Цикл  органического углерода в океанах
Provedor de dados: 13
Autores: Вангерски, П. Дж.
Современные исследования цикла органического углерода в море привели к перестройке прежних  представлений.  Важный вклад новых  данных  и представлений связан с оценками скоростей процессов, в особенности первичной  продукции  и  регенерации питательных веществ, скоростей выделения органического вещества в растворенной форме. Вскрылась важность разномасштабных процессов перемешивания  для первичной продукции.  Важными представляются оценки скоростей седиментации разных фракций мертвого органического вещества. Роль бактерий в цикле углерода, по-видимому, значительно больше, чем  это  предполагали ранее. Больше и часть первичной продукции, направляемая в бактериальное звено.

Концептуальная эволюция модели  морского  биоценоза и обмена веществ в нем
Provedor de dados: 13
Autores: Хайлов, К. М.
Дан  обзор современной биоокеанографической литературы  в  области экологической  биохимии  и экологии. Общее направление концептуальной эволюции  модели морского биоценоза — развитие первоначальной упрощенной  схемы  пастбищной пищевой цепи  с однонаправленным потоком  вещества и энергии  в сложную  поточно- цикличную схему, в которой циклы не  менее важны,  чем  потоки  в  одном направлении, а массообмен равноважен, а в ряде случаев более важен, чем  энергообмен. Основные этапы эволюции:  а) расширение  представлений о роли  детрита и его динамике; б) исследование многочисленных утечек углерода в среду в форме минеральных и  растворенных органических метаболитов; в) исследование возвратных  процессов и циклов регенерации углерода; г) перенос интереса от...

Распределение зоопланктона над поднятиями  дна в  Южной Атлантике
Provedor de dados: 13
Autores: Ковалев, А. В.; Балдина, Э. П.; Морякова, В. К.
По  материалам 11-го рейса НИС «Профессор  Водяницкий»  исследовано распределение микро- и мезозоопланктона над четырьмя  подводными поднятиями и в прилегающих водах в тропической зоне  Южной Атлантики. Над мелководными поднятиями Дейвис и Вальдивия пространственное распределение зоопланктона, в частности  микрозоопланктона, оценивается  как статистически неслучайное.  Относительно высокие показатели численности и биомассы, как правило, совпадали с зонами подъема  вод. Глубоководные поднятия Модельная и Удачная не оказывают заметного влияния на количественные показатели и распределение зоопланктона в поверхностном слое океана.

Представлены результаты измерения концентраций хлорофилла «а» и феофитина «а» в поверхностном слое и слое фотосинтеза над банками в Южной Атлантике с помощью флюориметрического метода. Статистический анализ результатов показал случайный характер распределения концентраций хлорофилла «а» в поверхностном слое и слое  фотосинтеза.  Отсутствие  детерминированной составляющей свидетельствует, что  исследованные  банки  не  оказывали  существенного влияния на распределение концентрации пигмента. В поверхностном слое океана обнаружено до 40—50% феофитина, и это  соотношение хлорофилла и феофитина сохранялось вплоть до глубины залегания максимальной концентрации пигмента.  С глубиной процент   феофитина увеличивался и достигал 90—100% на горизонтах 150—200 м.

аланс энергии двух популяций равноногих ракообразных в  Черном  море
Provedor de dados: 13
Autores: Аболмасова, Г. И.; Печень-Финенкo, Г. А.; Романова, 3. А.
У двух  видов равноногих  ракообразных Idotea baltica  и  Sphaeroma serratum, обитающих в береговых выбросах макрофитов, установлены основные закономерности продуцирования и использования энергии популяциями этих рачков на протяжении годового цикла в прибрежной зоне Черного моря.      Скорость дыхания,  питания,  интенсивность  продуцирования популяции сфером значительно ниже, чем у идотей. Несмотря  на сравнительно низкую интенсивность всех биоэнергетических процессов  у сфером  на организменном уровне, благодаря большой биомассе  (в 6,7 раза превышающей среднегодовую биомассу идотей) они играют большую роль в переработке  органического  вещества  в  биоценозе прибрежных выбросов.

Autores: Печень-Финенко, Г. А.; Аболмасова, Г. И.; Романова, 3. А.
На основе изучения, отдельных элементов (скорости питания, энергетического обмена, генеративного, экзувиального  и соматического роста) в разных температурных условиях рассчитан  полный энергетический бюджет у двух видов равноногих ракообразных  Idotea baltica basteri Aud и Sphaeroma serratum Fabr.       Количественная оценка параметров показала, что скорость всех биоэнергетических процессов при исследованных температурах выше у  более подвижных  идотей, однако эффективность их практически  одинакова у обоих видов и не зависит от температуры.

Реализован подход к сложному слоевищу морского низшего  растения (цистозиры) как к ансамблю гомологов элементарно простой геометрической формы (осевых структур — «осей»).  По ряду морфологических и функциональных параметров рассмотрено частотное распределение осевого ансамбля цистозиры. За основание ряда принята индивидуальная  масса  как  частный  случай размерного  спектра. Показано, что и отдельное сложное растение, и морская  экосистема  могут быть содержательно описаны  как «размерные спектры»  полидисперсного  живого  вещества  в  понимании В.И. Вернадского.

Описаны  методика сбора и подготовки проб к хемилюминесцентному анализу,  метод измерения и обсчета данных. Концентрации АТФ на поверхности составили в среднем 19 нг/л. Для  горизонта 5 м — 22 нг/л. С глубиной концентрация АТФ повышалась, достигая 40—80 нг/л. Размещение зон повышенных  концентраций  АТФ в общих чертах совпало  с  зонами повышенного содержания  хлорофилла «а».  Биомасса микропланктона по данным АТФ составила для слоя 0—5 м в среднем 5,25  мг/м3 Сорг,  что  определяет исследованную акваторию  как  олиготрофную.

Изучение влияния некоторых факторов на процессы окисления нефти
Provedor de dados: 13
Autores: Лебедь, А. А.
Биомасса углеводородокисляющих микроорганизмов нарастает на  5-е сутки и при дальнейших  длительных пересевах время адаптации  ее к углеводородам нефти не изменяется. За это же время окисляется и максимальное количество  нефти. Установлено, что  при наращивании  биомассы углеводородокисляющих микроорганизмов  на чашках Петри с РПА она не теряет способности окислять углеводороды. Накопительная культура бактерий быстрее и полнее утилизирует углеводороды  по  сравнению с монокультурой, а пленочная нефть окисляется микроорганизмами лучше, чем эмульгированная. При добавлении к морской воде бытовых сточных  вод в качестве дополнительной органики имеют место процессы соокисления.

Применение  различных  видов стимуляции — химической,  электрической и  механической — для  выяснения светоизлучательной  активности копепод рода Pleuromamma показало их неравноценность. Максимальными энергетическими и временными показателями  биолюминесценции характеризуются  сигналы,  вызванные химическим  раздражением. При механической стимуляции  интенсивность и общая  энергия светоизлучения наименьшие и могут быть на порядок  ниже. При химическом  раздражении наблюдается менее синхронный выброс светового субстрата,  чем при механическом и электрическом  возбуждениях.  Длительность воздействия  стимула на  организм — наиболее существенная характеристика раздражителя, влияющая на все параметры  светового сигнала.

Об  изменении содержания  белка  в  тканях мидий при  экстремальных воздействиях (в условиях  эксперимента)

Autores: Шапиро, А. З.; Звездовская, Н. М.
В условиях экспериментальной гипоксии и интоксикации мидий  ионами меди отмечено изменение содержания общего, водорастворимого  и  структурного белков. Степень уменьшения концентрации  белка  определяется длительностью  условий гипоксии и функциональной  активностью тканей в организме.  Электрофоретический анализ солерастворимых белков показал перераспределение интенсивности фракций в белковом спектре тканей мидий при указанных воздействиях  и достоверное изменение частоты встречаемости отдельных полос в  области быстро- и медленноподвижных белковых фракций.

Планктонные исследования у Гвинейского побережья Атлантики.  I. Сопоставление методов  количественного учета фитопланктона
Provedor de dados: 13
Autores: Чмыр, В. Д.; Сеничева, М. И.
Дана  оценка первичной продукции  (113—418 мг С/(м3·сут),  концентрации хлорофилла «а» (1,3—8,5 мг/м3), численности (до 109 кл/м3 и выше) и биомассы (до 10 г/м3) фитопланктона в поверхностном слое прибрежного мелководья у г. Конакри. Биомасса зоопланктона в межостровной лагуне островов Лос составляла  1—16 г/м2 (глубина до 13 м). Контрольные измерения прямым счетом  клеток диатомовых в естественной  концентрации показали, что общепринятые методы сгущения фитопланктона путем фильтрования и осаждения привели к занижению численности в 2,95—5,41 и биомассы в 2,74—5,83 раза. Исследования проводили с декабря 1979 г. по сентябрь 1980 г. на базе Гвинейского океанографического центра.

Продукция  тропических  копепод  в разных пелагических скоплениях Индийского океана
Provedor de dados: 13
Autores: Сажина, Л. И.
В марте—июне 1980 г.  на борту  НИС «Профессор  Водяницкий»  исследовали показатели размножения и роста массовых видов копепод  из разных районов Индийского океана, отличающихся уровнем продуктивности. В локальных скоплениях планктона, образованных циклоническими круговоротами, происходит интенсивное размножение  преимущественных фитофагов, увеличивающее генеративную часть в  общем приросте.  Понижение  продуктивности  района приводит  к снижению скорости размножения у фитофагов, увеличению роли хищных видов в продукционном процессе, возрастанию  значимости соматического прироста.      Свойственный большинству фитофагов и эврифагов вымет яиц в  воду является экологическим признаком, направленным на  быстрое увеличение популяции в локальных, часто...

Изучение экологической изменчивости  черноморских видов  Cystoseira  Ag. с помощью метода главных  компонент
Provedor de dados: 13
Autores: Парчевский, В. П.; Хайлов, К. М.; Калугина-Гутник, А. А.
Проанализирована с помощью метода главных  компонент  изменчивость двенадцати морфологических признаков и глубины обитания двух видов черноморских бурых водорослей Cystoseira barbata (f. barbata  и f. hoppii) и С. crinita (f. crinita). С помощью первых четырех главных компонент у всех трех цистозир объясняется примерно 80% исходной изменчивости. Морфологическая  изменчивость цистозир отражает изменчивость площади поглощающей поверхности водорослей, характеризующей их адаптивные возможности.  По ширине экологических ниш цистозиры располагаются следующим образом: f.barbata&gt;f. crinita&gt;f. hoppii.

О некоторых зависимостях численности бентоcных инфузорий от физико-химических свойств донных осадков
Provedor de dados: 13
Autores: Миловидова, Н. Ю.; Кирюхина, Л. Н.; Авдеева, С. У.
В севастопольских бухтах обнаружено восемь таксонов инфузорий, численность которых составляет от 5 до 80 тыс. экз/м2, в среднем 24,5 тыс. экз/м2. Наибольшее разнообразие инфузорий приурочено к  алевритовым илам с высоким  содержанием органического углерода  (2,24—4,16%)  и  небольшим количеством  углеводородов  (0,1— 0,5 г на 100 г осадка). Исследованные  инфузории по-разному  относятся к  физико-химическим свойствам донных осадков. Предполагается, что донные инфузории могут быть индикаторами уровня накопления углеводородов в грунтах.

О суточной ритмике биолюминесценции морских копепод и влиянии  на нее температуры
Provedor de dados: 13
Autores: Евстигнеев, П. В.; Битюков, Э. П.
В условиях естественной  освещенности  у копепод рода Pleuromamma отмечены суточные изменения энергетических параметров  свечения. Интенсивность биолюминесценции P. qracilis максимальна в полночь и  в 1,5 раза превышает ее значение в полдень. При оценке влияния температуры и освещенности на биолюминесцентный сигнал в эксперименте показано, что  повышение освещенности снижает амплитуду вспышек. С увеличением температуры  энергетические  параметры светоизлучения  возрастают. На основании построенной температурной  кривой интенсивности свечения P. gracilis из различных районов  океана определены  оптимальные температурные  условия свечения, реакции светоизлучения.

Autores: Копытов, Ю. П.; Ахметов, А. Ш.
Методом дробнофакторного эксперимента исследовалось в динамике влияние температуры, диспергирования и концентрации нефти  на скорость самоочищения морской воды. Показано,  что  наибольшее положительное влияние на скорость трансформации углеводородов  оказывает начальная концентрация нефти. Увеличение  степени диспергирования нефти оказывало значительно меньшее воздействие на изучаемый процесс. Влияние температуры менялось  во  времени от  положительного в начале  до отрицательного в конце опыта. На основании полученных данных обсуждается вопрос о перспективности использования метода УФ-спектроскопии в санитарно-токсикологических исследованиях.

Autores: SALOMONI, E.; BORBA, E. R.
Tradicionalmente, no Rio Grande do Sul, a criação de bovinos de corte é realizada de forma extensiva em campo natural, sendo que na maioria das propriedades são desenvolvidas as três fases do processo produtivo, que são a cria, recria e engorda. Na engorda, as fêmeas que - por idade avançada, zootecnicamente inferiores ou com problemas - deixam de interessar a reprodução, constituem a categoria de vacas de descarte destinadas ao abate.

Irrigação do feijoeiro.
Provedor de dados: 14
Autores: STONE, L. F.; MOREIRA, J. A. A.
O feijoeiro é sensível tanto à deficiência hídrica como ao excesso d'água. As fases de floração e desenvolvimento das vagens são as mais sensíveis a estes estresses. Nas condições climáticas de Goiânia, o consumo d'água do feijoeiro de inverno, plantado em junho, é de aproximadamente 3 mm/dia, da germinação ao inicio da floração, e de 6 mm/dia desta fase em diante. A irrigação por aspersão tem sido a mais utilizada nas terras altas, embora por sulcos e comugações também sejam empregadas. Nas várzeas, a irrigação por sulcos é a mais usada, embora se possa irrigar o feijoeiro for faixas, por inundação intermitente e por inundação pela elevação do lençol freático.

Controle químico e mecânico da palmeira Bacuri (Pradosia lutexens) em pastagens.
Provedor de dados: 14
Autores: FERNANDES, E.; BOOCK, A.; OLIVEIRA, A. R. de.
Em algumas regiões do Estado de Mato Grosso do Sul, a incidência da palmeira bacuri (Pradosia lutexens) diminui de forma acentuada a produtividade das pastagens, comumente formadas com os capins colonião e jaragua. A invasora tem preferência por solos de elevada fertilidade natural, principalmente, derivados de rochas calcárias, como ocorre na Região da Serra da Bodoquena ou, ainda, por áreas localizadas em vales intermontanos (furnas), cujos solos são de média a elevada profundidade. Foi conduzido um experimento com o objetivo de determinar a eficiência e o custo relativo de várias alternativas de controle da palmeira. A expectativa foi de que o emprego de métodos químicos (herbicidas a base de Picloran ou Dicamba + 2,4,5 T, ou óleo diesel) e mecânicos...

Efeitos de níveis de nitrogênio, fósforo, potássio e magnésio no desenvolvimento de porta-enxertos de seringueira.
Provedor de dados: 14
Autores: PEREIRA, L. V.
A carência de informações sobre doses adequadas e econômicas de fertilizantes a serem aplicados, aliada ao não procedimento de análise química do solo para ajustar os níveis de nutrientes, tem contribuído para o lento e desuniforme desenvolvimento dos porta-enxertos de seringueira e, consequentemente, reduzido o aproveitamento do viveiro, além de retardar o plantio definitivo. Face a esses problemas a UEPAE Rio Branco conduziu um experimento para testar os níveis de nutrientes do solo.

Periodo de monta para o Pantanal Mato-Grossense, sub-regiao do Paiaguas.
Provedor de dados: 14
Autores: TULLIO, R. R.
As fazendas do Pantanal apresentam grandes areas (valor modal de 10.800 ha) com poucas subdivisoes (7,9 +_ 4,8). O manejo imposto ao rebanho e o tradicionalmente utilizado na regiao onde, os touros permanecem durante todo o ano com as matrizes, na proporcao 1:10, apesar de na epoca seca haver uma separacao natural do rebanho. Alem disso, os animais sao pouco manejados, criados sem divisao em categorias, o desmame e tardio e o trato sanitario deficiente. Esses fatores interferem de forma negativa na produtividade do rebanho, principalmente atraves da mortalidade de bezerros no periodo logo apos o parto de uma vez que ocorrem nascimentos durante todo o ano, apesar de haver uma concentracao de nascimentos no ultimo semestre do ano. O objetivo deste trabalho e...

O fungo Cylindrosporium sp., ate o momento, nao foi cultivado em meio de cultura, no entanto, os conidios retirados de crostas colonizadas, quando aplicados em jardim clonal atacado por Phyllachora uberi, propiciaram ao Cylindrosporium uma taxa de colonizacao de aproximadamente 45% das crostas, o que pode ser representativo em termos de reducao do inoculo primario na area. Todavia, acredita-se que esse parasito podera tornar-se importante para o controle do inoculo primario de P. huberi, principalmente se seu cultivo in vitro for viabilizado. Verificou-se tambem que Cylindrosporium sp. pode disseminar-se rapidamente em jardim clonal atacado por P. huberi.

Autores: MIRANDA, J. C. C. de.
Os microorganismos do solo estao presentes em grande numero proximo as raizes das plantas e desempenham um papel importante em numerosos processos fisiologicos, que compreendem a patogenicidade, o saprofitismo e a simbiose. A simbiose mais amplamente observada entre as plantas e a associacao micorrizica, que envolve varios fungos do solo e raizes de plantas superiores. Esta associacao micorrizica, ou micorriza, tornou-se um tema de pesquisa de interesse desde que foi constatada a sua capacidade de proporcionar um aumento da absorcao de nutrientes do solo pelas plantas, principalmente do fosforo. As micorrizas nao aumentam o teor total de nutrientes no solo, mas permitem que a planta explore melhor as suas reservas. Nos olos de baixa fertilidade, a...

Efeito de diferentes coberturas do solo e frequência de irrigação na cultura do alho.
Provedor de dados: 14
Autores: NUNES, M. U. C.
A importância da expansão da cultura do alho no Estado do Acre, e evidenciada pela ausência de produção local, acarretando preços elevados do produto, importado do Centro-Sul do Pais. Devido as condições de solo e clima locais, a irrigação e o controle de temperatura e umidade do solo, constituem importantes fatores que influem no sistema de produção. O alho é uma cultura muito influenciada pelo fotoperíodo e temperatura, sendo recomendável seu plantio no Acre entre abril e maio. Conseqüentemente, seu período de desenvolvimento situa-se na época mais seca do ano, tornando-se obrigatório o uso de irrigação para a suplementação das necessidades hídricas da planta, assegurado máximo vigor e rendimento. O objetivo deste trabalho foi verificar o efeito de...

Produtos químicos e práticas culturais na quebra de dormência da videira.
Provedor de dados: 14
Autores: ALBUQUERQUE, J. A. S. de; SOBRAL, S. M. do N.
Realizaram-se quatro estudos em viveiros da cultivar Italia para a quebra de dormencia da gema na regiao tropical semi-arida do Submedio Sao Francisco: efeito do desfolhamento artificial da videira na brotacao da gema em diferentes epocas antes da poda; efeito do SADH na brotacao da gema apos a poda; efeito do glifosate na brotacao da gema apos a poda; efeito da elimacao parcial e total da brotacao apical e remocao da escama na brotacao da gema. Entre os quatro estudos realizados, somente a emorgacao do ramo associada a remocao da escama da gema obteve resultados satisfatorios em induzir a quebra da gema da videira e, como consequencia, um aumento na producao. Com relacao ao mosto da uva nao houve diferencas estatisticas nos quatro estudos realizados nos...

Criação de tilápias em associação com suínos.
Provedor de dados: 14
Autores: PAGANI, J. A.; COSTA, A. L. da.
No estado do Acre a produção de pescado está concentrada nos municípios de Tarauacá, Cruzeiro do Sul e Sena Madureira. Em decorrência, principalmente, do rio Acre ser pouco piscoso e também da distância e precárias vias de acesso que separam esses municípios da região do Vale do Rio Acre (Rio Branco, Senador Guiomard e Xapuri), a oferta de peixes é bastante reduzida, o que vem obrigando sua importação, principalmente de Boca do Acre e Porto Velho, elevando o preço do produto e, por conseguinte, aumentando o custo de alimentação. Embora o rebanho suíno tenha aumentado nos últimos anos, a suinocultura acreana caracteriza-se por apresentar, na sua quase totalidade, as chamadas criações de "fundo de quintal", onde os animais são criados extensivamente, sem...

Tensão da água do solo e produtividade do arroz.
Provedor de dados: 14
Autores: STONE, L. F.; MOREIRA, J. A. A.; SILVA, S. C. da.
A baixa capacidade de retenção de água dos solos, aliada a alta demanda evapotranspirativa, faz com que os veranicos causem sérios decréscimos na produtividade do arroz, provocando oscilações na produção nacional. Uma das alternativas para a solução deste problema é o uso da irrigação suplementar. Com isto, além do aumento na produtividade do arroz, é possível utilizar o equipamento de irrigação para outros cultivos (trigo e feijão, por exemplo) na entressafra. A irrigação por aspersão é indicada para solos de alta permeabilidade e de baixa capacidade de retenção de água, como a maioria dos solos da região dos cerrados.

Influência do porta-enxerto sobre a produção de tomate (Lycopersicon esculentum).
Provedor de dados: 14
Autores: NUNES, M. U. C.
O tomate é um dos produtos hortícolas mais consumidos no Estado do Acre, tornando-se de grande importância na dieta alimentar de população acreana. Nas condições de clima tropical úmido, a bactéria, Pseudomonas solanacearum, agente causal da murcha bacteriana, constitue um grande obstáculo ao desenvolvimento da planta e a produção do tomateiro. Nas condições ambientais, com alta temperatura e umidaoe relativa, ocorre grandes perdas, atingindo até 100%, dependendo do índice de infestação no solo. Visando minimizar o problema da cultura, a UEPAE de Rio Branco desenvolveu este trabalho com o objetivo de verificar a existência de solanáceas compatíveis com o tomateiro e que possam ser utilizadas como porta-enxerto, garantindo maior produção e melhor qualidade...

Considerações sobre os princípios tóxicos da mandioca.
Provedor de dados: 14
Autores: OLIVEIRA, F. N. S.
A mandioca (Manihot esculenta Cranz) encerra possibilidades de resolver um dos grandes problemas enfrentados pelos pecuaristas de Rondônia, o da alimentação animal durante a estação seca. Entretanto, seu emprego no balanceamento de rações ainda não é visto como de grande importância em razão de sua utilização mais acentuada como alimento energético para o homem. Além desse aspecto, seu aproveitamento está limitado, principalmente, pela ação dos glicosídeos cianogênicos com alto grau de toxicidade para homens e animais. Entre as plantas cultivadas, a mandioca é a que encerra maior quantidade dessas substâncias. Objetivando inspirar maior confiança nos produtos derivados da mandioca (fins alimentícios e forrageiros), este trabalho visa elaborar alguns...

Erosao e praticas conservacionistas nos cerrados.
Provedor de dados: 14
Autores: DEDECEK, R. A.
Uma agricultura intensiva e permanente depende muito do equilibrio entre perdas e ganhos de nutrientes. Os ganhos sao representados pela adubacoes quimicas e organicas e incorporacao da resteva, e as perdas, pelo cultivos, lixiviacao, volatilizacao e erosao. A erosao nao e seletiva quimicamente, nao produzindo concentracoes diversificadas de nutrientes entre o sedimento e o solo que o formou (tabela 1). A selecao ocorre no maior arraste da materia organica e das particulas mais finas do solo, que sao as armazenadoras dos nutrientes. Os menores teores de nutrientes no tratamento solo descoberto devem-se ao fato de que este recebeu apenas adubacao corretiva de P e K, alem da calagem, em 1977, tendo sido mantido sem vegetacao desde entao e preparado todos...

Autores: GOEDERT, W. J.; REIN, T. A.; SOUSA, D. M. G. de.
A solubilizacao dos fosfatos naturais brasileiros e uma necessidade, em face da baixa eficiencia agronomica dos mesmos. No brasil, os produtos de transformacao mais comuns sao os superfosfatos e fosfatos de amonio, os quais se constituem em fontes de comprovada eficiencia agronomica. Contudo, ha necessidade de se obter produtos com tecnologia mais simples e que melhor aproveitem as materias-primas disponiveis no Pais. Uma das opcoes exercitadas no momento e a producao de fosfatos parcialmente acidulados com acido sulfurico. A eficiencia agronomica dessas fontes, para culturas anuais, tem sido proporcional a fracao da apatita solubilizada. Trata-se, assim, de um produto viavel, se o preco de mercado for estabelecido em funcao do teor de P2 05 soluvel....

Produtividade de cultivares de alface (Lactuca sativa L.) durante a época seca no Acre.
Provedor de dados: 14
Autores: NUNES, M. U. C.
A alface, originária da Ásia, é urna cultura bastante antiga e a mais importante do grupo das hortaliças de folha, sendo amplamente conhecida e cultivada em quase todos os países. Esta hortaliça é típica de climas amenos de elevada altitude, sendo de grande importância para o deu desenvolvimento a temperatura noturna amena. As temperaturas maiores que 249C, aceleram o desenvolvimento do pendão floral, o que diminui a qualidade da alface, devido ao acúmulo de látex amargo no sistema vascular da planta. Alface de qualidade superior, é produzida em clima ameno e altitudes superiores a 900m. Atualmente existem cultivares mais adaptadas a climas quentes e a baixas altitudes. A seleção de cultivares para condições climáticas, é de real importância para o sucesso...

Reune informacoes relativas a pratica da irrigacao no feijoeiro. Mostra a sua influencia na produtividade da cultura e destaca a necessidade de sua utilizacao, diante da deficiencia de agua no solo, originada das incertezas do clima nas epocas tradicionais de plantio. Discute em detalhes as reacoes do feijoeiro a periodo de deficit e de excesso de agua. Indica as fases criticas e as necessidades totais e parciais de agua. Sao descritos os criterios que, pela simplicidade de aplicacao e maior ocorrencia de resultados experimentais, permitem decidir o momento de irrigar e quantificar os volumes de irrigacao. De alguns metodos de irrigacao, entre os com possibilidade de serem usados no cultivo do feijao (irrigacao por sulcos e por aspersao), definem-se...

Produtividade de cultivares de alface (Lactuca sativa L.) sob cobertura plástica e em campo aberto no Acre.
Provedor de dados: 14
Autores: NUNES, M. U. C.
A utilização de plástico na agricultura teve inicio nos anos quarenta, nos Estados Unidos, depois no Japão, Itália, França e outros países. A plasticultura nesses países tem se difundido de tal forma que atualmente se constitui em um complemento indispensável e tem revolucionado algumas práticas culturais tradicionalmente empregadas. Em alguns países como no Japão, a plasticultura encontra seu campo de aplicação independente do clima, tipo de cultura e demais fatores. No Brasil, país de vocação agrícola, com terras férteis e possuidor de diversos tipos de clima, a produção de hortigrangeiros com a utilização de plástico, poderá tomar impulso, com significativo aumento de produção por área, redução de mão-de-obra e dos gastos de insumos, proporcionando...

A cultura da mangueira: práticas de cultivo.
Provedor de dados: 14
Autores: SAMPAIO, J. M. M.; RODRIGUES, J. A. S.
As áreas de melhor adaptação para mangueira são aquelas onde as estações secas e chuvosas são bem defini das. O período seco deve ocorrer bem antes do florescimento, a fim de permitir um período de repouso vegetativo á planta, e prolongar-se até a frutificação para evitar os danos causados pelo ataque da antracnose e do oídio. Após frutificação, é benéfica a ocorrência de chuva afim desestimular o desenvolvimento e impedir a queda dos frutos. A quantidade de chuva pode variar entre 500 e 2.500mn anuais, desde que atendidas as condições referidas acima.

Uma série de fatores ambientais, associados principalmente ao manejo e à alimentação, é preponderante para o adequado desempenho reprodutivo de bovinos de corte. Sob regime de pastejo direto, entretanto, o desempenho dos animais é uma função dependente da quantidade e da qualidade da pastagem, associada ao manejo dispensado às diferentes categorias, conforme suas necessidades e objetivos. Alguns fatores de ordem não genética também afetam a produção animal e, em especial, o desempenho reprodutivo, tais como a idade ao primeiro serviço, época e período de acasalamento, idade de desmame e condição reprodutivada matriz, entre outros. É pois, neste sentido que será conduzido o raciocínio a ser desenvolvidodurante a exposição dos resultados colhidos ao longo de...

Selecionaram-se solanaceas nativas imunes a murcha bacteriana do tomateiro, de modo a utiliza-las como porta-enxerto. Porem, so foi possivel adquirir-se sementes viaveis de quatro solanaceas rusticas. Com isso, resolveu-se avaliar cultivares e linhagens de tomate que vem sendo desenvolvidas para resistencia a murcha, alem de outras de habito determinado, as quais, em geral, apresentam-se mais resistentes a doenca. Dentre as treze solanaceas testadas, apenas o cubiu e a jurubeba vermelha mostraram-se imunes a murcha.

Manejo de pastagens nativas de área de cerrado do Amapá com uso de fogo.
Provedor de dados: 14
Autores: SOUZA FILHO, A. P. da S.; PIMENTEL, D. M.; MEIRELLES, P. R. de L.
Com o advento do período de estiagem, 3 a 4 meses, que anualmente ocorre no Amapá, as pastagens nativas que compõem as extensas áreas de campo cerrado ficam bastantes secas, induzindo os pecuaristas que ocupam estas áreas a lançarem mão do uso do fogo, como prática de manejo, visando principalmente, eliminar o material morto resultante da estiagem e melhorar a qualidade da forragem produzida nos primeiros meses da estação chuvosa. Porém a utilização indiscriminada do fogo como se vem verificando na região, pode estar contribuindo decisivamente para a diminuição da potencialidade destas pastagens, reduzindo o vigor e a frequência de gramíneas desejaveis e ensejando o aparecimento de espécies indesejaveis, geralmente mais resistente ao fogo.

Autores: NUNES, M. U. C.; MOURA, G. de M.
A incorporação de leguminosas no estadio de floração visa principalmente o aumento de matéria orgânica e nitrogênio. Essa prática beneficia as propriedades físicas, químicas e biológicas do solo, propiciando na maioria dos casos aumento de produtividade da cultura, a seguir implantada. A adubação verde no período da entressafra proporciona maior controle da erosão e da infestação de nematóides, melhora a retenção de água e adubos químicos no solo, controla as plantas daninhas e plantas hospedeiras de pragas e doenças, além dos benefícios acima citados. Em consequência reduz a utilização de insumos como herbicidas, inseticidas, fungicidas, nematicidas e fertilizantes.

Autores: SANZONOWICZ, C.; GOEDERT, W. J.
A eficiencia de uma fonte de fosforo esta relacionada as suas caracteristicas, mas tambem depende do tipo de solo e do comportamento da especie vegetal. Os fosfatos naturais brasileiros so de baixa solubilidade e de dissolucao lenta. A eficiencia agronomica inicial e baixa, aumentando com o passar do tempo. A decisao sobre a viabilidade do uso dos fosfatos naturais brasileiros para pastagens nao pode ser generalizada; contudo, os resultados experimentais mostram que a utilizacao dessas fontes torna-se viavel desde que a estrategia de manejo seja adequada. Nesse aspecto, merecem destaque a escolha da especie forrageira, da dose e do modo de aplicacao do fosfato, do tipo de solo e da relacao de precos da unidade de fosforo total na forma de fosfato natural...

Efeito de diferentes níveis populacionais de Cerotoma sp. no rendimento do caupi (Vigna unguiculata (L.) Walp).
Provedor de dados: 14
Autores: FAZOLIN, M.
A cultura do caupi vem se tornando uma opção promissora aos produtores devido à sua satisfatória produtividade e rusticidade, com boa adaptação às condições ambientais da Região Amazônica. Dentre as pragas que atacam esta cultura, destacam-se as vaquinhas, em especial as do gênero Cerotoma que, durante todo o ciclo da cultura consomem as folhas das plantas perfurando-as e, em casos mais severos de ataque, destruindo-as por completo. A UEPAE Rio Branco desenvolveu um experimento com o objetivo de avaliar qual a forma de manejo mais adequada desta importante praga da cultura para os estados da Amazônia.

Principais cultivares de mandioca indicadas para o Centro Sul.
Provedor de dados: 14
Autores: BUENO, A.
A baixa prioridade dada ao melhoramento genetico da mandioca, ate antes da criacao da EMBRAPA, resultou na geracao de um pequeno volume de resultados aplicados, e em poucas contribuicoes sobre estudos basicos. Merece destaque a contribuicao do Instituto agronomico de Campinas (IAC), em Sao Paulo, que desenvolveu varios clones de mandioca que tiveram ampla disseminacao em varias regioes produtoras daquele estado. A contribuicao mais importante, deixada pelos primeiros programas de melhoramento de mandioca, foi a identificacao das principais cultivares nativas ou introduzidas em cada regiao. Mas como os recursos eram escassos, na epoca, os testes de avaliacao foram limitados em numero e beneficiaram apenas poucos locais em cada regiao geografica,...

Autores: BERTAUX, S.; BARON, V.; ANJOS, J. B. dos.
A transferência da tecnologia dos Chassis polivalentes à indústria brasileira foi possível através da avaliação e adaptação de equipamentos e implementos agrícolas. O arado de duas aivecas foi projetado para coplar-se ao chassi do policultor-600 ou ao do multicultor-6H, fabricados respectivamente pela CEMAG S/A (Fortaleza, CE) e TORNEP (Porto Alegre, RS). Esse arado proporciona um gasto menor de tempo no preparo inicial do solo (aração) porque tem uma junta de bois, que tracionando uma só aiveca, trabalha com reserva de potências capaz de ser transformada em trabalho útil.

Competição de cultivares e hibridos de repolho no Território Federal do Amapá.
Provedor de dados: 14
Autores: SEGOVIA, J. F. O.; COSTA JUNIOR, R. C.
O repolho, assim como a maioria das hortaliças comercializadas em Macapá, são quase que totalmente importadas de outros produtores do país, sendo Belém do Pará, a sua principal fonte de abastecimento. Esta intermediação, acrescida do frete de transporte, contribui substancialmente para elevação do preço do produto no mercado local. Dentre os fatores responsaveis pela baixa produção desta importante hortaliça no Amapá, destaca-se a falta de cultivares adaptadas as condições climáticas locais. Visando avaliar o comportamento e produtividade de diferentes genotipos desta planta, a EMBRAPA, através da UEPAT de Macapá, vem conduzindo, em solo de área de mata de terra firme, experimentos em dois períodos do ano (chuvoso e seco).

Autores: CAVALCANTE, E. da S.
Visando a identificação de cultivares de milho adaptados a área de várzea do Amapá, foram conduzidos 2 ensaios sucessivos (dois cultivos), em solo Gley Pouco Humico hidromorfico, no município de Mazagão. O primeiro foi instalado em julho de 1983 (período seco) e o segundo em dezembro do mesmo ano (período seco) na mesma área. Utilizou-se um delineamento experimental do tipo blocos ao acaso com 16 tratamentos (cultivares estudadas) e 4 repetições. O espaçamento foi de 1m entre linhas e 0,4m entre plantas. Após o desbaste, feito 20 dias depois da semeadura, foram mantidas 2 plantas por cova, os ensaios foram conduzidos sem o uso de fertilizantes e corretivos. Os resultados revelaram que as maiores produtividades foram sempre obtidas na época seca e as...

Dentre as alternativas brasileiras para o aumento da producao nacional de graos, tanto para atendimentos do mercado interno como para exportacao, a regiao dos Cerrados do Brasil ja desempenha papel de destaque. A estagnacao da producao nacional de cereais, notadamente nos ultimos anos, decorrencia de frustacoes climaticas na regiao sul do Pais, com perdas substanciais de safras, demonstra claramente a necessidade de diversificacao espacial na producao agricola. Nesse contexto o aumento da oferta de alimentos a nivel nacional, atraves de intensificacao da agricultura nos Cerrados, visando principalmente ao aumento vertical da producao, se apresenta como grande alternativa da sociedade brasileira.

Autores: SOARES, J. M.
A irrigação por aspersão e uma maneira prática de aplicação de água no solo para qualquer cultura ou solo. Um sistema de irrigação por aspersão pode aplicar água no solo em intensidades iguais ou menores que a sua velocidade de infiltração, além da possibilidade de ser manejado automática ou manualmente. Em geral, a irrigação por aspersão pode ser empregada em muitas condições de solo e topografia e em áreas onde a irrigação por superfície apresenta-se ineficiente e dispendiosa. O aspersor e a parte mais importante do sistema de irrigação por aspersão. Uma ampla classificação em tipos de aspesores e bocais permite ao projetista selecionar o aspersor apropriado e a pressão de serviço para satisfazer um solo específico e/ou requerimento da cultura.

Determinacao de metodos de mecanizacao agricola recomendaveis aos pequenos produtores rurais do semi-arido, testaram-se, pelo terceiro ano consecutivo, varias tecnicas. A ultima foi realizada de janeiro a marco de 1985, atraves de um experimento em nivel de campo, com seis tratamentos, representados pelos diferentes sistemas de mecanizacao agricola e tracao animal. Os seis sistemas de cultivo testados foram: o "plano", o "plano e sulcamento", o "sulco barrado", "sulcamento", "sulcamento barrado", "camalhoes inclinados" e "aracao parcial". o plantio dos quatro primeiros foram feitos com plantadeira-adubadeira SANS montada sobre o policultor 1500 (duas linhas plantadas-adubadas simultaneamente). Nos dois ultimos usou-se a matraca e a adubacao foi manual.

Testes agronômicos no meio real: um elemento de diagnóstico para a pesquisa e a extensão rural.
Provedor de dados: 14
Autores: VALLÉE, G. J. A.; MIRANDA, E. E. de; DORASWAMY, G.
Os sistemas tradicionais da produção agrícola do Nordeste devem evoluir rapidamente para evitar que a, cada ano, cresca a migração dos agricultores para as cidades ja superlotadas. Um caminho para tentar solucionar este problema consiste em associar os pequenos produtores rurais em busca de soluções ou alternativas técnicas. Estas deverão ser testadas nos campos dos produtores e em várias situações, afim de integrar as heterogeneidades que a pesquisa, dentro de seus campos experimentais, não pode avaliar. Este trabalho inclui a análise de uma experiência realizada nos campos de produtores em Ouricurí, PE, no ano de 1982-1983. A primeira parte discute a importância agronômica e econômica da introdução de novas técnicas, utilizando o critério da Taxa Interna...

Autores: PORTELLA, J. A.; FAGANELLO, A.; SATTLER, A.; NEDEL, J. L.; ANNES, H. de O.
Visando atender às necessidades da pesquisa em experimentação e multiplicação de sementes, foi projetada, construída e testada, no ano de 1985, uma semeadora para plantio direto de parcelas. O projeto diferencia-se, consideravelmente, dos demais conhecidos, tanto na construção, quanto ao modo de operação dos controles. A máquina é de fácil manobra, simples de trabalhar, sendo que os controles ficam próximos do operador. Os ajustes de densidade de semeadura, do tamanho de parcela, da profundidade de semeadura e da vazão de adubo são rápidos, precisos e fáceis. A caixa de sementes e o sistema de distribuição são autolimpantes, com reduzida possibilidade de mistura varietal. A semeadora permite, ainda, variação do número de linhas, espaçamento entrelinhas e...

Autores: LEAL, J. A.
A pecuaria leiteira no Brasil é explorada em regiões desfavoraveis a atividade, sendo a suplementação a base de volumoso a mais econômica, embora não seja a mais eficiente em termos de produção. Fundamentada nesse principio, a EMBRAPA-UEPAE de Teresina desenvolveu um trabalho de suplementação de volumosos para vacas em lactação mantidas em regime de pastagem utilizando-se como fonte de suplementação: capim-elefante, silagem de sorgo e feno de parte aerea de mandioca. Dos alimentos volumosos utilizados na época seca, o capim-elefante ocupa lugar de destaque com uma produção media de leite (kg/vaca/dia) de 5,9 e quando acrescentado de feno a produtividade foi de 6,3. Com a suplementação de silagem de sorgo, entre outubro de 1983 e fevereiro de 1984 a...

Avaliação da fertilidade de dois solos do Estado do Acre, em casa de vegetação.
Provedor de dados: 14
Autores: ALVARENGA, M. I. N.
Com uma imigração constante e crescente, a ocupação do estado do Acre tem sido feita em ritmo acelerado. Este crescimento desordenado tende a se agravar, na medida em que áreas que estão sendo ocupadas são, praticamente desconhecidas no tocante ao potencial dos solos, já que os estudos desta região se restringem, na maioria dos casos, a poucos trabalhos de revisão baseados em imagens de radar, ou seja, são informações apenas aproximadas. Assim. a UEPAE Rio Branco conduziu um experimento com o objetivo de avaliar a fertilidade de um Latossolo Vermelho Escuro (LE) e de um Podzólico Vermelho Amarelo (PV), e sugerir técnicas de manejo de adubação mais econômicas para estes solos, que ocorrem com frequência na região.

Eficiência comparativa de inseticidas no controle das pragas do arroz armazenado no Estado do Acre.
Provedor de dados: 14
Autores: FAZOLIN, M.
No Brasil, as perdas de grãos durante o armazenamento têm atingido níveis médios de 20%. No Acre, devido as precárias condições de armazenamento e os fatores climáticos favoráveis ao desenvolvimento das pragas, os níveis de perdas são superiores a 30%. Os insetos têm sido os agentes responsáveis por essas perdas, causando prejuízos quantitativos determinados pela perda de peso e prejuízos qualitativos causados pela depreciação do produto devido a presença de ovos, larvas, pupas, adultos e alterações na composição química do produto, além de facilitar o desenvolvimento de micro-organismos. Nas condições locais, 35% do arroz armazenado é atacado pelo gorgulho (Sitophilus zeamais) e 65% pela traça (Sitotroga cereealella). No controle dessas pragas alguns...

O objetivo do presente trabalho e fornecer uma apresentação gráfica do uso pratico do equilíbrio higroscópico baseado na teoria do potencial da água. A metodologia de calculo baseou-se no modelo simplificado de equilíbrio higroscópico descrito por CAMPELO JUNIOR (2). As curvas correspondentes a diversas umidades de arroz, milho, soja, assim como de potenciais escolhidos arbitrariamente foram locadas em gráficos psicrométricos. Uma das informações praticas obtidas a partir dos gráficos e a determinação do aumento de temperatura para secagem de grãos em silos ou barcaças a baixas temperaturas. Verificou-se que as umidades indicadas para armazenagem de arroz, milho, e soja correspondem ao potencial de - 127 atm.

Foi constatado, no Campo Experimental do CNPSD, um fungo Ascomiceto, Dothideaceae, identificado como Rosenscheldiella sp., formando estromas escuros na face abaxial de foliolos de seringueira no estagio D. A doenca tem sido denominada de "falsa crosta negra", quando isolada em folhas, ou "complexo crosta negra", quando associada a crostas de Phyllachora huberi. Ate o momento, tem sido verificado que Rosenscheldiella sp. so coloniza tecidos previamente infectados ou inicialmente colonizados por P. huberi. O controle dessa doenca pode ser feito com apenas duas pulverizacoes, a intervalos de dez dias, com a mistura de alguns fungicias.

Resultados de pesquisa demonstraram que em Ouro Preto e Ariquemes-Rondonia, as maiores producoes de MS sao obtidas com corte a 10 e 20cm e 25 e 30cm acima do solo, respectivamente, enquanto que em Presidente Medice-RO a altura de corte nao afetou a producao de MS, contudo, visando asssegurar maior persistencia da capineira, recomenda-se corte acima de 10cm. Cortes e baixa altura (5 e 10cm) implicam na reducao dos stands e em incremento da infestacao de invasoras. Nos tres locais, a altura de corte nao influenciou os teores de PB da forragem.

Em 1994, na Estacao Experimental da UEPAE Porto Velho e em areas de produtores, plantas de seringueira apresentavam rachaduras na regiao do coleto. No local afetado havia acumulo de latex coagulado e o tecido necrosado atingiu a casca e, consequentemente, os vasos laticiferos, sem, contudo, danificar o lenho. O diagnostico de laboratorio revelou nao existencia de microrganismos patogenicos e inicio de cicatrizacao natural dos tecidos, descartando a possibilidade de doenca. O problema parece ser de ordem fisiologica, pois o porta-enxerto sofreu rachaduras e exsudacao do latex, o mal nao foi seletivo. Tal fato poderia ser explicado pelo acrescimo do volume de producao do latex em periodo chuvoso. Recomenda-se inspecao periodica nos seringais e pincelamento...

Préparation de crevettes (Pandalus borealis) cuites décortiquées en saumure. Intérêt de l'ionisation préalable des crevettes et de l'incorporation d'acide benzoïque dans le produit fini.
Provedor de dados: 5
Autores: Vallet, Jean-luc; Cornet, Josiane; Knockaert, Camille.
Chaque année, plus de 400 tonnes de crevettes Pandalus borealis sont importées du Danemark, soit sous forme congelée, soit pour l'essentiel préparée en saumure. Dans la majorité des cas, les sociétés françaises importent ces produits pour une revente directe, ou éventuellement après reconditionnement en contenants plus petits et étiquetage à leur marque. De par la réglementation, aucune société française n'est actuellement en mesure de fabriquer de tels produits. En effet cette préparation en saumure est une semi-conserve à entreposer au froid (+ 4°C) qui fait appel, outre à l'acide citrique, à l'acide benzoïque et parfois à l'aeide sorbique pour assurer une conservation de 4 à 9 semaines. En France l'acide benzoïque est autorisé pour la seule conservation...

Hydrosedimentological processes and soils of the barito estuary (south-kalimantan, indonesia)
Provedor de dados: 5
Autores: Bassoullet, Philippe; Djuwansah, R; Gouleau, D; Marius, C.
A pluridisciplinary study was carried out in the south-eastern part of Kalimantan (Indonesia) in a deltaic area close to Banjarmasin town. Upstream from Banjarmasin, Barito river divides into two branches, one of which meets the Kapuas river slightly further to the west, to form the Kapuas Murung estuary. This programme is designed to increase knowledge about the physical and sedimentological processes, physical and chemical properties of the soils, and hydrological and chemical parameters of the Barito estuary. Barito estuary was chosen for two main reasons. First, it constitutes an important waterway for the region, on which Banjarmasin harbour is located; second, the management of the sparsely occupied coastal areas is becoming a priority. The...

La pêche au vivaneau en Guyane française
Provedor de dados: 5
Autores: Prevost, Etienne.
Traditionally fished by line and conical fishing basket by Venezuelan ships, the red snapper resource off the coast of French Guyana (fish belonging to the Lutjanidae family) has been experiencing intensive fishing since 1984-85 due to the boom in classic fishing techniques and the development of trawl fishing.  The study evaluates the situation of this resource's potential: biology, sampling data, bio-statistics (size and sex), size-weight relationship of the three species, specific composition of the catches, describes fishing devices and prospecting, pinpoints fishing spots, gives a distribution of the Venezuelan and Martinique fishing effort.

The circulation of norwegian sea overflow water in the eastern north-atlantic
Provedor de dados: 5
Autores: Harvey, Jg; Theodorou, A.
Neutral surfaces are defined from historical hydrographie data on which the spreading of Iceland-Scotland overflow water (ISOW) may be examined in the eastern North Atlantic and the lrminger Basin. Each of these neutral surfaces occurs at less than 400 rn on the Iceland-Faroe rise, but they descend to depths in excess of 2 600 rn (shallowest) and 3 600 rn (deepest) in the area of study. Salinity distribution on these surfaces provides a first indication of circulation patterns. e-S water mass analysis, using successive mixing stages of ISOW is generally found to be satisfactory, but in the south-eastern part of the region a third water mass characteristic is required. Oxygen data from cruises between 1957 and 1962 are re-examined and, after the...

Influence du climat sur le recrutement et sur la production d'huîtres cultivées (Crassostrea angulata et Crassostrea gigas) dans le bassin de Marennes-Oléron (France)
Provedor de dados: 5
Autores: Heral, Maurice; Deslous-paoli, Jean-marc; Prou, Jean.
Recruitment, marketed yield and cultivated biomasses of oysters Crassostrea angulata and Crassostrea gigas are compared to climatic indices for the period 1885-1984. Temperature plays a role up on the date of spawning but explains only partially the failure of recruitment, which has less influence on the marketed yield than on the total biomass Contrary to the sensitivity of wild molluscan stocks to climatic conditions, yield and biomass of these cultivated stocks are not hightly correlated to the annual and seasonal indices of rainfall and air temperature.

Contrairement à 1983 et 1984, le bloom printanier à diatonées Skeletonema costatum ne s'est pas manifesté en 1985 par une coloration marron des eaux superficielles, certains facteurs ayant été défavorables de la mi-mars à la mi-avril : températures basses, vents modérés et forts abondants, mer agitée à très forte. Le bloom estival à Thalassiosira sp. et Rhizosolenia delicatula apparu fin mai a été favorisé par l'importante pluviosité de la mi-mars à la mi-avril, l'élévation de température de fin mai et début juin, la faible agitation de la mer et la dominance des vents calmes, faibles et modérés en mai et juin. Ce bloom cessera, fin juin, en grande partie sous l'action des vents qui agiteront la mer, cassant ainsi la stratification thermo-haline établie.

Amélioration de l'évaluation des stocks de mollusques cultivés en Charente- Maritime
Provedor de dados: 5
Autores: Bacher, Cedric; Deslous-paoli, Jean-marc; Heral, Maurice; Prou, Jean.
The expansion of shellfish culture businesses (oysters, mussels, clams...) gives way to a competition for the use of limited food resources, especially in the Marennes-Oléron basin where water circulation is slow. Increasing the amount of cultivated molluscs leads, from a biological point of view, to:- a drop in growth performances- a rise in chronic mortalities, higher and higher, due to a weakness in the physiological state with a lack of stocks which would have compensated the habitat seasonal shortages (end of winter, etc...)- a greater weakness to diseases, linked to a deficient physiological state and a density rise which increases the proximity rate and thus, parasite propagation speed.For these primary reasons, and for the future of oyster culture,...

Growth of the japanese oyster, Crassostrea gigas was monitored during 4 years, by following the recruitment of the year 1978, held in rearing conditions. After three and half years, the average length was la cm and the average total weight was 80 g. Clear seasonal changes were observed on the growth in length and weight.  An  important loss in dry weight occured in July, during the release of gametes. Such losses constituted 29 %, 43 % and 60 % of the dry weight, respectively for individuals which were 2 years, 3 years and 4 years old. The higher instantaneous growth rates  (G) were observed during spring and at the beginning of summer. Growth model of Von Bertalanffy, gave the best estimate for the length growth of the species. During the 1979-1982...

Preparation d'un plan d'exploitation de la pecherie de petits pelagiques au Maroc dans la zone centre- atlantique : analyse bio-economique de la pecherie
Provedor de dados: 5
Autores: Meuriot, Eric.
Like other large fisheries of small pelagics in the world, the Moroccan fishery of the Central Atlantic can be considered as a "fishery at risk" insofar as a collapse of the stock is a possibility that cannot be completely ruled out. Unfavourable modifications to the natural environment aggravated by a too intensive exploitation of the resources can bring on such a collapse.  Up until the beginning of the 80s, the level of exploitation of the sardine stock in the Central Atlantic area remained moderate. This moderation is more a reflection of the profitability constraints that the seine fleet is experiencing than a deliberate choice, except as far as foreign ships are concerned.  The opening of the port of Tan Tan since the end of 1981 is likely to make...

La conchyliculture en Italie. Mission du 1er au 15 juin 1986. Etude Aquaculture Méditerranée
Provedor de dados: 5
Autores: Paquotte, Philippe.
HISTORIQUE : L'élevage des mollusques est une activité très ancienne en Italie. Les sites traditionnels de cette activité étaient la Rade de la Spezia, le Lac Fusaro près de Naples, la "Mar Piccolo" de Tarante et la Lagune de Venise (voir figure l).Il s'agissait autant d'ostréiculture (huître plate Ostrea edulis) que de mytiliculture (Mytilus galloprovincialis). Le déclin de l'ostréiculture au profit de la mytiliculture date du début du siècle et s'est accentué après la seconde guerre mondiale. En dehors de quelques opérations d'affinage ou de retrempage, on peut considérer que l'ostréiculture est une activité abandonnée en Italie et la production d'huîtres provient exclusivement de la pêche sur des bancs naturels (huître plate Ostrea edulis et huître...

Analyse du déclin de la pêche artisanale à St Pierre et Miquelon
Provedor de dados: 5
Autores: Eynaud, P.
Studying the reasons behind the decline in small-scale fisheries at Saint Pierre and Miquelon (SPM) requires assessing this decline. Between 1950 and 1985, the number of vessels utilised in small-scale fisheries dropped by a factor of seven and the mean age of fishers increased by 13 years. Individual catches have nevertheless remained stable and have even increased slightly since 1963. Can it be deduced that the crisis in small-scale fisheries is only due to a problem of fish stocks and the adjustment of the number of fishers to stock availability? Must the causes of decline be sought in the development of industrial fisheries? In the increase in costs? Or in market studies? By placing SPM in its geographical and historical context, these questions take...

Autores: Deslous-paoli, Jean-marc; Heral, Maurice.
In the bay of Marennes-Oléron, the shell represents 60% and the dry flesh from 3 to 8.5% of the total weight of Crepidula fornicata. Seasonal changes in the biochemical composition of the dry flesh show two periods of spawning for the females and a single period of reproduction for the males, and that the main component of the energy reserve is glycogen. The mean energy value of Crepidula fornicata varies between 15.1 and 19.3 joules/mg of ash-free dry weight of flesh (average 17.7) and this value is higher in the males than the females, during aIl the periods of reproduction. The females lay, as early as their third year, about 56 egg capsules at each spawning, containing a total of Il 725 eggs with an energy value of 22.4 joules/mg ash free dry weight.

Fishing fleet replacement. The French policy from 1945 to 1983
Provedor de dados: 5
Autores: Meuriot, Eric.
(Not controled OCR )The author describes the French fishing fleet replacement policy from 1945 to 1983 and ascertains from it the objectives and constraints of public policy. While the theoretical and practical negative effects of open-access fisheries were well assessed, the French experience provides an example of the difficulties of carrying out a policy limiting access to fisheries. Domestic conflicts of interest and open competition with foreign countries failed to limit the overall fishing capacity of the French fleet. They have also led the government to focus on shortterm distributional issues rather than on long-term efficiency. It is the author's opinion that similar case studies could be useful for understanding the evolution of the fishing...

A new process of collecting fIat oyster spat in deep water, based on the use of suspended mussel shell, was perfected between 1978 and 1982. The technique has contributed the continued breeding of the species in Quiberon bay (Brittany ) , in spite of the presence of Bonamia ostreae. In order to quantify the number of spat recruited by this technique each year, a method of estimation was tested during the summer 1985. This paper describes the sampling strategy and the results.

Du Golfe du Lion à l'étang de Thau Tribulations d'une huître indigène (1° partie)
Provedor de dados: 5
Autores: Fauvel, Yves.
Among the Greeks and Romans, "the extraordinary gastronomic reputation" of oysters was brought to light by many authors (1). It was also the case among the Gallo-Roman people among whom the consumption of molluscs was widespread since it extended to regions quite far from the areas of production. The problem of transporting while keeping them properly preserved seems to have been resolved by original processes, the complete ingenuity of which we have yet to discover. If some authors, such as Professor Locard, speculate that the oysters were transported in containers of seawater kept at a low temperature by means of ice, others, such as Mr Clouet, lean towards the use of relay station holding tanks built into the ground. One way or another, it is certain...

Dynamiques des productions et des biomasses des huîtres creuses cultivées (Crassostrea angulata et Crassostrea gigas) dans le bassin de Marennes-Oléron depuis un siècle
Provedor de dados: 5
Autores: Heral, Maurice; Deslous-paoli, Jean-marc; Prou, Jean.
The evolution of the production of cupped oysters is estimated on a century (1885-1985) with three different sources of data. The total biomass in culture is calculated from productions by knowing regularly the growing rate and the mortality rate of the populations of oysters. It appears that the efficiencies of the culture (P/B) decrease when the stock increase. The production reaches a plateau maximum of 40 000 tons whereas the stock goes on to growth up to 200 000 tons. This plateau correspond to the maximal capacity of production of the ecosystem limited by the trophic capacities of the bay.

Incidence de la diminution des débits de la Charente sur la production primaire du bassin de Marennes-Oléron
Provedor de dados: 5
Autores: Ravail, Brigitte; Heral, Maurice; Razet, Daniel; Robert, Jean-michel.
Le suivi bi-mensuel des caractéristiques des eaux de l'estuaire de la Charente met en évidence les fortes teneurs en sels nutritifs transportés par ce fleuve. Les apports de fin d'hiver en nitrates sont supérieurs à 240 µ atg N 1(1). Le phosphore a un comportement particulier puisqu'en période de crue, il s'adsorbe sur les particules et le sédiment, jouant un effet régulateur, ainsi les aports ne dépassent guère 2 µ atg P 1(1) en hiver mais aussi en été. Les biomasses phytoplanctoniques vivantes ou dégénérescentes sont fortes avec deux périodes defflorescence bien marquées, mai-juin et octobre. Les teneurs en chlorophylle a atteignent è µg de chla pour la surface et 23 µgde chla pour le fond. Par ailleurs, les teneurs en phéopigments dépassent 31 µg de...

Risk, market imperfections and the growth of an aquacultural firm
Provedor de dados: 5
Autores: Gates, J.m.; Gilly, Bernard.
(Not controled OCR) Economic literature is replete with discussions of risk, market imperfections and firm growth ; often as separate topics. A discussion of risk must inevitably mention Frank Knight's classic contributions to the topic and his dichotomy between risk and uncertainty. Subsequent work has blurred this distinction by introducing subjective probability and expected utility maximization. Subsequent work has also shed doubt on the validity of the expected utility hypothesis in willingness to pay gambles and yet sustained it in the context of aggregate market behavior and "testable hypotheses" (Knez, et al, 1985). to this vast and complex literature we do not aspire to contribute much that is new. Instead we will attempt to apply concepts to a...

Impact du régime du barrage d'Arzal sur la stratification a l'embouchure de la Vilaine : étude par modélisation numérique
Provedor de dados: 5
Autores: Le Hir, Pierre; Duchene, C.; Merel, A; De Nadaillac, G.; Merceron, Michel; Breton, Marguerite.
The rate of flow of the fresh water releases at the Arzal Dam into the Vilaine is likely to influence the haline structure of Vilaine Bay. In order to determine the rate of flow that causes a minimum downstream stratification, a vertical two-dimensional mathematical modelling of the Vilaine's estuary was undertaken. We obtain very similar stratification flows for different fresh water release scenarios, in spite of the rather different desalinisations and currents.

Autores: Abarnou, Alain; Robineau, Daniel; Michel, Pierre.
Top predators like marine mammals have been intensively used for monitoring the contamination of the marine environment, particularly in industrialized coastal areas of the Northern Atlantic Ocean. Such data concerning contamination in the Southern hemisphere are very scarce. Samples were taken in the fatty protuberance of the forehead (melon) from eleven Commerson's dolphins (Cephalorhynchus commersonii, Lacépède, 1804) caught in the coastal waters of the Kerguelen Islands (Southern Indian Ocean). They were analyzed for DDT, PCB and HCB, using capillary gaz chromatography. The levels of contamination [DDT= 1 150 ± 650, PCB = 1 150 ± 770, HCB=500±300ng/g of extracted matter (lipids)] are between ten and a hundred times Jess than those found in similar...

La production chez les crustacés. Rôle dans les écosystèmes et utilisations
Provedor de dados: 5
Autores: Khmeleva, N; Goloubev, A.
This monograph is the first to state by a systematic research the rules which control the production of the organic losses in shape of eggs and exoskeletons during the life of Crustacea. The weight and the energy content of the material thrown out are the chief criteria selected to characterize the germinal production, relative to the egg-mass, and the exuvial production, relative to the organic fraction of the exoskeleton. The determination of these parameters, at the level of the organism or of the population, takes into account the systematic position of the animals, the duration of their intermolt periods, fecundity and other indices in relation to environmental factors. The loss of matter and energy with reproduction and molting(studied for different...

Interactions entre pêcheries de lagunes, pêcheries côtières et pêche au chalut dans le golfe du Lion
Provedor de dados: 5
Autores: Farrugio, Henri; Le Corre, Gildas.
INTRODUCTION : This document is the final report concerning a study led on interactions between lagoon fisheries, coastal fisheries and trawl fishing in the Lion gulf.  If any of the three components mentioned above is able to catch species of interest (or none) to the other groups, other ones are of interest to at least two components. Furthermore, within each group, interactions between various fleet and/or trade can exist.  Interactions are more complex on account of the specific diversity of catches. If until 1984, trawler fleets were the subject of continuous studies, lagoon and coastal fleets were only considered on a one off basis... The goal of the work led by IFREMER concerning Mediterranean halieutic resources aims at obtaining basic elements...

Autores: Arbault, Suzanne; Camus, Patrick; Hersart De La Villemarque, Jacqueline; Koutsikopoulos, Constantin.
In order to analyse the recruitment process of a commercial fish, the common sole has been selected for making researches into the mecanisms which have an effect upon the distribution of the young fish stages and upon the plenty of the recruitment. In 1985, during three surveys for eggs and larvae off the estuary of the river Loire in march and april, severa! points have been studied : - physical and chemical data of the sea - distribution of eggs and larvae - vertical distribution of larvae in a little scale - some results on nutrition of larvae.

Restitution de la température de surface à échelle moyenne à l'aide du canal infra-rouge de METEOSAT-2 - Application au golfe de Gascogne

Autores: Radenac, Marie-hélène.
Jusqu'à présent, ce sont essentiellement les satellites défilants de la série TIROS-N qui ont retenu l'attention des océanographes. Ils permettent en effet, d'avoir une vue synoptique de la température de surface de l'océan à échelle relativement fine (1 km x 1 km), la répétitivité étant au mieux de 6h si les deux satellites en vol sont opérationnels. Même en compilant toutes les orbites de la semaine et en dégradant la résolution spatiale nominale du capteur, la nébulosité constitue l'obstacle majeur à l'obtention de champs de températures de surface complets. Le satellite géostationnaire METEOSAT, utilisé surtout dans la zone intertropicale, a une haute cadence d'acquisition, mais une résolution spatiale moins bonne (5 km x 5 km) que celle des défilants....

Etude de la matière organique et demande en oxygène des sédiments en baie de vilaine
Provedor de dados: 5
Autores: Merceron, Michel.
After the fish mortality through an anoxia, which occured during the summer of 1982 in the bay of Vilaine, the oxygen consumption of the sediment was investigated during spring and summer. It was found moderately important, submitted to limited evolutions along time and on different zones. A significant correlation with the organic carbon content of sediment could not be established.    The oxygen consumption of the bottom waters was approached. In the bay of Vilaine as a whole, it was found more important than the sediment consumption. It could vary in a wide range, till leading to pronounced hypoxias, especially during phytoplankton.

Influence des facteurs climatiques sur la production conchylicole du bassin de Marennes-Oléron
Provedor de dados: 5
Autores: Heral, Maurice; Prou, Jean; Deslous-paoli, Jean-marc.
The authors are comparing the recruitment, the commercialised production, the cultivated biomasses of oysters Crassostrea gigas and Crassostrea angulata  with the statistics of the meteorology (1885-1984). The temperature plays a role up on the date of spawning but partialy explains the lack of recruitment, which has less impact on the commercialised production than on the total biomass. The annual and seasonal characteristics of the precipitations and water temperatures do not show tight correlations with the variations of the production and of the biomass, for these cultivated populations in opposition with the sensitivity of the natural molluscan populations towards the climatic factors.

In this study, on one side, we have made a synthesis of the knowledge about the factors which could contribute to toxic or not dinoflagellates blooms. On the other side, we have analysed hydrological datas obtained from Vilaine bay in 1984 and 1985, by mean of two mathematical tools : 1 - The multiple linear regression; 2 - The clustering method by hierarchic classification. The first one uses an equation which aims to describe a biological phenomenon like phytoplankton blooms. The second one establishes the similarity degree between the plottings and must come to the characterization of groups of affinity stations in Vilaine bay. Among the partitions of some stations the more often found, these ones from the close extern estuary correspond to the maximum...

Due to good natural conditions and political will, marine aquaculture has developed recently around the Mediterranean sea and particularly in the non European Mediterranean countries. Both private entrepreneurship and public international cooperation have participated in this development. Most of its products are aiming at supplying European markets, where they compete not only with similar products from the European Mediterranean countries but also with other aquaculture products from the northern European countries. Advantages and constraints of aquaculture in the Mediterranean countries are analysed with regard to the project of "Euro-Mediterranean partnership" which should give birth within 25 years to a large free trade area.

Measurements of oxygen consumption in the two species Ruditapes  decussatus and Ruditapes phi/ippinarum were perfonned using hatchery-reared juveniles, grown under controlled conditions. The temperature range varied from 10 to 30°C. The linear relations between the logarithms of the dry weight and of the oxygen consumption were calculated for each species. Rates were compared in terms of standardized clam tissue weight calculated from the regression of respiration on tissue weight. Such a technique allows to make comparisons between the species by avoiding any interference from the variations in individual weight. Within this range of temperature, oxygen consumption of R. philippinarum and of R. decussatus exhibit the same variations, with a maximum at...

Autores: Bacher, Cedric; Baud, Jean-pierre; Bodoy, Alain; Deslous-paoli, Jean-marc; Dreno, Jean-paul; Heral, Maurice; Maurer, Daniele; Prou, Jean.
An assessment of the reared stocks of the Pacific oyster (Crassostrea gigas ) has been recently conducted on the major French areas of molluscs culture. The methodology proposed included both estimates of densities obtained by subsampling in the field, and aerial photographs which covered the cultivated, intertidal area. The size and the number of samples were designed to reach a precision of 10% on the final assessment in each area. The field work consisted in weighing and counting the oyster in unit areas of 0.5 m2 for the bottom culture or in trays or bags, for the off bottom technique. These results give a better knowledge of the technique evolution and of the general structures in the cultivated areas.

Evolution economique du chalutage en Méditerranée. Le cas du port de Sète (1970-1974)
Provedor de dados: 5
Autores: Meuriot, Eric; Dremiere, Pierre-yves.
The trawling activities of Sète ships grew markedly between 1971 and 1983: the number and above all the power of these trawls increased; marketed amounts went from less than 3,000 tonnes for the period 1971-1973 to more than 8,000 tonnes in 1982 and 1983. This development masks a distinct deterioration of the economic results of each category of trawl since the end of the 1970s. This deterioration results from the increase of certain operating expenses, like fuel and ENIM fees; it is also due to a tendency towards decreasing, since the mid-1970s, the intake of demersal species per unit of effort. The adaptations to the decrease of intake per unit of effort were made by increasing motor power, by a relative specialisation of 24-to-25-metre trawls in small...

Croissance et indice de condition de l'huître plate Ostrea edulis élevée en mer et en étang sur la côte méditerranéenne
Provedor de dados: 5
Autores: Paquotte, Philippe; Moriceau, Jacques.
A monitoring of the growth and condition index of the flat oyster Ostrea edulis has been conducted in the Thau Lagoon and in open sea off the Cap d'Agde. Between April and November, its growth is greater in open sea than in the lagoon. In winter, the growth doesn't stop in open sea, but one needs to get away from mussel collection in practicing seabed farming. In these conditions, the oyster's growth, throughout the year, is very close in open sea and in lagoons whereas the condition index is higher in open sea.

Etude de l'utilisation des sargasses comme floculant des eaux chargées de matières organiques.

L'exposé introductif, figurant dans notre compte-rendu du Ier Octobre I986, qui justifiait les recherches sur l'utilisation de Sargassum muticum comme adjuvant de floculation des eaux chargées de matières organiques, est à conserver : les remarques chimiques et stéréochimiques sont exactes et il nous semble inutile de les reproduire ici. Les différentes expériences que nous avons faites en utilisant les occasions que nous offraient les diverses industries agro-alimentaires de notre région, nous ont montré que l'on peut obtenir d'une façon générale des eaux claires, décolorées, désodorisées et privées d'une fraction notable de leurs bactéries. Les comptages effectués sur 3 types d'effluents différents nous ont montré qu'au moins les 3/4 des bactéries...

Caractéristiques des mortalités estivales de l'huître Crassostrea gigas dans le bassin d'Arcachon
Provedor de dados: 5
Autores: Maurer, Daniele; Comps, Michel; His, Edouard.
Summer mortalities in the Pacific oyster in the Bay of Arcachon were analysed during four years (1981 to 1984). Mortalities occur mostly among one year old oyster and affect the whole bay, with different prevalence. The phenomenon occurs at certain times during the summer spawning period and is associated with high temperatures. A thinning of the digestive tubule epithelium is observed, but there is no evidence of infectious disease. The failure to find a causative agent, pollution or pathogen, tends to strengthen a physiological disorder hypothesis, related to environmental conditions. The influence of external (temperature, available food) and internai factors (length, maturation, spawning) on this phenomenon is discussed. A comparaison is drawn with...

Les agriculteurs envisagent ou ont commencé d'aménager certains marais doux à des fins de culture. Si ces projets se réalisent, 500ha seront aménagés à terme (2 à 5 ans) dans le marais de Hiers Brouage qui en totalise 10 500. Les aménagements comportent : un isolement des ilots, une mise à plat, un assainissement par drainage et pompage de l'eau avec rejet direct ou indirect dans le milieu marin. Les administrations conscientes des risques de conflit entre agriculteurs d'une part, ostréiculteurs et associations de protection de la nature d'autre part ont souhaité qu'un suivi soit effectué sur l'Ilot des Tannes (115 ha) pris comme test. Le principe d'une "lagune" a été retenu afin d'arrêter les particules fines et provoquer une certaine stabulation des eaux...

Ultrastructural study of a parasite first reported in 1978 in Korea, in the oocytes of the Pacific oyster Crassostrea gigas then reported again in 1984 in Chungmu Bay oysters. The observed stages are typical of those of the Paramyxea Levine 1980 group. The development consists of the production of secondary cells within a stem cell; these secondary cells then producing one tertiary cell. The specific evolution of the sporogenesis leading to the production of one single tricellular spore per sporont distinguishes the studied parasite from other Paramyxea

L'impact d'une politique de limitation de l'effort de peche : Les chalutiers méditerranéens et le système des licences
Provedor de dados: 5
Autores: Meuriot, Eric; Dremiere, Pierre-yves.
Many theoretical studies since after the war have been devoted to the biological and economic aspects of exploiting halieutic resources. They often lead to, indeed focus directly on, the interest of limiting the fishing effort. In the simplest case, the one in which production automatically finds an outlet, the idea of limiting the fishing effort comes from an argument that can be presented schematically in three points:  a) halieutic resources and their renewal are limited; b) an increase in overall fishing effort cannot therefore be done while maintaining the same level of catches per unit of effort; the latter inevitably decrease. Additionally, beyond a certain level of fishing intensity, a supplementary increase of the overall fishing effort brings...

Autores: Bachere, Evelyne; Chagot, Dominique; Tige, Gilbert; Grizel, Henri.
Considering the epizootics which affect the French stock of flat oysters, Ostrea edulis (Grizel, 1985), trials to introduce an Australian oyster, Ostrea angasi, have been undertaken. The spat produced in a hatchery from breeders imported from Australia were reared in the south ofBrittany and in Normandy (Bougrier et al., 1986). Following mass mortalities (65% of individuals) a haplosporidian was observed in this species. Sporogenesis of the parasite was studied using Iight and electron microscopy.

Autores: Meuriot, Eric; Gilly, Bernard.
This econometric study is an integral part of a series of research works that IFREMER is undertaking on use planning of scallop fishing in St Brieuc Bay. It aims to provide a quantification of changes in the value of new and used boats in use in St Brieuc Bay. This study will make it possible to: (i) explain the importance of the capital invested in scallop fisheries; that will be used for analysis of the growth of this fishery from 1965 to 1985; (ii) evaluate the pace of depreciation of the capital; this latter will be integrated into a bio-economical model that analyzes various strategies of long-term exploitation of the scallop stock (see "A bio-economic model for the scallop in St Brieuc Bay", by J.M.

Thematic mapping of reefs by processing of simulated SPOT satellite data : application to the Trochus niloticus biotope on Tetembia reef (New Caledonia)
Provedor de dados: 5
Autores: Bour, W; Loubersac, Lionel; Rual, P.
Exploitation of Trochus niloticus is important for Pacific islanders. The shell yields valuable mother of pearl of wich 2.000 tons were exported from New Caledonia in 1978. Knowledge of the exploitable stock requires a good estimate of the surface area occupied by this gastropod which colonises dead coral reefs. Because trochus environments in New Caledonia are very extensive and access is difficult, synoptic methods of estimation are called for. High resolution remote sensing appears to be a particularly suitable method. Simulation of images to be obtained from the French SPOT satellite was carried out in New Caledonia in decemlber 1983. This paper deals with the method used to process the digital high resolution images that will be produced by SPOT....

In the Portuguese national economy, the role of the fishing industry is very important, although its contribution to GDP (Gross Domestic Product) is only about 1%. This sector employs 41,724 fishermen and more than 50,000 people for all activities associated with fishing. The volume of exports ensures a relatively large in-flow of foreign currency.  It must be emphasized that the fishing sector is the main supplier of raw materials for the conversion industries. Fish products supply up to 40% of the animal proteins meant for human consumption.  Portugal is the leading consumer of seafood in Europe: 35 kg per inhabitant per year. Up until 1971 and for the period of 1978-1980, the trade balance of seafood was positive with an annual average of 168 MF from...

Provedor de dados: 5
Autores: Boromthanarat, Somsak.
L'étude des moules de bouchots, Mytilus edulis L. a été réalisée pour caractériser les phénomènes biologiques et leur importance énergétique dans le bassin de Marennes-Oléron. Le suivi hydrobiologique a montré que la nourriture disponible pour les moules est plus abondante du printemps au début de l'été. Il a été possible de mettre en évidence une compétition spatiale extrêmement forte, au niveau intraspécïfique. Les moules cultivées à partir du transfert des naissains collectés sur cordes poussent plus rapidement que celles provenant d'une fixation directe du naissain sur les bouchots. La période de ponte est étalée entre février et  mai d'où l'existence de recrutement en juin. On peut proposer comme période de pêche, une saison allant de juin à novembre,...

Assessments of natural mortality of cultivated oysters (Crassostrea gigas) in the bay of Marennes-Oleron (France)
Provedor de dados: 5
Autores: Bodoy, Alain.
The natural mortality of oysters could by considered, in a man controlled ecosystem, as the result of the action of biological factors, and human factors other then the harvest of the population. Such mortalities need to be estimated in order to be used in population dynamics, as a tool for management purposes. ln Marennes-Oleron bay, different ways of estimating the natural mortality are available. Several oyster farms were monitored for assessing growth, mortality and production in rearing conditions. Furthermore, an experimental framework which includes 15 stations gave an appraisal of the same factors under controlled conditions. Finally, another estimate will be soon available by comparin9 the number of recruited oysters, and the number of oyster...

Autores: Bergeron, Jean-pierre.
Une méthode d'estimation des potentialités de production secondaire pélagique est proposée, tirant profit de l'homologie interspécifique de certains processus métaboliques élémentaires. Elle consiste à mesurer l'activité de l'aspartate transcarbamylase (A TC), enzyme contribuant à la biosynthèse de composants de base des acides nucléiques, sur des échantillons du peuplement mésozooplanctonique total. L'exécution de onze campagnes au cours des périodes printanières de trois. années consécutives, de 1978 à 1980, a permis d'appliquer cette approche à un écosystème néritique de région tempérée, situé au large de la côte nord de la Bretagne (Manche occidentale).

Autores: Grizel, Henri.
Le problème majeur allant à l'encontre du développement de l'aquaculture dans le monde, en particulier pour l'élevage des mollusques, est lié à des maladies infectieuses. Les agents responsables sont essentiellement des parasites et des microorganismes intracellulaires. Les données acquises en pathologie des mollusques sont à l'heure actuelle en majorité descriptives, mais compte tenu de l'impact économique de ces maladies, des recherches doivent être développées pour élaborer des mesures prophylactiques et thérapeutiques. Dans cette optique l'établissement de lignées cellulaires de mollusques marins constitue une priorité car, à l'instar des lignées cellulaires de vertébrés utilisées en pathologie humaine et vétérinaire, elles permettraient la production...

Deep-sea demersal fish density estimates compared from simultaneous net catches and photography
Provedor de dados: 5
Autores: Russell, Ra; Serafy, J.
The numbers of fish caught and photographed in the eastern North Atlantic (49-52°N and 10-15°W) were compared from 46 hauts, made between 1979 and 1983 using an epibenthic sledge with an ancillary camera. There were 1966 specimens captured and 258 photographed. Fish species of similar appearance were grouped to aid identification from photographs. The 20 speciesjgroups common to both gears were represented by 83.6% of the specimens captured. Although there was good correlation between the numbers, catch density was about one third of that photographed, demonstrating how much such estimates may be at variance. Larger species showed a greater discrepancy, to suggest net avoidance. A bow-wave might sweep aside less active animais. The camera also demonstrated...

Dinophysis cf. acuminata concentrations have been monitored from April to July 1985 in Vilaine Bay with 20 sampling stations and at several depths. Besides, variations in biomasses for other species have been analysed against Temperature/Salinity patterns. This study confirms 1) The importance of stratification and coastal currents in Dinophysis distribution, 2) the influence of bottom morphology on cumulative phenomenons as observed in the inner part of the Bay. In the same way, waters stratification would play an important role in species succession.

Perspectives de développement de l'élevage de la palourde japonaise Ruditapes philippinarum dans le bassin ostréicole de Marennes-Oléron
Provedor de dados: 5
Autores: Goulletquer, Philippe; Nedhif, Mohamed; Heral, Maurice.
The complete Manila clam's breeding cycle (Ruditapes philippinarum ) in oysters ponds (claires) permits  to obtain a length of 25 mm after 1 year with a density range of 200 animals/m2 . As the primary production is restricted, the breeding biomass during the second year is limited to 500 g.m2 corresponding to a density between 30 to 50 clams..m-2. For an increase of the production it is necessary to extend the cultivated area to the tida1 bottom of the Bay of Marennes-Oleron. It appears that the man tidal level between + 2 and + 2.5 15 necessary with a density range of 200.m-2 to reach, the market size nine months later. The harvest sould be done before winter time to avoid a large 1055 of the flesh which can cause high levels of mortality.

The study presents the fishing fleet replacement policy undertaken in France from 1945 to 1983. The official policy declarations held by the professional organizations and the governments on the place of the fleet replacement in the fishery economy are replaced in their context: stock abundance, conditions of access to fishing zones, demand for fish, ... The consequences of the absence of a mechanism allocating fish resources between competing fleets, wether they are foreign or national ones, are indicated. The limits of the discourses on technological « progress » and on the "rational" fishery management are discussed. Future complementary research topics are proposed in conclusion. Numerous tables and figures on French fisheries since 1945 illustrate the...

Autores: Mialhe, Eric.
The different epizooties affecting traditional or recent shellfish culture activities (hatcheries, cockle culture) brought to light some microorganisms and parasites considered as the responsible pathogenic agents. However, in a number of cases, the etiology of these massive mortalities remains unexplained (Grassostrea gigas, Ruditapes philippinarum). Some additional works, based on some electron microscopy techniques and isolation methods, are thus essential in order to precise the infectious nature of these diseases.

Croissance des larves de Crassostrea gigas et de Mytilus galloprovincialis en présence d'algues monocellulaires isolées du tractus digestif des véligères du milieu naturel
Provedor de dados: 5
Autores: His, Edouard; Robert, Rene.
The collection of Crassostrea gigas veligeres in their natural environment and the homogenate technique (HIS et al., 1985) enable the monospecific culture of nine algae which larvae feed on. Four of them could be mass-produced: Nannochloris atomus, Stichococcus bacillaris, Chlamidomonas bullosa and Tetraselmis Tetrathele. Their feeding quality has been tested using the cross-growth method, and using Crassostrea gigas and Mytilus galloprovincialis veligeres. Although regularly found in the homogenates, and thus fed on by larvae, the first three algae gave poor results. Only Tetraselmis tetrathele has good nutritional qualities for Crassostrea gigas veligeres.

The Flamanville site has been the focus of a number of hydrobiological and biological measurement cycles in the years 1976-1978 and 1983-1984. The first project studies resulted in a reference ecological assessment based on 41 missions (229 stations). The monitoring studies conducted in 1983 and 1984 consisted of 16 campaigns (32 stations). The lowering of the number of samplings between both cycles is explained by the programs coherence; the monitoring indeed focuses on a number of parameters considered as the most significant or sensitive according to the most efficient strategy.

Among the different condition indices, some of them were compared on a population of the japanese oyster, Crassostrea gigas. The follow-up of experimental racks was performed monthly during four years. The use of dry weight in condition indices gave a more precise and more reliable representation for the condition of the oysters than the fresh weight. The sensitivity of these indices, which corresponds to their ability in revealing small changes in the physiological condition, was calculated for each indice. Those exhibiting the best sensitivity were ranked as follow: dry weight on the difference between total weight and shell weight, dry weight on intervalve volume. Other indices including the ratio between dry weight and various assessments of the volume...

Provedor de dados: 5
Autores: Appery, F; Drussel, A; Gestin, Pg; Morizur, Yvon.
La présence de "glu" sur les filets maillants est constatée en Bretagne certaines saisons. Elle diminuerait les rendements de la pêche. Ce phénomène a été aussi relaté au Canada. Il semble que ces salissures soient dues au phytoplancton. Nous avons comparé le pouvoir salissant de divers types de filets rnaillants en étudiant leur colonisation par les diatomées.

La flotte de pêche française de 1945 à 1983. Politiques et réalités
Provedor de dados: 5
Autores: Meuriot, Eric.
The study presents the fishing fleet replacement policy undertaken in France from 1945 to 1983. The official policy declarations held by the professional organizations and the governments on the place of the fleet replacement in the fishery economy are replaced in their context: stock abundance, conditions of access to fishing zones, demand for fish, ... The consequences of the absence of a mechanism allocating fish resources between competing fleets, wether they are foreign or national ones, are indicated. The limits of the discourses on technological « progress » and on the "rational" fishery management are discussed. Future complementary research topics are proposed in conclusion. Numerous tables and figures on French fisheries since 1945 illustrate the...

Autores: Manaud, Francois.
La station "AQUALIVE" dans l'île de Noirmoutier doit utiliser dans un avenir proche des eaux souterraines riches en sels nutritifs à un débit de 300 m3/h. Un rejet a été constitué à l'aide du pompage expérimental reproduisant les conditions d'exploitation maximale prévues. Aucun effet certain n'a pu être observé sur l'eau de remplissage des claires (entre 1h avant et 1h après la pleine mer), ni d'effet cumulatif sur une période de 1 an.

Estimation des stocks d'huîtres cultivés : cas du bassin de Marennes-Oléron
Provedor de dados: 5
Autores: Deslous-paoli, Jean-marc.
Une estimation des stocks d'huîtres, pour quoi faire? Lorsque les stocks augmentent, la production commerciale plafonne vers 40 000 tonnes, la durée du cycle de production d'une huître de 70 g passe de 2 ans à 5 ans et plus, les mortalités courantes passant simultanément de 20 à 70 %. Le déséquilibre ainsi crée est favorable au développement des épizooties telles celles provoquées par la maladie des branchies de 1966 à 1969 et par des Iridovirus inconnus en 1970. La production d'un bassin semi-fermé comme celui de Marennes-Oléron est limitée par la capacité trophique du milieu. On aboutit rapidement à une surexploitation d'un tel système.

Un quart de siècle d'évolution de la conserverie des produits de la mer
Provedor de dados: 5
Autores: Gilly, Bernard.
The business of seafood for direct consumption in France is divided into three distinct technological procedures of stabilisation: - The drying and salting processes are the oldest. They experienced a steep decline starting at the Second World War and, paradoxically, they appear today as high-end products. - Appertisation (heat sterilising procedure developed by N. APPERT in 1801) was very widely developed along the entire French shoreline from many small companies at the end of the 19th century. The three main species processed are the sardine, mackerel and tuna. - Deep freezing is a more recent activity compared with the two preceding ones. It was developed in France starting in 1960. The growth of the market was accompanied by the creation of several...

Production d'Algues unicellulaires
Provedor de dados: 5
Autores: Blancheton, Jean-paul; Audineau, -.
Introduction: Monocellular planktonic algae are autotrophic organisms. They represent the starting point of the food chain and are the first link in primary production.  They can be found in high density in a natural environment at Springtime and Fall, times at which temperature and salinity conditions are right for their development and when adequate mineral salts availability is high. This alga production meets bivalve and Penaeid's larva nutritional needs. It also promotes the development of rotifer cultures. Selecting which species to exploit is done according to nutritional value, size, and ease of growing. Algal cell sizes vary between 2 to 100 microns. There are numerous families which are determined according to different criteria: - Nature of the...

Etude pour une gestion optimale des pêcheries démersales interactives dans le Golfe du Lion
Provedor de dados: 5
Autores: Farrugio, Henri; Le Corre, Gildas.
Un accroissement général de l'effort de pêche et en particulier de l'effort chalutier au cours de la dernière décennie a conduit la pêcherie démersale intéractive du Golfe du Lion jusqu'à une limite de productivité que les conditions d'exploitation actuelles semblent impuissantes à surpasser. Cette limite situe les captures récentes aux environs du sommet des modèles de production globaux, lesquels ne peuvent permettre que de prédire, pour les stocks halieutiques de cette région, le passage à un état de surpêche si la tendance à l'augmentation de l'effort des divers métiers se poursuivait suivant le schéma qui a prévalu jusqu'à présent. La question se pose d'évaluer les effets d'éventuelles mesures nouvelles d'aménagement de la pêcherie mais en ce sens...

Prix moyen mensuel des especes demersales en France et a Boulogne-sur-Mer : etude econometrique de la periode 1974-1983
Provedor de dados: 5
Autores: Meuriot, Eric; Gilly, Bernard.
The landed prices of the four main demersal species (whiting, saithe, haddock, cod) in France vary based on the amount landed, the average weight of the fish, imports and seasonal factors. Adapting an econometric model to the period 1974-1983 makes it possible to differentiate the four species as regards the determination of prices.  - Cod seems like the key species, around which the prices of the three other species are determined. The visible consumption of cod is the highest (around 60,000 tonnes per year, more than half of which is imported). The average landed price depends to some degree on the landed and imported amounts: rises of 10% of landed amounts and imported amounts cause a direct drop of 3% and of 1.5% respectively in the landed price.

Influence of oyster farming Crassostrea gigas on the phosphate cycle in an intertidal zone : the role of biodeposition
Provedor de dados: 5
Autores: Sornin, Jean-marc; Feuillet, Michelle; Heral, Maurice; Fardeau, Jean-claude.
Some aspects of the phosphorus cycle were studied in the estuarine bay of Marennes, Oléron, an area of intensive cultivation of Crassostrea gigas on the west coast of France. The annual cycle of dissolved phosphorus (mineral and organic) in the water column, interstitial water and at the sediment-water interface was followed, as well as the particulate phosphorus (total and assimilable) in sediments and in suspension. A comparison of the seasonal variations in these different forms of phosphorus in the suspended matters shows a deficit in "biodeposits" (sedimented faeces and pseudofaeces from Crassostrea gigas) equivalent to 20 mg.m -2.d -1 for assimilable phosphorus in July and September-October. This may be the result of consumption by the oysters, since...

Le développement croissant des cultures intensives d'algues unicellulaires marines pour l'aquaculture pose aujourd'hui le problème non seulement de la valeur nutritive de ces organismes mais également des ouvertures possibles vers un marché plus spécialisé en pharmacologie et cosmétologie. En effet, tant au niveau des propriétés étonnantes de certains produits d'excrétions (hydrates de carbone, biotoxines, antibiotiques) que des constituants de base (en particulier lipides et aminoacides) ou des complexes pigmentaires, il semble que peu d'applications semi industrielles aient dépassé l'échelle du laboratoire.

From symposiums to conferences, from reviews to evaluations, from laboratory to the field, aquaculture has not developed in apathy. Before it was even established, aquaculture challenged relationships between professionals, the scientific community, administrative authorities and political bodies. A review of documents, whatever their source, shows excessive reactions, sometimes optimistic, sometimes pessimistic. Why so much ado? How can we explain why aquaculture was accepted so heartily by professionals of the fishing industry who are generally considered to be relatively resistant to innovation? Why were stances defended so passionately by scientists, who in principle are prepared for the unexpected and trained for analysis? How can we explain why...

Etat de la motorisation de la flottille de pêche côtière en Martinique
Provedor de dados: 5
Autores: De Miras, C; Bellemare, M; Soumbo, C.
Ces premiers résultats inspirent trois principales remarques: 1 - La puissance moyenne des moteurs hors-bord varie très sensiblement de la côte atlantique A la côte caraïbe. Si la puissance moyenne en Martinique est de prés de 40 cv par moteur, les pêcheurs de la côte caraïbe utilisent une puissance moyenne unitaire de 30 cv alors que la motorisation sur la côte atlantique se situe en termes de puissance moyenne autour de 46 cv. Cette différence s'explique peut-être par le type de pêche dominant dans chacune de ces zones. En toute hypothèse, les résultats de l'activité des marins pêcheurs de la côte atlantique permettent-t-ils de couvrir et justifient-t-ils donc le surcoût engendré au niveau de "l'investissement-moteur" (de 1.3 à 1.5 fois supérieur au coat...

L'élevage larvaire intensif du loup Dicentrarchus labrax. Influence de la lumière, de la densité en proies et de la température sur l'aluminium, sur le transit digestif et sur les performances zootechniques
Provedor de dados: 5
Autores: Ronzani Cerqueira, Vinicius.
Several sea bass-rearing experiments were performed from hatching trough metamorphosis. The rearing units employed were 500 1 polyester tanks, where flow rate and temperature of seawater, light and suitable food (rotifer and artemia) were controlled. Stock density ranged between 50 and 100 larvae per liter.  Individuals held in tanks with internal black walls developed faster and had a greater survival rate than those in white tanks. This suggests that a better contrast between preys and background assists the larvae to see food organisms more clearly.  The sea bass larvae search for food is based only in vision and not trought mechanoreceptors or chemoreceptors. It was very difficult to evaluate the light intensity (50-5000 lux) influence on feeding,...

Seismic, Seabeam, magnetic and gravimetrie surveys in the southern part of the N-Fiji basin were conducted during the SEAPSO LEG III Cruise. The active spreading axis was recognized between 17°30'S and 21°S. It consists of a continuous N-S Ridge cross-cut by transverse directions oriented N25 and N45. North of 17°30'S, the spreading System is more complex due to the existence of a possible triple junction located around 15° S. The eastern part of the N-Fiji basin, west of Viti Levu is mostly characterized by alternating highs and deeps (&lt;4,000 m). This area must be regarded no more as a spreading center, but as complex boundary suffering transverse tectonics.

Méthode d'estimation de la surface de pêche d'un casier à l'aide d'une filière expérimentale
Provedor de dados: 5
Autores: Gros, Philippe; Santarelli, Leonardo.
The experimental design of the capture field area of baited whelk-pots involves, as a controlled factor, four different spacings between pots (6, 12, 24 and 36m), randomly distributed along a ground line. This spectrum of values is sufficiently broad to preclude overlap of capturing fields of sorne pots. Taking account of the patterns of the M2 tidal currents in the area studied, an ellipse was chosen as a geometrical model of the shape of the capture field. Semimajor and semiminor axes were estimated by least squares, the expected catch per pot being defined as a decreasing function of the area of overlap with adjacent capture fields. ·  Experimental fishing of Buccinum undatum L. was carried out in the Channel Isles region (Western Channel), and provided...

The bottom of the 7 rn deep water column undergoes distinct thermal events of advective origin and a strong stirring owing to a weather alteration. Heat propagation in the sand 7.0 cm below the interface in a nonstationary state is described by means of a mathematical model based on the heat conduction equation and with the assumption that the heat is conservative. This description is achieved without any adjustment of the model to the data. Since the K. value characteristic of unconsolidated clastic...

Le secteur des peches dans les pays d'Afrique

1. Enlightened indeed is the person who can claim to have precise knowledge of catches in Africa. Accuracy is in the neighbourhood of 50% or less in most cases, in statistics developed by the best teams of specialists, particularly the FAC. What is true, stock by stock, cannot be less so on the African continent as a whole. If marine fishing statistics are questionable, then what can be said of fishing throughout the continent! Thus, Zaire, with its huge hydrological network, is supposed to have 200 dugouts, less than Rwanda. We therefore earnestly beg the reader not to think that the numbers provided in this text have indisputable statistical value; they have been carefully compiled from existing sources, coming themselves very often from compilations,...

Autores: Poulet, Sa; Harris, Rp; Martin-jezequel, Veronique; Moal, Jeanne; Samain, Jean-francois.
By measuring water soluble extracts of free amino acids (DF AA) in the diets and faecal pellets of copepods using high performance liquid chromatography (HPLC), it was found that the molar composition of these molecules in the faeces produced depends on the type of food selected and reflects the hydrolysis of food proteins during digestion. On average, four amino acids (ASP, SER, GLY and LEU) together accounted for 63% of total DF AA in the faecal pellets of a variety of copepod species. The diversity of DFAA in copepod faecal pellets was higher than in sea water or in particles and phytoplankton cells ingested by copepods. These first results on DFAA in copepod faecal material indicate the importance of zooplankton faeces in the flux of dissolved nitrogen...

Croissance de différents lots de coquille Saint-Jacques Pecten maximus en culture sur le fond dans la Rade de Brest
Provedor de dados: 5
Autores: Buestel, Dominique; Gerard, Andre; Guenole, Annie.
Six batches of king scallop juveniles of different origins and obtained either by collection in their natural habitat (Saint-Brieuc, Scotland, Ireland), or by hatchery production in Brest in 1981, 1982, 1983, have been sown, at a size of 3 cm, in the roadsted of Brest between 1977 and 1983. Their growth, strongly linked to the evolution of the temperature, is well-described by a model, including a sinusoidal modulation, by Von Bertalanffy. The growth of the scallops collected in Saint-Brieuc, Scotland and Ireland, differentiates from that of the individuals from their original area and shows similarities with that of the scallops produced in Brest. Consequently, there must be an adaptation of the growth to the environmental conditions of the roadsted of...

Autores: Pichot, Yves.
The life cycle of Haplosporidium sp., Haplosporida recently observed in the flat oyster of the bassin d'Arcachon (France), and the spore characteristics of which have already been presented (Pichot et al., 1979), has been studied by electron microscopy. The first stages of sporUïation are represented by two types of plasmodia. After the stage of sporonts, sporogenesis seems to develop according ,~ to two sequences. In a first sequence a cytoplasmic syncytium is formed, followed by the condensation of cytoplasm that would lead to the individualisation of uninucleate sporoblasts and anucleate cytoplasm fragments. The spores could result from the enclosing of the sporoblasts by the cytoplasmic fragments. In a second sequence the spores differenciation happens...

Epidémiologie de Bonamia ostreae et Marteilia refringens en Bretagne en 1984 et 1985 : situation et évolution
Provedor de dados: 5
Autores: Tige, Gilbert; De Kergariou, Gabriel; Cochennec, Nathalie; Rabouin, Marie-agnès.
A systematic surveillance progam conducted since 1980 along the coasts of Britanny has followed the evolution and epidemiological state of the natural O. eulis oyster beds and seed areas in the intertidal zones and deep water. Presently, Marteilia refringens exists endemically in Brittany estuaries ; the rate and degree of infestation varies from year to year depending on the hydrological conditions and the geographical region. In no case, however, is the return of flat oyster culture envisoned. Bonamia ostreae is present not only in the estuaries but also in the deep-water rearing areas (Baie de Quiberon, Cancale, Baie de St Brieuc). The infestation increases with age, but also depends on the quantity of the stock and the culture practises. In particular,...

Autores: Maurer, Daniele; Comps, Michel.
Previous pathological studies have not permitted to implicate infectious disease in summer mortalities of oysters Crassostrea gigas, in the Arcachon bay. In 1983, these summer mortalities, occurring mostly among 1 year old oysters, have been the subject of new investigations. In order to establish the causes of mortalities, oysters of the same origin were held in two areas characterized by different prevalence of mortality for 6 months, during which measurements of physiological and biochemical condition and certain histological observations were made. The study has been completed by environmental observations. Different rates of mortality appeared between the two selected areas: 30 %in Taussat in the upper part of the bay, under a continental influence...

Depuis 1984 ,au cours de la campagne germonière des cartes de température de surface sont établies au centre de météorologie spatiale de Lannion ; elles sont transmises 2 à 6 fois par semaine par un système de radio fac-similé aux bateaux prospecteurs afin de guider la flottille vers des zones où l'hydrologie semble favorable à une concentration de poissons, notamment des fronts thermiques autour de 16° -19° C. De nombreuses observations effectuées en mer révèlent l'importance d'un second critère hydrologique dans la recherche du poisson : la limite entre des eaux vertes, richesen phytoplancton et bleues, pauvres.

Croissance et spectre de taille de trois algues en cultures non renouvelées, utilisées pour la nutrition de larves de bivalves en écloserie
Provedor de dados: 5
Autores: Robert, Rene; His, Edouard.
The different growth stages of three marine unicellular algae used in aquaculture, Isochrysis galbana, Chaetoceros calcitrans forma pumilum and tetraselmis suecica have been studied for 50 days under controlled culture conditions using a particle meter. At the same time, the size spectrum of the cells has been determined using a C 1000 scanner. The exponential growth stage is 11 days in the first two species, and 13 in the last one. Chaetoceros calcitrans forma pumilum is the smallest with an average size of 3.5 µm. Its cellular volume is constant. The average size of Isochrysis galbana is 4.5 µm. An increase of the cellular volume is observed through its stationary stage. The modal size of Tetraselmis suecica is 8 µm.  Again, an increase in the cellular...

La répartition du cadmium dans l'eau, le sédiment et la matière en suspension de la Gironde, du proche plateau cohtinental et de la baie de Marennes-Oléron a été étudiée lors de trois campagnes réalisées en conditions de débits moyens ou d'étiage de la Garonne et de la Dordogne. Des apports anormaux de cadmium particulaire par la Garonne ont été mis en évidence. Après désorption ou solubilisation, ils sont expulsés sous forme dissoute, formant un panache très net mais peu étendu en dehors duquel les concentrations en cadmium dissous sont conformes aux valeurs habituellement observées en milieu côtier. Les teneurs en cadmium dissous du bas estuaire expliquent les fortes concentrations relevées dans les huîtres de ce secteur. Le caractère récent de la...

The Analysis of ovaries confirms that spring is the period of reproduction, and shows that the age of first reproduction is two year (65 %) or one year old (35 %). Secondly, the exploitation of various statistic data shows the evolution of landings of Stripped Mullet in several harbours, and especially in les Sables d'Olonne, since 1962.  The reconstitution of the artisan trowlers effort in this harbour confirms the long decline of c.p.u.e . for Mullus surmuletus, and a rapid increase since 1981.

The coast stretching from the Nez of Jobourg and the Cape of Carteret, exposed to western marine fluxes, is characterized by a succession of rocky headlands and of bays bordered by recessing sand dunes. The intertidal zone is mostly sandy whereas the infralittoral zone consists of coarse sediments and pebbles, all this in relation to strong tidal currents. These tidal currents, avatars of the 1.2 knots drift of the Channel waters towards the North Sea, are conditioned by the filling up and emptying of the Breton-Norman Gulf where currents are among the strongest worldwide. Their anti-clockwise gyration becomes alternative and violent in tight passages (Raz Blanchard) The resulting bravage explains the good homogeneity of the water masses whose seasonal...

On March 11, 1986, the R/V Noroit, a research vessel belonging to IFREMER (Institut Francais de Recherche, pour l'Exploitation de la Mer, Paris), was on station in the northeast Atlantic Ocean (46°54′N, 11°14′W). The crew were performing a deep conductivity‐temperature‐depth (CTD) cast (water depth 4750 m) as part of a survey of abyssal circulation in that region. The towed CTD instrument unit was 120 m from the bottom when the cable ruptured, resulting in the loss of the instrument and 4788 m of cable. The cause of the cable failure was quickly diagnosed as corrosion on a rarely used part of the cable.

A numerical study of baroclinic instability at large supercriticality
Provedor de dados: 5
Autores: Klein, Patrice; Pedlosky, J.
A series of numerical integrations of the two-layer quasi-geostrophic model were carried out to investigate the nonlinear dynamics of baroclinically unstable waves at supercriticalities of O(1). The results extend and are contrasted with the results of weakly nonlinear theory valid only for small supercriticality. Particular attention is paid to that sector of parameter space in which the transition from regular to aperiodic behavior is observed for weakly nonlinear waves. It is found that aperiodic, chaotic behavior extends to parameter domains of higher dissipation as a consequence of finite amplitude effects as the supercriticality increases. Sensitive dependence on parameters remains a hallmark of the system as intervals of chaotic, periodic and steady...

Autores: Sauriau, Pierre-guy.
The main problems involved in making biomass and density estimates of benthic mol1uscs are the choice of a sampling plan, the level of systematic errors and random errors. A stratified random sampling after optimum allocation was used in the case. The benthic molluscs estimates (biomass or density) are highly variable, due to their aggregated distribution. The sampling gear used is a Smith Mc-lntyre grab which introduce a bias in the estimates. Nevertheless, the Macoma baLthica community was predominant in the bay but Cerastoderma edul.e appeared to be the dominant specie.

Hormis les facteurs anthropiques (voir références bibliographiques HIS et al .), l es facteurs nutritionnels jouent un rôle prépondérant dans le déroulement de la vie pélagique des larves de bivalves ; un déficit nutritionnel peut, à lui seul, hypothéquer les chances de captage (PERSOONE et al, 1980; HIS et ROBERT, 1985). Or les données dont nous disposons ont été presque exclusivement obtenues en milieu expérimental (voir synthèse de LUCAS, 1982); il n 'est pas certain qu'elles puissent être extrapolées au milieu naturel.

An area located between the Mont-St-Michel Bay and Jersey was monitored from 1984 to 1985. Limpet densities have been evaluated through quantitative sampling and underwater video. At the same time, some planktonic samplings have enabled the monitoring of the evolution of larval abundances. Maxima, planktonic and benthic density areas superpose each other. Moreover, the study of the populations shows that the number of young colonies is increasing, thus clearly indicating that Crepidula fornicata populating is booming in the Norman-Breton gulf.

Tendances à long terme de la production de la pêche maritime en France - 1986
Provedor de dados: 5
Autores: Meuriot, Eric.
Future prospects of landings are dependent on many political, economic and biological factors. Schematically, a large-scale increase in landings in the coming years seems very unlikely for species whose stocks are currently fully exploited. It must be emphasized that the measures meant to plan the exploitation of the stocks may often be more likely to improve the yields of the boats than to increase the overall catches. The technical difficulties associated with their implementation are the subject of studies at IFREMER. The prospects of reducing the intensity of fishing are dependent upon decisions by the professionals and the authorities; these prospects seem very unlikely in the short term but are conceivable in the mid term. The stock assessments led...

Suite de l'étude entreprise sur la texture du surimi et gel de surimi (Kamaboko) de chinchard (Trachurus trachurus)
Provedor de dados: 5
Autores: Verrez-bagnis, Veronique.
A la question : Qu'est-ce que le surimi ?, l'introduction du rapport annuel d'activité de juin 1985 "Essais préliminaires et premleres études de l'influence des paramètres technologiques sur la texture du surimi et gel de surimi de chinchard (Trachurus trachurus)" a tenté d'apporter une réponse.  Après le détail de la fabrication du surimi employée ainsi que les résultats de quelques essais préliminaires permettant de choisir les méthodes de mesures adéquates, nous avions abordé la premiere grande partie du travail - l'optimisation des conditions technologiques - et indiqué les prémices d'une étude sur la microstructure du surimi et du kamaboko.  Actuellement la première partie de l'étude est terminée et deux articles "Texture du kamaboko de chinchard...

Diversification de la production : cultures de palourdes sur estran
Provedor de dados: 5
Autores: Goulletquer, Philippe.
Les premiers essais de culture de palourdes japonaises sur estran en Charente-Maritime ont été réalisés en 1984 : le suivi de croissance de 3 populations de palourdes Ruditapes philippinarum pour 1984-1985, permet de mieux préciser l'optimum des conditions d'élevage que l'on peut envisager dans le bassin de Marennes-Oléron. Du fait du ralentissement de croissance en période estivale, entraînant un retard au niveau de la reproduction et un état physiologique relativement affaibli à l'entrée de l'hiver, qui conditionne les mortalités hivernales, il apparaît d'ores et déjà aléatoire d'entreprendre des élevages à des coefficients de marée inférieurs à 50. En effet, comme pour les populations d'huîtres (Héral et al., 1983), un amaigrissement hivernal prolongé...

Le déficit commercial des produits de la mer quels enjeux ?
Provedor de dados: 5
Autores: Weber, Jacques.
The external trade deficit of seafood is a subject of general concern, for the administration as it is for the profession and for research. From IFREMER's inception, its president, Mr SILLARD, made this problem one of the major guiding factors of the Institute by asking, as early as 1984, research teams to provide him with a complete and detailed view of the evaluation of seafood in France. The objective assigned to this task was twofold: assess France's room for manoeuvre and establish a research policy that must contribute to the improvement of this room for manoeuvre. The external trade deficit of sea products is a significant, long-term, structural problem to which it is conceivable to apply partial solutions. It is a national and therefore...

On the contrary to the U. S. where they represent but 4.6% of the total marine production , mollusc, principally bivalves, can no longer be considered as a marginal production. In France, 100 000 ton of oysters, 98% of which is represented by Crassostrea gigas (Héral &amp; al., 1985) and 85 000 ton of mussels (Mytilus edulis, Mytilus edulis galloprovincialis) (Dardignac, 1985) are produced yeraly. Elsewhere, new rearings are being developed, such as pectinidae and Ruditapes philippinarum, on the Atlantic and Mediterranean coasts.

Amenagement des peches dans les eaux communautaires: potentiel et limites des systemes de licences

Autores: Meuriot, Eric; Maucorps, A.
Fishing regulations in waters under the responsibility of the EEC mainly concern three techniques of site development:  - catch quotas by species and by area (TAC, a word adapted from the English Total Allowable Catch); - the definition – of the technical characteristics of the fishing devices used (meshing, type of trawl,...); - setting a minimum commercial size for each species.  The regulations of meshing and other constraints relating to the technical characteristics of the fishing devices aim to modify the composition of the catches by age class.  The TACs are a technique for controlling the level of exploitation of the stocks. Controlling the fishing effort that they generate is carried out indirectly in the short or mid term.  For many years now,...

Comparative studies in Chelicerata IV. Apatellata, Arachnida, Scorpionida, Xiphosura
Provedor de dados: 16
Autores: Hammen, L. van der.
A comparative study is made of four chelicerate classes: Apatellata (Solifugae and Pseudoscorpionida), Arachnida s. str. (both groups of Uropygi, i.e. Holopeltida and Schizomida, Amblypygi and Araneida), Scorpionida and Xiphosura. Methods, principles and terminology, adopted in this paper, correspond with those of parts I -111 of the present series of comparative studies in Chelicerata. Special attention is paid to segmentation of the body, respiratory organs, orifices of coxal glands, mouthparts, and appendages. The evolution of these structures is studied, and the relationships of the chelicerate classes and subclasses are reinvestigated and discussed.

Provedor de dados: 16
Autores: Mueller, Gregory M.; Vellinga, Else C.
Laccaria amethystea, not L. amethystina nor L. calospora, is shown to be the correct name for the amethyst colored Laccaria. A neotype for L. amethystea is proposed and a complete list of its synonyms is given. Data which support placing L. ohiensis and L. tetraspora in synonymy with L. laccata are discussed and three varieties within L. laccata are recognized. These varieties are L. laccata var. laccata, L. laccata var. moelleri, and L. laccata var. pallidifolia. Based on these data, a synonymy list and description of each variety is presented. Laccaria laccata var. pallidifolia is shown to be the most common and abundant variety. The correct name for L. striatula sensu Sing. non Peck is L. pumila and for L. ohiensis sensu Sing, non Montagne is L. fraterna.

Notes on Hygrophoraceae — VII. On the taxonomy and nomenclature of some species of Hygrophorus
Provedor de dados: 16
Autores: Arnolds, Eef.
Taxonomy and nomenclature of some West European species of Hygrophorus are discussed. The current use of Hygrophorus cossus (Sow.) Fr. as correct name of H. chrysaspis Métrod is rejected. Instead the name H. discoxanthus (Fr.) Rea is reintroduced. Hygrophorus barbatulus Becker is synonymized with H. penarius Fr. Hygrophorus melizeus (Fr.: Fr.) Fr. is considered as an earlier name of H. karstenii Sacc. &amp; Cub. and a neotype from Sweden is indicated and briefly described. Hygrophorus leucophaeus (Scop.) Fr. is rejected as a nomen dubium, the valid name of this species in its current concept being H. unicolor Gröger. Hygrophorus quercetorum P.D. Orton is reduced to a variety of H. eburneus.

Observations on a living specimen of the giant hydroid Branchiocerianthus imperator
Provedor de dados: 16
Autores: Omori, M.; Vervoort, W.
The largest known solitary hydroid, Branchiocerianthus imperator (Allman, 1885), was first collected on June 17, 1875, with a trawl-net, off Boso Peninsula on the Pacific coast of Japan, during the Challenger Expedition; it was described as Monocaulus imperator Allman, 1885. On June 21, 1985, 110 years after its discovery, a living specimen was observed for the first time, using the submersible "Shinkai 2000". The species is a suspension feeder and a carnivore: a symbiotic shrimp was found associated with it. Recently the species has been recognized from photographs taken in deep water of the N.E. Atlantic by the French IFREMER/CEA Expedition, apparently the first Atlantic record.

Mediterranean Octocorallia: description of Clavularia carpediem n. sp. and synonymy of Clavularia crassa and C. ochracea on etho-ecological grounds
Provedor de dados: 16
Autores: Weinberg, Steven.
A new stoloniferan octocoral from the Mediterranean (Morocco) is described under the name Clavularia carpediem and critically compared with C. marioni Von Koch, 1891 and C. arctica (Sars, 1861). A thorough redescription of the latter species is given. The recent discovery that the common rock-dwelling colonies belonging to a species hitherto referred to as C. ochracea Von Koch, 1878 incubate their eggs on the outside of the polyps, a rather unusual fact among Octocorallia, leads to the synonymy of this species with C. crassa (Milne Edwards, 1848), so far considered a rare species living exclusively as an epibiont on the Mediterranean sea-grass Posidonia oceanica.

The South American cichlid species Crenicichla saxatilis (Linnaeus, 1758) is redescribed and figured. The variability of colour pattern, and raeristic and morphometric characters are recorded, based on examination of hundreds of specimens from Surinam, including the lectotype. The morphometric characters are tested on validity and discussed. The distribution of C. saxatilis in Surinam is delimited, and the type-locality is restricted to Carolina ( = Malasie) Creek, Suriname River system. Remarks on the status of Crenicichla saxatilis albopunctata Pellegrin, 1904, and of Crenicichla alta Eigenmann, 1912, are included.

A revision of the Genus Scincella (Reptilia: Sauria: Scincidae) of asia, with some notes on its evolution
Provedor de dados: 16
Autores: Ouboter, P.E.
Of the genus Scincella Mittleman, 1950 (sensu Greer, 1974) 337 specimens from Asia were examined for 74 characters, which were treated in a numerical-taxonomic way. The dendrogram resulting from this analysis was not stringently adhered to. Because of the wide variation in certain numerical scale characters within one taxon or even within one population, these characters (used by many authors as key characters to separate taxa) are not regarded as very important. For sympatric and parapatric species other characters, including relative size of head, body and limbs, are regarded as very important, because these characters are influenced by the way of life (niche separation). For the separation of allopatric species scale-numbers, but many other characters...

De Oekologie van Nederlandse Waterkevers (een literatuuronderzoek)
Provedor de dados: 16
Autores: Brinkkemper, Otto.
In this review an attempt is made to find correlations between the occurence of (groups of) waterbeetles and their ecological demands, based on data from literature. To do so, several similarity-indices were calculated by means of a computer. The assumption was made, that species with comparable demands will often be found together in sampling-sites. By means of a clustering-program dendrograms are made, in which groups and sampling-sites with a high mutual similarity are grouped. Ideally, these groups shall contain species with similar ecolocical demands or ecologically comparable sites. In this study, the qualitative similarity-index of Jaccard resulted in better interpretable dendrograms than the Euclidian distance, a quantitative index, did. In the...

Using light microscopy, a method has been developed for the identification of feathers and feather fragments collected after collisions between birds and aircraft. Characters of the downy barbules of feathers are described for 22 orders of birds. The use of a key in combination with the macroscopic method of comparing feathers with bird skins in a museum collection results in identification to order or family level in 97% of the analysed bird strikes. Application of the method to other fields of biological research including taxonomy is discussed.

Description of Cynotelopus notabilis n.g., n.sp. (Sphaerotheriida). The genus belongs to the tribe Cyliosomatini of the family Sphaerotheriidae, and appears to be related most closely to the eastern Australian genus Epicyliosoma Silvestri ( = Cyliosoma auct.). This constitutes the first record of a pill-millipede from Western Australia. Spirobolellus philiporum n.sp. (Spirobolida) is described from Philip Island (near Norfolk Island, Pacific Ocean). This probably endemic spirobolellid is the first millipede recorded from the island. Atopogonus bucculentus n.sp.

Insecticidal properties of the neem tree (Azadirachta indica): it’s for the birds!

New Scientist (6 June 1985, p. 10) reported that Azadirachta indica (Meliaceae), the Indian neem tree, would be a ’new’ wonder plant. Its medical properties have been known for ages to local people and western botanists (e.g. Garcia de Orta, 1567). In India about 14 million trees, typically planted along roadsides, produce fruit, wood and leaves, all of which have special uses to the villagers. Parts of the tree have strong insecticidal and anti-nematode properties and have been used traditionally in India and Indonesia. Infusions or tinctures prepared from the bark are believed to be beneficial against malaria, although experiments have not yet confirmed this. Although the leaves (as the other parts of the plant) are very bitter, they have been used in...

Entoloma juniperinum: a new species from Juniperus heaths in North-Western Europe
Provedor de dados: 16
Autores: Barkman, J.J.; Noordeloos, M.E.
During a long-term mycological investigation of Juniperus communities in north-western Europe by the first author, a small Entoloma species was found, which did not seem to fit with one of the known species of Entoloma with a brownish pileus and bluish stipe, because of the small, almost isodiametrical spores and clamped basidia. The only species which seemed to be related was Entoloma lampropus in the sense of Kühner &amp; Romagnesi (1953). That species however, turned out to be clearly different in a number of characters such as size and shape of spores and structure and pigmentation of the pileipellis (see Noordeloos, 1982). Therefore the collections of this apparently new species were examined by the second author in the course of a critical revision...

Taxonomic status and nomenclature of several European taxa of Hygrocybe are discussed. It is argued why some new combinations, made in a previous paper (Arnolds, 1985b) were proposed. Three new taxa are described to replace incorrect names: Hygrocybe cystidiata Arnolds (= H. obrussea sensu Kühner), H. lepida Arnolds (= H. cantharellus sensu auct.) and H. conica var. conicopalustris (R. Haller ex) Arnolds (= H. conicopalustris R. Haller, nom. inval.). Three new combinations are proposed: Hygrocybe miniata (Fr.: Fr.) Kumm. var. mollis (B. &amp; Br.) Arnolds, H. virginea (Wulf.: Fr.) Orton &amp; Watl. var. fuscescens (Bres.) Arnolds and H. persistens (Britz.) Sing. var. cuspidata (Peck) Arnolds. The following names are reduced to synonyms of older or...

Siberian Syrphidae
Provedor de dados: 16
Autores: Violovitsh, N.A.
The Syrphidae constitute one of the most representative families in the sub-order of Diptera Brachycera, the fauna of Siberia numbering about 600-700 species (the whole of the U.S.S.R. numbering about 1100). They occur practically everywhere and are of considerable economic importance, chiefly as pollinators of Angiosperm plants. Moreover the larvae of many species are predators of aphids and often reduce their numbers considerably, which has a noticeable useful effect. Only a small number of species are plant pests: especially bulb plants (onion, tulip, hyacinth, etc.) are damaged through boring in the bulbs. The usefulness of the Syrphidae as a whole, however, greatly exceeds the nocivity of these few harmful species. Recently, as a result of the growing...

Oecologie en verspreiding van Vaccinium x intermedium Ruthe in Nederland

Autores: Arts, G.H.P.; Dederen, L.H.T.; Weeda, E.J.
Vaccinium X intermedium Ruthe is a natural hybrid of V. myrtillus and V. vitis-idaea. The hybrid shows conspicuous intermediacy between both parent species. In Great Britain the hybrid could only be resynthesized when V. myrtillus was the female parent. The plant shows partial sterility and a greater capacity to reproduce vegetatively than both parent species. The existence of two forms of V. X intermedium is discussed. Most probably nm. multiflorum is the backcross of nm. intermedium and V. vitis-idaea. Of all localities in the Netherlands the Imbosch (National Park Veluwezoom) has been thoroughly investigated. In the Imbosch-area the percentage of localities situated in heath communities and open pine forests (84%) exceeds the percentage in the whole...

The reasons for this new chapter have been given in the Editorial. No undescribed taxa will be accepted, these should be published elsewhere, as the Flora Malesiana Bulletin is not to be regarded as an effective publication in the nomenclatural sense. The list, moreover, would be too long and the work to extract them from the vast literature too burdensome. Such information will be mentioned, as before, in the chapter on Progress or in the Bibliography.

Terrorist tactics in taxonomy

Autores: Veldkamp, J.F.
Under the catching title given above G.B. MONTEITH, Queensland Museum, has written an editorial in the Austr. Entom. Soc. News Bull. 21 (1985) 66—69, which has been copied in the Austr. Syst. Bot. Soc. Newsletter 44 (1985) with a comment by A. KANIS (CANB). Although it mainly concerns Australian herpetologists, many readers of the Flora Malesiana Bulletin will not have these journals available, so a short summary of its contents seemed to be in place, to give the situation a broader audience. Two Australians, who we will not honour to name, nor call scientists, have published two large, privately-owned, unrefereed papers in 1984 and 1985, purporting to revise the entire Australian herpetological fauna. They have added no less than 470 new or revived...

Autores: Gotto, R.V.
A new genus and species of parasitic copepod, Megallecto thirioti, has been found in a horizontal plankton haul at 100 m depth in the eastern north Atlantic. Its host is very probably a pteropod mollusc belonging to the thecosome group. This copepod would appear to be related to Micrallecto uncinata Stock, 1971 and Nannallecto fusii Stock, 1973, but differs from both in its much larger size and in several important structural features.

It is proposed to use the line transect method or long and narrow rectangular plots, both at right angles to the vegetation gradient.

An enigmatic suppressed book by Lotsy on the Monocotyledons of Java

Among the numerous works of J.P. Lotsy Mrs. M.J. van Steenis-Kruseman (Fl. Mai. I, 1, 1950, 331a) cited ’Die Monocotylenflora von Java (1904)’ a citation derived from the biography of Lotsy by WA Goddijn (Genetica 13, 1931, xiv). It appears that after his stay in Java (1895—1900) Lotsy had decided to frame a work on the flowering plants of Java within the scheme ’Flore de Buitenzorg’ initiated by Melchior Treub. He started this probably in Leiden in 1900 still working on it until 1905. It would represent volume 7 of Treub’s work.

The nomenclature of Russula species and the Sydney rules

Autores: Singer, R.; Machol, R.
A recent paper by Th. W. Kuyper &amp; M. van Vuure shows general agreement with an earlier paper by Singer &amp; Machol on many nomenclatural problems and on the number of Russula species affected by the new starting point rules. A few minor disagreements with regard to contradiction between Arts. 13.1 and 63 are mentioned, and those regarding R. delica, R. nitida and R. atropurpurea are explained. We conclude (contrary to Kuyper &amp; van Vuure’s conclusions) that their statements confirm that Art. 13.1 as it now stands is detrimental to stability in nomenclature of Basidiomycetes, and unsettling as well as burdensome to the working taxonomist, and should be changed according to Proposal 42 now before the Nomenclature Committee.

He had been there for some abdominal complaints and a slight fever: an abscess on the appendix, perhaps. It was therefore a shock to all of us when he so suddenly and unexpectedly died. A small ceremony was held at the Rijksherbarium on 26 May. In line with his scientific and agnostic attitude he has bequeathed his body to Science.

The vegetation of the pale green patches in the mountain forest on the North side of Mt. Pangerango (West Java)

Everybody visiting the Cibodas Mountain Garden must have observed that on the North side of Mt.

Sensonator valentiensis n. g., n. sp. (Amphipoda) from different biotopes in southern Valencia

A new species, Sensonator valentiensis, the only representative of a new subterranean amphipod genus, was discovered in a rather small area in the S.E. part of the province of Valencia. A few specimens have been found in wells, a hyporheic habitat, and a phreatic cave lake. In general, Sensonator has a rather primitive morphology with remarkable features such as presence of calceoli on the antennae in both sexes, reductions in the mouthparts, and a natatory third uropod. The new genus is very distinct from other stygobiont amphipods, and it cannot even be classified in one of the existing families of Gammaridea, but with some reserve it is placed close to the Gammaroidea and Pardaliscoidea. S. valentiensis was not attracted by baits, but has been seen...

Vestiging van bijzondere plantesoorten in het infiltratiegebied van de Amsterdamse Waterleidingduinen

The ‘Amsterdamse Waterleidingduinen’ is a dune area near Haarlem in the calcareous Dune district. Since 1851 it is the water catchment area of Amsterdam. Due to the lowering of the groundwater level the moist dune slacks have disappeared gradually. Since 1957 infiltration of water from the river Rhine takes place for the water supply of Amsterdam. This water, rich in nutrients, causes among others a ruderal vegetation of high forbs and poor in species instead of the former species-rich dune slack vegetation. Since about 1970 locally a divergent vegetation is developing.

Preliminary note on the pump samples of the Amsterdam Mid North Atlantic Plankton Expedition 1980 (Project 101A)
Provedor de dados: 16
Autores: Spoel, S. van der; Goessens, F.
Pump samples filtered from the sea-water tap have been used to determine microplankton volumes, species diversity and faunal composition in the different water masses sampled by the Amsterdam Mid North Atlantic Plankton Expedition between 55°N 30°W and 24°N 30°W in the period 9 April – 6 May 1980. The presence of a plankton bloom south of 40°N could be demonstrated. Six faunal assemblages are distinguished, viz.: Subarctic, Cold Temperate, Warm Temperate, N. Sargasso Sea, S. Sargasso Sea and a more Tropical assemblage. Some traces of upwelling near 55°, 48° 38° and 30°N could be demonstrated by the presence of benthic Foraminifera in these shallow samples. A list of samples is provided.

The number of stamens in the family Aristolochiaceae range between 6 and 46. This range has been speculated to be a reduction series; nevertheless, not even a single taxon within the family is so far known to possess staminodial appendages. Floral anatomical studies of the three morphotypes of the species Thottea siliquosa (Lamk.) Ding Hou referred by three taxonomically synonymous nomenclatural species, viz. Apama siliquosa Lamk., Bragantia dalzellii Hook. f. and B. wallichii W. &amp; A., brought to light the existence of staminodes.

The instability of the tropical ecosystem in New Guinea
Provedor de dados: 16
Autores: Johns, R.J.
The tropical ecosystem has been considered by many authorities as a stable vegetation type that, in some areas, has ‘existed uninterruptedly since a very remote geological time’ (Richards, 1952). The long term stability of rainforest ecosystems was first questioned when studies showed that there was a marked contraction of rainforest areas in the tropics during Pleistocene times (Flenley, 1979). Within New Guinea two major effects are reported: altitudinal fluctuation of the major vegetation zones at higher altitudes, as described by Flenley (1972), Hope (1976), Powell (1970), and Walker (1970); and a decrease in precipitation. As a result of the lower rainfall during the Pleistocene era (17,000—14,000 yrs BP) extensive areas of New Guinea were...

Agaricus geesterani, spec. nov. A very remarkable agaric discovered in the Netherlands
Provedor de dados: 16
Autores: Bas, C.; Heinemann, P.
For several years now a very striking agaric is known to occur in the Netherlands that baffles every mycologist who has the luck to see it. As one of us (P.H.) never had this luck, the present study is based on thorough examinations of the material by the other author, while for the rather precarious taxonomic decisions both authors are to be held responsible. At first sight the present species resembles a large Agaricus bitorquis, but on closer examination the differences are obvious and manifold. There is however no doubt about the fact that it belongs to the Agaricaceae. It combines microscopical characters of the (sub)tropical genus Micropsalliota with a type of basidiocarp like that of the heaviest species of Agaricus. We think, however, that it...

Manual for collecting Agarics (&amp; Boleti)

Autores: Jansen, Annelies E.
This brief guide has been prepared during a stay in Malaysia as an aid to local collectors and turned out to fulfil a need. A wider public may find it of use as well. The writer gratefully acknowledges improvements by Dr. C. Bas, Leiden. (Ed.) As agarics and boleti belong to the most common, but also to the most difficult fungi to collect and preserve, this guide is written particularly for this group of macromycetes. Obviously many recommendations and indications will apply to other fungi with fleshy fruit-bodies as well. Macromycetes with nonfleshy fruit-bodies can be treated in the same way, but for identification afterwards extensive descriptive notes are usually not necessary.

Autores: Boer, A.J. de.
The name conviva group is proposed for a group of five species of the genus Baeturia Stål, 1866, from the Moluccas and the Vogelkop peninsula (= Tjendrawasih), New Guinea. The monophyletic origin of this group is made plausible. Three of the species (B. conviva, B. quadrifida and B. schulzi) are redescribed, while two (B. laureli and B. hardyi) are described as new. For B. schulzi a lectotype is designated. B. hirsuta Blöte, 1960 is brought into the synonymy of B. quadrifida Walker, 1868. A key to the males and a map of the distributions are presented. Biogeographical data of this group suggest an Outer Melanesian Arc distribution.

Territorial behaviour in Crested Newt Triturus cristatus and Marbled Newt T. Marmoratus (Amphibia, Urodela)
Provedor de dados: 16
Autores: Zuiderwijk, Annie; Sparreboom, Max.
Mating and premating behaviour of the Crested Newt Triturus cristatus and the Marbled Newt T. marmoratus were studied in both the natural habitat and aquaria. Attention is focussed on male interactions. During the breeding period, males occupy open spots on the bottom of a pond defending these against other males. Such defense consists of a series of display movements, usually chasing the visiting male away. The male-male display has been interpreted as territorial behaviour. Territories are usually occupied for a period of one evening or less. Male-male encounters take place more frequently than male-female encounters. The observed behaviour has characteristics of lek-breeding.

The Status and Distribution of the Spoonbill Platalea leucorodia. A review of its past and present status, migration routes, and wintering areas
Provedor de dados: 16
Autores: Wetten, J.C.J. van.
The spoonbill Platalea leucorodia is a colonial waterbird with a wide distribution in the Palearctic. The colonies are situated close to areas with shallow water near the edges of lakes, rivers, pools, lagunes, mangroves, and deltas where some quiet undisturbed places with reedbeds or low trees occur. As the spoonbills are very shy, due to prosecution by mankind, it is important that during the courtship and nestbuilding period the colony site occurs is not disturbed. The nests are build at a distance of some 50-100 cm from each other and are made of branches and reeds. When breeding in reedbeds the nests are situated close to the waterfront and young spoonbills are, after becoming able to walk, often found strolling in the water.

Fossil Odobenidae in some Dutch collections (Mammalia, Carnivora)
Provedor de dados: 16
Autores: Bosscha Erdbrink, D.P.; Bree, P.J.H. van.
Eight cranial and five postcranial fossil specimens are described and identified as remains of Odobenidae. Two of these (one, from Rhenen, certainly, and the other tentatively) are ascribed to the fossil, Early Pleistocene Odobenus huxleyi (Lankester, 1865), the others to the recent form, O. rosmarus (L.), while it appears possible to ascribe two of these even to the Adantic subspecies rosmarus. Some critical remarks are made regarding the systematic value of the genera Trichecodon and Alachtherium and the species antverpiensis (Rutten, 1907). The latter may eventually prove to be identical with huxleyi.

Over de eerste vondsten van twee Pennella-soorten (Crustacea: Copepoda) en van Conchoderma virgatum (Spengler) (Crustacea: Cirripedia) in Nederland
Provedor de dados: 16
Autores: Huwae, P.H.M.
On 30 November 1941 a sunfish Mola mola (L.) was found on the beach near Schoorl (Province of Noord-Holland). The fish was parasitized by a specimen of Pennella filosa (L.) (Crustacea, Copepoda) on which a specimen of Conchoderma virgatum (Crustacea: Cirripedia) had attached itself. This is the first and so far only record of these two crustaceans for The Netherlands. Another species of the genus Pennella, P. crassicornis Steenstrup &amp; Lütken, had been previously recorded from the Dutch coast (on Balaenoptera acutorostrata Lacépède); this record is also discussed here.

Bij het verschijnen van soortenlijsten als voorliggende ‘Naamlijst van de flora van Nederland en België’ is het gebruikelijk dat over de totstandkoming ervan bericht wordt. Op deze regel zal hier geen uitzondering worden gemaakt, omdat het de lezer wellicht zal boeien om te vernemen waarom nu reeds, zo kort na het verschijnen van de ‘Naamlijst van de Nederlandse plantesoorten’¹, het al weer nodig bleek om een nieuwe lijst uit te geven. We zijn er ons van bewust dat de recentelijk reeds aangeslagen stabiliteit van de Nederlandse namen, die tot voor kort groter was dan die van de wetenschappelijke namen, hierbij opnieuw in het gedrang komt. Omwille van de hieronder geschetste redenen leek het ons nochtans zinvol, en beter vroeg dan laat, nieuwe hervormingen...

Neogene Mollusca from the Vogelkop (Bird's Head Peninsula), West Irian, New Guinea
Provedor de dados: 16
Autores: Beets, C.
During a reconnaissance of the Tertiary formations in the western Vogelkop in 1929/1930 for the Bataafsche Petroleum Maatschappij, The Hague, the geologists J.P. Roothaan and J.B. Woolley collected a number of fossil molluscs in the outcrop area of the Klasaman Formation, later to be dated as 'Late Miocene and Plio-Pleistocene' on the basis of foraminiferal studies carried out in the course of a 25 years' search for oil (1935-1960), by the Nederlandsche Nieuw Guinea Petroleum Maatschappij. In 1930, Dr K. Martin made a preliminary examination of the fossils, which in recent years were restudied by the present writer, the number of species identified thereby being raised from 16 to 35. Unfortunately, an attempt to determine the ages of at least the two...

Veranderingen in de epifytische korstmos-flora van het Staelduinse bos in de periode 1949-1984

Autores: Bakker, Arjan de.
In 1949, 1973 and 1984 the wood of Staelduinen near Hook of Holland was surveyed for epiphytic lichens. After a sharp decline in the quality of the epiphytic flora from 1949 till 1973, a slight improvement was noticed in 1984, corresponding with a decrease of the concentration of sulphur dioxide in the air (fig. 1). It will probably take many more years for the epiphytic lichen flora to regain the 1949-quality-level.

An enumeration of bird specimens from Bangka present in museum-collections, has resulted in a faunal list of 172 species (176 forms). A discussion is given of the zoogeography of the island, the avifauna of which is mainly Sumatran in its affinities, but with a distinct Bornean influence. In contradistinction to a previously-published opinion (de Schauensee, 1958), there is no recognizable Javanese element in the avifauna.

Een tropisch drijfzaad, Pangium edule Reinwardt (Flacourtiaceae), van het Nederlandse strand
Provedor de dados: 16
Autores: Cadée, G.C.
A seed in the collection of the Rijksherbarium from the Dutch coast (1971) appears to belong to Pangium edule. Although able to drift for a long time, it is improbable that this Malaysian seed reached the Dutch coast all the way by sea currents. Transport by man to NW. Europe is the most probable explanation for its occurrence on the Dutch coast. Import of tropical seeds and fruits particularly for decoration has increased. As a result it becomes more difficult to prove longdistance transport by sea for tropical drift-seeds found on the Dutch coast.

Review of taxonomic characters in African Buzzards (genus Buteo)
Provedor de dados: 16
Autores: James, Anthony H.
This paper reviews various external characters in Old World buzzards (genus Buteo) in an attempt to clarify the taxonomic status of the small African Buteos. The results of shared characters indicate that B. trizonatus and B. brachypterus are closely similar and show resemblence to the japonicus-group of B. buteo which implies relict populations in southern Africa and Madagascar. Buteo oreophilus of eastern Africa is correlated in structure and some random aspects of plumage with B. auguralis and thus may be considered monophyletically related. On the great plumage disparaties and few character similarities B. oreophilus and trizonatus possibly should not be considered conspecific, pending further studies on apparent intermediates occurring in Malawi.

In this monograph the three genera, Physalacria, Hormitaria, and Pseudotyphula, and the altogether 31 species of the mainly tropical to subtropical Physalacriaceae known in the world are described, illustrated, discussed, and keyed out. Three new species are introduced. This study is based on herbarium material which includes all available types. The classification adapted is that of Corner. No sides are taken in the controversy between Corner who places the family in the Aphyllophorales and Singer who places it in his Agaricales. But the point is stressed that several species present marasmioid characters.

Autores: Stock, Jan H.; Rondé-Broekhuizen, Brigitte L.M.
A group of exclusively subterranean Amphipoda, the Metacrangonyx group, is distributed mainly in northwestern Africa, with peripheral isolates on the Balearic Islands and in the Sinai desert. The discovery of a new species of this group, belonging to Pygocrangonyx, a genus known from N.W. Morocco only, on Fuerteventura (one of the eastern Canary Islands) is of great biogeographic interest since it supports the theory that this island is of continental rather than oceanic origin.

Scapania undulata was recorded on the bank of the Hegebeek in the southeasternmost part of Twente, near the German border. It was first collected there in 1977. Curiously enough, this hepatic was discovered in the Netherlands only as late as 1956, although it is not likely to be a recent immigrant. Sofar records had only been published referring to rivulets on the Veluwe (prov. of Gelderland) and near Hilvarenbeek (S. of Tilburg, prov. of Noord-Brabant). It thrives on woody or stony substrata about the spring water level. Along the Hegebeek, it was found exclusively on Alnus glutinosa-roots uncovered by the stream.

Ecology of the Long-tailed Skua, Stercorarius longicaudus, at Scoresby Sund, East Greenland. Part four: Breeding success and growth of young
Provedor de dados: 16
Autores: Korte, J. de.
Breeding success and growth of young of Long-tailed Skuas were investigated in Northeast Greenland at Kap Stewart in 1973 and 1974, at Ugleelv and Kærelv in 1975, and at Kærelv in 1979. Territorial pair density was positively correlated with the percentage snow-free area in June. In 1973, estimated mean egg production per territorial pair was 1.4, but no young hatched. Egg loss was due to predation by Arctic Foxes, Alopex lagopus. In 1974 no eggs were produced due to scarcity of food on the tundra. In 1975 and 1979, estimated mean egg production per territorial pair was 1.2 and 1.9, respectively, and young did hatch, but none of them fledged. In both these years two-thirds of overall egg and chick mortality was caused by Arctic Foxes. Survival time of...

The food ecology of the Spoonbill. Platalea leucorodia
Provedor de dados: 16
Autores: Wetten, J.C.J. van; Wintermans, G.J.M.
In the past the spoonbill Platalea leucorodia used to breed in the Netherlands in far larger numbers than it does today. Recently the cause of the drastic fall in numbers was pollution of the environment with chlorinated hydrocarbons (Rooth and Jonkers,1972) during the years 1963 to 1970 (Fig. 1) Since 1970 the population has been recovering and numbers are increasing. Especially on the Waddensea-islands the increase in numbers of breeding pairs is striking. At several places new colonies have been established. At the moment the spoonbill are breeding in seven colonies all situated in the north-western part of the Netherlands (Fig. 2). Nevertheless, the total number is still much lower than at the turn of the century, or even shortly after the second world...

It is one of the results of the Polypodiaceae-project that is being carried out under the supervision of Prof. Dr. Hennipman (State University, Utrecht). With this treatment of Pyrrosia, the group of the Platycerioid ferns (sometimes regarded as a subfamily) will be completed. The total number of genera in this group is reduced to two: Platycerium and Pyrrosia. Other publications dealing with this group are Hennipman &amp; Roos (1982), dealing with Platycerium; and Ravensberg &amp; Hennipman (1986), dealing with the former genera Drymoglossum and Saxiglossum, now in Pyrrosia. Together with Hennipman &amp; Ravensberg’s account this forms the first complete account...

Autores: Glas, G.H.
The present distribution of bats (Chiroptera) in The Netherlands is documented and discussed. For each species a map is given illustrating the distribution before and after 1970. Where available, data are presented on migration, population trends, nursing colonies, roosts and hibernation sites, reproduction, and other data such as foraging behaviour, etc. Each chapter dealing with a particular species is followed by an English summary, to which the reader is referred for further information. Most species have decreased since 1970.

The recent species of Megabalanus (Cirripedia: Balanomorpha) with special emphasis on Balanus Tintinnabulum (Linnaeus) Sensu Lato
Provedor de dados: 16
Autores: Henry, D.P.; Mclaughlin, P.A.
Since Darwin's (1854) description of 11 varieties of Megabalanus tintinnabulum (Linnaeus) [as Balanus tintinnabulum], 26 Recent taxa have been assigned to the genus. In this review, two taxa confounded by Darwin are reestablished [i.e., M. crispatus (Schroter) and M. dorbignii (Chenu)]. M. antillensis (Pilsbry) and M. intermedius (Darwin) are placed in synonymy with M. tintinnabulum sensu stricto. M. galapaganus (Pilsbry) is synonymized with M. peninsularis (Pilsbry) and M. xishaensis Xianqui &amp; Liu is considered a synonym of M. occator. Diagnoses and an illustrated key to the species are presented. Lectotypes are designated for M. tintinnabulum, M. crispatus, M. dorbignii, M. coccopoma (Darwin), M. spinosus (Chenu), M. validus (Darwin), and M. ajax...

Kunstmatige substraten als standaard-monstermethode voor macrofauna in sloten. Een onderzoek in de Volgermeerpolder

Autores: Brinkkemper, Otto.
This report, deals with a research about the applicability of artificial substrates as a standard sampling-method for macrofauna. Macrofauna is considered as the macroscopic invertebrate fauna in aquatic ecosystems. The artificial substrates, open steel constructions filled with roofing-tiles, were placed at five sampling-sites at successively greater distances from a dumpsite for waste products in the “Volgermeerpolder”. Between ca. 1960 and 1969 apart from domestic waste also chemical waste was dumped here. This chemical waste was a by-product in the production of pesticides. The poisonous particles also occur in the water and the silt, near the dumping ground. Heavy metals also reach high concentrations near this place. Therefore in this research the...

Blume’s ’Mélanges botaniques’ effectively published in 1855

Autores: Steenis, C.G.G.J.van.
During the preparation of a rather substantial biographical sketch of C.L. Blume intended as the Dedication to volume 10 of the Flora Malesiana which will also contain a complete bibliography of his works, there was one dubious item, the ’Mélanges Botaniques’. Although names of new taxa from it were supposedly validated by Walpers (Ann. 4, 1857, 642—644) and a rather large extract from it was published in an unsigned review in Flora 41 (1858) 254—2, no effectively printed copies of this pamphlet were known to exist. Various comments on this enigmatic paper have been given especially with regard to the source: was the review made from a manuscript, from proofs, or from actually printed matter? As nobody had ever seen a printed copy it was concluded by...

Check Lists of Indonesian Trees under editorship of Dr. T.C. WHITMORE (OXF) and Dr. I.G.M. TANTRA (Forest Dept., Bali). In April 1986 the list for Sumatra was ready to be printed. The lists for Celebes and Nusa Tenggara were in the typing stage. Manuscripts for the Moluccas, Borneo and New Guinea are virtually complete. The project has prematurely ended, however, due to a drop of 40% in the Indonesian development budget. It is to be hoped that this is temporarily so and that the pieces can be picked up again in the future.

Autores: Raven, J.G.M.
A review is given of the distribution of Chondrinidae species in the Cantabrian Mountains. Few species occur in that area, Chondrina kobeltoides being the only endemic. Chondrina kobelti and C. kobeltoides are discussed and their characters are compared in a table. The taxon cliendentata is considered to be a subspecies of C. kobeltoides and not of C. kobelti as which it was originally described.

In the present paper the north-eastern Atlantic Chalinidae (Porifera, Demospongiae) are systematically revised and redescribed; where necessary lectotype designations are made. Three genera are recognized, viz. Haliclona, Acervochalina and Dendroxea. The latter genus is not represented in the study area. Seventy-two nominal species have been described in Haliclona in the wide sense here employed (including species assigned to other genera here considered junior synonyms of Haliclona: Reniera, Gellius, Adocia, Toxadocia, Orina). Among these 72 nominal species 12 valid species are recognized. One species new to science is described, viz. Haliclona xena spec, nov.; 4 nominal species of Acervochalina are reduced to 2 valid ones.

Systematics, Phylogeny and Biogeography of the chiefly Afromontane Genus Chondrolepis Mabille (Lepidoptera : Hesperiidae)
Provedor de dados: 16
Autores: Jong, R. de.
The five known species of the African genus Chondrolepis Mabille are extensively described and figured and two new species are added. Keys are given to the males and females separately. Most species are restricted to montane habitats, mainly in East Africa. Based on their phylogeny the geographic history of the species is analyzed. It is concluded that the distribution agrees with the predictions to be derived from the hypotheses that montane forests were very much restricted during the last Glacial Period of the Northern Hemisphere, later on becoming more widespread than at present, and that the contact between the Cameroun highlands and the highlands of East Africa was through species that temporarily lived in the intervening lowland forests and not...

Observations on the light-inhibited activity cycle and feeding behavior of the hydromedusa Olindias tenuis
Provedor de dados: 16
Autores: Larson, R.J.
Olindias tenuis is a shallow-water hydromedusa from the Caribbean that during the day is cryptic, residing among seagrass and algae, and after sunset swims into the water column. The medusae forage by swimming towards the surface, and then slowly drifting downwards with the exumbrella uppermost and the long primary tentacles hanging below. Positive buoyancy of the umbrella reduces the sinking rate. Both the activity cycle and buoyancy appear to be regulated by light, since the intensity of light alters the normal activity cycle both day and night. Feeding occurs once the medusae have entered the water column. At Puerto Rico, Olindias fed mostly on calanoid copepods; but chaetognaths, polychaetes, fish larvae, and amphipods are also consumed. Possible...

Ultrastructure of the ascus top and the ascospore wall in Fimaria and Pseudombrophila (Pezizales, Ascomycotina)
Provedor de dados: 16
Autores: Brummelen, J. van.
Morphological and developmental studies on the ascus top and the ascospore wall of Fimaria theioleuca, F. cervaria, Pseudombrophila obliquerimosa, and P. deerata were carried out with light and electron microscopy. Ascus tops are found with roughly delimited ascostomes and opercula, without indentations, preformed weakened zones, or subapical rings. Dehiscence of the ascus takes place in an eroded, slightly thinner zone of the outer layer and next to a corresponding wrinkled region in the inner layer. This corresponds with the structure and dehiscence mechanism found in genera of Pyronemataceae studied thus far. During ascospore development in all species at first a smooth electrondense secondary wall is formed. In F. theioleuca and F. cervaria this layer...

Autores: Loevezijn, G.B.S. van.
The Asturo-Leonese Basin is one of the three large palaeogeographical units of the Cantabrian Zone. In the north the basin is bounded by the Asturian Geanticline and the Palencian Basin. In the south the Palaeozoic succession is covered by Mesozoic and Tertiairy deposits. The Upper Devonian to lowermost Carboniferous succession of the Asturo-Leonese Basin includes the Nocedo Formation with the Gordón and Millar members, the Fueyo and the Ermita Formation. In these units, eight facies and ten subfacies are distinguished. The sediments of facies a, b, c2, c3, and cr are grouped in an inner shelf cluster, whereas facies cl, e, f, and g are grouped in an outer shelf cluster.

A revision of the genus Inocybe in Europe. I. Subgenus Inosperma and the smooth-spored species of subgenus Inocybe
Provedor de dados: 16
Autores: Kuyper, Th.W.
Fries (1821: 11) established Agaricus series Derminus tribus Inocybe, which was later elevated by him to generic rank (Fries, 1863: 346). Originally Fries based his circumscription of Inocybe solely on macroscopical characters; when it was raised to generic status Fries added that the spores of all Inocybe species were seemingly rough (’sporae scabrae videntur omnibus Inocybis communes’). Almost certainly this was not based on original observation, as Fries considered the use of the microscope unnecessary, but the result of an uncritical appraisal of observations by Berkeley (1860). The relevance of Fries’s statement regarding the typification of Inocybe is discussed on p. 29. Although the genus Inocybe is easily recognisable by macroscopical characters,...

The interest of the second author in the variability of Melongena melongena (L.) was aroused by the discovery of a population of dwarf specimens living in shallow tidal pools connected with the mangrove lagoon of Lac, Bonaire, in 1976 (see Figs 1-4). Further collecting resulted in bringing together a rather large number of recent and subrecent shells from various Caribbean localities which served as a base for the present study (see Appendix).

As far as the Netherlands are concerned, Rosa pimpinellifolia has a typically coastal distribution. Formerly, especially in the 19th century, the species had been collected a few times in the interior, but these finds might have been garden-escapes. A recently discovered habitat near Lemele (table 1), however, supports the hypothesis that the species really is indigenous on the sandy soils of the central and eastern part of the country.

The autecology of the edible oyster Crassostrea cucullata Born, 1778: size related vertical distribution at Mkomani, Mombasa
Provedor de dados: 20
Autores: Ruwa, R.K.; Okemwa, E.; Polk, P.
The littoral oyster Crassostrea cucullata occurs between 1.05-3.35 m above chart datum with the highest density occuring between 1.85-2.75m. Its distribution is size-related as demonstrated by computation of correlation coefficients (r) and regression equations. The shell lengths (i.e. maximum linear dimension) decreases in an upshore direction. The analysis show high r-values which are significant at P&lt;0.001. The elevation and density related effects on the shell lengths of the oysters are discussed.

Since 1983, tuna purse seine fishery has increased rapidly in the Indian Ocean. This fishery, being mostly based in Seychelles, represents an excellent opportunity to this country. However, it is essential that a good management strategy be adopted in order to ensure the rational exploitation of the resources. Since this fishery is in its early stage of development, it is not yet possible to obtain an accurate assessment of the stocks based on usual stock assessment methods. Nevertheless, from existing knowledge on the Indian and Atlantic oceans, a preliminary analysis of the resources is attempted. Of the two stocks studied, the skipjack, known as an opportunist species, can support a higher exploitation rate than the yellowfin. It would seem that catches...

Interview data, length frequency data and species composition for the Gulf of Guayaquil between 1974 and 1985 were examined. The data indicates a long term decline in landings of some 1,000 mt. The species most affected is Penaeus occidentalis which has shown an overall decline in landings. Landing Penaeus vannamei have increased in over the same period. It is not clear wether the decline in catches during 1984 and 1985 was due adverse enviromental conditions or overfishing by the fleet and postlarval.

The contents of this document relate principally to a proposal for an autonomous Marine Resources Research Centre in Mauritius. The Consultant concluded that such a Centre lacked Justification at this time. The priority marine resources research was identified as being concerned with fisheries, mariculture and environmental studies (of the lagoon surrounding Mauritius). Most of these activities are already being undertaken within the Fisheries Research and Development Division (Ministry of Agriculture, Fisheries and Natural Resources). It Is proposed that this arrangement continue- but that the Division be re-organized to form part of a broader fisheries department type structure.

Variación mensual y mareal del zooplancton en una estación fija del estero del Muerto, Golfo de Guayaquil
Provedor de dados: 20
Autores: Arcos, F.; Martínez, L.
Durante los meses de Marzo de 1983 a Febrero de 1984, se llevaron a cabo muestreos de 24 horas consecutivas en las fases llenas lunares en una estación fija en la región interior del Golfo de Guayaquil. Con esta información se han determinado variaciones mensuales y mareales del zooplancton, así como de otros parámetros ambientales, encontrándose una estrecha relación entre la abundancia de organismos y los valores de salinidad. La mayor biomasa planctónica estuvo asociada con los meses secos de alta salinidad. Analizando la variación mareal, se ha determinado que durante las mareas, existe aporte de material nutritivo desde el interior del estuario hacia la región exterior.

Fish and shellfish samples for total mercury analysis were provided by the local fish export industry. Data collected through the years 1981-83 are processed and information was obtained on actual total mercury values in edible muscle of sampled species. On the basis of these results, future trends in mercury concentration values are hoped to be predicted. The authors suggest a revision of standards in force at present and the proposal of new ones, taking into account species involved and size of specimens.

The equation log W=a+bL (where W=dry weight in ug, and L=total length in mm)was used to describe the growth in weight of larval anchovy collected in two areas of the Argentine sea, sampled in different months and several years. Regression lines were compared by covariance analysis applied to two size groups, namely larvae less and over 10 mm total length, as an evident break in the slopes indicated the existence of a chenge of rythm in the trajectory of larval growth in length. Significant differences between the slopes of the growth lines were observed within the smaller size group. No regional or yearly differences could be established fo larvae larger than 10 mm.

During the spring (H-04/82: october 11-27, 1982)carried out by the Fishery Research Vessel "Dr.E.Holmberg", the distribution of temperature, salinity, nutrients concentration and photosynthetic pigments were studied at the "Rio de la Plata" maritime front. The presence of Sub-Tropical coastal waters in only station did not allow its characterization. Low Chlorophyll a concentration were noted, in association with scarce concentrations of nutrients and high Margalef index values.

An analysis is presented of reproduction aspects of Argentine Sea blue whiting. The species spawns in the study area mostly during August and September, although some spawners have been detected even in November. Total length at 50-per-cent maturity was 35,4 cm for the males and 38.0 for the females. Significant differences between the length of maturity for individuals of the continental shelf compared to those of the slope, have been obtained. The southern blue whiting is a discontinuous spawner, showing one annual reproduction peak. Fecundity was investigated on the basis of samples collected in 1978 by the RV"Walther Herwig" and "Shinkai Maru". A significant positive correlation was also observed at relating oocyte dry weight and gonad factor, whereas...

Autores: Ercoli, R.
A practical and simple technique which gives an aproximate solution to the determination of minimum length of warp payed out durin a demersal or botto,m trawl operation es proposed. The method takes into account such variables as: weight in the water of warp payed out, of the otter board an the maximum trawling speed determined for each vessel in particular. The FRS "Dr. E.L. Holmberg" of the National Institute for Scientific Research and Development (INIDEP, Mar del Plata)was used to test the method.

The fishing of the mussel (Mytilus edulis platensis)off the Buenos Aires coast was alternatively carried out over two main grounds: "Faro Querandí" and "Quequén". The fluctuations of fishing periods on these grounds must have been determined by economic considerations. An abandoned bed may be considere, for practical purposes, depleted.The understanding of the dynamics of this spatially distributed stock could enable us to link more closely the biological cycles with those of the fishing activity. Rotative fishing is suggested as a managment strategy for this fishery.

Autores: Bertolotti, M.I.; Manca, E.A.
The anchovy (E.anchoita)is one of the most abundant species in the Argentine Sea. Distributed in between latitudes 34°S and 48°S, it has only been caught, traditionally, along the coasts of Buenos Aires Province - particulary in the vicinity of Mar del Plata. Anchovy-like items are exported both to producing and consuming countries. During the last three years markets have been lost. In order to regain them and to develop new ones, particularly in Europe it shall be necessary to compete with products that are well-priced and of the high quality and have a substantial aggregate value. The anchovy domestic market could be enlarged- with certain limitations- be developing new products.

Durante el período 1984-1985 se realizaron estudios geológicos en el sistema estuarino Estero Salado - Río Guayas, los mismos que comprendieron trabajos de geomorfología, geofísica (sísmica) y sedimentología. Los resultados de esas investigaciones, que se presentan en este artículo, llevan a establecer las diferencias existentes entre el Estero Salado y Río Guayas como consecuencia probable del mayor aporte de sedimentos y corrientes de agua recibida por el Río Guayas, y de la carga adicional de sedimentos por la construcción de camaroneras y tala de manglares.

"El Niño" 1982-83 respondió a un patrón de formación diferente a aquel que había sido característico para los fenómenos anteriores, a tal punto que sobrevino en forma sorpresiva y como una consecuencia de las fluctuaciones climáticas relacionadas con la oscilación Sur. Su desarrollo se inició en Junio de 1982 y no llegó a la costa ecuatoriana sino hasta Octubre, aunque en agosto ya se sentían sus primeras manifestaciones como la tendencia del Frente Ecuatorial a desplazarse hacia el sur y la profundización de las isotermas y la termoclina. En Noviembre el fenómeno estaba en pleno desarrollo en las aguas nacionales y en enero llegaba a la máxima intensidad, para posteriormente notarse un ascenso paulatino de las isotermas y termoclina, aunque las...

An extensive area of the continental shelf -between 37°20' and 34°40'S - was reviewed through hidroacoustical methods in order to evaluate the anchovy biomass. Within the area of highest concentration, further data on anchovy abundance were recorded, and fish samples were taken. Large anchovy shoals were located at about 170 nm from Mar del Plata, mainly in zones with sharp changes in oceanographic conditions. The distribution of the species was not uniform, but "contagious", and the log-normal distribution provided the best fit for the echo-integrator recorded data. The biomass was estimated at 1,061,727 tons (Confidence limits in between 921,010 and 1,223,930 tons). Some parameters of the population were estimated, such as: lenght-weight relationship,...

Twelve sulfated oils were prepared from Argentine's raw fish oils, and three more from samples previously bleached. The samples were taken montly during a year at a factory in the Mar del Plata (Argentine)zone. Each oil and its sulfated derivative was analyzed in its physico-chemical properties. The hydrophilic and hydrophobic fractions were separated and the fatty acids composition of the latter were determined. From the results obtained, it is possible to conclude that the Argentine's fish oils sulfated will be able to be used in fat-liquoring of leather.

Estudio comparativo de caracteres merísticos y morfométricos de la anchoíta (Engraulis anchoita)
Provedor de dados: 20
Autores: Ratti, M.M.
The argentine anchovy (E.anchoita)shows a distributional area between 35° and 47°30' on the continental shelf off Argentina. This paper deals with some meristic and morphometric characters in order to test their power in separating different stocks. Those largely scattered distributions of morphologic features, which had been already pointed out other authors, make difficult to separate different stocks of this species on this basis.

Autores: Bostock, T.; Camba, N.
El volumen de venta de sardina y macarela enlatada para consumo nacional en el año 1984 era 9.349 tm1 de acuerdo a estadísticas oficiales. Es notable que estos productos se consumen en alrededor de un 70% en las áreas rurales (private communication), sobre todo en la Costa. Parece que el alto grado de aceptabilidad se debe a su conveniencia y factibilidad de manejo sin enfriamiento, su buena disponibilidad y su bajo costo relativo a otros alimentos proteícos. Sin embargo, aunque el pescado enlatado es todavía la fuente de proteínas más barata que está fácilmente disponible a todo el país, el costo del envase encarece en gran medida este tipo de alimento. Cuesta tres veces o más que todos los demás ingredientes y representa cerca del 40% del precio del...

Marine botanical resources of Kenya coast
Provedor de dados: 20
Autores: Ruwa, R.K.
Investigations have shown that Kenya coast botanical resources are     underutilized and have not been realized as exploitable resources.     Apart from the mangroves which are heavily exploited, algae and marine     angiosperm resources are the least exploited. In a step to realize     these as future exploitable resources their current uses in Kenya and     how they could be used is discussed. A review of research work which     could be seen as a prelude to further research is also included.

Estudio de las concentraciones de los ácidos nucleicos (RNA, DNA)en músculo blanco e hígado de la lisa (Mugil brasiliensis)a lo largo de sus períodos de reposo y maduración gonadal
Provedor de dados: 20
Autores: Duhalde, G.B.; Introzzi, A.E.
The concentration of nucleic acids (RNA and DNA)was reviewed, as well as the RNA/DNA coefficient, in white muscle and liver of Mugil brasiliensis adult females caught at the Mar Chiquita Coastal Laggon (37°30'S, 57°20'W)between September and March. Countrary to what observations in other species (Lepomis macrochirus and Clarias batrachus)have shown, i.e., a decrease in muscle RNA/DNA during gonadal maturation, Mugil brasiliensis would seem to maintain a proteic balance in equilibrium during the said period. No significant correlation was found between IGS and the RNA, DNA and RNA/DNA muscular variables.

Catch per unit effort (CPUE), lenght distribution, age, growth, reproduction, migrations and feeding were studies through samples collected with longlines and a gang of gill-nets of several mesh size. CPUE data showed a progressive decrease of the relative abundance in the Río de la Plata, during the study period. Age was studied from scales. Back-calculations of growth revealed the pressence of Lee's phenomenon. Means lenghts at age were greater in females. No significant difference was found in lenght-weight regressions from both sexes and sampling areas. Only young individuals from 1 to 6 years were caught. None of the fish studied had ripening gonads. Extensive migrations were recorded both in the Paraná and Uruguay rivers. Stomach contents analysis...

In order to determine the distribution patterns of phytoplanktonic and zooplanktonic species that constitute the main food of the argentine anchovy (Engraulis anchoita), a study was made within a coastal spawning area on meso-scaled space (approximately 7 miles between stations). It was observed the predominacne of the copepod Oithona helgolandica and copepodites stages of other small-sized species, thus inferring the preponderance of nauplii stages which constitute the main food of early anchovy larvae. A high spatial heterogeneity was found in the distrtibution of both phytoplanktonic and zooplanktonic communities. Phytoplankton showed a patchiness distribution both in horizontal and vertical directions. Diatoms, dinoflagellates and coccolithophoirids...

Provedor de dados: 20
Autores: Gru, D.L.; Hansen, J.E.
Results of a research cruise carried out to estimate some biological parameters of anchovy (Engraulis anchoita), during the major spawning season, were analyzed in order to determine the minimum number of samples required to obtain unbiased values. Twelve samples of fishes were taken within an area of 607 nm². Size (total length)distributions, slope of the length-weight relationship, sex ratio and age population structure were considered. Results suggest that those parameters should be estimated by eight or more samples (corresponding to 76 nm² each).

This work was carried out in order to analize the ship incorporation history to the Argentine fishery fleet and the ship building policies in Argentine shipyards and ship importations. From fresher trawler fleet and freezer trawler fleet analysis we estimated optimun catch, possible catch, and natural stock for each fleet. A modern fresher fleet might reach the present value of the optimun catch, but it would not satisfy the total inshore fish factories demand unless equitable ratio between the optimun catch capacities of the fresher trawler fleet and the freezer trawler fleet be established.

Fish processing and distribution in Kenya
Provedor de dados: 20
Autores: Nzioka, R.M.
Kenya has a potential to land 150,000 metric tons of fish annually     worth U.S. $50 million. The present annual fish landed is about 50,000     metric tons worth U.S. $16.7 million. Some of the fishing areas are     near the main urban centers and fish landed is disposed of fresh.     However, due to preservation and communication difficulties, fish from     areas that are far from population centers are processed. About 5% of     the annual total catch is processed as salted, sun-dried, smoked,     chilled, frozen and filleted and as fish meal.

Determinación del datum vertical en La Libertad, Ecuador
Provedor de dados: 20
Autores: Paredes, N.
Normalmente en los levantamientos geodésicos se utilizan dos tipos de referencias: las coordenadas de origen y el datum vertical: Las primeras están en función del elipsoide o superficie matemática de referencia que más se ajusta al área, y el segundo; por la determinación del nivel medio del mar con 19 años de observación. El Ecuador tiene como elipsoide de referencia, el Internacional y el datum horizontal del punto localizado en la Canoa, Venezuela (Provisional South American Datum 1956, PSAD 56), cuya coordenadas han sido transportadas a nuestro país mediante redes geodésicas. En 1948, el Ecuador instaló una estación mareográfica en la Libertad (Lat. 020° 12'S., Long. 80° 55'W) y a la determinación del datum vertical se refiere el presente trabajo.

Seychelles tuna bulletin : third quarter 1986
Provedor de dados: 20
The number of purse seiners active in the Western Indian Ocean during the third quarter of 1986 stabilized at 33 vessels.  This is comparable to the 34 vessels licensed in September of last year.  As determined from purse seiner logbooks collected up to the end of September, catch rates improved considerably from the first and second quarter 1986 though not reaching the level of the first quarter of 1984.  The proportion of yellow fin in the catch was also lower than the previous years. In the first half of 1986, the seasonal variation in the distribution of fishing effort and in the species composition of the catch differed from previous years.  In the past, yellow fin was the dominant species from November through July, at this period most of the fleet...

Endangered fish species of Kenya's inland waters with emphasis on Labeo spp
Provedor de dados: 20
Autores: Kibaara, D.
The importance of water masses, natural or otherwise, in supporting     fisheries, and the importance of fish as human food, cannot be     overemphasized. The inland waters of Kenya act as habitats for fish,     harbouring many different fish species. It has been observed with     interest that certain fish species have decreased in numbers over the     years within the inland waters. The decline has been at a rate which,     if left unchecked, will eventually cause total disappearance of the     species concerned. Thus those species have been correctly termed     "endangered". Among them are Labeo, Schilbe, Alestes, Clarias and     Barbus spp.

La pesca de especies pelágicas pequeñas es para el Ecuador un recurso masivo el cual se aprovecha en más de un 90% para la elaboración de harina de pescado, usada en la alimentación de animales. A pesar del bajo valor de estas especies, cantidades insignificantes de las mismas entran al comercio de pescado fresco, el cual está dominado por especies con un menor contenido de grasas. A cambio se comercializa una cantidad apreciable en productos enlatados (9,349 tm en 1984 solo para el mercado nacional), pero se limita el consumo entre los sectores de más bajos ingresos, a causa del alto costo del envase de hojalata. Este factor favorece la elaboración de un producto salado que no necesita un envase caro para su conservación. Hasta ahora se han identificado...

A re-evaluation of marine nematode productivity
Provedor de dados: 27
Autores: Vranken, G.; Herman, P.M.J.; Vincx, M.; Heip, C.H.R.
Nematodes are the most abundant multicellular animals in marine sediments but their role in the benthos has not been properly quantified yet. In nearly all energy-flow budgets of marine systems their annual production P is given as about nine times their biomass B and their part in the total energy-flow is consequently estimated as anywhere between 3 and 30% of the total (carbon) input in the benthic system. Our laboratory experiments demonstrate that nematode productivity is much higher than P/B ~ 9 per year and may reach values of over 60 for bacterial grazers. To obtain more reliable estimates for field populations we propose a regression equation relating egg-to-egg development time T&lt;sub&gt;min&lt;/sub&gt; to temperature (t) and adult female weight...

Classification of estuarine particles using automated electron microprobe analysis and multivariate techniques
Provedor de dados: 27
Autores: Bernard, P.C.; Van Grieken, R.E.
The suspended particulate matter from a series of stations in an estuary is automatically analyzed for 11 elements on a particle-by-particle basis by using electron microprobe X-ray microanalysis and an automatic image analysis system. The interpretation of the large acquired data set implies numerical multivariate analysis. The developed procedure consists of using cluster analysis on the particles of individual samples, followed by nearest centroid sorting over all samples from the study area. For the Ems estuary, the procedure provided 13 geochemically different particle types of which the relative abundance through the estuary could be followed and interpreted in terms of estuarine mixing processes. The presented methodology could be applied in other...

Autores: Martens, E.E.
The ultrastructure of male copulatory organs having a stylet has been studied in some genera of the Proseriata. Within the Monocelididae there was a variety of stylet-like hard structures. The stylet in &lt;i&gt;Monocelis fusca&lt;/i&gt; was a differentiation of the basement membrane of the epithelium lining a penis-like muscular papilla. The penis papilla in &lt;i&gt;Ectocotyla&lt;/i&gt;consisted of circular muscles surrounded by a thickened basement membrane and an epithelium. &lt;i&gt;Archilopsis sp.&lt;/i&gt; and &lt;i&gt;Archilina sp.&lt;/i&gt; with a duplex copulatory bulb, had a stylet within a spiny cirrus. The stylet structure in &lt;i&gt;Archilina sp.&lt;/i&gt; was composed of four long spines which were derivatives of the basement membrane....

Toxicity of copper, mercury and lead to a marine nematode
Provedor de dados: 27
Autores: Vranken, G.; Heip, C.H.R.
Toxicity of copper, lead and mercury to the nematode &lt;i&gt;Diplolaimella&lt;/i&gt; spec 1 is studied. Mortality responses obtained demonstrate high resistance to heavy metals. Population growth parameters as the intrinsic rate of natural increase and net-reproductivity are significantly depressed at copper-concentrations which cause no juvenile mortality. The lowest concentrations tested caused significant inhibition of development rate in both sexes. For this particular nematode species suppression of fecundity and developmental inhibition are more reliable criteria, determining non-exceedable limits with regard to environmental safety. Our tests show that nematode productivity may be significantly depressed at copper levels found in some areas of the...

The predictability of biological populations and communities: an example from the meiobenthos
Provedor de dados: 27
Autores: Herman, P.M.J.; Heip, C.H.R.
The predictability of temporal changes was analysed in the population density of three meiobenthic copepod species, and for three parameters characterizing this community. For &lt;i&gt;Paranychocamptus nanus&lt;/i&gt; and &lt;i&gt;Tachidius discipes&lt;/i&gt; a large part of the variation in time scales longer than 1 year is explainable as cyclic factors. In &lt;i&gt;P. nanus&lt;/i&gt; clear cycles with periods of 2 years and 1.5 years were found. These cyclic factors can be extrapolated for prediction. In &lt;i&gt;Canuella perplexa&lt;/i&gt; almost all the variation was due to unpredictable long-term drift. Community parameters are generally better predicted than population densities. In our data set total density of the copepods was the best parameter to...

Gobies were obtained monthly from the bycatch of a commercial shrimp trawler operating in the shallow waters (less than 20m depth) of the Westdiep area, Southern Bight of the North Sea, from May through December 1984. &lt;i&gt;Pomatoschistus lozanoi&lt;/i&gt; juveniles appear later than &lt;i&gt;P. minutus&lt;/i&gt; juveniles, indicating a temporal segregation of reproduction. Yearly average density of &lt;i&gt;P. minutus&lt;/i&gt; is about twice that of &lt;i&gt;P. lozanoi&lt;/i&gt;. Food consumption by the two species amounts to 1-2 g AFDW/m&lt;sup&gt;2&lt;/sup&gt;/year.

The importance of turbellarians in the marine meiobenthos: a review
Provedor de dados: 27
Autores: Martens, P.M.; Schockaert, E.R.
Recent data and opinions on meiofaunal ecology are briefly reviewed; and from scattered data, the place of turbellarians in the meiobenthic community is discussed. Turbellarian diversity is of the same magnitude higher in sandy habitats than in muddy bottoms. In sand, turbellarian diversity is of the same magnitude as that of other important meiofaunal taxa, while densities range between 7-25% of the total meiofauna. Mean individual turbellarian dry weight seems to be four times that of nematodes and in sandy habitats turbellarian biomass may be equal to or exceed that of nematodes. Most turbellarian species may be considered as predators and in this respect may take the place occupied by macrofaunal species in muddy sediments.

ANALYZING THE EFFECT OF CHANGING FEED-BEEF PRICE RELATIONSHIPS ON BEEF PRODUCTION MANAGEMENT STRATEGIES IN HAWAII:  A DYNAMIC PROGRAMMING APPROACH
Provedor de dados: 31
Autores: van Poollen,   H. Walter; Leung,   PingSun.
A dynamic programming approach was used to evaluate the effect of changing the feed input to product price relationship on the beef production management decision process.  The dynamic programming model consists of nine submodels describing and analyzing the time-dependent beef production management decision process.  The model incorporates biological functions and economic principles.  Results clearly showed the importance of the feed-beef price relationships in management decision making.  Optimal beef production management strategies were generally consistent with beef production management practices followed in Hawaii under those feed-beef price relationships.

Reflections on Cooperation and Cooperatives
Provedor de dados: 31
Autores: Breimyer,   Harold F.
Cooperation is looked upon favorably because it connotes collective economic organization without duress or exploitation. This conceptualization may underlie most thinking about the place of cooperative organization in today’s society and the modern economy. Cooperation organizes economic activity on terms of equality at any stratum in the vertical sequence of producing and marketing farm products. Cooperatives’ government must no only be viable and functional but must incorporate democratic values. Boards of directors must be attuned to their members and effectively in control. The only valid defense of cooperatives is that they give reality to all that is good in cooperation.

A MONTE CARLO COMPARISON OF ALTERNATIVE ESTIMATORS OF AUTOCORRELATED SIMULTANEOUS SYSTEMS USING A U.S. PORK SECTOR MODEL AS THE TRUE  STRUCTURE
Provedor de dados: 31
Autores: Naik,   Gopal; Dixon,   Bruce L.
Monte Carlo analysis of the performance of alternative estimators of simultaneous system's coefficients in the presence of autocorrelation is performed.  The "true" underlying model is an estimated, three-equation, monthly model of the U.S. pork market.  Estimators for ex post forecasts are also compared.  Multicollinearity is found to be a salient characteristic likely adversely affecting estimator performance.  Results show that correcting for autocorrelation is desirable when levels of autocorrelation are high for both parameter accuracy and ex post forecasting.  However, the best structural coefficient estimator for high levels of autocorrelation is not necessarily the best estimator for ex post forecasting.

In this paper we estimate the price and income elasticities for five sweet spreads using a two-stage budgeting procedure.  The first stage modeled the consumer's budget decision as a Tobit model, where total sweet spread expenditures are based on income and demographic variables.  The second stage, including only those households with nonzero first stage expenditures, was treated as a standard consumer allocation problem using the AIDS model.  To incorporate population demographics, the AIDS model was expanded by specifying the constant term as a linear function of demographic variables.  The coefficients for the prices and expenditures are highly significant and demand is elastic for all five goods.  The most significant demographic effects are due to...

Autores: van Kooten,   G. Cornelis; Schoney,   Richard A.; Hayward,   Keith A.
Results of a study of goal orderings of Saskatchewan farmers who participate in the province's FARMLAB Program are presented.  We use the method of fuzzy pair-wise comparisons which allows the respondent to indicate a degree of preference between two alternative goal statements, thereby providing more information than in the binary case.  From survey data ratio-scale scores are constructed for eight goal statements, and these are regressed on a set of farm enterprise and household characteristics and a psychological locus-of-control (or I-E) score.  The empirical results indicate that goodness-of-fit measures are better than those obtained by other researchers, perhaps because a psychological measure (I-E score) is included as an explanatory variable for...

CHANGES IN TRANSPORTATION COSTS AND INTERREGIONAL COMPETITION IN THE U.S. APPLE INDUSTRY
Provedor de dados: 31
Autores: Dunn,   James W.; Garafola,   Lynn A.
An interregional competition model of the U.S. apple industry is constructed.  This model includes the consumer products of fresh apples, applesauce and apple juice.  The validation of the model showed that it did a good job of estimating consumer's quantity demanded and prices and a reasonable job of estimating utilization.  This model was used to study the effects of transportation cost changes on the industry in the short- and intermediate run.  The total production and consumption levels changed by moderate amounts with changing transport costs while the utilization of a region's crop was quite sensitive to such changes.

The system consists of two price-markup equations, two quantity-dependent demand equations and two inventory change identities.  The three-stage least squares estimation results tend to support the behavioral hypotheses.

A STOCHASTIC DOMINANCE ANALYSIS OF ALTERNATIVE MARKETING STRATEGIES FOR MIXED CROP FARMS IN NORTH FLORIDA
Provedor de dados: 31
Autores: Anaman,   Kwabena A.; Boggess,   William G.
Cumulative probability distributions of income for management scenarios involving four pre-harvest marketing strategies are subjected to stochastic dominance analysis to determine risk-efficient sets of strategies for different groups of farmers in North Florida. Results indicate that farmers should behave differently in their choice of marketing strategies according to their risk attitudes. Highly risk-averse farmers should prefer some forward contracting while low risk-averse and risk loving farmers should prefer cash sales at harvest. Use of the futures markets leads to both higher income and greater risk than forward contracting but lower income and risk than cash sales.

Effects of Federal Taxes on Member Cash Flows From Patronage Refunds
Provedor de dados: 31
Autores: Junge,   Katie A.; Ginder,   Roger G.
Scheduled changes in Federal Insurance Contributions Act (FICA) tax rates will affect member net cash flow when a patronage refund is received from a cooperative. Cash patronage refunds at the minimum 20 percent level generally required by law will create negative cash flows for patrons in very low tax brackets. Negative cash flows accumulated over the 10-year period 1980-90 may result in opportunity costs to patrons that exceed the value of the refunds. Boards will need to consider one or more of the following strategies to deal with this problem: (1) increased cash patronage refunds, (2) shorter revolving periods, and (3) use of nonqualified written notices of allocation.

A STUDY ON THE SUSTAINABILITY OF VILLAGE-BASED COOPERATIVES AS AN INSTITUTION OF DEVELOPMENT
Provedor de dados: 31
Autores: Hussein,   Maliha H.
The existing social and institutional structures at the village level are so occupied with immediate issues of survival that they have been unable to divert much of their energy to long term development goals.  The situation is characterized by the existence of "social traps" which lead people to adopt short term solutions and ignore the long term consequences of their actions.  At such low income levels future expected returns are also likely to be discounted at very high rates. It is a reflection of the state of affairs that very little new land was brought under cultivation since independence.  Individually, the farmers lacked the resources which could enable them to develop new land.  The opening of the Karakorum highway has created new economic...

COMPARATIVE ANALYSIS OF RICE PRODUCTION COSTS IN SMALL- AND LARGE-SCALE IRRIGATED PERIMETERS IN THE UPSTREAM ZONE OF THE FLEUVE, MAURITANIA
Provedor de dados: 31
Autores: Koita,   Tocka.
Some agricultural project analysts advocate that "small-scale" perimeters are more cost effective and successful than large ones.  Patterson argues that the small scale perimeter if potentially conducive to development because of their smallness and their flexibility in terms of innovations.  Morever a recent survey irrigation in the Sahelian countries by Stryker, Gotsch, McIntire and Roche, suggests that labor intensive schemes generally have better distributional characteristics than those that are more capital intensive.  These advantages attributed to the small schemes have even biased some donors towards funding small scale perimeters. Efforts to expand rice production and therefore to increase self-sufficiency can be analyzed in terms of their...

Pasture Improvement Adoption In South-Eastern New South Wales
Provedor de dados: 31
Autores: Vere,   David T.; Muir,   A.M.
Pasture improvement is said to be the technology which has most influenced Australia's post-war agricultural production but little is known of the factors which have influenced the pasture adoption process. This paper describes an exploratory analysis of the determinants of pasture improvement adoption on the central and southern tablelands of New South Wales, one of Australia's foremost grazing areas. The objectives were to quantify the separate influences on pasture improvement adoption and to determine whether there has been change in the response to these influences over time. The results indicate that most of the variation in improved pasture levels since 1950 was explained by movements in farm prices and input costs. Other periodic influences were...

Targeted Agricultural Export Subsidies and Social Welfare
Provedor de dados: 31
Autores: Abbott,   Philip C.; Paarlberg,   Philip L.; Sharples,   Jerry A.
Most agricultural export subsidies are targeted to specific countries. This paper demonstrates that in a standard general equilibrium model of international trade, a small targeted subsidy increase the welfare of the subsidizing country by exploiting differences in price responsiveness of demand relationships of importers. A single-product spatial equilibrium model then is used to show that targeted export subsidies can be used to increase the subsidizing country's welfare by exploiting transportation cost differences and the elasticity of excess supply of competitors or of markets supplied by competitors through subsidization of shared markets. In addition, an empirical model of the world wheat market is used to illustrate the theoretical conclusions.

STATISTICAL SIGNIFICANCE AND STABILITY OF THE HOG CYCLE
Provedor de dados: 31
Autores: Shonkwiler,   John Scott; Spreen,   Thomas H.
Cyclical fluctuations in prices and production have long characterized the United States hog industry. Recent evidence suggests that the length of the hog cycle has changed. In order to determine whether the change in cycle length is statistically significant, the bootstrap technique is employed to derive confidence intervals for point estimates of the hog cycle. Application of the bootstrap technique to time series models is discussed and empirical results are presented. It is concluded that the hog cycle is undergoing rather complicated changes based on cycle lengths that are calculated to be statistically different from zero.

LABOR ALLOCATION STRATEGIES OF SEMI-SUBSISTENCE HOUSEHOLDS IN WEST AFRICA:  A CASE STUDY OF THE DIOLAS OF THE LOWER CASAMANCE REGION OF SENEGAL
Provedor de dados: 31
Autores: Dedegbe,   Danielle.
For the great majority of small scale farming households in West Africa, labor is one of their most crucial factors of production.  Yet, the dynamics behind these households' patterns of labor allocation are not well understood by planners and policy makers.  This study argues that (a) a household's labor allocation behavior is determined by its real opportunity set vis-a-vis the household's basic objectives, (b) a household's real opportunity set is the sum of its main constraints and opportunities after all environmental dimensions have been simultaneously considered, (c) male and female household members do not have the same opportunity sets.  The environmental circumstances of the Diola and Mandingized Diola farm households from the Casamance region of...

Assessing Accuracy of Livestock Market Reporters: Some Evidence on Pigs in Victoria
Provedor de dados: 31
Autores: Alston,   Julian M.; Nguyen,   S.T.; Tunstall,   Allan W.
This paper explores the hypothesis that livestock market reporters tend to err towards the middle of the actual range when estimating carcass weight and fat depth. Trial data for pigs support the hypothesis and indicate that reporters' estimates may be significantly biased in some extreme weight and fat classes even when the average errors taken across all classes are trivial. Significant distortions in the reported premiums or discounts between some fat and weight classes are implied by the errors in estimating fat and weight.

VALIDATION OF LINEAR PROGRAMMING MODELS
Provedor de dados: 31
Autores: McCarl,   Bruce A.; Apland,   Jeffrey.
Systematic approaches to validation of linear programming models are discussed for prescriptive and predictive applications to economic problems. Specific references are made to a general linear programming formulation, however, the approaches are applicable to mathematical programming applications in general. Detailed procedures are outlined for validating various aspects of model performance given complete or partial sets of observed, real world values of variables. Alternative evaluation criteria are presented along with procedures for correcting validation problems.

CHANGES IN SELECTED CHARACTERISTICS OF U.S. FARMS DURING THE 1970s AND EARLY 1980s: AN INVESTIGATION BASED ON CURRENT AND CONSTANT DOLLAR SALES CATEGORIES
Provedor de dados: 31
Autores: Zulauf,   Carl R.
Changes since 1970 in the distribution of selected farm characteristics among constant and current dollar farm sales categories were examined. In general, the same trends emerged but changes were less dramatic after adjusting for inflation. The increasing concentration of net farm income among farms with sales exceeding $500,000 was attributed in part to their continuing high ratio of gross farm income to expenses (approximately 145 percent). Farms with sales between $10,000 and $500,000 became more dependent on nonfarm income. This dependency is postulated to result from a farm income treadmill and use of nonfarm income to cope with the treadmill.

HOW TO PAY FOR AGRICULTURAL INCOME SUPPORTS
Provedor de dados: 31
Autores: Runge,   C. Ford.
This paper examines the impact of deficit reductions on agricultural price support spending, and proposes several policy innovations designed to remove agricultural programs from the entitlement category. First, agricultural program costs are analyzed in relation to deficit reduction requirements resulting from recent legislation. Second, price support and food stamp programs are proposed as a separate budget category to be financed through an excise tax on retail food sales. Third, the incidence of this tax on consumers is considered, and compensation for lower income groups is proposed via expanded eligibility for the food stamp program. A final section presents some conclusions for policy.

ANALYZING TENURE ARRANGEMENTS AND CROP ROTATIONS USING FARM SIMULATION AND PROBIT ANALYSIS
Provedor de dados: 31
Autores: Perry,   Gregory M.; Rister,   M. Edward; Richardson,   James W.; Grant,   Warren R.
Whole farm simulation analysis and econometric techniques are employed in an analysis of crop rotations and tenure arrangement strategies. The FLIPSIM model is used to analyze a representative Texas Upper Gulf Coast rice and soybean farm. Probit analysis is then used to determine the impact of net cash farm income, land tenure, and crop rotation on probability of survival. Results suggest that, although the simulation model is useful in providing information on the effect at the farm level of following the different strategies, probit results provide greater understanding into the returns and risk inherent to each strategy.

U.S. Cooperatives and the Potential for Grain Exports to Eastern Europe
Provedor de dados: 31
Autores: Bunker,   Arvin R.; Jones,   James R.
Cooperatives are major participants in grain production and marketing in the United States and Soviet Bloc countries. U.S. cooperatives, for example, receive more than 40 percent of off-farm grain sales, while cooperatives in most Soviet Bloc countries account for more than two-thirds of grain production. Despite this heavy involvement, trade between cooperatives in these regions is nil. U.S. cooperative exports to Soviet Bloc import organizations are also limited. Import decision making in Soviet Bloc countries is described and buyers’ concerns are evaluated against exports services offered by U.S. cooperatives. Exports to Soviet Bloc countries by U.S. cooperatives will remain limited unless cooperatives offer delivered sales, bids on large tenders, and...

MODELING AGRICULTURAL WATER MARKETS FOR HYDROPOWER PRODUCTION IN THE PACIFIC NORTHWEST
Provedor de dados: 31
Autores: Houston,   Jack E.; Whittlesey,   Norman K.
More than two-thirds of Pacific Northwest electricity is produced from hydropower on the Columbia River system.  Irrigated agriculture in the region has a large impact on power supplies by diverting water that could be used for hydropower and using electricity for pumping the water.  This paper examines the potential for water markets that would permit sales of water from agriculture to the hydropower sector for energy production.  It is shown that both farmers and energy consumers could be made better off by adopting water markets to reallocate water among these competing uses.

DEMOGRAPHIC VERSUS MEDIA ADVERTISING EFFECTS ON MILK DEMAND: THE CASE OF THE NEW YORK CITY MARKET
Provedor de dados: 31
Autores: Kinnucan,   Henry W.
An advertising-sales response model is extended to include the effects of demographic factors (age and race) as additional determinants of milk demand.  Previous research indicates that the age structure of a population and its racial composition are primary factors influencing fluid milk sales.  Failure to incorporate these factors in the milk demand model results in a 30 percent downward biased estimate of the advertising effect.  Consequently, the economic effectiveness of milk advertising is understated when the effects of demographic variables are ignored.  Changes in demographic factors (growing nonwhite population and shrinking teenage market) appear to explain the relatively flat trend in per capita milk sales in the New York City market over the...

Provedor de dados: 31
Autores: Hertel,   Thomas W.; McKinzie,   Lance.
This paper argues that the use of "laboratory" data sets can add substantially to the teaching of production economics at the graduate level.  Optimal experimental designs for generating pseudo data from a process model are discussed.  These are shown to depend of the functional form to be estimated.  We choose the translog form for our multiproduct profit function and compare alternative approaches to estimation, using pseudo data from a farm-level linear programming model.  Particular restrictions on this profit function are also considered.  Finally, aggregation of output prices is shown to alter substantially input price elasticities of demand.

An example of agricultural researching technology transfer and implications for the fiscal coordination and conduct of agricultural research programs is presented.  Uniform Soybean Tests conducted in four Southern States are used to estimate the potential for transferability of soybean variety research among homogeneous sub-areas.  The results indicate a high degree of transferability among the sub-areas.  Coordinated management of soybean variety research could potentially provide more effective expenditure of soybean breeding research investments.  Additionally, the concept or research transferability is not limited to soybeans or soybean variety research.  Increased coordination of agricultural research investments by individual states may enhance...

Membership of the Southern Agricultural Economics Association (SAEA) was polled to ascertain the strength of support for changing the name of the Southern Journal of Agricultural Economics (SJAE) to eliminate the regional connotation.  The general view was that a name change is unwarranted.  The overall impression of our profession is that the SJAE is a high quality journal and that the name is not the crucial factor in promulgating this image but rather the continued striving for excellence.  A number of profiles were developed to show that the ordered-response model may be used in predicting probabilities for those who would or would not likely favor a name change.

HOUSEHOLD NUTRIENT DEMAND: USE OF CHARACTERISTICS THEORY AND A COMMON ATTRIBUTE MODEL
Provedor de dados: 31
Autores: Eastwood,   David B.; Brooker,   John R.; Terry,   Danny E.
A characteristics model, which assumes goods generate a common set of attributes but no unique attribute, is described. The model yielded two equations which were estimated. One was a set of hedonic price equations in which the price paid for each food purchased was a function of imputed attribute prices. This set of equations was estimated at the household level. Nutrient demand equations were estimated across households. Imputed prices, income, and household characteristics including location, size, education, age distribution, and race affected nutrient demand levels.

MONOPSONISTIC FOOD PROCESSING AND FARM PRICES: THE CASE OF THE WEST ALABAMA CATFISH INDUSTRY
Provedor de dados: 31
Autores: Kinnucan,   Henry W.; Sullivan,   Gregory M.
Increasing concentration in food processing has important economic implications for agricultural producers and consumers.  This paper addresses the issue by focusing on a case where pure monopsony conditions appear to hold-catfish processing in West Alabama.  Farm-level impacts of the market power imbalance are described via a six equation theoretical model.  Results show price elasticity of farm supply governing the economic incentive to the processor for exploiting its market power: less (more) elastic supply implies greater (lesser) divergence between competitive and monopsony price.  The theoretical model is operationalized using an indirect procedure recently suggested by Houck for estimating farm level supply elasticities.  Based on these supply...

EFFECTS OF PORT USER FEES ON EXPORT GRAIN FLOW PATTERNS
Provedor de dados: 31
Autores: Viscencio-Brambila,   Hector; Fuller,   Stephen W.
The purpose of this paper is to evaluate the effect of the proposed deep draft port user fee on export grain flow patterns and provide insight into potential marketing system adjustment costs which may result from diverted flows.  A multiperiod, network flow model is used to conduct the analysis.  Analyses show grain flow patterns to be affected most by a port specific fee which is based on weight.  The annual variation in flows generated by imposition of port user charges in generally less than the historical year-to-year variation and, in most cases, the altered port area flows can be accommodated by existing infrastructure.

Autores: Fischer,   Martin L.; Moore,   Karen.
A new credit scoring function for classifying Bank of Cooperatives loans, pricing loans based on credit risk, screening loan applications, and diagnosing credit weaknesses was estimated using stepwise logistic regression analysis. Two versions were estimated, dichotomous and polychotomous. The dichotomous model is judged superior for the above uses. The model was tested for validity for different types of cooperatives. In a combined estimating and test sample of 708 cooperatives, the model correctly classifies 92 percent of cooperatives in a 2-class system and 70 percent in a 4-class system.

On Resolving Multiple Optima in Linear Programming
Provedor de dados: 31
Autores: Drynan,   Ross G.
Although the solution to a linear programming problem is not necessarily unique, the theoretical and practical implications of multiple optima have not been thoroughly discussed by agricultural economists. Recently there have been calls for greater recognition, resolution and exploitation of multiplicity. In this note, it is argued that previous recommendations for resolving multiplicity are restrictive both procedurally and conceptually. An alternative and more general approach is outlined.

MANAGING NUTRIENT LOSSES: SOME EMPIRICAL RESULTS ON THE POTENTIAL WATER QUALITY EFFECTS
Provedor de dados: 31
Autores: Young,   C. Edwin; Crowder,   Bradley M.
Over-application of manure on cropland can cause water quality degradation.  This paper reports a modeling approach for assessing tradeoffs among manure storage and handling systems as they relate to the nutrient loadings in cropland runoff, including nitrate losses to groundwater.  The CREAMS simulation model provided estimates of nutrient losses.  A linear optimization model was used to determine the income-nutrient loss tradeoffs.  Six-month storage was profitable for farmers with average-size dairy herds, but compared to daily spreading caused increased nitrate leaching through the soil to groundwater resources.  Twelve-month storage systems decreased farm profitability while decreasing the total nitrogen losses from farm fields.

IMPUTED MISSING INCOMES AND MARGINAL PROPENSITY TO CONSUME FOOD
Provedor de dados: 31
Autores: Lee,   Jonq-Ying.
This study has demonstrated the use of a type 2 tobit model to impute the incomes for nonresponding households.  The imputed incomes generated from the type 2 tobit model for nonresponding households indicate that average incomes of nonresponding households are slightly higher than those of responding households.  Furthermore, this study demonstrates that under the assumption that the predicted incomes derived from the type 2 tobit model are accurate, the deletion of nonresponsidng households would cause an overestimation of the impact of income on food expenditures for households with annual incomes of less than $20,000.

WAGE DETERMINATION FOR REGULAR HIRED FARM WORKERS: AN EMPIRICAL ANALYSIS FOR GEORGIA
Provedor de dados: 31
Autores: Gunter,   Lewell F.
Regular hired farm workers, performing 150 days or more of farm work annually, became increasingly important in the 1970's. The number of regular hired workers in the United States increased by almost 50 percent during the decade, while the number of seasonal workers, operators, and unpaid family workers declined. Pricing of regular hired labor is investigated through estimation of three nested wage determination models in a case study analysis for Georgia. Micro-level data on individual workers were used to analyze the effects of general human capital, farm worker duties, local labor market conditions, and farm characteristics on wage rates.

The effect of risk aversion on Nash equilibrium trade restrictions is studied using numerical methods. An increase in a nation's level of risk aversion can lead to either an increase or decrease in its equilibrium restriction and either an increase or decrease in its rival's restriction. The linear quadratic dynamic game is generalized to include risk aversion.

TRANSPORTATION DEREGULATION AND INTERREGIONAL COMPETITION IN THE NORTHEASTERN FEED ECONOMY
Provedor de dados: 31
Autores: Randolph,   Thomas F.; Lee,   David R.
The effects of rail deregulation on feed transportation in the Northeast are examined through construction of a spatial equilibrium model of the Northeastern feed industry.  Short-run and long-run effects of deregulation are analyzed through incorporation of rail rate structures for 1981 and 1984, respectively, into model simulations and comparison with pre-deregulation base year results (1980).  The results show that the Northeast feed economy has generally benefited from rail deregulation which has led to lower transportation costs, lower feed costs and an enhanced competitive position relative to the Southeastern U.S.

SOME CURRENT ISSUES IN THE MARKETING OF AGRICULTURAL PRODUCTS
Provedor de dados: 31
Autores: Richardson,   Bob.
The subject of 'marketing' as a field of agricultural policy and applied research is discussed in this paper. Agribusiness approaches to marketing advanced in recent years are argued to have made little contribution to policy or research and are rejected in favour of the more traditional framework of applied economic analysis. Developments in government policy on national statutory marketing authorities for agricultural products are appraised along with some evidence on the allocation of research effort revealed in professional journals. It is argued that more research should be conducted on the impact of the promotion of agricultural products and on the efficiency and distributional impact of marketing policies of statutory marketing authorities.

Guaranteeing a Market and the Contracts of Bargaining Cooperatives
Provedor de dados: 31
Autores: Knoeber,   Charles R.; Baumer,   David L.
One important function of bargaining cooperatives is alleged to be guaranteeing a market for their members. We characterize this function as deterring opportunistic behavior by producers and processors operating under forward contracts. We then examine actual contracts of bargaining cooperatives and argue that certain clauses in these contracts serve to guarantee the market. These clauses are those that provide for mechanical or third-party grading, liquidated damages, and most-favored-customer treatment.

Over the years the Government of Tanzania has recognized the need for modern technology to increase agricultural production.  Since the colonial period, agricultural research institutions have been established to cover most of the ecological zones of the country and research had been carried out on major crops by these institutes.  However, recently critics have raised the question as to whether this research has been consistent with the needs of the majority of farmers.  Closely related to this is the question of how effective the research findings have been communicated to the farmers.  These questions have been raised due to the persistently low agricultural productivity and the use of traditional methods of farming, despite all the research that has...

COOPERATIVE LABOR ALLOCATION UNDER UNCERTAINTY
Provedor de dados: 31
Autores: Parliament,   Claudia; Tsur,   Yacov; Zilberman,   David.
Understanding the allocation of labor between collective and private activities within cooperatives has been an issue of interest for economists and policy makers.  This paper extends existing literature by incorporating income uncertainty from both private and collective activities, and by assuming that members are risk averse.  The analysis suggests a member's labor response to policy parameters can be decomposed into three components: the mean effect, reflecting the labor response under certainty or risk neutrality; the variance effect, reflecting the response to changes in risk; and the wealth effect, reflecting the response to changes in risk aversion associated with changes in wealth.  The analysis demonstrates the labor response may be reversed from...

PLANT NUTRIENT DEMAND FUNCTIONS FOR TENNESSEE WITH PRICES OF JOINTLY APPLIED NUTRIENTS
Provedor de dados: 31
Autores: Roberts,   Roland K.
Several studies have estimated plant nutrient demand functions for nitrogen, phosphate, and potash. All included own-price effects but excluded prices of jointly applied nutrients. In this study, nutrient demand functions, which include prices of all three nutrients, are estimated for Tennessee by seemingly unrelated regression. Results suggest that cross-price effects are important in determining plant nutrient demand, at least in the case of Tennessee, and that multicollinearity need not be a hindrance in all cases to including cross-price effects in plant nutrient demand models.

Contract Farming and Its Effect on Small Farmers in Less Developed Countries
Provedor de dados: 31
Autores: Minot,   Nicholas.
It is generally recognized that small-farm agriculture plays a central role in  economic development, both in supplying a significant portion of the domestic food crop supplies  and in generating income for low-income families. For crops such as rubber, tea, coffee, and many  fruits and vegetables, large amounts of labor are required for land preparation, planting,  weeding, harvesting, etc.

Consequences of Deregulation in the Victorian Egg Industry
Provedor de dados: 31
Autores: Alston,   Julian M.
There has been much discussion in recent times of alternative proposals for reform of egg industry regulations. This paper aims to describe, analyse and measure the effects of possible changes to egg industry regulations in Victoria. The conclusion is that there are significant potential net benefits to Victorians from eliminating hen quotas and arrangements for fixing egg prices. The significant losses to each of a small number of producers would be more than offset by the small benefits to each of a large number of consumers. The majority of these net benefits could be obtained, alternatively, by allowing free transferability of quota rather than eliminating quota; but then the benefits would all accrue to quota owners.

FARM LEVEL DEMAND FOR PECANS RECONSIDERED
Provedor de dados: 31
Autores: Wells,   Gary J.; Miller,   Stephen E.; Thompson,   C. Stassen.
Previous studies have consistently indicated the anomalous result of a price inflexible demand for pecans.  However, these efforts did not have an adequate measure of pecan stocks available and, as a result, stocks were either excluded from consideration or a proxy variable was introduced.  A time series of pecan stocks is now available.  Use of this time series in a price dependent demand function results in a flexible farm level demand for pecans.  This points out the danger of excluding an appropriate variable or using a so-called "reasonable" proxy variable.

LEVEL OF STRUCTURAL AGGREGATION AND PREDICTIVE ACCURACY OF MILK SUPPLY RESPONSE ESTIMATES
Provedor de dados: 31
Autores: Smith,   Blair J.; Scott,   Donald R.
Milk supply response was estimated for Pennsylvania using three different levels of structural aggregation.  The base level involved the estimation of milk production in a single equation.  Under the second method, production was the product of two equations: milk per cow and number of milk cows.  The third method factored production into three equations: milk per cow, number of dairy farms, and number of cows per farm.  As expected, the greater the degree of disaggregation the more was learned about the structural aspects of milk production.  At the same time, predictive accuracy generally decreased, but the differences among models was slight.

PLANNING AND EVALUATING AGRICULTURAL RESEARCH IN ZIMBABWE:  A PRELIMINARY ASSESSMENT AND RESEARCH PROPOSAL
Provedor de dados: 31
Autores: Mudimu,   Godfrey D.
Agricultural research has enormous potential for improving Sub-Saharan African countries' agricultural performance, thereby, stimulating agricultural growth and development.  For this potential to be realized, clear policy action is required to accelerate the generation and adoption of new technologies.  This calls for, in the first place, evaluation of past research efforts to expose weaknesses that need to be redressed.  Secondly, if agricultural research is to contribute positively to agricultural development, research resources have to be allocated efficiently among competing research program alternatives.  This requires an informed decision-making tool.  This study examined the evolution and performance of agricultural research in Zimbabwe up to 1980....

Import Elasticity with Government Intervention: A Time Series Cross Section Analysis of Seventy-Two Countries
Provedor de dados: 31
Autores: Roe,   Terry L.; Shane,   Mathew; Vo,   De Huu.
The impact of government intervention on the behavior of a country's import market is investigated by focusing on the departure this intervention induces between excess and import demand functions. A formal model of government behavior is posited where government preferences are embodied in a country's import demand function. This function is related to its corresponding excess demand function through the domestic price to border price transmission elasticity. A pooled cross section data on 72 countries is used to estimate these function for wheat and rice. The results suggest that import demand elasticities are larger than their corresponding excess demand elasticities and that price transmission elasticities are less than unity. Differences in...

AGRICULTURAL PRICE, QUANTITY, AND WELFARE EFFECTS OF AIR QUALITY IMPROVEMENTS
Provedor de dados: 31
Autores: Ribaudo,   Marc; Shortle,   James S.
The failure to allow for significant crop quality effects in a partial-equilibrium model can lead to misleading inferences about the price, output and welfare implications of air quality improvements.  It has been observed that air pollutants such as ozone, sulphur dioxide, and nitrogen dioxide affect the yield and quality of many crops.  The economic benefit from improving air quality in crop producing regions has been measured using a partial-equilibrium approach which accounts only for supply shifting yield effects.  It is shown that a yield-effect only model will underestimate output increases and benefits from an air quality improvement when commodity quality improvements as well as yield increases are forthcoming.

FEEDER CATTLE PRICE DIFFERENTIALS IN ARIZONA AUCTION MARKETS
Provedor de dados: 31
Autores: Faminow,   Merle D.; Gum,   Russell L.
This paper presents the results of an empirical study of price differentials for feeder cattle in Arizona auction markets.  Emphasis is placed upon the estimation of price/weight relationships for steers and heifers.  Estimation of a short-run feeder cattle price differential model resulted in an equation with a good empirical fit.  The model also is in agreement with theoretical expectations.  It is concluded that the model presented in the paper could be maintained and updated periodically to provide a useful supplement to market price information services commonly used by cattle producers.

On Some Aspects of Organizational Efficiency in the Queensland Cattle Slaughtering Industry
Provedor de dados: 31
Autores: Brown,   Colin G.; Drynan,   Ross G.
An examination based on stochastic plant location analysis was made of organizational efficiency in the Queensland cattle slaughtering industry. Short-run models were used to highlight forces influencing commodity flows and plant utilization levels in the industry. These models were also used to explore effects of freight equalization arrangements. Freight equalization was found to involve annual costs of resource misallocation of the order of $1 million. Potential efficiency gains through improved plant locations and sizes were also estimated and found to be at least $4.4 million.

THE EFFECT OF INTERSTATE BANKING ON FARM LENDER MARKET SHARES IN NEW YORK STATE
Provedor de dados: 31
Autores: Carraro,   Kenneth C.; LaDue,   Eddy L.
Commercial bank loans to New York farmers are significantly overestimated in the reported USDA statistics due to out-of-state lending and reporting of some agribusiness loans as agricultural loans by New York State banks.  Correcting for this distortion lowers the 1978-84 average New York agricultural credit market share held by banks from 36 to 24 percent.  As deregulation allows more interstate banking activity, the overestimate of agricultural loan volume in states with money center banks and the corresponding underestimate of loan levels and market shares in nonmoney center states could cause increased distortion of state level farm debt statistics.

FUTURES MARKETS AND FIRM DECISIONS UNDER PRICE, PRODUCTION, AND FINANCIAL UNCERTAINTY
Provedor de dados: 31
Autores: Alexander,   Vickie J.; Musser,   Wesley N.; Mason,   George.
Incorporation of futures markets into the theory of the firm under uncertainty has received considerable attention in risk management. A theoretical model of optimal firm decisions in cash and futures markets considering price, production, and financial risks is presented. Production and marketing strategies for corn and soybeans in Georgia and Illinois are analyzed to determine the optimal amount of futures contracting which may be a hedge or a speculative position. A partial hedge is optimal for most situations for risk averse producers when the amount hedge is variable. With fixed quantity transactions, speculative and cash positions, but not hedging, tend to be E-V efficient.

COMPUTERIZED INDIVIDUAL GRAIN FEEDER CASE STUDIES
Provedor de dados: 31
Autores: Krupp,   Ira J., Jr.
Paper tapes from a computerized concentrate feeding system, "The Executive 8085," were collected from six Michigan farms for three months.  The tapes contained each cow's identification number, the amount of feed programmed, and the amount of feed consumed by each cow.  Cows had actuators on their neck chains which allowed the microprocessor to identify individual cows, limit the feed provided for each animal, and record the feed consumed.  Every twelve hours a new tape was generated for the herd.  Three hypotheses were investigated in this paper.  Hypothesis one:  reduced feed consumption would be correlated with the onset of estrus, as indicated by the feeder.  Hypothesis two:  reduced feed consumption would be correlated with animal diseases, as...

RETURNS TO SCALE AND SIZE IN AGRICULTURAL ECONOMICS

Autores: McClelland,   John W.; Wetzstein,   Michael E.; Musser,   Wesley N.
Differences between the concepts of returns to size and returns to scale are systematically reexamined in this paper.  Specifically, the relationship between returns to scale and size are examined through the use of the envelope theorem.  A major conclusion of the paper is that the level of abstraction in applying a cost function derived from a homothetic technology within a relevant range of the expansion path may not be severe when compared to the theoretical, estimative, and computational advantages of these technologies.

THE VALUE OF PROTEIN IN FEED BARLEY FOR BEEF, DAIRY, AND SWINE FEEDING
Provedor de dados: 31
Autores: LaFrance,   Jeffrey T.; Watts,   Myles J.
The impact of the protein content of feed barley on the costs of feeding beef, dairy cattle, and swine in Montana is evaluated.  A model of least-cost feed rations is constructed to analyze the marginal value of additional protein content in feed barley.  The results indicate that increasing the protein content of feed barley above 12% will not substantially increase the value of barley to feeders.  This implies that the establishment and maintenance of a protein premium in the feed barley market would tend to result in lower average prices for feed barley because the feed value/protein relationship is concave and the market would be sustaining costs that the inherent value of the commodity could not support.

A HOUSEHOLD PRODUCTION ANALYSIS OF FUELWOOD DEMAND IN RHODE ISLAND
Provedor de dados: 31
Autores: MacKenzie,   John; Weaver,   Thomas F.
A model analyzing household substitution of fuelwood for other heating fuels is needed to clarify the relationship between energy prices and patterns of forest resource utilization.  This paper employs the household production methodology to model fuelwood demand in Rhode Island.  Data from a cross-sectional survey of 515 households are employed to test a discrete-choice model of household participation in wood-burning and a four-equation system modeling household production of heat and aesthetic benefits from fuelwood and stove capital.  Control of selection bias via inclusion of an appropriate instrument allows analysis of aggregate demands.  Some broad policy prescriptions applicable to the Northeast generally are presented.

MEASURING THE PRODUCTIVITY OF CAPITAL IN UNITED STATES AGRICULTURE
Provedor de dados: 31
Autores: Gustafson,   Cole R.
The agricultural sector has operated in a period of high real interest rates for over half a decade. Some are concerned that this has limited capital availability and stagnated the historic capital for labor substitution occurring in the sector. This study proposes new procedures for estimating the aggregate production function of United States agriculture. Improvements include incorporation of total returns and revised measures of both durable and nondurable capital inputs. Results indicate increasing capital productivity has occurred, but encouraging further capital substitution may not benefit agricultural producers.

AN ALTERNATIVE APPROACH TO DEFINING AND  ASSESSING POVERTY THRESHOLDS
Provedor de dados: 31
Autores: Blaylock,   James R.; Smallwood,   David M.
This paper introduces a new method for defining poverty lines based on an individual' s self-evaluation of the household's present situation.  The proposed method focuses on the minimum household income necessary to purchase food supplies evaluated by society to be barely adequate.  The method is especially useful for evaluation and comparing poverty thresholds derived from different methods.  It is also valuable for comparing the official U.S. poverty guidelines across households of different sizes.  The approach can be extended to include estimation of thresholds differentiated by various household characteristics and comparison of thresholds across these characteristics.

Provedor de dados: 31
Autores: Izac,   Anne-Marie N.
Chicagoan theories of and policies for unpriced natural resources have gathered momentum over the past twenty years and have reached a fair degree of acceptability among some agricultural economists and some governments. The critical evaluation of the logic, explanatory and predictive power of these theories, which is undertaken in this paper, shows that this acceptability is not well founded. It is demonstrated that these theories embody substantial logical shortcomings and rely on hypotheses which may be falsified. These limitations have important implications for Chicagoan resource policies. Game theory is used to show that Pareto optimality cannot be reached when Chicagoan policies are implemented by a government, contrary to the contention of...

ARE LIVESTOCK FUTURES PRICES RATIONAL FORECASTS?
Provedor de dados: 31
Autores: Shonkwiler,   John Scott.
A measure for evaluating whether live hog and cattle futures prices represent rational forecasts is presented.  It is assumed that the mechanisms which generate rational price forecasts possess the same stochastic properties as the cash prices with which they are associated.  Using empirical data, tests are constructed which suggest that for contracts more than two months from maturity the rationality hypothesis is generally rejected.  These findings are related to other studies of futures performance and the livestock markets.

ECONOMICS OF STONY LAND RECLAMATION FOR CROP PRODUCTION IN SOUTH- WESTERN QUEBEC
Provedor de dados: 31
Autores: Seecharan,   Randolph; Gunjal,   Kisan R.; Millette,   Gerard.
Linear programming model is used to investigate the economic feasibility of utilizing stony lands for crop production in South-Western Quebec where stoniness is the major constraint.  Results for the representative farms indicate that income variations are due to economies of size, differences in crop yields (experimental or farm level) and type of reclamation method used.  The market values for stony lands (determined by regression technique) are higher compared with the productive values.  Analysis also indicates that crop production is feasible within the parameters defined and that it is more economical to develop unutilized stony land rather than purchase prime agricultural land at current market prices.  Parametric programming procedures indicate...

DYNAMIC FACTOR DEMANDS AND ENERGY SUBSTITUTION IN REGIONAL U.S. MANUFACTURING
Provedor de dados: 31
Autores: Vlachou,   Adriana.
Although energy substitution in U.S. manufacturing has been studied in great depth at the national level, little attention has been paid to the regional level.  However, regions may differ in their use of energy for a variety of reasons.  The main objective of this study is to estimate region-specific demands for energy using a dynamic model for two-digit SIC Code manufacturing sectors.  We derive own and cross-price elasticities for energy for different regions and we compare them.  We, thus, provide information which has implications for a region specific energy policy.

A TARGET MOTAD ANALYSIS OF A CROP AND LIVESTOCK FARM IN JEFFERSON COUNTY, FLORIDA
Provedor de dados: 31
Autores: Zimet,   David J.; Spreen,   Thomas H.
An analysis of a typical crop and livestock farm in North Florida is presented. The analysis incorporates the potential competition and complementarity among crop and beef cattle enterprises. A Target MOTAD model is developed to account for risk in a decision framework. The results indicate that when income risk is ignored, peanuts, watermelon, and stocker cattle are the only enterprises included in the optimal solution. When income risk is heavily weighted, the optimal solution includes peanuts, watermelon, stocker cattle, cow-calf, and irrigated soybeans. The results suggest that the persistence of cow-calf production may be explained as a stabilizer of income.

The Effects of Trade and Exchange Rate Policies on Agriculture in Nigeria
Provedor de dados: 31
Autores: Oyejide,   T. Ademola.
The past decade has been one of major turbulence in the global economy, including rapid inflation, oil price shocks, extraordinary rise and decline in food prices, and low real interest rates encouraging borrowers that had later proven unsustainable. The process of managing that turbulence, along with industry-oriented development strategies, has led many developing countries to grossly overvalue their exchange rates. The extent to which overvaluation discriminates against exports and agriculture in general and agricultural exports in particular had received increasing emphasis in recent years. Thus, the International Food Trade and Food Security Program at IFPRI has undertaken a series of country studies on the foreign trade and exchange rate regimes as...

A multiperiod programming model was used to simulate the effects of lower marginal income tax rates, the soil and water conservation deduction, and the cash tax accounting option on firm growth for a "representative" farm operating in the Alabama Black Belt region. Results show the lowered marginal income tax rates associated with the Economic Recovery Tax Act (ERTA) of 1981 provide a positive growth stimulus to the modeled firm as measured by accumulated net worth over a 10-year planning horizon. The soil and water conservation deduction in general provides greater tax relief to the modeled firm than either the ERTA income tax rate changes or the cash tax accounting provision. Important complementary and substitute relationships were found to exist...

A DYNAMIC ANALYSIS OF OPTIMAL WATER USE UNDER SALINE CONDITIONS
Provedor de dados: 31
Autores: Knapp,   Keith C.; Dinar,   Ariel.
Irrigation with saline waters is a major problem in many parts of the world.  Economic questions have usually been addressed using synthesized production functions and theoretically based soil salinity relations.  The purpose of this paper is to estimate functions relating crop yield and salt accumulation in the soil to initial soil salinity and water quantity and quality.  Crop response functions and dynamic salt balance relations are estimated from experimental data for alfalfa and cotton.  The estimated functions are then used in a dynamic programming model to determine optimal water applications for different levels of initial soil salinity and crop and water prices.

Social aspects of water management during the Maha season 1985/86 in Dewahuwa and Mahaweli H-2 Block 305: precept and practice
Provedor de dados: 31
Autores: Bulankulame,   Senarath.
The International Irrigation Management Institute (IIMI) began research projects in Dewahuwa Tank and Mahaweli 11-2 during the Yala season (May-Aug.) of 1985. The research focussed initially on agricultural economics (e.g., farmers' use of agricultural inputs and returns from different crops) and on irrigation engineering (water distribution and flow rates). In the second season (Maha 1985/86) of research a social science component was added to address issues of farmers' management decisions and the institutional arrangements by which farmers and agency officials operate and maintain the irrigation works. This report summarizes the research results of the social science component for the Maha season, from October 1985 to April 1986.

RISK ATTITUDES AND FARM/PRODUCER ATTRIBUTES: A CASE STUDY OF TEXAS COASTAL BEND GRAIN SORGHUM PRODUCERS
Provedor de dados: 31
Autores: Ramaratnam,   S. Sri; Rister,   M. Edward; Bessler,   David A.; Novak,   James L.
An analysis of risk attitudes for a sample of grain sorghum producers in the Texas Coastal Bend is reported. Four alternative functional forms were estimated on data elicited by the direct elicitation of utility approach. The exponential functional form described most producers' utility preferences better than other utility forms. Relationships between exponential risk measures and both producer attributes and farm characteristics, including interactions among them, were identified as significant. Risk aversion was found to diminish with more experience in farming and to increase with more leasing of farm land. Risk aversion was also found to decline with larger farm size and to increase with higher dependency of farm operators on farm income.

PLANT LOCATION ANALYSIS USING DISCRETE STOCHASTIC PROGRAMMING
Provedor de dados: 31
Autores: Brown,   Colin G.; Drynan,   Ross G.
A plant location model with two major aspects is outlined. First, discrete stochastic programming is used to handle variability in supplies and demands. Second, the cost structure of plants is modelled in more detail and with more realism than is usual. Results from applying the model to the Queensland cattle slaughtering industry demonstrate the inappropriateness of using traditional deterministic plant location models to analyse problems with major stochastic elements. Deterministic models yield plant locations, sizes, throughputs, commodity flows and implications which differ markedly from those generated by stochastic models in which plant sizes and locations are optimally matched to variable fat cattle supplies. In addition, the traditional...

Provedor de dados: 31
Autores: Kennedy,   John O.S.
A method of deriving rules for optimal fertilizer application when there is carryover is presented. The carryover situations considered are: carryover a deterministic function of fertilizer available in the previous period; carryover a deterministic function of fertilizer applied in more than one previous period; and carryover a stochastic function of fertilizer available in the previous period. The method of derivation is more direct than an inductive one previously presented. The rules are given an economic interpretation, and the gains from using them in practice are considered.

A daily limitation on the number of hours irrigators can pump may be imposed by utility companies seeking to use the company's generating capacity more efficiently.  Three power interruption patterns are analyzed to determine electricity cost reductions which would have to be offered to keep irrigators from being made worse off by the interruptions.  Irrigation system pumping capacity and the irrigator's attitudes toward risk are found to be primary determinants of the size of the required reductions.

Autores: Gray,   Thomas W.
This paper applies concepts of member sovereignty (capability of people to create and effect decisions on how a system should operate and change) and equality (even distribution of articulation possibilities among members) to large agricultural cooperatives. Equality is reconceptualized to refer to elected member representativeness in large cooperatives. An elite interviewing technique was used to gather descriptions of control structures and mechanisms in five Western European countries. Interviews were conducted with decision makers in apex cooperative education organizations. Hierarchal membership structures are described, weaknesses are pointed out, and options to improve member sovereignty and elected member representativeness are discussed.

FORWARD CONTRACTING VERSUS HEDGING UNDER PRICE AND YIELD UNCERTAINTY
Provedor de dados: 31
Autores: Miller,   Stephen E.
Although apparently preferred by farmers to direct hedging as a forward pricing mechanism, forward contracting has received little attention in the literature dealing with optimal forward pricing levels. An often-cited reason for producer preference for forward contracting is the absence of basis risks under that forward pricing alternative. This paper presents models of optimal forward contracting and hedging under price and yield uncertainty within a mean-variance framework. The results indicate that basis certainty does not explain preferences for forward contracting.

WHAT DOES MANUFACTURING PROTECTION COST FARMERS? A REVIEW OF SOME RECENT AUSTRALIAN CONTRIBUTIONS
Provedor de dados: 31
Autores: Parmenter,   B.R.
A method proposed by Clements and Sjaastad for measuring the effect of manufacturing protection on farmers' incomes is shown to be theoretically unsound, to use some inappropriate assumptions and to lead to overestimation. Even if corrected, the method seems inferior to estimating directly via ORANI the change in farm incomes which would occur when protection levels change. This is because the model contains detailed theoretical explanations of the price and quantity changes which determine changes in the relevant incomes and is calibrated using extensive empirical evidence about the behaviour of the prices and quantities in the Australian economy. Using ORANI and incorporating recently completed improvements to its agricultural data base, it is estimated...

Fundamentals of Price Analysis in Developing Countries' Food Systems: A Training Manual to Accompany the Microcomputer Software Program 'MSTAT'
Provedor de dados: 31
Autores: Goetz,   Stephan J.; Weber,   Michael T.
In market-oriented economies, agricultural markets and marketing  functions become increasingly important as the food system evolves. This paper  focuses on how selected dimensions of markets and marketing functions can be  studied and evaluated in Third World settings.  The specific purpose of this  paper is to review fundamental price and related market analysis techniques  which are and can be used in developing country food system applications. In so  doing the objective is also to focus on identifying food system problems,  techniques for improved interpretation of price analysis results and means of  dealing with the all too common problem of data limitations. A second purpose  of this paper is to serve as a "Training Manual" to accompany "MSTAT."

COMMODITY AND CONSERVATION POLICY IMPACTS ON RISK AND RETURNS
Provedor de dados: 31
Autores: Hoag,   Dana L.; Young,   Douglas L.
Crop yields, farm income risk and returns, and soil losses were simulated from 1974 to 1984 for southeastern Washington Palouse-region farms in three climatic subregions under alternative conservation and commodity policy scenarios.  Historical commodity programs reinforced preexisting disincentives to retire highly erodible land to perennial grasses, but cropland base protection (CBP) legislation would eliminate such disincentives and increase profitability and decrease risk of land retirement.  Nevertheless, additional incentives would be needed.  Government rental payments can provide necessary incentives, but they are more costly without CBP. CBP was not included in the 1985 farm bill.

PERFORMANCE OF RISK-INCOME MODELS OUTSIDE THE ORIGINAL DATA SET
Provedor de dados: 31
Autores: Atwood,   Joseph A.; Held,   Larry J.; Helmers,   Glenn A.; Watts,   Myles J.
Selected risk programming solutions (i.e., profit maximization, Target-MOTAD, and MOTAD) are tested in an economic environment outside the data set from which they were developed. Specifically, solutions are derived from either a longer 10-year (1965-74) or shorter 6-year estimation period (1969-74), and then, they are tested for consistent risk-income characteristics over a later 10-year period (1975-84). Risk solutions estimated from earlier periods perform well in the later test period in spite of different economic conditions between time periods. However, favorable performance may be related to the specific example used in this analysis. Further testing for other farm situations is needed before general conclusions can be reached.

Risk aversion in a dynamic trading game
Provedor de dados: 31
Autores: Karp,   Larry S.
The effect of risk aversion on Nash equilibrium trade restrictions is studied using numerical methods. An increase in a nation's level of risk aversion can lead to either an increase or decrease in its equilibrium restriction and either an increase or decrease in its rival's restriction. The linear quadratic dynamic game is generalized to include risk aversion.

A Note on Victoria's Hen Quota Transfer System
Provedor de dados: 31
Autores: Alston,   Julian M.
Hen quotas were virtually freely transferable within Victoria when they were first introduced in 1975. The 1980's have witnessed a series of changes to regulations over quota transfers. Initially these changes were components of a plan to phase out quotas but that is no longer on the policy agenda. Quotas remain but without the advantages of free transferability.  It is well established that restrictions on quota transfers in general lead to production inefficiencies. Another undesirable side-effect is that the value of quota and magnitude of quota rent are more difficult to measure when quota transfers are restricted, adding to the difficulties of assessing the effects of the regulations. In the Victorian egg industry these general problems are confounded...

THE USE OF DISCRIMINANT ANALYSIS IN MEASURING COOPERATIVE GROWTH FACTORS
Provedor de dados: 31
Autores: Henehan,   Brian M.; Pelsue,   Neil H., Jr.
Vermont agricultural cooperatives were surveyed to investigate key factors contributing to cooperative success.  Most of the cooperatives were formed within the last 15 years.  Financial, organizational, and operational data were collected for selected years from 1974-1984.   Average annual changes in gross sales were used to divide cooperatives into low-growth and high-growth groups.  Selected variables were identified to classify individual cooperatives into low- or high-performance groups with discriminant analysis.   Management experience and adoption of multi-year plans were the two factors found to have the most significant influence on cooperative sales growth.

ECONOMIC ANALYSIS OF ON-FARM AGRONOMIC DATA USING A MICROCOMPUTER:  APPLICATIONS TO THE ADAPTIVE RESEARCH PROGRAM IN MALAWI
Provedor de dados: 31
Autores: Phiri,   Benson Samuel.
The Department of Agricultural Research (DAR) in Malawi has made a modest contribution to small farmers in supplying them with recommendations they can adopt.  This was largely due to the biological emphasis of the department. In order to introduce social scientists and following in recognition of the poor adoption of recommended technology, Farming System Research (FSR) was introduced in 1979.  That has now changed to Adaptive Research.  This also followed a major reorganization of the department into Commodity and Adaptive Research Teams. Biological scientists rely on analysis of variance in evaluating alternative technologies and while it is useful in determining the significant differences among treatment means, it is not sufficient for making...

In 1977, IFPRI published Research Report 3, Food Needs of Developing Countries: Projections of Production and Consumption to 1990, which presented an assessment of the current and prospective food situation of developing market economies. The study covered major food crops (cereals, roots and timbers, pluses, and groundnuts) in 82 countries and used 10960-75 data on cereals from USDA and noncereals from the FAO. It made trend-bases projections of food production and consumption into the future, which pointed to a possible gross deficit of 120-145 million metric tons by the end of the current decade. The report also called attention to the special food problem of the low income countries in Asia and Sub-Saharan African “Whose major option is to increase...

THE ECONOMIC IMPACT OF BGH ON THE NEW YORK STATE DAIRY SECTOR: COMPARATIVE STATIC RESULTS
Provedor de dados: 31
Autores: Magrath,   William B.; Tauer,   Loren W.
The price and quantity effects of a forthcoming biotechnology product, bovine growth hormone (bGH), are explored in a simple partial equilibrium model.  The model is based on previous theoretical work on technological change but is developed in terms of a sector output.  A particular output curve is estimated using data from a random sample of New York State dairy farms.  Information on the farm level production effects of bGH is used to shift the output curve and to solve for equilibrium levels of price and output.  The model projects the bGH may lead to the exit of 5,400 New York dairy farms and a 20 percent reduction in herd size.  Consumers will benefit from an approximately 30 percent drop in milk price.  The effect on gradual diffusion of bGH on farm...

U.S. Consumer Behavior over the Postwar Period: An Almost Ideal Demand System Analysis
Provedor de dados: 31
Autores: Blanciforti,   Laura Ann; Green,   Richard D.; King,   Gordon A.
This study analyzes U.S. consumer budget allocations among 11 aggregate commodity groups for the period 1948-78.  Also budget allocations among four food groups are analyzed for this same period.  Several alternative model specifications are analyzed. Emphasis is given to the Deaton-Muellbauer (1980a) "almost ideal demand system." A dynamic version of their model is developed and quantified.  Comparison of the static and dynamic formulations are compared with similar specifications for the "linear expenditure system." The predictive performance of these four models for the 11 commodity groups is tested for the sample period (1948-78) and for the years 1979-81.  The purpose of this study was to develop improved methods for analyzing demand relationships for...

PRICE SUPPORTS AND EXCHANGE RATE ADJUSTMENTS; IMPLICATIONS FOR JAPANESE WHEAT AND BEEF MARKETS, 1960-83
Provedor de dados: 31
Autores: Inomata,   Norio.
An agricultural protection policy is very common among industrial countries.  However, there are actual pro and con arguments for it because someone must bear its cost.  Even in Japan, consumers themselves do not necessarily object to increasing the importation of agricultural products.  It may not be easy for today's advanced industrial countries to determine the criteria for opening their agricultural markets completely since to implement this kind of policy adjustment, many difficult political considerations must be taken into account. The number of agricultural items restricted for import in Japan was reserved at 22, in 1983.  This number was the greatest among the advanced industrial countries.  According to the investigation by Yujiro Hayami, the...

THE MISSING INCOME PROBLEM IN THE ANALYSES OF ENGEL FUNCTIONS
Provedor de dados: 31
Autores: Capps,   Oral, Jr.; Cheng,   Hsiang-Tai.
The empirical evidence from the extant literature in demand analysis points to the importance of income in food expenditure relationships.  However, roughly 30 percent of all households in the 1977-78 Nationwide Food Consumption Survey do not report income figures.  The focus of this paper is on the missing income problem in analyses of Engel functions.  This analysis statistically links particular demographic attributes in affecting the probability of reporting income information.  Additionally, several techniques to overcome the missing income problem, namely, regression imputation, the Heckman procedure, and item deletion, are discussed.  Empirical evidence suggests that the Heckman procedure is statistically superior to item deletion, and that...

TESTING FOR CHANGES IN THE PRICE ELASTICITY OF RESIDENTIAL ELECTRICITY DEMAND
Provedor de dados: 31
Autores: Stevens,   Thomas H.; Adams,   Gail.
The demand for electricity in the residential sector is estimated to have become less elastic for the recent period of rising real prices as compared to earlier periods of stable or falling real price.  Several possible reasons for this are investigated and we conclude that demand appears to be asymmetric with respect to price in both the short and long run.  We then examine whether or not this is an important factor for forecast accuracy and public policy.

WHEAT IMPORTS AND CHEAP FOOD POLICY IN KOREA
Provedor de dados: 31
Autores: Son,   Jeong Soo.
In September 1983, the Korean government changed the wheat policy towards import dependence by lifting all support systems for domestic wheat production.  The transformation of the wheat policy is basically grounded in the comparative advantage which emphasizes the cheap food policy with the assumption that food prices are an essential component of wage decisions, therefore a high level of food prices cause the rise in wages of the urban workers and reduces economic growth.  To justify the cheap food policy, at least it should be proved to be true that the policy direction is beneficial to the overall economy.  In this context, the focus of this study is centered on the effects of wheat imports on domestic production, and the contribution of cheap food...

THE TRAVEL COST DEMAND MODEL AS AN ENVIRONMENTAL POLICY ASSESSMENT TOOL:  A REVIEW OF LITERATURE
Provedor de dados: 31
Autores: Ward,   Frank A.; Loomis,   John B.
Estimates of the benefits of environmental improvement, usually a nonmarket commodity, can be a valuable part of the information base for economically efficient environmental decision making.  The objective of this paper is to review the literature of one class of nonmarket valuation methodologies based on observed consumption behavior subsumed under the term "travel cost demand models."  Relative to travel cost demand models, we examine policy issues and underlying concepts focusing on choice theory and welfare evaluation.  In addition, we identify major related empirical issues including demand specification, data problems, demand estimation, and welfare measurement.  Unanswered questions may contribute to a research agenda.

EFFICIENCY AND EQUITY:  A STRUCTURAL PERSPECTIVE
Provedor de dados: 31
Autores: Kelsey,   Timothy W.
Economists evaluating policies frequently split the measurement of effects into two elements:  efficiency, and the distribution of income.  Traditional economic theory has focused primarily upon efficiency, under the assumption that efficiency alone avoids subjective judgments.  Considerations of distribution, based on equity and involving subjectivity, are eschewed because of their normative nature. Efficiency is regarded as an objective function, as a mere description of observable reality which can be scientifically tested.  It is perceived as existing in and of itself, unaffected by subjective sensibilities.  Equity, in contrast, "has to do with justified or justifiable distributions of rights and privileges among people.  An equitable distribution...

A BAYESIAN FRAMEWORK FOR OPTIMAL INPUT ALLOCATION WITH AN UNCERTAIN STOCHASTIC PRODUCTION FUNCTION
Provedor de dados: 31
Autores: Griffiths,   William E.
A Bayesian approach is used to provide a framework for optimal input allocation for a stochastic production function with uncertain parameters. The chosen production function is a single-input version of a function which can exhibit positive or negative marginal risk. The sensitivity of optimal input allocation to the degree of risk aversion, the marginal risk parameter, and the assumed level of uncertainty about the parameters is examined. Using an example problem it is shown that parameter uncertainty will not always lead to a lower input level when a producer is risk averse. Some problems with the production function specification are uncovered, as is the incompatibility of some expected utility and stochastic assumptions.

This study presents the empirical results of estimating the household broiler meat expenditure pattern in the western region using the 1977-78 United States Department of Agriculture Nationwide Food Consumption Survey.  The effects of assuming homoscedasticity and heteroscedasticity in the tobit model on resulting estimates are discussed in terms of estimated coefficients, marginal effects, and elasticities.  Based on the strength of the sample data, the results suggest that specification of the homoscedastic model should be rejected in favor of the heteroscedastic model, implying that the validity of homoscedasticity should not be routinely accepted without testing when applying tobit procedure to analyze survey data.

Autores: Throsby,   C.D.
This paper traces the perceptions of the agricultural sector held by economists over the last three centuries, with particular emphasis on how the evolution of these ideas has influenced the state of present-day thinking about the economic role of agriculture in developed and developing economies. The paper begins with the seventeenth and eighteenth centuries, leading to a consideration of the place of agriculture in the work of the major figures of classical political economy from Adam Smith to Marx. The rise of neo-classical economics, and its influence on twentieth century thinking, is discussed. In the contemporary period, particular attention is paid to agriculture in development theory, with an assessment of conflicting theoretical ideas about the...

ETHICAL PREFERENCES AND THE ASSESSMENT OF EXISTENCE VALUES: DOES THE NEOCLASSICAL MODEL FIT?
Provedor de dados: 31
Autores: Edwards,   Steven F.
Some of the implications of ethical preferences for traditional welfare analyses of existence values are discussed in this paper and illustrated with a lexicographic model for preference structures.  Although willingness-to-pay and willingness-to-sell are well-defined, their connection with Hicksian surpluses is lost when a person is motivated by an ethical commitment to others welfare.  Researchers need to expand contingent valuation methods to collect information on underlying motives and types of preferences in order to identify respondents who fit the neoclassical model of egoistic man.

Autores: Soler,   Alvaro; Fuller,   Earl I.
This study reports on how different microcomputer systems performed in the solution of two linear programming models purposely specified with redundant vectors.  Comparisons were made to a Cyber 720 that used both a Fortran and Basic version of the same primal-dual algorithm.  Results are mixed.  But Microsoft Basic with double precision under CP/M on a Z80A processor performed at least equally well to the Cyber 720 provided that an appropriate essential zero value was specified.  Different coefficient scaling schemes were also tested.  The results should be of interest to all users of matrix inversion schemes on microcomputers.  Extensions of the study to new hardware and software systems are encouraged.

MODELING THE DEMAND FOR DURABLE INPUTS: DISTRIBUTED LAGS AND CAUSALITY
Provedor de dados: 31
Autores: Mui,   H.W.; Bradford,   Garnett L.; Ali,   Mukhtar M.
Vector-autoregressive-moving-average (VARMA) modeling was used to identify distributed lag relationships among farm tractor derived demand variables and to provide a basis for formally testing the hypothesis that the price of new tractor horsepower is exogeneous to its quantity demanded. Similar causality tests were used for a number of other explanatory variables, including the interest rate, price of diesel fuel, and price of used tractors. Results indicate that several lagged variables are significant causal factors and that the dynamic nature of the demand structure cannot be ignored when explaining tractor demand.

AN ASSESSMENT OF HAY MARKET INSTITUTIONS AND COORDINATION FUNCTIONS
Provedor de dados: 31
Autores: Miller,   Jeffrey H.
The experience of Michigan farmers illustrates the dilemma faced by hay growers:  while hay production has received a great deal of attention, hay marketing has been neglected.  Supplies of high quality hay can be expanded within the span of a single growing season, but the marketing system generates prices which do not always clear the market and which do not serve as accurate signals to guide planning decisions.  More fundamentally, there are no effective market mechanisms to generate those prices, to match buyers and sellers, or to move hay cheaply from surplus to deficit regions.  Clearly, this is not because hay is a minor crop.  In Michigan, hay is the second largest crop grown on a per acre basis.  Apart from the direct economic value of hay, it has...

Risk, Implicit Contracts and the Family in Rural Areas of Low-Income Countries
Provedor de dados: 31
Autores: Rosenzweig,   Mark R.
In this paper the role of family structure in mitigating income volatility in the absence of income insurance in low-income agricultural environments is discussed. Hypotheses concerning the relationship between the membership, size and composition of households and insurance-based income transfers are tested using longitudinal data from India. A test is also performed of whether a household's ability to reduce risk ex post via family arrangements affects its willingness tobear risk ex ante through its selection of formal tenancy contracts. The results support these hypotheses concerning the risk-mitigating roles of both household structure and share contracts, and indicate as well the importance of heterogeneity in risk-aversion across households.

Rapid Reconnaissance Guidelines for Agricultural Marketing and Food System Research in Developing Countries
Provedor de dados: 31
Autores: Holtzman,   John S.
This paper develops rapid reconnaissance guidelines for conducting research on  agricultural marketing components of food systems. A rapid reconnaissance survey is a broad and  preliminary overview of the organization, operation and performance of a food system or  components therefore, designed to identify system constraints and opportunities. It can be used  as a tool for identifying system dynamics, linkages and overall problems, which can then be  examined more intensely during follow-up programs of research.

PROMOTION OF PRIMARY PRODUCTS - A VIEW FROM THE CLOISTER
Provedor de dados: 31
Autores: Quilkey,   John J.
This paper is a discourse on how promotion may contribute to the efficiency of consumption. The view is taken that, through its addition to the quantity of search with respect to product characteristics, promotion may enable consumers to allocate their expenditures more efficiently and yield additional revenue to producers of the promoted product. The central plea is for consistency in the identification of promotion objectives, the implementation of the promotion program and monitoring of the outcome. In an idiosyncratic way, the promotion objectives are framed as being related to price and income elasticities and it is argued that promotional outcomes should be monitored in terms of these elasticities. Supply shifts may complement promotion strategies to...

THE DEMAND FOR FRUIT JUICES:  MARKET PARTICIPATION AND QUANTITY DEMANDED
Provedor de dados: 31
Autores: Brown,   Mark G.
The quantity demanded in a market can be decomposed into two components: the number of purchasers and the quantity per purchaser.  Focusing on these two components, the demands for different types of single-flavor fruit juice commodities are analyzed.  The approach allows the market demand elasticities to be estimated as the sum of elasticity estimates for the numbers of purchasers and the elasticity estimates for the quantities per purchaser.  The method of seemingly unrelated regressions is employed to estimate the equations for the two demand components for the different types of juice.

FINANCIAL RISK MANAGEMENT ALTERNATIVES IN A WHOLE-FARM SETTING
Provedor de dados: 31
Autores: Pederson,   Glenn D.; Bertelsen,   Diane.
Risk programming and simulation methods are used to analyze the opportunity to reduce whole-farm risk in a diversified cash crop farm through reduced leverage and/or adjustments in rental arrangements.  These two financial strategies are shown to extend the ability of the farm operator to manage downside risk beyond the singular effects of a diversified farm plan.  The analysis indicates that a trade-off occurs between these strategies, but that the reduction of debt has a greater impact on the distributions of net cash flow (before taxes) and outstanding term debt.

SUCCESSFUL DAIRY FARM MANAGEMENT STRATEGIES INDENTIFIED BY STOCHASTIC DOMINANCE ANALYSES OF FARM RECORDS
Provedor de dados: 31
Autores: Kauffman,   Jonas B. III; Tauer,   Loren W.
First-degree and second-degree stochastic dominance were used to separate a panel of 112 dairy farms with ten annual observations per farm into successful and less successful groups using four different performance measures.  Logit regression using 16 independent variables was then used to determine important farm characteristics leading to farm success.  High milk production and controlling hired labor and purchased feed expenses were important.  The selective adoption of new technologies was also important.  Optimal debt-asset ratios varied over the 10-year period.

DEPARTMENT VALUES IN THE PURSUIT OF EXCELLENCE

Autores: Connor,   Larry J.
Any academic department should place a high value on excellence. Regardless of the area or nature of the department, the age of the faculty, availability of funds, or particular administrator, excellence should be the paramount pursuit of all faculty. It is necessary to distinguish between individual and departmental excellence. Both are important. However, departmental excellence is more than merely the aggregation of program excellence of individual faculty. There is a considerable difference between "a community of scholars" and a "collection of individual scholars."

Provedor de dados: 31
Autores: Burton,   Robert O., Jr.; Wollo,   J. Wesseh.
A dynamic (multi-period) linear programming model of a beef/sheep farm was used to evaluate the potential for increasing income and for maintaining a specified level of annual income during a cattle cycle.  Results indicate that both objectives may be accomplished by adjusting animal numbers in response to changing price ratios: a higher proportion of cows should be kept during the accumulation phase of the cattle cycle, and a higher proportion of ewes should be kept during the liquidation phase.

DYNAMICS OF HERD BUILD-UP IN A NEW INDUSTRY:  COMMERCIAL RED DEER PRODUCTION IN NEW ZEALAND
Provedor de dados: 31
Autores: Sandrey,   Ronald A.; Zwart,   A.C.
A mathematical decision model is used to examine producers' decisions in selecting the optimum slaughter age for domestic deer and the subsequent impact of these decisions on aggregate stock numbers.  Under current returns from velvet, producers are shown to be rational in keeping both male (stags) and female (hinds) animals in the herd until they approach their maximum biological age.  A reduction in returns from velvet of 66% is needed to alter this age significantly for males.  Data from the optimum slaughter age decision are used to project medium-term future venison production and herd numbers.  The unique features of attempting to project future supplies in a newly developed livestock industry are discussed.

A MIXED-INTEGER PROGRAMMING ANALYSIS OF THE STRUCTURE OF A FLORIDA-BASED CATTLE FEEDING INDUSTRY
Provedor de dados: 31
Autores: Spreen,   Thomas H.; Moseley,   Anne E.; Pheasant,   Jim W.
Florida is typical of many southeastern states in that it exports feeder cattle and imports carcass and boxed beef. The objective of this paper is to estimate the cost of retaining feeder cattle in Florida, feeding these cattle to slaughter weights, slaughtering them, and distributing the meat to retail outlets. A mixed integer programming model is developed. The optimal number and location of feedlots and slaughter plants are determined. The results indicate that at production levels exceeding 600,000 head, the cost of producing carcass beef in the State is comparable to the average for the United States.

This paper presents a conceptual framework, known as systems development, for designing, selecting, and evaluating information systems. Techniques are developed that aid farm managers in choosing an accounting system. Six farmers took part in case studies testing the selection techniques. The participating farmers exhibited great diversity in the preferred design of their accounting systems and the manner in which they desired reports to be presented. This diversity suggests that system selection is an important aspect of implementing an accounting system.

Increased consumer health concerns over ingestion of animal fats have spawned consumer research regarding effects of different degrees of leanness (marbling levels) on consumer demand.  Previous research is reviewed and a recent multi-city consumer panel test is reported.  Implications of the multi-city results are discussed from the viewpoint of applicability of normative consumer behavior demand theory, and implications of the findings for beef marketing structure and strategies.  Suggestions for consumer panel research designs are also implied.  Expert laboratory, consumer laboratory, and household panels were employed.

A MULTI-PRODUCT ANALYSIS OF ENERGY DEMAND IN AGRICULTURAL SUBSECTORS
Provedor de dados: 31
Autores: Adelaja,   Adesoji O.; Hoque,   Anwarul.
A multi-product cost function model was used to analyze energy demand in various agricultural subsectors. This approach has advantages over previously used approaches since it reduces aggregation bias, considers technological jointness, and provides various disaggregative measures related to energy input demand. When fitted to West Virginia county level data, labor and miscellaneous inputs in crop and livestock production were found to be substitutes for energy, while capital, machinery, and fertilizer were complementary to energy. Energy demand was inelastic and increases in machinery prices had the largest reduction effect on energy demand. Technological change was found to be capital, machinery, and fertilizer using, but it was labor and energy saving....

Composition of North Dakota's Economic Base: A Regional Analysis
Provedor de dados: 31
Autores: Coon,   Randal C.; Leistritz,   F. Larry; Hertsgaard,   Thor A.
The economic base of North Dakota and its eight substate regions has changed over the past couple of decades. This report takes an in-depth look at the economic base for each of these areas over the 1958-1984 period. Each of the regions has a unique composition of basic activities that have been responsible for its growth. Natural resource related activities, either in the form of agricultural or energy production, have been the largest source of real economic growth within the state. The purpose of this report is to identify the components of the economic base at substate levels and to show the changes in relative composition for these activities. Price and production data are presented to support and explain the changes that have occurred.

AN INVESTIGATION OF THE RELATIONSHIP BETWEEN CONSTRAINT OMISSION AND RISK AVERSION IN FIRM RISK PROGRAMMNG MODELS
Provedor de dados: 31
Autores: Musser,   Wesley N.; McCarl,   Bruce A.; Smith,   G. Scott.
A model with omitted resource constraints is suggested as an alternative to a risk aversion model for explaining economic behavior. This paper uses two standard mathematical programming models to further explore this issue. One model is a standard profit maximization linear programming model and the other is a risk averse quadratic programming model with part of the constraints deleted. Theoretical investigation of these models demonstrates that risk aversion can substitute for omitted resource constraints. A small empirical model is then solved under both formulations. With resource constraints deleted, positive risk aversion is necessary to obtain a similar enterprise organization as under profit maximization with complete constraints. These two...

INTERPRETATIONS AND TRANSFORMATIONS OF SCALE FOR THE PRATT-ARROW ABSOLUTE RISK AVERSION COEFFICIENT:  IMPLICATIONS FOR GENERALIZED STOCHASTIC DOMINANCE
Provedor de dados: 31
Autores: Raskin,   Rob; Cochran,   Mark J.
The Pratt-Arrow measure of absolute risk aversion, as defined by r(x)=-un(x)/u1(x), is well known to be invariant to linear transformations.  However, this invariance property applies with respect to transformations of u and not with respect to arbitrary rescalings of the outcome variables, x.  The effects of this misunderstanding has led to ambiguity in classifying attitudes by risk aversion coefficients.  It is shown that inappropriate rescalings of the outcome variable can lead to inaccurate rankings produced by generalized stochastic dominance.

Success in ensuring a continuous, adequate supply of food is one of the most important bases on which governments of low-income countries are judged by their people. This is because downward fluctuations in food supplies wreak great privation on low-income people and redistribute real income away from them. In view of this, the International Food Trade and Food Security Program at the International Food Policy Research Institute (IFPRI) has undertaken a series of studies of food supply management in developing countries. Among the policies considered have been schemes to compensate for fluctuations in food production and supply and in foreign exchange availability at the national, regional, and international levels. IFPRI's studies of food management...

The effect of real exchange rates, real price, and demand factors on the exports of each commodity is examined to test the hypothesis that monetary factors can affect the agricultural sector. An examination of the elasticities of real price, real exchange rate, and real income indicate that an extremely inelastic response to both price movements and exchange rate adjustments. Foreign buying power is the strongest explanatory variable. An exchange rate linkage with the agricultural sector is not proven.

ACREAGE PLANTING DECISION ANALYSIS OF SOUTH CAROLINA TOMATOES: NERLOVIAN VERSUS JUST RISK MODEL
Provedor de dados: 31
Autores: Fu,   Tsu-Tan; Fletcher,   Stanley M.; Epperson,   James E.
Factors which explain supply response behavior of South Carolina tomato growers were determined. Two well known supply response models were used for comparison: the Nerlovian structural model and the Just risk model. The Just risk model reflected the significance of the risk effect in both stable and unstable periods. An evaluation of forecasting power between the two models was indeterminate. Growers are apparently willing to invest in more information with increased market instability because growers were influenced by the Florida winter price of tomatoes in planting decisions during the period of instability.

FINANCIAL ANALYSIS OF ON-FARM GRAIN DRYING
Provedor de dados: 31
Autores: Kiker,   Clyde F.; Lieblich,   Mark S.
Artificial drying of corn in the Southeastern Coastal Plain was shown to be financially feasible for average annual per farm production levels of greater than 10,000 bushels. Net present values for four types of drying systems were evaluated using simulation modeling in which weather conditions, yield levels, and prices were entered as stochastic variables. Scale of production and irrigation substantially influenced crop drying potential. Stochastic efficiency analysis was used to evaluate the riskiness of the investment.

COMMON PROPERTY, PRIVATE PROPERTY AND REGULATION THE CASE OF DRYLAND SALINITY
Provedor de dados: 31
Autores: Quiggin,   John C.
The term 'common property' has frequently been misapplied to situations where no property rights exist. Common property rights have provided a workable alternative to private property in many historical situations. Common property concepts and institutions can also play a major role in analysing and responding to current environmental problems. In this paper, the problem of dryland salinity is examined and solutions based on common property, private property and regulation are compared.

THE IMPACT OF A NEW GRADING SYSTEM ON THE BEEF CATTLE INDUSTRY:  THE CASE OF CANADA
Provedor de dados: 31
Autores: Considine,   Jennifer I.; Kerr,   William A.; Smith,   Gregory R.; Ulmer,   S. Monica.
Changes in the grading systems of agricultural commodities will lead to considerable adjustment costs. In 1972 Canada introduced a change in its grading system for beef.  The period of adjustment for beef producers has been in excess of ten years.  The observed pattern of adjustment for one of Canada's cattle-producing areas is discussed and the costs associated with the adjustment process estimated.  Some measures to reduce the costs of adjustment are outlined.

Uso de redes de espera no estudo de ritmos circadianos de algumas espécies de peixes nos lagos de várzea do rio Solimões
Provedor de dados: 104
Autores: Barthem,Ronaldo Borge.
Rhythmic activity patterns are demonstrated for 15 species of fish in várzea lakes of the Solimões river by analyzing catch per hour-of-day data. Supplemented by visual observation, an array of six gillnets of equal length but different mesh size was used for collecting. The data, in general, show a bimodal pattern of activity. The two peaks of catch can be related to movement during twilight periods, while low catches can be ascribed to reduced activity during times close to mid-day or night Observed activity peaks correspond to local displacements of fish between feeding and shelter sites. In the case of piscivorous fishes, activity peaks could be explained by facility in prey localization, which is greatest during twilight periods when prey species are...

Microscopia óptica e eletrônica do corpúsculo de Stannius do curimbatá (Prochilodus scrofa Steindachner, 1881) (Osteichthyes, Cypriniformes, Prochilodontidae)
Provedor de dados: 104
Autores: Pinheiro,Elza Ferreira Goldman; Alexandrino,Agar Costa; Ferri,Silvio.
The Stannius corpuscles of Prochilodus scrofa are studied microscopically (both optically and electronically) as well as macroscopically. Two CS, and sometimes 3 or 4, are found per animal. They are pink-coloured organs, rounded in shape and scattered laterally in the first anterior third of the kidney. Each CS is enveloped by a thick connective tissue capsule. The grandular parenchyma consists of only one cellular (PAS-/AF-) type, cylindrical in shape, with oval or rounded nucleus located eccentrically with visible nucleolus. The ultrastructural description is as follows: well developed Golgi complexes, rough endoplasmic reticulum and mitochondria in moderate quantities. Electron-dense granules numerous. CS highly vascularized.

In this study a number of caves from various Brazilian limestone regions were surveyed. The information gathered expands and improves that of our preliminary article, allowing a reasonable good picture of the Brazilian cave fauna. There doesn't seem to be any striking difference between the composition of the Brazilian cave fauna and that of the other tropical regions that have been studied. Animals commonly found throughout the studied area include: Phalangopsidae crickets, Reduviidae heteropterans, Polydesmida and Juliformida millipedes, Opilionida Laniatores, and spiders, particularly Scytodidae, Ctenidae, Theridiosomatidae and Pholcidae. Among the vertebrates the commonest are barts and catfishes. Amblypygi are common in all regions except São Paulo...

The morphology of the mandibles of the alates and workers of the 8 soil-feeding genera with nasute soldiers from the Neotropical Region is studied. Three mandibular patterns are recognized : (1) Convexitermes, Atlantitermes, Araujotermes, Coatitermes, Subulitermes and Agnathotermes have mandibles with complete marginal dentition and no reduced teeth, (2) Angularitermes has mandibles with complete marginal dentition but two teeth are vestigial, and in (3) Cyronotermes the marginal dentition is incomplete. A set of other characteristics is associated with each of these mandibular patterns. Intraspecific variation are registered, either between the alate and the worker castes of all genera, as between the worker types of the dimorphic worker caste of the...

A arara-azul-de-Lear, Anodorhynchus leari Bonaparte, 1856
Provedor de dados: 104
Autores: Sick,Helmut; Gonzaga,Luiz Pedreira; Teixeira,Dante Martins.
The case of the Indigo, or Lear's Macaw, Anodorhynchus leari, is unique in South American ornithology. The species, although described more than 100 years ago, was known only through very few living specimens, which entered occasionally the bird trade, without any indication of their origins. It was presumed "probably some part of Brazil" (Salvadori, 1891). The last speculation was that it was unlikely, though not impossible, that the Indigo Macaw might not be an independem species, but rather, a hybrid between the two other well known blue macaws, Anodorhynchus hyacinthinus and A. glaucus (Voous, 1965).

Desenvolvimento morfológico de folhas de Hevea brasiliensis Muell. Arg. e H. pauciflora Muell. Arg. submetidas a dois regimes hídricos
Provedor de dados: 36
Autores: Pita,Francisco Antonio de Oliveira; Oliva,Marco Antônio; Silva,Eldo Antonio Monteiro da.
As características morfológicas relacionadas com a ontogenia foliar das espécies de seringueira foram influenciadas pela deficiência hídrica. O déficit hídrico provocou redução significativa no número de folhas, no comprimento do folíolo central, na matéria seca foliar, na matéria fresca foliar, na classe do ângulo folíolo-pecíolo e no tamanho da brotação em H. brasiliensis e H. pauciflora. A espessura dos tecidos anatômicos das folhas foi pouco modificada cm ambos os tratamentos, provavelmente devido ao pequeno efeito do curto período de aplicação do estresse hídrico e das condições do ambiente sobre a formação desses tecidos. No entanto, H. pauciflora tende a apresentor maior resistência à perda de água, quando comparada com H. brasiliensis (IAN 873),...

Autores: Marques Filho,Ari de O.; Ribeiro,Maria de Nazaré Góes.
Neste estudo foram analisados os dados de evaporação do tanque Classe A, coletados na Estação Climatológica que está localizada no km 14 da ZF-02, Rodovia Manaus-Caracaraí. Nesse local o parâmetro climático dominante no processo de evaporação do tanque é o déficit de saturação do ar, com um coeficiente de determinação R2 = 0,91 na equação de regressão resultante, enquanto a razão entre a evapotranspiração potencial, calculada pela fórmula de Penman, e aquela evaporação observada está vinculada à razão entre a diferença das temperaturas da superfície d1 água e do ar e o déficit de saturação, com o coeficiente de determinação R2 = 0,79.

Reproductive biology of Bellucia (MELASTOMATACEAE)
Provedor de dados: 36
Autores: Renner,Susanne S.
The reproductive biology of five of the seven species of Bellucia (Melastomataceae), a genus of shrubs and small trees, was investigated in Amazonia. Sucessful fruit-set by Bellucia requires floral visitation by bees. The flowers are produced continuously all year, and are visited by a wide variety of female bees, the principal pollinators being Xylocopa, Centris, Ptilotopus, Epicharis, Eulaema, Bombus, and Oxaea. The floral attractants are color and the odor produced by the pollen, stamens, and petals; the reqard is pollen. Three species of Bellucia are self-incompatible. Indiscriminate visitor behavior and lack of phenological, morphological, or genetic barriers lead to hybridization between sympatric species of Bellucia, and no more than two species...

Nutrição mineral de seringueira IV. Toxicidade de Boro em Hevea brasiliensis
Provedor de dados: 43
Autores: Haag,H.P.; Bueno,N.; Viegas,I.J.M.; Pereira,J.P.
Com freqüência observa-se no Brasil nas áreas de seringueira sintomas visuais de deficiência de boro, quer na fase de formação das mudas em crescimento em viveiro, quer no jardim clonal e mesmo nos primeiros anos de desenvolvimento das plantas definitivas. Foi também constatado que estas deficiências estão associadas com adubação de N, P, K, Mg. Este fato levou os autores a determinar a resposta a plantulas de seringueira a níveis crescentes de boro no substrato (0,5; 1,0; 1,5; 2,0 e 2,5 ppm de B). Plantulas do clone Tjir 1 foram cultivadas em vasos contendo como substrato silica moida, acrescida de solução completa com os níveis de boro acima indicadas. Nove dias após o ensaio dos tratamentos o efeito do boro se fez notar. As plantas cresceram com menor...

Autores: Primavesi,Ana Candida P. Aguirre; Malavolta,E.; Primavesi,Odo.
Foram determinados produção de matéria seca de raízes, colmos e folhas e teores de P, Ca, Mg, K, Al, Mn e Fe de três cultivares de sorgo sacarino (Br500, Br602 e Ample-H-OK) crescendo em solo Podzólico Vermelho Amarelo Var. Laras, em presença e ausência de corretivos da acidez do solo (calcário e silicato). Ocorreram diferenças genotípicas na resposta aos corretivos. O melhor tratamento para a produção de matéria seca das folhas não foi necessariamente o melhor para a produção de matéria seca dos colmos. O calcário propiciou efeitos relativos melhores que o silicato na promoção do crescimento dos cultivares. O cultivar Br500 apresentou a melhor resposta ao calcário e Br602 ao silicato.

Ensaio de combate químico ao ácaro da leprose Brevipalpus phoenicis (Geijskes, 1939) em pomar cítrico
Provedor de dados: 43
Autores: Silva,J.M.; Raizer,A.J.; Sugahara,C.A.; Motta,R.; Mariconi,F.A.M.; Scarpari Filho,J.A.
O ácaro da leprose Brevipalpus phoenicis é considerado o responsável ou um dos responsáveis pela transmissão da leprose em citros. O presente trabalho foi realizado com a finalidade do combate químico ao ácaro. Os tratamentos foram oito: pulverizaram-se cinco defensivos em diferentes formulações comerciais e dosagens, tendo cada laranjeira recebido 7,0 litros de calda. A análise dos resultados mostrou que o bromopropilato (tratamento padrão) se manteve eficiente durante todo o experimento; a clofentezina, na menor dosagem, foi bastante promissora e teve efeito residual relativamente longo.

Efeito do nível de fertilidade de dois solos submetidos a compactação sobre o comportamento do acumulo de matéria seca e nutrientes por feijoeiro (Phaseolus Vulgaris L.)
Provedor de dados: 43
Autores: Primavesi,O.; Mello,F.A.F. de; Muraoka,T.
Foi realizado um experimento em casa de vegetação com terra do horizonte A de um Oxisol (LR) e de um Alfisol (PVp), confinados em vasos com capacidade para 3,8 litros, cultivada com duas variedades de feijoeiro, em parcelas sem e com adubo mineral. As terras foram submetidas à compactação e mantidas à umidade entre 100 e 300 mbares de tensão. A matéria seca, que normalmente reduziu seu acúmulo com o aumento do nível de compactação, teve seu compartamento afetado pelo nível de fertilidade, mas sua intensidade de acúmulo afetada pelo tipo de solo. Considerando os valores absolutos dos elementos acumulados, verificou-se que o nível de fertilidade afeta o comportamento de N, P, Ca, B, Cu e Fe considerando a parte aérea, e o comportamento de K, Mg e Zn na parte...

História da fitovirologia no Brasil
Provedor de dados: 43
Autores: Costa,A.S.
O presente trabalho é uma revisão histórica sucinta da atuação de fitopatologistas, fitovirologistas e outros técnicos no Brasil na área das viroses de plantas. É considerado que a estrutura atual da pesquisa fitovirológica existente a nível federal ou estadual no país é suficiente para enfrentar problemas representados pelas viroses de nossas culturas. Mas é apontado que há falta de uns poucos centros de pesquisa básica com vírus de plantas independentemente de considerações econômicas de problemas existentes. É mencionado que há dificuldade. em obter recursos para qualquer instituição ou grupo que trabalhe em pesquisas mais básicas e que essas são melhor adaptadas a uma universidade ou instituto altamente especializado.

Efeitos do tratamento fungicida e de três ambientes de armazenamento sobre a conservação de sementes de seringueira
Provedor de dados: 43
Autores: Cicero,Silvio Moure; Marcos Filho,Julio; Toledo,Francisco Ferraz de.
No Estado de São Paulo, a coleta de sementes de seringueira se inicia em fevereiro e se prolonga até os meses de março/abril; os meses subsequentes se caracterizam por apresentarem um período relativamente seco e frio, inadequado para a instalação de viveiros. Desta forma, seria importante o armazenamento das sementes até os meses setembro/outubro. As sementes de seringueira perdem a viabilidade, em condições normais de ambiente, num período relativamente curto e exigem determinadas condições para o seu armazenamento; assim, estudaram--se no presente trabalho os efeitos do tratamento fungicida e de três ambientes de armazenamento sobre a qualidade das sementes acondicionadas em sacos plásticos.

Resistência de soja a insetos: VI. Comportamento de genótipos em relação a percevejos
Provedor de dados: 53
Autores: Rossetto,Carlos Jorge; Igue,Toshio; Miranda,Manoel Albino Coelho de; Lourenção,André Luiz.
O comportamento de trinta e cinco genótipos de soja foi estudado em condições de campo, em Campinas, SP, em relação ao ataque dos percevejos pentatomídeos Euschistus heros (F.), Piezodorus guildinii (Westwood) e Nezara viridula (L.). A infestação natural do campo experimental foi suplementada com a liberação de percevejos adultos. Em 1983/1984, o dano médio sofrido pelos genótipos foi moderado e, em 1984/1985, severo. Três critérios foram utilizados para avaliar a resistência das variedades: a porcentagem de área foliar retida após a maturação das vagens, o índice porcentual de dano de vagem e a produção de grãos. A testemunha suscetível usada foi o cultivar Paraná, que produziu apenas 402kg/ha e 31kg/ha em 1983/ 1984 e 1984/ 1985 respectivamente. A...

Neste trabalho, determinou-se o tamanho da amostra para estudos de danos causados pelo caruncho Sitophilus zeamais Motschulsky, avaliados pelos métodos da escala visual de notas e do número de grãos danificados em relação ao total de grãos. O critério adotado para estimar o tamanho da amostra foi de que esse tamanho permitisse detectar uma diferença de 10 ou de 20% da média geral entre médias de danos, em cultivares de milho, e avaliar o dano médio por cultivar com um erro-padrão de 10 ou de 20% da média. Discutiu-se, também, a eficiência dos dois métodos para avaliar o dano causado pelo caruncho. Foram utilizados dados de dois experimentos de laboratório, conduzidos nos anos agrícolas de 1978/79 a 1979/80, realizado no Instituto Agronômico, Campinas. O...

Autores: Espironelo,Ademar; Gallo,José Romano; Lavorenti,Arquimedes; Igue,Toshio; Hiroce,Ruter.
Foram utilizados oito ensaios de adubação NPK, em cana-soca do cultivar CB41-76, conduzidos em diversos solos do Estado de São Paulo, sendo quatro em Latossolo Roxo, um em Latossolo Vermelho-Amarelo textura argilosa, um em Latossolo Vermelho-Amarelo textura média, um em solos Podzolizados de Lins e Marília variação Manilha e outro em variação Lins. Aos quatro meses de idade da cana-soca, amostras de folhas + 3 foram coletadas para fins de análise de macronutrientes. As variações dos teores de macronutrientes foram mais acentuadas entre localidades do que entre doses dos respectivos adubos. Correlações positivas e significativas foram obtidas somente entre os teores de potássio nas folhas e as produções de cana. Devido às variações acentuadas dos teores de...

Autores: Azzini,Anísio; Benatti Junior,Romeu; Arruda,Maria Carla Queiroz de.
Foram estudadas seis variedades de juta quanto à densidade básica do caule e seus teores em líber, lenho, fibra, celulose e dimensões das fibras. Os valores para a densidade básica, de 0,270 a 0,335g/cm³, evidenciaram suas diferenças tecnológicas. Os caules da variedade introduzida sob nº I-52445 foram os menos densos, com menores teores de fibra e de celulose. Os teores de líber (36,6 a 40,6%), lenho (59,4 a 63,4%), fibra (17,3 a 22,0%) e celulose (42,4 a 45,4%), bem como o estudo micrométrico das fibras liberianas e lenhosas, evidenciaram as possibilidades de utilização dos caules de juta como matéria-prima para produção de fibras celulósicas para papel.

Sacarificação da serragem de bambu visando ao estabelecimento de um método de determinação de amido
Provedor de dados: 53
Autores: Azzini,Anísio; Arruda,Maria Carla Queiroz.
No presente estudo, determinaram-se as condições de hidrólise da serragem de colmo de bambu (Bambusa vulgaris Schrad.), visando ao estabelecimento de um método de determinação de amido. Os resultados obtidos mostram que as condições mais adequadas de sacarificação de amido na serragem foram obtidas em solução de ácido sulfúrico na concentração de 2% (v/v), após 60 minutos de reação sob refluxo, empregando-se uma relação de 1:30, entre a quantidade de serragem e o volume da solução. Nessas condições, o teor de amido no colmo (A) foi calculado em função do rendimento em glicose proveniente da hidrólise do amido (Gh), do teor de glicose na serragem (Ga) e do fator de conversão de glicose para amido (0,9), através da seguinte expressão: A = (Gh - Ga) x 0,9.

São relatados e discutidos resultados de produção obtidos em vinte e quatro ensaios de adubação com o algodoeiro, conduzidos em diferentes solos das principais áreas produtoras paulistas de 1975 a 1984. Para avaliar o efeito da adubação nitrogenada, doses de 0,25 e 50kg/ha de N foram fornecidas em cobertura logo após o desbaste, 30 a 40 dias após a emergência das plantas. Em três outros tratamentos, a dosagem de 50kg/ha de N foi parcelada, sendo fornecida metade no desbaste e metade em fases posteriores do ciclo, a saber. 45-55, 65-75 e 85-95 dias de idade. Nesses tratamentos, o sulfato de amônio forneceu o nitrogênio. Uma cobertura com uréia (50kg/ha de N), no desbaste, completou o quadro de tratamentos, estudados em esquema de quadrado latino 7 x 7....

Provedor de dados: 53
Autores: Camargo,Marcelo Bento Paes de; Brunini,Orivaldo; Miranda,Manoel Albino Coelho de.
O estudo foi baseado em dados fenológicos obtidos de experimentos conduzidos pela Seção de Leguminosas do Instituto Agronômico, em Campinas, Ribeirão Preto e Pindamonhangaba, durante os anos agrícolas de 1977/78, 1978/79 e 1979/80 para os cultivares de soja UFV - 1, Viçoja, Santa Rosa e Paraná. A partir desses dados, desenvolveu-se um modelo agrometeorológico de estimativa de produção de grãos, baseado na penalização de produtividade potencial de cada cultivar de soja, em função das condições meteorológicas reinantes durante o desenvolvimento da cultura. O modelo proposto foi o seguinte: YEst = (YPot) x (FTer) x (FDef) x (FExc), onde: YEst = produtividade estimada em grãos (kg/ha); YPot = produtividade potencial do cultivar em cada localidade (kg/ha); FTer...

Autores: Gallo,Paulo Boller; Mascarenhas,Hipólito Assunção Antonio; Bataglia,Ondino Cleante; Quaggio,José Antonio.
No ano agrícola 1983/84, conduziu-se um exerimento num Latossolo Vermelho-Escuro álico na Estação Experimental de Mococa, SP, plantando o sorgo cultivar Contigrão 111 em parcelas que receberam calagem em 1980 nas doses equivalentes a 1, 4, 7 e 10t/ha de calcário dolomítico, e foram cultivadas por três anos com soja. Nas subparcelas, aplicaram-se 0, 40, 80 e 120kg/ha de nitrogênio em cobertura 35 dias depois da germinação. Os resultados mostraram que a calagem elevou substancialmente a produção, mesmo com a drástica deficiência hídrica ocorrida na fase reprodutiva da cultura. A calagem eliminou as limitações impostas pela toxicidade de alumínio e aumentou a disponibilidade do nitrogênio proveniente dos restos da cultura de soja. Em todos os níveis de...

Autores: Maeda,Jocely Andreuccetti; Razera,Luiz Fernandes; Lago,Antonio Augusto do; Ungaro,Maria Regina Gonçalves.
Vinte lotes distintos de sementes de girassol foram submetidos ao envelhecimento rápido a 42°C e 100% de umidade relativa, por 0, 24, 48, 72, 96 e 120 horas, com o objetivo de determinar o tempo de exposição que melhor discriminasse os lotes pelas suas repostas de germinação após o envelhecimento. Os resultados mostraram que os lotes exibiram grandes diferenças entre si quanto ao grau de resistência às condições desfavoráveis impostas pelo envelhecimento rápido, inclusive aqueles com porcentagens comparáveis de germinação inicial. Esse comportamento variável não pôde ser estimado pelo teste inicial de germinação. O período de 72 horas de exposição na câmara foi o que ofereceu melhor discriminação entre os lotes de germinação inicial mais alta. Entre os...

Um método alternativo para arrancamento de cafeeiros é apresentado neste trabalho: consiste ele em uma garra arrancadora presa ao cafeeiro e tracionada por trator. Determinações realizadas no Centro Experimental de Campinas, em latossolo roxo, em fevereiro de 1984, demonstraram que o esforço médio requerido foi de 2.127 kgf por planta para C. canephora L. cv. Robusta e de 1.158 kgf por planta para C. arabica L. cv. Mundo Novo. Dentre os sistemas utilizados, o mais indicado foi o arrancamento de três cafeeiros sucessivamente, alinhados no sentido tratório em esforços independentes, numa só operação. Sua utilização propiciou menor movimento de solo do que no uso de trator com lâmina. Foi possível o emprego de um trator de pneus de potência de 100 cv.

Autores: Cervellini,Genésio da Silva; Toledo,Sérgio Vasco de; Reis,Antonio Junqueira; Rocha,Túlio Ribeiro.
Nitrocálcio nas quantidades de 60, 120, 180 e 240 gramas de N por cafeeiro e por ano foi aplicado em parcelamentos diferentes, de acordo com os tratamentos e em três locais com início em 1973/74: Centro Experimental de Campinas, Estação Experimental de Mococa e Estação Experimental de Ribeirão Preto. Foram estudados os efeitos das quantidades crescentes e avaliadas as conveniências do parcelamento das doses de N aplicadas. Os acréscimos de produção com a elevação dessas doses foram bastante grandes até 120g, passando, a partir dessa quantidade, a aumentos menores. Os efeitos residuais do sulfato de amônio, Nitrocálcio, uréia e salitre-do-chile aplicados quatro anos antes do início do experimento ainda afetaram as produções, passados dez anos das últimas...

Autores: Maeda,Jocely Andreuccetti; Salgado,Antonio Luiz de Barros; Lago,Antonio Augusto do.
Sementes de Crotalaria juncea L. com conteúdos de umidade de 6,3 e 11,1%, foram armazenadas por 84 meses em condições ambientes e às temperaturas controladas de 20 e 30°C, e testadas periodicamente no laboratório quanto a germinação e vigor (índice de velocidade de germinação) e no campo quanto a emergência, altura da planta, produção de massa seca (massa vegetal na maturação) e de sementes. Até aos 30 meses, não se observaram diferenças significativas de germinação entre as sementes nas diversas condições, apresentando todas porcentagens acima de 90. Dos 30 meses em diante, as sementes armazenadas nas condições de maior umidade e temperatura exibiram maior velocidade de deterioração, notadamente as mantidas com 11,1% de umidade a 30°C, que mostraram...

Autores: Pereira,Antonio Roberto.
O balanço hídrico de um solo podzolizado de Lins e Marília cultivado com cafeeiros de diferentes idades e tamanhos, ou seja, 'Mundo Novo' com livre crescimento (18 anos; altura - 3m), 'Mundo Novo' recepado (3 anos; altura - 2m) e 'Catuaí' (4 anos; altura - 1,5m), foi realizado no período entre duas colheitas (1971/72), na Estação Experimental de Pindorama, utilizando a técnica de moderação de nêutrons até 2,4m de profundidade. Este tipo de solo reteve cerca de 1mm de água por centímetro de profundidade quando submetido à tensão de 15atm. A ocorrência de uma camada adensada entre 60 e 90cm de profundidade ajudou a reter a umidade na parte superior do solo, dificultando a drenagem profunda. Os armazenamentos mínimo e máximo observados representaram,...

Autores: Lopes,Eli Sidney; Perón,Sonia Cristina; Portugal,Edilberto Princi; Giardini,Antonio Roberto.
A adição de vinhaça na cultura canavieira tem sido praticada em áreas próximas às usinas de cana. Seria de interesse a avaliação do efeito da vinhaça no Rhizobium presente no solo (autóctone), uma vez que leguminosas têm sido indicadas para cultivo intercalar com a cana. Um experimento foi conduzido em casa de vegetação, com o objetivo de verificar a influência da aplicação contínua, durante três anos, de concentrações crescentes de vinhaça (0, 100 e 1.000 m³/ha/ano), com intervalos de seis meses entre aplicações, na população autóctone de Rhizobium que nodula amendoim, soja, feijão e crotalária. Em cada cultura, foram usados controle com solo sem adição da vinhaça e um tratamento inoculado com uma estirpe de Rhizobium de conhecida eficiência, recomendada...

Autores: Lordello,Rubens R. A.; Lordello,Ana Ines Lucena; Donalisio,Mario G. R.
The jaborandi (Pilocarpus microphyllus Starf.) is a medical plant found in Maranhão State, Brazil, which is the natural source of the drug pilocarpine used to treat glaucoma, a disease that frequently causes blindness. The leaves used for extraction of pilocarpine are presently collected from plants that grow naturally. Instead of pure extractive exploitation it has been tried the cultivation of this plant in order to improve and increase the production. Nevertheless, 90% of 160,000 young seedlings were lost due to the infestation of Meloidogyne incognita race 1. Research showed the soil as the source of infestation.

Neste estudo procurou-se estabelecer as correlações entre a densidade básica do colmo e os valores de Brix e Pol em diversas variedades e "seedlings" de cana-de-açucar, visando ao estabelecimento de um método expedito e semiquantitativo de análise. Os resultados obtidos mostraram correlações significativas (p &gt; 99%) entre a densidade básica do colmo e os valores obtidos para Brix e Pol, principalmente para a região mediana do colmo. Desse modo, a densidade básica do colmo pode ser utilizada como um método expedito de análise para avaliar a concentração de sacarose em cana-de-açúcar.

Enorme desafío constituyó la realización de la presente tesis puesto que si bien mucho se ha escrito sobre el tema de la intervención estatal, sobre todo desde la óptica filosófica, política y sociológica; no ha existido un trabajo sistematizado desde el punto de vista jurídico. La evidente actualidad del tema y sus profundas connotaciones para la sociedad motivaron este intento, insuficiente de todas maneras, de tratar el tema de la intervención desde el punto de vista histórico-jurídico.
