur les zones où cette résistance pourrait être plus marquée. Les travaux sur les modèles menés en pathologie fondamentale ont permis de mettre en évidence chez Crassostrea gigas un facteur de...

Autores: Perodou, Jean-bernard.
Fishing power analysis leads to determine a typology of fleet which depends on target species. Three factors are examined : port of origin, engine power and type of trawl. Specific abundance index analysis leads to determine a diagram of principal stages of vital cycle : juvenile, reproductive adult and recovery adult. Then calculs are made in value for all species combined : we obtain thus an economical index by location and season.

Autores: Catanzano, Joseph; Gilly, Bernard.
Almost twenty years have passed since the first production tests of salmonids in a marine environment in France (1970) (see VIDAL GIRAUD, 1980). After the laboratory work, joint experiment programmes (fishermen-CNEXO) were developed that ended in the beginnings of production. Conducted during the 70s, the research work and experiments to true scale (SODAB in the Côtes du Nord region and sites at Brest and Cherbourg harbours) opened the way to setting up twenty-odd salmon-farming operations.

[Biostratigraphy and paleoecology of the Neogene micromammalian faunas from the Calatayud-Teruel Basin (Spain) / Freudenthal, M. (editor)]: Cricetidae (Rodentia) from the type Aragonian; the genera Democricetodon, Fahlbuschia, Pseudofahlbuschia nov. gen., and Renzimys
Provedor de dados: 16
Autores: Freudenthal, M.; Daams, R.
This paper deals with four cricetid genera that were formerly assembled under the genus names Democricetodon and Fahlbuschia. Four new species are described, Fahlbuschia decipiens, Fahlbuschia corcolesi, Renzimys lacombai, and Pseudofahlbuschia jordensi gen. nov., sp. nov. The material studied is placed in its stratigraphic context, and appears to be most valuable for a stratigraphic subdivision of the Aragonian. The evolution and paleoecology are discussed.

De mosflora op Iepen en andere bomen in Noord-Groningen
Provedor de dados: 16
Autores: Weeda, E.J.
An inventory has been made of the bryophyles growing as epiphytes on trees in the northern part of the Dutch province of Groningen. Generally speaking, Ulmus x hollandica proved by far the richest tree from a bryological viewpoint, but near the sea-coast sometimes Populus x canadensis and Fraxinus excelsior may be fairly rich (table 1). Eight species were found that in a wider context can be termed more or less rare, viz. Frullania dilatata, Leucodon sciuroides, Orthotrichum lyellii, Radula complanata, Tortula laevipila, T. papulosa, Ulota phyllantha, and Zygodon viridissimus. Most of them are strongly declining, at least in other parts of the Netherlands. In the investigated area Ulota phyllantha, Frullania dilatata and Orthotrichum lyellii appear to be...

Editorial note: As announced in the previous issue we have here deleted all references to the Algae, Fungi, and Lichens. Except for a few protests, there appears to be little interest in these subjects among Malesian botanists. ‘I am told that Chinese printers have a tradition which obliges them to introduce into their works a sprinkling of intentional errors; the reason for this curious action is to provide the careful reader with that sense of superiority which follows discovery of another man’s typographical lapse. We all know that strange pleasure; and while I would not rob you of such harmless delight it is nevertheless my sincere hope that no one will leave this Bibliography ... with a violent attack of superiority complex.’ (J.

Autores: Jong, K.M. de; Coomans, H.E.
The present study is based on the well-known publication “Caribbean Seashells” by Warmke &amp; Abbott (1961); its data are not repeated here, but a large number of mainly small species were added. Most data from “Gegevens over Mariene Gastropoden van Curaçao” by De Jong &amp; Kristensen (1965) have been included. Furthermore most of the photos of species in “A survey of the littoral Gastropoda of the Netherlands Antilles and other Caribbean Islands” by Coomans (1958) are reproduced. The figures of species treated by us and occurring in “Caribbean Seashells”, in “The Western Atlantic Marine Mollusks, described by C. B. Adams” by Clench &amp; Turner (1950) or in “American Seashells” by Abbott (1974) are referred to.

Character analyses for discrimination and affinity recognition of the North American Microlepidoptera in the genus Ectoedemia Busck (Nepticulidae: Lepidoptera)
Provedor de dados: 16
Autores: Wilkinson, Christopher.
Character analyses have been carried out on the North American species in the genus Ectoedemia Busck in order to obtain a measure of their phenetic affinities. The characters used (140) were not only morphological but ranged widely through aspects of biology, and led to the production of up-dated descriptions. Diagnoses based on, and interpreted through, the numerical results are also given. The most important results from seven cluster analyses and principal co-ordinates analyses with minimum spanning trees, contouring, nearest neighbours and similarity coefficients are discussed.

Review
Provedor de dados: 16
Autores: Leenhouts, P.W.
The Flora of Australia started in 1981 and since then 8 volumes came out, including some 70 families. Before all we have to congratulate the editors with this achievement and we express our hope that it will be possible to go on like this. Eight volumes provide the possibility for a more general evaluation. First of all, just turning over the leaves of these volumes, one is struck by the balanced design, the clear typography, the amount of illustrations. However, on further consideration one feels some disappointment. Only once in a hundred years a Flora of Australia appears to be written, and accordingly it should be as good as possible. It is a pity then if you find too often mistakes, often unnecessary ones, and inaccuracies.

A preliminary review is presented of fish species having consumed pelagic Cnidaria (Scyphozoa and Hydrozoa) as well as Ctenophora. Quantitative data are scarce. Knowledge of morphological and physiological adaptations of fishes foraging on gelatinous plankton is almost non-existent. Many fish species consume medusae and some reasons to suspect that there are even more that do so, are discussed.

Ledermann’s and some other German localities in Papua New Guinea

Collecting localities are of special interest to those who want to know the exact origin of the material under study: e.g. when citing types, designating neotypes, preparing distribution maps, planning expeditions, comparing species lists, or because of some historical interest. It is not always easy to gather these data, especially in the case of many former colonies where geographical names as used on collections have been changed (or may never have been recorded by the authorities and include on maps or in official gazetteers). As we have spent some time to gather the present information, we thought a wider audience might be interested. For a brief period, 1884 to 1921, the northern half of Papua New Guinea was a German colony, and the mainland portion...

De standplaats van Addertong (Ophioglossum vulgatum L.) in de Zevensprong bij Craubeek
Provedor de dados: 16
Autores: Sykora, K.V.; Bokeloh, D.; Boer, A. de.
The authors describe the syntaxonomy and synecology of the vegetation of a locality near Craubeek in which Ophioglossum vulgatum was found in 1988. Since 1950 the species has been found in Zuid-Limburg on seven localities. In general it occurs in wet or moist grasslands, but near Craubeek it occurs in a rather dry Arrhenatheretum elatioris picridetosum which is rather unusual. This syntaxon consists of subruderal meadows on moderately dry soils. Other main phytosociological elements in this community are the Mesobromion, the Origanetalia and the Artemisietea.

Note on the floral development of Thottea (Aristolochiaceae)
Provedor de dados: 16
Autores: Leins, P.; Erbar, C.; Heel, W.A. van.
The occurrence of four placentae is a constant character in Thottea. The species can be distinguished by differences in the androecium. The androecial pattern is relatively variable and its rather high plasticity in the genus is suggested to be a derived feature within the family. The gynoecial structure is most remarkable, as the stylar organs do not correspond with the placentae in number nor in position. It is assumed that these organs do not belong to the gynoecium morphologically. They may represent independent, phylogenetically secondary organs, which may function in the capturing of pollen.

There exist three different kinds of leaf arrangement in neotropical species of Rinorea. 1. an alternate leaf arrangement consisting of only laminar leaves; 2. an alternate leaf arrangement consisting of laminar leaves in the apical part of the branchlets and scale-like ones subpersistent in the basal part; 3. an apparently opposite leaf arrangement consisting of laminar leaves together with a pair of inconspicuous and soon deciduous scale-like leaves at the base of the inflorescences. In this article hypotheses have been constructed how one kind of leaf arrangement can be derived from the other, how these three different kinds of leaf arrangements can be correlated with the arrangements of the inflorescences and those of the branchlets, and finally how an...

The biogeography of the holarctic Nephrotoma dorsalis species-group (Diptera, Tipulidae)
Provedor de dados: 16
Autores: Tangelder, Ida R.M.
A biogeographic analysis is presented for the Holarctic Nephrotoma dorsalis-group in relation to the palaeogeographic, climatic and floristic history of the Holarctic region in the Cenozoic. Holarctic intercontinental connections across the Atlantic and by way of Beringia are discussed as well as the biogeographic developments in both the Palaearctic and Nearctic regions. Much attention is paid to a comparison with other insect groups. It is concluded that the history of the dorsalis-group was enacted largely in the Tertiary, besides Pleistocene influences on diversity and distribution. The early Tertiary origin of the group is located in the eastern Palaearctic, and its members are supposed to have reached Europe not prior to the late Miocene. It is...

Review of the South American characiform fish genus Chilodus, with description of a new species, C. gracilis (Pisces, Characiformes, Chilodontidae)
Provedor de dados: 16
Autores: Isbrücker, I.J.H.; Nijssen, H.
Examination of 291 specimens of Chilodus, a genus of South American fresh water fishes, yielded the presence of three species, viz.: C. punctatus, C. zunevei, and C. gracilis. Of the first species the lectotype is designated. The type material of C. zunevei is lost; new material enabled a redescription of this species. C. gracilis is described as a new species, although it is known as an aquarium fish since decades. The three species are illustrated; a key to them and a map showing their distribution are included.

Talitridae (Crustacea – Amphipoda) of the Korean coasts
Provedor de dados: 16
Autores: Yo, Young Won.
Four species of the Talitridae, Trinorchestia longiramus n.sp., Platorchestia crassicornis (Derzhavin, 1937), P. munmui n.sp., and P. pachypus (Derzhavin, 1937) are described from the sandy or gravelly coasts of Korea, and their distribution is mapped. The taxonomic distinction between two confused species P. crassicornis and P. platensis (Kreyer, 1845) is restudied by comparison with material from northwestern Pacific and Atlantic coasts, some significant characters of the latter are illustrated, and the doubtful distribution of the latter in the Indo-Pacific region is discussed to some extent. A scanning electron microscope study reveals that the microstructure of the retinacula might be useful for the taxonomy of the group.

Editorial The first 150 years of “Artis” and the Artis Library
Provedor de dados: 16
Autores: NN.
This year, 1988, the Royal Zoological Society “Natura Artis Magistra” (usually abbreviated to “Artis”) is celebrating its 150th anniversary. During all the festivities, hardly any attention has been paid to the fact that its library was also founded in 1838. In order to rectify this, this editorial briefly reviews the history of the Artis Library and its superb collection. It is known that from the very beginning books were donated to the Society; for instance a complete Buffon edition was acquired in the first year of the Society’s existence. Very little has been published on the early history of the Society’s library, although much relevant information can be found in the “Artis” archives (now deposited in the Amsterdam municipal archives).

The Pahang and Johore State Governments have agreed to declare the 92,000 hectare Endau-Rompin Forest as a State Park. It had been proposed as a National Park in 1975, but, as usual, this did not prevent logging in the core area in 1977. This was halted after considerable national protest, but logging still occurs around the fringes and between S. Kinchin and S. Kemapan. The area is not only important for its animals (largest breeding population of Sumatran rhinoceros), but also has an outstanding botanical significance (see also articles on the Malaysian Heritage and Scientific Expedition to the area by e.g. B.H. and R.

Autores: Corporaal, A.; Bruin, C.J.W.
Carex. x tornabenii (C. distans x extensa) was recorded for the first time in the Netherlands, on the island of Texel, in 1985. The single specimen grows between the parents in a nature reserve in the dunes in which North Sea water freely goes in and out. In that area, formerly saline or brackish, recently a rather strong influence of sweet seepage water has been observed; this environmental change may have favoured the occurrence of the hybrid. It is remarked that the flowering period of C. distans and C. extensa shows a greater overlap than usually assumed.

A new record of the North American spionid polychaete Marenzelleria viridis (Verril, 1873) is reported from the Ems Estuary. The species was first found in 1983. From 1983 to 1986 densities increased to a few thousands per m2 while densities of another polychaete, Nereis diversicolor decreased. Juveniles showed peak densities of c. 19000 m2 in muddy sediments. Adults preferred sandy sediments. In Europe M. viridis was recorded recently also in other estuaries: Tay and Forth (Scotland), Weser and Elbe (Fed. Rep. of Germany). There is no reliable clue to the cause of its appearance in North Sea estuaries.

With the advantage of starting a new volume with this issue, we have decided to make some changes. Technology doesn’t stop and with the modern way of desktop publishing, we thought that we could offer a more pleasing journal by changing the format of the Bulletin, its lay-out, and various other minor points. Among the more drastic changes is the deletion of the chapters on the Algae and the Fungi &amp; Lichens in the Bibliography, as we threatened to do in the last issue. Very few protests were received on our announcement to do this, so apparently there was no need to laboriously discover (not being specialists in these subjects) whether a certain taxon belongs to the Malesian flora or not.

Autores: Nooteboom, H.P.
This excellent and useful book is based on the early editions of J.C. Willis’s ‘Dictionary of the flowering plants and ferns’. Those early works have been called ‘the most remarkable botanical works of reference ever written – true vademecums for every botanists’s pocket’ (Prof. P.W. Richards). The last edition dates as far back as 1931. After that time the late Dr. Airy Shaw changed the format drastically in making a catalogue which is very useful in its own and ornates nearly every botanist‘s desk. But most of the general information had to be deleted. The omitted data were gathered again and updated by F. N. Howes of Kew, but because of his untimely death the book was not published. It is Dr. Mabberley’s merit to have taken up the task again and even to...

Growth in larval and metamorphosed Eurypharynx pelecanoides Vaillant, 1882 (Pisces, Anguilliformes, Eurypharyngidae) from the mid North Atlantic

The difference between the larvae of Eurypharynx pelecanoides and Saccopharynx ampullaceus, both belonging to the suborder Saccopharyngoidei (formerly Lyomeri), does not consist only of different numbers in myomeres but also of the structure of the suspensorium of the lower jaw. In E. pelecanoides it consists of two separate bones, the hyomandibulare and the quadratum. According to Orton (1963) in S. ampullaceus the suspensorium consists of only one piece of bone.

On the development of some Gynoecia with septal nectaries
Provedor de dados: 16
Autores: Heel, W.A. van.
Septal nectaries are formed by local regions of later nectariferous epidermal cells on the sides of the carpels at their very base. In order that the epidermal cells may differentiate into nectariferous cells, the carpels which constitute the gynoecium have to develop as separate organs. It was argued that if no septal nectaries develop, this free carpel development does not take place. The nectariferous regions get shaped as nectar containers by dermal fusion of the sides of the carpels surrounding them, by upward growth of the apex, and mostly also by meristematic continuity of part of the ovary wall on the outside. By the latter the level of the openings of the nectaries on the ovary is defined. Septal nectaries in Monocotyledons are considered original.

Autores: Broodbakker, Nico W.
This project was originally planned to take place in the summer of 1985. Due to unforeseen circumstances it could not in fact be carried out until the autumn of 1986. This meant that some aspects of the project had to be changed because of seasonal influences. One major drawback was the absence of any flooded rice fields, because the fieldwork was done after the growing and harvesting of the rice. It was therefore impossible to collect any ostracods from ricefields in south west Honshu. Since the rice fields are one of the major ostracod habitats in Japan, this meant a dramatic decrease of the number of possible collecting sites.

In absence of complete descriptions of M. minutus, especially concerning absolute measurements, these are completed with observations on a West-German population. The other species, called Metacyclops mutatus n. sp., may have evolved from mendocinus-like ancestors, but differs obviously in comparison with the morphologically similar species M. aequatorialis Dussart, 1977 and M. chelazzi Dumont, 1981.

The Index Kewensis seems too well known for more than an announcement. On the other hand, however, it is of so great practical value to the plant taxonomist that even the slightest change may be distinctly practical or not. And thanks to the use made of the computer there are some changes this time. The most important one, distinctly for the better, is the fact that whereas Supplement 17 still came out with the about normal time lapse of seven years, Supplement 18 was published only about 1½ year after the closing date. The yearly Kew Index, the first issue of which is also announced here, will even reduce this lapse to less than one year! Furthermore, from 1986 on in the Kew Index, and accordingly in the Index Kewensis, the Ferns and Fern allies will also...

In 1986 a population of Matteuccia struthiopteris was found in a planted Populus-wood in the polder Oostelijk Flevoland, growing on calcareous, sandy soil which was wet because of considerable amounts of seepage water. The habitat fits well with natural habitats of the species in Central Europe. As, moreover, quite a number of bryophytes, fungi, and pteridophytes from seepage habitats have recently been found in the vicinity, the new Matteuccia locality may be considered as a natural one.

Problems in the organization of plant taxonomic work
Provedor de dados: 16
Autores: Ng, F.S.P.
The final volume of the four-volume Tree Flora of Malaya is just being completed in 1987. This project has taken 22 years, for an area that is geographically small and floristically relatively well-known. This paper is concerned with the slow rate of taxonomic progress in the tropics which makes taxonomic projects increasingly difficult to promote and organize. It is suggested that the problems may be overcome by demystifying taxonomy. This involves acknowledging that a significant component of taxonomic decisions are subjective, egoistic and arbitrary, that no taxonomic decision or treatment can ever be final, that the principle of one correct name per species is not always tenable, and that stability in scientific nomenclature is unattainable. — Paper...

The genus Orophea Blume (Annonaceae: Saccopetaleae) has been revised with the following main results: — The genus in the circumscription of most authors is not monophyletic, but biphyletic. The genus Mezzettiopsis Ridley has to be reinstated. — Pseuduvaria, Mitrephora, Petalolophus, Oreomitra, Schefferomitra, Goniothalmus, Exellia, Popowia, Richella, Phaeanthus, Trivalvaria and Atopostema are not closely related to Orophea as supposed by Fries (1959). — For the tribe in which Orophea has to be placed, the name Saccopetaleae Hook. f. &amp; Thomson has to be accepted for nomenclatural reasons. Its members are Miliusa, Orophea, Mezzettiopsis, Phoenicanthus, Alphonsea and Platymitra. — Characters of the genus have been studied and a new classification below...

A revision of Alectryon (Sapindaceae) in Malesia
Provedor de dados: 16
Autores: Leenhouts, P.W.
The genus Alectryon occurs with some 30 species in E. Malesia, Australia, New Zealand, New Caledonia, the New Hebrides, the Solomon Islands, Fiji, Samoa, and the Sandwich Islands. Radlkofer (in Engl., Pflanzenr. 98, 1933: 983-1002) divided the genus into six sections. As a whole these sections are mostly well recognisable, but a clear demarcation between at least some of them appears impossible. Preference is given here to a division into three or four subgenera, which seems more justified. As Mr. George K. Linney, Honolulu, is working on the Pacific representatives of this genus and as Ms. S.T. Reynolds, Brisbane, recently completed a revision of the Australian species, I restricted myself in the present paper to the Malesian taxa.

This book reports on one of the symposia of the Third ICSEB Congress at Brighton, 1985. It is published only six years after the first volume in the same series (“Wallace’s Line and plate tectonics” also edited by Whitmore) treated the same problems for the same region. This is explained by the “important geological discoveries and new paleobotanical evidence” that have come available in the mean time. These discoveries are discussed in Audley-Charles’s contribution where it is stated that present-day Burma, Thailand, Malaya and Sumatra contain fragments rifted northwards from the N. Australian-New Guinea content in the Mesozoic. Being above sea-level in late Mesozoic and later they may have transported early Angiosperms. Although it may be said that the...

This study of Chthonerpeton indistinctum (Reinhardt &amp; Lütken, 1861) considers 25 morphometric characters, teeth-counts and sex, based on 96 specimens. A multivariate analysis of characters and comparisons of geographically arranged samples is carried out by graphic and statistical methods. No trends in geographical variation were found. Subsequently a redescription of the species is presented, including measurements and counts. Sexual dimorphism was observed for four characters related to the cloacal region. The results are discussed and compared with previous reports. Character-variation is also studied. Primary annuli counts show very low variation; sample variation profiles were similar for the remaining characters. A revision of biological data...

Tetrapocillon atlanticus n.sp. (Porifera, Poecilosclerida) from the Cape Verde Islands
Provedor de dados: 16
Autores: Soest, R.W.M. van.
A representative of the rare genus Tetrapocillon Brondsted (1924) was found for the first time in the Atlantic Ocean, dredged at 70 m depth during the recent CANCAP VII Expedition to the Cape Verde Islands. The single specimen differed from the previously known Indo-Pacific specimens of the genus ( T. novaezealandiae Brondsted, 1924) in the life colour, the possession of thin strongyles (in stead of thicker styles) and the smaller size of the tetrapocilli. For these reasons and the geographic disjunction the Cape Verde specimen was assigned to a new species, T. atlanticus n.sp. The affinities of the genus Tetrapocillon and other genera, seemingly related on the basis of similarities in the microsclere complement are discussed; it is made apparent that it...

Species richness and origin of the bryophyte flora of the Colombian Andes
Provedor de dados: 16
Autores: Gradstein, S.R.; Reenen, G.B.A. van; Griffin, D.
Based on data from the ECOANDES project, a phytogeographical analysis has been made of the bryophyte flora along the wet, foggy western slope (1000-4500 m) and the drier eastern slope (500-4500 m) of the Colombian Central Cordillera at the ‘Parque de los Nevados’. Species richness increases with altitude to the upper montane forest, which holds the largest diversity. Liverworts outnumber mosses in the upper submontane and montane forests on the western slope, but elsewhere, in drier environments, their number is lower and falls to below that of mosses. Furthermore, it appears that at lower altitudes, below 3000 m, wide-ranging tropical species prevail whereas narrowranging tropical species (andean and endemic element) and species of temperate origin are...

Fossil and recent shallow water corals from the Atlantic Islands off Western Africa CANCAP-contribution no. 56
Provedor de dados: 16
Autores: Boekschoten, G.J.; Borel Best, M.
Miocene hermatypic corals are listed from Madeira and Porto Santo. Pleistocene and recent shallow water corals are described from the Cape Verde archipelago. The Miocene fauna was part of the Western Tethyan reef association, which went nearly completely extinct by the development of a cool water current in late Miocene times. The Cape Verde fauna immigrated from the Carribean, presumably by way of a compressed subtropical gyre during a mid Pleistocene glacial phase. The fauna was found in a beach terrace, formerly considered Tertiary, on the island of São Tiago. A lava flow directly above this deposit was radiometrically dated 700.000 ± 200.000 years B.P.

Phylogenetic relationships and biogeography of the groundwater-dwelling amphipod genus Pseudoniphargus (Crustacea), with emphasis on the Iberian species
Provedor de dados: 16
Autores: Notenboom, Jos.
Numerical phylogenetic methods are applied in order to arrive at synapomorphic similarities between species of the stygobiont amphipod genus Pseudoniphargus. Character polarity is assessed by comparison with the relevant outgroups Parapseudoniphargus and Allomelita, within a cluster of presumedly interrelated genera of Hadzioidea. The degree of morphological differentiation of Pseudoniphargus is low and the available potential apomorphies are insufficient to resolve phylogenetic relationships to the species level. The inconsistency in the data is high, which may be a result of an underlying peripatric speciation model, difficulties in discriminating mutual exclusive and homologous character states, and a high probability of independent character evolution....

Some data on Milaculum Müller, 1973
Provedor de dados: 16
Autores: Boogaard, M. van den.
An investigation of some faunas rich in Milaculum Müller, 1973 lead to the conclusion that the Milaculum animal was - at least partly - covered by plates of different morphology. Several specimens of Milaculum were encountered with adhering smaller platelets showing that the epidermal tissue of this animal consisted of a mosaic of larger and smaller plates. The characteristics of the material encountered are suggestive of an agnathan affinity of Milaculum. Two new species are described, Milaculum balticum from the Upper Ordovician of Estonia and M. longmyndium from the Lower Silurian of the Welsh Borderland.

De verspreidingsgrens van de Ruige leeuwetand (Leontodon hispidus L.) in Nederland en zijn voorkomen op veen in de Krimpenerwaard
Provedor de dados: 16
Autores: Weeda, E.J.
The limits of the distribution of Leontodon hispidus in the Dutch riverine area are difficult to be established because the species is often confused with L. saxatilis. Generally the former species occurs in rather dry grassland on chalk, loess or river clay. During an investigation of marginal parts of its area, L. hispidus was found to thrive on peat in a road verge in the Krimpenerwaard (IVON-square 38.23). A ‘relevé’ of this locality is given. In contrast with several recent records, along the lower course of the Gelderse IJssel the author observed only L. saxatilis and no L. hispidus. A former (apparent?) gap in the species’ distribution in the western part of Noord-Brabant has been filled up for the greater part. On the other hand, L. hispidus has...

Genetic differentiation of the Iberian amphiodus Gammarus ibericus Margalef, 1951 and G. gauthieri S. Karaman, 1935, with reference to some related species in France
Provedor de dados: 16
Autores: Scheepmaker, Maarten; Meer, Frits van der; Pinkster, Sjouk.
Populations of five related species belonging to the Gammarus pulex group from the Iberian Peninsula and southern France have been studied electrophoretically at 21 enzyme loci. Morphologically distinct forms from the same side of the Pyrenees proved to be genetically more similar than morphologically very similar forms from opposite sides of this barrier. With reference to published data, genetic differentiation between French and Iberian species was observed at the generic level. Inter-areal intraspecific genetic differentiation in Iberian species may warrant recognition of subspecies or sibling species. However, cross-breeding experiments performed did not assess levels of reproductive isolation of the forms involved. A dendrogram derived from genetic...

Sexual dimorphism in aegisthid cephalosomic appendages (Copepoda, Harpacticoida): a reappraisal

Autores: Huys, Rony.
The cephalosomic appendages, including the rostrum, are redescribed in the bathypelagic harpacticoid Aegisthus mucronatus Giesbrecht, 1891 (Aegisthidae). Profound sexual dimorphism was found in all cephalosomic appendages. For the first time reference is made to the presence of a mandible in the male and figures are given for the male maxillula. Distinct sexual differences are also observed in the structure of the labrum and the labium. The structure and ornamentation of the male antennula clearly shows that the Aegisthidae belong to the monophyletic group Cervinioidea, including also the Rotundiclipeidae and Cerviniidae. Brief comments are made on the nature of the first pedigerous somite, the structure of the anal somite and of the caudal rami. The...

This North American/East Asian taxon has been sown on a road verge in Leiden as a component of a commercial mixture of grass seeds from so-called ‘wild species’. It is likely that it will have been sown elsewhere in the Netherlands, too. After having been deliberately introduced in North America, subsp. inermis appeared to hybridize spontaneously with native subsp. pumpellianus. Thus it is not unlikely that the reverse situation is to be expected in Europe.

Trichoptera hydroptilidae (Insecta) from Soviet Union Far-Eastern territories
Provedor de dados: 16
Autores: Botosaneanu, L.; Levanidova, I.M.
This is a contribution to the study of the scarcely known Trichoptera Hydroptilidae from Soviet Far-East (Primorye, Amur River basin, Kuril Islands, Kamtschatka, Chukotka). The discovery of a new species of Stactobia McL. on Kunashir Island, very far from the known distribution area of the genus, was quite unexpected. Agraylea multipunctata Curt., 1834, and A. cognatella McL., 1880, certainly are distinct species, both present in the Soviet Far-East, but apparently not sympatrically. Oxyethira ecornuta Morton, 1893, previously known from Fennoscandia and from eastern Canada, is redescribed from Primorye. Orthotrichia tragetti Mosely, 1830, with eastern-most known localities in Ukraina and Finland, is another surprising discovery for Primorye.

Les larves d’Ecnomus tenellus et d’E. deceptor (Trichoptera, Ecnomidae): identification, distribution, biologie et écologie
Provedor de dados: 16
Autores: Stroot, Philippe; Tachet, Henri; Dolédec, Sylvain.
The larva of Ecnomus deceptor is described for the first time and compared with that of E. tenellus, from which it differs by coloration patterns and dimensions. The larvae of both species are otherwise very similar in their morphology and ecology. Both are predators and rather tolerant towards environmental conditions. Therefore, questions arise concerning the relatively limited distribution of E. deceptor, as well as possible competition between Ecnomidae and Polycentropodidae and between sympatric populations of Ecnomus.

Onverwacht ontvingen wij het bericht dat drs. J. Mennema per 1 augustus a.s. het Rijksherbarium verlaat wegens zijn aanstelling als stadsecoloog bij de gemeente Den Haag. Jaap Mennema werd in 1965 bij het Rijksherbarium aangesteld; vanaf 1966 maakte hij deel uit van de redactie van Gorteria. Het inventarisatieonderzoek van de flora werd door hem sterk gestimuleerd. Zijn grootste verdienste is ongetwijfeld gelegen in het project Atlas van de Nederlandse Flora, waarvoor hij aanzienlijke subsidies wist te verkrijgen, en dat onder zijn leiding vrijwel voltooid werd.

Het Hafdistrict als floradistrict
Provedor de dados: 16
Autores: Duistermaat, H.
The floristic composition is studied of the so-called ‘Haf-district’, a region roughly comprising the soils below sea level. The delimitation of this ‘plant-geographical’ region as distinguished by Van Soest (1929) strongly coincides with certain parts of the physical geographical classification by Hof (1983). It is argued here that the term ‘plant-geographical district’ should be changed into ‘floristic district’. The floristic composition of the sea clay soils in the southwestern estuarine region of the country has more resemblance with that of the classical Haf-district than with that of the riverine (‘Fluviatiele’) district. In all, 48 species are typical for the redefined ‘Haf-district’.

Nineteen species of Alcyoniidae formerly assigned to various genera are here placed in the genera Bellonella and Eleutherobia; three new species are described in Bellonella. Sixteen species characterized by an abundance of capstans among their sclerites, formerly assigned to Alcyonium, Bellonella and Nidalia are now transferred as valid species or synonyms to the genus Eleutherobia, in which two new species are described making a total of 14 valid species. A new genus Inflatocalyx is established for a digitiform subantarctic species having only very few sclerites, in the form of nearly smooth spindles, and polyps retractile within large, inflated calyces. Six species comprising the genus Cactogorgia are transferred to Nidalia, and three new species are...

Collection of Groundwater and Freshwater Fauna on the Islands of the South Pacific. Operation Raleigh -- Pacific Crossing
Provedor de dados: 16
Autores: Broodbakker, Nico W.
During this project about 150 groundwater habitats were sampled on a number of islands in the South Pacific. The main habitats sampled were: wells, springs, caves, beaches and streams. Groundwater fauna was only found on two islands. On Easter Island we found a new species belonging to the Isopoda (Crustacea), living in marine groundwater interstitia. On Tongatapu a new species of groundwater Amphipoda (Crustacea) was found in Anahulu Cave. Fragments which possibly belong to the same species were found in some wells on the island. Many samples have not yet been sorted out. Therefore it is possible that more groundwater species will be found, particularly in the beach samples from the Cook Islands, and in the spring, cave, well, and beach samples of the...

Revisión de los Sciuridae del Aragoniense y del Rambliense en la fosa de Calatayud-Montalbán = Revision of Aragonian and Ramblian Sciuridae in the Calatayud-Montalban Trench
Provedor de dados: 16
Autores: Cuenca Bescós, G.
The Sciuridae are the family of rodents that comprises all extant and fossil squirrels. In the Ramblian and especially in the Aragonian of the Tertiary basin of Calatayud-Montalbán (Aragón, Spain) the remains of Sciuridae are relatively abundant. A major problem solved in this paper is the distinction of Ml and M2, both in the upper and the lower dentition. Traditionally, in the literature these elements are treated as a unit Ml,2. We managed to separate them, on the basis of the study of material of two extant species, Atlantoxerus getulus and Sciurus vulgaris. In our study of the fossil Sciuridae from the Calatayud-Montalbán Basin 9 species were recognized, belonging to 6 genera: Heteroxerus rubricati, H. grivensis, Atlantoxerus idubedensis sp. nov., A....

The genital fields of Canuella Perplexa and C. Furcigera (Copepoda, Harpacticoida) – comparative morphology and functional aspects
Provedor de dados: 16
Autores: Glatzel, Thomas.
The harpacticoids Canuella perplexa T. &amp; A. Scott, 1893 and Canuella furcigera Sars, 1903 differ not only in size and length of the furca, but above all in the structure of the genital fields in both sexes. These differences, which have not been described exactly so far, are demonstrated by SEM micrographs and by drawings. Since there is no adequate terminology for the description of genital fields, terms are introduced in this study. A partly extruded spermatophore in a male specimen of Canuella perplexa is shown by a SEM micrograph. Mating has never been observed in either species; however, from the anatomical structure some conclusions may be drawn on the possible configuration of the genital fields during mating.

Autores: Logan, A.
Recent brachiopods collected by CANCAP IV and VI expeditions to the south-east North Atlantic, in the vicinity of the Canary and Cape Verde Islands, belonging to Neocrania, Hispanirhynchia, Stenosarina, Terebratulina, Eucalathis, Argyrotheca, Megathiris, Phaneropora, Megerlia, Kraussina, Dallina, Thecidellina and Pajaudina have been identified. As with the brachiopods previously identified from the CANCAP I-III expeditions, the CANCAP IV and VI material is Mauritanian in affinity and shows a close relationship with Lusitanian brachiopods from the Gulf of Gascogne. There is a lesser affinity with Mediterranean brachiopods, with isolated Senegalian and Caribbean elements present in the Cape Verde Islands.

Autores: Hansen, J.E.
Collete and Chao (1975) reviewed the systematic and morphology of the Genus Sarda and relatives ((Tribe Sardini), including into their analysis a few S.sarda from the SW Atlantic. Before that, Demir (1964)dealt with the meristic data of the same species from the Black Sea. This paper in concerned with the featuring of the bonito caught in Argentina, from both a morphometric and a meristic point of view. The study made the differences reported by Collette and Chao (op.cit.)among W and E S.sarda populations to be more conspicuous, because our samples had even lower values han those from the NW.

Cambios de color en la piel del dorado (Mahi-mahi, Coryphaena hippurus) en relación a la formación de histamina
Provedor de dados: 20
Autores: Wood, C.D.; Camba, N.; Grijalba, M.
En el Ecuador se utiliza el cambio de color en la piel del dorado amarillo a blanco como indicador de la calidad. Se investigó este cambio en relación a la formación de histamina bajo varias condiciones. Luego de este estudio se concluyó que, en combinación a otros parámetros como olor y textura, el color de la piel puede ser útil para distinguir pescado de buena calidad (grado A) y pescado de calidad inferior (grado B). Sin embargo existen condiciones bajo las cuales es posible tener dorado no apto para consumo humano con piel amarilla y por eso siempre es recomendable revisar todas las características sensoriales en la evaluación de calidad. Este cambio de color no hace posible la distinción entre dorado con niveles significativos de histamina. Solamente...

Provedor de dados: 20
Autores: Igbinosun, J.E.; Roberts, O.O.; Amako, D.
The possibility of wholly or partially replaced wheat offals with dried water hyacinth meal in the diets of Tilapia zillii fingerlings was investigated.  Four diets, A, B., C and D were formulated.  Diet A contain 45% wheat offal in addition to fishmeal and soyabean meal as sources of protein.  B and C were diets in which 100% and 50% of the wheat offals were replaced by dried water hyacinth meal respectively.  Diet D had 80% water hyacinth meal and an additional 18% Casein as the only other source protein. Results of four weeks feeding trial showed that Tilapia zillii fingerlings would not ingest diet D containing 80% water hyacinth meal without the addition of fishmeal.  Water hyacinth meal could not wholly replace wheat offals in Tilapia diets unless at...

Previous work has established the technical feasibility of producing acceptable shark-base fish biscuits, which were subsequently used for a school breakfast programme in the poorer areas of Ecuador. However, reformulation of the biscuits using chaeper pelagic fish resources (sardine, mackerel and tuna dark meat) was necessary due to changes in the cost and availability of shark. This paper describes a datailed examination of the organoleptic quality of the pelagic-fish based biscuits, and the results of acceptability test undertaken with children attending 3 schools in the marginal areas of Guayaquil. For the first part, 5 panelists selected from staff at Instituto Nacional de Pesca, rated each of the 3 types of biscuit using 5 rating scale describing...

Autores: Oyewo, E.O.
Laboratory-scale studies on the initial weathering of some oils on water by evaporative loss and dissolution have been carried out.  Evaporation rate was dependent on the type of oil and was accelerated by increased temperature, number retarded evaporation rate.  The order of evaporation rate was Gas Oil &gt;Diesel Oil &gt; Medium fuel Oil.  Dissolution rate, which varied with the type of oil, was retarded by salinity but promoted by increased temperature.  With the mono-component oils tested, the cyclic, aromatic and iso-characters increased dissolution rate. The order of dissolution rate for the commercial oils was Gas Oil   Diesel Oil &gt; Medium Fuel Oil.

The number of purse seiners active in the Western Indian Ocean during the third quarter of 1988 increased from 38 at the end of the second quarter to 43 in July, reaching a maximum of 46 in September.  This represents a considerable increase in the number of active vessels compared to the same period last year when a maximum of 38 vessels were in operation in September. Overall catch rates increased from 19 MT/day during the second quarter of 1988 to 25 MT/day during this quarter, reaching the same level as in the previous year.  The proportion of yellow fin dropped from 53% in July to 17% in September with a corresponding increase in skipjack catches.  This fishing pattern follows the same trend set in previous years, as vessels fished around the Equator...

Autores: Dia, M.A.
L’étude porte sur l’exploitation, la biologie et la dynamique du poulpe (Octopus vulgaris, Cuvier) des eaux mauritaniennes. La répartition spatio-temporelle dans la région du Cap Blanc ne semble être liée ni à la taille, ni au sexe, mais varie au cours de l’année. L’analyse de l’état actuel de la pêcherie basée sur les congélateurs céphalopodiers met en évidence une augmentation de l’effort de pêche et la poursuite de chute des p.u.e. La composition des captures révèle une progression du pourcentage des individus de poids inférieur à 200 grammes (« poulpo »). L’étude biologique montre qu’il existe deux saisons de reproduction par an (mai-juillet et septembre-novembre) qui engendrent deux recrutements, l’un en mai et l’autre à partir de septembre. La...

Commercial catches of the crabe girafe, Ranina ranina in the Seychelles are analyses. Male crabs are dominant in the catch (65_310= male to 35_310= female) Large individuals present in the catch (exceeding 115mm) are all males. The size at first maturity for female crabs is 89.5mm. One spawning season is observed annually, around December Von Bertalanffy growth estimates obtained from length frequency data using the Hasselblad method to separate the modes followed by modal progressions, are as follows: Males: L oo = 160mm, k = 0.24 per year: Females: L oo = 137mm, k = 0.12 per year. Alternative estimates are also given using the Von, Bertalanffy equation assuming seasonally oscillating growth. The total mortality which corresponds to the natural mortality...

Résumé:  Cette étude traite de la biologie et de la dynamique des populations d’anchois (Engraulis encrasicolus) des côtes mauritaniennes. Après un bref rappel des conditions climatiques et hydrobiologiques de la région, une tentative de mise en évidence de race ou population locale a montré que cette espèce pourrait être rattachée à la population méridionale atlantique du Golfe de Gascogne. En  Mauritanie, l’Anchois n’est pêché que de façon accessoire. Les captures les plus abondantes sont réalisées de mai à Septembre essentiellement dans la zone nord où l’on observe un upwelling permanent. Pour évaluer la taille du stock, des estimations de biomasse par échointégration ont été effectuées, mais celles-ci n’ont pas permis de donner un ordre de grandeur...

Cajones con aislamiento térmico para uso de las lanchas de fibra de vidrio del sector artesanal
Provedor de dados: 20
Autores: Wood, C.D.; Grijalva, M.
Se construyeron tres tipos de cajones de madera en su exterior con aislamiento térmico usando materiales que se encuentran disponibles en el Ecuador. El primero fue hecho de madera y polietileno como aislante; el segundo con acero galvanizado en la parte interna, encima del aislamiento de polietileno, y el tercero con fibra de vidrio y resina en el interior, usando como aislante poliuretano. El cajón con fibra de vidrio fue más costoso pero parecía ser el mejor en términos de su peso y resistencia. Se construyeron cuatro cajones más de este estilo con un diseño modificado para pruebas de resistencia más extensas. Se han alcanzado mejoras, pero ese necesario más trabajo para definir diseños de cajones con aislamiento térmico.

Provedor de dados: 20
Autores: Wood, C.D; Boustead, P.; Mora, Y.; Grijalva, M.
En los últimos años han habido evidencias del aumento de exportaciones por vía aérea de pescado fresco. Los desembarques artesanales se destacan en este aumento, particularmente de dorado, y el incremento de las exportaciones estimula también alguna diversificación de productos. Una mayor limitación a más exportaciones se entiende de la competencia para espacio restringible de flete aéreo entre los exportadores de productos perecederos (pescado, flores, frutas, etc.), y de la necesidad de coordinar el reparto y la extensión de la capacidad de carga. Las actividades de pesca y comercialización están muy fragmentadas, y resultó que esta industria compleja era dificil de controlar. Esta es la razón para estudios de este tipo, para actualizar y ampliar la...

Analysis of 450 sediment samples from various rivers in Nigeria have resulted in the identification of seven major drainage systems some of which may be potential sources of heavy mineral contribution to the continental shelf. The seven major drainage systems are: (1) Niger/Benue drainage system with coarse to medium size sediments and a high of 90% opaque mineral concentration in many cases. Some gem heavy minerals like garnet and zircon are also recorded. (2) Gombi drainage system: consists of medium to coarse sand. Opaque mineral concentrations are also high. Up to 90.59% at station BO.99.3. (3) Bauchi Plateau drainage system: Sediments from this drainage system are very coarse and highly angular. This drainage system records the highest overall opaque...

The problem of acid sulfate soils in brackish water aquaculture;
Provedor de dados: 20
Autores: Dublin-Green, C.O.; Ojanuga, A. G.
Actual and potential acid sulfate soils cover over 750,000 ha. of unclassified wetlands in the mangrove swamp of the Niger Delta. This belt serves many functions including aquaculture development.  Presently a number of brackish water aquaculture projects are sited on these soils.  In acid sulfate soils, an acidic condition usually develops due to oxidation of the sulfidic materials (e.g. Iron Sulfides) in the soils. Elements such as iron and aluminum are released to pond water in large quantities, while essential nutrients like phosphorus and nitrogen become fixed in the soil and thus are unavailable to the larger community. Acid sulfate soils pose a range of problems for brackish water aquaculture- including, slow fish growth, low fish yields and mass...

Ce gisement est d’un intérêt économique certain, puisque la biomasse  estimée se situe entre 1,3 et 2,8 millions de tonnes. Après une présentation des résultats obtenus sur les paramètres biologiques essentiels, une approche dynamique de l’étude de la population a été réalisée. Ainsi, en retenant quatre hypothèses de mortalité naturelle, les courbes de rendement par recrue ont été construites. Les productions annuelles potentielles ont pu être calculées sous deux hypothèses d’âge à la première capture et en fixant l’effort de pêche au niveau FO.1. Elles se situeraient en moyenne à 300.000 tonnes, mais avec une forte variabilité liée aux...

The yield of skipjack tuna (Katsuwunus pelamis) was investigated.  It was found that 2,75kg of fresh tuna are required for the production of every 1kg of canned tuna.  Pre-cooking of tuna which is a major processing stage in tuna canning resulted in a loss of about 19% of its weight based on gutted and headed fish.  Changes in the quality of canned tuna packed in brine, oil and tomato sauce at ambient and accelerated temperatures were examined by microbiological and sensory evaluation methods.  Canned tuna samples were found to be microbiologically stable and organoleptically acceptable after one year storage period.  Total viable counts (TVC) were generally low.  Thermophilic organisms, anaerobes (clostridium) and coliforms (E. Coli type 1) were absent in...

Results showed that although all the pellets had Zero Floatation time, it took pellets from the D group longer time to sink.  A and B pellets sank at equal rates.  The crumbling rates on getting to the bottom tended to decrease with decreasing levels of binder. When the diets were later fed to four groups of Tilapia fingerlings for seven weeks, results showed that the growth rate, feed conversion efficiencies and protein efficiency rations followed the trend C&gt; D&gt; B&gt; A.

The concept of technical viability is defined as a combination of factors including fishery resource. Ecology, gear technology, manpower and entrepreneurial skills financial inputs and product markets.  A clear drop in catch per trawler per year in Nigeria is attributed mainly to inadequate cash flow to operate vessels in the face of high fuel costs, lack of spare parts and repair facilities, and some growth over fishing of ground fish stocks.  The transition from artisanal to rapid industrial mechanized fishing has not been matched by the availability of skilled local manpower to effectively operates and service electronic, hydraulic and refrigeration equipment of modern trawlers.  While Nigerian financial institutions have to some extent financed trawler...

At the end of 8 weeks feeding trial the fish increased from their initial body weight of 0.2g, 0.4g, 0.4g and 0.4g to average final weights of 21.2g 15.4g, 12.8g and 13.8g respectively. The diet containing 41.1% resulted in the least food conversion efficiency of 1.2 over the eight weeks period.  Of the experimental treatments the diets containing the highest level of fish silage (41.0%) performed better than any of the other two treatments of 19.0% and 33.5% fish silage contents.  Apart from the nutritional superiority of 14% fish meal-based...

Seychelles tuna bulletin : fourth quarter 1988
Provedor de dados: 20
Autores: Seychelles Fishing Authority.
The number of purse seiners active in the Western Indian Ocean during the fourth quarter of 1988 increased gradually from 45 in October to 48 in December.  This represents an increase over the same period last year, when 41 vessels were present. There was also a considerable improvement in the performance of the fishing fleet compared to the two previous years.  Catch rates for 1988 were estimated at 29 MT/day compared to 18 MT/day in 1987 and 15 MT/day in 1986.  The proportion of yellow fin in the catch moreover increased from 38% in 1987 to 47% in 1988 with a corresponding decline in the percentage of skipjack, from 61 to 52 percent. The fishing pattern during 1988 however followed an almost similar trend as previous years with yellow fin catch rates...

La fragilité du secteur de la pêche artisanale lui impose un encadrement et un suivi permanents. A cet effet le CNROP dont le rôle est de contribuer à la promotion et au développement d’une flottille artisanale par l’amélioration des techniques de pêche, a organisé une enquête-cadre en 1985 le long du littoral mauritanien. Cette mission, dont le but est de recenser les pêcheurs, le parc existant, les engins de pêche, et autres informations complémentaires relatives aux activités de la pêche artisanale, a été réalisée en deux phases distinctes : - La première phase a été réalisé en juillet (saison chaude et de faible activité) ; - la deuxième phase a été réalisée en décembre (saison froide et d’intense activité). Le choix de ces deux périodes permet...

Provedor de dados: 27
Autores: Huys, R.
A new genus and species of misophrioid copepod is described from an anchihaline lava pool on Lanzarote, Canary Islands. Boxshallia bulbantennulata gen. et spec. nov. lacks any trace of a carapace, possesses a genital double somite, and can be distinguished from other misophrioids by the presence of a bulb-shaped process on the first antennular segment, the loss of the inner coxal spine in leg 1 and the presence of 3 setae on the mandibular basis. The new genus also exhibits many plesiomorphic features such as the 27-segmented antenulla and the biramous leg 5 with a 2-segmented protopod and a well developed intercoxal sclerite in the female. On the basis of urosome segmentation and gonopore location, the holotype of Dimisophria cavernicola Boxshall &amp;...

A female and three males of &lt;i&gt;Procamacolaimus tubifer&lt;/i&gt; Gerlach, 1953 are described and illustrated from Cape Receife Beach, Port Elizabeth. &lt;i&lt;P. africanus&lt;/i&gt; sp.nov. is also described from Cape Receife Beach. It is compared with &lt;i&gt;P. tubifer&lt;/i&gt; which it resembles but from which it can be differentiated by length of the buccal cavity, amphid size and the shape of the spicules. &lt;i&gt;Eontolaimus capensis&lt;/i&gt; gen.nov., sp.nov. is described, also from the same sandy beach. This new genus is related to &lt;i&gt;Deontolaimus papillatus&lt;/i&gt; de Man, 1880 from which it can be distinguished, among other things, by the absence of a tooth-like structure in the buccal cavity and the presence of pre-anal tubuli.

Autores: Bergmans, M.; Janssens, P.P.M.
The influence of the salinity on the performance of the sibling species &lt;i&gt;Tisbe holothuriae&lt;/i&gt; and &lt;i&gt;T. battagliai&lt;/i&gt; in pure and mixed cultures was studied, using laboratory stocks adapted to 32 pro mille for over 175 generations. Cohort studies show that &lt;i&gt;T. holothuriae&lt;/i&gt; has higher growth rates (R&lt;sub&gt;0&lt;/sub&gt; and r) at 32 pro mille, &lt;i&gt;T. battagliai&lt;/i&gt; at 20 pro mille. The latter's life cycle is much less affected by the difference in salinity. 'De Wit' replacement series were used to study competitive interactions. Without water renewal, &lt;i&gt;T. holothuriae&lt;/i&gt; eliminates its sibling species in less than 2 generations, apparently through chemical interference. With water...

Gelyelloida, a new order of stygobiont copepods from European karstic systems
Provedor de dados: 27
Autores: Huys, R.
A new order, Gelyelloida, is proposed for Gelyella Rouch &amp; Lescher-Moutoué,1977(ex Harpacticoida), an enigmatic genus of freshwater-inhabiting copepod from European karstic systems. The new order is characterized by a unique combination of generalised gnathostomous mouth parts and unusual derived features, some of them suggesting a possible neotenic origin for the order. It is suggested that gelyellids have had a long evolutionary history and separated as an early offshoot of the main cyclopoid lineage.

The implications of heterozygosity in the scallop &lt;i&gt;Placopecten magellanicus&lt;/i&gt; (Gmelin)
Provedor de dados: 27
Autores: Volckaert, F.A.M.J.
In many instances, variation in phenotypic traits has been correlated with electrophoretic heterozygosity of plants, vertebrates and invertebrates. Enhanced growth of selected heterozygous molluscs has been attributed to lower energetic requirements for basal metabolism. I investigated the correlation between single- and multiple-locus heterozygosity and phenotype of the juvenile scallop &lt;i&gt;Placopecten magellanicus&lt;/i&gt; (Gmelin). Two questions were being asked: do heterozygous scallops grow faster and which metabolic processes are affected by the degree of heterozygosity? No significant correlation was observed between genotype (scored at 6 polymorphic loci) and growth in six different samples of juvenile scallops, all belonging to the same time...

Heavy metal contamination in sediments from the Belgian coast and Scheldt estuary

Autores: Araújo, M.F.D.; Bernard, P.C.; Van Grieken, R.E.
Sixty-two samples of total sediments and the separated clay/silt fractions were analysed by the energy-dispersive X-ray fluorescence spectrometry to evaluate the pollution level and the trends in samples collected along the Belgian coast over a period of 6 yr and at four stations located in the Scheldt estuary where two of these were sampled periodically for 4 yr. Three correction methods for grain size effects were applied, either to the bulk sediment samples or to the clay/silt size fractions, and the results were compared. Local variations on the concentrations in some of the elements determined were used to establish whether they result from an anthropogenic or natural origin. The level of pollution was assessed as a function of the location, sampling...

Autores: Martens, P.M.; Schockaert, E.R.
From a comparative study of the ultrastructure of the hard parts in the copulatory organ of the Proseriata, E. Martens (1984) concluded for the monocelidid genera she studied that in all except the genus &lt;i&gt;Archimonocelis&lt;/i&gt;, the spines and styles are basal lamina differentiations: the autapomorphy for the monophylum Monocelididae.&lt;i&gt;Archimonocelis&lt;/i&gt; has intracellular hard parts as in all other Proseriata, clearly the plesiomorphic condition. At the same time it was also found from a karyological viewpoint that there are arguments that &lt;i&gt;Archimonocelis&lt;/i&gt; does not belong to the Monocelididae at all.

Provedor de dados: 27
Autores: De Vocht, A.J.-P.; Schockaert, E.R.
Ultrastructural data on the proboscis epithelia of Eukalyptorhynchia have been given by Rieger and Sterrer (1975) for Bertiliellidae, by Doe (1976) for Gnathorhynchidae, by Reuter (1975) and Schockaert and Bedini (1977) for Polycystididae. Only the latter authors dealt with the overall organization of the epithelia in the proboscis, and this for &lt;i&gt;Polycystis naegelii&lt;/i&gt;. The anatomy of the proboscis is indeed an important element in the taxonomy of the Eukalyptorhynchia. It is to be expected that the ultrastructure will provide further clues to indicate phylogenetic relationships between the major taxa in Eukalyptorhynchia when more data become available. In view of further comparative studies on the ultrastructure of the proboscis of...

Provedor de dados: 27
Autores: Huys, R.
The cylindropsyllid type genus Cylindropsyllus Brady, 1880 is revised and a new species C. kunzi sp.n. from the North Sea is added. Of the other species a detailed redescription and figures are given, distribution records are compiled and some phylogenetic data are presented. It is suggested that Cylindropsyllus and the monotypic Cylinula Coull, 1971 are sister groups, the latter being the apomorphous lineage because of the unisegmented mandibular palp and the prehensile endopodite P1. Cylindropsyllus sp. Monard, 1935 cannot be assigned to any known species. An amended diagnosis of the genus Cylindropsyllus and a comparison with Cylinula are presented.

Autores: Herman, P.M.J.; Vranken, G.
An energy budget was constructed for the marine nematode &lt;i&gt;Monhystera disjuncta&lt;/i&gt;. Respiration was measured with a modified Cartesian diver technique, in which the nematodes were kept in agar inside the diver 'head'. The relationship between respiration and body weight was: R=1.53 W&lt;sup&gt;0.75&lt;/sup&gt;. Body growth was exponential during the juvenile phase, with a growth rate equal to 0.61 d&lt;sup&gt;-1&lt;/sup&gt;. After maturation the growth rate fell to 0,17 d&lt;sup&gt;-1&lt;/sup&gt;. Food uptake was measured in experiments with radiolabeled bacteria. In one series of experiments the accumulation of radiolabel in the nematodes was followed. In a second series the decrease in labeling was followed when pre-labeled nematodes fed on...

&lt;i&gt;Artemia&lt;/i&gt; cysts collected from inoculation experiments in Cam Ranh salterns are evaluated for their potential use in aquaculture. Cyst biometrics, hatching quality, naupliar fatty acid profile and naupliar growth were measured and compared to reference &lt;i&gt;Artemia&lt;/i&gt; strains. Cyst characteristics reveal that the parthenogenetic strain (PR China) used in inoculations, was eliminated from the environment and that the remaining brine shrimp are likely to be composed of Macau and Great Salt Lake &lt;i&gt;Artemia&lt;/i&gt; strains, and of their cross-breds. Differences in cyst diapause deactivation characteristics between Macau and Great Salt Lake &lt;i&gt;Artemia&lt;/i&gt; may have resulted in the disappearance of Macau...

Horizontal distribution of the Plathelminthes in a sandy beach of the Belgian coast
Provedor de dados: 27
Autores: Jouk, P.E.H.; Martens, P.M.; Schockaert, E.R.
Studies of the horizontal distribution of the Plathelminthes in sandy beaches have up to now mainly been carried out on the German island of Sylt where the beaches consist of a steep "Prallhang" and a flat wadden area. Beaches of the Belgian coast are very flat, only gently sloping and with a different sediment compared to the Sylt beaches. This study reports on the distribution of the turbellarians in such a flat beach; the discussion is mainly focussed on the comparison with the results of the German investigators.

On the generic boundaries within the marine interstitial Latiremidae (Copepoda: Harpacticoida)
Provedor de dados: 27
Autores: Huys, R.; Kunz, H.
Character analysis of the various species of the marine interstitial family Latiremidae revealed that they should be placed in at least three genera instead of the single genus Delamarella Chappuis. The original type genus Latiremus Bozic is reinstated and comprises L. eximius only. The mediterranean genus Delamarella includes D. arenicola, D. karamani and D. galateae; the latter two probably constitute a separate taxon. D. phyllosetosa is removed from the genus Delamarella and is considered the type species of a new genus Arbutifera. The significance of characters such as the incorporation of the first pedigerous somite, the fusion of the genital somites and the antennal segmentation is stressed. Two main evolutionary lineages are recognized within the...

Sexual dimorphism in Aegisthid cephalosomic appendages (Copepoda, Harpacticoida): a reappraisal
Provedor de dados: 27
Autores: Huys, R.
The cephalosomic appendages, including the rostrum, are redescribed in the bathypelagic harpacticoid Aegisthus mucronatus Giesbrecht, 1891 (Aegisthidae). Profound sexual dimorphism was found in all cephalosomic appendages. For the first time reference is made to the presence of a mandible in the male and figures are given for the male maxillula. Distinct sexual differences are also observed in the structure of the labrum and the labium. The structure and ornamentation of the male antennula clearly shows that the Aegisthidae belong to the monophyletic group Cervinioidea, including also the Rotundiclipeidae and Cerviniidae. Brief comments are made on the nature of the first pedigerous somite, the structure of the anal somite and of the caudal rami. The...

Studies of the life-history and energetics of marine and brackish-water nematodes: 1. Demography of &lt;i&gt;Monhystera disjuncta&lt;/i&gt; at different temperature and feeding conditions
Provedor de dados: 27
Autores: Vranken, G.; Herman, P.M.J.; Heip, C.H.R.
Aspects of the demography of &lt;i&gt;Monhystera disjuncta&lt;/i&gt; were investigated at different feeding conditions (monoxenic cultures with different bacterial strains, and different densities in the feeding suspension with one strain). Embryonic development time, minimum generation time, egg deposition rate and adult longevity depend on temperature, quality and quantity of food offered. Body mass at maturity is an allometric function of food density. It is shown that a previously inferred selectivity in food uptake is an artifact of culture conditions. pH buffering and addition of sterols permit culture of the species on a wide variety of bacterial strains. &lt;i&gt;M. disjuncta&lt;/i&gt; is less well adapted to take advantage of high food density...

Stygofauna of the Canary Islands: 10. Rotundiclipeidae Fam. Nov. (Copepoda, Harpacticoida) from an anchihaline cave on Tenerife, Canary Islands
Provedor de dados: 27
Autores: Huys, R.
A new family Rotundiclipeidae is proposed for an anchihaline cave-dwelling harpacticoid Rotundiclipeus canaricnsis gen. nov:, sp. nov. from Tenerife, Canary Islands. It is suggested that the family should be placed in the Cervinioidea grouping also the chiefly deep-sea Cerviniidae and the mesopelagic Aegisthidae. Because of numerous unique and unusual derived traits, the smallsized Rotundiclipeidae are regarded as the advanced sistergroup of the Cerviniidae-Aegisthidae complex whilst the Cerviniidae are standing closest to the cervinioid ancestor. In the context of Stock's (1986) conclusion it is postulated that both the cave-dwelling Rotundiclipeidae and the deep-sea Cerviniidae are originated from a common shallow water ancestor.

Autores: Huys, R.
&lt;i&gt;Caligopsyllus primus&lt;/i&gt; Kunz, 1975, reported from tidal pools near East London (South Africa), is redescribed and figured on the basis of type material. An amended diagnosis of the genus &lt;i&gt;Caligopsyllus&lt;/i&gt; Kunz, 1975 is presented. Cladistic analysis falsified the hypothesis of a close relationship between &lt;i&gt;Caligopsyllus&lt;/i&gt; and &lt;i&gt;Kliopsyllus&lt;/i&gt; Kunz, 1962, favouring instead a link with &lt;i&gt;Apodopsyllus&lt;/i&gt; Kunz, 1962. The morphological modifications are discussed within the context of a possible ecto-associated life-style. Finally, a standard format of abbreviations and terminology is proposed for the paramesochrid caudal ramus.

Hazard prediction and relevance of laboratory-scale studies
Provedor de dados: 27
Autores: Persoone, G.
Predictive hazard assessment of chemicals, pure, in mixtures, or as wastes, is based on the comparison of exposure to effect concentrations. Experimental determination of no-effect levels can be carried out at various levels of biological organisation: within the organism (suborganismal), on individual species (organismal), or with biological communities (supraorganismal). The difficulty of predictive effect analysis consists of relating endpoints determined at various levels of biological organisation to the impact on structure and/or function impairment of natural ecosystems. Examples are given of effect-extrapolations which have been validated at different levels, and which carry promising predictive values.

A test guideline has been established for determining the potential of a chemical to taint seafood. This guideline, based on the exposure of fish and the evaluation of the imparted taint by a triangular test, has been evaluated in a small ring test in which five laboratories tested four chemicals with three fish species. The guideline also contains a procedure for estimating the loss of taint from the test species during a depuration phase in clean water. None of the following factors appeared to have a large or systematic effect on the evaluation of the potential to cause taint: the performing laboratory; type of water used (sea- or freshwater); fish species; evaluation by flavour or by odour; method of preparation and presentation of samples for sensory...

OPTIMAL USE OF QUALITATIVE MODELS: AN APPLICATION TO COUNTRY GRAIN ELEVATOR BANKRUPTCIES
Provedor de dados: 31
Autores: Kaylen,   Michael S.; Devino,   Gary T.; Procter,   Michael H.
Qualitative models can be used for decision making under uncertainty. This provides a useful framework for evaluating the models. If the costs for every action/state of nature combination are known, decisions made using a well-calibrated model would result in actual costs being close to expected costs. In addition, the actual cost can be compared to the cost of perfect foresight actions, giving a bound on the value of a better model. Application of these procedures is made using a logit model developed to predict Missouri country grain elevator bankruptcy.

LOSSES IN THE LOGISTICAL SYSTEM: THE CASE OF PERISHABLES
Provedor de dados: 31
Autores: Beilock,   Richard P.
The potential for losses in the logistical system is particularly great for perishables, as they are sensitive to time, climatic conditions, and handling. However, the literature is virtually silent regarding the extent and causes of such losses. This paper reports the results of a study of freight claims for produce and ornamentals. The results indicate that losses are of a magnitude that should merit the attention of shippers, carriers, and receivers. Various loss reducing measures are suggested.

ESTIMATED HEDGING RISK WITH CASH SETTLEMENT FEEDER CATTLE FUTURES
Provedor de dados: 31
Autores: Elam,   Emmett W.
Beginning with the September 1986 contract, feeder cattle futures have been settled based on cash settlement rather than physical delivery. The effect that cash settlement will have on hedging risk for feeder cattle was estimated using Arkansas prices for 1977-86, but the results should be representative of other markets. For 600-700 pound steers and heifers, hedging risk is estimated to be lower for hedges placed in the new cash settlement contract. For steers and heifers weighing less than 600 pounds, hedging risk is estimated to be lower for the cash settlement contract for fall hedges, whereas hedging risk is estimated to increase for spring hedges.

GROUNDWATER PROTECTION POLICY AND AGRICULTURAL PRODUCTION: A RECURSIVE STOCHASTIC ANALYSIS
Provedor de dados: 31
Autores: Baker,   Brian P.
Contamination of groundwater by agricultural practices presents a dilemma between protecting a vital resource and maintaining a valuable part of the economy.  Policies to balance these objectives are presented.  In addition to an historical baseline, policies that ban certain pesticides, taxes and subsidies, and control cultural practices are also considered.  A model is developed to reflect the current state of agriculture in Eastern Suffolk County.  This model consists of a recursive programming component, which has input for it generated by a stochastic model of Colorado potato beetle pest dynamics and management strategies to control those pests.  While income is reduced by banning pesticides, the reduction is small when compared with the improvement...

A POSITIVE ROLE FOR GRADUATE AGRIBUSINESS PROGRAMS IN AGRICULTURAL ECONOMICS
Provedor de dados: 31
Autores: Robbins,   Lynn W.
Agribusiness graduate students should do problem-solving and take business courses to understand the environment in which they will practice their theory.  The longer we wait to teach them application, the greater are the chances of losing our critical mass in terms of relevancy and political support.  We can, and should, cultivate a broader range of agribusiness problems and clientele groups.  We can effect change immediately by doing more agribusiness research.  We can assure our long-run existence through a stronger political support base by educating our graduate students in the ways of firm-level agribusiness application.

Interstate Trade in Market Milk
Provedor de dados: 31
Autores: Small,   Annette M.
Interstate trade has been a feature of the policy debate for several agricultural products in Australia, including wheat, eggs and dairy products. Interstate trade in market milk has been an on-going policy issue since the early 1970s, but has largely been prevented by informal agreements and threats of retaliation. Formal arrangements preventing free interstate trade are unlawful, being contrary to Section 92 of the Australian Constitution. Due to recent changes in the marketing arrangements for manufacturing milk, interstate trade in market milk now has the potential to rapidly deregulate the whole Australian dairy industry, with the consequent problems of resource dislocation and adjustment The potential impacts of interstate trade in market milk are...

THE WAEA AS HEIR-APPARENT OF A REGIONAL MANDATE
Provedor de dados: 31
Autores: Gessaman,   Paul H.
Sixty years ago agricultural economists established a regional professional organization now called the WAEA.  As it evolved, interest-based member constituencies emerged.  Perspective for discussion of WAEA actions, activities, and roles as the heir-apparent professional organization for western region agricultural economists is provided through identification of conditions and problems endemic to the region, and commentary on the decline of alternative regional differences.

AN ECONOMIC ANALYSIS OF CONTRACTING ARRANGEMENTS USED BY THE MINNESOTA TURKEY INDUSTRY
Provedor de dados: 31
Autores: Dornbush,   Calvin W.; Boehlje,   Michael.
The objective of this report is to summarize knowledge about contracts used in the turkey industry which may be helpful in initiating contracts in other agricultural enterprises.  Characteristics common to all Minnesota contracts are described.  Contracts are divided into three main categories and similarities of contracts within those categories are described.  Budgets developed at the University of Minnesota were used to calculate the return to labor and management (RLM) for each type of contract.  Feed costs were set at six levels to show how risk and return are shared as feed costs change.  Historic wholesale prices were used to establish a probability distribution for effective prices paid to growers.  The Agricultural Risk Management Simulator (ARMS)...

Dynamic oligopoly: estimation and tests of market structure
Provedor de dados: 31
Autores: Karp,   Larry S.; Perloff,   Jeffrey M.
A linear-quadratic dynamic oligopoly model is developed and applied to the world coffee export market. The model nests various market structures using either open-loop or feedback strategies. The theoretical properties of this model are described. For given observed behavior, the assumption of feedback strategies implies a less competitive market structure than open-loop strategies.

THE DEMAND FOR BEEF PRODUCTS:  CROSS-SECTION ESTIMATION OF DEMOGRAPHIC AND ECONOMIC EFFECTS
Provedor de dados: 31
Autores: Heien,   Dale; Pompelli,   Greg.
This paper presents estimates of the economic and demographic effects on the demand for steak, roast, and ground beef. Using an almost ideal demand system, the results indicate that demand is inelastic for steak and ground beef, elastic for roast, cross-price effects are significant, and all goods are Hicks-Allen substitutes. The impact of certain demographic effects, such as household size, region, tenancy, and ethnic origin, was generally quite significant. Other demographic variables, such as employment status, shopper, and occupation, were generally not significant.

ECONOMIC ASPECTS OF SOYBEAN PRODUCTION AND MARKETING IN INDONESIA
Provedor de dados: 31
Autores: Pakasi,   Piet Petrus.
Indonesia is a great archipelago, consisting of five main islands and about 13,000 smaller ones.  Topographical features and soil types can be classified into three major groupings:  1) mountainous land area, 2) level or undulating to hilly land, and 3) low swampy lands.   Indonesia is the fifth most populous country in the world after China, India, Russia, and the United States of America.  It is predominantly a rural society, as well as an agricultural country.  Agricultural policy has emphasized intensification, extensification, diversification and rehabilitation.  This policy has been supported by the development of better irrigation schemes, improved on-farm water management, implementation of special intensification packages and increased labor...

An Open Economy Model of Political Influence and Competition Among Rent Seeking Groups
Provedor de dados: 31
Autores: Roe,   Terry L.; Yeldan,   A. Erinc.
The paper develops a formal model of government's economic decisions as influenced by private agents within the context of neoclassical political economy. The government is assumed to form preferences over interest groups in the economy; in turn these preferences are influenced by the rent seeking behavior of these groups. An open, two-household, two-sector general equilibrium model is constructed to depict an environment in which preference-maximizing (rational) individuals allocate otherwise productive labor to directly unproductive rent seeking activities in order to exert political pressure on the government's choice of policy instruments. With the aid of five comparative-static experiments, the game-theoretic component and the second-best nature of...

UTILITY-EFFICIENT PROGRAMMING FOR WHOLE-FARM PLANNING
Provedor de dados: 31
Autores: Hardaker,   J. Brian; Patten,   Louise H.; Pannell,   David J.
A programming technique, utility-efficient programming, is developed for farm planning under risk. The objective function is the parametric sum of two parts of the utility function in which the degree of risk aversion varies systematically with the parameter. This technique has several advantages over those previously available: a number of types of utility functions are applicable including ones exhibiting decreasing risk aversion; the degree of risk aversion can be limited to a plausible range; the form of the distribution for activity net revenues is flexible; and the technique can be used with available algorithms. The method is illustrated using a parametric linear programming algorithm.

Weed Management: A Review of Applied Economics Research in Australia
Provedor de dados: 31
Autores: Pannell,   David J.
Australian research into the economics of privately and publicly funded weed control is reviewed. Of the published studies that consider farm-level problems, most have been simplistic. Complexities which affect a farmer's optimal control strategies for crop and pasture weeds are outlined. The determination of herbicide rates on an economic basis is proposed as an area for further work. The traditional economic threshold concept is not suitable for this purpose. Studies of the economics of public weed control programs are slightly more common than farm-level studies in the literature, although work on public weed problems has focussed on just a few weed species. Future directions for weed economics research are suggested.

Autores: Mucavele,   Firmino Gabriel.
Agriculture surveys and literature establish that sorghum was of the most important food crops in Mozambique.  A large number of farmers have been shifting production gradually from sorghum to maize production despite its susceptibility to drought.  The general objective of this study is to identify the factors responsible for decline of sorghum production in Mozambique.  Comparative analysis between sorghum and maize are done.  Enterprise budgets and break even analysis for both sorghum and maize are presented and discussed.  Supply functions for sorghum and maize from 1950 to 1985 are estimated.  It is concluded that the major factors responsible for sorghum production decline are the lack of security in the country side, drought during the last ten...

A METHOD FOR EVALUATING SUPPLY RESPONSE TO PRICE UNDERWRITING
Provedor de dados: 31
Autores: Fraser,   Rob W.
In this paper a method for evaluating the supply response of individual producers to a price underwriting scheme is presented. The method includes precise formulae to take account of the impact of price underwriting on the producer's uncertain conditions. The Australian Wheat Board's guaranteed minimum price scheme is taken as a specific example of price underwriting in practice. Results show the scheme to lead to only relatively small supply responses. The impact on producer behaviour of an increase in price uncertainty in the presence of an underwriting scheme is also demonstrated in the paper.

In recent years, plant breeders' rights (PBR) has become a controversial subj ect worldwide. This paper reports the results of a survey of the seed distribution industries in the nine member countries of the International Union for the Protection of New Varieties of Plants (UPOV) as well as the seed trade in the United States (U.S . ) and Canada. The general consensus of the UPOV members was that PBR had resulted in increased private investment in plant breeding and that there had been a shift toward more basic research in the public sector. The findings in the U.S. were similar except that there the changes were perceived to be more crop specific with less funding available for public sector research. In Canada, the major concern centered around the...

The Importance of Agriculture: what hope for agriculture, and what needs doing?
Provedor de dados: 31
Autores: Lloyd,   Alan G.
In recent years both incomes and morale have slumped in Australian agriculture. This has happened before, and today's pessimism is just as excessive as previously. There are exaggerated fears that agriculture has no future. Equally, there are some exaggerated hopes, as to the extent to which we can rapidly and effectively restructure the economy away from agriculture, and restructure agriculture away from the "broadacre industries". The key words, with regard to the latter objective, are value added, high-tech (sunrise) and infant industries, and better marketing.  By contrast, the conclusion suggested in this paper is that traditional broadacre agriculture will remain, for decades, vitally important in reducing the balance of payments deficit which is our...

INVOLVEMENT OF AGRICULTURAL ECONOMICS IN GRADUATE AGRIBUSINESS PROGRAMS:  AN UNCOMFORTABLE LINKAGE
Provedor de dados: 31
Autores: Biere,   Arlo W.
Departments of agricultural economics face a changing environment.  Some argue for the adoption of the Master of Agribusiness degree.  I argue that agribusiness in not well differentiated from agricultural economics and that the forte of agricultural economics departments is teaching applied economics, not teaching management.  Furthermore, in today's dynamic, open economy, a good understanding of economics is more valuable than ever before.  Rather than leave our area of strength, we should look to improve our current degree programs given today's business needs.

THE DEMAND AND SUPPLY OF U.S. AGRICULTURAL EXPORTS: THE CASE OF WHEAT, CORN, AND SOYBEANS
Provedor de dados: 31
Autores: Haniotis,   Tassos; Baffes,   John; Ames,   Glenn C.W.
The demand for and supply of U.S. wheat, corn, and soybean exports is specified in a dynamic framework.  Obtained results indicate differences in the export behavior of each product.  U.S. corn exports are elastic, while U.S. soybean exports exhibit an inelastic response.  For wheat, the derived elasticity of export demand had a positive sign.  Hypothesis testing validated the dynamic structure of the estimated models in all markets.  Stability properties were confirmed in export markets of corn and soybeans, but results were inconclusive for the wheat market.  Adjustment coefficients indicate that exports and export prices do no adjust immediately to their equilibrium levels.  Multiplier impacts indicate a stable path of convergence for all markets, with...

Public or Private Monopoly?
Provedor de dados: 31
Autores: Quiggin,   John C.
Almost all aspects of the current policy debate over grain handling, transport and marketing turn on the problem of monopoly. The essential problem is that, in the presence of extensive scale economies, the perfectly competitive market of the textbooks cannot be sustained. Policy makers are left with three broad alternatives, each of which seems more notable for its disadvantages than its advantages. The basic choices are public monopoly, regulation and unregulated private monopoly.

COMMODITY BONDS:  A POTENTIAL RISK MANAGEMENT INSTRUMENT FOR CAPITAL CONSTRAINED COMMODITY PRODUCERS
Provedor de dados: 31
Autores: Ball,   Richard J.
The commodity-linked bond offers a potential means for producers of primary goods both to raise capital and to hedge against output price risk.  Commodity bonds are distinguished from conventional bonds in that their return structure is denominated in quantities of the underlying commodity.  Optimal levels of bond issues and commodity production are derived, first for producers whose only source of capital is the revenue raised by issuing bonds, and then for producers who can raise capital either by issuing bonds or by borrowing commercially.  The models used are extensions of the standard models of futures market hedging.  Relatively less risk averse producers are found to be unwilling to pay the premium for transferring the risk implicit in bond sales,...

Autores: Shumway,   C. Richard; Jegasothy,   Kandiah; Alexander,   William P.
Technical change and the extent to which commodity supplies and input demands are interrelated in Sri Lankan peasant agriculture are explored in this paper. Using a multiple-product dual model, a seemingly unrelated system of product supply and input demand equations is estimated for four crops and four variable inputs. Restrictions based on competitive behaviour and a twice continuously-differentiable production function are maintained in the non-linear least squares estimation. A number of important interrelationships in individual product supplies and input demands are identified, further documenting the need to account for intercommodity production relationships in econometric and simulation studies and in policy formulation. Non-joint production and...

COTTON EXPORTS: ANALYSIS OF THE RELATIONSHIPS BETWEEN SALES AND SHIPMENTS
Provedor de dados: 31
Autores: Ayuk,   Elias T.; Ruppel,   Fred J.
Relationships between cotton export sales and export shipments are examined, and a quarter-specific lag structure is estimated. Two econometric systems are estimated, one employing export shipments and the other using export sales. Results indicate that sales are more sensitive to changes in economic variables than shipments and that stocks net of outstanding export sales are more responsive to price and interest rate changes than gross stocks. Sales and shipments are different variables and cannot substitute for one another in econometric modelling. Use of export sales data should be considered in estimation of export demand and stock demand parameters.

Feeder cattle prices are determined by the interaction of many factors.  This study uses 1986 and 1987 Kansas feeder cattle auction data to investigate the impact of a wide variety of physical characteristics, many of which have not been used in previous studies on feeder cattle prices.  Unlike previous studies, this analysis explicitly incorporates changes in feeder cattle market fundamentals during the data collection period and also allows price differentials to vary by sex and weight.  Weight, weight-squared, lot size, lot size-squared, health, muscling, frame size, condition, fill, breed, presence of horns, and time of sale are significant factors affecting feeder cattle prices on any given day.  Several physical traits also exhibit different seasonal...

The Share Market Crash and Australian Agriculture
Provedor de dados: 31
Autores: Freebairn,   John W.
The 20 to 45 per cent fall in indexes of share market prices in mid-October 1987 was a worldwide phenomenon. It represented a sharp reversal to a five-year period of sustained increases in stock prices. It is important to assess the implications of the crash for Australian agriculture in the context of the world scene, because of the worldwide stock market crash, because of the interdependence of world financial markets and because of Australian agriculture's dependence on world markets for 60 per cent of its sales. This note looks at the likely implications of the stock market crash on Australian agriculture in terms of direct effects on land prices; direct effects on world economic activity; effects of lower economic activity on commodity markets; and...

TAX REFORM AND BEEF COW REPLACEMENT STRATEGY
Provedor de dados: 31
Autores: Innes,   Robert; Carman,   Hoy F.
This paper models optimal beef cow replacement strategy in a stochastic environment under U.S. income tax rules effective before and after the Tax Reform Act of 1986. Under each tax regime, the producer's buy versus raise decision and optimal culling age choice are analyzed. Per-cow profit levels are also calculated. Results of the numerical analysis indicate that tax law changes, particularly the loss of the capital gains exclusion and restrictions on preproduction expensing, will have significant effects on both optimal decisions and profitability of beef cow operations. When provisions of the Tax Reform Act of 1986 are fully effective in 1988, the optimum age for culling beef cow will increase, as will the after-tax costs of beef cow operations.

Bilateral Harmonization of EC and U.S. Agricultural Policies
Provedor de dados: 31
Autores: Mahe,   Louis Adrien Pascal; Tavera,   Christophe.
Agricultural policies in both Europe and the United States provide commodities with an excessively high and distorted pattern of support. The economic interdependencies of the policies give rise to adverse fiscal and economic costs, which are viewed as disharmonies in the existing policy measures both within and between the two regions. Unilateral and simultaneous EC and U.S. policy changes are simulated with an international trade model. They are carried in three steps: (1) grains and feeds, (2) beef and dairy, and (3) sugar. Both cross effects and own effects are examined on typical policy targets. Results suggest that while world prices are sometimes drastically altered, the magnitude of cross effects is small and sometimes ambiguous compared to own...

Evaluation of Restructuring Alternatives for the Banks for Cooperatives
Provedor de dados: 31
Autores: Hopkin,   John A.; Sporleder,   Thomas L.; Padberg,   Daniel I.; Knutson,   Ronald D.
The farm financial crisis, combined with deregulation of the U.S. banking system, has created a new environment within which the Farm Credit System competes. Despite their unique business clientele, the Banks for Cooperatives (BCs) have been adversely affected by this changed environment. In 1987, the BCs requested an economic analysis of possible consolidation alternatives, with emphasis on the economies of size they might achieve. Summary results of that analysis are presented here. A 47 basis point reduction in interest rates charged borrowers was estimated to result from a total consolidation of the BCs.

Optimal Equity Recovery for a Cooperative Financial Institution
Provedor de dados: 31
Autores: Tauer,   Loren W.; Weersink,   Alfons.
A model is developed that shows the usefulness of dynamic optimization in deriving optimal equity recovery strategies for a cooperative lending institution. The objective is to minimize the cost of a member borrowing over time. An interest rate surcharge, above the cost of funds and operating cost, is the control variable to be determined. The financial position of the cooperative is described by equity and loan volume, which are the state variables. Applications show how the surcharge, loans, and equity change over time as model parameters are changed.

THE AGRICULTURAL RISK MANAGEMENT SIMULATOR MICROCOMPUTER PROGRAM
Provedor de dados: 31
Autores: King,   Robert P.; Black,   J. Roy; Benson,   Fred J.; Pavkov,   Patti A.
The Agricultural Risk Management Simulator (ARMS) is a microcomputer program designed to help users evaluate strategies for managing yield and price risk in crop farming operations.  Risk management strategies are defined by choices regarding crop mix, the purchase of multiple peril crop insurance, and the use of forward contracting.  Probabilistic budgeting is used to determine the net cash flow probability distribution for each strategy considered.  Flexibility with regard to both sources of probabilistic information and the form of yield and price probability distributions is a noteworthy feature of the program.

WHEAT ACREAGE SUPPLY RESPONSE IN THE UNITED STATES
Provedor de dados: 31
Autores: Burt,   Oscar R.; Worthington,   Virginia E.
The dynamic structure of wheat acreage supply response is considerably more complex than previous studies have recognized.  The distributed lag response is saw-toothed in its pattern, which is believed to eminate from the influence of summer fallow in crop rotations in the Great Plains.  The acreage response elasticity estimate for the Great Plains at mean price was 1.3, and for the aggregate U.S. it was 1.5.  For the Unites States, the proportion of long-run response experienced over the first five years from an increment to price was .24, .44, .70, .95, and. 99.

NEGATIVE MILK SUPPLY RESPONSE UNDER CONSTRAINED PROFIT MAXIMIZING BEHAVIOR
Provedor de dados: 31
Autores: Tauer,   Loren W.; Kaiser,   Harry M.
A conceptual model is formulated that shows that a downward sloping supply function may exist for a profit maximizing firm facing a cash-flow constraint.  The necessary requirement is that at least one factor must be a non-cash input.  The model is tested using analysis of variance on two groups of producers from farm record data, one group facing a binding budget constraint the other group not.  The results indicate that farms facing a cash flow constraint increase output more than farms not restricted by a cash flow constraint in response to a price decrease.

This paper outlines the major trends experienced by Spain's dairy sector in recent decades. It offers tentative explanations of the factors accounting for these observed trends. Implications for the nation's dairy farm sector from entry into the EEC are examined. The paper concludes with some considerations on the possibilities to carry out the necessary technical and structural reforms needed to achieve a viable dairy sector before full application of the mechanisms for the Community's dairy policy takes place.

MALLEE WHEAT FARMERS' DEMAND FOR CROP AND RAINFALL INSURANCE
Provedor de dados: 31
Autores: Patrlck,   George F.
Producers' demand for a crop insurance program with indemnities based on their actual yields and a rainfall insurance program with indemnities based on area rainfall is analysed. Actuarial costs of these hypothetical programs are estimated. Tobit procedures are used to analyse factors influencing the amount which farmers would be willing to pay for the alternative insurance programs. Factors related to the absolute size of risk and capacity to bear risk, as well as personal characteristics and risk attitudes of producers, have effects on the demand for insurance as hypothesised. Problems of adverse selection are associated with the area yield-based program, while both crop and rainfall insurance programs may involve some moral hazard. Producer...

The Determinants of Rice Variety Choice in Indonesia
Provedor de dados: 31
Autores: Pitt,   Mark M.; Sumodiningrat,   Gunawan.
This paper investigates the determinants of rice seed variety choice in Indonesia with respect to a meta-profit function. Varietal choice is modeled as depending on the profitability of high yielding varieties of seed relative to traditional varieties of seed, the schooling of cultivators and factors associated with yield uncertainty and risk aversion. Careful attention is paid to the stochastic structure of the estimated simultaneous equations switching regimes model. The maximum likehood method applied to Indonesian farm-level data is complicated by endogenous regressors and heteroskedastic errors. Adoption of high yielding varieties was found to be positively associated with its relative profitability, the likelihood of flooding, quality of irrigation...

Market Effects of In-Kind Subsidies
Provedor de dados: 31
Autores: Houck,   James P.
In-kind price subsidies are a new and important feature of U.S. agricultural policy. Yet the market effects of such subsidies have not been widely discussed in the professional literature even through they differ importantly from similar cash subsidies. This paper examines in-kind subsidies with simple, static demand and supply functions. In-kind price subsidies push down prices to favored buyers and increase total sales relative to no subsidy or to an equivalent cash subsidy. Inventory holdings by the subsidizing authority are diminished. However, the effects of an in-kind subsidy upon prices received by sellers and commercial sales volume (net of stock disposals) are problematic, depending upon the price elasticity of demand in the subsidized market. If...

Dynamic dumping
Provedor de dados: 31
Autores: Berck,   Peter; Perloff,   Jeffrey M.
A low-cost foreign firm lowers its initially high price–dumping if necessary– until it drives the higher cost domestic firms out of business, whereupon it raises its price. At no time, however, does the foreign firm predate (price below its marginal cost). Tariffs, quotas, and other policies that mandate a minimum number of domestic firms do not qualitatively change the price path (high price, low price, and limit price). The optimal tariff in this dynamic analysis is lower than the optimal tariff in a static analysis (to allow consumers to take advantage of the low-price period).

GARCH TIME-SERIES MODELS:  AN APPLICATION TO RETAIL LIVESTOCK PRICES
Provedor de dados: 31
Autores: Aradhyula,   Satheesh V.; Holt,   Matthew T.
This article applies recent developments in time-series modeling to analyze the retail prices of beef, pork, and chicken. Specifically, generalized autoregressive conditional heteroscedasticity (GARCH) models were fitted to these data to determine if, unlike more traditional time-series models, the conditional variances of the underlying stochastic processes are nonconstant. The estimation results indicate that the constant conditional variances assumption can be rejected. Furthermore, ex post forecast intervals generated from the GARCH processes indicate that the forecasting accuracy of the estimated models has varied widely over time with substantial volatility occurring during the 1970s and early 1980s.

This study illustrates the differences in empirical results due to data measurements and estimating procedures when applying the single index market model in agriculture.  Gross and net return betas along with systematic and unsystematic risk proportions are estimated and found to be different.  The stochastic coefficients model is used to show the difference in beta-risk estimates compared with the traditional fixed coefficients OLS procedure.  A third estimating technique, weighted least squares/Prais Winsten method, is also proposed.

A THEORETICAL DISCUSSION OF THE ECONOMIC EFFECTS OF BUFFER STOCKS AND BUFFER FUNDS
Provedor de dados: 31
Autores: Simmons,   Phil.
It has been established that the absence of risk markets justifies market intervention in principle. The form of intervention that has been discussed most widely in the literature is the buffer stock. This paper points out that other forms of intervention, specifically buffer funds, are likely to perform better. The analysis shows that buffer funds are likely to outperform buffer stocks because they address market failure more directly. A sub-theme developed in this paper is that since buffer funds are enforced saving, it follows that policies that address capital market failure are likely to dominate buffer funds and buffer stocks in welfare terms.

THE PROBABILITY DISTRIBUTION OF THE AVERAGE MARGINAL PRODUCTS OF COBB-DOUGLAS FACTORS WITH APPLICATIONS
Provedor de dados: 31
Autores: Alaouze,   Chris M.
The comparative productivity of inputs is often the focus of applied studies of production. For example, one might wish to compare the marginal product of water in irrigation districts to provide guidelines for capital investment in new water projects or to assist in water allocation decisions.  The purpose of this note is to illustrate a straightforward econometric method for making such comparisons. It is assumed that panel data are available for T periods on N cross-sectional units and that output is produced according to a stochastic Cobb-Douglas production function. The Cobb-Douglas function was chosen because it has a simple formula for the marginal product and has been found to perform well in studies of agricultural production. The statistical...

Provedor de dados: 31
Autores: Kumar,   Shubh K.; Hotchkiss,   David.
In the face of growing concerns about the environment, policy makers in developing countries find themselves increasingly pressured to choose between environmental deterioration in the long run and the growing demands of poor populations in the short run. Some environmentalists point to new technology –irrigation, fertilizer, and pesticides- as the basis of ecological decay in rural areas. A number of studies have shown, instead, that expanding farm yields in less fragile area through modern technology offers a viable alternative to stripping the land to expand crop area in marginal soils. In the hill areas of Nepal, as many developing countries, women’s work is the key not only to the functioning of the household but also a necessary supply of field...

Two-Stage Agricultural Import Demand Models Theory and Applications
Provedor de dados: 31
Autores: Carter,   Colin A.; Green,   Richard D.; Pick,   Daniel H.
The Armington trade model distinguishes commodities by country of origin and import demand is determined in a separable two-step procedure. The Armington framework has been applied to numerous international agricultural markets with the objective of modelling import demand. The purpose of this paper is to test the Armington assumptions of homotheticity and separability with data from the international wheat market. The empirical results overwhelmingly reject these assumptions. This has important implications for international trade modelling.

PROBABILITY DISTRIBUTIONS OF CROP PRICES, YIELDS, AND GROSS REVENUE
Provedor de dados: 31
Autores: Tew,   Bernard V.; Reid,   Donald W.
This study shows that the price-yield correlation is a major influence in determining the skewness of revenue.  Therefore, normality for revenue may not be rejected even if the price and/or yield distributions are significantly skewed.  Analysis of cotton revenue for Mississippi shows that this can be the case empirically when the correlation between price and yield is moderately negative and the relative variability of yield and price is not too high.  Hence, for crops produced in their major production regions where negative correlations between prices and yields are the greatest, revenue distributions may have a greater tendency toward normal.

MACHINERY REPLACEMENT, MULTIPLE OPTIMA, AND THE 1986 TAX REFORM ACT
Provedor de dados: 31
Autores: Lynne,   Gary D.
The 1986 Tax Reform Act established a first year $10,000 expensing option and, for most farm equipment, a 7-year depreciation schedule. Under a profit maximization criterion, these tax law features can lead to multiple optima dependent upon discount and marginal tax rates. For example, the economically efficient time to reinvest under a 2 percent after tax discount rate is at 4, 8, and 30 years for the grower in a 33 percent tax bracket. Thus, the profit maximization behavioral rule needs to be supplemented with knowledge about a farmer's objectives in order to select the "correct" optimal reinvestment interval.

Provedor de dados: 31
Autores: Gerritsen,   Rolf; Abbott,   Jacky.
This article describes the Commonwealth Government's rural policy activities over 1987. In that year, policy was shaped by three interrelated factors: the uneven but marked recovery of commodity prices and the associated diminution of the urgency and political intensity of the "rural crisis"; the Government's survival in the election; and the gradual transformation of policy emphasis from intermittent "political" crisis management towards managerialist and microeconomic efficiency reforms. The intensity of rural politics declined sharply after the election. The amalgamation of the Department of Primary Industry with the Department of Resources and Energy dominated the continued restructuring of rural policy institutions. This restructuring, together with...

Storage, Trade, and Price Policy Under Production Instability: Maize In Kenya
Provedor de dados: 31
Autores: Pinckney,   Thomas C.
Instability in the production of a staple food causes severe hardship for many countries. For a country that is self-sufficient in its staple food in a normal production year, the large swings in price and consumption that result from an exclusive and uninhibited reliance on trade to stabilize prices are unacceptable. Most countries, therefore, intervene in their domestic cereal markets and move supplies from surpluses to deficit years through storage or by subsidizing international trade. The appropriate method of intervention and the most efficient way to achieve supply stability thus became topics of study. For the most part, economist have encouraged governments to rely more on trade than on stocks to make up deficits on years of production shortfalls....

Industrial Concentration in Australian Agribusiness
Provedor de dados: 31
Autores: Vollmers,   A. Clyde.
The structure of agriculture in Australia is experiencing extremely rapid change. Both firms that supply inputs to farmers and firms that process or market farm products are consolidating to create larger organisations. Mergers and acquisitions have enabled some firms to acquire relatively large market shares, thereby dominating portions of the food and fibre sector.  The purpose of this article is twofold: first, it will provide a relatively current description of the concentration within selected subsectors of agribusiness in Australia. Second, it will explore portions of the available literature to determine the impact of consolidations upon profits, operating efficiency, and risk within agribusiness and agriculture. Because concentration is a very...

The results suggest that the districts law is consistent with preserving the best farmland at the rural-urban fringe and that the decision to enroll in agricultural districts affects in a recursive fashion the decision to participate in the use-value assessment program.  Short-term monetary gains are the overriding considerations in applying for use-value exemptions.  This may lead to additional erosion of the tax base via tax preferences for agricultural land.

BROADENING THE CONCEPT AND MEASUREMENTS OF EXISTENCE VALUE
Provedor de dados: 31
Autores: Loomis,   John B.
Recent efforts to refine the concept of existence value and to empirically measure it has led to an unnecessary narrowing of the concept of existence value.  This paper uses the literature on public goods to argue that existence value is a much broader concept than proposed by several authors.  Two commonly used but different empirical approaches to measuring existence values are compared and shown to lead to statistically different decompositions of total value between use and existence categories.

CHOICE OF FLEXIBLE FUNCTIONAL FORMS:  REVIEW AND APPRAISAL
Provedor de dados: 31
Autores: Thompson,   Gary D.
Choice between alternative flexible functional forms has received little explicit treatment in many empirical agricultural studies. Theoretical criteria and empirical techniques for choosing between flexible functional forms are reviewed. Theoretical topics include definitions of flexibility, mathematical expansions, separability, and regular regions. Empirical techniques examined are Monte Carlo analysis, parametric modeling, bayesian inference, and nonnested hypothesis testing. Comparison of the full range of theoretical and empirical aspects may provide more credible and reliable empirical estimates when consumer or producer duality assumptions are appropriate in agricultural applications.

ECONOMIC ANALYSIS OF ON-FARM SOLUTIONS TO DRAINAGE PROBLEMS IN IRRIGATED AGRICULTURE
Provedor de dados: 31
Autores: Dinar,   Ariel; Knapp,   Keith C.
Agricultural production in many semi-arid areas over the world is affected by poor drainage and saline conditions. Optimal agricultural management can be considerably different under these conditions than in locations where these problems do not occur. A long-run steady-state model is developed to analyse several management strategies for a farm with limited natural drainage and no access to off farm facilities. The model is applied to a representative farm in California. Under optimal management, the results suggest relatively small evaporation ponds, a reduction in water application, and little change in cropping patterns. Some drainage reuse is optimal when only variable reuse costs are considered. Returns to land and management are positive in all...

The Place of Expert Systems in Agricultural Economics
Provedor de dados: 31
Autores: Pannell,   David J.
The relevance of expert systems in agricultural economics research and extension is examined. Some of the limitations of existing expert systems are described. Expert systems are useful for storing and retrieving knowledge and for solving diagnostic problems but not for mathematical optimisation. The common method of handling uncertainty in expert systems is shown to have a dubious theoretical basis. Expert systems have no facility for sensitivity analysis. It is concluded that expert systems are unlikely to replace traditional analytical tools for the solution of economic problems but that they may be useful for creation of user-friendly program interfaces.

Bayesian Econometrics and How to Get Rid of Those Wrong Signs
Provedor de dados: 31
Autores: Griffiths,   William E.
In many instances, Bayesian Econometrics offers a more natural interpretation of the results of a statistical investigation than does the sampling theory approach. Furthermore, the Bayesian approach provides a formal framework for incorporating prior information which is frequently available from economic theory. Despite these advantages of the Bayesian approach, applied econometric work has generally been dominated by the sampling theory approach. A simple regression example with one coefficient is used to describe the Bayesian approach using three different priors: a natural conjugate informative prior, a non informative prior, and a prior with inequality restrictions on the sign and possibly magnitude of the coefficient. The differences between the...

Decision-making roles of various levels of management in retail food firms were identified. Particular attention was focused on: (1) identifying the range of responsibility for each level of management, and (2) identifying the degree of involvement for each level of management. A "funneling" effect was depicted in the decision-making process, progressing from general policy decisions by upper level management to more specific operating decisions by store level management.

OPTIMAL REPLACEMENT INTERVAL AND DEPRECIATION METHOD FOR A GRAIN COMBINE
Provedor de dados: 31
Autores: Weersink,   Alfons; Stauber,   Steve.
A stochastic dynamic programming model is developed to determine optimal replacement intervals and depreciation schedules for a combine on a cash grain farm in north central Montana, where the optimal decision is based on the stochastic nature of winter wheat prices. Empirical results indicate that the decision varies widely depending on the states describing the conditions facing the farm firm. Under normal profitable conditions and ERTA81 tax legislation, suggested replacement is after five years of service, the new asset being depreciated under the accelerated cost recovery system and the investment credit option. Changes to the tax law would tend to smooth out and increase this replacement interval.

Supply Response in Broadacre Agriculture
Provedor de dados: 31
Autores: Hall,   Nigel H.; Fraser,   L.; Purtill,   A.
This paper describes a mathematical programming model of broadacre agriculture in Australia and presents estimates of national and regional supply responses made with it. Own-price and cross-price supply elasticities are presented for wool sheep meat, beef and crops and the results compared with those of two other major models of Australian agriculture. It is shown that long term supply responses for the commodities studied are substantially greater than unity as are cross-price elasticities in a number of cases. It is also shown that supply responses differ substantially between regions.

AN ANALYSIS OF MARKET STRUCTURE AND PRICING IN THE FLORIDA CELERY INDUSTRY

Autores: Taylor,   Timothy G.; Kilmer,   Richard L.
The pricing behavior of the Florida celery industry under the current federal marketing order was examined by analyzing the implied market structure of the industry using a model proposed by Appelbaum.  Point estimates of the oligopoly power index suggest that some degree of price enhancement above that which would be characterized by a perfectly competitive market may have occurred.  However, the bulk of statistical evidence suggests that the departure from marginal cost pricing implied by the industry's pricing behavior is not statistically significant.

FACTORS AFFECTING FRESH POTATO PRICE IN SELECTED TERMINAL MARKETS
Provedor de dados: 31
Autores: Goodwin,   Harold L., Jr.; Fuller,   Stephen W.; Capps,   Oral, Jr.; Asgill,   Oladimagi W.
Monthly, quarterly, and annual cross-sectional and time-series data for the period 1982-85 were analyzed to identify factors affecting terminal market price for four types of fresh potatoes. Results indicated that state of origin, terminal market package type, and season of marketing were significant quality variables affecting price. Price differences among potato types because of season of marketing and stocks of fall potatoes were evident. These results suggest that cultivar selection, cultural practices, planting and harvesting schedules, packaging, and market selection – factors which are ultimately controlled by growers and grower/shippers – can be utilized effectively as mechanisms to increase price and expand markets.

Generality of the relationship between attributions and depression across attributional dimensions and across samples
Provedor de dados: 31
Autores: Persons,   Jacqueline B.; Perloff,   Jeffrey M.
Two hypotheses implicit in the use of composite measures of attributions in tests of learned helplessness theory (but not implicit in the theory itself) were tested: the hypotheses that relationships between depression and the three types of attributions are equal in magnitude, and linear. To test these hypotheses, data from three published studies of the reformulated learned helplessness theory of depression (Abramson, Seligman, &amp; Teasdale, 1978) were reanalyzed. The hypothesis that internal, stable, and global attributions are equally related to depression was tested and rejected. Increases in internal attributions were related to depression in one sample: increases in global attributions for negative events were related to depression in two samples:...

THE IMPACTS OF THE CONSERVATION RESERVE PROGRAM ON RURAL COMMUNITIES:  THE CASE OF THREE OREGON COUNTIES
Provedor de dados: 31
Autores: Martin,   Michael V.; Radtke,   Hans; Eleveld,   Bart; Nofziger,   S. Dianne.
Using an economic input/output model, the community personal income impacts of participating in the Conservation Reserve Program were analyzed for three rural Oregon counties. While individual farmers may benefit from participation, there may be net adverse impact on the community if the retired land is relatively productive or if the inputs that are no longer purchased would have been purchased locally. These negative effects may be exacerbated if participating farmers quit farming and leave the local area or if the Conservation Reserve Program benefits go to absentee landowners. The Conservation Reserve Program may then represent a conflict between community and national policy objectives.

FACTOR DEMANDS OF LOUISIANA RICE PRODUCERS: AN ECONOMETRIC INVESTIGATION
Provedor de dados: 31
Autores: McLean-Meyinsse,   Patricia E.; Okunade,   Albert Ade.
A Diewert-flexible (dual) cost function was used to derive a system of conditional factor demand equations for Louisiana rice producers.  Generalized Leontief cost and factor share equations were fitted for the 1955-87 period using Zellner's SURE system estimation procedure.  The Aitken parameter estimates reveal that: (1) the optimal input mix of rice farmers varies with production scale, (2) the factor-augmenting technical change is labor and chemical saving but seed using, (3) pairwise input substitutions are limited, and (4) factor demands are own-price inelastic.  An implication is that Louisiana rice farmers will not appreciably alter their factor utilizations when relative input prices change.

POTENTIAL EFFECTS OF CLIMATE CHANGE ON AGRICULTURE IN THE PRAIRIE REGION OF CANADA
Provedor de dados: 31
Autores: Arthur,   Louise M.; Abizadeh,   Fay.
The objective of this paper is to examine the effects of long-term climate change, as a consequence of doubled atmospheric carbon dioxide, on Canadian prairie agriculture. The climate change scenarios are based on regional results from two leading general circulation models (GCMs), and GFDL model and the GISS model. Although both scenarios suggest that average temperatures will increase in all areas of all three provinces by an annual average of 2.6 to 4.6 degrees centigrade, in some areas additional precipitation is enough to compensate for the increased evapotranspiration. Changes in crop revenues under current economic/technological conditions range from a 7% loss in Alberta under one GFDL scenario to an 8% increase in Saskatchewan under a slight...

Concern over the effects of public policies based on misspecified econometric models motivates interest in a procedure to test, diagnose, and improve the specification of models that have been estimated with three-stage least squares.  A test of system-wide specification based on Hausman's specification test is employed in a test of the a priori restrictions placed on the parameters of a structural model of the U.S. shrimp market.  The null hypothesis of proper specification is rejected.  After diagnosis via a comparison of unrestricted and restricted reduced forms and respecification, the null hypothesis cannot be rejected.

A combination of experimental and simulation procedures identify important factors in an Illinois cash grain farmer’s machinery investment decisions. In an experiment setting, a panel of farmers based investment decisions on their own expectations, farm situations, and varying policy scenarios. In general, the results show investment levels statistically related to the tenure and leverage of operators, the economic conditions they faced, and the age of existing machinery. Alternative public policies of lower commodity price supports, tax reform, and interest rate subsidies influenced the timing of purchases but did not alter total investment amounts.

Autores: Griffin,   Ronald C.; Rister,   M. Edward; Parker,   Michael R.; McCauley,   Garry N.
The economic feasibility of investing in sprinkler irrigation technology for rice production is investigated using linear programming and capital budgeting to identify the net annual benefits and net present value, respectively.  Groundwater and both flat rate and volumetrically priced surface water sources of irrigation water are analyzed.  Under typical practices occurring in rice production operations in the Texas Rice Belt, sprinkler irrigation technology is not profitable at current water costs.  Producers using volumetrically priced surface water have the greatest incentive to consider sprinkler irrigation, but water prices must increase by over 250 percent for the investment in a sprinkler irrigation system to become attractive.  Yield reductions...

The two main objectives of the East Bay Municipal Utility District (EBMUD) water supply management program are to cope with a failure of the aqueducts in the Delta due to earthquake and flood damage and to mitigate periodic shortages. EBMUD emphasizes construction of additional terminal storage, specifically development of a reservoir in Buckhorn Canyon, to meet both objectives. Better alternatives--cheaper and less environmentally damaging--are (to cope with failure) use of existing terminal storage and interties, along with an eventual phased construction of secure aqueducts in tne Delta, and (to mitigate shortages) purchase of high quality Mokelumne River water from the nearby Woodbridge Irrigation District, along with sharply rising block rates to...

Agricultural Economics training is well developed at both undergraduate and postgraduate levels at the University of Queensland. The undergraduate subjects in this discipline are formally listed in the schedules for both the B.Agr.Sc. and the B.Econ. degrees. However, students enrolled for many other degrees (e.g. B.A., B.Com., B.E., B.Sc.) also take agricultural economics subjects as electives. Postgraduate students may enrol for a one year Diploma or two year Masters of Agricultural Studies. These awards are mainly coursework with a short dissertation. The research Masters and Ph.D. degrees have also attracted a significant number of successful candidates.

A CROSS SECTIONAL ANALYSIS OF CONSUMER TRENDS IN RED MEAT CONSUMPTION
Provedor de dados: 31
Autores: Riechers,   Robin; Schupp,   Alvin R.; Dellenbarger,   Lynn E.
Food consumption patterns have received considerable attention lately, especially changes in red meat consumption. This article examines and analyzes changes in meat consumption patterns in a southern state. Differences are reported based on demographics and consumer expressed preferences. The results reaffirm the negative role of health concerns and fat on red meat consumption and the positive influence on poultry and seafood. The findings agree with related other studies and suggest that further research into the changing meat consumption patterns is warranted.

AN EMPIRICAL BAYES APPROACH TO MODELING DROUGHT
Provedor de dados: 31
Autores: Chamberlain,   P.J.
This paper illustrates an alternative approach to estimating the occurrence of drought.  The empirical Bayes methodology was developed because of deficiencies in time-series and regression analysis with respect to prediction of drought.  This manuscript is comprised of (a) a discussion of "classical" and Bayes estimators of probability density (or mass) functions, (b) a description of the model, and (c) a comparison of the performances of the empirical Bayes and two classical estimators in predicting the elapsed time until drought.  The Bayes value (incorporating both a priori and data information) was found to be superior to the traditional estimates.

FARM INCOME ENHANCEMENT POTENTIAL FOR SMALL, PART-TIME FARMING OPERATIONS IN EAST CENTRAL OKLAHOMA
Provedor de dados: 31
Autores: Sanford,   Scott; Tweeten,   Luther G.
Linear programming and stochastic farm growth simulation models are used to assess the impact of alternative enterprise selection, variation in farm income, inflation, and off-farm income on the growth of small, part-time farms in East Central Oklahoma.  Results indicate that alternative rates of inflation or variation in farm income do not significantly impact the operation or expansion of part-time farming operations.  Adoption of alternative enterprises on part-time farms can lead to full-time farming operations where expansion initially is aided through use of off-farm income.  Small full-time operators could greatly enhance family income by obtaining off-farm employment and income.

Autores: Stanbury,   Pamela.
This document is meant to present a framework for analyzing the institutions related to water management in a river basin context. The design of the five-country regional study undertaken by IWMI on “Development of Effective Water Management Institutions” provided a new methodology and a framework for river basin studies. It consists of four key components of diagnostic investigations related to water resources management in a river basin, which are interrelated. These key components are the physical system, water accounting, socioeconomic situation and performance. This study design is given in the Study’s Inception Report of 15 June 1999, and the Methodological Guidelines of 1 October 1999. This document takes one step further, and provides a conceptual...

The Consumption Behaviour of Farmers: a review of the evidence
Provedor de dados: 31
Autores: O'Mara,   L. Paul; Mullen,   John D.; Powell,   Roy A.; Reece,   B.F.
Over recent years there has been marked instability in incomes earned from farming. The instability, which affects the economy generally, is transmitted partly through the consumption spending of farmers. A conventional view of the short-run marginal propensity to consume of farmers, supported by some analyses of aggregate data, is that it is zero. It is argued that this view is implausible on theoretical grounds, that the analysis giving rise to this view used aggregate data which contained serious flaws, and that evidence from micro-studies and other macro level analyses present a more realistic assessment that the short-run mpc of farmers is not zero but likely to be lower than that of non-farmers. A non-zero mpc has implications for how the farm sector...

THE FARM LEVEL EFFECTS OF BETTER ACCESS TO INFORMATION: THE CASE OF DART
Provedor de dados: 31
Autores: Bosch,   Darrell J.; Lee,   Katherine L.
In this study, two methods of entering and accessing dairy herd records are compared: the traditional mail-in Dairy Herd Improvement (DHI) system and the Direct Access to Records by Telephone (DART) system, which provides more timely and convenient access to records.  An evaluation of DART was carried out using mail survey responses from 117 DART users and telephone surveys of 40 randomly selected users.  Results indicate that DART users are generally satisfied with the system and feel that it improves their herd management.  Variations in use of the DART system by DART users are explained by herd, cost, and management variables.  DART users and comparable non-DART, DHI users are compared with respect to gains in herd production efficiency.  Results...

DECISION BASED ECONOMIC THEORY
Provedor de dados: 31
Autores: Oskam,   Arie J.
Decision based economic theory stresses the central position of the objective function in the behavior of economic agents.  Insufficient knowledge of objective functions hampers the development of economic theory.  In this article, a methodology for deriving objective functions from conscious decisions has been developed.  Three categories of decisions are concerned: positive, negative, and mutually exclusive decisions.  Assuming minimal inconsistency, the objective function can be derived by means of linear or nonlinear programming and using a revealed preference approach.  The method has been applied to derive the linear objective function of EC dairy policy.  However, applications of this methodology for consumers and producers are similar.  A number of...

NON-FARM LABOR SUPPLY: THEORY AND ESTIMATION
Provedor de dados: 31
Autores: Gebauer,   Rolf H.
During the last decade considerable research has been carried out on the non-farm labor supply of farm households. New insights and hypotheses on the economic behavior of households, known as "new home economics," and progress in applying more sophisticated estimation techniques have stimulated these research activities.  The focus of this paper is the standard neoclassical model of labor supply and a corresponding empirical research strategy.  The empirical model refers to household-level data from West Germany.  As the results reveal, farm households decide on the allocation of their resources in a very rational manner.  This shows their high capacity and flexibility to adjust to varying economic circumstances.

MEASURING THE COMPONENTS OF AGGREGATE PRODUCTIVITY GROWTH IN U.S. AGRICULTURE
Provedor de dados: 31
Autores: Capalbo,   Susan Marie.
A method of decomposing the growth in total factor productivity into effects due to nonconstant returns to scale and technical change was applied to the U.S. agricultural sector. The scale effects and technical changes were measured using an economically estimated two-output, three-input translog cost model. Total factor productivity as conventionally measured grew at an average annual rate of 1.56% from 1950-82. This growth rate, however, misrepresented the rate of technical change in U.S. agriculture primarily due to the nonconstant scales effects.

A Comparison of Tariffs and Quotas in a Strategic Setting
Provedor de dados: 31
Autores: Karp,   Larry S.
We model the situation where two large countries impose either tariffs or quotas and a third large country remains passive. The introduction of the third country overturns results from two-country models. Stable quota equilibria are capable of reproducing the equilibrium price under tariffs, and Nash equilibria with quotas can result in positive amounts of trade. Using a linear partial equilibrium model, we show that world welfare may be higher under Nash quotas than under Nash tariffs. However, simulation results suggest that tariffs are likely to result in higher welfare than quotas.

QUALITY RESTRICTIONS AS BARRIERS TO TRADE:  THE CASE OF EUROPEAN COMMUNITY REGULATIONS ON THE USE OF HORMONES
Provedor de dados: 31
Autores: Peterson,   E. Wesley F.; Paggi,   Mechel S.; Henry,   Guy.
Sanitary regulations, product definitions, grades, production or processing regulations, and other qualitative standards are generally applied to both domestic production and imported goods.  These quality restrictions can be seen as trade barriers, although it is often difficult to determine whether a given restriction is based on legitimate health or safety concerns or is simply an alternative device for protecting producers.  The purpose of this paper is to evaluate the welfare effects of a recent quality regulation, the European Community ban on the use of hormones in livestock production.  A conceptual framework is developed to analyze the effects of the ban on the market for edible offals.  The results indicate that Community prices for edible offals...

THE RELATIVE SIGNIFICANCE OF A RANGE OF ECONOMIC POLICIES FOR IMPROVING AUSTRALIA'S BALANCE OF TRADE
Provedor de dados: 31
Autores: Stoeckel,   Andrew B.; Higgs,   Peter J.
Australia faces a very serious trade problem. A large improvement in the balance of trade is required simply to stop its international debt from rising above levels which are already considered too high. In this paper, a range of economic policies are examined. Each generates a $A1 billion improvement (in 1985-86 prices) in the balance of trade after about 2 years. The following economic shocks are examined: an increase in world agricultural prices; a cut in real wages; a reduction in protection for manufacturing industries; a change in the tax mix in favour of indirect taxation; and a contraction in real domestic absorption. The impacts of these shocks are derived from simulations with ORANI, a computable general equilibrium model of the Australian...

Autores: Brorsen,   B. Wade; Grant,   Warren R.; Rister,   M. Edward.
Quality discounts and premiums for rough rice in Texas rice bid/acceptance markets are analyzed. The most important quality factors determining the value of rough rice are head yield and peck. A one percentage point reduction in peck damage raises the price received per hundredweight of rough rice by $.13 to $.68 across markets and years. Since peck damage can be reduced by controlling the rice stinkbug, evaluation of alternative methods for better control of this pest in Texas rice fields is needed.

An Evaluation of Equity Redemption Alternatives in Centralized Cooperatives
Provedor de dados: 31
Autores: Barton,   David G.; Schmidt,   Royce L.
Evaluations of five basic equity redemption alternatives are made for the distinct patron-cooperative economic relationship found in both regional and local centralized cooperatives. The five alternatives are the estate settlement, age-of-patron, revolving fund, percentage pool, and base capital plans. An empirically estimated economic life cycle is used to determine the pattern of patronage and investment by patrons. Redemptions are determined for several programs, each using estate settlement alone or in combination with another plan. Performance is measured using three criteria: flexibility, proportionality, and cash flow. Results vary significantly among alternatives.

Questionnaire surveys are an established economic research method for eliciting consumers' surplus values. However, the necessarily hypothetical nature of surveys may not promote truthful responses. In 17 empirical tests, actual money donations were elicited and compared to hypothetical donations elicited previously. In all 17, there was no statistical difference between the actual and hypothetical willingness to pay. Hypothetical bias was therefore absent in all these tests.

The economic impact of some future biological nitrogen fixation technologies are estimated using AGSIM, a dynamic, partial equilibrium, econometric model of the U.S. agricultural sector. Five separate scenarios were modeled: (1) legumes fix more nitrogen, (2) legumes fix more nitrogen with an increase in legumes yields of 10 percent, (3) nitrogen fertilization requirements on all crops are reduced 50 percent with no yield changes, (4) total elimination of nitrogen fertilization and (5) total elimination of nitrogen fertilization and non-legume yields decrease 10 percent. Results indicate that biological nitrogen fixation technologies have a high value to society. Increasing the efficiency of legumes to fix nitrogen may have an annual benefit of $1,067...

AN ANNUAL MODEL OF PUREBRED BREEDING BULL PRICE
Provedor de dados: 31
Autores: Greer,   R. Clyde; Urick,   J.J.
A geometric distributed lag model was hypothesized as the structural relationship between purebred breeding bull price and economic variables determining the bull’s value as a productive asset. Parameter estimates for the nonstochastic difference equation were obtained from a data sample including nineteen years of average price paid for yearling purebred Hereford bulls. Statistical results supported the hypotheses; expected bull price was responsive to calf price and cowherd inventory. An oscillating geometric adjustment pattern was found which reflected periodicity in bull replacement decisions. The general conclusion was that relevant information is rapidly incorporated into purebred bull market behavior and price adjusts quickly.

ACCUMULATION AND RENTAL BEHAVIOR IN THE MARKET FOR FARMLAND
Provedor de dados: 31
Autores: Chambers,   Robert G.; Phipps,   Tim T.
A farmer’s choices of tenure and farm size result from a complex interplay of economic factors technology, entrepreneurial ability, and personal preferences. This paper examines the qualitative effects of these factors on tenure and farm size in a dynamic optimization framework. One implication of the theoretical model is that changes in technology should cause systematic differences to be observed between rates of return on farmland and rates earned on comparable long-term assets. This implication is supported by an empirical test.

The sensitivity of regional industry to business cycles has been widely documented.  Responses of individual businesses and industries in a specific region or state to each phase of the business cycle has been less well analyzed and understood.   Lacking in all the documentation, moreover, is reference to the impact of business cycles on interregional trade and regional interindustry structure and to the separation of these impacts from those due to business activity location and dislocation.  To deal with these limitations, state-level location quotient and shift-share analyses of year-to-year changes in industry-specific contribution to gross state product are used in differentiating the varying degrees of cyclical sensitivity among industries and...

THE BUFFER ROLE OF GROUNDWATER WHEN SURFACE WATER SUPPLIES ARE UNCERTAIN: THE IMPLICATIONS FOR GROUNDWATER DEVELOPMENT
Provedor de dados: 31
Autores: Tsur,   Yacov.
When used in conjunction with surface water for irrigation, groundwater serves two roles: to increase water supply; and to mitigate fluctuations in the supply of water.  The later is the buffer role.  This paper identifies and evaluates the economic benefit associated with the buffer role of ground water.  Implications for the development of groundwater resources are investigated.  An estimate is given of the buffer benefit to wheat growers of the fossil water aquifer underlying the Israeli Negev.  It is found that, under the prevailing variability in the supply of surface water, this benefit may well exceed the groundwater benefit associated with the increase in water supply.

Developing Country Agriculture in the Uruguay Round: What the North Might Miss
Provedor de dados: 31
Autores: Mabbs-Zeno,   Carl C.; Ballenger,   Nicole.
The Uruguay Round of negotiations under the General Agreement on Tariffs and Trade (GATT) may draw agriculture into an unprecedented global liberalization process. If developed nations write the agenda for these negotiations and direct the research on economic effects of liberalization, they are likely to underplay several impacts which fall primarily on LDC's. This paper identifies several ways in which the history, structure, or economic power of LDC's precipitate different consequences from liberalization than would arise in developed nations. These points ought to be recognized at the GATT both because the negotiations will affect their resolution and because they will affect the coalitions and compromises LDC's bring to the GATT.

RECENT CHANGES IN THE REGIONAL STRUCTURE OF U.S. DAIRY PRODUCTION
Provedor de dados: 31
Autores: Huy,   Birgit; Elterich,   Joachim G.; Gempesaw,   Conrado M., II.
Gauging the impact of recent policy changes, this article analyzes production characteristics and the impact of the dairy assessment for northeastern dairy farmers as compared to other major production regions.  Employing a restricted translog variable profit function, returns to size, shadow prices, supply elasticities for milk and livestock as well as demand elasticities for concentrate were estimated.  Northeastern, just as Midwestern farmers, were less responsive in milk supply and concentrate demand, more responsive in livestock production, and less efficient than their California and Texas counterparts.  The dairy assessment affected profits of northeastern farmers later than those of other regions.  Negative shadow prices indicated overinvestment...

Producer Price Equalization
Provedor de dados: 31
Autores: Alston,   Julian M.; Freebairn,   John W.
Most previous studies of home consumption pricing and producer price equalisation schemes have concentrated on static economic surplus effects under an assumption of a perfectly elastic export demand. This paper compares the effects of different types of producer price equalisation schemes with free trade in the wheat, milk and egg industries allowing for a downward sloping export demand. Average values and variances of prices, quantities, revenues, and economic surplus measures are estimated for each policy in a simulation model allowing a range of values for elasticities of supply and demand, market shares, and variability of supply and export demand. The stabilisation effects of equalisation schemes are evaluated using these estimates.

IRRIGATED AGRICULTURE ON THE HIGH PLAINS:  AN UNCERTAIN FUTURE
Provedor de dados: 31
Autores: Mapp,   Harry P., Jr.
Recent declines in irrigated acres in the High Plains and shifts to crops which use less water are likely to continue, with an eventual return to dryland production in many regions. Declining groundwater levels and depletion of the Ogallala aquifer are secondary causes of this decline. Primary causes are high irrigation costs and low profitability of irrigated crops relative to dryland crops produced within and outside the region. Continued low commodity prices will speed the transition to dryland production as many current irrigators are unable to replace fully depreciated irrigation systems. Adoption of new technology will slow but not reverse the reduction in irrigated production.

An Integrated Package for Linear Programming
Provedor de dados: 31
Autores: Pannell,   David J.
Batterham (1987) described a computer program which eases entry of mathematical programming data. Users of the program first use a text editor to enter data in a relatively efficient format, which the program then converts into MPS format as required by most mathematical programming solution programs. Alternatively the program can read and convert data from a microcomputer spreadsheet data file.  This note is a description of a microcomputer program which has advantages over each of these procedures. The program, GULP (General, User friendly Linear Programming), is an integrated package of procedures for data entry, matrix printing and model solution. GULP has particular advantages for education and has been used in a number of courses in Western Australia.

Supply and Demand Interactions in the New South Wales Prime Lamb Market
Provedor de dados: 31
Autores: Vere,   David T.; Griffith,   Garry R.
Prime lamb has not received the same level of economic research as Australia's other major livestock markets and knowledge of the lamb market's operations remains relatively limited. This market has experienced increasing problems including highly variable saleyard prices, strong retail competition and calls for market reform. To date, there has been no quantitative mechanism for assessing the potential impacts of these issues on the state or national lamb markets. This paper reports the development of a quarterly econometric model of the New South Wales prime lamb market. The model considers prime lamb as a separate market entity and places emphasis on the demographic influences on supply response. The estimated model is validated under historical dynamic...

Adjusting prices for volume: a test of the Hotelling valuation principle
Provedor de dados: 31
Autores: Berck,   Peter.
This paper tests the hypothesis that the net of extraction cost price of a natural resource does not change with volume. The hypothesis is shown to he a consequence of Hotelling’s theory. The tests are performed on equations estimated by a nonparametric regression (ACE), and we show that the usual least squares estimation techniques are not general enough to successfully perform the test. The test rejects the pure form of the Hotelling theory and shows that it is  necessary to adjust sale prices for volume sold.

Existence of Equilibria in Lobbying Economics
Provedor de dados: 31
Autores: Coggins,   Jay S.; Graham-Tomasi,   Theodore; Roe,   Terry L.
Governments often establish economic policy in response to political pressure by interest groups. Since these groups' political activities may alter prices, economies so affected cannot be characterized by perfect competition. We develop a model of a "lobbying economy" in which consumers' choice of political activity simultaneously determines relative prices and income levels. They balance the loss in income due to lobbying payments against the potential gain in wealth from a favorable government price policy. This paper proves the existence of an equilibrium in economies of this sort. We reformulate the economy as a generalized lobbying game and prove the existence of a non-cooperative equilibrium in the game. This equilibrium is then shown to be an...

A NONPARAMETRIC ANALYSIS OF CONSUMER PREFERENCES FOR FRESH MEAT PRODUCTS
Provedor de dados: 31
Autores: Moen,   Daniel S.; Capps,   Oral, Jr.
Nonparametric statistical methods (the Kruskal-Wallis test and Dunn's multiple comparison procedure) were used to analyze consumer preferences for fresh meat products (chicken, beef steak, beef roast, fish, ground beef, pork, turkey, and lamb) in a retail food chain in Houston. On a pairwise basis, significant differences in ratings were evident for the majority of the fresh meat products in terms of frequency of purchase as well as taste and quality. In particular, chicken was not only the most frequently purchased fresh meat product but also compared favorably to all meat items in terms of taste and quality.

A FARM-LEVEL ANALYSIS OF SOIL LOSS CONTROL: MODELING THE PROBABILISTIC NATURE OF ANNUAL SOIL LOSS
Provedor de dados: 31
Autores: McSweeny,   William T.
The Conservation Compliance provision of the Food Security Act of 1985 requires all farmers who farmed highly erodible land prior to the passage of the Act to have a locally approved conservation plan fully implemented by 1995 or lose eligibility for numerous farm programs.  Soil loss estimates of various crop, tillage practices, and conservation practices, however, are stochastic in nature.  A farm planning model is suggested that allows for stochastic soil loss estimates.  The model is compared to other models used in farm level soil conservation studies.  The model shows promise as a more acceptable tool in that the farm plans are more likely to be acceptable to the farmer.

A conceptual link among mean-variance (EV), stochastic dominance (SD), and mean-risk (ET), and Gini mean difference (EG) is established for determining risk efficient decision sets. The theoretical relations among the various efficiency criteria are then empirically demonstrated with a soybean and wheat double-crop simulation model. Empirical results associated with extended Gini mean difference (EEG) and extended mean-absolute Gini (EET) for risk analysis are encouraging.

REGIONAL SHRIMP MARKET RESPONSES TO DOMESTIC LANDINGS AND IMPORTS
Provedor de dados: 31
Autores: Houston,   Jack E.; Nieto,   Amelia E.
U.S. shrimp landings are divided into four geographic regional markets and may be further subdivided into species and size characteristics.  Seemingly unrelated regressions were used to analyze regional price responses of variable annual landings of shrimp.  The contemporaneous correlation of competing market supplies and demands accounted for an improvement in forecasting reliability in each area and for species and size relationships.  Imports were shown to affect regional markets unevenly, having a significantly higher impact on South Atlantic shrimp prices than on Gulf of Mexico, West Coast, or New England markets.  Real disposable personal income affected West Coast and South Atlantic prices much more dramatically than those of Gulf Coast markets....

Changing Variability in Cereal Production in Australia
Provedor de dados: 31
Autores: Anderson,   Jock R.; Dillon,   John L.; Hazell,   Peter B.R.; Cowie,   A.J.; Wan,   G.H.
As part of a review of changing patterns of variability in cereal production around the world, the situation in Australia is examined both by major cereal crops and by State in which they are grown. The Australian results are generally consistent with those found in parts of both the industrial and developing world. There has been a tendency for production and especially yields to become both somewhat more variable as assessed by the dimension-free measure, the coefficient of variation, and more covariate between producing regions. The two post-World War II sub-periods examined are dominated, respectively, by tall (traditional) and short (modern) cultivars suggesting that there may be a causal link between cultivar used and relative yield variability.

TAXATION, COST OF CAPITAL AND INVESTMENT IN AUSTRALIAN AGRICULTURE
Provedor de dados: 31
Autores: Lewis,   Philip E.T.; Hall,   Nigel H.; Savage,   C.R.; Kingston,   A.G.
The concept and measurement of the cost of capital is developed to include particularly the role of taxation in investment behaviour. The relative importance of factors influencing investment in plant and machinery is examined for five sectors which make up the broadacre industry of Australia. It is shown that residual funds are important in determining plant and machinery investment, but not through the normally hypothesised channels. It is not the increased liquidity from increased income which raises investment, but the fall in the cost of capital, which is associated with the marginal rate of tax.

Irrigation, under conditions where water has a high opportunity cost, could be interruptible with water use, only occurring when water is plentiful. Pacific Northwest case studies indicate interruption can substantially lessen the opportunity cost of new irrigation developments, although not enough to justify the particular case projects examined. Interruptible operation of existing projects in the case study areas appears desirable.

Relationship of Pooling to Equity Capital and Current Assets of Large Producer Marketing Cooperatives
Provedor de dados: 31
Autores: Sporleder,   Thomas L.; Malick,   William M.; Tough,   Cynthia H.
Committed marketing cooperatives have ensured member support and because of pooling may have higher leverage relative to buy-sell cooperatives. The hypothesis tested in this article is that marketing cooperatives with pooling have less market risk compared with those without pools and as a consequence can incur more financial risk and command greater leverage. Using an econometric approach to control for size of cooperative, empirical results suggest that pooling cooperatives have increased leverage, about 9 percent more than nonpooling cooperatives.

FINANCIAL PERFORMANCE IN MEAT AND POULTRY MANUFACTURING AND WHOLESALING: AN HISTORICAL PERSPECTIVE
Provedor de dados: 31
Autores: Hudson,   Michael A.; Hughes,   Matthew W.; Lins,   David A.
The financial performance of meat and poultry manufacturing and wholesaling firms is examined for the period from 1970 to 1986. Measures of liquidity, solvency, profitability, cash generation, and efficiency reported in the Robert Morris Associates Annual Statement Studies are used to examine relative performance across the different industries. The results suggest a similar performance in the wholesaling and manufacturing industries across the period in terms of liquidity. Profitability levels are similar for meat and poultry firms, although the poultry firms show a higher level of variability across the period. It appears that poultry firms leveraged themselves relatively more than did meat firms during the period. In terms of cash generation and...

Socioeconomic and Technical Characteristics of New England Dairy Cooperative Members and Nonmembers
Provedor de dados: 31
Autores: Bravo-Ureta,   Boris E.; Lee,   Tsoung-Chao.
This paper compares socioeconomic and technical characteristics of dairy cooperative members and nonmembers based on a sample of New England dairy herd improvement association participants. Descriptive statistics indicate there is a little difference between the two groups. A high proportion of members stated cooperatives were helpful primarily because they provide a safe or guaranteed market. Estimates of a Cobb0Douglas production function suggest membership in one specific cooperative was positively and significantly associated with average farm efficiency. Results of a logit analysis indicate the probability of being a cooperative member was positively related to extension contracts and negatively related to output per cow per farm.

Outlook for Interest Rates and the Exchange Rate
Provedor de dados: 31
Autores: Argy,   Fred.
The theme of my paper is that, provided the terms of trade remain fairly stable, a real exchange rate at about its average 1986-87 level is consistent with a stabilisation of our external debt in 1991; and that the necessary turn-around in our trade balance can occur without requiring a marked slowing down in economic growth. The paper also argues that, if markets accept this view, interest rates will be able to sustain their recent decline.

CHANGING CONDITIONS AND EMERGING ISSUES FOR AGRICULTURAL PRODUCTION IN THE NORTHEAST
Provedor de dados: 31
Autores: White,   Gerald B.
Production agriculture in the Northeast represents a declining share of national agricultural production.  Some of the characteristics of Northeast agriculture that affect its future are (1) an unfavorable resource base; (2) proximity to population centers; and (3) a diversity of enterprises.  Major issues affecting the future include changing technology, changing structure, competitive advantage, regulation, and labor supply and demand.  The role of specialty crops in Northeast agriculture was examined.  Pesticide regulation and the labor requirement for specialty crops are serious constraints to widespread adoption.

MODELING ANIMAL AND FORAGE RESPONSE TO FERTILIZATION OF ANNUAL RANGELANDS
Provedor de dados: 31
Autores: Olson,   Kent D.; Mikesell,   Chris L.; Raguse,   Charles A.; George,   Melvin R.; Taggard,   Ken L.
The response functions for forage, animal gain, and stocking rate were estimated from data obtained in a three-year fertilization experiment on California annual range.  Degree-days; the interactions between degree-days and nitrogen, between degree-days and phosphorus-sulphur, and between nitrogen and phosphorus-sulphur; and the lagged forage variable were significant in explaining the variations in forage growth, animal gain, and stocking rate.  The impact of PS was more important in interaction with DD or N than by itself.  The correct impact of moisture was not found due to misspecification of the variable in the model.  The models for the first year and the three years combined were well behaved; however, the models for the last two years combined...

ALLOCATION OF GENERIC ADVERTISING FUNDS AMONG PRODUCTS: A SALES MAXIMIZATION APPROACH
Provedor de dados: 31
Autores: Kinnucan,   Henry W.; Forker,   Olan D.
With the passage of the Dairy and Tobacco Adjustment Act of 1983, dairy farmer investment in product research, nutrition education, advertising, and promotion in the United States increased from $60 million to $200 million annually.  A key decision faced by boards managing these funds is how best to allocate available advertising funds among the various dairy products.  In this paper an economic model is developed that shows the allocation of funds among products that would maximize sales in a given market.  The model is applied to the New York City market with results suggesting that over the study period diverting funds from fluid milk to cheese advertising would have enhanced milk-equivalent sales in the market by as much as 1.17% or 8.21 million...

UNCERTAIN RECREATION QUALITY AND WILDLIFE VALUATION:  ARE CONVENTIONAL BENEFIT MEASURES ADEQUATE?
Provedor de dados: 31
Autores: Cory,   Dennis C.; Colby,   Bonnie G.; Carpenter,   Edwin H.
Theoretical issues and empirical approaches are discussed for benefit estimation when wildlife resource users face uncertain recreation quality. It is argued that selection of an appropriate benefit measure is predicted upon differing attitudes toward quality uncertainty, expected utility maximization, and risk. In particular, it is shown that for specific groups in the user population, conventional benefit measures do not apply, and alternative welfare measures are developed. Implications for restructuring contingent valuation procedures are discussed.

Recent Changes in EC Agricultural Policy: a 1987-88 policy review
Provedor de dados: 31
Autores: Manegold,   Dirk.
New provisions for improved management of price and market policy, implementation of supplementary programs of alleged supply control, and procurement of additional financial resources have. during the last 12 months, deeply affected EC agricultural policy. The present policy is briefly reviewed, highlighting these developments and suggesting likely consequences. The state of information being 1 May 1988, the latest revision of EC agricultural prices (1988-89 marketing year) is dealt with on the basis of the first draft of the Commission's annual price package.

Some Comparisons of Recent Estimates of Agricultural Supply Elasticities for the Australian Economy
Provedor de dados: 31
Autores: Adams,   Philip D.
An accurate knowledge of the supply responsiveness of agricultural exporting industries is crucial if sensible judgements are to be made about diverse policy initiatives, including initiatives having no obvious connection with agriculture. In this paper we compare some recent estimates of short-run supply elasticities for agricultural commodities in the Australian economy. Our attention is focussed particularly on the different types of production technologies and econometric methods used to derive values for these elasticities.

INPUT SUBSTITUTION IN IRRIGATED AGRICULTURE IN THE HIGH PLAINS OF TEXAS, 1970-80
Provedor de dados: 31
Autores: Nieswiadomy,   Michael L.
The adaptability of irrigated agriculture in the High Plains region of Texas in the 1970-80 period is analyzed by estimating Allen partial elasticities of substitution for five key inputs (water, labor, center pivot, furrow and wheel roll systems) used to produce two crops (cotton and grain sorghum). The results indicate that farmers have adapted to changes in a manner generally consistent with prior expectations concerning complementarity  and substitutability among inputs. The output–constant price elasticities of water demand was statistically significant but relatively small (-25).

The total food industry system in the United States is visualized as a nationwide network linking major market area components (products, consumption and structure) to major systems components (e.g. information systems, financial structure, transport and legal-regulatory) for the major market areas of the country. Emphasis is placed on identification and measurement of the linkages and relationships between and among this myriad of system components. A cooperative national effort is urged to model the system for measurement and evaluation of current and future food systems.

This document is meant to present a framework for analyzing the institutions related to water management in a river basin context. The design of the five-country regional study undertaken by IWMI on “Development of Effective Water Management Institutions” provided a new methodology and a framework for river basin studies. It consists of four key components of diagnostic investigations related to water resources management in a river basin, which are interrelated. These key components are the physical system, water accounting, socioeconomic situation and performance. This study design is given in the Study’s Inception Report of 15 June 1999, and the Methodological Guidelines of 1 October 1999. This document takes one step further, and provides a conceptual...

IMPLICATIONS OF GLOBAL CLIMATE CHANGE FOR WESTERN AGRICULTURE
Provedor de dados: 31
Autores: Adams,   Richard M.; McCarl,   Bruce A.; Dudek,   Daniel J.; Glyer,   J. David.
Global climate change from increases in atmospheric carbon dioxide and other trace gases is an issue of international concern. Adverse climate conditions are expected to reduce crop yields and alter the demand for and supply of water. These potential adjustments imply economic costs to agriculture and its constituents. This paper explores possible economic implications for U.S. agriculture, with particular reference to the West. Results from a series of spatial equilibrium model analyses suggest that climate change is not a food security issue for the United States. However, regional adjustments in agricultural production and associated resource use are expected. This implies additional pressure in rural communities. Environmental quality reductions are...

OBTAINING LOWER AND UPPER BOUNDS ON THE VALUE OF SEASONAL CLIMATE FORECASTS AS A FUNCTION OF RISK PREFERENCES
Provedor de dados: 31
Autores: Mjelde,   James W.; Cochran,   Mark J.
A methodological approach to obtain bounds on the value of information based on an inexact representation of the decision maker’s utility function is presented. Stochastic dominance procedures are used to derive the bounds. These bounds provide more information than the single point estimates associated with traditional decision analysis approach to valuing information, in that classes of utility functions can be considered instead of one specific utility function. Empirical results for valuing seasonal climate forecasts illustrate that the type of management strategy given by the decision maker’s prior knowledge interacts with the decision maker’s risk preferences to determine the bounds.

Pricing of Queensland Sugar Cane: Appraisal of the Present Formula and a Suggestion for Reform
Provedor de dados: 31
Autores: Dixon,   Peter B.; Johnson,   David T.
Production and milling of sugar cane in Queensland occur in a highly regulated environment. In particular the price of cane is determined by a formula which has been used virtually unchanged for about 70 years. Under this formula, the returns to millers are tied to the price of sugar, not the costs of milling. It is argued in the paper that this could lead to economically unjustified changes in milling arrangements and wasteful uses of milling resources. Other weaknesses of the present formula are also identified. An alternative formula, overcoming all identified problems, is suggested.

As the Central Arizona project is being completed and contracts are being negotiated, economic analysis continues to show that neither agriculture nor municipalities would benefit from the project if repayment actually is required according to previously suggested schedules.  Earlier analyses were either ignored or condemned as farmers were willing to play a water development game in the face of uncertain future repayment requirements.  The game of playing for subsidized water continues even as the buyers now face real costs rather than just some future possibility of incurring costs.  Recent analysis is being used to help negotiate favorable delivery and repayment contracts.  Experience has shown that once the physical development is in place, costs are...

The Role of Cooperatives in Agriculture: Historic Remnant or Viable Membership Organization?

Autores: Centner,   Terence J.
Although cooperatives offer a viable organizational structure for many groups, economic theory suggests that the cooperative form of business should be preferred over a corporation only if special conditions are present. This paper identifies several conditions that may serve as justifications for cooperatives. Next, conditions limiting the performance of cooperatives are examined. Cooperative members are urged to examine their organization to discern whether its organizational structure provides the best vehicle for meeting group objectives.

Targeted and Global Export Subsidies and Welfare Impacts
Provedor de dados: 31
Autores: Bohman,   Mary; Carter,   Colin A.; Dorfman,   Jeffrey H.
A three-country model of export subsidies is developed with an exporter, an importer, and a third country, representing the rest of the world, that can act on either side of the market. The welfare effect of an export subsidy targeted toward one importing country is shown to depend on whether the third country is an exporter or an importer, the market shares, and demand elasticities. The possibility of the paradoxical result that the targeted country can lose welfare as a result of receiving a subsidy is demonstrated to exist, and conditions are derived that determine when this result occurs. It is also demonstrated that when the rest of the world is a net exporter, a country offering a targeted export subsidy will suffer a welfare loss, while either its...

TOWARD A GLOBAL AGRICULTURAL SYSTEM
Provedor de dados: 31
Autores: Ruttan,   Vernon W.; von Witzke,   Harald.
Since World War II barriers to international trade in industrial commodities have been reduced while barriers to agricultural commodity trade have become more severe.  During the last several decades the world has experienced cycles of "food pessimism" and "food optimism."  Nevertheless, as a result of technical change the terms at which the world's consumers can expect to have access to food appears to be more favorable in the future than in the past.  If consumers are to have access to the greater abundance that can be made available, it will be necessary for developed market economies to reduce the distortions resulting from agricultural commodity and trade policies.  It is in the interest of both producers and consumers, in developed and developing...

Determinants of the U.S. Wheat Producer Support Price: A Time Series Analysis
Provedor de dados: 31
Autores: von Witzke,   Harald.
Public choice in agriculture is an emerging field in agricultural economic research. The paper's focus is on the determinants of the U.S. wheat producer support price. The econometric time-series analysis suggests that this price is largely determined by the previous price, the expected U.S. share in world exports, and expected program costs. Presidential elections also influence U.S. wheat price policies. All other things being equal, the support price tends to be lower in election years than in other years. This suggests that small interest groups' relative political economic power may be smaller in election years if they do not succeed in positioning themselves on the political economic market such that they contain the potentially decisive voter.

TESTING FOR DIFFERENCES IN CONSUMER ACCEPTANCE OF IDENTICALLY APPEARING POTATO VARIETIES
Provedor de dados: 31
Autores: Kezis,   Alan S.; Smith,   Duane A.; Peavey,   Stephanie R.; Lloyd,   Joseph A.
Like many other vegetables, potatoes are marketed by type (russet, round white, red), rather than by variety (Burbak, Katahdin, Pontiac). Although varieties of the same type have similar outward appearances, they are also known to have different internal and cooking characteristics.  There has been considerable controversy over the need for variety identification promotion in the potato industry. A consumer response study that distinguished between user satisfaction with different potato varieties was viewed as a step toward resolving this issue.

A MARKOV CHAIN ANALYSIS OF PORK FARM SIZE DISTRIBUTIONS IN THE SOUTH
Provedor de dados: 31
Autores: Disney,   W. Terry; Duffy,   Patricia A.; Hardy,   William E., Jr.
Concerns over declining farm numbers, shifts in farm size distribution, and associated infrastructural problems have led to a heightened awareness of structural considerations within policy making circles.  Future policy decisions will have substantial structural consequences for the agricultural industry.  Often, however, the indirect effects of grain pricing policies on the livestock sector have been overlooked in these policy decisions.  The incorporation of price effects into a Markov chain analysis of pork farm size distributions and the simulation of those projections to the year 2000 under various price scenarios should provide some insight into the future structure of livestock farming in the South.

FORECASTING AGRICULTURAL PRICES USING A BAYESIAN COMPOSITE APPROACH
Provedor de dados: 31
Autores: McIntosh,   Christopher S.; Bessler,   David A.
Forecast users and market analysts need quality forecast information to improve their decision-making abilities.  When more than one forecast is available, the analyst can improve forecast accuracy by using a composite forecast.  One of several approaches to forming composite forecasts is a Bayesian approach using matrix beta priors.  This paper explains the matrix beta approach and applies it to three individual forecasts of U.S. hog prices.  The Bayesian composite forecast is evaluated relative to composites made from simple averages, restricted least squares, and an adaptive weighting technique.

Comment

Autores: Simmons,   Phil.
From my experience as a manager of economic research I believe that tertiary agricultural economics education has two major shortcomings. First, a large proportion of new graduates have poor writing skills. Their problems in this area revolve around ignorance of elementary grammar and lack of precision in written expression. The second problem that I perceive is that a significant proportion of economics graduates appear to lack any knowledge of economics. These individuals should have been failed from programs yet somehow have managed to get degrees.

A production frontier methodology is used to measure the overall efficiency of a sample of farms obtaining credit from the Farmers Home Administration (FmHA) compared to nonparticipants.  The study did not find evidence that the efficiency of FmHA farms improved between 1981 and 1984.  Results indicate that the overall efficiency of FmHA borrowers is associated with selected financial characteristics of the farms.

A Monte Carlo investigation is used to examine the performance of two commonly used tests for Granger causality for univariate and bivariate nonstationary ARMA (p,q) processes. Tests are applied to raw data, first differences of the raw data, and detrended versions of the series. The results indicate that for independent series the tests are robust regardless of sample size. With bivariate series and nonstationarity, the tests results are sensitive to the ARMA specification, whether the data are filtered and the type of filter used, and the sample size.

DIRECT PRODUCT PROFIT: A VIEW FROM THE SUPERMARKET INDUSTRY
Provedor de dados: 31
Autores: Stoops,   Glenn T.; Pearson,   Michael M.
Direct Product Profit (DPP) is a decision making tool that helps the food merchandiser by providing a better indication of the profitability of products on the supermarket shelves. Direct Product Profit allocates Direct Product Costs (DPC) to individual products. These DPCs are subtracted from gross margin to derive DPP. This paper reports on the use of DPP in the syrup product section of a chain of supermarkets. Implications for managerial action are also discussed.

FACTORS AFFECTING WELFARE GAINS FROM FISHING GEAR RESTRICTIONS
Provedor de dados: 31
Autores: Anderson,   Eric E.
While the use of gear restrictions to regulate fishing activity seldom has the objective of improving economic efficiency, it is capable of achieving that result under some conditions.  It can also reduce economic efficiency.  This paper explores the way several factors affect the sign and magnitude of welfare gains from fishing gear restrictions.  These factors include, among others: the fixity or variability of the price of fish and the presence or absence of diminishing short-run average product of effort.  Some generalizations are offered regarding the characteristics of fisheries in which gear restrictions are most likely to produce welfare gains.

INDUSTRIAL DIVERSIFICATION IN NONMETROPOLITAN COUNTIES AND ITS EFFECT ON ECONOMIC STABILITY
Provedor de dados: 31
Autores: Smith,   Stephen M.; Gibson,   Cosette M.
Applying indexes of economic instability and industrial diversification to Idaho's forty-three nonmetropolitan counties, this paper tests the hypothesis that unemployment is more stable in a more diverse economy. While results support the hypothesis, other aspects of a county's economic structure are just as influential. Indiscriminate diversification will not necessarily bring economic stability.

Autores: Tew,   Bernard V.; Musser,   Wesley N.; Smith,   G. Scott.
Specification of the variance-covariance matrix holds continuing interest for agricultural economists considering risk programming applications.  This research examines alternative expected value-variance (E-V) frontiers constructed using contemporaneous and non-contemporaneous data and two statistical assumptions concerning crop prices and yields.  Empirical examples from two locations for different crops illustrate the various assumptions.  Considerable differences in the E-V efficient frontiers occur in both empirical settings.

THE INVESTMENT POTENTIAL OF WARM-SEASON GRASSES FOR HILL-LAND BEEF PRODUCERS
Provedor de dados: 31
Autores: D'Souza,   Gerard E.; Romero,   Rafael F.; Smith,   Dennis K.
The investment potential of warm-season grasses is compared with that of cool-season grasses, with special emphasis on hill-land beef production.  In addition to evaluating relative costs and returns for various grazing systems, a sensitivity analysis is conducted.  The results are then illustrated for a representative hill-land farm in West Virginia, and both an optimal and a set of quasi-optimal solutions are generated within the linear programming framework.  In general, warm-season grasses are found to be a superior investment alternative for hill-land beef producers.

DYNAMICALLY OPTIMAL AND APPROXIMATELY OPTIMAL BEEF CATTLE DIETS FORMULATED BY NONLINEAR PROGRAMMING
Provedor de dados: 31
Autores: Hertzler,   Greg.
Cattle purchasing, feeding, and selling decisions are described by a free-time optimal control model. The nutrient constraints of the National Research Council and a recently published dry matter intake constraint augment the model and make it nonlinear in the feed ingredients, the daily gain, and the weight of the cattle. Optimal feeding programs are calculated by nonlinear programming under two scenarios: first, when the feedlot has excess capacity and, second, when animals must be sold to make room in the feedlot before more can be purchased. An approximately optimal feeding program is calculated by nonlinear programming and is all but identical to the dynamically optimal programs.

Co-operation in research is a complex question which would seem to depend to a large extent on a number of necessary and sufficient conditions for success. In this note an attempt is made to define some of these conditions and then reflect on a few possibilities for co-operation between institutions, in particular between government departments and universities. First, however, it is necessary to provide a brief discussion of research objectives.

RISK EFFICIENT PERENNIAL CROP SELECTION: A MOTAD APPROACH TO CITRUS PRODUCTION
Provedor de dados: 31
Autores: Teague,   Paul W.; Lee,   John G.
Numerous studies have analyzed annual crop mix decisions in light of producer risk preferences.  Few studies have focused on perennial crop mix decisions. This study attempts to identify not only the optimal mix of grapefruit and oranges for various risk-aversion levels, but also optimal planting densities within each species.  Experimental plot data from a grapefruit and orange spacing trial over the 1970-82 period were used in MOTAD formulation to address optimal perennial crop mix and planting density decisions under different capital constraints.  An examination of results suggests crop mix and planting density diversification within and across species of citrus as a means of reducing income variability.

Credit for Alleviation of Rural Poverty: The Grameen Bank in Bangladesh
Provedor de dados: 31
Autores: Hossain,   Mahabub.
There is a growing recognition that institutional credit plays an important role in the modernization of agriculture through technological change. It is clear that as those processes of modernization occur, incomes rise and expenditures on locally produced goods and services expand in such a manner as to increase the demand for labor and labor-intensive entrepreneurial activities. The question then arises as to what extent institutional credit can be offered to very poor people to facilitate their taking direct advantage of the developing entrepreneurial activities. Perhaps the most widely admired effort to answer this question is that of the Grameen Bank in Bangladesh. One of the commendable features of the Grameen Bank is its desire to have its...

Autores: Sporleder,   Thomas L.
Marketing cooperatives operating pools that consistently obtain member returns in excess of cash market prices must accommodate new members. In some cooperatives, the membership policy is based only on the capital plan. This article presents alternative membership policies for the acquisition and transfer of rights to original members. Specific policy alternatives for each component are defined and examined. The analysis suggests that strategic planning in some cooperatives should involve explicit consideration of alternatives for membership policy.

MEASURING THE PRIMARY IMPACTS OF SEVERANCE TAXATION: A SPATIAL EQUILIBRIUM APPROACH
Provedor de dados: 31
Autores: Findeis,   Jill L.; Shortle,   James S.; Kibler,   Virginia.
A spatial equilibrium model is used to quantify the effects of a severance tax on the Pennsylvania coal market.  Two regions are identified: the Pennsylvania Market Area and an import/export region.  The impacts on prices and quantities of coal supplied and demanded are found to be small.  Little of the tax is exported from Pennsylvania, with a high proportion of the tax being passed back to Pennsylvania coal producers.  Although the tax revenue exceeds the welfare losses in Pennsylvania, this result is very sensitive to the magnitude of the Pennsylvania own-price demand elasticity.

INCORPORATING SAFETY-FIRST CONSTRAINTS IN LINEAR PROGRAMMING PRODUCTION MODELS
Provedor de dados: 31
Autores: Atwood,   Joseph A.; Watts,   Myles J.; Helmers,   Glenn A.; Held,   Larry J.
A recent survey indicated that many procedures view risk in a safety-first context. Traditional methods used to impose safety-first constraints in optimization models have often been difficult to implement. This is particularly true when endogenous decisions affect the distribution of the chance-constrained random variable.  This paper presents a method whereby probabilistic constraints can be easily imposed upon finitely discrete random variables. The procedure uses a linear version of the lower partial moment stochastic inequality. The resulting solutions are somewhat conservative but are less so than the results using the previously published mean income-absolute deviation stochastic inequality.

PROCESSOR DEMAND AND PRICE-MARKUP FUNCTIONS FOR CATFISH: A DISAGGREGATED ANALYSIS WITH IMPLICATIONS FOR THE OFF-FLAVOR PROBLEM
Provedor de dados: 31
Autores: Kinnucan,   Henry W.; Sindelar,   Scott; Wineholt,   David; Hatch,   L. Upton.
Off-flavor in catfish restricts farm marketings 10 to 45% depending on the season.  The economic impact on society of this imposed supply restriction depends, in part, on the elasticity of demand for catfish.  Econometric estimates based on disaggregated processing plant data indicate an elastic demand at the processor level but an inelastic demand at the farm level.  Short-run social welfare gains from the elimination of off-flavor are estimated to equal 12.0% of farm revenues ($10.0 million in 1983).  The inelastic demand for catfish at the farm level, however, means that most of the societal gains will accrue to individuals beyond the farm gate.  Thus, an economic justification exists for public sector funding of off-flavor research.

Provedor de dados: 31
Autores: Featherstone,   Allen M.; Schroeder,   Ted C.; Burton,   Robert O., Jr.
Suggested methods to reduce farm financial stress have included interest rate buy-downs and debt forgiveness.  This study develops a method to estimate the proportion of individual farm financial stress attributable to an income problem, a leverage problem, and an interest rate problem.  Of the Kansas Farm Management Association farms with a financial problem, 30 percent of the total financial problem is caused by an interest rate problem, 28 percent by a leverage problem, and 42 percent by an income problem.  A reduction of leverage or interest rate to the level attained by the average nonstressed farms would make 31 percent and 32 percent of the stressed farms profitable, respectively.  Therefore, in the short run, an interest rate buy-down or a debt...

TRANSFER AND ADOPTION OF THE EGYPTIAN IMPROVED "SAGIYA" IN THE NORTHERN AND KHARTOUM PROVINCES OF SUDAN
Provedor de dados: 31
Autores: Elfeil,   Mohamed Ahmed Abdel Rahman.
Lifting of water for irrigation in the Northern and Khartoum provinces of Sudan depends mainly on fuel and electrical pumps, while in Egypt more than 70% of irrigation is done by an animal drawn implement call the "Sagiya".  The shortage of fuel and electricity which started in the early seventies has resulted in a sharp reduction of agricultural output in Sudan both vertically and horizontally.  This paper demonstrates the possibility that the transfer of the Egyptian "Sagina" to Sudan may help increase the agricultural output and/or decrease the cost of production per unit of output.

TRAVEL COST METHODS FOR ESTIMATING THE RECREATIONAL USE BENEFITS OF ARTIFICIAL MARINE HABITAT
Provedor de dados: 31
Autores: Milon,   J. Walter.
The growing popularity of marine recreational fishing has created considerable interest in artificial marine habitat development to maintain and enhance coastal fishery stocks.  This paper provides a comparative evaluation of travel cost methods to estimate recreational use benefits for new habitat site planning.  Theoretical concerns about price and quality effects of substitute sites, corner solutions in site choice, and econometric estimation are considered.  Results from a case study indicate that benefit estimates are influenced by the way these concerns are addressed, but relatively simple single site models can provide defensible estimates.  Practical limitations on data collection and model estimation are also considered.

Recent changes in the feeder cattle futures contract specifications are expected to reduce hedging risk and may result in changes in optimal hedging levels. This study provides an estimate of feeder cattle hedge ratios associated with the new cash-settled feeder cattle futures contract and compares the levels of hedging risk present under the cash settled contract with the physical delivery contract. Hedging risks are compared for several weights of feeder steers and heifers and are analyzed across four market locations. Results indicate that hedging risk is generally, though not always, lower with cash settlement than under the physical delivery contract specifications.

Autores: Knopke,   Philip.
The effects of different levels of protection on productivity measures are frequently ignored in economic analysis. In this paper. a procedure is developed to net out the effects of non-marginal cost pricing on the traditional Tornqvist productivity measure. Total factor productivity in the dairy industry is estimated to have grown at a 1.5 per cent annual rate over the period 1967-68 to 1982-83. A state and regional analysis of the dairy industry showed that the Victorian industry had outperformed the New South Wales industry, a factor that was attributed to major policy differences between the two states.

Autores: Kaiser,   Harry M.; Streeter,   Deborah H.; Liu,   Donald J.
This article presents a comparative dynamic analysis of the market impact of alternative U.S. policies designed to reduce excess capacity in milk production. Two policy options are examined based on an  econometric model of the dairy industry and a dynamic simulation of the system. The stock effect policy relies on voluntary reductions in cow numbers to reduce milk supplies, while the price effect policy makes use of reductions in the support price levels to achieve the same goal. The simulation results are used to evaluate equilibrium prices and quantities for the farm and retail markets, government costs, and consumer and producer surpluses from 1986 to 1995 for each policy alternative. The analysis shows that farmers are better off under a voluntary...

SUPPLIER SUBSTITUTABILITY BY IMPORTERS: IMPLICATIONS FOR ASSESSING THE 1980 U.S. GRAIN EMBARGO
Provedor de dados: 31
Autores: Abbott,   Philip C.; Paarlberg,   Philip L.; Patterson,   Paul M.
The 1980 U.S. suspension of grain sales to the Soviet Union illustrates the importance of the choice of conceptual framework for empirical analysis of international trade problems.  A spatial equilibrium model of wheat and coarse grains trade assumes perfect substitution among exporting nations' commodities by importers and, thus, precludes the embargo from having a large impact.  The imperfect substitutability assumption of an Armington model results in larger consequences from the embargo.  For small shocks, the Armington model better captures the rigidities characteristic of international grain markets.  The spatial model provides insights on adjustments to large shocks, but rigidities persist in actual markets.

THE EFFECT OF SPATIAL VARIABILITY OF IRRIGATION APPLICATIONS ON RISK-EFFICIENT IRRIGATION STRATEGIES
Provedor de dados: 31
Autores: Bernardo,   Daniel J.
The effect of irrigation system uniformity on the selection of risk-efficient irrigation strategies is evaluated using crop simulation and stochastic dominance procedures.  Alternative strategies are evaluated under assumptions of both uniform and non-uniform application.  Results indicate that the variability of net returns resulting from the employment of a specified schedule increases when irrigation uniformity is explicitly represented.  Solutions derived using economic efficiency and stochastic dominance criteria indicate that the uniformity with which irrigations are applied contributes to the application of water-intensive irrigation schedules.

THE EFFECTS OF ALTERNATIVE SEASONAL PRICE DIFFERENTIALS ON MILK PRODUCTION IN NEW YORK
Provedor de dados: 31
Autores: Kaiser,   Harry M.; Oltenacu,   Pascal A.; Smith,   Terry R.
Uneven monthly milk production (seasonality) is a major problem in the New York dairy industry.  This article estimates expected monthly milk production response to a set of hypothetical seasonal price differentials designed to reduce the degree of seasonality.  The analysis is based on a random mail survey and farm record data.  The results indicate that a seasonal price differential of $1.12 per cwt. (over three times the current differential) would be necessary to completely balance spring and fall production in New York, based on the perceptions of farmers surveyed.  Also, producers with better managerial skills are shown to be able to reduce their seasonality at a significantly lower price differential than less skilled farm managers.

Empirical analysis examines the presence of basis risk, speculative component, and expected maturity basis component in basis relationships for nonstorable commodities. The results indicate that all three above components exist in both cattle and hog markets. The basis risk and speculative components vary across contracts. Hog markets showed seasonality, which helps explain the hog basis more accurately. Flexibility in making the marketing decision strengthens the explanation of intertemporal price relationships for both cattle and hogs beyond that previously attributed to only feed prices.

POTENTIAL WATER USE CONFLICTS GENERATED BY IRRIGATED AGRICULTURE IN RHODE ISLAND
Provedor de dados: 31
Autores: Opaluch,   James J.; Porter,   Edwin; Weaver,   Thomas F.; Gold,   Arthur.
This study constructs a simulation model to evaluate the potential for conflict among residential and agricultural users of water in southern Rhode Island.  The model estimates the profitability of irrigation and turf farms and projects the total use and the economic value of irrigation water.  The results indicate that the economic value of irrigation water compares favorably with current residential water prices in the area.  In addition, substantial demand for irrigation water is projected.  Given current rates of growth in turf acreage and residential water use, there appears to be a significant potential for conflict, particularly given the absence of well developed institutions for allocating water among users.

A WELFARE ANALYSIS OF PORT USER FEES: THE CASE OF GRAIN AND SOYEAN EXPORTS
Provedor de dados: 31
Autores: Peterson,   E. Wesley F.; Viscencio-Brambila,   Hector; Fuller,   Stephen W.
User fees have become a popular means of financing public services, including certain transportation facilities.  The Water Resources Development Act of 1986 includes provisions for user fees to finance part of the costs of operations, maintenance, and new construction of the U.S. port system.  The purpose of this paper is to evaluate the welfare implications of this legislation.  An analytical model is developed and used to estimate the impact of port user fees on grain and oilseed producers, consumers, and the government.  The results of the analysis indicate that the user fee has a relatively small effect on producer welfare and that the efficiency gains resulting from the replacement of the government subsidy for port operations, maintenance, and new...

The Effect of Sugar Price Policy on U.S. Imports of Processed Sugar-containing foods
Provedor de dados: 31
Autores: Jabara,   Cathy L.
This paper examines the effects of sugar protection, as well as the effects of these other factors, on U.S. demand for imports of sugar-containing products. The paper also addresses two main issues: (1) whether substitution of alternative sweeteners has allowed U.S. food manufactures to reduce the competitive advantage provided to foreign manufactures by U.S. sugar policies, and (2) which countries -- developed or developing -- have been able to increase their exports of sugar-containing products to the United States. Import demand functions for four categories of sugar-containing processed foods -- canned fruits, confectionary, sweetened cocoa and chocolate, and bakery products are examined.

Voos migratórios de Pieridae (Lepidoptera) no Distrito Federal, Brasil
Provedor de dados: 104
Autores: Negret,Álvaro.
Durante o período de 1976-1983, fluxos migratórios de duas espécies de Pieridae foram observados em Brasília, D.F. Esses vôos apresentaram periodicidade anual e direção constante. Na primavera, grandes concentrações de Phoebis (Aphrissa) statira voavam para sudeste, contra o vento. Durante o verão, Anteos clorinde foi observada voando contra o vento em direção oposta (SW). Essas migrações são provavelmente relacionadas a gradientes longitudinais da fenologia das plantas hospedeiras.

In this paper a new, small species of Telmatobius from the Department of Ancash, Peru, is described. Telmatobius carrillae sp. n. is compared to T. brevipes Vellard and T. marmoratus (Dumeril &amp;amp; Bibron), which are distinctly larger. Though morphologically similar to Batrachophrynus brachidactylus Peters, its chromosomic features indicate that it belongs in Telmatobius, T. carrillae could represent a connecting link between Batrachophrynus and Telmatobius.

Protozoosis caused by Vairimorpha necatrix (Microsporia, Nosematidae) in larvae of Spodoptera frugiperda (Lepidoptera, Noctuidae)
Provedor de dados: 104
Autores: Patel,Prafulbala N.; Habib,Mohamed E. M.
Vairimorpha necatrix was detected among laboratory cultured and field collected Spodoptera frugiperda larvae. Weak infections were not always fatal. In the case of fatal infections among diseased larvae, white patches were formed by agglomerations of adipose tissue beneath the transparent integument. The mid-gut of S. frugiperda larvae presented the first site of histological alterations caused by V. necatrix. The migration of the pathogen, probably occured in the form of agglomerations, from the epithelial cells to the body cavity. Adipose tissue appears to be the principal site for the pathogen development. The nerve ganglia, muscle fibres and epidermis also presented histological alterations due to the pathogen propagation.

The intermaxillary gland of Bufo paracnemis Lutz, 1925 is located at the pre-nasal area being divided anteriorly by the ascendent processes of the intermaxillary bone. The secretory tubules converge to form very ramified ducts which drain into a common opening in a fosseta underlying the vomer bone. The cells of the intermaxillary gland were be classified in four distinct types: Light-granule secretory; Dark-granule secretory; ciliated and basal cells. The light-granule secretory cells, are the main type of the secretory tubules, which are also found, in smaller numbers, in the excretory ducts. The dark-granule secretory cells appear in a low number, both in the secretory tubules and in the excretory ducts. Degranulated cells are frequently found in the...

Em uma floresta remanescente do "mato grosso goiano" (Goiânia, GO, Brasil), moscas marcadas e mutantes "white" de Drosophila melanogaster foram soltos na intersecção de dois eixos ortogonais. Foram colocadas armadilhas a intervalos de 20 m nesses eixos. Coletas periódicas, a cada meia hora, das 08:30 às 17:00 hs foram realizadas, para estudar a dispersão das moscas no meio natural e para inferir a significância do componente genético nessa dispersão. Os dados obtidos sugerem as seguintes conclusões: foi detectada dispersão ativa; essa dispersão ativa depende do genótipo (foi maior no tipo selvagem que no mutante "white"); os padrões de dispersão mudaram de acordo com o tempo; uma mobilidade presumível de 120 m/h foi detectada; uma estimativa aproximada da...

Aspectos da ecologia e da reprodução de Leptinaria unilamellata (Orbigny, 1835) (Gastropoda, Subulinidae)
Provedor de dados: 104
Autores: Dutra,Ana Virginia Calógeras.
Leptinaria unilamellata is a species of veterinary importance, being cited here in Pernambuco for the first time. Accounts of both environment and reproduction are made. Ecological observations in a population of Dois Irmãos, Recife, Pernambuco, show predominance in relation to the sympatric snail: Bulimulus tenuissimus, Subulina octona and Sarasinula sp., and showed exceptional ability to adapt to environmental conditions. From August 1982 to November 1983 a total of 1.169 specimens were collected and classified into 8 class sizes. The average occurences in each month indicate that the population is in a state of reproductive equilibrium. Sexual maturity begins at a body length of 6.1 - 7.0 mm, when the specimens (still at half their final lenght) already...

Current status of the minke whales and conflicts of interest
Provedor de dados: 104
Autores: Singarajah,K. V.
Minke whales - the rorqual group of the family Balaenopteridae - are widely distributed and constitute an important major harvestable living resource of the sea. Recently, the Antarctic minke whale population has been estimated to be between 150,000 and 300,000. Populations being dynamic entities, the size of the minke whale population has been changing. Currently , the minke whale population in the Antarctic has been claimed to have increased considerably. However, the minke whale stock arriving off Brazil could be regarded as only a small discrete unit of breeding stock and an integral part of the Brazilian natural resource. Data analysis based on the past 21 years shows that this stock is relatively in a steady state, but with only a few annual...

Phylogenetic systematics of the Eucarida (Crustacea malacostraca)
Provedor de dados: 104
Autores: Christoffersen,Martin L.
Ninety-four morphological characters belonging to particular ontogenetic sequences within the Eucarida were used to produce a hierarchy of 128 evolutionary novelties (73 synapomorphies and 55 homoplasies) and to delimit 15 monophyletic taxa. The following combined Recent-fossil sequenced phylogenetic classification is proposed: Superorder Eucarida; Order Euphausiacea; Family Bentheuphausiidae; Family Euphausiidae; Order Amphionidacea; Order Decapoda; Suborder Penaeidea; Suborder Pleocyemata; Infraorder Stenopodidea; Infraorder Reptantia; Infraorder Procarididea, Infraorder Caridea. The position of the Amphionidacea as the sister-group of the Decapoda is corroborated, while the Reptantia are proposed to be the sister-group of the Procarididea + Caridea for...

Three ariid fish, Netuma barba, Netuma planifrons and Genidens genidens, use the estuary of the Patos Lagoon (32ºS), Rio Grande do Sul, Brazil, as a nursery and feeding ground in various stages of their life history. A comparative study was made of the temporal and spatial distribution and relative abundance. Seasonal movements were interpreted on the basis of distribution and abundance of the young of these coexisting sea catfishe. Monthly otter trawl samples were made between November, 1979 and April, 1983. Temperature, salinities and dissolved oxygen contents were taken at each of the 674 sample stations. All three species were caught in ample temperature (12,1 to 26,3ºC), salinity (0,3 to 35,5‰) and dissolved oxygen (4,7 to 11,5 mg/l) ranges. However,...

Among the criteria that have been suggested for classifying South American curares: type of container, geographical origin, botanical sourcesof the active, constituent!, and chemical composition. A combination of botanical and geographical criteria leads to much the same regional ;groupings a combination of criteria involving the type of container and the chemical composition.

Foram observados aspectos estruturais que corroboram a hipótese da produção exógena das proteínas do vitelo. Os grânulos de vitelo originaram-se principalmente por condensação das vesículas pinocíticas formadas na superfície do ovócito.

Primate populations in continuous forest and forest fragments in Central Amazonia
Provedor de dados: 36
Autores: Rylands,Anthony B.; Keuroghlian,Alexine.
Population densities of six primate species (Saguinus midas, Pithecia pithecia, Cebus apella, Chiropotes satanas, Alouatta seniculus and Ateles paniscus) were estimated in continuous forest and in isolated reserves (one of 100 ha and four of 10 ha). Saguinusdensities in the continuous forest were found to be low, probably due to the lack of edge habitat and second growth favoured by them; Pithecia, Cebus and Ateles populations are also low, possibly because of more widely distributed and/or less abundant food sources than is true for other Amazonian regions, although hunting in the past, particularly of Ateles may also be a contributing factor; and Chiropotes and Alouatta densities were found to be similar to those observed in other areas of Amazonas...

Vinte espécies de madeiras, originárias do muicípio de Presidente Figueiredo - AM -UHE de Balbina, foram submetidas a ensaio de extração de pregos. Os resultados permitem avaliar a influência da densidade na resistência de arrancamento do prego e a relação da resistência entre as faces pregadas. Não se conseguindo cravar pregos em algumas das espécies ensaiadas, procurou-se determinar os fatores inerentes a madeira que dificultam a aceitação ou não do prego, como também, o diâmetro do pré-furo necessário para introdução do prego em uma amostra, tal que, a resistência a extração fosse semelhante àquela das madeiras em que foram cravados pregos sem auxilio de pré-furo.

A madeira pela sua abundância e facilidade no manuseio acompanha a evolução do modo de vida do homem. Somente quando o concreto armado passou a ser utilizado é que o uso da madeira diminuiu. Os estudos científicos sobre as propriedades físicas e mecânicas da madeira permitiram o seu emprego em igualdade de condições com outros materiais no mercado. As madeiras amazônicas a despeito da imensa floresta são utilizadas de forma pouco adequadas. Este trabalho apresenta o método estabelecido pela Norma Brasileira, com o objetivo de auxiliar o técnico, através do uso de tabelas no dimensionamento de peças sólidas de madeira submetidas à compressão paralela.

Provedor de dados: 36
Autores: Medeiros,Yara S.; Morato,Gina S.; Morato,Edelton F.; Valle,Rosa M. R.; Lima,Thereza C. M.; Rae,Giles A.; Calixto,João B.
Estudos de nosso laboratório surgerem que o ácido tânico (AT) exerce diversos efeitos "in vitro" ou "in vivo", podendo ser responsável por várias ações inespecíficas freqüentemente observadas com extratos brutos de plantas medicinais. O presente trabalho amplia estes estudos em outos modelos biológicos. A administração crônica ou aguda, por vida oral (v.o.), de AT em ratos não produziu alterações gástricas ou no processo inflamatório. Em ratos não-diabéticos observou-se modificações variáveis na glicemia de acordo com a metodologia empregada. O AT, cronicamente (v.o.), não interferiu na reprodução de fêmeas, embora constatou-se redução do número de filhotes de machos tratados. O AT (3mg/kg, v.o.) provocou aumento da diurese, porém doses mais elevadas não...

A proposed Pleistocene/Holocene lake in the Amazon basin and its significance to Amazonian geology and biogeography
Provedor de dados: 36
Autores: Frailey,Carl D.; Lavina,Ernesto Luiz; Rancy,Alceu; Souza Filho,Jonas Pereira de.
Recent studies have described widespread statigraphic units of Late Pleistocene and Holocene age in the western part of the Amazon Basin. The recognition of deltaic sedimentation in the uppermost these units near Rio Branco, Brazil, at a modern elevation of approximately 500 feett leads to the conclusion that this area was situated on the edge of a large Amazonian lake that existed in the recent past when Andean tectonism caused active downwarping of the western edge of the Amazon Basin. The ramifications of this "Lago Anazonas" hypothesis extend into every area of modern Amazonian geology and biology.

Lignóides de plantas amazônicas: investigações biológicas e químicas
Provedor de dados: 36
Autores: Gottlieb,Otto R.
Lignóides, arilpropanóides aligoméricos, possuem atividade aleloquímica nas plantas nas quais ocorrem a ação farmacológica no homem, fato que já levou a aplicações terapêuticas importantes. Os grupos mais numerosos são constituídos pelas lignanas, derivadas pela condensação oxidativa de álcoois cinamílicos entre sí ou com ácidos cinâmicos, e pelas neolignanas, derivadas pela condensação oxidativa de alilfenóis e de propenilfenóis entre sí ou cruzada. A química das lignanas é conhecida desde longa data. A química das neolignanas começou a ficar conhecida em época recente, principalmente atráves de nossos trabalhos próprios com plantas da Amazônia.

O "araça-boi" (Eugenia stipitata) é uma fruteira arbustiva nativa da Amazônia que está sendo introduzida ma agricultura moderna. Estudou-se sua fenologia na Amazônia Central em latossolo amarelo, álico, textura média, durante os primeiros 15 meses de produção. Quando juvenlí, floresce continuamente durante o ano, com quatro períodos de alta produção. Como muitas fruteiras, produz mais flores que frutos (somente 15% das flores produzem frutos que chegam à maturação). A taxa de autopolinização natural é reduzida, sugerindo que a espécie é alógama. Os polinizadores principais são as abelhas. O tempo entre floração e maturação dos frutos e de aproximadamente 34 dias.

Autores: Brocksom,Timothy J.; Canevarolo,Elisabete T.
A síntese de lactonas sesquiterpênicas do tipo guaiano é de interesse devido as atividades biológicas associadas às estruturas complexas deste grupo de produtos naturais. Planejou-se a sua síntese a partir de monoterpenos abundantes isolados de óleos essenciais brasileiros. Assim p-ment-l-eno foi transformado em 2-bromo-6-isopropil-3-metil-ciclohept-2-enona por adição de dibromocarbeno, expansão de anel com rearranjo usado AgNO3, e finalmente oxidação com clorocromato de piridinio. Redução quimioseletiva do bromo com zinco em ácido acético e alquilação termodinâmica em α,β-insaturada. Tratamento com ácido sulfúrico concentrado efetuou hidrólise e desidratação a um furano anelado a um ciclohepteno de estrutura de um oxa-guaiano.

One half of this area was in isolated forest fragments (surrounded by pastures or second growth) of two sizes: 1 and 10 ha. The other half was in non-isolated fragments (connected to a large parch of forest) of the same sizes. Only two species occured in this forest: Atta sexdens sexdens L. and A. cepfhalotes L. The first was the most abundant species with a mean density of 0.35 colonies per ha. The mean density of A. cephalotes colonies was 0.03 per ha. The density of colonies was not significantly different between the isolated fragments and the continuous forest. Furthermore, the species...

Autores: Takahashi,Reinaldo N.; Calixto,João Β.; Costa,Inés M.; Lima,Thereza C. M.; Morato,Gina S.; Nicolau,Mauro; Rae,Giles A.; Valle,Rosa M. R.; Yunes,Rosendo A.
Foram efetuados estudos químicos e farmacológicos dos extratos brutos hidroalcóolicos obtidos das folhas ou das raízes de E. argentinum ou de frações semi-purificadas desta planta. Os testes químicos revelaram a existência de alcalóides, fitoesteróides, leucoantocianidinas, glicosídeos flavonóides, cumarinas e taninos. A análise farmacológica in vivo demonstrou que o extrato das folhas é menos tóxico que o da raiz. Tanto o extrato bruto como as frações semi-purificadas obtidas das folhas reduziram a locomoção e pressão arterial de rato e potenciaram o sono barbiturico em camundongos. O extrato bruto, principalmente o da raiz, reduziu o edema induzido por carragenina na pata de rato. Testes in vitro demonstraram que o extrato bruto ou as frações...

Why further investigation of brazilian Strychnos?
Provedor de dados: 36
Autores: Angenot,L.
During the past fifteen years, African Strychnos species have been pharmacologically and chemically screened by some European Universities, sometimes with the collaboration of some African Institutes. Strychnos usambarensis will be discussed here because of our interest in it, after the discovery of its use in the preparation arrow poison with curarizing activity.The European studies have show thah the African species of Strychnoschemically are very similar to certain South-American species. Indeed, the occurrence in the African species of curarizing quaternary bases, and in the American species of tetanizing tertiary bases, such as akagerine, emphasizes the unity of genus Strychnos in terms of it alkaloids. Many biological activities (antmicrobial,...

O "chá de bugre", Casearia sylvestris Sawartz tem sido popularmente usado com várias finalidades. Mais recentemente lhe tem sido atribuído características abortivas. Esta possibilidade levou-nos a avaliar a toxicidade dos extratos brutos de suas folhas e os efeitos no útero sobre a motilidade espontânea e as contrações induzidas pela ocitocina. A dose letal média do extrato aquoso a quente é de 1,792g de resíduo por quilo de peso, para camundongos albinos. Com a solução aquosa do extrato etanólico observamos, "in vitro", na motilidade espontânea uterina de ratos aumento da freqüência de contração e do tonus basal e diminuição da amplitude de contração; na curva dose-resposta à ocitocina, diminuição da resposta máxima e aumento da dose efetiva média.

O Cannarus fulvus Planch é utilizado em Goiás por ser "bom para o coração". Este trabalho estudou, a atividade farmacológica do extrato bruto etanólico (EE) do pó da casca do caule e da fração hidrossolúvel (FH) obtida após partição benzina/água. O EE e a FH produziram em ratos e camundongos diminuição da motilidade, sonolência sem hipnose, dificuldade respiratória, analgésia e arrastamento do trem posterior; estes proporcionais às doses. As DL50 em camundongos foram 210+/-22 e 310+/-52mg/kg, i.p. para o EE e FH respectivamente. A FH prolongou o sono barbitúrico, o tempo de reação ao calor na placa, quente e antagonizou (80%) as ações convulsivantes do pentilenotetrazol, mas não as da estricnina.

Autores: Ribeiro,Maria Nilce de Sousa; Varejão,Maria de Jesus Coutinho; Zoghbi,Maria das Graças Bichara; Ribeiro,Jorge Salomão Boabaid.
Estudos de degradação de polifenóis em folhas e galhos de Inga sp., Mabea caudata Pax ex Hoffn., Mezilaurus itauba (Meissn.) Taub. ex Mez., Vatairea sericea Ducke e Protium sp. foram realizados no período de 155 dias em dois lagos experimentais situados próximos a Usina Hidrelétrica de Balbina, no Estado do Amazonas. Um dos lagos ficou com vegetação intacta e o outro foi desmatado. As determinações dos compostos fenólicos ba searam-se no método de Follin-Denis e o trabalho teve por objetivo o estudo de degradação da vegetação superior no meio aquático. Os resultados mostram que, no lago 1, Inga sp. e Mezilaurus itauba apresentaram maior taxa de decomposição, enquanto que, no lago 2, a degradação foi maior para as espécies Mabea caudata e Mezilaurus itauba.

Controle de qualidade de madeiras da região amazônica
Provedor de dados: 39
Autores: Chimelo,João Peres.
O grande número de espécies encontrado nas florestas tropicais úmidas tem sido mencionado freqüentemente como um dos principais obstáculos a uma utilização mais intensiva da madeira em países em desenvolvimento. Este trabalho descreve dois exemplos de como o conhecimento da anatomia e das propriedades físicas e mecânicas das espécies abundantes, aliado a um esquema adequado de controle de qualidade, pode viabilizar uma maior utilização de madeiras da amazónia brasileira. O primeiro exemplo se refere à produção de dormentes para a Estrada de Ferro Carajás (E.F.C.) com 890 km de extensão, onde foram empregados cerca de 2.100.000 dormentes; o segundo trata do uso de madeira serrada para habitação de baixo custo, no Estado de São Paulo, cuja construção é...

A note on the seasonally shifting zone of high primary production in the Bay of Marajó, Pará, Brazil, 1983-1984
Provedor de dados: 39
Autores: Schwassmann,H.O; Barthem,R.B; Carvalho,M.L.
To understand the hydrological and limnological conditions during the annual regime of high and low river flow, as well as the action of the tides, a series of 18 collecting trips were conducted in monthly and bimonthly intervals across the Bay of Marajó during the years 1983-1985. The Tocantins River provides more than 80% of the inflow into this bay and shows a much greater difference in water volume flow between high and low water season than the Amazon. The annual displacement of brackish water influence is thus more extensive Marajó Bay than in the Amazon estuary. During the dry season of low river discharge (September-December), traces of seawater are found to penetrate up to 90 km upriver in the Guamá River. The high degree of turbidity of inner...

Uso de Sphagnum recurvum P. Beauv. como biofiltro no monitoramento de poluição aérea industrial de metais pesados
Provedor de dados: 39
Autores: Gutberlet,Jutta.
O uso de bioindicadores e biofiltros, principalmente plantas inferiores, representa uma alternativa eficiente no monitoramento da qualidade ambiental. A vantagem do emprego de vegetais na avaliação da contaminação ambiental consiste no reduzido custo de instalação e no fato de poder retratar uma situação global, integrando a soma dos diferentes efeitos dos agentes contaminantes. Segundo o método "moss-bag", adaptado aos fatores regionais específicos, foram empregados saquinhos de nylon contendo o musgo Sphagnum Recurvum P. Beauv. como biofiltro dentro do estudo realizado na Serra do Mar de Cubatão/SP/Brasil. A contaminação atmosférica de metais pesados (Al, Fe, Ni, Zn) foi monitorada mensalmente durante o ano de 1987. Primeiros dados analíticos sobre a...

Autores: Silva Júnior,Manoel Cláudio da; Silva,Alexandre Francisco da.
Este estudo foi realizado no cerrado (sensu stricto) da Estação Florestal de Experimentação de Paraopeba-MG, pertencente ao Instituto Brasileiro de Desenvolvimento Florestal (IBDF). Para o levantamento florístico utilizou-se o método de quadrantes, incluindo-se os indivíduos com diâmetro mínimo do tronco de 5cm ao nível do solo. Foram alocados 25 pontos de amostragem em cada uma das 20 áreas selecionadas pela homogeneidade fisionômica. A distribuição dos diâmetros dos 2.000 indivíduos amostrados apresentou-se não balanceada, indicando uma grande representação (66,55%) na menor classe de diâmetro (5-10cm), podendo isto ser devido ao restabelecimento das populações na área após o desmatamento ocorrido em 1952. Esta hipótese sugere que 30 anos seria um prazo...

Ação inibidora do Cepa (Ácido 2-Cloroetilfosfônico) sobre a germinação de sementes de Euphorbia heterophylla L
Provedor de dados: 39
Autores: Suda,Cecília N. K; Giorgini,Jaibas F; Gusman,Antonio B.
Euphorbia heterophylla L. (amendoim-bravo) é uma planta invasora de culturas anuais e perenes e ocorre principalmente em plantações de soja. As sementes de E. heterophylla foram classificadas em escuras e claras com base na coloração da testa. Ambos os tipos de sementes foram colocados para germinar em presença de Cepa em concentrações de 10, 100 E 1000 ppm. Foi verificado que o Cepa, nas três concentrações ensaiadas, inibiu a germinação de sementes escuras e claras de E. heterophylla. A cor da semente não tem influência sobre a porcentagem de germinação, tanto na presença como na ausência de Cepa, após 4 dias a partir do início da embebição.

Com os dados de 21 parcelas permanentes de 1.000m² (20 x 50m) alocadas no inventário contínuo de uma faixa de cerrado com 152ha (400 x 3.800m) na Fazenda Água Limpa (FAL)-DF (15º56'14"S e 47º46'08"W), foi realizado o estudo da distribuição diamétrica dos indivíduos com mais de 5cm de diâmetro a 30cm do solo. Foram estudadas também as 17 espécies com maior índice de importância (IVI). Para a população total, 63,85% dos indivíduos concentram-se na primeira classe de diâmetro (5-9cm), fato atribuído ao pequeno porte que geralmente apresentam algumas das espécies do cerrado e/ou à incidência de incêndios em intervalos que, na maioria das vezes, não ultrapassam três anos.

Autores: Santos,Durvalina Maria Mathias dos; Marinis,Giorgio de.
O presente trabalho visa conhecer a taxa de multiplicação e o índice de mortalidade de S. punctata a diversas concentrações do butaclora, propanila e glifosato bem como comparar dois métodos diferentes de investigações (ensaio 1 e 2). Os dados indicaram que no ensaio 1 as concentrações foram pouco tóxicas provocando baixos índices de mortalidade embora tenha ocorrido inibição do crescimento nas concentrações mais fortes. O ensaio 2 mostrou que a butaclora e a propanila são mais tóxicas que o glifosato, com valores de mortalidade de 100% em apenas 48 horas. A taxa de multiplicação, neste ensaio, somente foi determinada para o glifosato, pois os demais herbicidas foram altamente tóxicos para a espécie. Verificou-se, na comparação dos dois métodos diferentes,...

Reatividade de calcários agrícolas e a relação entre os teores de cálcio e magnésio
Provedor de dados: 43
Autores: Bellingieri,P.A.; Alcarde,J.C.; Souza,E.C.A.
A reatividade da fração retida entre as peneiras nºs 50-60 (ABNT) de quatro calcários, com teores relativos de óxidos de cálcio decrescentes e de óxidos de magnésio crescentes, foi avaliada incubando-os , durante 100 dias, com três solos diferentes. O delineamento foi o de blocos casualizados com 6 tratamentos e 4 repetições. A avaliação, feita através das variações periódicas do pH e dos teores de alumínio, cálcio e magnésio trocáveis, mostrou que a relação entre os teores de cálcio e magnésio nos calcários não influi na sua reatividade, tanto quanto à correção da acidez dos solos como ao fornecimento de cálcio e de magnésio.

Atividades de transaminase glutamico-oxaloacético e transcarbamilase de ornitina em folhas de feijoeiro (Phaseolus vulgaris L.) afetadas pela deficiência de potássio
Provedor de dados: 43
Autores: Gutierrez,L.E.; Crocomo,O.J.
Folhas de feijoeiro (Phaseolus vulgaris L.) normais e deficientes em potássio dos cultivares Rosinha Precoce e Goiano Precoce foram analisadas para determinação das atividades de transaminase glutâmico-oxaloacético (E.C. 2.6.1.1) e transcarbamilase de ornitina (E.C. 2.1.3.3). Em plantas deficientes em potássio houve aumento na atividade das duas enximas estudadas e nos dois cultivares. Esses resultados explicariam o acúmulo de citrulina e arginina em plantas deficientes em potássio devido a maior atividade da transcarbamilase de ornitina, que possivelmente seria um mecanismo de reduzir a toxidez por amônia.

Autores: Bellingieri,P.A.; Alcarde,J.C.; Souza,E.C.A.de.
A solubilidade de quatro calcários agrícolas, dois sedimentares e dois metamórficos, divididos em quatro frações granulométricas, foi estudada em dois extratores químicos (soluções de ácido clorídrico e de ácido acético), em variadas condições, com o objetivo de avaliar a eficiência desses materiais através desse critério. Os resultados obtidos, comparados com os ensaios de incubação com solos, mostraram que para a pretendida avaliação, os extratores não se prestam para avaliar os calcários agrícolas, visto que não há correlação entre a solubilidade, expressa em equivalente de CaCO3, e a eficiência mostrada nos ensaios de incubação com solos.

Autores: Bellingieri,P.A.; Alcarde,J.C.; Souza,E.C.A. de.
Foram comparados os valores do PRNT de calcários agrícolas, empregando fórmulas que se baseiam em diferentes valores de eficiência relativa das frações granulométricas que compõem esses materiais. Foram utilizadas 22 amostras de calcários, sendo 12 de Rio Claro, Piracicaba e Tietê, Estado de São Paulo e as demais especialmente escolhidas visando variação nas composições granulométrica e química. Os resultados sugerem que as fórmulas de PRNT que têm sido utilizadas no Brasil , devem estar substimando a eficiência desses produtos , além de carecerem de um respaldo experimental mais convincente. A nova fórmula proposta pode ser mais confiável, apesar de estar também sujeita a várias críticas.

O Termofosfato reduziu tanto a acidez ativa quanto a acidez trocável em ambos os solos. A fosforita de Olinda e o Superfosfato simples reduziram a acidez de troca mas afetaram muito pouco o pH dos dois solos.

Melhoramento do cafeeiro: XLII. Produtividade de progênies derivadas de hibridação dos cultivares Laurina e Mundo Novo
Provedor de dados: 53
Autores: Carvalho,Alcides; Fazuoli,Luiz Carlos; Mazzafera,Paulo.
O cultivar Laurina de Coffea arabica L. caracteriza-se pelo pequeno porte, folhas de dimensões reduzidas, frutos afilados na base, sementes pequenas e afiladas, pequeno rendimento e reduzida produção. Apresenta, no entanto, bebida de boa qualidade e baixo teor de cafeína nas sementes. Suas principais características são controladas pela ação de um par de alelos recessivos lrlr, de acentuado efeito pleiotrópico. Devido ao atual interesse do comércio por produto de baixo teor de cafeína, iniciaram-se pesquisas tendo em vista principalmente aumentar a produtividade do 'Laurina'. Para esse fim, realizaram-se numerosas hibridações de cafeeiros do 'Laurina' com os do 'Mundo Novo' (Coffea arabica) e, posteriormente, retrocruzamentos com o 'Mundo Novo'....

Autores: Lorenzi,José Osmar; Valle,Teresa Losada; Monteiro,Domingos Antonio; Costa,Álvaro Santos.
Visitaram-se culturas de "fundo de quintal" em 126 municípios paulistas, cujas observações permitiram verificar a ocorrência da micoplasmose, conhecida por superbrotamento-de-santa-bárbara-do-rio-pardo, em doze daqueles municípios. Os resultados evidenciaram a existência, no Centro-Sul do Estado, de um foco que se alastra por doze municípios relativamente próximos, tendo como área de concentração o de Aguas de Santa Bárbara, onde, pela primeira vez, em 1969, constatou-se a moléstia, não observada nos outros 114 municípios. São brevemente discutidas prováveis causas da perpetuação do micoplasma causador e sugeridas algumas medidas de controle.

A carência de mudas enxertadas de nogueira-macadâmia (Macadamia integrifolia Maid. e Bet.) constitui, ainda hoje, um dos grandes entraves ao efetivo estabelecimento da cultura nas condições brasileiras. Apesar dos recentes avanços técnicos conseguidos na sua propagação, o procedimento adotado à produção de mudas ainda demanda um período de dois a três anos, para sua efetiva instalação no campo. Neste trabalho, levado a efeito na Estação Experimental do Instituto Agronômico, em Tietê, SP, demonstrou-se a exequibilidade de produção de mudas de macadâmia, em tempo bem mais abreviado, isto é, apenas doze meses. O novo processo de obtenção de mudas precoces de macadâmia, sob ripado, pela enxertia de garfos pouco lignificados e protegidos com saquinhos...

A principal restrição para o emprego de modelos agrometeorológicos de previsão de safras é a falta de informação mais completa sobre a produtividade potencial dos cultivares de soja. Assim, adaptou-se um modelo agrometeorológico de estimativa da produtividade potencial baseado em modelo proposto pela FAO, onde se incorporou um fator referente à penalização para excedentes hídricos. Estimou-se experimentalmente a produtividade potencial em função da época de semeadura para os principais cultivares recomendados para o Estado de São Paulo, a partir de séries de cultivo efetuados na Estação Experimental de Ribeirão Preto (SP), do Instituto Agronômico, durante oito anos consecutivos. Os cultivares IAC-11, IAC-12, IAC-8 e IAC-10 apresentaram as maiores...

Realizaram-se comparações entre as sementes dos cultivares Mundo Novo de Coffea arabica, cujo endosperma é verde, com as do cultivar Cera, dessa espécie, de endosperma amarelo, com o objetivo de determinar os componentes responsáveis por aquela cor. Nas análises de clorofilas, flavonóides, diterpenos totais, ácido clorogênico e íons Mg, Ca, K, Fe e B, nenhuma diferença foi verificada entre os dois cultivares, sugerindo que a coloração verde se deva à presença de outros componentes ou que o 'Cera' apresente um componente que não ocorre no 'Mundo Novo' e que inibe o desenvolvimento da cor verde no seu endosperma.

Autores: Hiroce,Rúter; Benatti Júnior,Romeu; Feitosa,Celi Teixeira.
Em solo hidromórfico do Vale do Ribeira, SP, conduziram-se dois ensaios de adubação N, P, K e calagem com junco-sete-ilhas (Cyperus malaccensis Lam.), sendo um em casa de vegetação e outro, em condição de campo. Em ambos, o nitrogênio foi o nutriente que provocou aumentos mais elevados na produção de matéria seca, sendo potássio o nutriente mais absorvido. O tratamento NPK mais calcário provocou a maior produção de matéria seca e plantas com hastes mais grossas. A extração de nutrientes, no tratamento completo, obedeceu à seguinte ordem decrescente: K, N, Ca, S, Mg, P, Mn, Fe, Zn, B e Cu.

A deficiência de boro é rara na cultura da soja no Brasil. A deficiência aqui descrita ocorreu em Guaíra, SP, numa várzea onde houve excessiva aplicação de calcário, elevando a saturação por bases a valores próximos de 90%. Nas áreas deficientes, o teor de boro no solo foi de 0,06 ppm e nas áreas aparentemente sem sintomas, 0,11 ppm. Nas folhas das plantas com sintomas, a concentração era de 10 ppm de boro e nas sem sintomas, de 19 ppm. Nas plantas deficientes, as folhas primárias eram coriáceas e espessas, e houve morte da gema apical, com brotamento de gemas laterais, nanismo, poucas flores e pequeno pegamento de vagens, com sensível redução na produtividade.

Em experimento conduzido na Estação Experimental de Mococa, num latossolo vermelho-escuro álico, A moderado, textura argilosa, com quatro níveis de calagem (1, 4, 7 e 10 t/ha de calcário dolomítico), procurou-se avaliar o efeito dessa prática sobre a concentração de zinco nas folhas de soja em três plantios sucessivos a partir de 1980. Observou-se, através dos anos, um decréscimo nos teores de Zn nas folhas. Nos três anos, a calagem deprimiu a concentração de Zn nas folhas. Mesmo nos níveis mais altos de calcário, porém, não foram atingidos teores considerados deficientes.

Foram realizados testes em meio de cultivo acidificado para avaliar a tolerância de 59 estirpes de Bradyrhizobium sp. isolados de Mimosoideae. As culturas, por via de regra, apresentaram crescimento rápido e alcalinização do meio. Das estirpes testadas, dez apresentaram crescimento em meio com valor de pH 4,6 (três, crescimento rápido; um, médio e seis, lento). Destas, oito não induziram alteração visual na cor do indicador bromotimol-azul incluído no meio. A estirpe SMS-513, uma entre essas oito, promoveu acidificação no meio com valor de pH 6,2, sendo considerada tolerante à acidez. Algumas estirpes cresceram em meio de cultura acidificado, somente com alta concentração inicial de células.

Deficiência hídrica simulada nos diferentes estádios de desenvolvimento de um cultivar precoce de soja
Provedor de dados: 53
Autores: Nogueira,Sandra dos Santos Seva; Nagai,Violeta.
Estudou-se o efeito da deficiência hídrica em diferentes estádios do cultivar precoce de soja Paraná. As plantas foram cultivadas em casa de vegetação, em solução nutritiva de Hoagland. A deficiência hídrica foi simulada pela adição de polietilenoglicol (PEG) 6% na solução nutritiva, nos seguintes estádios: vegetativo, florescimento e enchimento do grão. Os resultados mostraram que: (1) a deficiência hídrica nos três estádios diminuiu a produção e o número de vagens e de grãos em relação à testemunha; (2) no período do enchimento do grão diminuiu o peso do grão e a produção, com relação ao estádio vegetativo. Concluiu-se que a deficiência foi mais prejudicial nos estádios reprodutivos, devido à diminuição da produção de grãos.

Realizou-se um experimento de irrigação e adubação de rami em latossolo roxo, no Centro Experimental de Campinas, SP, de 1956 a 1961. Os tratamentos consistiram em parcelas com e sem irrigaçâo, recebendo ou não adubação completa anualmente. Efetuaram-se as irrigações quando consumidos de 60 a 70% da água disponível nos primeiros 50cm do perfil do solo (cerca de 0,3 MPa). A irrigação trouxe um aumento médio de 175% na produtividade dos tratamentos adubados e nâo-adubados quando comparados à testemunha. Embora menores, a adubação também trouxe incrementos adicionais de produção. Em conjunto, ambas elevaram 212% a produção total de fibras em relação à testemunha.

Situação nutricional de seringais produtivos no estado de São Paulo
Provedor de dados: 53
Autores: Bataglia,Ondino Cleante; Cardoso,Mário; Carretero,Miguel Viscaíno.
Avaliou-se o estado nutricional de quarenta seringais em produção, instalados em diversas regiões edafoclimáticas paulistas, por meio da análise química foliar e dos solos correspondentes. As amostragens de folhas foram feitas no verão e no outono e as de solo, apenas na primeira época, ambas em 1984 e 1985. De forma consistente, verificaram-se baixos níveis de P nos solos de quase todos os seringais e de K naqueles localizados no litoral. A acidez apresentou grande variabilidade, registrando-se desde baixos índices de saturação por bases em solos do litoral e na região dos latossolos vermelho-escuros de textura média até níveis bastante elevados nos latossolos roxos eutróficos e nos podzólicos. Embora não se tenham registrado deficiências de...

Capacidade de germinação e quebra de dormência em sementes de cultivares de videira
Provedor de dados: 53
Autores: Pommer,Celso Valdevino; Maeda,Jocely Andreuccetti; Ribeiro,Ivan José Antunes.
Com a finalidade de gerar plântulas para o melhoramento genético, investigou-se a germinação de sementes de uva estudando-se a estratificação a frio, a aplicação de giberelina e a interação desses fatores. A conjugação de períodos de estratificação maiores que 13 dias com doses de giberelina (GA3) mostrou-se útil na quebra da dormência e na redução do seu tempo. A dose ideal de GA3 foi encontrada ao redor de 2.000 ppm e o menor período de estratificação, de cerca de 32 dias. Sementes de 61 progenitores potenciais foram germinadas em vasos com terra, mostrando-se a maior parte deles apta a ser usada em programas de melhoramento, com germinação superior a 45%, após os tratamentos indicados.

Tolerância de trigo, triticale e centeio a diferentes níveis de ferro em solução nutritiva
Provedor de dados: 53
Autores: Camargo,Carlos Eduardo de Oliveira; Felício,João Carlos; Freitas,José Guilherme de; Ferreira Filho,Antonio Wilson Penteado.
Em um experimento estudou-se o comportamento diferencial de treze cultivares de trigo, seis de triticale e um de centeio e, em outro, o comportamento de vinte cultivares de trigo, empregando-se soluções nutritivas arejadas contendo cinco concentrações de ferro (0,56; 5,0; 10,0; 20,0 e 40,0 mg/litro) à temperatura de 25 ±1°C, e pH 4,0. A média do crescimento das raízes dos cultivares, durante doze dias, nas diferentes soluções de tratamento foi o parâmetro utilizado para a avaliação da tolerância. Os cultivares de trigo IAC-212 e IAC-215 (Experimento 1) e IAC-29, IAC-74, IAC-203, IAC-207 e IAC-211 (Experimento 2) foram tão tolerantes ou mais que o 'Siete Cerros', empregado como controle, constituindo-se em fontes genéticas de valor para o programa de...

Densidade básica do colmo e fibras celulósicas em progênies de Bambusa tuldoides Munro
Provedor de dados: 53
Autores: Azzini,Anisio; Ciaramello,Dirceu; Salgado,Antonio Luiz de Barros; Tomazello Filho,Mário.
Na espécie Bambusa tuldoides em vinte e uma progênies, determinou-se a densidade básica do colmo, o rendimento em fibras celulósicas e as dimensões destas. A densidade básica variou acentuadamente de 0,407 a 0,712g/cm³, evidenciando alterações nas características químicas e anatômicas dos colmos. As variações nos rendimentos em fibras celulósicas - 45,67 a 56,78% - não foram significativas, sugerindo que a quantidade de fibras no colmo pouco influi em sua densidade básica. Esta característica foi influenciada pelo diâmetro de lúmen das fibras, sendo o maior lúmen (4,86 microns) responsável pela menor densidade básica (0,407g/cm³). O comprimento médio das fibras celulósicas da espécie Bambusa tuldoides (1,97mm) e suas progênies (1,49 a 3,17mm) ocupou uma...

Arroz e trigo: tolerância à salinidade em solução nutritiva
Provedor de dados: 53
Autores: Freitas,José Guilherme de; Camargo,Carlos Eduardo de Oliveira.
O estresse hídrico é uma das principais causas da baixa produtividade de grãos nas culturas de arroz e trigo-de-sequeiro no Brasil. Um programa de melhoramento genético usando um método para selecionar plantas tolerantes ao estresse hídrico diminuiria bastante esses efeitos negativos: por isso, tentou-se verificar os comportamentos de cultivares de arroz (sequeiro e irrigado) e trigo sob estresse salino considerando que estes se correlacionassem. Realizaram-se dois experimentos no laboratório da Seção de Arroz e Cereais de Inverno do Instituto Agronômico de Campinas, empregando soluções nutritivas. Os cultivares estudados foram os seguintes: arroz-de-sequeiro: IAC-25, IAC-47, IAC-164, IAC-165, IAC-1246, Batatais, Pérola, Pratão Precoce e Dourado Precoce;...

Mutante somático sem sementes em videira 'Niagara Rosada'
Provedor de dados: 53
Autores: Pires,Erasmo José Paioli; Pommer,Celso Valdevino; Passos,Ilene Ribeiro da Silva; Terra,Maurilo Monteiro.
É relatada a ocorrência de mutação somática provocando apirenia no principal cultivar de uvas para mesa em São Paulo, Niagara Rosada. O mutante, surgido em Jundiaí, SP, em 1982, apresenta a mesma coloração das bagas, porém as dimensões físicas são drasticamente reduzidas, como o peso do cacho (237%) e das bagas (218%), o comprimento e a largura dos cachos (33 e 70%) e das bagas (58 e 43%). A partir desse mutante, constituiu-se novo cultivar, que recebeu a denominação de Rosinha. Discute-se seu grande potencial em vista da vantagem da apirenia, tanto para o produtor como para o consumidor, e seu uso como progenitor masculino em programas de melhoramento genético de uvas para mesa.

Autores: Siqueira,Walter José; Fonseca,Monique Ines Segeren; Sondhal,Maro R.
Calos obtidos da cultura in vitro de embrião imaturo do cruzamento interespecífico L. esculentum x L. peruvianum, praticamente perderam a capacidade morfogenética, após dois anos de subcultura. Na tentativa de recuperação do processo de organogênese desses calos, realizaram-se dois experimentos, utilizando-se os fitorreguladores ácido indolacético (IAA) e 6-benziladenina (6-BA), cujas concentrações foram combinadas em dialélicos de 5 x 5 e 3 x 3. A composição de sais minerais e vitaminas baseou-se no meio de Murashige e Skoog, adicionando-se sacarose a 3% e ágar a 0,8%, e ajustando-se o pH final dos meios de cultura para 5,5. As condições para o dialélico 5 x 5 foram fotoperíodo de 16 horas de luz a 600 lux e temperatura de 25 ± 3°C. No dialélico 3 x 3, os...

En busca del pueblo perdido: el proceso de diferenciación de la izquierda marxista ecuatoriana durante la década del sesenta, analizado a través del discurso político
Provedor de dados: 122
Autores: Bonilla, Adrián.
En los años sesenta las heterodoxias de la izquierda se multiplicaron y con ellas se introdujeron prácticas de insubordinación y ruptura inéditas en nuestra historia política. Estos temas son estudiados críticamente desde la perspectiva teórica del discurso político, en tanto práctica social por sí misma, con el fin de explicar el ambiente societal que produjo. El autor describe las dinámicas de la diferenciación izquierdista de los sesenta entendiéndola como la génesis de lo que es la izquierda contemporánea a través de tres vertientes: la comunista, la socialista y la maoista, así como los orígenes de la participación política violentista que, empezando hace treinta años, cobra fuerza en los ochenta.
