A study was made for zinc-65 and manganese-54 accumulation and excretion by the Eucalanus elongatus and Idotea metallica zooplankton species. The intensity of the excretion by zooplankters of the radionuclides intaken with food does not depend on the type of food objects and specimen individual masses. The excretion rates of zinc-65 and manganese-54 intaken with food are observed to be different. Zinc is accumulated and excreted more intensely than manganese. The evidence obtained presents interest for solving problems of biogenic migration of microorganisms in the sea.

Исследование процессов потребления и ассимилияции органических веществ морским ежом Strongylocentrotus droebachiensis (O. F. Muller)
Provedor de dados: IBSS Repository
Autores: Холодов В. И.; Поповичев В. Н.
In the S. droebachiensis ontogenesis the maximum-to-average rations values increase. This permits large animals to shorten the period of transition from the maximum ration to the average one and to keep the latter at a relatively constant level. The variations in the average daily rations are associated with the period of food digestion, therefore the digestion period may be measured without using the labelled food. Studies on the processes of accumulation and assimilation by Strongylocentrotus droebachiensis of the suspendable and soluble substrates of different chemical nature by the method of chamber analysis made it possible to find out significant peculiarities of these processes. Duration of accumulation, mass of chambers accumulating different...

Autores: Ермолаев К. К.
The number of phenol-decomposing microorganisms is found to decrease regularly in all seasons while moving forward from the littoral zones into the open sea. The highest number of bacteria possessing a high phenol-decomposing activity was isolated in ports and adjoining water areas. Phenol is stated to most actively decay in water taken from the places when the pollution with this toxicant is the highest. Phenol bio-decay is shown to be most effective under the influence of temperature and biogenic salt K2HPO4. Studies of the most important biochemical components of the bacterial cell, DNA, RNA, free nucleotides, lipids and protein, in the process of phenol biodegradation by the Bacterium album culture reveal a considerable decrease in total protein and a...

Changes in the activity of succinate dehydrogenase (SDH) are studied in different tissues of mussels under effect of copper-containing poisons. A dependence is established between the degree of the SDH activity inhibition and copper ions concentration. Two methods for determining efficiency of copper-containing poisons are compared (hydrobiological - by survival rate and biochemical - by the SDH activity inhibition). The data on this enzyme activity are suggested to be used as a test for estimating the poison efficiency.

The luminescence spectra were studied for single cells of certain sea algae species in the normal state and as affected by the spectrum visible region (436 nm) radiation. The initial luminescence spectra of green, diatomaceous, golden and brown algae are shown to differ insignificantly. Certain differences are found in changes of the spectra during photodestruction of interacellular luminescent compounds under the effect of the radiation exciting the luminescence. The luminescence spectra of the red and blue-green algae differ from those of representatives of other divisions because the former contain phicobilins, and this difference is most pronounced in the process of pigment photodestruction. The data obtained show that the luminescent spectral...

Provedor de dados: IBSS Repository
Autores: Кирюхина Л. Н.
Hydrocarbon composition of bottom sediments was studied in some bays in the south-western part of Crimea. The content of bitumoids in mud influenced by anthropogenic factor is one-two orders higher than that in the open sea sediments. Oils predominate in the bitumoids of the littoral mud. Their amount is three times as high as compared to bitumoids in the open sea. Oil accumulation is accompanied by the concentration of methane-naphthene hydrocarbons and decrease of heterocyclic hydrocarbons. Alkanes, both normal and isoprenoid, appear to be ten times as high in such sediments as in those of the open littoral zone. Pristane and phytane account for a third of isoprenoids.

Quantitative changes in the consumption rate and efficiency of assimilating a mixture of food organisms (unicellular algae, phytogenis detritus, Artemia fry) are considered as dependent on the age of Euchaeta marina. The nutrition type in  the animal ontogenesis is shown to change from the filtration to predatory one mainly. The assimilation efficiency was determined by the type of the offered food: vegetable food resulted in high and constant values (86.2-94.1%), whereas the animal food increased (from 26.5 to 62.0%) and the detritus decreased them (from 89.2 to 58.1%) from fry to adults.

Seven petroleum aggregates (of 30 mm diameter) caught in the East Atlantic region are found to contain 81 specimens of free-living nematodes. 80 of them belong to the Chromadarina cf. laeta (de Man 1876) Mic. 1924 species, one belongs to Camacolaimus sp. Ch. cf. laeta is represented by juvenile and puberal forms (males and females). Detection of considerable number of nematodes shows that inside the petroleum aggregate there exist rather favourable living conditions for eurybiont species. This group of organisms is likely to utilize petroleum aggregates not only as a substrate but is able to actively digest their organic components.

Autores: Бурлакова З. П.; Лаврентьев Н. А.
A relative heterotrophic potential of microplankton was studied in the south-western sector of the South Atlantic anticyclonic circulation according to accumulation of 14C labeled organic substrates: hydrolyzate of Diatomeae, hydrolyzate of Dinoflagellata, glucose, glycin, leucine and glycolic acid. The microplankton heterotrophic potential is shown to depend on the types of the water masses. The concentration of the introduced substrates being 0.2 mg/l^-1, the microplankton heterotrophic potential of different water masses varied between 0.009 and 1.4 mgC/m^3/day. Its lowest values (0.009 = 0.042 mgC/m^3/day) are obtained in the transitional zone between the subtropic and subantarctic waters and in waters of the Folkland Current. The heterotrophic...

Processing of 700 bathometer assays sampled in April-August 1976 was the basis to analyse distribution of microzooplankton in seas of the Mediterranean basin and south-western sector of the South Atlantic anticyclonic circulation. It is shown that in seas of the Mediterranean basin the planktonic communities in the period of the studies were at different stages of the seasonal succession. In the south-western Atlantic the development of microzooplankton is associated with different origin of water masses and dynamic processes in the southern subpolar front zone. Differences are observed in the vertical distribution of microzooplankton, they depend on peculiarities of water dynamics and development of phytoplankton and bacteria. A high content of...

Lethal termination comes with the copper content of 45-70 mg/kg mussel ash dry mass. The range between the minimum toxic dose and absolutely lethal one for mussels is within the limits of 25-125 mg/l. During the first 48 hours copper is accumulated in the liver, muscles, gills, gonads, mantle fluid. On the 12th day of the experiment the highest amount of copper is found in the gills. The accumulated copper is excreted by the organism for 30 days.

Suspended matter with a particle size typical of the sea and ocean suspensions (0.4-100 mkm) in water of the estuary sections of some rivers inflowing into the Black and Azov seas averages to 18.5% of total silt content. In this connection the contribution of the rivers sediment runoff contribution to the suspended matter of the World ocean is estimated. Thus, the contribution made by all rivers of the terrestrial globe is calculated to be 3000-7000 mill. t per year, the losses resulted from sedimentation of the particles at the junction of the river and sea waters being taken into account.

Changes were studied in the luminescence spectra of "olive-green" algae single cells in normal state and as affected by formalin and 365 and 436 nm radiation. It is shown that the observed visually color of cell luminescence is determined by the presence of the compounds luminescent in the range of 530-550 and 687-690 nm cells fixation with formalin causes changes in the luminescence spectra. The analogous changes are observed during photodestruction of the luminescent intracellular compounds. In the cell radiation spectra no radiation bands belonging to phycobilins are found. The olive-green cells are suggested not to belong to fungi spores as well as to the blue-green or red algae.

The data on the Sevastopol bay mussels respiration made it possible to find out the character of their oxygen when they were maintained in groups and separately in respirometers of different size. Metabolism rate in mollusks is connected with the volume of experimental vessels and density of the animals in them. Less intensive respiration of mussels in a group taking place in one of the variants of experiments is due to a more than 20% decrease in oxygen tension in water (as compared to the initial one) and to accumulation of metabolism products, which results in prevalence of glycolytic way of energy production in the mussels. Under sea conditions the metabolism rate in mollusks in the fouling cenosis is not constant and alongside with other factors is...

The mitochondria were isolated by the method of Schnieder and Hogebum, their respiration was determined polarographically in the Gubler medium. DDT is established to decrease the hepatopancreas mitochondria respiration both in the in vivo and in vitro experiments. The DDT effect is based on influencing biomembrane permiability and on disturbance of redox processes. The complex vitamins somewhat prevent this effect thus increasing the membrane resistance to the DDT action.

The degree of mollusks effect on the fouling community microconditions at the stage of dynamic equilibrium is presented based on the results of studies in oxygen uptake by mussels and the dynamics of dissolved organic substance (DOS) excretion. The exponential equations are obtained reflecting the dependence of specific rate of DOS excretion on the mass of mussels. It is shown that the delivery of external metabolites to the environment in time is described in most cases by the second order equations. The regression equation is derived which reflects the interrelation between mollusks respiration and DOS content. It is established that DOS delivery due to mussels vital activity occurs mainly in the process of digestion and especially of reproduction. It...

Autores: Битюков Э. П.; Иванова А. П.
The number of sound-scattering layers (SSL) in the south-western part of the anticyclonic circulation of the Southern Atlantic increased from the equatorial water mass south-westward. Most frequently three distinctly pronounced SSL were observed, but in regions with elevated level of biological production their number reached seven. Diurnal vertical distribution of SSL was characterized by their sinking to the depth in the morning and upwelling to the surface in the evening.

Autores: Крупаткина Д. К.; Кузьменко Л. В.
The primary production in the Sargassian sea was measured by three methods: radiocarbon (Sorokin, 1956), chlorophyllic (Finenko, 1966) and a modification of the radiocarbon method which takes into account phytoplankton adaptation to the light. Comparison of the results showed that the primary production value measured by the modified radiocarbon method is on the average 105.7% higher than the values obtained by the radiocarbon method. The chlorophyll method values for the primary production were 49.6% higher than those of the radiocarbon method and 17.7% lower than those of the modified radiocarbon method.

Water masses are typified according to the intensity of bioluminescence and its structure. The most intensive bioluminescence was observed in equatorial waters, the Brasil Current and in the transformed waters of the Brasil and Folkland Currents as well. In the central part of the anticyclonic circulation, in subtropical waters, in streams of the Folkland Current and in the northern part of the subantarctic water mass bioluminescence is three-five times weaker. The common feature of the bioluminescence distribution over the latitude hydrofront was its  increased level in the eastern parts of the adjoining currents.

Autores: Сергеева Н. Г.
86 species of Nematoda are found in the growth of Cystoseira barbata Ag. (Wor.) at depths of 1,3 and 5 m. Only 29 species are common for the three depths. The number of Nematoda in 1970-1971 varied from 800 to 114200 ex./kg of Cystoseira, the amount of biomass ranged form 0.4 to 198.6 mg/kg of the alga. In the spring-summer period their number is at the level of maximum development, in the autumn-winter period it sharply decreases. No clear dependence was found for the changes of the Nematoda number on the depth. The highest number of the Nematoda species was observed in spring and summer. With respect to the species abundance and the number in the Nematoda community the Chtomadorida (27 species) and Enoplida (20 species) orders are prevailing....

The energy balance main elements were studied in mass species of copepods depending on the food kind and temperature. It is shown that most animals of the southern part of the Atlantic Ocean fed on living unicellular algae and phytogenic detritus in comparable amounts. Total diurnal rations decreased from 55.9 to 7.5% with an increase in the energy equivalent of the body mass from 0.062 to 1.5 cal*sample^-1. The value of alga and detritus assimilability was 40-60% on the whole. The relation of the ration and amount of the assimilated food to the copepod body mass for 10-12deg Celcius is described by the equations: C = 0.090*W^0.353, A = 0.040*W^0.383, and for 14-16deg Celcius: C = 0.090*W^0.717, A = 0.026*W^0.419.

A produção de bovinos no Brasil e, em grande parte, sustentada por pastagens nativas. A produtividade destas pastagens e, por outro lado, geralmente baixa, necessitando-se de pesquisas que desenvolvam tecnologia para seu melhor aproveitamento como fonte de alimento para ruminantes. A baixa produção de bovinos nos trópicos deve-se, em parte, a um subconsumo de matéria seca geralmente de baixa digestibilidade, resultando em baixo consumo de nutrientes digestíveis. Dai a grande importância dada a estimativa do consumo animal em pastejo, que tem o objetivo de fornecer subsídios para melhorar a produtividade animal, bem como de se relacionar os índices de valor nutritivo e consumo de nutrientes com as taxas de ganho alcançadas.

Com base nas observacoes efetuadas, podem ser enumerados varios pontos importantes quando do estabelecimento de pastagem cultivada: 1) Controle da vegetacao arbustiva nao desejavel atraves do desmatamento com grade pesada, a uma profundidade adequada. Apos o desmatamento, uma ou duas gradagens com grade hidraulica sao necessarias para diminuir a presenca das invasoras herbaceas que pode, tambem prejudicar o estabelecimento das forrageiras. 2) Face a baixa fertilidade do solo deve ser feitas uma adubacao com fosforo e potassio para permitir o melhor estabelecimento da pastagem plantada. Aconselha-se que a distribuicao dos adubos sejam feitas em linhas, de modo a aumentar o seu aproveitamento pelas plantas e diminuir a fixacao pelo solo. 3)Alem destes...

Autores: PORTO, J. C. A.; VALLE, E. R. do; LIMA, O. P.
O presente estudo tem por objetivo verificar o efeito do uso da pastagem cultivada, durante a estação seca do ano, sobre o desempenho reprodutivo de novilhas neloradas, que tiveram a primeira cria aos 36 meses de idade. Durante três anos consecutivos, três grupos de novilhas, no terço final de gestação, (um grupo por ano) serão mantidas em pastagem de Setaria anceps, de maio a outubro, sob três diferentes cargas animais: 0,75, 1,00, 1,25 UA/ha. O efeito das diferentes cargas animais será médio através do peso das novilhas ao primeiro parto, e verificado a influência destes pesos no período do serviço e taxa de concepção das novilhas. Durante o primeiro ano de estudo (1978), um grupo de 36 novilhas neloradas, no terço final de gestação, foi submetido a três...

O controle eficiente e econômico de plantas daninhas é um dos principais fatores de alta produção em todas as culturas. Na cultura da seringueira, não será exagero afirmar que, em sua fase inicial é este o problema técnico mais difícil de resolver, muito especialmente na região Amazônica, onde as condições climáticas favorecem o desenvolvimento de uma flora infestante cuja composição é extraordinariamente variada, exigindo, por conseguinte, um maior número de capinas para manter o cultivo em boas condições de vegetação. Neste trabalho procurou-se estudar o efeito de diferentes doses de misturas de herbicidas, aplicados em pré e pós-emergência, objetivando maior eficiência no controle das plantas daninhas, na cultura da seringueira, nas condiç3es...

Sob o "Enfoque Sistêmico" da Filosofia de Pesquisa do CPATSA/EMBRAPA, o processo de pesquisa se inicia no Produtor com o conhecimento e interpretação da realidade e termina no Produtor com a incorporação dos resultados de pesquisas no seu sistema produtivo. Concebendo os momentos de geração, difusão e adoção tecnológica como indissociáveis no mesmo processo de comunicação, torna-se necessária a intervenção equitativa de todos os "sujeitos" interessados, para que suas respectivas percepções e interpretações sobre a realidade e suas necessidades se fertilizem reciprocamente gerando consenso quanto as ações que apontem para objetivos comuns.

Entre os diversos cereais usados na alimentação humana, o arroz é dos mais importantes e constitui o alimento básico de numerosas populações que vivem em regiões tropicais de clima úmido. O atendimento das necessidades de alimentos das populações, o estabelecimento de estoques reguladores e a obtenção de excedentes exportáveis, impõe aos técnicos e produtores a busca de novas tecnologias que possibilitem aumentar a produção do cereal, a fim de superar ou pelo menos equilibrar a demanda do produto no mercado mundial. A produção de novas cultivares de alto rendimento é mais lucrativa do que a das tradicionais, porque elas requerem menos sementes por hectare e apresentam resistência aos danos causados por certas pragas e doenças, condicionando...

O presente trabalho tem por objetivo discutir algumas limitacoes ao desenvolvimento da pecuaria na regiao de "mimoso", bem como sugerir medidas para uma exploracao mais racional e economica desta regiao. Na utilizacao de pastagem deve ser observado um numero adequado de animais por area. Nas pastagens sem adubacao recomenda-se cerca de 3 ha para cada animal adulto e, nas adubadas 2 hectares. Aconselhavel a divisao dapastagem em piquetes, de acordo com as categorias animais (por exemplo, um piquete para vacas com bezerros, vacas secas e touros, outro parabezerros desmamados, etc.). A adubacao com fosforo, mesmo em pequena quantidade aumenta e melhora a qualidade da pastagem, devendo ser repetida a cada 3 anos. Agua e sal mineral devem estar constantemente a...

A fim de se determinar o período mais favorável ao plantio de consorciação do capim marangá com as leguminosas centrosema, siratro e estilosantes, visando-se gerar informações básicas para um eficiente estabelecimento de pastagens consorciadas em áreas de Cerrado, está sendo conduzido um estudo de sucessivas épocas de semeaduras no CNPGC, Campo Grande,MS. As semeaduras são efetuadas com intervalos de 14 em 14 dias, de setembro a fins de fevereiro. O estudo foi iniciado em 1978 e devera ser concluído em 1981. A área experimental, que apresenta um solo do tipo Latossolo Roxo Alico textura argilosa, de baixa fertilidade natural e bastante infestado por ervas invasoras, foi preparado em fins de agosto de 1978 com aração e gradagem. Naquela ocasião, foram...

Autores: VALLE, C. B. DO.; ZIMMER, A. H.; PIMENTEL, D. M.
O insucesso na formação de pastagens cultivadas no Cerrado deve-se, principalmente, a falta de conhecimento sobre técnicas de implantação das mesmas. Com o objetivo de gerar algumas dessas informações básicas, foi iniciado em 1978 um estudo comparativo entre épocas de semeadura utilizando-se três espécies do gênero Brachiaria, visando a formação das pastagens no menor tempo possível.

Comportamento de cultivares e linhagens de arroz de sequeiro na microrregião do Alto Purus - Acre.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: CAMPOS, I. S.
A cultura do arroz no Estado do Acre é desenvolvida em solos de terra firme (arroz de sequeiro), grande parte em consórcio com milho (cultivo de subsistência), apresentando baixa produtividade (Kg/ha), dada a inexistência de cultivares altamente produtivas adaptadas à região, bem como o baixo nível tecnológico e a não utilização de insumos modernos. A falta de diversificação de germoplasma é um dos mais expressivos fatores limitantes da produção e da produtividade, face a problemas como acamamento, doenças e outros fatores adversos que influem direta ou indiretamente no rendimento da cultura. A adoção rápida de novas cultivares de alto rendimento e práticas de cultivos melhoradas promoveram grandes aumentos de produção, em parte devido a um maior...

Manejo silvicultural em seringais nativos, na microrregião Alto Purus - Acre.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: CASTRO, F. de A.
As características climatológicas constituem fatores de grande importância na germinação, crescimento e desenvolvimento das plantas. Quando esses fatores nãos satisfazem as exigências de uma determinada espécie, esta não pode completar seu ciclo vital. A "Hevea brasiliensis" é uma espécie cujo ponto de compensação luminosa é mais alto que a intensidade de luz sob a manta fechada. A exigência de alta intensidade luminosa é comprovada pelo fato de apenas serem encontradas plântulas em clareiras naturais. A seringueira, nos estádios iniciais, deve suportar uma fase de forte supressão e, mesmo aquelas que ultrapassarem a esta fase, mas que ainda não são emergentes, devem ter o crescimento fortemente. restringido. O desbaste, portanto, para eliminação de sombra...

Introdução e avaliação de cultivares de arroz, Estado do Acre.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: CAMPOS, I. S.
A lavoura arrozeira acreana apresenta um rendimento baixo, motivado não apenas pelos sistemas de cultivo usados pela maioria dos agricultores mas principalmente, devido a pouca diversificação e inferior qualidade do germoplasma, no que tange a produtividade. Através de levantamento que vem sendo executado por esta Unidade, em contato direto com o agricultor, pode-se notar uma grande mistura varietal nas sementes utilizadas, principalmente, por aqueles não atingidos pelos serviços de revenda estadual. A introdução de novas cultivares de arroz de boa produtividade, adaptadas às condições da região, é um imperativo para elevar a produção da cultura, cujo eventual aumento que vem se observando, deve-se ao incremento na área plantada. Esta introdução e...

Estudo da fotossensibilização hepatógena em bezerros em pastagem de Brachiaria decumbens cv. Australiana.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: SCHENK, M. A. M.; SCHENK, J. A. P.
A fotossensibilizacao em bovinos, embora ha bastante tempo conhecida, tornou-se evidente no Brasil, somente apos a ocorrência de vários casos no município de Rio Verde de Goiás, principalmente, em bezerros pastejando Brachiaria decumbens cv. Australiana. Pelo fato desta gramíneas estar bastante difundida no Pais tornam-se necessários estudos para se observar alguns aspectos sobre a fotossensibilização em bezerros. Com esta finalidade foi instalado, em maio de 1978, um experimento onde foram utilizados 90 bezerros entre 7 a 8 meses de idade. Estes animais foram divididos em 3 lotes sob os seguintes tratamentos: Lote A: bezerros em pastagem de B. decumbens desde 30 dias antes do desmame. Lote B: bezerros desmamados e colocados permanentemente em B....

Autores: MONTEIRO, L. A.; GARDNER, A. L.; CHUDLEIGH, P. D.
The work presented here is a first attempt, using computer simulation, to bring together some of the factors in an extremely complex bio-socieconomic system which would be virtually impossible to study as a whole using conventional field experimentation. The model to be described does require modification to make it more relevant to actual commercial conditions but, even in its present state, the broad outline of the results of managerial decisions can be determined and thus future investigations can be narrowed down to the most promising systems.

Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: COSTA, A. L. da; ALENCAR, M. das G. M. de.
A brucelose ou aborto infeccioso é uma doença infectocontagiosa causada pela Parvobactéria do gênero Brucella, cocobacilos imóveis, gram negativos, sem cápsula e sem esporos. Nos bovinos a Brucelose é causada principalmente pela Brucella abortus e menos comumente pela Brucella melitensis e Brucela suis e sua importância econômica é muito grande, pois a produção de bezerros fica reduzida a 40%; a produção de leite decresce em cerca de 20%; de cada cinco vacas que aborta uma fica estéril, favorecendo ainda a incidência de mamites, isto acrescido do fato da doença ser uma zoonose, transmissíel ao homem que bebe leite infectado cru. O aborto ou parto de animais infectados é o fator mais crítico para manutenção do ciclo infeccioso e que cada aborto causado por...

Autores: VALLE, C. B. do; SILVA, J. M. da; EUCLIDES, V. P. B.; GARDNER, A. L.
A produção de carne em regime extensivo não permite o uso de tecnologias de alto custo. Uma técnica simples a fim de se criar uma reserva de forragem para a estação seca consiste em deixar essa forragem se acumular no campo, na forma de um feno em pe. Cabe ressaltar que no Cerrado do Centro-Sul ha crescimento de forrageiras durante a estação seca, dada uma precipitação esperada em torno de 100-200 mm de maio a outubro. Para se obter uma primeira estimativa das espécies que poderiam ser manejadas para cumular matéria seca sem grandes perdas de valor nutricional, idealizou-se um experimento em parcelas, incluindo sete gramíneas e três leguminosas. Este experimento foi instalado e, 1977 e teve sua primeira avaliação feita durante o período seco de 1978 e esta...

Produtividade de Brachiaria decumbens STAPF cv. australiana em função de níveis de fósforo.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: SOARES, W. V.; SOUZA, O. C. de; CASAGRANDE, J. C.
Os solos sob vegetação de cerrado, predominantes no Brasil Central Agropecuário, apresentam-se geralmente com níveis muito baixos de fósforo e com alto poder de fixação deste elemento quando adicionado ao solo como fertilizante. Tal fato tem sido relatado como um dos fatores mais limitantes para o crescimento de plantas tradicionalmente cultivadas em outras regiões com solos mais férteis. Por outro lado, a B. decumbens vem sendo introduzida muito intensivamente na região apesar de não se ter ainda dados de pesquisa sobre as exigências nutricionais desta espécie e a capacidade dos solos de suprirem nutrientes para a mesma e em que espaço de tempo. Considerando o problema acima exposto, foi instalado em novembro de 1978, um experimento de parcelas com B....

Influência do Ferbam e do anelamento da haste clonal na enxertia da seringueira (Hevea spp.) na microrregião Alto Purus, AC.
Provedor de dados: Informação Tecnológica em Agricultura (Infoteca-e)
Autores: LINS, A. C. R.; CASTRO, F. de A.
A propagação da seringueira é geralmente feita por enxertia sendo mais empregado o método Forkert (tipo convencional) que consiste na inclusão da gema em "seedlings", porta enxertos de um ano de idade. Por este meio de propagação obtém-se seringais com uniformidade no desenvolvimento e na produção, diferindo portanto dos seringais nativos. Outras vantagens favorecidas pela técnica, seria a multiplicação vegetativa fácil, garantia do alto rendimento e resistência às enfermidades de interesse econômico. É recomendável, ainda, a utilização dos métodos borbulha de catáfilo, com a parte superior do escudo embutido, e borbulha da folha com a parte inferior do escudo embutido, ambos com fita plástica transparente, na prática da enxertia verde.

The fish reserves in the Arcachon basin are a semi-natural lagoon com­plex which are suitable for the analysis of various population dynamics problems. We will consider here the population of the shrimp Palacmonetea varians, an impor­tant link in the food chain between primary production, the production of meiofau­na and that of exploitable species, e. g. bass, eel. Estimations of biomass and abundance are extremely important when one studies the quantitative production of macrofauna in a lagoon system. The methodology utilized (net traps, tagging methods and stock assessment by simple or multiple capture and recapture techniques) is particulary suited to the conditions of the milieu. Our results confirm the im­portant role played by shrimp in the...

Upper cretaceous to quaternary sedimentary process in the bay of biscay from textural, mineralogical, and coarse fraction studies
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Auffret, Gérard-andré; Pastouret, Léo.
The evolution of the sedimentary regime that prevailed on the Armorican margin from Late Cretaceous to late Tertiary is herein discussed and interpreted. The sedimentation budget of four components of the sediment : calcium carbonate, quartz, "less than 10  m non carbonate material,"and biogenic silica are quantified as is the composition of the coarse fraction and the textural properties of the sediment. Variation of the coarse fraction components is directly related to change in the oceanic environment (terrigenous supplies, productivity, calcium carbonate dissolution). Sediment texture is a function of many factors, comprising lithology, dissolution action, and hydrodynamic control. The medians of the silt fractions from bulk and decalcified sediments...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Castaing, P; Allen, Gp; Houdart, Michel; Moign, Y.
The objective of this study, carried out in the Gironde estuary inlet, was to determine the nature of the seaward dispersion of estuarine water and suspended sediments during a spring tide and high river flow. On June 3, 19(7, three flights were made over the inlet, at mid ebb, low tide and mid flood. The planned flight at high tide was cancelled due to adverse meteorological conditions. During each flight, thermal infrared coverage was obtained, together with black and white photographs.

Wind induced upwellings in the gulf of lions
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Millot, Claude.
Continental shelf dynamics have been observed since 1974 in the Gulf of Lions (NorthWestern Mediterranean Sea), with the principal aim of understanding the sumrner circulation in this region. From satellite infrared data, current meters, thermistor chains, and tidal gauge records, it appears that the major events occurring on the continental shelf take the form of wind-induced mesoscale phenomena. These phenomena, which are connected with strong and transient coastal upwellings, are generated by NorthWesterly winds, the mistral and the tramontane, which are highly transient in speed, with a stable direction and a short lifetime. These specifie features have enabled us to investigate the transient response of the sea on about ten such occasions per typical...

Olfactory imprinting and homing in salmon
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hasler, A.
The olfactory hypothesis of the salmonids' "homing" assumes that the juvenile is conditioned to recognize a specific scent of its native river during the smolt stage and that it uses this characteristic to locate its river for upstream migration. We tested this hypothesis and exposed, in artificial conditions, some farmed coho salmon, rainbow trout and fario trout, aged 18 months, to a chemical (morpholine or alcoolphenetyl) introduced in the natural production environment (mixed with the scents of the native river), in order to determine if they will be responsive to this product to locate their initial production environment during upstream migration.

Utilisation des chaînes alimentaires naturelles et du recyclage des eaux usées dans la production à grande échelle de juvéniles pour l'aquaculture

The production of Juveniles, key of aquaculture, needs for the alimen­tation of the larvae, to dispose plankton preys, which cannot be supplied by rea­ring. The collections realised with adapted implements, have led to very po­sitive results In both types of media, situated in the surroundings of Séte : mar shes and oxydation ponds (used for waste water purifying). The most abundant plankton in these two kinds of media are uni-cellular algae, Rotlfera, Copepoda, Daphne (oxydation pont) and Aetemia (marshes). These populations constitute a complete alimentation sequence without an equivalent for the necessities of larvae and juveniles. Our qualitative collections (from 0,2 to 20 kg/h) plankton, dependent on the species) have allowed to rear, without any...

THE Sierra Leone Rise, located in the east equatorial Atlantic, forms a discontinuous chain of seamounts as shallow as 2 km extending with a general NE-SW trend from near the Sierra Leone Coast of Africa, to the St Paul fracture zone near the Mid-Atlantic Ridge (Fig. 1). The origin of this feature has remained a topic of discussion. Sheridan et al.  have hypothesised that the Sierra Leone Rise is a volcanic structure formed at the beginning of the opening of the Atlantic in the early Cretaceous period. [NOT CONTROLLED OCR]

Salmon Ranching in Iceland
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Isaksson, A.
Over the last thirty years, the catches of Atlantic salmon in Iceland gradually increased to reach 80 000 fishes in 1978. This increase is due to the possibility for the fishes to grow, to repopulation but also to the total prohibition of sea fishing, thus favouring the development of "sea-ranching". The "sea-ranching" projects conducted since 1963 have enabled return rates of 4-5 % with records of 10-15 %. [...]

Autores: Heral, Maurice; Woehrling, Daniel; Halgand, Daniel; Lassus, Patrick.
The "Bongo" net is an American plankton net whose use is coming into general use for studies of ichthyoplankton. Its dimensions and its power of filtration make it an efficient device for researching groups with unevenly spaced micro distribution as well as rare species, especially fish eggs and larvae. It is recommended by the ICNAF (Standard Techniques for Pelagic Fish Eggs and Larvae Surveys) and will soon be recommended by the FAO. The ISTPM, for its part, has been using this net for some years in several campaigns conducted by the Thalassa, the Cryos, La Pélagia, the Roselys and the Ichthys (ISTPM 1971, 1975, ALDEBERT 1975, ARBAULT and LACROIX 1975).

Numeration, biomass, distribution within time, some physiological characters and a taxonomical outline, with a standardized micro method, of aerobic hétérotrophie bacteria isolated from sediments an waters, from fishponds of "Domaine de Certes" (Arcachon) from june 1977 to may 1978 are described. Number of hétérotrophie bacteria evolved in a significant way, according to seasons, and bacterial biomass is higher in the sediments than in the waters. Metabolic or physiological differences (proteolysis, denitrification) appeared among populations due to the origin of sediments. Moreover the qualitative study pointed out taxonomical units as Bacillus associated to seasons, or Agrobacterium associated to vegetable detritical sediments.

Impact of artifical propagation of salmon on the pacific coast of the United States and Canada 1872 - 1979
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Wahle, R.
Before the 1960s, the repopulation projects almost did not succeed in increasing the Pacific salmon fisheries production. Later, thanks to some research programs focusing on the development of fisheries in the Columbia River, artificial production played an important role in maintaining the sea and river salmon fisheries. Today, about 50 % of the chinook (Oncorhynchus tshawytscha) and coho (Oncorhynchus kisutch) salmon, as well as sea trout (Salmo gairdneri) caught on the Pacific coast comes from the production of farm smolts. The current research should help to increase this contribution.

The boundaries of territorial waters are not as stable as boundaries on land. Nowadays, indeed they are characterised by their very mobility. No doubt the reason for this is political. A state which sought to further her own interests by enlarging her domain within her own waters would encounter no sovereign opposition. Additonally, with the collapse of the traditional "understanding" regarding the conception of -and the criteria governing -maritime boundaries. nations chose the most effective methods of appeasing their own needs and appetites. This was achieved with the maximum ingenuity. The natural boundary myth was shaken sometimes before and sometimes simultaneously with, the cultivation of negotiating skills or, from a position of strength. the...

Whole-rock geochemical data were obtained for 178 samples selected from the petrologically freshest parts of most of the flow units recovered from the nine holes. These data include 170 major element analyses (XRF) and 174 trace-element analyses (XRF and INAA). We include representative microprobe analyses of the primary minerals and fresh basaltic glasses (where present) in 40 selected samples. We also present 87Sr/88Sr ratios for 14 samples selected from the holes at 63"N. These analytical data, together with petrographic data obtained from the study of some 500 thin sections, have enabled us to establish a detailed lithostratigraphy for each basement section.

Autores: Bressolier, Catherine.
Pointe de la Coubre spit, located to the N of the Gironde estuary, is rapidly evoluting under particularly efficient wave and wind actions. Morphological evolution between 1973 an 1977 is described : the ultimate state of evolution is going to be reached :  longshore bars and channels system is extending, diminishing upper beach slopes. The distal part of the spit is notably accreting, a beach barrier is forming, both tending to obturate Bonne Anse channel. In Bonne Anse lagoon, mud deposition processes, more efficient than transport and suspension ones, are enhanced by sand accumulation on spit neighbouring. Dunes seem to be stable, although vegetation tends to trap sands especially on distal part.

Changes on the coastline of southwest england - a review
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: May, V.j.
During the last hundred years, progradation was uncommon in that area. It had only minimal association with cliff erosion. It concerned mainly the free distal ends of sand and shingle spits, the artificial constructions which interrupt longshore sediment transport, and was related in Cornwall with deposition of china clay spoil.

Autores: Sibuet, Jean-claude; Ryan, William B.f.; Gustafson, Ted B.; Smith, S.m.
The scientific party aboard Glomar Challenger collected geophysical data during DSDP Leg 47B, which commenced from Vigo, Spain, and terminated at Brest, France (Figure 1). Site 398 (40°57.6'N, 10°43.1'W), located just south of Vigo Seamount and about 95 miles West of Porto, Portugal, was drilled from 13 April 1976 to 9 May 1976. Table 1 gives satellite positions, distance (in nautical miles along the track) and the speed and course between successive navigation points. The positioning error along the trackline is approximately 1 nautical mile. Distances are shown (Figure 1) along the trackline every 50 nautical miles and annotated every 100 nautical miles. Time is marked by crosses every 2 hours and annotated every 4 hours. [NOT CONTROLLED OCR]

One of the criteria for selecting a shrimp of commercial interest in French Polynesia is the acceptability of artificial diet; such a criterion has been used to test Penaeus merguiensis.Experiments have been carried out in Centre Océanologique du Pacifique in Tahiti island where the water temperature range is 25-29°C, salinity 35 ppt, pH. 8.2, and photoperiod constant.Juveniles used in this study are hatched in CNEXO-COP at Vairao.It has been found that a 50-55% protein content diet gives a better growth performance. A carbohydrate such as starch appears more suitable than glucose or glucose plus starch in isonitrogenous purified diets.A vitamin mix rich in vitamin C, choline and inositol provides better results and a mineral mix with 3% magnesium reaches...

Inventaire des ressources halieutiques et conchylicoles de la Manche

Autores: Lemoine, M.
La Manche peut être considérée comme une région de transition d'une part entre les pêcheries de Mer du Nord et des accores de l'ouest, d'autre part entre les grands ports de pêche à caractère industriel de Boulogne et du Finistère sud. Cette particularité fait souvent oublier que cette mer a toujours été le théatre d'activités de pêche importantes et variées. Il a paru nécessaire, avant d'entreprendre l'inventaire de ses ressources halieutiques et conchylicoles, de situer la Manche en tant que zone de pêche à considérer à deux titres: en tant que zone de pêche internationale donnant matière à d'importantes pêches industrielles saisonnières, en tant que zone très exploitée par les flottilles d'artisans des pays riverains.

Chemical and Biological evolution of sediments in closed circuit : I. Nitrogen and bacteria. A series of well controlled sea water closed circuit sand filters al­lowed the study of chemical and biological regulation processes in the sediment. Bacteria, Nitrogen chemistry and meiofauna were mainly investigated. The evolution of the different forms of nitrogen is rather similar, whatever the organic matter flow in the sediment. As long as the amount of or­ganic input works as limiting factor, bacteria densities are proportional to its flow. No correlation was found between bacteria and chemical parameters in the sand or in the water. The temperature does not seem to play a determinant part neither in the evolution of bacteria nor in the mineralization of...

Première approche de la dynamique d'une population de Temora Longicornis O.F. Müler (Copepoda, Calanoida) dans les bassins à flot du port de Dunkerque (France)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Brylinski, Jm.
The wet docks of Dunkirk are 3 to 4 degrees Celcius warmer than the seaboard waters of the North Sea. Such warmth is due to thermic industrial was­te mainly from the E.D.F. power-station. A thermic and saline stratification can be observed that favours heterogeneousness among the populations of Temora lon- gicomis. The samples of copepods taken from the North Sea are significantly bigger than those found in the port of Dunkirk. Differences in size vary in the course of the year. The action of high temperatures upon reproduction is being debated j so is the existence of an autochtonous population in the docks in sum­mer.

Thermal regime of the northern bay of biscay continental margin in the vicinity of DSDP sites 400 to 402
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sibuet, Jean-claude; Foucher, Jean-paul.
Ten conventional oceanic surface heat flow measurements were made over the northern margin of the Bay of Biscay in the vicinity of the DSDP Sites 400 to 402 during the R/V Suroit - SU 01 (December 1975) and R/v Jean Charcot - CH 66 (February 1976) cruises of CNEXO. These measurements, complemented by the heat flow determination made at Site 402 during Leg 48 of the Deep Sea Drilling Project (Erickson et al; this volume) provide information on the thermal regime of the margin.The main observation is that the regional heat flux over the margin is substantially lower than over the adjacent Western European continental area.We suggest in this report that the observed heat flux contrast provides constraints on the debatable nature of the crustal thinning...

Chemical and Biological evolution of sediments in closed circuit : II. Effect of soluble organic matter input on meiofauna in poly­trophic systems. The effect on meiofauna of the input of soluble organic matter in clo­sed circuit sand filters was followed during two years for an oligotrophic, a mesotrophic and an eutrophic tank, and during one year for an atrophic tank. In the case of no input, the density, biomass and species richness of nematodes decreases even if equitability remains constant. Oligotrophy main­tains the stability and diversity. Mesotrophy changes the community composition by species succession. Eutrophy allows biomass increase, due to one dominant species.

Autores: Alayse, J.p.; Lahaye, J.
The experimental unit used previously in our laboratory for the study of the effect of the photoperiod on the growth of flatfish was based on the use of tanks with separate recirculation systems. We modified it, connecting the different tanks to a single, more powerful recirculation system. This new unit comprised four different parts s - a biological filtar and an ultraviolet sterilizer. - a gravity operated water distribution system. - a series of 12 rearing tanks. - a piping system connecting the tank outlets to the biological filter. The total volume of the unit was 8 900 l. 200 l were changed every week. The main advantages of this new unit was that the quality of the water supplied to all tanks could be exactly the same, and that various parameters...

Influence of deep water circulation and sea floor morphology on the abundance and grade of central south pacific manganese nodules
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Pautot, Guy; Melguen, Marthe.
Analyses of polymetallic nodules from the central south Pacific and from the underlying sediments indicate that nodule abundance is at least partly related to the degree of carbonate dissolution, which, it self, is strongly influenced by the flow o f the Antarctic Bottom Water. The greatest nodule abundance is generally encountered in a 300 to 400 meter thick water layer situated between the lysocline and the calcite compensation depth levels.This range of depth is the first and main controlling factor of abundance. Inside this range, the bathymetry represents a secondary factor influencing both abundance and grade.Some correlations appear locally between nodule grade and abundance.Nodule grade seems to be generally related to the bottom morphology.

Such a program implied to spawn the adults , to hatch the eggs, to rear the larvae, and to wean the juveniles ont0 an inert diet that would support their growth up to the commercial size , for all of which facilities had to be built , and knowledge had to be acquired. In order to facilitate the comparisons, all the larvae were reared at temperatures close to 18° C. In such conditions, the weaning to the inert diet could be achieved before the fish were 3 month old. The work...

Flux de pollution au littoral cauchois
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Dupont, J.p.; Peltier, J.c.; Hommeril, P.
Initialement cette étude devait avoir pour but de définir et quantifier les flux polluants pouvant affecter le littoral cauchois. Cet objectif a été partiellement abandonné. L'optique de ce présent travail est quelque peu différente. Dans une première partie nous abordons le problème de la dispersion des flux polluants afin de tenter de définir les zones les plus sensibles de notre littoral. Pour ce faire, nous avons procédé à des missions aériennes photographiques. Le traitement des images obtenues révèle le devenir des flux continentaux au flot et au jusant.

Application de la Fluorescence X à la détermination analytique d'éléments trace dans les roches et les verres fluorés.
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Corre, Odile.
Parmi les différentes méthodes physiques d'analyse, la fluorescence X occupe une place importante en raison de la diversité de ses applications et de la possibilité qu'elle offre d'analyser des échantillons de façon non destructive. Jusqu'ici cependant, la mesure de "faibles concentrations" a été moins développée du fait de l'impossibilité de mesurer des intensités de fluorescence à partir de solutions tampon vis-à-vis de l'effet de matrice.

L'évolution de la maladie de la glande digestive de l'huître plate dans le bassin d'Arcachon et ses conséquences actuelles
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Tige, Gilbert; His, Edouard; Rabouin, Marie-agnès.
Nous avions montré qu'en 1975 la maladie de la glande digestive de l'huître plate était responsable d'une mauvaise qualité et de mortalités importantes d'huîtres plates du bassin d'Arcachon (His &amp; coll., 1976). L'étude des populations autochtones, captées successivement au cours des étés de 1974, 1975 et 1977 a été entreprise de mai 1977 à Janvier 1979. La croissance des huîtres redevient satisfaisantes ces dernières années; la qualité des mollusques s'améliore; les mortalités sont peut importantes. Le phénomène est plus sensible chez les populations les plus jeunes. Parallèlement nous notons une régression de la parasitose, tant au niveau des taux que des intensités de l'infestation.

Evolution de communautés phytoplanctoniques après fertilisation modérée
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Jacques, G.; De Billy, G.
One approach to the problem of aquaculture consists in a simple acceleration of natural processes in extended areas of salt or brackish water. From this point of view, the authors have been in­terested in the effect of moderate fertilization on natural communi­ties . A first series of experiments (8) was made in an exter­nal tank of 3000 liters. After fertilization, the development of flowering diatoms was obtained each time. The time of latency, the level of production reached, the composition of the final communities is to some extent variable, but bacterial development may be neglec­ted. In contrast to earlier results, obtained in small volumes of water, these experiments have always led to simplified communities mostly dominated by the diatom...

Comparaison de trois index de qualité de l'huître creuse Crassostrea gigas
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Berthome, Jean-paul; Deslous-paoli, Jean-marc; Fernandez-castro, N.
Three indexes of quality of Japanese oyster Crassostrea gigas were studied in 3 lots of oysters bred in the r.1arennes-oléron basin from february to july 1979: condition index of MEDCOF &amp;-. NEEDLER,  thickness coefficient of IMAI &amp; SAKAI and external quality coefficient of BERTHOME. These different indexes were correlated within each lot of oysters. The external quality coefficient is always significantly correlated with condition index, while thickness coefficient is correlated with other two only for one lot, but seemes useful to rate oyster growth better.

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Cahet, G.; Martin, Y.
An experimental eutrophication carried out with several technics on mediterranean sea water (Embiez) in autumn shows : - significant variations in the electro-chemical composi­tion of phytoplanktonic excretion; complex organic substances are excreted during two different periods, especially after the Skeletonema costatum bloom; - close relations between heterotrophy (l4C glucose test) and excretion of organic matter by photosyn­thetic organisms, glucids are always predominant; - the original heterotrophy from the 14c pyruvate test; which is obviously more selective than the 14c glucose test; - the existence of different periods of active ultraplankton.

Autores: Michel, Pierre; Grizel, Henri.
La présente étude n'est pas limitée dans le temps à la durée de la convention de recherche qui lui est propre. En effet, le suivi de la contamination des huîtres touchées par l'"Amoco-Cadiz" a débuté aussitôt après l'échouage du pétrolier en mars 1978, supporté par le contrat C.N.E.X.O. 78/5719. On ne peut dissocier du point de vue scientifique ce qui s'est passé dans l'année qui a suivi l'échouage et ce qui s'est passé après. Nous reprenons donc ici le bilan global des essais et mesures que nous avons effectués sur les huîtres en 1978 et 1979. Des travaux spécifiques, portant sur les huîtres, sont mis en place rapidement. Ils visent, outre l'intérêt scientifique indéniable qu'ils représentent, à répondre aux problèmes pratiques soulevés par les...

Chromatiaceae are unceasing present in the sediment of Certes's lagoons. The genera isolated ares Thiocapsa (80%),Chromatium and Ectothio- rhodospira. From august to October 1977, physical-chemical and bacteriological analysis, in red water present in lagoons, show the Chromatiaceae proliferation and presence of hydrogen sulfide. In October 1977, a study of white water development display the absence of sulphurbacteria and the presence of hydrogen sulfide,carbon dioxide and carbonate. The important role of photo­trophic bacteria in the sulphur cycle are demonstrated by comparison between these waters.

Autores: Nival, Paul; Malara, G.
Choosing the best conditions for the cultivation of plankton in tanks is a difficult deal, which is generally solved by means of subjective estimations. A better way of looking for these conditions is the use of a mathematical model. _ We have tried to built a model that accounts for the physical and bio­logical characteristics of the tanks. The data concerning the physiological characteristics of the different group of organisms encountered are too scarce to allow all of them to be taken into account. The system studied here is composed of nutrients, phytoplankton, herbivorous copepods and rotifers to which benthic algae have been added. With the hypothesis of 3 elements (phyto - zooplankton - nutrients) it can be showed that when an equilibrium is...

The existence of a Haplosporidie parasite in the clam Tapes deucussatus has been demonstrated by Vilela (1950) with the description, based on classical histology observations, of a new species: Haplosporidium tapetis Vilela. Recently, the examination of the histological sections of the digestive glands of some clams from the Thau lagoon helped the scientists to find, in the stomachal epithelium, some forms comparable to the plasmodium of H. tapetis and to precise their ultrastructure.

Plongées en submersible dans les canyons méditerranéens : principaux résultats de la campagne Cyaligure

Autores: Bellaiche, Gilbert; Rehault, Jean-pierre; Vanney, Jean-rené; Auzende, Jean-marie; Courmes, Francis; Irr, France; Roure, François.
The observations carried out during the "Cyaligure" submersible cruise emphasize the shaping action of the submarine currents and slidings during the Quaternary. The canyons located off the french Riviera (Provence), cut in late Oligocene detrital formations, have been the locus of several phases of in-filling, lithification and cutting phenomena throughout the Messinian epoch up to now. Consequently they can be considered as complex polygenetic structures. The canyons located off SW Corsica appear to be directly cut, in their upper course either in the cristalline basement or in volcanic lava formations. In their median part, they are cut in quaternary sediments and in their lower part in middle or late Miocene sedimentary units. The strong linear NW-SE...

Feeding problems and the technology of rearing marine fish larvae
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Girin, Michel.
The production of marine fish fry is presently based on the use of live food organisms, at least during the first few weeks after hatching. As outdoor pond techniques, with natural production of live food organisms, could never be very successfully applied to marine larvae, the food organisms used are either cultured or bought at a high price on a speciaiized market. Cutting down the cost of the production of fry implies cheaper live food organisms and early weaning techniques, but the most promising solution for the future would undoubtedly be the use of artificial diets straight from first feeding. It has been demonstrated on some species that the larvae can survive on such diets, but important technological problems still have to be overcome before they...

Autores: Grizel, Henri.
The parasite responsible for the disease of the flat oyster, Ostrea edulis has been the object of numerous studies (Comps 1970), (Tigé and Morel, 1974, Perkins, 1976) in which most considered the internal cycle of development of the parasite in the oyster, and the parasite's structure, ultrastructure, and systematic position, of which the latter remains debatable. In this paper I mention observations made at the time of diagnosis for the presence of infections and information gained through studies of oysters on the bottoms of estuaries and coastal waters. The research is designed to provide practical solutions to problems facing oyster culture.

Evolution des caractéristiques chimiques et biologiques des sédiments en circuit clos. IV. Régulation du nitrite en présence de crevettes Penaeus japonicus
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Mevel, Genevieve.
Prawns (Panaeus japonicus) were rearing during more than nine months in experimental closed circuit tanks. In such systems the nitrite appearance is related to the normal nitrification process and to oxygen deficiency. Above a given level, nitrite causes the death of prawns. The soluble oxygen concentration and, thus, nitrite level in the water appears as the main factor for a successful development of prawns in closed circuit tanks. In these conditions, the growth rate of the prawns is relatively low (9g/per individual in seven months). Never theless, such a system allows a load of some 600 g prawns per m2.

Perspectives de développement régional : la Baie de Saint Brieuc
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Nicolas, R; Morize, E; Rohan, R.
The application of a model of stock management is difficult because the imperatives of longterm development are often conflicting with short-term interests of the fishermen. That has been the reason for setting up a field group under the responsability of the Comitéd'Expansion des Côtes-du-Nord.   The document presents two examples of these difflculties to apply the biological results. The first concerns the management of the existing ressources with the limitation of fishing eflort, the establishment of a catch quota and a non fishing area. The second describes the natural spat collection system adapted to the local environment which has to produce a significant number of juveniles for restocking purpose.

Campagne CYAGOR - Submersible Cyana - 25 juillet-26 août 1977
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Le Lann, Alain; Auzende, Jean-marie; Olivet, Jean-louis.
We present in this paper raw data and preliminary results of CYAGOR dives (July-August 1977) on Gorringe bank (SW Portugal). A series of eight dives with submersible SP 3000 Cyana, from 2 600 to 40 m depth, enabled us to observe the outcrop of the bank flanks, a nearly complete cross-section of oceanic crust and upper mantle. The structure seems to be little affected by fracturing and is slightly rocked to the NE. Cross-sections made during the dives show characteristics similar to those of an ophiolitic complex.

En ce qui concerne les sites de PLOUMOGUER et PLOGOFF, le Centre National pour l'Exploitation des Oceans (C.N.E.X.0.) a sous-traite A l'Université de Bretagne Occidentale (U.B.0.) la réalisation de la plus grande partie des études écologiques d'avant-projet, qui n'ont porte dans un premier temps que sur les problèmes relatifs au benthos (faune et flore du fond). Une synthèse (ALLEN et al., 1978) des résultats obtenus lors des études d'avant-projet des sites bretons a fait apparaître que l'absence, sur ces deux sites, de résultats concernant le pelagos (faune et flore de pleine eau) était une lacune grave qui devait être comblée avant toute décision définitive.

Adaptation des Echinodermes à la vie abyssale
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sibuet, Myriam.
The synthesis of literature and personal observations permitted to show the main morphological physiological and genetic characteristics with relation to the mode of life of abyssal echinoderms. The large ventral sole is common among holothuroids and asteroids which creep on the bottom. The development of large podia and their ability to swim are particular to the abyssal family Elasipoda (Holothurioidea). The paper gives examples of opposite skeleton constitution either heavily or lightly calcified. The little knowledge about the biology of these animals shows the absence of a strict diet and of a particular mode of reproduction. [NOT CONTROLLED OCR]

Autores: Beurier, J. P.
The access to the stocks of fish is determined by the restriction of the freedom of fishing prescribed by the coastal state with the concept of exclusive economic zone. that is to Say that the biological resources of the coastal sea will belong to the coastal state. This state has to respect the conservation of fisheries to prevent stocks from overfishing. The 1958 Geneva Convention settled a global regulation of conservation. Actually it is insufficient. Developing countries find a fault with this fact, and promote a regulation power for the only coastal state. An agreement could succeed between coastal states and fishing states only in the frame of a regional exploitation of resources. This regionalism is the topic concept of the future law of the sea of...

This these is the result of several years of investigations conducted on the common prawn Palaemon serratus in the Roscoff (northern Brittany) and Yeu (bay of Biscay) sectors of the French Atlantic coast.    Following a description of the fishery and fishing strategies, it deals with the species biological aspects, focusing on growth, lifespan, sex-ratio and breeding. Hypotheses on the reasons for apparent variations in interannual abundance are drawn up and compared with field observations.   The second part is devoted to production experiments in a controlled environment (hatchery), explaining how larvae are obtained and their development and survival with respect to food, density and physical parameters like salinity and temperature. The link between...

Intensive larval culture of Macrobrachium rosenbergii : a cost study
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: AQUACOP.
Pilot scale larval culture of Macrobrachium rosenbergii began in Tahiti at the end of 1976. Since then, four batches of postlarvae (2.3 millions) have been produced. Operating expenses cost was $13-35/thousands postlarvae. Based on the results obtained from the pilot program, we can project the cost of a commercial scale hatchery producing 10 million postlarvae/ year at $12/1,000. This includes construction and equipment costs. Due to the high cost of living in Tahiti, this figure would undoubtedly be lower in many other regions. [NOT CONTROLLED OCR]

Les phénomènes étudiés sont provoqués par l'enrichissement en matière organique, des sédiments et de l'interface eau-sédiment. Cet excès de matière organique bénéfique à faible concentration est néfaste ensuite. Nous avons défini les différents stades de la dégradation du milieu et établi le parallèle entre la Rade de Brest et d'autres milieux benthiques pollués dans le monde.

Autores: Bodoy, Alain; Masse, H.
Some parameters measuring the production of organic matter, in field conditions, by a population of the bivalve mollusc Donax trunculus have been stu­died. Those studies which are easily done when the population is composed of long lived species become difficult in Mediterranean Sea where the populations are instable and composed of short-lived species. A large qualitative sample has been made every month on which the inter­pretation of cohort succession has been done using the graphical method of CASSIE (1954) which is an useful mean to determine the modal class-size. The monthly values of the weight/size relationship, during a year, show important fluctuations indicating that size increment, tissue weight increment, gamet production and release are often...

This study quantifies the influence of temperature on the respiratory activity of juvenile Dicentrarchus labrax L. The fry were less than one year old and were obtained from the breeding tanks at the C.O.B. (Centre Océanologique de Bretagne). Diminution in the oxygen concentration, during time, within sealed ves­sels was measured with a Clark oxygen electrode (Orbisphere Material modified). Initially the respiratory rate was determined, for acclimatized fishes, as a function of the decrease in the oxygen concentration of the milieu at diffe­rent temperatures (8°, 10°, 15°, 20° and 25°C) and constant salinity 30 %o . The relationship between metabolism and weight, at these temperatures was then established for two different levels of activity "routine" and...

Autores: Dumas, J; Prouzet, P; Porcher, J.p.; Davaine, P.
At present, there are no more than 30 salmon rivers in France located mainly in Brittany, lower Normandy, Loire-Allier basin and Adour-Gave Basin. The depletion of salmon populations has been general and more pronounced for the last years (less thant 5.000 fish captured per year since 1973). The main causes of this depletion are : dams without fish ways, new causes of variation of flow, pollutions, overfishing either in rivers or in the sea (Greenlandsea). In France, Atlantic salmon have a short fresh water life span (mainly 1 or 2 years old smolts). They grow very fast (16 to 18 cm at 1 year and 20-22 cm at two years) and they migrate to the sea mainly in April. The majority of the exploited population spends 2 years or more in the sea, and runs in winter...

Observations of peculiar volcanic objects, made by a submersible on the deep sea floor at a depth of about 2.600 m at and near the axis of the East Pacific Rise during the CYAMEX expedition as part of the RITA Project are presented here. Two basic types of flow forms were observed within the crestal area of the East Pacitic Rise : pillow flows and fluid lavas, the latter sometimes overlying massive flows. The East Pacific Rise at 21°N comprises an axial, unfaulted extrusion zone bordered by an extension zone chararterised by faulting. Pillow flows occupy the innermost or extrusion zone and constitute small elongated volcanic highs. [NOT CONTROLLED OCR]

The japanese palourde Venerupis semidecussata was reared in the Bay of Brest, using hatchery reared spat. Experiments were performed with individuals of lenght 2 to 10 mm raised in a nursery, using raceways with slow running water enriched with unicellular algae, And also with individuals of lenght 8 to 20 mm raised at sea in suspended culture. It was observed that growth depends upon four groups of factors : (1) the functioning and equipment of the raceways, (2) the quantity and quality of the food, (3) the temperature and (4) various physico-chemical factors. When the equipment is satisfactory and when the physico-chemical fac­tors are normal for the species in question, the rate of growth depends essen­tially on the quantity of food, provided that the...

Alteration, fractional crystallization, partial melting, mantle properties from trace elements in basalts recovered in the north atlantic
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bougault, Henri; Joron, Jean-louis; Treuil, Michel.
.-Alkali metals prove to be very sensitive to alteration process even if this process is moderate. It is very difficult to use these elements to trace magmatic processes since their concentration may Vary within an homogeneous "unaltered" unit. From all the basaltic units investigated, a classification of "low partition coefficient" elements is presented (Sc, Ti, V, Y, Zr, Nb, La-Tb , Hf, Ta, Th) . The incompatible elements ratios (Y/Tb, Zr/Hf, Nb/Ta) are constant in the samples studied and are nearly equal to the same ratios in chondrites. This is consistent with the existence of an homogeneous primordial mantle at the scale of the North Atlantic, compatible with a chondritic composition of the earth. [NOT CONTROLLED OCR]

Autores: Le Borgne, Y.
The early life stages of the growth of bivalve molluscs being now controlled, at least for oysters and clams, it is possible to obtain seeds in large amounts and at given times. Reproduction may be obtained at any period of the year and the survival rates range from 5 to 50 % these values being considerable compared to those of natural reproduction in the sea.   However the cost of the spat increases very sharply with size because of energy input (heating, pumping and phytoplancton production).

DSDP Site 398 is located on the West Iberian passive continental margin, south of Galicia Bank, 20 km to the south of Vigo Seamount (Figure 1).The kinematic evolution of the Iberian plate is closely controlled by the relative motions of the African, European, and North American plates. A study based on magnetic data and land data was undertaken to better define the relative motion of Iberia with respect to these main plates (Sibuet et al; in preparation).Trapped between these plates, microcontinents such as Galicia Bank and Flemish Cap (located between Iberia and North America) assumed their own relative motions with respect to Iberia and North America during the early evolution of the North Atlantic.Consequently, the initial oceanic circulation between...

Autores: Antoine, Loic.
L'étude de la dynamique des populations est une discipline qui cherche a cerner les mécanismes de régulation et d'évolution des stocks ; appliquées aux espèces marines exploitées, elle cherche a évaluer les stocks ainsi que l'effet de l'exploitation sur la dynamique, dans le but pratique d'aménager rationnellement l'exploitation.

Salmon ranching in oregon
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Mc Neil, William.
The Oregon State has authorized twelve private firms to release 180 million Coho, Chinook and Chum salmon juveniles in the framework of several sea ranching operations. Including the release of juveniles from State hatcheries, the total future production should reach 258 million. In 1978, this production was of about 84 million salmon juveniles. The Oregon State currently contributes to about 3 % of the total amount of salmon juveniles produced artificially and released in the northern Pacific Ocean. We reckon that the rise of the sea ranching activity in the Oregon State goes hand in hand with a rise in other states or countries, and the future plans for Oregon are to keep contributing to about 3 % of the production.

Autores: Buestel, Dominique; Nicolas, R.; Morize, E.; Rohan, R.; Latrouite, Daniel; Le Borgne, Y.; Cochard, Jean-claude; Flassch, Jean-pierre; Uno, Yutaka; Audouin, Jacques; Legall, J.y.; Jezequel, M.; Lorec, J.; Henocque, Yves; Reveche, C.; Girin, Michel; Laurec, Alain; Herry, P.
L'aquaculture extensive et le repeuplement sont deux modes d'exploitation des ressources halieutiques qui ne font appel, une fois les juvéniles produits, ni à un apport de nourriture artificielle, ni à un contrôle continu de la part de l'exploitant, mais dépendent par contre de la productivité du milieu marin, Cette approche repose sur l'idée que le principal facteur limitant d'une population naturelle est le faible nombre de survivants après les premiers stades, et que l'on peut par alevinage, aménagement du milieu ou autres techniques, augmenter la production d'une espèce exploitable, Le but de ces journées d'étude est de faire le point des connaissances sur ces sujets, à l'intention des scientifiques mais aussi des utilisateurs, Il a paru souhaitable de...

Etude des structures démographiques des captures d'Ammodytidae (Lançons) de la côte est du Cotentin
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Kopp, Joël; Joly, J.f.
Au moment où l'étude du milieu littoral prend une importance de plus en plus grande, il est apparu que nos connaissances sur les espèces caractéristiques de cette frange côtière souffraient d'une importante lacune. Aucune étude précise, par exemple, n'avait jamais été entreprise sur les Ammodytidae. Or tout le monde s'accorde à dire que, si ces espèces ne sont pas d'un grand intérêt économique direct, leur importance trophique pour des poissons de forte valeur commerciale (turbot, bar, morue, etc.) est, elle, bien supérieure. Il est donc apparu nécessaire de cerner avec plus de précision l'intensité de l'effort de pêche d'autant que les professionnels ont récemment demandé des dérogations en ce qui concerne le maillage des culs de chalut.

Autores: Desbruyeres, Daniel.
A new Ampharetid (Polychaeta, Sedentaria) has been collected in the deep sea during the French-Swedish Expedition NORBI in the east-Groenland basin. It represents the type of a new genus, Melythasides gen. nov., characterized by two modified setigerous segments, three pairs of gills, twelve uncinigerous thoracic segments and thoracic uncini with 5-6 series of teeth. The addition of another genera with one or several modified thoracic segments leads to a reconsideration of the taxonomic importance of this character. [NOT CONTROLLED OCR]

Note sur l'utilisation des traceurs radioactifs en écologie aquatique
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Pages, J.; Lemasson, L.
Lors des études de cinétique d'assimilation d'un substrat au moyen de traceurs radioactifs, certaines hypothèses sont généralement faites : flux liné­aires, traceur incorporé linéairement en fonction du temps, etc.; ces hypothèses sont examinées ici. A partir de données expérimentales, deux modèles possibles sont proposés. Le premier, simple, ne considère que le cas de la photosynthèse et n'est acceptable qu'en introduisant une énergie lumineuse variable. Le second, plus général, pourrait être applicable aux processus autotrophes et hétérotrophes; il est utilisé pour examiner les difficultés de détermination des constantes cinétiques (Vm et Kg); il est d'autre part illustré par quelques exemples expé­rimentaux .

Autores: Berthome, Jean-paul; Razet, Daniel; Garnier, Jacqueline.
The detection of larval oysters emissions and their evolution were studied in 1977 and 1978 and compared within two areas of the Marennes Oleron basin: The Seudre river and the northern part of the basin. In 1977, the earlier fication of spat were noted as soon as July 14th in both areas while in 1978, it had been necessary to wait till the end of August to see the beginning of settling. Hydrobiological datas were correlated one with others, as well as with quantites results of 1978 provide us with correlations indicating the importance of continental inputs.

Infections virales chez les huîtres Crassostrea angulata Lmk. et Crassostrea gigas Th.
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Comps, Michel; Duthoit, Jean-louis.
Two viral infections associated to some epizooties have been observed in Crassostrea angulata Lmk. The first one concerns the Gill disease in which the viral damages go hand in hand with a cellular hypertrophy, while, in the second one, the contaminated cells are associated with a deterioration of the connective tissue. These branchial necrosis associated to a virus have been observed again recently in some Portuguese oysters from the natural deposits of the Cadix (Spain) area. Moreover, the study of the summer mortalities (July 1977) in the oyster Crassostrea gigas Th. demonstrated the presence in this species of a virus of the same type as the one associated to the massive mortalities of the Portuguese oyster. In both cases, the viral morphogenesis takes...

Magnetism of the mid-atlantic ridge near 37°N from famous and dsdp results : a review
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Prevot, Michel; Lecaille, Alain; Hekinian, Roger.
Comparison of magnetic properties of pillow basalts from the Rift Valley (FAMOUS area) and from the Crest Mountains (site 332 of DSDP Leg 37) of the Mid-Atlantic Ridge near 37°N shows that major differences in magnetic structure and properties of the oceanic crust occur between these two sites. Mean effective intensity of magnetization of the pillow basalt layer drops from 1.4 x 10 ² emu cm   (4 A m  ) at the axis to about 0.4 x 10 ² emu cm   (4 A m   at site 332). While the magnetic anomaly over the spreading center may be accounted for by a magnetized layer less than 500 m thick, deeper seated material contributes to the magnetic anomalies over the Crest Mountains.

Les fonds de pêche sur la bordure caraïbe de la Martinique - Exploitation actuelle, première prospection
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Saint-felix, Christian.
Jusqu'à 1974, il n'existait pas pour le département de la Martinique d'études approfondies sur les ressources halieutiques de ses côtes, notamment en ce qui concerne leur potentialité, leur cartographie et leur niveau d'exploitation. L'Institut des Pêches maritimes a donc tenté de satisfaire ce besoin et c'est ainsi qu'un programme de prospections systématiques a été mis à l'étude. Les premiers résultats qui concernaient la partie centrale et orientale du littoral atlantique, ont été publiés en 1975 (Science et Pêche, n° 251). Dans le présent rapport, deuxième étape de cette série de recherches, il a été choisi de présenter non seulement les résultats de la prospection de la frange côtière caraïbe, mais aussi le niveau actuel de son exploitation.

Aquaculture extensive de la coquille Saint-Jacques : Résultats d'un semis expérimental
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Buestel, Dominique; Dao, Jean-claude.
Two main conditions are necessary for the extensive culture of king scallop: 1.The getting of spats, 2.A good survival rate for these spats in their natural environment. These two criteria enable the definition of the technical standards giving way to an economic analysis. Until now, the only solution to a juvenile production is their collection in their natural environment, on high adult density deposits. At the time being, out of all the French deposits, that of Saint-Brieuc is the only one answering this characteristic. However, even in this case, spat collection has not yet reached the necessary reliability. Indeed, the amount of spat collected for a year will rely on two main factors: 1.The state of the brood stock, 2.The climatic conditions.

Autores: Lee, Tae-won.
The fishing by the sluice, employed in the brackish fish ponds of Arcachon Bay, catchs only the migrating eels. The exploitation by this process is not more than the 18 percent of the biomass. The structure of the migrating eels caught in winter 1977-78 was estimated using the double sampling method with length as strata. The sex­ratio was about 1.1. The males migrate to the sea from 3 to 7 years after of the brackish water life (maximum 5 years old) and the females leave the fish ponds, generally from 5 to 9 years after (maximum 7 years old). The estimated mean lengths, 37.5 cm for the males and 49.8 cm for the females, were much smaller than-those which were estimated in the Italian "Vallis"

It is a long mass of luminous tissue with a pretty irregular outline, orientated more or less sideways on to the edge of the mandible (fig. 1). This photophore is located on the posterior external side of this bone roughly where the edges of the two supramaxillas cover up. We named it maxilla organ (organe maxillaire) and gave it the following abbreviation MXO. (unverified OCR)

The qualitative and quantitative evolution of a zooplanktonic population growing in a concrete tank after enrichment and production of a phytoplanktonic bloom has been followed during a time exceeding six weeks. After an initial unsteady period and a temporary peak of rotiferas, a progressive increase of organism abundance was observed, with a corresponding re­duction of their specific diversity. During the last phase of the experiment, the zooplankton community was qualitatively similar with the populations described in harbour waters or other semi-closed or closed marine spaces characterized by eutrophy and pollution. It was chiefly composed of copepods from Acartia, Tisbe and Oithona generas. The numerical density of organisms was,to a great...

Through the log-books of fishermen an estimation of the annual variability of recruitment (by annual first commercial size-class strengh) in a coastal lobster fishery has been realized for five fishing season (1973 to 1978). For this feature, year 1975 appears as an exceptionnal lobster season for the whole fishery along Brittany Coast, considering the apparent abundance of the recruits. The sharing out of the catches in commercial size-groups for this small fishery allows to estimate the minimal number of surplus-recruits (roughly one thousand 4 years old by year) to be produced by the juvenile (stage IV and V) lobster hatchery operating in the analyzed fishery area. This minimum level, if the hatchery impact has to be assessed from surplus commercial...

Autores: Berne, Serge; D'Ozouville, Laurent.
Ce rapport présente les résultats du suivi cartographique et géo­morphologique de la pollution des côtes bretonnes par le pétrole de l'AMOCO CADIZ jusqu'au mois de Mars 1979, c'est-à-dire un an après la catastrophe.  Les reconnaissances aériennes associées à des visites détaillées des 160 stations établies entre la pointe ST MATHIEU et le sillon du TALBERT ont permis de suivre l'arrivée du pétrole à la côte puis sa disparition plus ou moins rapide. Pour dresser ce bilan, plus d'une vingtaine de vols ont été effectués ainsi que 5 campagnes de terrain ; débutés immédiatement après le naufrage de l'AMOCO CADIZ en collaboration avec de nombreux organismes, ces travaux se sont poursuivis à partir de Novembre 1978 dans le cadre du program­me de suivi écologique...

Essai de caractérisation de quelques régimes sédimentaires ayant prévalu sur la marge nord du golfe de gascogne depuis le début du cénozoïque
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Auffret, Gérard-andré.
Paleocene to Holocene sediments have been sampled from the northern margin of the Bay of Biscay (Meriadzek Terrace). Micropaleontological indicators suggest that this area has remained at upper abyssal depth (2000-2600 m) throughout this time ; moreover it seems to have been ouside the influence of massive terrigenous input through high density turbidity current. The comparaison of paleogene and quaternary sedimentary regimes points to a drastic difference between the sedimentation rate from these two episodes. This difference is related to the onset of global glaciation as soon as Middle Miocene with a subsequent increase of the sea level regressive trend which has been occuring since the uppermost Cretaceous. It appears to us that the sedimentary model...

Evolution saisonnière des populations de diatomées benthiques dans les lagunes aménagées de Certes
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Malissen, M.o.; Lasserre, P.
In lagoons and estuarine ecosystems, the benthic microflora contributes considerably to the primary production of the area and consists largely of diatoms Monthly samplings have been made from December 1976 to March 1978 in a shallow station characterized by the lack of macrophytes. Two sets of monthly sam­plings were made allowing in theone hand a qualitative analysis and on the other hand a quantitative study by cellular counts. The diatom populations show a cyclic evolution with two peaks : one in February 1977 and the other in September 1977. This cycle is confirmed by the di­versity and dominance analysis. Seasonal evolution is characterized by the domi­nance of one or more species with well marked succession of dominant species (Nitzschia Navicula et...

Autores: Divanach, P.; Sube, J.
Previously to its use as culturing medium for algae, we have studied the various characteristics of the sewage extracted from marine fish rearing ponds, through a purificating system called "foamer". Qualitatively, this sewage differs from the sea water which produced it on various points : It is richer than the water in Organic Carbon, Organic Nitrogen, Ammonia, particulate matters, phosphorus and varied metals. However the concentration factors are not constant and they change in time. This sewage is toxic for some group of animals and this toxicity varies with the concentration but also the age of the product. Finally, it is eutrophicant and this richness enables to the growth of algae for long periods but the boundary between toxicity and eutrophy Is...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Latrouite, Daniel; Perodou, Dominique.
Au cours des 15 dernières années, l'évolution des techniques ostréicoles a profondément modifié la structure sociale de cette profession. La maladie de l'huître portugaise (1970/1971), celle de la plate depuis 1969, ont provoqué de nouveaux bouleversements. Ces derniers évènements montrent les risques que courent les exploitations reposant sur la monoculture. La mise au point au JAPON, aux USA puis en ANGLETERRE et en FRANCE des techniques de production du naissain de diverses espèces de palourdes et le développement des écloseries à mollusques, permettent d'envisager l'élevage de ces coquillages pour lesquels la collecte en milieu naturel n'est pas contrôlée.

Modification de l'équilibre démographique de la meiofaune dans les lagunes aménagées de Certes
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Castel, J.; Lasserre, P.
Monthly sampling for a 2-year period allowed comparisons between the communities of meiofauna living in fish ponds ("reservoirs a poissons de Certes") and those inhabiting a contiguous tidal pool ("lac de tonne"). Nematods and copepods constitute the bulk of the meiofaunal populations. The community structure of co­pepods is considered in detail.The communities of copepods are clearly separated between the two areas. In terms of abundance, diversity and species persistence, the meiofauna is more stable in the intertidal pool than in the fish ponds. When the seasons are well marked, the community structure of the cope­pods in the fish ponds is nearly equilibrated in spring, with a maximum of diver­sity in May-June. During high eutrophication periods, in...

Gypsum-calcite rosettes in sediments from the Congo deep-sea fan
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Pautot, Guy; Fontes, Jc.
The occurrence of "rose"-like aggregates with diameters of a few centimetres in a core of dark brown siliceous mud of the Congo deep-sea fan (depth of 4 070 m) is reported. The rosettes are well preserved. They have the crystalline outlines of gypsum but are made of calcite (97% with traces of quartz and clay minerals. In addition to the preserved specimens, fragments of rosettes occur at various levels in the sedimentary column. The core was taken on a levee of the submarine canyon and the depositional environment is thus compatible with down-slope sedimentation. Discussion concerning the origin of the rosettes takes into account regional morphology and structure, sedimentary cover and the isotopic composition of calcite from the rosettes. The most...

Autores: Dufour, P.; Cremoux, Jl.; Slepoukha, M.
"In vitro" enrichment experiments on natural populations have been used to determine the nutrients controlling the potential biomass of phytoplancton in the Ebrié coastal lagoon. The limiting nutrients were generally nitrogen, phosphorus and carbon, in this order ; in three cases out of eleven, P and N act simultaneously ; in an extreme eutrophication case, N, P and C were all limiting. No effect was observed following addition of metals, vitamins or chelators. The limitations deduced from the enrichment experiments show a. good agreement with the elementary composition of the external medium ; in waters potentially limited by N alone, the dissolved inorganic nutrients have a N : P ratio lower than 25. The agreement is poorer when the sestonic N : P ratio...

Les premiers stades connus du parasite ont été mis en évidence en Bretagne pendant les mois de juillet et d'août (GRIZEL et TIGE, 1977). Suite à ces observations, un essai a été réalisé en 1978 pour savoir si l'infestation avait bien lieu à ces dates ou si elle se faisait antérieurement sous une forme non décelée actuellement et subissant des transformations profondes dans les tissus de l'huître. Les résultats montrent que l'infestations se fait effectivement pendant l'été, à partir du mois de juillet jusqu'à la fin du mois d'août. Elle fut dans l'ensemble faible; les lots les plus infestés sont ceux qui ont séjourné le plus longtemps en zone contaminée.

Atlantic salmon sea ranching in Ireland
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Piggins, D.j.
The four main Irish smolt farms have contributed to the development of adult salmon fishing in fixed estuarine fisheries. But the "re-catches" currently take place at an insufficient rate compared with the economic norms of a "sea-ranching" operation. One of the main limiting factors for the repopulation from farm salmon is the lower viability of farm smolts compared to wild individuals. This might be caused by a combination of physiological or behavioural deficiencies linked to the farming techniques, but also by the presence of some latent pathogenic germs on the freed smolts.

Ecology of the benthic communities of the deep North East Atlantic
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Laubier, L.; Sibuet, Myriam.
Deep benthic communities of the Bay of Biscay (North East Atlantic) have been thoroughly sampled during seven cruises between 1972 and 1974.Some 200 samples using three main types of gear (corer, epibenthic sled and beam trawls) have been performed. Sediment characteristics (granulometry, organic content) and faunal densities for each size assemblage are given.Continental influences appear to increase macrofaunal density.Compared with other areas, the central part of the Bay of Biscay appears to have a low faunal density. This fact can be related to the existence of a mesoscale gyre of the upper layer, which could be responsible for a low primary productivity. [NOT CONTROLLED OCR]

Autores: Couteaux, B; Jegou, Anne-marie; Merceron, Michel; Piriou, Jean-yves.
This report is the first stage of the Inventory of Potential Sites for Aquafarming along the Côtes-du-Nord shoreline. This type of inventory was conducted previously in Seine-Maritime, in Basse-Normandie, in Finistère, and along the central part of the Atlantic coast. This kind of study is generally motivated by two findings: -the growing use of the shoreline area for various activities -the need to set aside suitable sites for the development of aquafarming.  In order to make consistent development choices, it is important to know as well as possible the aquafarming potential sites that we have available, their size, their nature, their geographic distribution, as well as the state of the techniques to be implemented.  In Brittany itself, a quick...

Preliminary results of a seismic refraction study in the meriadzek-trevelyan area, bay of biscay
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Avedik, Félix; Howard, David.
Seismic refraction studies over the Meriadzek-Trevelyan area in the north of the Bay of Biscay have established four main geological sequences : Cenozoic (1.9 to 2.8 km/s) ; Cretaceous (3.2 to 4.0 km/s); lower to middle Mesozoic (4.5 to 5.0 km/s) ; pre-Mesozoic (5.4 to 6.3 km/s). These agree broadly with the adjoining Western Approaches and English Channel areas to the northeast. The sub-sedimentary structure between the Meriadzek Terrace and the Trevelyan escarpment is of continental origin having a block-faulted pattern and is interpreted as a southwestward prolongation of the continental structure. The blockfaulted form is considered to have originated during the rifting of the Armorican Continental margin and may have been influenced by a tectonic...

Massive ore-grade zinc, copper and iron sulphide deposits have been found at the axis of the East Pacific Rise.Although their presence on the deep ocean-floor had been predicted there was no supporting observational evidence. The East Pacific Rise deposits represent a modern analogue of Cyprus-type sulphide ores associated with ophiolitic rocks on land.They contain at least 29% zinc metal and 6% metallic copper.Their discovery will provide a new focus for deep-sea exploration, leading to new assessments of the concentration of metals in the upper layers of the oceanic crust.

Elevage de copepodes harpacticoïdes (Tisbe holothuriae) en cycle complet. Rôle des facteurs température et nutrition
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gaudy, R.; Guerin, J.p.
Following are results obtained in our laboratory during breeding expe­riments with an harpacticoid copepod, Tisbe holothuriae. In small size volumes (200 ml), the potential production appears to be higher when an artificial compound food of animal substances is used instead of a vegetal diet. In medium volume experiments (100 l) the production is related to the surface available for animals in breeding tanks, Breeding in complete cycles can be obtained using various foods, but the quality of diet may markedly affect the characteristics of the vital cycle, such as the length of the fertility period and fecundity. Temperature has a cru­cial effect, chiefly on dynamic preoccesses, that is to say, developmental rate and average generation time. With different...

Discharges of urban sewage water and waste heat from industries or power plants can be used in modern saltwater aquaculture. Urban sewage water diluted to 30 % in seawater which temperature is increased of 10 to 15° C gives a primary productivity equal to the produc­tivity of a standard culture medium. That bio-treatment which includes the addition of calories to the seawater, eliminates up to 90 % of the phosphorus and the nitrates.

Autores: Nicolle, Jean-pierre.
Les prélèvements de saumon fumé dans les ateliers de fumage montrent que la conservation n'est pas toujours ce qu'elle devrait être. Cette denrée vendue tout d'abord exclusivement dans les magasins spécialisés fait maintenant l'objet d'un commerce actif dans les supermarchés. Pour parer à une prolongation éventuelle du délai entre le fumage et la consommation, certains fumeurs ont tenté d'ajouter du nitrite de sodium au sel ce qui devait, selon eux, limiter la croissance bactérienne, maintenir la coloration de la chair et même faciliter le tranchage ultérieur.

Japanese scallop Patinopecten yessoensis J. is one of the few examples of successful restocking of a marine population. Juveniles collected (on natural grounds) in almost unlimited number are used either for hanging or bottom culture. In the first case animals are kept in pearlnets until commercial size, in the second one, juveniles are released in the sea when vulnerable stages of early life are over. Remaining natural stocks are very scarce and limited.

Structure et évolution de la macrofaune invertébrée d'un écosystème lagunaire aménagé (réservoirs à poissons de Certes)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Labourg, P.j.
The invertebrate macrofauna of the brackish ponds of Certes on the eastern coast of the Bassin d'Arcachon is distinguished by a small number of species (2 to 20) and strong dominances in abundance and biomass, with low diversity (Shannon's index) and eveness. In the "plats" which have a depth of 0,20 to 0,60 metre, the species diversity is very low, populations are widely fluctuating with eurytopic, and many explosive opportunistic species. In the "profonds" (1 to 2 metre) diversity is greater, because environmental parameters are most predictable; catastrophic mortalities due to physiological stress are characteristic of temporal population fluctuations. Theses man-made ecosystems are now becoming natural ecosystems and fish farming has declined since...

The breeding cycle of scallops (Pecten maximus L.) from a population harvested in Bay of Saint-Brieuc has been surveyed over a period of three years with a classical gonad index, which is useful for the detection of the maturity and first spawning at the beginning of the season. Then phenomena are more complex with rematuration and late spawning.So we tried to find a new biochemical index and in 1977 the in situ sexual maturation of individuals from this population was studied simultaneously by measuring concentration of aspartate transcarbamylase (ATC), which was used as a potential index of gonad growth.A positive correlation was evident between this activity and the growth rate of the gonad.During the spawning period, the variations of ATC activity are...

Des variations de température, salinité et vitesse de courant de fréquence voisine de celle de la marée ont été observées presque partout dans l'océan. On constate qu'elles sont généralement beaucoup plus prononcées sur le plateau continental près de la côte qu'au large. On soupçonne depuis de nombreuses années que ces phénomènes sont dus aux mouvements verticaux des particules fluides ou des ondes internes ayant la fréquence de la marée (marées internes). Depuis le début du siècle, de nombreux articles théoriques ou expérimentaux concernant les phénomènes des ondes internes dans l'océan ont été publiés. La majeure partie d'entre eux est basée sur la théorie fondamentale des ondes internes ayant elle-même pour origine les premiers travaux de FJELSTAD...

Situation et perspectives de la pisciculture marine extensive en Europe et dans le Bassin Méditérranéen
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Girin, M.
Extensive lagoon farming, a traditional activity in various European and Mediterranean countries, represents a production of some 10,000 tons/year. It depends on a variety of social, technical and biological factors, which do not easily meet nowaday. It basically implies a management of the lagoon restricted to the benefit of a few people, an investment and a,financial return per hectare rather low, in an exploitation entirely based upon a supply of wild fry from the open sea.  The author analyses under what conditions the present improvements in the control of fry production for some species could bring new prospects for the development of that activity and possibly open the way to restocking programs in the open sea.

Since the beginning of the epizooty of the flat oyster Ostrea edulis on the Atlantic coast (Comps, 1970), it has been observed that the parasitosis did not develop in the Mediterranean Sea in oysters from the Thau lagoon even though a large part of the culture is made up of young oysters from Brittany. However, some episodic studies only rarely found the presence of Marteilia refringens in the oysters from the lagoon.

The Galapagos mounds sea-floor hydrothermal system is at least 300,000 years old and once produced manganese-poor sediments, which nearly blanketed the area of the present mounds field. Present-day mound deposits are limited manganese-rich exposures, suggesting that the system has changed from rock- to water-dominated and has diminished in intensity with time. [NOT CONTROLLED OCR]

Recent mariculture techniques in Japan
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Uno, Yutaka.
The production of sea products in Japan increases regularly, reaching 10 million tonnes in 1972. In 1976, marine aquaculture products accounted for about 9.8 % of the total amount in quantity and about 19 % in value. The aquacultural production consisted mainly of Japanese amberjacks, Japanese shrimps, oysters and pearl oysters, amanoris, etc... Recently, the shrimp, red sea-bream, king scallop and abalone mass production techniques have improved significantly, driving national or prefectorial bodies to create new structures enabling a mass production of these species in order to restore or increase shallow water resources. After numerous feasibility studies, these farms now produce more than 200 million larvae (fishes, molluscs, crustaceans) designed to...

Evolution des caractéristiques chimiques et biologiques des sédiments en circuit clos. III. Bilan azoté de systèmes polytrophes
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Chamroux, S.; Boucher, G.
The evolution of nitrogen content in experimental closed circuit ¿and filters was followed, each tank being fed with different quantities of soluble organic matter. According to the trophic conditions, two types of metabolism could be observed : - a loss of nitrogen (denitrification), reaching almost 90% of the nitrogen in­put in eutrophic conditions, and close to 35% in mesotrophic conditions. - a gain in nitrogen (fixation), a predominant metabolism in oligotrophic and eutrophic conditions. Nitrogen retention in the sediment increases slightly with the organic matter input, but no proportionality could be established. It seems that the sediment, by its bacterial metabolisms, regulates its own organic matter rich­ness.

Un secteur côtier d'intérêt scientifique particulier, les bas-champs de Cayeux (Somme)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Regrain, R.; Vignon, F.; Wattez, J.r.
The Cayeux Bas-Champs, Picardy, are a coastal marsh area, sheltered from the sea by an evoluting pebble ridge (retreat at the older part, progradation at the distal end). A remarkable vegetal cover has found here an environment favouring its development and conservation. These Bas-Champs also constitute a station used in bird migrations. As several plans for recreation and touring have been put forward, it seems necessary to protect some biotopes of scientific interest. Proposals are made in this respect.

Alimentation et croissance de bivalves filtreurs en bassin aménagé
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Riva, A.; Lelong, P.
The lagoon of Brusc located on the Mediterranean coast (Var­France) is subjected to climatic and hydrologic particular condi­tions. The low values observed for nutrient into the sea water affect the evolution of phytoplankton. Thus chlorophyll concen­tration measured in the lagoon give an annual average of 0.42 mg. m-3 . The growth of two bivalves species : Cerastoderma glaucum and Venerupis semidecussata was compared between two stations where one population of each species are implanted. The culture of this molluscs is made in the lagoon and in outdoor pound dug on the old salt-pan near at hand. In the pound, subjected to natural climatic conditions, a great growth is noted for this two species. The growth rate appear better than the populations of the...

Recent progradation of the magilligan foreland co. Londonderry, northern ireland
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Carter, R.w.g.
Since c. 1950 the shoreline at Magilligan Point has prograded by almost 200 m. Sequences of beach ridge and dune development are directly related to erosion of the adjoining coastline and the efficiency of the sediment transport system. Sand moving along the shore becomes captured by two overlapping and counteractive drift cells near the Point. Given the present conditions of sediment scarcity it is thought that this recent progradation is only a short-lived stage in the progressive destruction of the foreland.

La phytocoenologie comme outil de définition des secteurs côtiers à préserver
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gehu, J.m.
The phytocoenological method, which consists in defining the elementary units of vegetation, appears to be the best one for the choice of the parts of the sea-shore to be protected. Based on a list of associations in a given site, it provides an expression of the diversity of the flora in the littoral environment, which is a better criterion than the presence of endemic or rare species. Examples are given for cliffs and dunes on the Atlantic coasts of France (Tables 1 and 2). This method, however, can be used by good specialists only.

Macrobrachium rosenbergii culture in Polynesia : pH control in experimental pond waters by phytoplankton limitation with an algicide
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: AQUACOP.
Macrobrachium rosenbergii ponds at the Centre Océanologique du Pacifique are subject to increases in pH exceeding 10.5 during growing experiments. The high levels of pH are responsible for mortality of prawns, especially when molting. The photosynthetic activity of dense phytoplankton blooms are primarily responsible for high pH. The algicide Clarosan (CIBA-Geigy) was used to thin phytoplankton blooms. Experiments showed that treatments with 0.02 mg/liter result in a rapid fall in the pH. At this dose Clarosan is not deleterious to the prawns. [NOT CONTROLLED OCR]

Conséquences sur la maturation et la croissance d'une transplantation de naissain de pecten maximus (L.)

Autores: Antoine, L.; Garen, P.; Lubet, P.
Some king scallop reimplantation experiments on an old deposit (Roadstead of Brest) have been conducted with spats collected in the Bay of Saint-Brieuc. In the introduced population, the length growth has not proved very different from that of the original population. But scallops have acquired the characteristics of the indigenous population as far as valve curvature is concerned. They also showed a precocious sexual maturity which did not exist at the same time in the original population. The acquisition of indigenous characteristics could have interesting consequences for the commercialisation of such a repopulated deposit.

Structure et importance des peuplements zooplanctoniques dans la baie d'Arcachon : milieux ouverts et lagunes aménagées de Certes
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Castel, J.; Courties, C.
Specific composition and distribution of the zooplankton in Arcachon Bay varie along a salinity gradient from oceanic to neritic and lagoonal condi­tions. A peak of density and biomass is recorded in spring due to an increase of holoplanktonic species as well as larvae of benthic Invertebrates. A second maxi­mum of abundance is observed in autumn. The community structure of copepods and polychaets larvae is considered in detail. The diversity (Shannon index, Sanders's rarefaction) decreases from the mouth of the Bay to the inner neritic water mass. Demographic parameters indi­cate that the populations structure is affected by the salinity gradient. Biomass increases significantly from the oceanic water to the inner neritic water mass while the species...

Determing Higher Fatty Acid Levels in Plant Materials
Provedor de dados: NWISRL Publications
Autores: Mayland, H.F.
The higher fatty acids (HFA) are important plant constituents that are implicated in the grass tetany hazard in livestock.  A method is given whereby a technician can analyze 12 forage samples daily for HFA content.    The method consists of saponifying the plant material in ethanol and KOH and extracting the subsequently acidified HFA with petroleum ether.  The petroleum ether phase is evaporated and the HFA residue is dissolved in ethanol and then titrated with standardized isobutanolic KOH in the absence of Oxygen by using an Nitrogen atmosphere.  A standard plant sample, analyzed over a 37-day period, had a mean of 136 mmol H+kg ± 4.5, where 0.1 mmol H+ℓ palmitic standard  was determined with an accuracy of 99 ± 1.9%.

Factors Affecting Curly Top Damage to Sugarbeets and Beans in Southern Idaho, 1919-1977
Provedor de dados: NWISRL Publications
Autores: Blickenstaff, C.C.; Traveller, Del.
Curly top, a virus disease transmitted only by the beet  leafhopper, was a serious threat to the sugarbeet industry  in south-central Idaho from 1919 through 1941 and to dry  edible and snap bean production from 1924 through 1957. The  frequency and severity of damage are charted from 1919  through 1977. The development of plant varieties resistant  to curly top is attributed as the major factor in lessening  damage to sugarbeets since 1942; the development of plant  resistance in beans proceeded at a slower rate, but has also  become a major factor in lessening damage. Other possible  factors discussed are: (1) size of overwintering beet leafhopper  populations, (2) early spring migration of beet leafhoppers,  (3) insecticidal control in desert areas, (4)...

The deep-water Scleractinia of the Caribbean Sea and adjacent waters
Provedor de dados: Naturalis Digital Academic Repository
Autores: Cairns, Stephen D.
Ahermatypic Seleractinia are very common throughout the tropical western Atlantic, both in number of species and individuals. Of the Scleractinia known from the western Atlantic, there are over twice as many species of ahermatypes (species that do not have symbiotic zooxanthellae) as hermatypes (the shallow-water “reef corals,” all of which have zooxanthellae). This paper is a review of all known species of deep-water Scleractinia that occur in the Caribbean Sea and adjacent waters, all of which are ahermatypic. The term “deep-water” is used here to designate depths equal to or greater than 200 meters; the 88 species treated all have bathymetric ranges that exceed 200 meters at their deepest points. Another 27 ahermatypic species are confined to the...

Autores: Smit, P.
At the beginning of the nineteenth century the Netherlands lagged behind intellectually when compared with the surrounding countries. This was especially true in the field of natural history. If we wish to understand the reasons for this backwardness we must remember that during the second half of the eighteenth century the neighbouring countries had started to build and maintain an active trade, whilst the Dutch merchants had secured their capital by investing in those countries, especially in England. The fast decline of our trade with the colonies was one of the consequences of this development.

Provedor de dados: Naturalis Digital Academic Repository
Autores: Pafort-van Iersel, Trudy; Spoel, S. van der.
The phylogenetic relation between Clio pyramidata Linnaeus, 1767, and Cymbulia peroni De Blainville, 1818, has been studied with regard to the structure of their muscle systems. Specimens of both species collected from the North Atlantic Ocean and the Mediterranean were sectioned 5 µm thick and stained with Haematoxilin-Eosin, Crossmon or Azan for histological purposes or they were studied as cleared dissected or entire animals. The columellar muscle and subectodermal wing muscles of both species are described. It is concluded that Clio shows neoteny since it develops without metamorphosis. The asymmetry in anatomy proves that both Clio and Cymbulia descend from spiralised ancestors. For Clio two primitive characters are discussed which may be due to the...

Autores: Holthuis, L.B.
Introduction. — By far the most important and fundamental carcinological publication of the first half of the 19th century unquestionably is Henri Milne Edwards's (1834-1840) "Histoire naturelle des Crustacés", which treated all species of Crustacea known at that time in an exceedingly clear and comprehensive manner. The work was published in three volumes of text and one atlas. The dates of publication of it have never caused any difficulty. It was generally accepted that volume I was published in 1834, volume II in 1837, and volume III in 1840. These dates have never been challenged, and on closer examination indeed prove to be correct. About the date or dates of the atlas authors were vague and usually cited 1834-1840, or 1840, or they cited the atlas...

Pontonides sympathes, a new species of commensal shrimp (Crustacea, Decapoda, Pontoniinae) from Antipatharia in the Galapagos Islands
Provedor de dados: Naturalis Digital Academic Repository
Autores: Ridder, Ch. de; Holthuis, L.B.
During a stay at the Galapagos Islands (1975-1976), one of us (Ch. de Ridder) made a study of Gorgonaria and Antipatharia, paying special attention to commensals found with these corals. On Antipathes galapagensis Deichmann, 1941, a species of the pontoniine shrimp genus Pontonides was observed, which proved to be new to science. The present paper describes the new species and its living conditions. Pontonides sympathes new species (figs. 1-3) Material examined. — Punta Pitt, north-east coast of San Cristobal Island, Galapagos Archipelago, Ecuador; on Antipathes galapagensis Deichmann growing on a lava bottom at a depth of 8 m; surface water temperature 23.9oC; 2 February 1976; Ch.

Taxonomie en nomenclatuur van de koebraam
Provedor de dados: Naturalis Digital Academic Repository
Autores: Beek, A. van de.
The author discusses several aspects of Rubus inermis Pourr. (= R. ulmifolius Schott). The discovery of an earlier name made it necessary to change the name of this well known and widespread species. R. inermis is easely recognised by: turio thick bluish pruinose, glabrous or with stellate hairs; leaflets small, coriaceous, white tomentose beneath, usually without longer hairs; inflorescence cylindrical, leafless; petals broad, usually pink; stamens only a little longer than the styles. Diploid (2n=14). It prefers sunny hills, roadsides and hedgerows on a substratum rich in lime and has a Mediterranean-atlantic distribution. Fig. 1 gives several forms of the top leaflet, fig. 2 shows the distribution in the Netherlands.

Structure and Dynamics of the French upper Rhône ecosystems XII. An inventory of helminth fish parasites from the upper Rhône river (France)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Maren, Marion J. van.
Eleven species of helminth parasites (five acanthocephalans, five cestodes and one trematode) are reported from altogether sixteen fish hosts in the Rhône River, N.E. of Lyon. The most common parasite is Pomphorhynchus laevis, which occurs in all fish species examined. Echinorhynchus borealis seems to he restricted mainly to Burbot. Metechinorhynchus truttae was not frequently met with, but was very numerous in Grayling from the river Furans. Acanthocephalus anguillae was found in fishes from the so-called ”lônes” (backwaters). A. lucii was rarely encountered during the present study. Of Cestoda, Caryophyllaeus laticeps is confined to fishes feeding on muddy substrates, Bathybothrium rectangulum was found in Barbel, and Eubothrium rugosum in Burbot....

Is er een grens tussen het Löss- en het Krijtdistrict?
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hommel, P.
The subdivision of the Netherlands in plantgeographical districts by VAN SOEST (1929) has recently become the subject of a series of investigations by the department for the Netherlands flora of the Rijksherbarium in Leiden (MENNEMA, 1978). This paper deals with one of these investigations, a field study on the border of the Loess and the Chalk district in the South of the Netherlands. In the course of 1976 30 square kilometers were visited and an inventarisation was made of their floristic composition. The data for the distinct square kilometers were subsequently processed by means of the so-called Mennema-methody (MENNEMA, 1973), comparing them in number of species as well as on the basis of „ecologicalgroups” and some critical species.

A record from Surinam of the bat Chiroderma trinitatum Goodwin, 1958 (Mammalia, Chiroptera)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bergmans, W.
Re-examination of a collection of bats from Surinam in the Zoölogisch Museum, Amsterdam, uncovered a specimen representing the Phyllostomatid bat Chiroderma trinitatum Goodwin, 1958. This species does not appear in the monograph of the Chiroptera of Surinam by Husson (1962), nor in his more recent works on the mammals of that country (1973; 1978). The present specimen therefore seems to be the first record from Surinam. It is a young adult female, captured after it had flown into a house at night on 1-II-1967, by H. Nijssen at Ligorio, a village on the river Gran Rio about 16 km southwest of Djoemoe in the Brokopondo District. It has been preserved in alcohol, with extracted skull, and is registered as ZMA 10.136.  IDENTIFICATION In a recent paper dealing...

The species of Agathis (Araucariaceae) of Borneo
Provedor de dados: Naturalis Digital Academic Repository
Autores: Laubenfels, David J. de.
The important genus Agathis is well represented in the rich flora of the island of Borneo. In some places it forms nearly pure stands and has been heavily exploited for its resin and for lumber. Three species, one of which merely represents leaf variations from another, have been proposed previously for this genus in Borneo (Warburg, 1900; Meijer Drees, 1940). Several hundred collection numbers can be found in the major herbaria, much the majority of which belong to one species. This is particularly true for the non-Asian herbaria. During several field trips to Borneo, however, I identified three additional quite distinct unnamed species. The great variability of leaf size and shape even on individual plants in this genus together with difficulty in making...

A dedication to ODOARDO BECCARI, the greatest botanist ever to study in Malesia, is long overdue. Although best known as a plant taxonomist, his versatile genius extended far beyond the basic field of this branch of Botany, his wide interest leading him to investigate the laws of evolution, the interrelations between plants and animals, the connection between vegetation and environment, plant distribution, the cultivated and useful plants of Malesia and many other problems of plant life. But, even if he devoted his studies to plants, in the depth of his mind he was primarily a naturalist, and in his long, lonely and dangerous explorations in Malesia he was attracted to all aspects of nature and human life, assembling, besides plants, an incredibly large...

Some remarks on the identity of the Japanese rays Raja Kenojei Müller &amp; Henle, 1841, and Raja Meerdervoortii Bleeker, 1860
Provedor de dados: Naturalis Digital Academic Repository
Autores: Boeseman, M.
Rejecting without valid argumentation a lectotype selection for Raja kenojei Müller &amp; Henle, 1841, by the present author (1947), Ishiyama (1967) indicated another of the four Leiden types as such. Both selected specimens are shown to represent only the different sexes of the same species, which is not conspecific with R. kenojei sensu Ishiyama et al. (= ? R. japonica Nyström, 1887) but rather with R. porosa Günther, 1847, as understood by Ishiyama. One of the R. kenojei types is referred to R. meerdervoortii Bleeker, 1860, a distinct species not identical with R. kenojei in either interpretation, and of which R. macrophthalma Ishiyama, 1950, may well prove to be a junior synonym.

Provedor de dados: Naturalis Digital Academic Repository
Autores: Pierrot-Bults, A.C.
The inadequacies of the original descriptions of Sagitta decipiens Fowler, 1905, and S. sibogae Fowler, 1906, have led to confusion concerning these species. Sagitta neodecipiens Tokioka, 1959, is a junior synonym of S. decipiens Fowler, 1905. S. sibogae Fowler, 1906, is the valid name for the species usually incorrectly named S. decipiens (non Fowler, 1905) because of the redescription of Ritter-Zahony (1911). S. philippini Michael, 1919, is a junior synonym of S. sibogae. The two valid species are redescribed from the types, and lectotypes have been designated.

The karyotypes of two Dugesia species from Corfu, Greece (Platyhelminthes, Turbellaria)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Ball, Ian R.
Dugesia gonocephala (Dugès, 1830) and D. polychroa (Schmidt, 1861), collected from the Greek island of Corfu, have been investigated karyologically. The former is a sexual diploid (2n = 16) in which all the chromosomes are metacentric. The latter is a sexual diploid (2n = 8) with one submetacentric and three metacentric chromosome pairs. Within the Dugesia lugubris-polychroa complex seven biotypes are known. The karyotype of D. polychroa from Corfu is most similar to biotype G from the western Mediterranean. However, there are subtle karyological and morphological differences between the two forms and thus the Corfu population is not assigned to biotype G but is considered to have been derived independently from the basic biotype A. Thus it represents an...

Provedor de dados: Naturalis Digital Academic Repository
Autores: Nagelkerken, W.P.
Epinephelus (Cephalopholis) cruentatus (Lacépède, 1802) [Petrometopon cruentatum], the Graysby, is one of the most common groupers on the coral reef at the southwest coast of Curaçao. They are very abundant at a depth from 7½ to 9 m. A second, lower maximum in their vertical distribution is found at a depth of 30 m. Juveniles are found mainly at a depth of about 6 m in crevices of the coral species Montastrea annularis. The calculated number of fish actually present appeared to be 24 specimens in a transect of 240 m2 at a depth of 9 m. Measurements were made of the percentage of bottom cover and of the quantity of coral structure. A strong correlation was found between both. For the studied coral reef in Curaçao a high percentage of bottom cover means at...

Transplantation experiments with Mediterranean gorgonians
Provedor de dados: Naturalis Digital Academic Repository
Autores: Weinberg, Steven.
Branches of gorgonians belonging to four different Mediterranean species (Eunicella singularis (Esper), Paramuricea clavata (Risso), Corallium rubrum (Linnaeus) and Lophogorgia ceratophyta (Linnaeus)) were transplanted to different habitats by means of three different methods, and survival and growth rates were observed over periods ranging from three months to over two years. It was concluded that transplantation of animals still fixed on their natural substratum is to be preferred over transplantations involving artificial devices. Transplanted adult branches of all four species tolerate conditions under which the species are not usually encountered. Tolerances or preferences of larval and juvenile phases must account for these discrepancies. Transplants...

Rare and remarkable Foraminifera of the Caribbean Sea
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hofker, J.
When studying samples from the Virgin Islands area, some new Foraminifera were found, together with other species of which little was known about their internal structure and taxonomic status. Most specimens came from samples W of St. Croix, collected by Th. Mortensen at about 17.5°N 64°W, depths about 200 and 300 m. These samples are very rich in benthonic Foraminifera, but relatively poor in planktonic species all of which are relatively small and with very thin tests. This material contained many specimens already described in previous publications (e.g. Hofker 1956, 1972 and 1976). The material studied has been deposited in the collections of the Netherlands Geological Survey at Haarlem, Netherlands.

Developmental anatomy of Coprinus
Provedor de dados: Naturalis Digital Academic Repository
Autores: Reijnders, A.F.M.
The aim of this study has been to compare the ontogenetic structures of as many species of Coprinus as possible in order to obtain a better insight into their mutual relationships. The sequence of development of the parts in the first phases of primordium development has been traced with greater precision here; several degrees of rupthymenial hymenophore development have been distinguished; the veil and pileipellis structures and the corresponding terminology have been critically discussed. Finally, an attempt has been made to establish phylogenetic relationships between about 27 species, but to acheive a higher degree of accuracy in this field, ontogenetic information concerning still more species is required.

L’évolution du genre Jaera Leach (Isopodes; Asellotes) et ses rapports avec l’histoire de la Méditerranée
Provedor de dados: Naturalis Digital Academic Repository
Autores: Veuille, Michel.
The genus Jaera includes 19 species or subspecies, mostly endemic to Europe. The new forms J. nordmanni nordmanni, J. n. occidentalis, Jaera istri, and J. n. illyrica are described. The phylogeny of this group can be inferred. The cladogenetic events leading to its differentiation appear closely correlated to the origin of the Mediterranean basin and to the glacial periods.

Mycena flocculentipes is reduced to the synonymy of M. hiemalis. Mycena metata is maintained as the correct name for M. vitrea var. tenella sensu Ricken, and M. phyllogena becomes a synonym. Mycena corticola is rejected as an ambiguous name, while M. meliigena seems a plausible choice as the correct name for M. corticola sensu Kühner.

Provedor de dados: Naturalis Digital Academic Repository
Autores: Sluys, R.
Physocypria kliei Schäfer, 1934, was found in water-bodies near Maarssen and Simonshaven (The Netherlands). It can be characterized as an oligohaline species occurring all the year round. The species is new to the Dutch fauna. It is concluded that Physocypria perlata Rome, 1943, is a junior synonym of P. kliei Schäfer, 1934. Potamocypris unicaudata Schäfer, was collected in a water-body near Rockanje (The Netherlands). Evidence is provided that Potamocypris vanoyei De Vos, 1946, is a junior synonym of P. unicaudata Schäfer, 1943.

A collection of frogs was made in Madagascar between November 1970 and May 1973. Observations in the field and investigations in the laboratory yielded a variety of new taxonomic characters, such as the morphology of eggs and larvae, the reproductive behaviour, the habitat and habits of both the terrestrial and aquatic stages, the mating call and the colouration in life. Karyotype studies and researches on the nuclear DNA amount of these frogs were published previously. Because of various contradictions between the results of this study and the current classification, both these new and the more convential morphological characters were used for a re-evaluation of the systematics of the Mantellinae Laurent, 1946. As a result, this subfamily can be...

In less than 55 years after its introduction in 1924 S. anglica succeeded in almost completely crowding out the original S. maritima (Curt.) Fern. According to C. E. Hubbard, who kindly revised several of our specimens, only 4 collections belong to the hybrid S. x townsendii, 2 to a triple-hybrid?

The light-dependent behaviour of planula larvae of Eunicella singularis and Corallium rubrum and its implication for octocorallian ecology
Provedor de dados: Naturalis Digital Academic Repository
Autores: Weinberg, Steven.
The behaviour of Mediterranean octocoral planulae was studied in light-dark situations and in a light gradient. Larvae of Eunicella singularis (Esper, 1794) reacted photopositively but it is uncertain which mechanism (klinotaxis or klinokinesis) determines this property. The blind larvae probably possess a dermal light sense, but it cannot be excluded that the yolk contains photosensitive carotenoids while the symbiotic zooxanthellae may also play a role. The photopositive behaviour of planulae of this species explains some aspects of the distributional ecology of adult colonies. It was also found that for the induction of settlement and metamorphosis the chemical properties of a given substratum seem to be far more important than its roughness. Larvae of...

In the first decades of its existence the interest of the Rijksherbarium was certainly not directed towards the study of the Dutch and European flora. The initiative to embark on research of the flora of the Netherlands was born outside the walls of the institute. In 1845, R. B. van den Bosch initiated — elsewhere in Leiden! — the foundation of the ‘Vereeniging voor de Nederlandsche Flora’ (Society for the Netherlands Flora), later the ‘Nederlandsche Botanische Vereeniging’ (N.B.V.), to promote the knowledge of the flora and encourage the collection of plants for a ‘Vereenigingsherbarium’.

Autores: Maren, Marion J. van.
Monthly samples of Gammarus fossarum have been taken in the Rhône river system near Lyon, to determine the size composition and reproductive activity throughout the year. The acanthocephalan parasites of this gammarid species were also regularly collected. Furthermore, the intestinal tracts of a number of fishes (amongst others Thymallus thymallus), feeding mainly on Gammaridae, have been investigated for the presence of helminth parasites. G. fossarum reproduces throughout the year in the area near Lyon, but fluctuations in the rate of ovigerous females appear. A peak in the infestation of the gammarids by larvae of Pomphorhynchus laevis (Acanthocephala) occurred in autumn and a second peak, but a lower one, during spring. The fish hosts showed maximal...

The main task of the first directors of the Rijksherbarium consisted of the preparation of a catalogue of its Dutch East Indian and Japanese collections (cf. van Steenis-Kruseman’s paper in this volume). Among those who contributed to this catalogue was J. H. Molkenboer, a young physician who had graduated on a botanical thesis in 1840. From that year until 1846 he worked on vascular plant collections of the Rijksherbarium and got permission from its director (C. L. Blume) to devote part of his time to bryophytes. He sorted and arranged the Asian collections and started their identification together with his friend and colleague F. Dozy. In 1844 their first precursory paper appeared (‘Muscorum frondosorum novae species ex archipelago indico et Japonia’)....

Gagea lutea (L.) Ker-Gawl. is a rather rare species in the eastern part of the Netherlands, occurring chiefly in the so-called Drenthian and Subcentral European districts; besides, it is recorded from some findspots in the province of North-Holland (fig. 1).

A selected number of specimens is cited; a full list of collectors will appear in the series Identification Lists of Malesian Specimens. Bleekeria Hassk. and Excavatia Markgr. are reduced to Ochrosia. In the note under Ochrosia there is a full discussion of the differences between this genus and Neisosperma, especially of the fruit for which some old types were microscopically examined. In Ochrosia the fruits are apocarpous, but in one species they are connate for one third, while in a new species from Flores they are united into a syncarpous, 2-celled drupe. In spite of the...

Amsterdam expeditions to the West Indian Islands, Report 2. New data on taxonomy and zoogeography of ingolfiellid Crustacea
Provedor de dados: Naturalis Digital Academic Repository
Autores: Stock, Jan H.
Groundwaters (in wells, springs, caves, macroporous interstitia...) of 29 Caribbean islands have been investigated. Only on the four islands off the coast of Venezuela (viz., Aruba, Curaçao, Bonaire, and Margarita) members of the suborder Ingolfiellidea (Crustacea, Amphipoda) have been encountered, altogether six species, of which three are described here for the first time. The zoogeographical implications of this limited range in the West Indies is discussed.

Flowers and fruits in Flacourtiaceae. IV. Hydnocarpus spp., Kiggelaria africana L., Casearia spp., Berberidopsis corallina Hook. F
Provedor de dados: Naturalis Digital Academic Repository
Autores: Heel, W.A. van.
In Hydnocarpus the hard layers of the seed coat develop from the epidermides of both integuments where they are contiguous. This does not conform with the division of the Angiosperm seeds into testal or tegmic. Corner’s suggestion of two unallied groups in the Flacourtiaceae, namely an integumental and a pachychalazal one, cannot be corroborated. The seeds of Kiggelaria closely resemble those of Hydnocarpus. In Casearia the development of the fruit wall and its vascular bundles is different for the Asian and the American species studied. The three parietal placentae are confluent over the base of the ovary. The seeds are exotegmic, as described by Corner; the ovules are atropous. The berries and seeds of Berberidopsis are described for the first time. The...

Fascicles of Flora of India. The first fascicle of this new Flora of India was issued by the Botanical Survey of India in 1978. It contains the treatment of Coriariaceae (2 sp.) and Paeoniaceae (1 sp.), both by Dr. M.A. Rau, in all 8 printed pages, each family illustrated by one full-page plate. The treatment is the usual one in a Flora, with descriptions and keys, synonymy etc., in a concise form, the descriptions occupying 6-9 lines of print. Headings under each species are: citation of the type, flowering and fruiting months, distribution, uses, chromosome numbers, and notes. There is a lamentable lack of any entry on ecology (except altitude and flowering &amp; fruiting time).

Wood anatomy of the Combretaceae
Provedor de dados: Naturalis Digital Academic Repository
Autores: Vliet, G.J.C.M. van.
The wood anatomy of all genera of the Combretaceae (Meiostemon excepted) is described in detail on the basis of 120 samples representing 90 species from 19 genera. Additional data from the literature are added. The structural variation of the vestured pits is described and classified. There are two main types, of which the distribution follows the subfamily classification. Considering the overall wood anatomy, the recognition of two subfamilies: Strephonematoideae (Strephonema only) and Combretoideae (all remaining genera) can be supported. Strephonema stands out on account of its fibre-tracheids, type of vesturing and parenchyma distribution pattern. Within Combretoideae, one group of genera (subtribe Combretinae sensu Exell &amp; Stace) stands out...

The paper published 1963 by Illies &amp; Botosaneanu on “Problems and methods of the classification and ecological zonation of running waters”, has attracted the attention of many hydrobiologists working on running waters; rather many of them used the system of longitudinal (vertical) zonation in their own studies, or/and critically discussed this method. An attempt is here made to critically review almost the entire bibliography on the subject published these last 15 years (about 50 titles). This review shows that meanwhile the theory of zonation has significantly developed, that it has vigorously stimulated research and discussion in different parts of the world, and that it is partly responsible for the progress achieved these last years by the...

Palaeobiology of Tetragonis sulcata d'Eichwald, 1860 : an Ordovician receptaculite in erratics from the northern Netherlands
Provedor de dados: Naturalis Digital Academic Repository

A study has been made of the receptaculite Tetragonis sulcata d'Eichwald, 1860 in Upper Ordovician erratics from the northern Netherlands. D'Eichwald's original description is reviewed, giving a wider conception of the morphological diversity of receptaculites. Tetragonis sulcata is placed in the family Tetragonaceae Rietschel, 1969 (nomen correctum), together with Lepidolites dickhauti Ulrich, 1879. The aim of this study was to reconstruct the living receptaculite organism by documenting homologies between Tetragonis sulcata and receptaculites described in the literature. Through analysis of a diverse set of morphological features which thus were obtained, an attempt could be made to determine the pattern of receptaculite morphogenesis. This study...

Notes on the Hyadesia species (Acari, Astigmata, Hyadesidae) of the Oudemans collection, with a redescription of Hyadesia Vietsi Womersley, 1961
Provedor de dados: Naturalis Digital Academic Repository
Autores: Fain, A.
INTRODUCTION The mites of the genus Hyadesia are of cosmopolitan distribution. They live in the intertidal area where they feed mainly on algae in salt water. Up to now 16 species have been described in this genus. Most of these species have been inadequately described and it is generally very difficult to recognize them from the original description and figures. Through the courtesy of Dr. L. van der Hammen of the Leiden Museum, we were able to examine the hyadesid mites conserved in that Museum. The present paper is devoted to the study of this collection. It allows us to redescribe Hyadesia vietsi Womersley, 1961, and to record some new localities for Hyadesia fusca (Lohmann, 1894). Hyadesia vietsi Womersley, 1961 (figs. 1-7) This species is known after...

Autecology of shallow-water Octocorallia from Mediterranean rocky substrata, I. The Banyuls area
Provedor de dados: Naturalis Digital Academic Repository
Autores: Weinberg, Steven.
The autecology of eleven mediterranean octocoral species (3 Stolonifera, 4 Alcyonacea, 4 Gorgonacea) was studied near Banyuls-sur-Mer (southern France). Field observations were carried out by means of SCUBA-diving in forty underwater stations. The ecological amplitude of each species was determined for a number of abiotic factors, viz. water temperature, submarine irradiance, water movement, slope of substratum and sediment. In this way the ecological niche for the different species was defined. The niches of several species partly overlap: the survival “strategy” of these species was defined as “competitivity”. Other species display “specialization”, a strategy by which they avoid competitive situations. A third survival mechanism is “opportunism”,...

Provedor de dados: Naturalis Digital Academic Repository
Autores: Gaudant, J.
The revision of the fish fauna from the Tiglian of Tegelen (The Netherlands) allows the improvement of our knowledge of this fossilbearing locality. Eleven genera of freshwater fishes have been recognized. Their association enables one to define the deposition conditions under which the clayey sands were deposited in the upper part of the Tiglian Stage. It is clearly shown that these deposits have been laid down by slowly moving waters. The climate does not appear to have been strikingly different from the recent one of The Netherlands.

This is the first flora of macromycetes published for Mexico. The first part of it contains rather elaborate keys to nearly 600 species; the second part illustrations of all species treated, partly as line-drawings, partly as black-and-white photographs (often more than one per species). The variation of fungi represented reflects the great ecological diversity of Mexico. A list of Mexican names of fungi and lists of edible, poisonous, hallucinogeneous and wood-destroying fungi are added, as well as a Spanish glossary. The disadventage of the lack of microscopical characters in the keys is partly compensated by the presence of numerous illustrations.

Provedor de dados: Naturalis Digital Academic Repository
Autores: Koek-Noorman, J.; Hogeweg, P.; Maanen, W.H.M. van; Welle, B.J.H. ter.
The present paper deals with the wood anatomy of the Blakeeae (Melastomataceae). Generic descriptions of the secondary xylem of Blakea, Topobea, and Huilaea are given and compared with data on 16 genera of the Miconieae. Numerical pattern detection was undertaken. The results confirm our preliminary ideas that Blakea and Topobea do not differ enough to enable the separation of these genera on the basis of their wood anatomy. Within the Miconieae it is not possible to separate the genera. However, some anatomical differences between the two tribes were found. The genus Huilaea seems to belong in the Blakeeae although it also shows similarities with the Miconieae. Wurdack’s suggestion (pers. comm.) that the Blakeeae are closest to the genera Loreya and...

There Reinwardt, founder of the Botanical Garden of Buitenzorg (now Bogor, Indonesia), was professor since 1821. There the State Museum of Natural History had been founded in 1820. There was also situated the old and famous Hortus Academicus with which also Von Siebold had his contacts while in Japan and which was the destination of a large shipment of live plants he had brought with him.

This paper concerns the genus Boophis Tschudi, 1938 ( = Malagasy Rhacophorus Kuhl &amp; Van Hasselt, 1822). Apart from a reconsidering of adult morphology, certain new taxonomic characters, such as the colouration in life, the morphology of the tadpole and some mating calls, are presented. Karyotypes and nuclear DNA amount were reported upon elsewhere. This study produces a sharper definition of the endemic genus, permitting its clear separation from the genus Mantidactylus Boulenger, 1895. Various sibling species are reported; as a result different synonymies are revised and new species presented. Four new species are described, viz.

Nietzsche’s reception of Darwinism
Provedor de dados: Naturalis Digital Academic Repository
Autores: Mostert, Pieter.
It has been generally assumed that the influence of Charles Darwin's theory of evolution on Friedrich Nietzsche (1844- 1900) is to be understood in terms of Nietzsche's concept """"Obermensch"""" (overman). Hardly any attention has been paid to the question of the status of Darwin's theory in Nietzsche's philosophy. It is the purpose of this essay to answer that question. Nietzsche's initial approval, and later criticism, of Darwinism is not limited to a specific theme of his philosophy, but is a part of his central philosophical concern, viz. the relation between nature and culture. Nietzsche approved of Darwin's theory as a natural basis for the explanation of human values. Later he is concerned about the basis of Darwin's theory and criticizes it...

The wormsnakes (family Typhlopidae) of the Neotropics, exclusive of the Antilles
Provedor de dados: Naturalis Digital Academic Repository
Autores: Dixon, J.R.; Hendricks, F.S.
The systematic arrangement of the worm snakes (Typhlops) from the continental western hemisphere is presented. Allocations of many names historically assigned to Central and South American Typhlops are clarified. The continental Typhlops include nine species, two of which are described as new. The intraspecific variation of all species is explored within the limitations of known specimens. Three major radiations of New World Typhlops are postulated to account for the radiations of the present species groups.

Droge stroomdalgraslanden langs Maas en Niers

Autores: Sykora, K.V.; Westhoff, V.
The grasslands characteristic of dry sandy soils found along rivers in the nature reserves Zelderse Driesen and Rivierduintjes bij Mook have been investigated by means of the Braun-Blanquet method. Whereas a community with high species diversity is still found in the Zelderse Driesen, the plant cover of the Rivierduintjes bij Mook has lost all the stenotope species characteristic for the lower syntaxonomic units, due to intensive recreation and the absence of summer grazing. Such a community containing only character species from higher phytosociological units as well as accompanying species has been called a basic community (Basalgesellschaft; KOPECKÝ &amp; HEJNÝ, 1974). As the word ‘basic’ suggests an original and fundamental situation, while the term...

Allium paradoxum (Bieb.) G. Don aan de binnenduinrand inburgerend

Allium paradoxum, a native of S.W. Asia and naturalized for over a century in Britain, Germany and Czechoslovakia, has also established itself at some localities in the Netherlands. In some woodlets on the inner side of the dunes near Heemstede and Bloemendaal (prov. of Noord-Holland) it is locally abundant, being known from these findspots since c. 1918 and 1957 respectively. Moreover, the species was recorded from similar localities near Wassenaar and Oostvoorne (prov. of Zuid-Holland), but on the former spot it has vanished possibly due to human activity and on the latter it has not spread very much thusfar. It is the author’s opinion that A. paradoxum should be considered a member of the Dutch flora because of its naturalizing on at least two...

In the present paper Hyla ornatissima Noble is removed from the synonymy of Hyla granosa Boulenger, and resurrected as a separate species on the basis of morphological, ecological and acoustical differences. Another relative of this group occurring in Guiana is Hyla sibleszi Rivero. Because of its superficial resemblance with these frogs Hyla punctata (Schneider), of another species-group, is also treated. All four species are extensively described, data on life history and distribution are given. H. sibleszi, so far only known from the type material and some associated specimens, is reported from several new localities in Venezuela and Guyana. It is suggested that the function of the intricate dorsal pattern of H. ornatissima serves to protect the animal...

Autores: Cuppen, J.G.M.
Ranunculus hederaceus which is rare in the Netherlands has been found in six hour-squares in the province of Limburg. The species seems to be restricted to small, 0—25 cm deep ditches with stagnant or usually very slowly flowing water. At some places the plants are covered with ironhydroxide due to seepage of ground water. It is essential for the maintenance of Ranunculus hederaceus vegetations that the ditches will be cleaned once a year in autumn, otherwise Ranunculus will be overgrown by grasses, e.g. Glyceria fluitans.

The caddis-flies (Trichoptera) of Cuba and of Isla de Pinos: a synthesis
Provedor de dados: Naturalis Digital Academic Repository
Autores: Botosaneanu, L.
Even a few years ago, the caddis-fly fauna of Cuba remained very poorly known. The situation notably improved, especially following the study of collections made throughout the Island, either by myself, or by Cuban entomologists (Botosaneanu &amp; Sykora 1973, Botosaneanu 1977, Botosaneanu in press). At present, somewhat less than 80 species and subspecies are known from Cuba (2 Rhyacophilidae Hydrobiosinae, 8 Glossosomatidae Protoptilinae, 6 Philopotamidae, 1 Psychomyiidae Xyphocentroninae, 6 Polycentropodidae, 6 Hydropsychidae Hydropsychinae and 3 Macronematinae, 31 Hydroptilidae, 3 Leptoceridae, 2 Odontoceridae, 4 Calamoceratidae, 5 Helicopsychidae).

Checklist of the Savanna inhabiting frogs of the El Manteco region with notes on their Ecology and the description of a new species of Treefrog (Hylidae, Anura)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hoogmoed, M.S.; Gorzula, S.J.
Three years of fieldwork in the El Manteco region by the junior author formed the basis for the checklist presented here. Among the frogs assembled is a small species of Ololygon, new to science, also found in Guyana and Surinam. The anuran succession in the temporary lagoons, formed during the rainy season, was studied during three years and a consistent pattern was found. Comparisons with the llanos fauna are made and it is concluded that the El Manteco region contains a relatively large percentage of Amazonian elements, absent from the llanos.

Ultrastructure des hyphes incrustées dans le genre Skeletocutis
Provedor de dados: Naturalis Digital Academic Repository
Autores: Keller, J.
The incrusted hyphae of all species of the genus Incrustoporia (1963) have the same very typical ultrastructure, with the exception of those of I. carneola. Consequently the last-named species is to be reinserted in Poria. The crystallizations on the hyphae of S. amorpha, the type species of the earlier generic name Skeletocutis (1958), are of the same sort. Therefore Incrustoporia has to merge into Skeletocutis, and the following new combinations are proposed: Skeletocutis alutacea, S. nivea, S. percandida, S. stellae, S. subincarnata, and S. tschulymica.

Pycnogonida from the mediolittoral and infralittoral zones in the tropical western Atlantic
Provedor de dados: Naturalis Digital Academic Repository
Autores: Stock, Jan H.
Twenty-seven species of Pycnogonida are recorded from the mediolittoral and infralittoral zones in the West Indies and of the north coast of South America, including two new species. Eurycyde acanthopus n. sp. was found on the shelf off the coast of Venezuela. Anoplodactylus monotrema n. sp. is widely distributed in the area; it has apparently been confused in the past with A. robustus (Dohrn, 1881). The morphology of the latter, and of the closely related A. virescens (Hodge, 1864), is discussed. Material from Amsterdam and St. Paul islands (Indian Ocean) attributed to A. virescens, is considered to belong to a separate species, A. dentimanus. – The range of several species is extended.

In the present appendix four lists are given: books, serials, doctor’s theses, papers on the institute. A large proportion of the scientific output, viz. the papers published in journals, have consequently not been mentioned although some of them are more voluminous than many books. Not mentioned either are the reports written by students.

Type studies on entolomatoid species in the Velenovský Herbarium—I. Species described in the genera Nolanea, Leptonia and Telamonia
Provedor de dados: Naturalis Digital Academic Repository
Autores: Noordeloos, M.E.
All types of entolomatoid fungi available in the Velenovský Herbarium at Prague have been studied. In this first report the types of 30 species described by Velenovský in Nolanea, Leptonia and Telamonia (one species) are described. Species accepted here have, if necessary, been transferred to Entoloma, which resulted in 18 new combinations and 4 new names. One described in Nolanea had to be transferred to Pluteus.

Voorkomen en standplaats van Veronica praecox All. en V. verna L. in Nederland
Provedor de dados: Naturalis Digital Academic Repository
Autores: Weeda, E.J.
A few years ago, Veronica praecox en V. verna were supposed to be extinct in the Netherlands, being recorded for the last time in 1935 and 1947, respectively. In 1974 both were refound, however. Formerly, V. praecox occurred on arable land in the Yssel valley in the surroundings of Deventer and at some localities south of Maastricht. The latter connect with localities in Belgium; the former constitute a kind of ‘outpost area’ northwest of the border of the species’ serried area. Possibly V. praecox, together with a few other species, can be looked upon as a ‘xerothermic relic’ there. Its habitat on the only recent locality near Gorssel (south of Deventer), where in the vicinity of V. praecox amongst others Vicia lathyroides, Saxifraga tridactylites and...

The systematic position of Olindia and Isoτrias (Lepidoptera, Tortricidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Razowski, J.
Until present the Palaearctic genera Olindia Guenée and Isotrias Meyrick have been placed either in the tribe Cnephasiini or in the Archipini. However, the study of the male genitalia reveals that they actually belong to the Polyorthini, the group known till now only from the subtropical and tropical regions of Asia, Australia and America. Both Olindia and Isotrias are characterised by well developed longitudinal split of the outer surface of the valva in which a rather delicate bunch of hair-like scales is situated. This bunch originates laterally in the median area of the subgenital segment but is derived from the tergite. This is a specialised character of the present tribe, reduced secondarily in a single Asiatic genus Cnephasitis Razowski only...

The life cycle of a gorgonian: Eunicella singularis (Esper, 1794)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Weinberg, Steven; Weinberg, Francisca.
The life cycle of the gorgonian Eunicella singularis has been studied with emphasis on larval behaviour, metamorphosis and annual growth. Planulae are found to have a mobile phase lasting from several hours to several days. Once settled, they metamorphose into a complete primary polyp in approximately four days. In the first year, budding will yield colonies of a height between 10 and 30 mm. Subsequently, average growth rates range from 14 to 33 mm year¯¹. Death may be due to several causes. Predators may partly denude the gorgonian branches, thus facilitating the settlement of epibionts, which in turn may invade the entire skeleton, slowly pushing back the living tissue of the gorgonian. Colonies may also be torn off their substratum by wave or current...

Statistical reconstruction of the Palmatolepis apparatus (Late Devonian conodontophorids) at the generic, sub-generic, and specific level
Provedor de dados: Naturalis Digital Academic Repository
Autores: Boogaard, M. van den; Kuhry, B.
Extensive frequency data are used for a reconstruction of Devonian cunodont apparatuses. Correspondence analysis and a related clustering method are selected as statistical tools, and are used as informal methods for testing a priori hypotheses rather than as search mechanisms. In our view, the Palmatolepis apparatus consists of palmatolepan P elements, tripodellan or nothognathellan O elements, palmatodellan and smithiform N elements, and a symmetry transition consisting of falcodontan A1 elements, asymmetrical scutulan A2 elements, and symmetrical scutulan A3 elements. A peculiar phenomenon, already described by other authors, is the numerical dominance of the P elements, which are on the average 15 times as frequent as corresponding O and N elements. It...

Deux Hydropsyche nouveaux du Jourdain (Trichoptera, Hydropsychidae)

Autores: Botosaneanu, L.
Two new Hydropsyche-species from the Jordan River are described; they belong to the guttata-group, and at least one of them was regularly confused with the West European H. exocellata Duf. H. batavorum sp.n. is an apparently rare species, whose phallus shows features never recorded at least for the guttata-group. H. janstockiana sp.n. is much more abundant, and it is obviously nearly related to H. sciligra Mal. (Caucasus, Iran, Asia Minor, Central Asia). Both are certainly potamobionts whereas the third Hydropsyche of the Jordan River System ( H. jordanensis Tjeder. belonging to the instabilis-group) seems to be rather a rhithrobiont.

Herbals and herbaria for scientific purposes have been made from the 16th century. They were private property long before the time of the foundation of most institutional herbaria, in which they are now, as far as they are still intact, preserved. The oldest, when in book-form, are of course kept apart. Those mounted on loose sheets were treated in different ways and were subsequently incorporated and filed in the general herbarium, as for instance those of Van Royen at Leiden, Burman f. at Geneva, R. Brown at the British Museum and the Hooker and Bentham collections at Kew. In other instances they were kept apart and preserved as a separate unit, in view of the fact that they represented the authentic standard works of authorities, for example the...

The Rijksherbarium and its contribution to phycology
Provedor de dados: Naturalis Digital Academic Repository
Autores: Prud’homme van Reine, W.F.; Lokhorst, G.M.
In modern handbooks the development of plant systematica is given as occurring in four overlapping phases: the pioneer (or exploratory) phase, the consolidation phase, the biosystematic phase, and the encyclopaedic phase. In systematic phycology research is still largely in the pioneer phase, with scattered attempts to reach the second, third, or even fourth phase. In many cases in phycology the biosystematic phase has to precede the consolidation phase. Knowledge of algae (growing mainly in marine or freshwater environments, but also occurring in soils or snow and on rocks or trees) is quite scanty in most parts of the world, and even for taxa that are supposed to be well known, the information is often but fragmentary. The encyclopaedic phase is for most...

A pinewood of 173 ha in the municipality of Arnhem was destroyed by fire on July 7, 1976. In the spring of 1978 and 1979 about 82 ha of this terrain was planted with broadleaves and conifers. As an experiment to increase the moisture retention capacity and to hinder the settlement of weeds, a layer of 10 cm of chipped tree bark was strewed. The chipped bark came from the Netherlands, Belgium, Germany and Scandinavia. During a floristic inventory of the terrain in the summer of 1979 more than 300 wild plant species were found, many of them rare or even unknown in the Netherlands. Almost all these species were found on the part covered with tree bark. Presumably the seeds of many species were introduced with the tree bark. It seems worthwhile to follow the...

Competition Between Plant Populations with Different Rooting Depths I. Theoretical Considerations
Provedor de dados: Naturalis Digital Academic Repository
Autores: Berendse, Frank.
As an extension of De Wit’s competition theory a theoretical description has been developed of competition between plant populations with different rooting depths. This model shows that in mixtures of plants with different rooting depths the value of the Relative Yield Total can be expected to exceed one. Moreover, it predicts the frequency-dependence of the relative crowding coefficient of the deep rooting population with respect to the shallow rooting population. The relationship between properties of plant species and the environment required to establish a stable equilibrium turns out to be surprisingly simple. The shallow rooting species has to have a larger competitive ability sufficient to compensate for the extra nutrients that are exploited by the...

Biology and infestation rate of Corallonoxia longicauda, an endoparasitic copepod of the West Indian reef coral Meandrina meandrites
Provedor de dados: Naturalis Digital Academic Repository
Autores: Butter, Maureen E.
During 1½ year the biology of Corallonoxia longicauda, a copepod endoparasitic in the stony coral Meandrina meandrites was studied in Curaçao, Netherlands Antilles. The infestation rate of the corals as well as the numbers of parasites present were investigated at several depths and in several stations. The parasites proved to be distributed in a spatial pattern inside the colony. This pattern appeared to be correlated with current and exposure. It is postulated that the numerical distribution of the copepods in the corals, which differs markedly from a normal distribution, depends on the way of proliferation and settling of the parasites. This offers also an explanation for the remarkable spatial pattern inside the colony. The results of the comparison of...

„Stinse plants” are species (almost) exclusively limited in their distribution within a certain area to old countryseats („stinsen”) and related habitats as churchyards and old ramparts. Besides introduction by man also the specific habitat of these plants is an important factor: a fertile, moist and often calcareous soil, in the past manured and dug by man. Attention is paid to the natural habitats in Germany and France of stinse plants, especially Corydalis bulbosa. These habitats are dynamic environments such as the lower parts of slopes and along brooks in woods. Close to these places also anthropogenic habitats occur: in woods along arable land, on disturbed soil, in banks along a road, under hedges etc. Here the natural environmental dynamics are...

In Memoriam Jan G. Sloff en Prof. Dr. D. Bakker
Provedor de dados: Naturalis Digital Academic Repository
Autores: Mennema, J.; Adema, F.
In een kort tijdsbestek heeft floristisch Nederland twee prominenten verloren: op 1 februari j.l. overleed op 86-jarige leeftijd te Bergen op Zoom Jan G. Sloff, op 12 maart j.l. op 61-jarige leeftijd te Groningen Prof. Dr. D. Bakker. De verdiensten van beiden voor de Nederlandse floristiek zijn eigenlijk te veel omvattend om in deze beperkte ruimte naar behoren gestalte te geven. De naam van Jan G. Sloff zal onverbrekelijk verbonden blijven met het IVON (Instituut voor het Vegetatieonderzoek van Nederland). Als vertegenwoordiger van de Kon. Ned. Botanische Vereniging was hij in 1930 mede-oprichter om in 1933 tot secretaris van dit instituut te worden benoemd. In die functie heeft hij onvoorstelbaar veel werk verzet in de vorm van het inventariseren van de...

Sri V.S. Agarwal became Editor of Publications, CAL Herbarium. Dr. P.S. Ashton of Aberdeen has taken up his duties as Director of the Arnold Arboretum, Arnold Professor of Botany and Professor of Dendrology, after some delay because it had been ascertained that while in Malaysia he had led a crimeless life. That Harvard thus strengthens its interest in the Malesian plant world is very welcome news. His MS on Dipterocarpaceae for Flora Malesiana is ready for the press except for the illustrations, which are now being prepared at Leiden.

Amsterdam Expeditions to the West Indian Islands, Report 6. Arubolana imula n. gen., n. sp., the first hypogean cirolanid isopod crustacean found in the Lesser Antilles
Provedor de dados: Naturalis Digital Academic Repository
Autores: Botosaneanu, Lazare; Stock, Jan H.
Arubolana imula, a new stygobiont isopod genus and species of the family Cirolanidae is described from Aruba (Netherlands Antilles). The new taxon has been discovered in an artificial tunnel, used for the production of industrial water, cut into calcareous rocks from marine origin which were rather recently uplifted above sea level (90,000-500,000 years B.P.). This is the first hypogean cirolanid that becomes known from the Lesser Antilles. The quite characteristic and simplified morphology of the posterior maxillae and maxillipeds, the subterminal position of the appendix masculina, and the prehensile nature of the first and second pereiopods, distinguish the new genus very clearly from all other hypogean genera in the family Cirolanidae. The feeble...

Notes on Southeast Asian Porcupines (Hystricidae, Rodentia). IV. On the taxonomy of the subgenus Acanthion F. Cuvier, 1823 with notes on the other taxa of the family
Provedor de dados: Naturalis Digital Academic Repository
Autores: Weers, D.J. van.
Arguments are presented to demonstrate that Lyon’s (1907) division of the Old World porcupines, family Flystricidae, into two subfamilies is superfluous and provides a distorted classification. Evidence is presented for the point of view that the generic status of Thecurus Lyon, 1907 has been based on quite insufficient arguments, and this taxon is not accorded a higher rank than that of a subgenus. Only three genera are recognized in this family: Trichys Günther, 1877, Atherurus F. Cuvier, 1829, and Hystrix Linnaeus, 1758 with the subgenera Hystrix s.s., Acanthion F. Cuvier, 1823 and Thecurus Lyon, 1907. Data about some south-western Asiatic specimens of Hystrix indica Kerr, 1792 are presented. The main subject of the present paper is the specific...

Mycology and lichenology at the Rijksherbarium
Provedor de dados: Naturalis Digital Academic Repository
Autores: Brummelen, J. van.
Soon after the foundation of the Rijksherbarium in 1829 King Willem I of the Netherlands presented the herbarium of C. H. Persoon to this institute. The fungi in this famous herbarium, along with some other collections, among which the tropical fungi collected by F. W. Junghuhn and H. Zollinger, formed the basis for the mycological herbarium. But in the early period of the Rijksherbarium, owing to a shortage of funds and the absence of a curator for the cryptogams, the collections of fungi and lichens were badly neglected and remained in disorder for a long time. It was the third director of the Rijksherbarium, W. F. R. Suringar (director from 1871 to 1898) who became aware of the omissions in the collections of cryptogams and who took measures to fill the...

Domatia in seedlings
Provedor de dados: Naturalis Digital Academic Repository
Autores: Brouwer, Yvonne M.
In recent years considerable interest has been taken in the characteristics of seeds and seedlings, especially those of rainforest species. The rapid destruction of the world’s rainforests is the cause of great concern to many. Efforts at rehabilitation and reafforestation can be assisted considerably if seedlings can be readily recognised and their ecological requirements ascertained. Many botanists such as Duke (1965, 1969) and Burger (1972) are endeavouring to add information on this aspect of rainforest ecology. Systematic botanists also find characters of seedling morphology and anatomy useful as evidence of relationships at various levels of taxonomy, and also in some cases, Bailey (1956), as evidence in phylogenetic studies. One character which...

Taxonomy and zoogeography of Dobsonia Palmer, 1898, from the Louisiade Archipelago, the D’Entrecasteaux Group, Trobriand Island and Woodlark Island (Mammalia, Megachiroptera)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bergmans, Wim.
A lectotype is selected — and its skull figured, for the first time — for Dobsonia pannietensis (De Vis, 1905), which is considered to be a good species. Specimens have been examined from the Louisiades, the D’Entrecasteaux Group, Trobriand Island and Woodlark Island. The species varies per island or island group in dimensions and/or proportions. The skull of the holotype of Dobsonia remota Cabrera, 1920, is figured — also for the first time. The possible synonymy of this species with D. pannietensis is discussed. The holotype, from Trobriand, is still the only known specimen. Specimens from Bougainville, Solomon Islands, referred to remota by McKean (1972), are in fact juvenile Dobsonia inermis Andersen, 1909.

The collections of Pteridophytes at the Rijksherbarium
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hennipman, E.
Since the foundation of the Rijksherbarium, pteridophytes have been an important part of the total collections. Blume, the first director, had a special interest in ferns. In 1826, when he returned to Europe from his stay in Java, he took with him large collections of well preserved pteridophytes which he had gathered there himself. These, together with the fern collections of Van Hasselt, Kuhl (both from Java), and Zippel (Java, Moluccas, New Guinea), were all deposited in the Rijksherbarium. Blume’s studies on the ferns of Java, both in the wild and in the herbarium, were published before the foundation of the Rijksherbarium in the second fascicle of the ‘Enumeratio Plantarum Javae et insularum adjacentium minus cognitarum vel novarum’ (1828) in which...

In the period 1973-1978 members of the Institute of Taxonomic Zoology (Zoölogisch Museum) have sampled the non-marine fauna of 27 West Indian islands. The present report records the stations in which stygobionts (= groundwater organisms) were collected . The main purpose of the program was to test the value of various biogeographic models for explaining the insular fauna. Since in general the fauna of inland waters yields good results in biogeographic analyses, the program was mainly directed to this fauna.

Morphology at the Rijksherbarium
Provedor de dados: Naturalis Digital Academic Repository
Autores: Heel, W.A. van.
In the following the role of morphology, anatomy and palynology in systematics at the Rijksherbarium will be discussed, as far as flowering plants are concerned. It will be demonstrated that most of the research in this field is rooted in the interest of individual workers, and that no planning was involved until recently. The scope of it varied, as it was done either for pure taxonomic purposes, or for systematic and phylogenetic reasons, or for its own merit. Chiefly, I think, the study of morphology s.l. originated because Suringar, Hallier, Lotsy, and especially Lam, were interested in achieving a more natural or evolutionary system of the Angiosperms. Lotsy and Lam extended their interest to the other Cormophytes as well. In 1895 W. F. R. Suringar...

Our 150th anniversary is commemorated in a rather modest way and it is not our intention to make it an important international event. Hoewever, we decided to dedicate part of Blumea to the jubilee, not only in order to bring our anniversary to the attention of our colleagues abroad, but also in order to bring the historiography of our institute more or less up to date. The last time the history of the Rijksherbarium was written, was on the occasion of the 100th anniversary of its residence in Leiden. The conservator W. A. Goddijn then published a rather lengthy paper in Dutch and a short summary in French, in the Mededeelingen van’s Rijks Herbarium, nr. 62a/b, 1931.

Now that at the Jakarta Forestry Congress it was announced on the behalf of the Indonesian government that a target area has been set to conserve 5% of the land area, eventually to be increased to 10%, the time has come to indicate how these areas are to be allocated. Botanical arguments are available as a guidance; they are drawn from established sources, including experience from work at the Rijksherbarium. A number of points are here given. 1. In Malesia, it is usually possible, clearly to distinguish between primary forest: rich in species, balanced as an ecosystem, complex, fragile, different from place to place, in which rarity of species prevails, slow in regeneration, irreplaceable within any foreseeable amount of time, and secondary forest: poor...

A study, by immunoelectrophoresis and immunodiffusion of the shared antigens in venom from 21 species of Viperinae and Crotalinae, representing 10 different genera, has produced a number of results of taxonomie significance which are summarized schematically in the dendrogram shown in fig. 1. For the most part these immunological data confirm the accepted classification of the Viperidae which is based on comparative morphology and biogeography. Some results, on the other hand, such as the isolated position of Atheris, need confirmation with more material. Some of the conclusions reached in this study, however, appear to be of significance for an understanding of the phylogeny of the group.

Jackiopsis, a new name for Jackia Wall. (Rubiaceea – Jackieae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Ridsdale, C.E.
Jackia, published by Wallich, in 1824, is a well-known genus of uncertain tribal position within the Rubiaceae. Unfortunately there is an earlier, overlooked, genus published by Blume commemorating W. Jack (1795 – 1822). This has been cited in Index Kewensis 1 (1895) 1245 as being published in 1825, but the correct date is 1823 as indicated on the cards of the Index Nominum Genericorum. Blume (1823) consistently used the spelling Jakkia’; however, in 1825 he altered the spelling to ‘Jackia’ and added further species to the genus. Thus, it cannot be argued according to article 73 of the Code that Blume misspelled the latinized name of Jack. Jakkia and Jackia are to be treated as orthographic variants according to article 75 of the Code. Airy Shaw in Willis,...

Cavernicolous And Terrestrial Decapod Crustacea From Northern Sarawak, Borneo
Provedor de dados: Naturalis Digital Academic Repository
Autores: Holthuis, L.B.
During the 1977-1978 Royal Geographical Society Mulu (Sarawak) Expedition a number of Decapod Crustacea was obtained. Some were collected by Mr. Philip Chapman in the course of studies of the invertebrates of the limestone caves in the Gunong Mulu National Park, 4th Division of Sarawak, and the Niah National Park south of Miri. Another expedition member, Dr. N. M. Collins, collected several crabs in pitfall traps and one in a soil core in the course of studies of terrestrial invertebrates of the Mulu area. I am most indebted to Messrs Chapman and Collins for placing this interesting collection of cavernicolous and terrestrial Decapoda at my disposal, and for the extensive information on the localities, habitats and the biology of the species, as well as...

Enkele minder algemene en gespecialiseerde Chlorophyceae uit een trilveen in het natuurreservaat de Weerribben (NW.-Overijssel)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Schreijer, M.
Algological studies were carried out in a quivering bog in the marshy region of N.W. Overijssel, microscope slides being used as an artificial substrate. A number of ecologically specialised taxa not previously or only rarely recorded from the Netherlands were encountered. The species in question appeared especially during the initial stages of the settling of life forms on the slides. Most of them have hair-like appendages in the form of bristles (setae) or pseudocilia. Conceivably such protruding appendages have a deterrent function in connection with their apparently low competitive power. Among these species, Coleochaete scutata forma minor, Chaetopeltis orbicularis, and Chaetosphaeridium pringsheimii are the commonest and seem to have a relatively...

Carduus crispus L., neofiet in Twente
Provedor de dados: Naturalis Digital Academic Repository
Autores: Weeda, E.J.
This paper deals with the occurrence of Carduus crispus in Twente, the eastern part of the province of Overijssel. Whilst in the greater part of the Netherlands this thistle has been recorded for a long time, in Twente it is a rather recent arrival. Up to some fifteen years ago it was chiefly recorded incidentally in scattered localities; only in the town of Hengelo it was found as early as 1895 and is still present there. Recently, C. crispus has established itself over a long stretch along the small river Dinkel (fig. 1); besides there are some stable stations along railways. Its occurrence is restricted to substrata considerably influenced by men.

Description of the process of colour change in the fur of a female White-cheeked Gibbon from the juvenile black coat to the light adult coat, starting at the age of 7V2 ar&gt;d finishing at 8I/2 years. The birth of the first young occurred when the female had attained the age of barely 9 years, and of the second 2*/2 years later. The progress of colour change of the first-born female young from the light infant fur to the dark juvenile fur, starting at the age of 9 months and finishing at the age of IV2 years, is described as well as its gradual growth of independence from the 6th/7th month up to the age of about 2 years.

Anoplodactylus ophiurophilus n. sp., a sea spider associated with brittle stars in the Seychelles
Provedor de dados: Naturalis Digital Academic Repository
Autores: Stock, Jan H.
A new species of Pycnogonida, Anoplodactylus ophiurophilus, is described. It is associated with three species of the genus Ophiocoma in the Seychelles (Indian Ocean) and constitutes the first recorded case of a sea spider found on Ophiuroidea. In comparison with the 83 species actually recognized in Anoplodactylus, the new species shows hardly any morphological adaptations due to this remarkable association.

The present memoir is the final report of a geological mapping project which has been executed by staff and students of the Department of Structural Geology of the Geological Institute of Leiden University. The project was initiated by professor Dr. L.U. de Sitter, to whom this memoir is dedicated. In the first instance this project was intended as a field training program for undergraduate and M. Sc. students, but at the same time many important contributions to the geological knowledge of this mountain chain were obtained by these students, by Ph. D. students and by staff members.

Le developpement de Limacella glioderma (Fr.) R. Maire
Provedor de dados: Naturalis Digital Academic Repository
Autores: Reijnders, A.F.M.
A comparison of the development of Limacella guttata (Fr.) Konrad &amp; Maublanc with that of L. glioderma (Fr.) R. Maire shows clearly that the latter is of a more primitive type. This conclusion is based on the following observations: a. Limacella guttata has a pileocarpic development: the first differentiation inside the primordium is that of the outgrowing and curving hyphae of the margin of the pileus; when similar hyphae appear in the primordium of L. glioderma longitudinal hyphae are simultaneously formed in the stipe. The concentrated development of the former species is moreover indicated by the pear-shaped or bulbous primordia. The primordia of L. glioderma are much more slender. b. The pileipellis of L. guttata is initiated in a very early phase...

Karyology, phylogeny and biogeography of the Namaqua chamaeleon, Chamaeleo namaquensis Smith, 1831 (Chamaeleonidae, Reptilia)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Robinson, Michael D.
The karyotype of the Namaqua chamaeleon, Chamaeleo namaquensis Smith, 1831, has 24 chromosomes consisting of 12 macro- and 12 microchromosomes. This chromosome pattern is characteristic of the C. chamaeleon (Linnaeus, 1758) species group and indicates that C. namaquensis is a member of that taxon. It is hypothesized that C. namaquensis and C. chamaeleon are the most ecologically specialized and recently evolved taxa in the chamaeleon group.

A review of the Genus Calliphara Germar, 1839 (Hemiptera: Scutelleridae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Lyal, C.H.C.
The genus Calliphara is described. Its 15 species and 6 additional subspecies are classified into 4 species-groups on the basis of the morphology of the male genitalia, and a key is provided for their separation. Calliphara solomonensis sp. nov. from the Solomon Is. and C. vollenhoveni sp. nov. from the Bismarck Archipelago are described. A synonymic catalogue of all species-group taxa within the genus is given. Fifteen lectotype designations are made. The history and relationships of Calliphara are discussed. Notacalliphara gen. nov. is founded for Calliphara rostrata Distant, and Notacalliphara pseudofasciata sp. nov. from New Guinea is described. Paracalliphara gen. nov. is founded for Calliphara flagrans (Walker).

On some Indo-West Pacific Bopyridae (Isopoda, Epicaridea) in the collections of the Zoölogisch Museum, Amsterdam
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bourdon, R.; Stock, J.H.
Four bopyrids are described. Pleurocryptina indica Nz. &amp; B. à 8., 1929, is recorded from Mauritius; it was previously known from the East Indies. Bopyrina brachytelson Nz. &amp; B. à 8., 1923, is compared with other members of the genus. Metacepon pleopodata n. sp., a parasite of Litocheira setosa collected in Amboina (Indonesia), is a species with an aberrant male morphology. Another species, parasitic on Metopograpsus oceanicus in Sumbawa (Indonesia), is tentatively attributed to Megacepon, a genus with uncertain affinities.

Un modelo estocástico de pesquerías

Autores: Gregorio, C.G.; D'Attellis, C.E.
Based on the Schaefer production model, an stochastic model is described, that is a model in which noises perturbing biomass and measurements are considered, serving to describe random variations in mortality and recruitment as well as some inaccuracies in measurements taken. The model is discrete, linear and adaptable, and the parameters biomass and noises intensities are restimated with each new measurement obtained. The problem of regulation is solved, on the basis of the model described, through fishing effort that should be applied to keep biomasss close to equilibrium. Computer effected simulations are presented.

Variaciones en la composición bioquímica proximal de la anchoíta durante tres temporadas de pesca (1975-1977)
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Moreno, V.J.; Aizpun, J.E.; Malaspina, A.M.
Seasonal variations in major biochemical compoenets (lipids, protein and water)as well as in ash content of muscle and filletin remains of Engraulis anchoita were studied separately along three consecutive fishing seasons (May-December 1975, 1976 and 1977). Five to ten adult fish of each sex and of nearly identical length (total length: 160-165 mm)were selected at approximately monthly intervals from commercial catches at Mar del Plata Harbour. During the course of the three sampling periods, the proportions of the different biochemcial components showed a very similar pattern of variation and the difference from one fishing season to another never exceeded one month.

El presente artículo da una descripción detallada de la elaboración y del "curado" de cuerdas de curricán, utilizadas anteriormente para la pesca en Taganga, un pueblo pescador en la costa norte de Colombia. Antes del "curado", estas cuerdas de fibras de algodón y de fabricación industrial, eran o destorcidas o torcidas a mano nuevamente, o tensionadas y envueltas con una cuerda más delgada del mismo material. El "curado" que siguió a estas operaciones se efectuó tanto en una cocción de corteza de las raíces zanconas de mangle, y/o por medio de un frote de estas cuerdas con los hypocotylos del mismo árbol (Rhizophora manglr). Por medio de las técnicas aquí descritas, los pescadores aspiraban a aumentar la resistencia de sus aparejos de pesca en el agua de...

Las mandíbulas secas de cuatro especies de tiburones carcharh inicios (Galeozerdo cuvieri, Carcharhinus albimarginatus, C. galapaguensis y C. porosus) del Pacífico oriental tropical fueron examinadas para determinar las tasas de remplazo dental de cada especie. En general, las tasas de remplazo fueron mayores en la mandíbula inferior que en la superior, y esta diferencia fue más grande en aquellas especies en las que la diferenciación morfológica entre los dientes superiores e inferiores es más notable. Además, las mandíbulas cuyos dientes tienden a ser más anchos que largos tienen tasas de remplazo menores que aquellas cuyos dientes tienden a ser más largos que anchos. Esto es debido posiblemente a la mayor capacidad de tensión de los dientes anchos y a...

Improvements in the decapsulation of &lt;i&gt;Artemia&lt;/i&gt; cysts
Provedor de dados: Open Marine Archive
Autores: Bruggeman, E.; Baeza-Mesa, M.; Bossuyt, E.; Sorgeloos, P.
As described in our previous paper (Sorgeloos et al. , 1977) hypochlorite can be used as reactive agent to dissolve the lipoproteic chorion of &lt;i&gt;Artemia&lt;/i&gt; cysts. Two commercial products are available worldwide, i.e. bleaching powder, chloride of lime Ca(OCL)&lt;sub&gt;2&lt;/sub&gt; and bleaching water NaOCl solutions. In Western Europe the latter product is the cheapest, whereas in the USA and Southeast Asia bleaching powder should be considered. Because the decapsulation process is a much more critical operation with bleaching powder, especially with regard to the viability of the embryos (Bruggeman et al., in preparation; Manzi, personal communication), we studied the use of technical NaOCl solutions in detail.

A previous paper by Istock, in which this author claims to have successfully applied the Lotka-Volterra model to his observations on corixid population dynamics, is criticised for the shortcomings in evidence cited to support the model's fit with the data. It is contended that the dynamic behaviour of the system of Hesperocorixa lobata - Sigara macropala interaction is not in accordance with the Lotka-Volterra model. ThIs brief critique is followed by comments by istock in reply to the points raised in Bergmans' letter.

The cycle of activity in the accessory nidamental glands from cephalopods
Provedor de dados: Open Marine Archive
Autores: Richard, A.; Van den Branden, C.; Decleir, W.
The reproductive system of female cephalopods includes a glandular system (oviduct glands and nidamental glands), which develops considerably during sexual maturation and which plays an important part in the formation of the different egg membranes. It is generally uncoloured. An exception are the nidamental glands in &lt;i&gt;Nautilus pompilius&lt;/i&gt; which are composed of opaque yellowish or yellowish-green tissue (Ref. 1). Moreover all Sepioidea and Myopsida and &lt;i&gt;Ctenopteryx&lt;/i&gt;, a species belonging to the Oegopsida (Ref.2) possess accessory nidamental glands. The most striking property of these glands is their intense coloration varying from yellow to orange and red.  This paper is a comparative study of the accessory nidamental glands...

Maritime boundaries: Canada vs. United States
Provedor de dados: Open Marine Archive
Autores: Cuyvers, L.
When President Harry S. Truman issued a proclamation in 1945 that claimed an exclusive right of the United States to exploit the resources of the seabed and subsoil of its continental shelf, he heralded a new era of national interest in the oceans. The American measure set a policy that was quickly followed by many other states of the world, and as a result, the exclusive jurisdiction of coastal states over the resources in their offshore continental shelves has become one of the generally settled issues of international law of the sea. Less clear, however, are the rules that govern the delineation of the boundaries on the shelf between adjacent and opposite states. Different interpretations of rather ambiguous rules has led to friction between several...

Taxonomic notes on species of &lt;i&gt;Tisbe&lt;/i&gt; (Copepoda, Harpacticoida) from a Belgian sluice dock
Provedor de dados: Open Marine Archive
Autores: Bergmans, M.
&lt;i&gt;Tisbe furcata, T. gracilis, T. holothuriae&lt;/i&gt; and &lt;i&gt;T. battagliai&lt;/i&gt; are reported from the Sluice Dock near Ostend (Flemish Coast). The latter three species are new to the Belgian fauna. A cross-breeding experiment between strains of &lt;i&gt;T. holothuriae&lt;/i&gt; from Ostend and Venice (Italy) conforms perfect interfertility and hybrid F&lt;sub&gt;1&lt;/sub&gt; heterosis. &lt;i&gt;T. furcata&lt;/i&gt;, the "stumbling block" of the genus, is described and an account is presented of the characteristics and ontogeny of its colour pattern.

An inexpensive turbidimeter for the automatic culturing of filter feeders
Provedor de dados: Open Marine Archive
Autores: Versichele, D.; Bossuyt, E.; Sorgeloos, P.
Automatization in the food distribution is necessary for the controlled culturing of filter feeders in high densities. Numerous devices have been described to distribute specific quantities of food suspension at preset time intervals (cf. review in Kinne, 1977). The number of systems which, however, add food whenever a preset critical turbidity of the medium is exceeded are rather limited. They furthermore are either very expensive (sophisticated equipment) or have to be cleaned very often (cf. review in Sorgeloos et al., 1976). We tried to simplify the technological complexity of the existing systems and developed an inexpensive, automatic, self cleaning food distributor. This apparatus measures the turbidity of the culturing medium which is pumped into a...

Production of &lt;i&gt;Nereis diversicolor&lt;/i&gt; O.F. Müller (Polychaeta) in a shallow brackish-water pond
Provedor de dados: Open Marine Archive
Autores: Heip, C.H.R.; Herman, R.
A &lt;i&gt;Nereis diversicolor&lt;/i&gt; population inhabiting a shallow and landlocked brackishwater pond in Belgium has been studied over one year to estimate its production. This population reproduces from May to December with a peak in August. Total numbers vary between 5,000 and 17,000 individuals/m², the total standing stock lies between 13 and 39 g dry weight per m², with a mean of 24 g dry wt m&lt;sup&gt;-2&lt;/sup&gt;. Individuals grow linearly over long periods of time, although slower when they get larger. Production was calculated by determining the weight-specific growth-rate of the different size-classes in the populations; production in the year 1975-1976 was equal to 61 g dry wt m&lt;sup&gt;-2&lt;/sup&gt; year&lt;sup&gt;-1&lt;/sup&gt;.

La glande nidamentaire accessoire de &lt;i&gt;Sepia officinalis&lt;/i&gt; L.: analyses biochimiques des pigments des bactéries symbiotiques
Provedor de dados: Open Marine Archive
Autores: Van den Branden, C.; Richard, A.; Lemaire, J.; Decleir, W.
An electron microscopic study of the accessory nidamental glands from &lt;i&gt;Sepia officinalis&lt;/i&gt; L. shows a secretory cycle in the epithelial cells and the presence of bacteria in the tubules of the gland. A correlation between sexual maturity, the color of the gland and the total number of symbiotic bacteria can be demonstrated. A biochemical study shows that the correlation of the gland is due to several carotenoid pigments. The most important of these is an orange-red xanthophyll that has been called Sepiaxanthine. It is probably formed in the bacteria as a result of the secretory activity of the epithelial glandular cells. This whole mechanism and the role of the bacteria and pigments need further research.

The tetrasporophytes of &lt;i&gt;Polysiphonia banyulensis&lt;/i&gt; Coppejans collected in Corsica correspond exactly to those collected at Banyuls (Pyr.-Or., France), in that these also have 5 pericentral cells. The presence of 4 pericentral cells, mentioned in the original description is only correct for a part of the holotype. Thus &lt;i&gt;P. banyulensis&lt;/i&gt; belongs to the section &lt;i&gt;Polysiphonia&lt;/i&gt;.The female gametophytes, collected in July 1977 at Calvi (Corsica) are smaller and present numerous short-stalked spherical cystocarps without special cells around the ostiole. The other characters of the species (typical aspect of trichoblasts, presence of 5 pericentral cells, total absence of cortication) are also present.

Autores: Marinis,G. de; Delitti,W. B. C.; Ferreira,A. A. A.; Santos,R. F. dos.
Sementes de picão-preto (Bidens pilosa L.) foram germinadas em placas de petri sobre papel de filtro molhado com diferentes concentrações de fluometuron (0, 5, 25, 125 e 625 ppm). O ensaio foi conduzido em condições de laboratório, com variação de temperatura entre 24°C e 28°C e intensidade luminosa máxima de 600 lux e foi encerrado após sete dias (168 horas). O fluometuron diminuiu a germinabilidade e o comprimento da radídula e do hipocótilo, afetou o formato dos cotilédones e, nas concentrações mais elevadas, impediu a rejeição do pericarpo. Os efeitos observados não são atribuíveis a lesões bioquímicas do processo fotossintético.

Foi conduzido um experimento no município paulista de Barra Bonita, com aplicações aéreas, onde foram comparadas as distâncias de deriva apresentadas por bicos de diversos tipos posicionados em ângulos diferentes. As aplicações foram feitas com uma solução de água contendo 0,1% de corante Lissamine Turquesa, com gasto de 30 1/ha. Os resultados mostraram a influência do ângulo formado pelos bicos em sua colocação na barra de pulverização e a influência do diâmetro das gotas de pulverização no efeito da deriva. Os bicos cônicos D8-45 montados com capa &lt; •Raindrop - reduziram significativamente o tamanho das gotas, o mesmo acontecendo com o bico &lt; •Solid Stream, posicionado a 45°.

Um experimento foi conduzido em Campinas, em latossolo vermelho escuro, barrento, por dois anos consecutivos, para testar o efeito dos herbicidas trifluralin, vernolate e alachlor e duas doses de nitrogênio, na nodulação e produção de soja, CV santa rosa, inoculada. No primeiro ano, os herbicidas não influenciaram a nodulação aos 35, 58 e 98 dias após o plantio. A aplicação de nitrogênio diminuiu o peso dos nódulos secos observados aos 58 dias, e seu número e peso, aos 98 dias. A produção de grãos foi semelhante para todos os tratamentos. No segundo ano, a nodulação das plantas inoculadas não foi influenciada pela aplicação de nitrogênio, porém nos tratamentos com nodulação espontânea (não inoculados), o peso dos nó dulos secos diminuiu significativamente,...

O efeito de EPTC (S-etildipropiltiolcarbamato) sobre o desenvolvimento e a absorção de macronutrientes até o florescimento e os seus teores nas sementes e vagens, na colheita, foi estudado em dois experimentos de campo com a cultura do feijão, var. Carioca. O EPTC foi aplicado em pré-plantio com incorporação nas doses de 0, 1, 2, 4, 8 e 16 kg/ha em dois experimentos em solos argiloso e barrento. A avaliação da ação do herbicida sobre o desenvolvimento da cultura se fez pela obtenção de pesos de matéria seca de folhas, caules e vagens, durante o ciclo e número de plantas e produção de sementes na colheita. No início do florescimento foram analisados os teores de N, P, K, Ca, Mg e S em folhas e caules e, na colheita, em vagens e sementes. O EPTC, nas doses...

Período crítico de competição entre comunidades de plantas daninhas e o algodoeiro (Gossypium hirsutum L.) no Estado de Minas Gerais
Provedor de dados: Planta Daninha
Autores: Laca-Buendia,J. P. del C.; Purcino,A. A. C.; Penna,J. C. V.; Ferreira,L.
Foram instalados nove ensaios no período de 1973 a 1976 em solos LVA, LE e LR de três localidades do Triângulo e duas no Norte do Estado de Minas Gerais, Brasil, a fim de se estudar as épocas críticas de competição de plantas daninhas com o algodoeiro (Gossypium hirsutum L.). Os tratamentos foram: capinas até 2, 4, 6, 8 primeiras semanas e durante todo o ciclo; e capinas após 2, 4, 6, 8 primeiras semanas e todo o ciclo sem capinas. Os resultados mostraram que a competição das plantas daninhas, quando não controladas, com a cultura, provocou 90,22% de perda na produção no Triângulo Mineiro e 70,73% no Norte de Minas. Em relação à testemunha, mantida livre de competição durante todo o ciclo, o melhor rendimento foi obtido quando se manteve a cultura livre de...

THE ECONOMICS OF SNOW MANAGEMENT:  AN APPLICATION OF GAME THEORY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Snyder,   John R.; Skold,   Melvin D.; Willis,   Wayne O.
The physical potentials of managing snow to obtain additional soil water for the enhancement of plant growth have been demonstrated. The benefits exceed the costs of snow management when averaged over time. The net benefits in any one year may be positive or negative, however, depending in part upon climatic variables. This paper casts the decision of whether or not to practice snow management as a farmer-against-nature game theory model. If farmers are pessimistic about precipitation prospects, snow management is not a profitable practice. When normal or above normal precipitation is expected, snow management is profitable.

The history of starvation in the world is very tightly linked with the history of humanity.  The problem of starvation was discussed in 1945 at the Worldwide Constitutional Conference of Food and Agriculture Organization of the United Nations.  The main goal of the organization was and remains a food policy for the benefit of all, in order to liberate all people from starvation.   Since 1950, there has been a notable decrease in agricultural production per capita in the developing counties in comparison to the needs.  In 1972 and 1973, poor harvests created a dramatic situation in many regions of the world and once again it was in the developing countries where people suffered the most.  In the Sahel countries, many thousand of lives would have been lost...

NEW ZEALAND BEEF AND SHEEP SUPPLY RELATIONSHIPS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rich,   M.M.
The primary purposes of this study are to measure major relationships describing the responses of different components of sheep and beef farming capital stock in New Zealand to changes in economic conditions, and to investigate the way in which this capital stock has changed over time. These objectives are pursued by attempting to specify an econometric model that recognises joint production between sheep and beef cattle and also takes account of joint firm/household decision making. Aggregate New Zealand data for the period 1952/53 to 1973/74 are fitted to the model using Full Information Maximum Likelihood estimation.

Autores: Leistritz,   F. Larry; Murdock,   Steven H.; Toman,   Norman E.; Hertsgaard,   Thor A.
For rural areas in which large scale industrial and resource development projects are located, the need for timely projections of the magnitude and location of economic, demographic, fiscal and other likely impacts is clearly apparent. The purpose of this paper is to describe a computerized model for projecting the effects of large scale developments on business activity, personal income, employment, population, requirements for selected public and quasi-public services, and public sector costs and revenues and to demonstrate the utility of the model for projecting local area impacts. The structure, data base, and interrelationships of each of the model's six major components are described. Its validity in simulating economic and demographic changes at...

STABILISATION AND RISK REDUCTION IN AUSTRALIAN AGRICULTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Quiggin,   John C.; Anderson,   Jock R.
Agricultural producers typically are faced with risk about the yields they will experience and the prices they will receive. Stabilisation schemes can spread risk and thereby reduce the risk faced by individual producers. The risk-reducing capacity of a scheme and the cost of risk reduction depend upon the design of the scheme. In particular, it is important to distinguish between risk and instability. A classification of scheme designs is presented to bring out the effects of various design types. Schemes for the wheat industry are given most attention.

EFFECTS OF COAL BLENDING ON THE UTILIZATION OF HIGH-SULFUR IOWA COAL AND LOW-SULFUR WESTERN COAL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Miller,   John J.; Drinka,   Thomas P.; O'Riley,   Craig W.; Baumel,   C. Phillip.
Sulfur dioxide emission standards for coal-fired stationary boilers generally range from 1.2 pounds per million Btu of heat input for large boilers constructed after August 17, 1971 to 5 to 6 pounds of SO2 emissions for other large boilers constructed on or before August 17, 1971 and for boilers located in nonrural areas. These standards generally prohibit the use of coal with sulfur contents &gt; 0.6 percent for new large boilers and &gt; 2.5 to 3.0 percent in other boilers. Low-sulfur western coal shipped in unit-trains and mechanically blended with higher-sulfur coals located close to the boilers provides a method of increasing the production of the high-sulfur Iowa coal as well as the consumption of low-sulfur western coal and, at the same time, of...

SYSTEMS ANALYSIS OF LIVESTOCK WASTE MANAGEMENT:  A STUDY OF LARGE-SCALE DAIRYING
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Matulich,   Scott C.; Carman,   Hoy F.; Carter,   Harold O.
The analytical approach to studying waste management is investigated here in the context of large scale dairying. The typical short-run approach that regards waste management as separable from primary production is contrasted with a longer-run systems approach in which waste management is regarded as an interdependent stage of production. Failure to consider interdependencies between waste management and agricultural production could compromise potential efficiencies in the overall system. Furthermore, cooperative waste treatment and disposal among livestock producers may contribute to greater efficiency and afford opportunities for resource conservation and recovery through waste utilization.

FACTORS AFFECTING DEMAND AND SUPPLY OF RICE IN SIERRA LEONE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kargbo,   Alimami M.
Sierra Leone, like most developing  countries is primarily agricultural, with about 75 percent of its population getting its living from farming.  The main characteristic of its farming is the large number of small holdings-averaging about two hectares per farm.  Most of these farms are fragmented.  Large-scale farming is a fairly recent development and the few large farms are either government or quasi-government institutions, confined to crops that require expensive machinery and timely processing.  In the country's search for new sources of economic expansion, agriculture assumed first priority.  This was due, in part, to the fact that a large percentage of the population derived its living from agriculture.  In addition, the development of agriculture...

A REVIEW OF TECHNICAL EVIDENCE ON THE USE OF ANIMAL TRACTION IN SAHELIAN FARMING SYSTEMS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bloom,   Roger A.
The use of animal traction as a source of on-farm power has often been regarded as a logical and appropriate approach for improving Sahelian agriculture.  Animal power, it is argued, enables the farmer to execute timelier agricultural operations and to overcome the seasonal labor constraints which inhibit agricultural production.  Furthermore, by increasing total production and returns to farm labor animal traction makes possible the attainment of food self-sufficiency and an increased marketable surplus.  There has been a relatively long history of attempts to introduce animal traction in the Sahel, but in spite of the proposed theoretical benefits resulting from its use, the many efforts of integrating animal traction into the traditional farming systems...

Autores: Stevens,   Thomas H.; Blake,   Martin J.; Williams,   Lawrence G.
This paper demonstrates the differences that result from estimating coal demand functions using highly aggregated regional data rather than less aggregated state data. At first glance the coal demand functions based on regional data appear to explain well and seem useful in policy making. However, coal demand functions based on state data show differences in the demand structure in each state of the region. Policy decisions that may seem appropriate based on aggregated regional data may have much different impacts on individual states in the region.

This paper focuses on some emerging and recurring issues of wool promotion policy. In particular it examines the implications for wool promotion of recent developments in raw wool marketing policy. The issues analysed are the relationship between International Wool Secretariat (IWS) promotion and wool stockpiles held by statutory authorities, market development for wool, the integration of IWS activities with those of statutory wool marketing authorities and the future organisation and control of IWS.  These issues are real and significant ones even if largely unsuspected by the majority of woolgrowers. Indeed, unless they are satisfactorily resolved, serious strains could arise within the partnership that forms the IWS. The eventual outcome could be the...

IMPLICATIONS OF THE TAX REFORM ACT OF 1976 FOR FARM ESTATE PLANNING
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Roush,   Clint E.; Mapp,   Harry P., Jr.; Maynard,   Cecil D.
An intergeneration transfer simulation model is used to project estate transfer costs and the value of transfers to the heirs before and after the tax reform act of 1976. Lower Federal estate taxes result for estates that qualify for the special use valuation of farmland provision of the new law. Replacing the $60,000 estate exemption with the $47,000 estate tax credit and revising the tax rate schedule increases Federal estate taxes when the taxable estate is between $1.175 million and $9.353 million. The new carryover basis rules for estate assets acquired from decedents dying after 1979 also increase transfer costs.

A COMPARISON OF ALTERNATIVE PROCEDURES FOR CALCULATING THE RATE OF RETURN TO AGRICULTURAL RESEARCH USING THE PRODUCTION FUNCTION APPROACH
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Davis,   Jeffrey S.
The aim of this paper is to test whether the marginal internal rate of return (MIRR) to research and extension estimates are sensitive to the estimation procedure used to find them. To achieve this, a summary of the previously used estimation procedures is made. Following this a cross section aggregate production function estimate is developed for the U.S. in 1964. The parameter estimates from this model are used to calculate the MIRR's using the different estimation procedures.

A METHODOLOGICAL BASIS FOR THE EVALUATION OF MARKETING LOSSES OF FOODS IN DEVELOPING COUNTRIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Silva,   Carlos Arthur Barbosa da.
The shortage of food for a substantial proportion of the world's population is a problem which has been challenging our society for a long time.  In the 1972-1974 period an estimated 1.3 billion people subsisted in less developed countries with dietary energy supplies under the minimum nutritional requirements, and the current outlook is for a widening gap between needs and food supplies.  Although progress has been made in production oriented research, such as the development of high yielding crop varieties and of better way to control pests and diseases, there is still a need for additional means to increase the world food supply.  The objectives of this paper are as follows: 1) to define the problems and its relevance for developing countries; 2) to...

Farmer Income and Expenditure Patterns in a Wheat-Sheep Region
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Davis,   D.C.; Mullen,   John D.; Bryant,   M.J.
Information on farm incomes and expenditure patterns for the eight year period 1968-69 to 1975-76 was collected in a survey of 102 farm businesses. Average gross farm earnings varied by up to $20,000 over the period, with marked variations in individual enterprise earnings also being observed. Spending on farm current costs, investment and livestock and consumption closely followed the trends in incomes. A summary of the data collected for 90 of the 102 farm businesses is presented.

ECONOMIC AND SOCIO-ENVIRONMENTAL EVALUATION OF PREDATOR CONTROL ALTERNATIVES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gum,   Russell L.; Martin,   William E.
A simulation model containing both economic (monetary) and socio-environmental (value index) components is developed in a case study of predator control alternatives. Particular emphasis is given to the description and justification of the socio-economic model. The economic model is estimated in terms of producers’ and consumers’ surpluses. The empirical tradeoff function developed suggests that alternatives to recent predator control programs exist that could be “better” for both general public and producer interests. The general approach can serve as a prototype for policy evaluations involving multiple objectives.

AN ANALYSIS OF CONSTRAINTS ON EXPANDING RICE OUTPUT IN THE CASAMANCE REGION OF SENEGAL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rigoulot,   Jean Pierre.
Senegal imports about 200,000 tons of rice annually.  These import consume a large share of the national budget and represent a heavy outflow of foreign exchange.  Despite the implementation of various agricultural projects aimed at increasing domestic rice production, Senegal still relies on imports to fill its deficit and there is no evidence that the situation will change in the near future. The purpose of this paper is to identify and analyze selected factors which are believed to impede expansion of rice production in the Casamance (southern) region of Senegal.  The following factors are studied:  1)  climatic uncertainties (effects of the drought); 2)  the competition between groundnuts and rice for the allocation of family labor; 3)  the...

AN EVALUATION OF ECONOMETRIC MODELS OF U.S. FARMLAND PRICES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Pope,   Rulon D.; Kramer,   Randall A.; Green,   Richard D.; Gardner,   B. Delworth.
Previously published empirical models of U.S. farmland prices are reviewed and reestimated including recent data. It is apparent that structural changes have occurred. A simple single equation econometric model with less economic structure appears to forecast better than a simultaneous equation model. Finally, Box-Jenkins forecasts are roughly as good as those based upon a simultaneous equation econometric model, but somewhat inferior to the single equation model. The results suggest that further research may be needed to explain recent movements of farmland prices.

AN ANALYSIS OF RICE SUPPLY AND DEMAND IN THE IVORY COAST
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Coulibaly,   Dramane.
Despite the importance of rice in Ivorians's diet, and thus in the economy of the Ivory Coast, self-sufficiency in rice production, until recently, has received little attention from economists and statisticians.  Agronomists, sociologists and anthropologists have examined in some detail the cultural practices, soils, land barriers, tools and basic techniques used by the Ivorian farmers.  But they have failed to produce much needed basic information related to crop acreage, yields, prices and other areas which are most relevant for policy formulation.  This paper analyzes the rice demand and supply in the Ivory Coast, and attempts to estimate both price and income elasticities of demand, and price elasticity of supply.

Comparing the Box-Jenkins and Econometric Techniques for Forecasting Beef Prices
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Bourke,   I.J.
Most published studies which consider the forecasting of agricultural prices have utilised the econometric technique. In many non-agricultural forecasting situations, the Box-Jenkins technique has been found to be of equal accuracy. This paper compares the forecasting accuracy of the Box-Jenkins and econometric techniques for forecasting manufacturing-grade beef prices in the United States of America, and suggests that the Box-Jenkins technique may be the more accurate.

Foodgrain Supply, Distribution, and Consumption Policies within a Duel Pricing Mechanism: a Case Study of Bangladesh
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ahmed,   Raisuddin.
Conflict between the short run welfare of poor consumers and agricultural production incentives creates some of the most difficult policy issues facing developing countries. Resulting policy option constraints are particularly severe in very low income countries. The conflict may on the one hand impede the growth in al production essential to improve long term welfare of low income consumers, and on the other hand restrain policies to increase consumption, which in the long run is essential to the success of the measures taken to increase production. The widely observed phenomenon of urban bias in food price policy is itself a product of the nature of low income societies and of this complex conflict.  This research by Raisuddin Ahmed delineates and...

THE SHORT-TERM EFFECT OF DOMESTIC OIL PRICE INCREASES ON THE AUSTRALIAN ECONOMY WITH SPECIAL REFERENCE TO THE AGRICULTURAL SECTOR
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Vincent,   David P.; Dixon,   Peter B.; Parmenter,   B.R.; Sams,   D.C.
The rise in the domestic price of oil products implied by the new import parity pricing policy for domestic crude oil is likely to pose some problems for macroeconomic management. In this paper an attempt has been made to quantify the short-run adjustment problems involved, using the ORANI 78 model of the Australian economy. Results are presented for a range of variables of interest, including macroeconomic variables, industrial and workforce composition and farm incomes. With fixed real wages, farm incomes are projected to decline by between 6 and 8 per cent.

AN ECONOMETRIC EVALUATION OF STABILIZATION POLICIES FOR THE U.S. GRAIN MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Arzac,   Enrique R.
This paper evaluates stabilization policies by applying methods of stochastic control and dynamic analysis to an econometric model of the U.S. grain market. Its main results are: (1) the aggregate consumer and producer surplus generated by the model is insensitive to the choice of the market regime; (2) policies directed to stabilize prices at levels compatible with nondecreasing farm revenue require the management of both grain inventories and domestic supply; (3) price fluctuations are significantly less under optimal stabilization than in the unregulated version of the model; and (4) historical policies have destabilizing effects on the market model.

Two investigations are reported. The first is a comparison of average prices for two cattle types within pairs of some major auction centres in Australia. Significant price differences existed in three of the four cases studied. The second is a study of the main determinants of price differences between auction selling centres through a case study of a large and small auction centre. The major factor explaining the price differences between the two auction centres was lot size. This factor also influenced price variation within auctions. The number of buyers purchasing cattle did not affect price levels.

Autores: Welsch,   Delane E.; Stuthman,   Deon; Showman,   Alan.
A mail survey was conducted in 1977 of farmers who were thought to be oats producers, using names obtained from several lists. The purpose of the 1977 mail survey was to obtain answers to the following questions: (1) What kind of farmer grows oats, (2) Where does he grow them, (3)Why does he grow them, (4) How does he produce them? Answers to these questions should enable the breeding program and the Extension Program at the University of Minnesota to better address the problems of oat production and thus maintain, or hopefully improve the relative competitive ability of oats as a crop in Minnesota.

"Market alternatives for Carp, Alewife and Sucker from the Michigan Great Lakes" is a study of the potential economic value of three species of fish existing in large supply in the great lakes.  The study focuses on the feasability of potential uses of carp, sucker, and alewife as a food source and as a protein source for industrial meal, oil and solubles.  The potential demand for these species as a marketable food fish was analyzed using the theory of consumer demand.  Tuna, sardines, cod, perch, and salmon products were selected to study the affect of changes in price and income on demand. Conclusion from this analysis were used to specify an ordinary least squares equation of demand for canned and processed tuna, sardines, cod, perch, and salmon...

FUNCTIONAL FORM SPECIFICATION IN THE QUARTERLY DEMAND FOR RED MEATS IN CANADA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kulshreshtha,   Surendra N.
Most demand studies, particularly those for food products, choose somewhat arbitrarily either a linear or a log-linear functional form. Since choice of functional form has implications for elasticities and their properties over time, either form may be considered restrictive. An empirical test of functional form in the short-run (quarterly) demand for four red meats is presented in this paper. For beef demand, neither a linear nor a log-linear form is appropriate. Similarly for pork and lamb demand, a linear functional form is not appropriate, but the log-linear one is. For veal demand, although data supported both function forms, a linear form is preferred when seasonal influences are accounted for.

THE LABOUR RESPONSE OF QUASI-SUBSISTENT VILLAGE CRAFTSMEN IN RURAL PAPUA NEW GUINEA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Philp,   Norman E.
In this study of labour-leisure choice, a labour supply equation is derived from a Stone-Geary utility function and extended to incorporate several 'non-economic' variables. Such variables are made functions of the 'minimum subsistence' quantities which characterise the standard Stone-Geary model. The model is then estimated on cross-sectional data obtained from a field survey of quasi-subsistent piece rate producer-consumers living and working in a number of New Guinean villages. Approximately two-thirds of the observed variation in the weekly work commitment of the sampled workers was explained by the model. The response of cash work commitment to variation in earning rates was found, on average, to be highly inelastic and slightly negative in direction....

USE OF EXTRANEOUS INFORMATION WITH AN ECONOMETRIC MODEL TO EVALUATE IMPACTS OF PESTICIDE WITHDRAWALS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Taylor,   C. Robert; Lacewell,   Ronald D.; Talpaz,   Hovav.
A framework for combining extraneous information with an econometric model to evaluate the economic impacts of pesticide withdrawals is presented in this paper. The extraneous information, which can be a best guess or experimental data, is used to shift an econometrically estimated supply function. The full sectoral econometric model is then simulated through time with and without the supply shift to estimate the relative impacts of withdrawing the pesticide. The theoretical framework is applied to the withdrawal of all insecticides used on cotton.

SOCIO-ECONOMIC STUDY OF THREE VILLAGES IN BAUCHI STATE, NIGERIA (WITH EMPHASIS ON LABOR UTILIZATION)
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ingawa,   Salisu Ahmed.
Although agriculture no longer serves as the leading contributor to Nigeria's Gross National Product (GNP) and leading foreign exchange earner, it still is the leading employment sector of the vast majority of Nigerian population.  The decline in importance of the agricultural sector in terms of GNP has been partly due to the phenomenal growth in the petroleum sector of the economy.  Other factors of relevance to this decline include a long period of adverse weather conditions, negative overall terms of trade in relation to other sectors of the economy as well as a very disturbing rate of farm urban migration.   The objectives of this paper stem from the realization that in order to solve the problems plaguing small farmer agriculture, as in the study...

CASSAVA SUPPLY RESPONSE IN MINAS GERAIS STATE, BRAZIL:  AN EMPIRICAL EVALUATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Rodrigues,   Lecio Maria.
When the Portuguese and Spanish navigators landed on the American continent in the 15th century, they found cassava being grown by Indians and used to prepare food and alcoholic drinks.  For this reason, cassava can be considered a native American plant which has spread to other regions of the tropics.  Cassava refers to any of several plants which are grown widely in many areas of the tropics for their fresh, starchy, edible root stocks.  It is known as cassava in English speaking regions, as manioc in French speaking areas, as tapioca in English speaking parts of Southeast Asia, as mandioca in Brazil, and as yuca in Spanish speaking regions of South America.  As one of the largest countries in the world, and with the necessity for much greater emphasis...

A COMPARISON OF DEPRECIATION METHODS UNDER CURRENT COST ACCOUNTING
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Davey,   L.E.
In New Zealand the Richardson Report has recommended to government the adoption of a form of inflation accounting known as Current Cost Accounting (CCA). This paper reports research carried out to determine which of the traditional historical cost depreciation methods used in farm accounting might be most appropriate when adapted to a current cost basis. The current cost depreciation methods are compared on the basis of their ability to predict accurately actual replacement values for a survey sample of farm tractors and headers. The resultant measures of depreciation are compared with those currently allowable under New Zealand taxation laws, and the proposition that investment allowances on purchases of new machinery offset the inadequacies of historical...

QUARTERLY ECONOMETRIC MODEL AND FORECASTS OF THE MINNESOTA AND U.S. IRON MINING INDUSTRY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lyche,   Harald C.; Maki,   Wilbur R.
The Report projects quarterly production and stock levels for the Minnesota and U.S. iron mining industry to the year 2000. Projections of Minnesota's iron industry employment are subsequently derived from the production forecasts. Ordinary least squares regression techniques are used to analyze the seasonality patterns that existed between 1955 and 1978. The regression equations, based on the quarterly data, were calibrated so they could be used to seasonalize the annual iron ore consumption, production and import projections developed by the U.S. Bureau of Mines. Alternate industry forecast series are presented to facilitate comparison with the yearly baseline projection series.

DISAGGREGATED ANALYSIS OF SHORT-RUN BEEF SUPPLY RESPONSE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ospina,   Enrique; Shumway,   C. Richard.
Conceptual problems in model specification of beef supply response studies are investigated and a simultaneous equation model is formulated to estimate annual U.S. carcass supply, demand, and inventories of beef. Three basic issues are addressed: (a) disaggregation, (b) simultaneity, and (c) differentiation between current and expected price effects. Empirical results indicate positive supply response of each quality type of steers and heifers, and negative supply response of cows to current own-price changes. The derived aggregate supply elasticity is positive. The effects of grain price changes on beef price, supply and composition are also evaluated.

THE USE OF A DECISION MAKER'S UTILITY FUNCTION IN A LINEAR PROGRAMMING ANALYSIS OF AGRICULTURAL POLICY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Parton,   Kevin A.
A decision theoretic approach to agricultural policy decision making is examined to discover whether a utility function of an Australian Wool Corporation decision maker can be established and, if so, whether this can be used to improve the policy analysing performance of an agricultural sector linear programming model. After discussing the theoretical requirements of the utility function elicitation and the elicitation procedures, the characteristics of the resulting functions are examined. A means for its inclusion in a linear programming framework is described and some analysis of policy is carried out. The general conclusions are that the relevance of the agricultural sector analysis is enhanced by the use of such a utility function.

DYNAMICS OF FOOD PRICE INFLATION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lamm,   R. McFall  Jr.
A supply-shift concept of food price inflation is offered as an explanation of why food prices have increased in recent years. This view is consistent with cost-push theories of inflation. The effects of higher farm product prices on food prices are analyzed using Pascal distributed lag models of the price adjustment process. Estimates are presented for 23 selected food products. The results indicate that higher farm prices are passed through to the retail level most quickly for food products which are not highly processed.

AGRICULTURAL CREDIT IN COSTA RICA:  DIAGNOSIS AND RECOMMENDATIONS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Barquero,   Gerardo.
Although credit can be directed with sufficient facility toward some economic activities, the same cannot be said about agriculture, first because there are thousands of clients and secondly, most of them do not meet the requirements for obtaining a loan.  Moreover, they do not know how to utilize credit and frequently they do not accept the general conditions that the credit institutions establish.  Unfamiliarity with the sources of funds is another problem.  Therefore, if credit does not accompany other complementary services, like technical assistance for example, the farmers present low modernization indexes, and productivity levels are not very different in relation to those who do not use credit.  Given the importance that agricultural credit has for...

FARM TRANSFERS IN SWITZERLAND:  WITH A SPECIAL EMPHASIS UPON FARM APPRAISALS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gantner,   Urs.
In Switzerland it is common for the farm businesses to be transferred within the family because the law provides that the heir can purchase the business at its investment value.  The investment value is arrived at by an income capitalization approach.  The investment values of farm businesses are well below corresponding market values.  The purpose of these regulations is to avoid the division of the land among the heirs and excessive debts for the young farm family.  The purpose of this paper is to discuss the transfer of farms, to explain the present method of appraising farms, to evaluate a number of alternative methods of farm appraisal, and to make some new proposals within the given legal framework.  The transfer of farms involves issues such as the...

Interpretation of Cost-Price Ratios
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jackson,   Brenda.
The usefulness of movement in costs and prices (sometimes termed the "cost-price squeeze") has been challenged by a number of authors. Despite this, a theme which remains common to some recent articles is that a decline in the ratio of prices received to prices paid denotes a situation which must be overcome. A simple model is used to demonstrate why movements in aggregate costs and prices tell us very little about the state of the agricultural sector and, in particular, about farm income. Results of the model are examined in conjunction with actual movements in selected agricultural indicators over the past twenty-five years.

PRICING EFFICIENCY IN THE RETAIL MEAT MARKET
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Naughtin,   John C.; Quilkey,   John J.
The degree of pricing efficiency achieved in the retail meat market is reconsidered in this paper. The approach adopted is to develop an economic model of the pricing behaviour of retail butchers, to postulate a behavioural model consistent with the economic model, and to test this model using the data supplied by three retail butchers. The results indicate that the deleterious effects of price levelling and averaging practices on pricing efficiency may have been understated in earlier studies. It is concluded that further research is required to re-assess the extent of the problem of pricing efficiency in the retail meat market.

Forecasting N.S.W. Beef Production: An Evaluation of Alternative Techniques
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gellatly,   Colin.
This paper reports on the evaluation of the performance of several forecasting methods used to forecast New South Wales quarterly beef production, one quarter ahead. The forecasting procedures used are a single equation regression model, a Box-Jenkins univariate time series model, a forecasting committee's judgement and a naive model. Absolute accuracy and relative accuracy measures are used to evaluate ex ante forecasts. Although the evaluation gave some mixed results according to the criteria used, it appears that the forecasting committee performed better than the alternative forecasting procedures considered in this study. However, the results indicate that the committee's performance was not much better than that of a naive (no change) model,...

The paper reports a study of the operation of the breeding system in the milk herd in Israel. Basic notions in quantitative genetics are explained and incorporated in a simulation model which is used to illustrate and analyse the selection process. Particularly emphasised are the traits common to selection and other research and development effort; among them, search, limited information, and biological and technical constraints. Differential technical changes affected the structure of the milk producing industry and its measured productivity; these effects are discussed in the last part of the paper.

ON-FARM PHEASANT ENHANCEMENT POTENTIALS IN IRRIGATED AGRICULTURE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Matulich,   Scott C.; Bagwell,   George.
The transformation of irrigated agriculture into a capital intensive industry has eroded much of the incidental biological complementarities between wildlife and irrigation development. Wildlife management agencies need to assess the economic impact of enhancement programs upon commercial agriculture. In this paper, opportunity costs of on-farm pheasant enhancement practices are estimated for typical Columbia Basin irrigated farms. These estimates are then compared with two measures of net benefits to established the potential feasibility of on-farm pheasant enhancement programs.

The Identification and Measurement of Factors in the Adjustment of New South Wales Farmers to Non-Farm Occupations
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Paul,   Phillip B.
To date, there have been a paucity of studies in Australia which have studied the adjustment of farmers to non-farm situations. A number of relevant overseas studies have been far from complete in that they have failed to identify adequately both the factors contributing to the success or failure of the adjustment process and the type of farmer who is most likely to be most adaptable to the change. This paper attempts to shed some light in this area by identifying significant factors in the adjustment process. It then attempts to discover the type of migrant who is most likely to be adaptable to the re-adjustment process by investigating the relationship between the characteristics of the former farmers and their farm situation prior to migration and their...

EFFECTS OF ENERGY DEVELOPMENT IN THE UPPER COLORADO BASIN ON IRRIGATED AGRICULTURE AND SALINITY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Narayanan,   Rangesan; Padungchai,   Sumol.
A mathematical programming model is formulated to determine the salinity impacts of energy development in the Upper Colorado River Basin. Using this model, the costs and benefits to Upper and Lower Basins in complying with the 1974 EPA regulations on numerical salinity standards are examined.  Optimal water quality levels consistent with economic criteria are established for projected energy growth in the basin. The efficiency costs and equity implications of the salinity regulations are analyzed.

ASSESSMENT OF THE ECONOMIC AND SOCIAL IMPACTS OF AGRICULTURAL TECHNOLOGY:  A CASE STUDY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hussen,   Ahmed M.
Over the years, several have assessed the impacts of changes in agricultural technology. In most studies, the emphasis has been on evaluating the economic impacts of technology. In most studies, the emphasis has been on evaluating the economic impacts of technological change with little consideration of the secondary and tertiary distributional impacts of such change. This article uses partial equilibrium analysis to estimate the gross and net social rates of return arising from proposed mechanization of strawberry harvesting in Oregon. The discussion considers other factors not explicitly accounted for in the economic model, (e.g., social and technical) but which are likely to have repercussions on the estimated social rates of return.

Impacts of Climatic Variability in Australian Agriculture: A Review
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Anderson,   Jock R.
A framework is sketched for exploring the pervasive impacts of variations in climate on the uncertainties and instabilities of the Australian rural sector. Low rainfall is identified as the dominating climatic variable. Effects of climatic variation are investigated and measured at farm, regional, industrial, sectoral and national levels. Where possible, sensitivities to climate are measured by elasticities of production with respect to rainfall indexes. Some consequences of possible climatic change are discussed.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Jones,   John M.
In recent years there has been a growing interest in the development of methodologies related to the formulation and appraisal of projects.  This is reflected in an increasing number of scientific papers and courses offered at different levels on the subject, most of which are directed for application in less developed countries.  A wide variety of institutions are contributing in different ways to this development.  Resulting from this interest, several operational procedures have been suggested which enable the analyst to perform financial as well as social appraisal of projects, where financial refers specifically to appraisal for the private and/or public participants in the project, and social refers to analysis from the perspective of economy-wide...

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wieland,   James S.; Leistritz,   F. Larry; Murdock,   Steven H.
The socioeconomic characteristics of construction and operating work forces at energy related facilities in the Northern Great Plains were analyzed. A primary interest was to explain differences in local hire rates and settlement patterns on the basis of characteristics of the project and site area. In general, it was found that local hire rates for operating workers can be expected to be substantially greater than for construction workers when differences in project and site characteristics are taken into account. Nonlocal construction workers were found to live in larger communities and to commute substantially greater distances to the project site than nonlocal operating workers.

Brazil’s Minimum Price Policy and the Agricultural Sector of Northeast Brazil
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fox,   Roger W.
The effect pubic policy has on the relative prices of agricultural commodities is a controversial topic in developing countries, developed countries, and international agencies alike. The controversy arises as a result of a lack of understanding of the conflicting effects of relative price changes on various producer and consumer income classes and, when the effects are understood, as a result of emphasizing the value class over another. Unfortunately, there are a few case studies available on the workings of the many and varied approaches taken to agricultural price policy in the developing countries. IFPRI was delighted to take advantage of Roger Fox’s availability to make this study of the minimum price program of Brazil, as it applies to the...

EXPLAINING VARIATIONS IN SHARE CONTRACTS: LAND QUALITY, POPULATION PRESSURE AND TECHNOLOGICAL CHANGE
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: James,   William E.; Roumasset,   James A.
Substantial variations in landowner's share under sharecropping arrangements are documented. Partial relationships between landowner's share and land quality and between landowner's share and physiological population density are explained by extensions of the competitive theory of share tenancy. It is shown that high landowner's share can be expected to be associated with high land quality and or high physiological density. The tendency for increases in population to be associated with increases in landlords' shares can be ameliorated by land-saving technological change.

THE DEMAND FOR MEAT - AN EXAMPLE OF AN INCOMPLETE COMMODITY DEMAND SYSTEM
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Fisher,   Brian S.
Equations describing the demand for beef and veal, mutton, lamb, pork and chicken are estimated using the full information maximum likelihood estimator. Elasticity estimates are presented and the double logarithmic model is compared with a demand system which is derived from the indirect translog utility function. Estimates of the direct price and income elasticities are not particularly sensitive to model specification but the estimated cross-price elasticities are sensitive to the choice of functional form. The results indicate that the double logarithmic specification may be less satisfactory than the alternative presented in cases where restrictions on the parameters are imposed during estimation.

This paper considers the implications of different geographical population definitions in analysis of demand for wildlife recreation. Demand functions for fishing, small game hunting, big game hunting, and wildlife enjoyment are estimated for individual Southeastern states and also for a pooled sample of all the states.  Statistically significant differences between the state and regional estimates of the variable cost coefficient exist in 18 of the 40 cases. Consumer surplus values derived from state cost coefficients can differ greatly from values derived from pooled coefficients.

SOME GENERAL EQUILIBRIUM EFFECTS OF MINING GROWTH ON THE ECONOMY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Stoeckel,   Andrew B.
The effects of mining sector growth are analysed with a five-sector general equilibrium model. The effect of the mineral discoveries is to cause the agricultural sector to contract, but to cause the import-competing sector to expand by a small amount--a result which differs from Gregory's (1976) analysis. However, a mining boom caused by increases in external demand, rather than by new discoveries, leads to a different set of results. Some likely effects of the boom on the growth rates of the different sectors in the economy are reported. Finally, the effects of an export tax on minerals are considered.

On the Development and Use of Automated Management Aids
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Nuthall,   Peter L.
The last twenty years have seen the development of many techniques designed to provide management information. Despite this, comparative budgeting is still the most commonly used analytical technique in applied farm management. There are moves, however, to change this situation through the development of systems designed to enable management aids to be readily available. These systems usually rely on the use of a computer. In this paper the current situation is reviewed by outlining system categories that have been developed and through discussing the important questions in the successful development and use of automated management aids designed for farmer use.

This paper reports on the development of autoregressive-integrated-moving-average (ARIMA) forecasting models for selected cattle price series and the nearby live cattle futures price.  The ARIMA models are fitted to weekly data by employing the Box-Jenkins time series modeling procedure. Relatively accurate short-run forecasts are obtained with the estimated models, with the Midwest price models performing better than Northwest price models, and the nearby futures model being considerably more accurate for longer forecasting horizons.

An index was developed to rank U.S. metropolitan areas according to overall similarities in their socio-economic characteristics to the U.S. average. This index is given as a solution to matching a representative city or market area to a target market as well as matching a group of cities which are similar to each other. The index shows stability in ranking these cities with different consumption data for similar products and proves to be a promising approach whenever the researcher must find a group of cities which are similar to each other and to the target market.

Major emphasis was placed on exploring two related topics.  First, what can U.S. universities do to improve the training of future agricultural economists from LDC's for work in the agricultural development of their countries; and second, what can be done to increase the participation and contribution of young U.S. professionals trained to work in the economics of agricultural development in LDC's.  It is generally recognized that it is desirable for LDC professionals to staff and direct their own programs to develop their agricultural sectors.  This...

PROJECTED USE OF GROUNDWATER FOR IRRIGATION IN THE TEXAS HIGH PLAINS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Young,   Kenneth B.; Coomer,   Jerry M.
Projections of groundwater irrigation under alternative price conditions are computed for representative resource situations in the Texas High Plains. The rate of groundwater depletion and pumping costs are related to the level of irrigation pumpage over the period 1976-2026. The projected economic life of irrigation in this region is responsive to changing economic conditions; in particular, the rate of increase in energy prices for pumping.

ESTIMATION OF WHEAT ACREAGE RESPONSE FUNCTIONS FOR THE NORTHWEST
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Winter,   John R.; Whittaker,   James K.
Acreage response functions for wheat are fitted to aggregate data and pooled time-series and cross-sectional data for the Northwest. It was hypothesized that the pooled data approach provides a useful alternative to using aggregate data since it requires fewer timer-series observations for reliable parameter estimation and it does not require the assumption of constant acreage response elasticities throughout the region. The results of this study verify this hypothesis as well as indicate that regional response elasticities for Northwest wheat acreage may differ greatly from national estimates.

MANAGEMENT EFFECTS OF SPATIALLY DISPERSED LAND TRACTS:  A SIMULATION ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Buller,   Orlan H.; Bruning,   Gary.
A sequential simulation model is used to test a way to study the relationship between net farm income and land tract dispersion, total acres, machinery size and rainfall. The model simulates the day-to-day sequence of field work on a hypothetical farm simulation varying crop acreage, machinery size and for a wet and dry rainfall situation. Data generated by this model are then analyzed using a regression equation estimating the influence of studied variables on net farm income.

A MATRIX OF DEMAND ELASTICITIES FOR FRESH FRUIT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Price,   David W.; Mittelhammer,   Ronald C.
A matrix of direct, cross and income demand elasticities at farm level for 14 fresh fruits was estimated using the mixed estimation technique. Prior estimates were derived from past research and application of the symmetry relation, cross induction and subjective judgment. There were no statistically significant conflicts between the sample and prior information. Even though estimation efficiency increased with the mixed technique, only a limited number of cross elasticities could be estimated.

Autores: Dahl,   Dale C.
The law of judicial remedies deals with the nature and scope of relief afforded a plaintiff following appropriate court procedures and after establishment of a substantive right. These remedies usually fall in one of four categories: (1) damages, (2) restitution, (3) coercion and (4) declaration. This presentation will deal principally with the damages remedy, but a few thoughts regarding the use of a restitutionary remedy are introduced toward the end of these remarks.

ECONOMIC CONSIDERATION IN THE ADOPTION AND DIFFUSION OF FOOD LOSS REDUCTION INNOVATIONS IN THE MARKETING PROCESSES IN DEVELOPING COUNTRIES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Tolmos,   Hugo C. Alvarez.
It is universally recognized that there is a need for increasing the amount of food available for human consumption, and at the same time, for improving the mechanisms of distribution, with views towards making it possible for people to gain access to that food.  Some people have manifested doubts about the possibility of adequately feeding the total human population, given the present trend in population growth and the state of the arts.  Others, the majority, believe that solutions exist but, however, readjustments in the traditional programs are required.  The previous attitude of confidence about the feasibility of achieving targeted goals in population growth and food production, one the implementation of well known solutions were possible, has...

OPTIMAL BUFFER STOCK POLICIES FOR WHEAT AT THE WORLD LEVEL
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kennedy,   John O.S.
Alternative wheat storage policies which maximise the expected present value of returns for consumers, producers, a monopoly storage agency and society as a whole are derived using a dynamic programming model. Results are compared with those from an earlier simulation model, and are found to justify higher investment in storage capacity compared with that suggested by the simulation model. The model is extended to derive optimal storage policies if production follows a stochastic cobweb process.

A Dynamic Programming Model for On-Farm Decision Making in a Drought
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Toft,   H.I.; O'Hanlon,   P.W.
The model, which is based on dynamic programming, enables identification of the sequence of actions in a drought which will lead to the minimum expected cost subject to constraints. The model has been prepared as a tool which may be used to assist graziers to make decisions in a drought. The constraints consist of an upper limit on the number of a particular type of livestock which may be agisted (or droved) in a drought, an upper limit on the number sold and an upper limit on cash outlay. Actions assumed available to the grazier are sale of livestock, agistment (or droving), and supplementary feeding (or allowing mortality).

ANALYSIS OF THE DEMAND AND SUPPLY FUNCTION OF WHEAT IN SAUDI ARABIA PROJECTION OF SUPPLY AND CONSUMPTION THROUGH 1985
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Khalid,   Al-Hamoudi.
With the recent rapid increase in urbanization, wealth, and foreign technicians and labor in Saudi Arabia, wheat is becoming an important diet staple.  A sufficient wheat supply and stabilization of its price are vital to the society.  Yet because of industrial development and economic growth, the total area used for wheat production in Saudi Arabia dropped from 125,000 hectares in 1972 to 45,000 hectares in 1973.  Consequently, the Kingdom has become increasingly dependent on imported wheat.  The objectives of this study are to:  1)  select appropriate variables to establish an estimated supply equation; 2) select appropriate variables to establish an estimated demand equation and 3) apply these two estimated equations to make demand and supply projections.

Attributes Distinguishing Wool Production Enterprises Selling Wool Privately
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: McMahon,   Pat J.; Metcalfe,   John S.
The focus in this paper is to identify characteristics which distinguish enterprises of operators who sold wool privately from those who sold at auction. The "t" tests on differences in means revealed that private sales tend to be associated with small woolproducing enterprises. In Western Australia, the further removed enterprises are from an auction selling centre the lower the probability of a private sale. In the Eastern States, the probability of a private sale was higher during the period of supply management in 1974-75, the average level of indebtedness to pastoral companies was lower for those enterprises from which wool was sold privately and traditional ties to wool selling brokers were apparently important in the 1974-75 wool selling season,...

THE DEMAND FOR NITROGEN, PHOSPHOROUS AND POTASH FERTILIZER NUTRIENTS IN THE WESTERN UNITED STATES
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Carman,   Hoy F.
An economic model of the demand for fertilizer is specified and equations for nitrogen, phosphorous and potash are estimated for individual states in the western United States. The results are acceptable from both an economic and statistical viewpoint. The estimated price elasticity of demand demonstrates considerable variation between states and nutrients. The quantity of each nutrient sold per acre has increased with expected crop price increases and land price increases. In general, the sales response to shifts in the crop production function has been very elastic. Future shifts in fertilizer demand will be heavily dependent on changes in agricultural productivity.

TECHNICAL ANALYSIS OF THE FUTURES MARKET AND ITS RELATION TO HEDGING
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ennen,   David L.
The cattle market is known for its extreme price fluctuations that can make a pauper out of a prince.  The boom or bust nature of the industry is nothing new, as the change in prices can be fairly dramatic.  Since the price that a cattle feeder receives for his cattle has a large impact on his profits, the severe price changes have had a major impact on the variation in net profits for cattle feeders.  If a cattle feeder is going to reduce his price risk by using selective hedging, he has to either (a) be a good price forecaster or (b) have some strategy that is less subjective than price forecasting.  If his judgement is incorrect, he could be hedged when the price is increasing and unhedged when the price is decreasing, increasing the volatility of his...

Rural Poverty: Policy Options
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Musgrave,   Warren F.
Discussion of rural poverty has tended to emphasise farm poverty at the expense of rural urban poverty. There are serious problems in measuring the former but the evidence suggests that there is a sizeable group of chronically poor farm people. Only the Rural Adjustment Scheme appears to have components specifically geared to poor farmers and it, together with some possible innovations, is discussed. The nature and extent of rural urban poverty and its comparative neglect is described and some policy initiatives, revolving mainly round existing institutions and services are presented.

Ensaio de épocas de plantio sobre várias características agronômicas na cultura de soja (Glycinemax (L.) Merrill), variedades "Júpiter", "Prata", "Oriente" e "Pelicano", em Aripuanã-MT
Provedor de dados: Acta Amazonica
Autores: Yuyama,Kaoru.
Resumo Quatro épocas de plantio, espaçadas de 15 em 15 dias, iniciando-se em 04 de dezembro, foram utilizadas num ensaio de campo instalado no Campo Experimental do INPA-Aripuanã, com o objetivo de estudar os efeitos das épocas de plantio sobre várias características agronômicas das variedades de soja Júpiter, Prata, Oriente e Pelicano, durante o ano agrícola de 1975/77. O delineamento experimental utilizado foi o de parcelas subdivididas em blocos ao acaso, com quatro repetições, sendo as épocas consideradas como parcelas e as variedades como subparcelas. Os resultados obtidos mostram que: com um atraso no plantio, há uma diminuição de ciclo da planta, seja no período vegetativo seja no reprodutivo (com exceção das variedades Júpiter e Prata), sendo isto...

Provedor de dados: Acta Amazonica
Autores: Thatcher,Vernon E.
Resumo O Amazonadistoma negrensis n. gen., n. sp. (Trematoda : Digenea : Gorgoderidae) foi descrito de um peixe amazônico chamado "sarapó-de-bico", Gymnorhamphichthys hypostomus Ellis (Gimnotoidea : Rhamphichthyidae). O novo gênero é semelhante ao Phyllodistomum, do qual difere por ter a porção posterior do corpo grosso, musculoso e com corrugações laterais; cecos com divertículos; alças uterinas extracecais na região posterior; uma vesícula seminal sinuosa. Também existem diferenças quanto ao habitat, sendo encontrado no intestino do hospedeiro em vez da bexiga urinária. O A. negrensis, sendo totalmente negro, só se permitiu estudá-lo depois de descoloração por cinco semanas numa solução de 1% de amônia. Esta é a primeira citação de um trematódeo negro, e...

Comportamento dos nucléolos e mitocôndrios durante a ovogênese de peixes teleósteos de àgua doce
Provedor de dados: Acta Amazonica
Autores: Cruz-Landim,Carminda da; Cruz-Höfling,Maria Alice da.
Resumo Os ovócitos de peixes teleósteos em fase pré-vitelogênica apresentam numerosos nucléolos localizados perifericamente no núcleo. Existem evidências morfológicas da passagem do material destes nucléolos para o citoplasma onde se associa a mitocôndrios e se dispersa, mantendo sempre a associação. Este material pode ser detectado no ovocito mesmo após o início da deposição de vitelo possivelmente vindo a constituir o plasma germinativo.

Previsão da produção bovina na rodovia Transamazônica do Brasil
Provedor de dados: Acta Amazonica
Autores: Fearnside,Philip M.
Resumo O governo brasileiro está atualmente promovendo o desenvolvimento de pastagens para gado em vastas áreas da Bacia Amazônica, por meio de um programa de incentivos fiscais e tributários. Este fato tem sido encorajado por declarações recentes, de que as pastagens melhoram a qualidade dos solos, possivelmente podendo propiciar uma produção bovina por tempo indeterminado. Cálculos da produtividade bovina prevista para áreas, como as adjacentes à rodovia Transamazônica. feitas por vários métodos, levam à conclusão que as expectativas são demasiadamente otimísticas. O presente trabalho desenvolve equações para a previsão de produção de gado, numa área de estudo ao longo da Transamazônica, levando em consideração os efeitos dos nutrientes do solo e a...

Studies of the vegetation of a white-sand black-water igapó (Rio Negro, Brazil)
Provedor de dados: Acta Amazonica
Autores: Keel,Shirley H. Kuo; Prance,Ghillean T.
Summary The vegetation analysis of a Central Amazonian igapó, a forest under severe environmental stress — poor soil and seasonal flooding, reveals the existence of the dominant species Myrciaria dubia with a M.I.V. 75. The Shannon diversity index of this forest is 4.358 bits per individual, of which 75.73% is attributable to the evenness value. Species distributions change along the moisture gradient. Though many species exhibit the tendency of zonal distribution, the boundaries of zones are not abrupt. The authors suggest that species distribution is the result of physiological difference to flood tolerance. Further research should be directed to the comparison of flood tolerance of the plants which occur in the following three areas: permanent...

Provedor de dados: Acta Amazonica
Autores: Charlwood,J. Derek.
Resumo Estudo sobre Culex quinquefasciatus Say, um vetor potencial da filariose urbana em Manaus, Amazonas. Foram realizadas coletas de populações no ato de picar e em repouso. Os estágios de desenvolvimento ovariano e paridade foram determinados pelo exame do aspecto externo do abdome e a dissecção para dilatações de ovaríolos. A maioria das fêmeas parece repousar após a ovoposição antes de voltar a alimentar-se. O ato de picar ocorria dentro das casas, com picos ao entardecer e por volta da meia-noite. A mortalidade diária era semelhante à das áreas em que ocorre a transmissão de filariose. Coletas com armadilhas, dos individuos em repouso, indicaram que ocorrem pequenas flutuações em números durante o ano, e a análise de 274 refeições de sangue...

Resumo Oito variedades de soja do Instituto de Agricultura Tropical da Nigéria (IITA) foram testadas no Amazonas, acrescentando germcplasma valioso à soja que foi anteriormente plantada, na várzea, em programas de melhoramento. Uma das características dessas variedades é a insensibilidade fotoperiódica e a alta produtividade em ambientes tropicais. O máximo rendimento obtido neste experimento foi de 1145 kg por hectare pela variedade TGM 256-1-B. Devido terem sido plantadas a 24-11-1976, as variedades ficaram expostas a condições climáticas extremamente desfavoráveis durante os estágios críticos de crescimento. Muitas linhagens apresentaram excelentes características fotoperiódicas que, sem dúvida alguma, terão uso prático em futuros programas de...

Ocorrência de Kielmeyera nos "campos de Humaitá" e a natureza dos "campos" — Flora da Amazônia
Provedor de dados: Acta Amazonica
Autores: Kubitski,Klaus.
Summary Several authors have repeatedly emphasized the floristic and physiognomic similarity between the Amazonian "campos" which are savanna islands surrounded by high forest, and the cerrado vegetation of Central Brazil. Consequently, it was suggested that these savanna islands be the remnants of a former epoch when a cerrado type vegetation extended over large parts of tropical America. It is shown, however, that those tree species of the cerrado flora which are characterized by heavy, gravity-dispersed diaspores, as for instance Caryocar brasiliense, are absent from the "campos". On the other hand, a high proportion of the "campos" elements is provided with lightweight, alate diaspores edapted for dispersal by wind; other members of this vegetation...

Provedor de dados: Acta Amazonica
Autores: Alencar,Jurandyr da Cruz; Magalhães,Luis Mauro S.
Resumo A germinação de sementes de doze espécies florestais da região de Manaus foi investigada visando-se a obter informações para cultura destas espécies. Curvas de percentagem de germinação em função do tempo foram feitas, mostrando as distinções entre espécies quanto ao valor cultural destas sementes, assim como o período e a percentagem de germinação. Testes adicionais foram realizados (pureza, corte, flutuação e peso) dando uma caracterização melhor aos lotes estudados. Os autores apontam um bom potencial germinativo para estas espécies, sendo que nove delas apresentaram uma percentagem de germinação acima de 50% sem qualquer tipo de tratamento, num período máximo de 90 dias após a semeadura.

Provedor de dados: Acta Amazonica
Autores: Almeida,Ronaldo de; Salati,Eneas; Nova,Nilson Augusto Villa.
Resumo Medidas de radiação solar global e direta utilizando-se os filtros OG-530, RG-630 e RG-695 foram realizadas em Manaus-INPA. Os equipamentos disponíveis para estas medidas foram um piranômetro espectral e um pireliômetro de incidência normal da Eppley. Os sinais foram registrados com o auxílio de um potenciógrafo LEEDS e NORTHRUP modelo SPEEDOMAX-W. As medidas foram realizadas em dois dias claros. Com os dados obtidos foi possível estimar a variação horária do coeficiente de transmissão atmosférica correspondente a cada uma das faixas espectrais. Os autores apresentam uma distribuição horária dos fluxos de radiação solar global direta e difusa.

Resumo Variações anatômicas nas folhas de Bertholletia excelsa (Castanha-do-pará) coletadas a diferentes alturas da mesma árvore são apresentadas aqui. Encontrou-se que da base para a copa da árvore (com as condições tornando-se gradualmente mais xéricas) o número de estômatos/mm2 aumentou, o mesófilo tornou-se mais espesso, as folhas diminuíram de tamanho e o número de vasos aumentou. Estes resultados diferem do que foi encontrado para Pogonophora schomburgkiana (Leite &amp; Lleras, 1978) onde as diferenças estatisticamente significantes foram entre os estratos basal e médio, enquanto em Bertholletia foram entre os estratos médio e apical. Isto foi considerado como refletindo diferenças em condições de crescimento e não no mecanismo de variação fenotípica...

Litter decomposition and Ectomycorrhiza in Amazonian forests. 1. A comparison of litter decomposing and ectomycorrhizal Basidiomycetes in latosol-terra-firme rain forest and white podzol campinarana
Provedor de dados: Acta Amazonica
Autores: Singer,Rolf; Araujo,Izonete de Jesus da Silva.
Abstract Application of a mycosociological method (adaptation of the Lange method) in Central Amazonia produced the following results: In the white-sand podzol campinarana type of forests the dominant trees are obligatorily ectotrophically mycorrhizal; litter is accumulated as raw humus as a consequence of ectotroph dominance; fewer leaf inhabiting litter fungi occur in the dry as well as the wet seasons than are counted in the latosol terra-firme rain forest, and the fungi of that category are most strongly represented ("F-dominance") by other species here than in the terra-firme stands tested. The ectomycorrhizal trees and fungi are enumerated. On the other hand, in the terra-firme forest, ectotrophically mycorrhizal fungi did not occur in the test...

Diferenças ultra-estruturais entre bexigas natatórias de peixes teleósteos de respiração aquática e respiração aérea facultativa
Provedor de dados: Acta Amazonica
Autores: Cruz-Landim,Carminda da; Cruz-Höfling,Maria Alice da.
Resumo O presente trabalho refere-se às diferenças infra-estruturais entre a bexiga natatória do jeju (teleósteo de respiração aérea facultativa) e do aruanã (teleósteo de respiração exclusivamente aquática ou branquial). Histologicamente, em ambos os casos, a parede da bexiga natatória se mostrou constituída por um epitélio, limitando a luz, com uma lâmina própria de tecido conjuntivo muito rico em colágeno, seguida de uma camada de musculatura lisa e uma adventícia. Os resultados sugerem que a adaptação à função respiratória na bexiga natatória do jeju refletem-se na diminuição da espessura da cobertura epitelial da câmara posterior, na presença desse epitélio de possíveis substâncias surfactantes que são eliminadas para a luz e na grande vascularização...

Resumo Um estudo foi conduzido sobre o comportamento de acasalamento de linhagens de Culex quinquefasciatus Say do Gâmbia, África Ocidental e Amazonas. Brasil. Usando um sistema de televisão sensível ao infravermelho para observação no "escuro", os experimentos mostraram que os machos são atraídos pela emissão de som no vôo da fêmea e pareceram não distinguir entre membros de suas espécies e de outros gêneros. A resposta dos machos à emissão de som artificial de vôo da fêmea tem um pico em L.D. 12:12 na hora seguinte à interrupção da luz no laboratório e apresenta um padrão circadiano em escuro constante. No campo, o acasalamento foi observado quando os machos estavam em enxame voando ativamente. A conclusão obtida é de que o acasalamento depende da...

Consumo de alimentos e alguns nutrientes em Manaus, Amazonas. 1973-4 ()
Provedor de dados: Acta Amazonica
Autores: Shrimpton,R.; Giugliano,R.
Resumo Dados de consumo de alimentos e ingestão de nutrientes na Amazônia são escassos. Foram analisados dados já existentes da Primeira Pesquisa sobre Orçamentos Familiares feita entre 1.200 famílias de Manaus, em 1973 e 1974, pela CODEAMA. A dieta caracteriza-se pelo baixo consumo de verduras, legumes, frutas e leguminosas secas, além do alto consumo de peixe, pão e farinha de mandioca. Do ponto de vista quantitativo a dieta parece suficiente ao nível familiar, mas em termos qualitativos é deficiente, com níveis baixos de Vitaminas A e B. Medidas e políticas capazes de melhorar esse quadro em relação aos problemas de Saúde Pública atuais e futuros, são discutidas.

Notas preliminares sobre os morcegos do Parque Nacional da Amazônia (Médio Tapajós)
Provedor de dados: Acta Amazonica
Autores: Reis,Nelio Roberto dos; Schubart,Herbert O. R.
Resumo Estudo sobre morcegos realizado no Parque Nacional da Amazônia, localizado em terras do Pará e Amazonas com 1.000.000 de hectares. Cento e trinta e três indivíduos de 17 espécies de 5 famílias foram capturados, sendo que 12 espécies pertencem à família Phillostomidae. O gênero Carollia é o mais comum. Conclui-se que a coexistência de muitas espécies em um único local é possível devido à diversificação do hábito alimentar. Morcegos frugívoros foram os mais coletados, mas foram encontrados ainda insetívoros. nectarívoros e hematófagos. Foi feita uma comparação da fauna de morcegos entre Manaus, Parque Nacional da Amazônia e Belém: somente 11% das espécies são comuns aos 3 lugares, sendo que a fauna do Parque mostra maior afinidade com a de Manaus.

Provedor de dados: Acta Amazonica
Autores: Fearnside,Philip M.
Summary This paper presents a brief overview of the process of desertification on a world wide scale, and explains how individual factors contributing to this process apply to different regions of Brazil. Human activities have often been significant causes of climatic change in the direction of dryness, obten in combination with geographical factors such as global air circulation patterns, mountain rainshadows. and cold ocean currents. The key role of human overexploitation is documented in a more detailed examination of the specific example of the Rajasthan Desert in north-western India. The role of atmospheric dustiness resuiting from overgrazing and cultivation of marginal lands has been a particularly important factor in the case of this overpopulated...

Autores: Bandeira,Adelmar G.
Resumo Foram estudadas a distribuição e diversidade de cupins em áreas de floresta primária, capoeira e pastagem na Amazônia Central, Estado do Amazonas. Foram feitas medidas de umidade do solo, compactação do solo (taxa de infiltração de água no solo) e temperaturas do solo e do ar, para estabelecer relações com a distribuição dos cupins. Com um esforço de coletas aproximadamente equivalente nos três ambientes, ficou demonstrado que a maioria dos gêneros se distribui nos três habitats. Nasutitermes foi o gênero mais comum e com maior diversidade, sendo mais freqüente em pastagem. O número total de ninhos de cupins foi também maior na pastagem que na floresta primária. Os cupins do solo podem atingir quase um metro de profundidade e seu número foi maior na...

Provedor de dados: Acta Amazonica
Autores: Lawrence,Dale N.; Facklam,Richard R.; Sottnek,Frances O.; Hancock,Gary A.; Neel,James V.; Salzano,Francisco M.
Resumo O pioderma foi estudado em uma amostra representativa entre residentes de 4 remotas aldeias indígenas no Estado do Amazonas, Brasil, durante os meses de julho a agosto de 1976. A prevalência entre os 775 habitantes examinados foi de 11%, com pequena variação inter-aldeia. Quanto às taxas de ataque, estas foram calculadas para toda a amostra da população, em intervalos de 5 anos de idade, sendo que os indivíduos de 0-4 anos tiveram a taxa mais alta, 31%. A prevalência mais alta, 38%, foi encontrada entre os de 3 anos de idade. As taxas de ataque aparentemente não tiveram nenhuma relação quanto ao sexo. Culturas de lesões de pioderma representativas tomadas de pessoas nas quatro aldeias pesquisadas e em três aldeias adicionais, foram estudadas...

Avaliação da Jari Florestal e Agropecuária Ltda. como modelo para o desenvolvimento da Amazônia
Provedor de dados: Acta Amazonica
Autores: Fearnside,Philip M.; Rankin,Judy M.
Summary The present paper emphasizes the importance of a thorough evaluation of Jari Florestal e Agropecuária Ltda. as a model for development in the Amazon. This large scale commercial, plantation and agriculture venture has been suggested recurrently by various Brazilian planners as an appropriate model for development of other areas in the region. Jari is undertaking enormous silvicultural projects using Gmelina arborea and Pinus caribaea in "terra firme" (high ground) areas, and a mechanized agriculture scheme with irrigated rice culture in "várzea" (floodplain) areas. Based on observations and interviews made during visits to those projects, three principal questions are identified which need to be studied in order to evaluate the applicability of...

Dinâmica estacional de uma população de Anopheles darlingi, numa área endêmica de malária no Amazonas
Provedor de dados: Acta Amazonica
Autores: Hayes,Jack; Charlwood,J. Derek.
Resumo A atividade de picadas do Anopheles darlingi foi estudada por mais de um ano numa área endêmica de malária na BR-174 (Manaus/Boa Vista). Esta atividade foi documentada para demonstrar as mudanças estacionais na população e variação do ciclo nas estações do ano. São apresentadas as coletas mostrando o ciclo de picada dentro e fora das casas. O modelo foi constante na área estudada e verificou-se que a população de A. darlingi aumenta na estação seca. Com o aumento das chuvas há um declínio na população de anófeles e esta diminuição corresponde a um decréscimo estacional similar ao número de casos de infecção malárica.

Provedor de dados: Acta Amazonica
Autores: Kitajima,E. W.; Noda,H.; lin,M. T.; Pahlen,A. van der.
Resumo Um levantamento preliminar de viroses de plantas cultivadas nos arredores de Manaus foi feito em março de 1977. Diversas propriedades particulares e campos experimentais foram inspecionados, anotando-se as plantas exibindo sintomatologia suspeita. A verificação da sua possível etiologia viral foi feita através de testes de transmissão, serologia e exames electrono microscópicos. Foram constatadas diversas viroses em tomateiro, pimentão, quiabeiro, feijoeiro, cucurbitáceas, soja, feijão-de-asa, milho. etc. Como regra geral, ao contrário do que sucede no Sul do País, as viroses transmitidas por afídeos foram de ocorrência rara, presumivelmente porque as condições climáticas da região seriam desfavoráveis à biologia desses insetos.

Quelônios aquáticos da Amazônia: um recurso ameaçado
Provedor de dados: Acta Amazonica
Autores: Smith,Nigel J. H.
Resumo Os quelônios aquáticos têm servido o homem, há muito tempo, como um importante recurso alimentar. Durante o período colonial, comerciantes portugueses perturbaram praias de desova em grande escala à procura de ovos, os quais eram utilizados como óleo para cozinhar e iluminar. Isto foi aumentando intensamente e, pelo fim do século 19, populações de tartarugas declinaram drasticamente. Apesar de a legislação ter passado a protegê-las, a fiscalização não é suficiente e as tartarugas estão sofrendo crescente pressão do homem, não apenas para comida, mas também pela modificação de seu ambiente.

Fenologia do pau-rosa (Aniba duckei Kostermans), Lauraceae, em floresta primária na Amazônia Central
Provedor de dados: Acta Amazonica
Autores: Magalhães,Luís Mauro Sampaio; Alencar,Jurandyr da Cruz.
Resumo Os autores estudam as diversas fases fenológicas (floração, frutificação e mudança foliar) de Pau-rosa (Aniba duckei Kostermans), Lauraceae, em floresta primária tropical, próxima a Manaus. Foi observado o comportamento desta espécie e relacionado com as demais existentes na mesma área. A espécie apresenta mudança foliar anualmente, o que não acontece para as fases de floração e frutificação. Quando presente, a floração ocorreu sempre no período mais úmido. Dadas a irregularidade na floração — frutificação, e a grande predação dos frutos por Psitacídeos, verificada pelos autores, o fornecimento regular de sementes fica comprometido, havendo necessidade de pesquisarem-se novas formas de propagação para a espécie.

Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz
Autores: Nakagawa,Júlio; Neptune,André M. Louis; Polastre,Rinaldo; Savy Neto,Ângelo.
O presente trabalho teve como objetivo estudar os efeitos de doses crescentes de fósforo na produção, no teor de óleo das sementes e nas concentrações de macronutrientes, exceto o S, das sementes e da casca da mamona, em cultivar 'Guarani'. As doses utilizadas foram 0-40-80-120-160-200 kg/ha de P2O5, num Latossolo Vermelho Escuro - fase arenosa de baixa fertilidade, no Município de São Manuel, Estado de São Paulo. Os resultados mostraram que o fósforo aumentou o número de frutos por cacho, diminuiu a porcentagem de casca no fruto e aumentou o peso de sementes por cacho. Disto resultou um aumento médio na produção de 100,21%, em relação à produção do tratamento sem fósforo. No que tange aos teores dos elementos nos frutos, observou-se um aumento de P e uma...

Os tratamentos constaram na imersão de frutos de 'Haden' em água aquecida nas temperaturas de 45, 50, 55 e 60°C, usando-se para cada temperatura, 3 tempos de exposição 10, 20 e 30 minutos. Apos os tratamentos os frutos foram tratados com o ácido cloroetilfosfônico (Ethefon) a 500 ppm e o experimento foi encerrado no 10º dia após a execução dos tratamentos, com os frutos já maduros. Os melhores tratamentos foram aqueles a 50°C por 30 minutos e a 55°C por 10 minutos, resultando em controle praticamente total da antracnose, Colletotrichum gloeosporioides Penz, e não alteraram nem a aparência, nem os teores de ácidos e sólidos-solúveis dos frutos. Imersões em água a 55°C por 20...

Condicionadores químicos do solo e seus efeitos sobre os Índices físicos
Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz
Autores: Freire,Wesley Jorge; Moretti Filho,Justo.
Dois condicionadores químicos, a carboximetilcelulose, nas dosagens de 0,1% e 0,25% em relação ao peso do solo seco, e o silicato de sódio, de relação sílica-álcali igual a 3,2, a 0,6% e 1,2% em peso, foram pesquisados quanto aos seus efeitos sobre os índices físicos dos solos argiloso e barro arenoso empregados neste trabalho. Os dados obtidos foram estatisticamente analisados e os resultados permitiram que se chegassem a algumas conclusões. O tratamento 0,25% de carboximetilcelulose diminuiu o peso específico aparente seco e aumentou, consequentemente, o índice de vazios e porosidade dos solos estudados. O efeito dos tratamentos 1,2% de silicato de sódio e 0,1% de carboximetilcelulose sobre o peso específico aparente seco dos solos argilosos e barro...

No programa de melhoramento da Seção de Algodão do Instituto Agronômico, freqüentemente são obtidas linhagens melhoradas que não podem ser lançadas na lavoura do Estado de São Paulo por serem suscetíveis ao fungo da murcha de Fusarium. Tal foi o caso da IAC 67/59, híbrido entre variedades paulistas e mocó. Foi projetada a transferência de resistência ao patógeno para essa linhagem a partir da variedade 'IAC 17'. Realizaram-se cinco retrocruzamentos para a IAC 67/59, sem passagem por gerações autofecundadas, assegurando-se a retenção dos heterozigotos para resistência através de uma técnica de inoculação em caixas de germinação, nas gerações retrocruzadas. Estas e as gerações F1 e F2 foram comparadas em testes de campo com infestação natural pelo agente...

Autores: Van Raij,Bernardo; Cantarella,Heitor; Zullo,Marco Antônio Teixeira.
O método tampão SMP de determinação da necessidade de calagem foi estudado em 23 amostras de solos do Estado de São Paulo. A calibração do método foi feita através das necessidades de calagem para valores de pH de 5,5, 6,0 e 6,5 obtidos de curvas de neutralização dos solos com CaCO3. Foram testadas três relações de solução-tampão e solo, optando-se por uma modificação que deu ao método maior sensibilidade para baixas necessidades de calagem, se comparada com a metodologia original. Foi feita a comparação do método SMP com outros critérios de determinação da necessidade de calagem. O método SMP é eficaz para determinar a quantidade de CaCO3 para atingir determinado valor de pH do solo. Tal não acontece com o cálculo baseado na relação entre pH e saturação...

Foi estudado, na experimentação com o algodoeiro, o efeito das falhas sobre a produção, assim como a respectiva correção, considerando-se que a produção média por planta é função da área média aproveitada pela mesma. A função adaptada foi, originalmente, um polinômio de terceiro grau, mas a hipótese de linearidade aproximou satisfatoriamente a realidade dentro dos limites dos espaçamentos usuais na lavoura. Admitida essa linearidade, estudou-se uma metodologia de correção do efeito das falhas com a observância de um limite de desconto além do qual as plantas adjacentes não aproveitariam a área livre. É proposta a seguinte operação de ajuste: N Y1a = k1Y1 - b(k1A1 - Sk1A1/N) i = l e b = S (k1A1) (k1Y1) - (Sk1A1) (Sk1Y1)/N S (k1A1)² - (Sk1A1)²/N Para cada...

Infrutíferos todos os trabalhos visando ao melhoramento de Agave sisalana Perr., por meio de propagação sexual, os estudos voltaram-se para outras espécies, dentre elas duas diplóides: o A. amaniensis e o A. angustifolia: a primeira se caracteriza por apresentar folhas grandes e de boa conformação e, a segunda, por produzir elevado número de folhas. Nesse estudo utilizou-se A. amaniensis e seu híbrido com A. angustifolia. Os indivíduos obtidos (F2) apresentaram grande variação nas suas características, mas só foram estudadas as plantas de porte semelhante ao de A. sisalana. Dentre esses indivíduos, alguns se destacaram por apresentar produção total e produção média anual de fibras bem superiores àquela obtida normalmente com o sisal comum.

São propostas equações matemáticas para estimar o total diário de horas abaixo de determinada temperatura-base, em certo período, utilizando-se somente dos valores diários das temperaturas máxima, mínima e das 21 horas (hora local). A comparação entre os totais diários e mensais de "horas de frio" estimados pelas equações propostas e os observados através de termogramas, para várias localidades do Estado de São Paulo, mostrou boa concordância entre os métodos de cálculo. O modelo proposto dispensa o uso de registros contínuos de temperatura. As vantagens de tal estimativa residem na maior disponibilidade de registros de temperaturas máximas, mínimas e das 21 horas, permitindo maior densidade de pontos em trabalhos de zoneamento agroclimático e de...

Provedor de dados: Bragantia
Autores: Lago,Antônio A. do; Banzatto,Nicolau V.; Savy Filho,Angelo; Godoy,Ignácio J. de.
Determinaram-se, a cada três meses, as porcentagens de germinação de sementes da ponta, meio e base das hastes de dois cultivares de gergelim, colhidas na época usual, secas a 35°C por doze dias, embaladas em sacos de papel e armazenadas em condições não controladas de laboratório na região de Campinas (SP), por um período total de 24 meses. As sementes dos dois cultivares se conservaram muito bem, com germinação acima de 80% após os dois anos de armazenamento. As sementes do cultivar venezuela 51 apresentaram germinação um pouco mais alta do que as do cultivar morada. Em ambos, praticamente não ocorreram diferenças significativas de germinação entre sementes extraídas da ponta, meio ou base das hastes.

Adubação da cana-de-açúcar: XV - experimentos com micronutrientes nas regiões canavieiras do estado de São Paulo
Provedor de dados: Bragantia
Autores: Alvarez,Raphael; Wutke,Antônio Carlos Pimentel; Arruda,Hermano Vaz de; Godoy Júnior,Gentil.
São apresentados os resultados de 23 experimentos em regiões canavieiras paulistas, para avaliar possíveis respostas da cana-de-açúcar a micronutrientes. Fizeram-se aplicações isoladas de sulfato ferroso, tetraborato de sódio, sulfato de cobre, sulfato de zinco, sulfato de manganês e molibdato de amônio, nos sulcos de plantio e na presença de adubação NPK Em apenas um dos experimentos verificou-se efeito significativamente favorável à aplicação de micronutrientes, no caso, cobre e molibdênio. Com base nos resultados obtidos, corroborados por análises foliares em trabalho paralelo e conduzido à mesma época, concluiu-se que, nas condições do ensaio, deficiências de micronutrientes não constituem problema para a lavoura canavieira no Estado de São Paulo.

Estimativa e mapeamento do número de horas com temperaturas abaixo de 7 e 13°C no Estado de São Paulo e análise comparativa do comportamento de fruteiras de clima temperado constituem os objetivos do presente trabalho. Foi cotado o número de horas com temperaturas inferiores a 7 e 13°C, índices considerados limites necessários à dormência dessas plantas. Foram selecionados termogramas de doze postos agrometeorológicos do Instituto Agronômico, situados em altitudes variáveis entre 25 e 1.000m, correspondentes ao período 1964-1973. Estabeleceram-se equações para estimativa do número de horas com temperaturas inferiores a 7°C (HF-7) e 13°C (HF-13) em função da temperatura média do mês de julho, cujos coeficientes de correlação foram de -0,88 e -0,93,...

Provedor de dados: Bragantia
Autores: Teixeira,A. A.; Carvalho,A.; Fazuoli,L. C.
Analisaram-se várias características morfológicas de amostras de sementes e a qualidade do produto de alguns cultivares de Coffea canephora e de C. congensis, coletadas em quatro localidades do Estado de São Paulo. Utilizou-se uma escala de cinco pontos, desenvolvida em Angola, para avaliação da qualidade da bebida de C. canephora. Os dados obtidos foram comparados com os dos padrões kouillou de C. canephora do Estado do Espírito Santo e mundo-novo de C. arabica. Verificou-se que 46% das amostras de sementes beneficiadas foram classificadas como pertencentes a C. arabica e, 36%, a C. canephora. As porcentagens de sementes do tipo moca variaram de 10 a 50% para as amostras de C. canephora e de 20 a 40% para C. congensis. Para o mundo-novo essa porcentagem...

Autores: Ferraz,Carlos A. M.; Fava,João F. M.; Rigitano,Ayrton; Sabino,Nelson P.; Moreira,Cláudio A.; Costa,Duval S.
São apresentados e discutidos os resultados de quatro ensaios com algodoeiro, conduzidos nos anos agrícolas de 1970/71 a 1972/73, abrangendo as localidades de Araras, Paranapanema e Santo Antônio da Posse, para estudar os efeitos da colheita manual e mecânica em três variedades paulistas de algodoeiro. Os resultados mostraram que não houve interação entre processo de colheita e variedades, podendo ser considerado como bom o desempenho das variedades paulistas IAC 13-1, IAC RM3 e IAC RM4-SM5, em face da colheita mecânica. O sistema de colheita manual sempre proporcionou melhor rendimento e menor porcentagem de quebra no beneficiamento. Para as características da fibra e do fio, verificaram-se diferenças apenas para micronaire, nos quatro ensaios estudados...

Provedor de dados: Bragantia
Autores: Rodrigues Filho,Francisco S. O.; Lago,Antonio A. do; Cia,Edivaldo; Ferraz,Carlos A. M.
Estudaram-se os efeitos de quatro métodos de deslintamento na germinação e longevidade de sementes de algodoeiro do cultivar IAC 13-1, tratadas e não tratadas com o fungicida PCNB 75% e armazenadas em condições não controladas de armazém na região de Campinas (SP), por um período total de 21 meses. As sementes deslintadas por gás clorídrico e tratadas com fungicida mantiveram germinação acima de 80% até aos 15 meses de armazenamento. Aos 21 meses, as sementes que apresentaram germinação acima de 60% foram aquelas deslintadas por gás clorídrico ou ácido sulfúrico e tratadas com fungicida. Tais sementes apresentaram germinação mais alta e se conservaram melhor do que aquelas deslintadas a fogo ou mecanicamente. Independente do método de deslintamento. o...

Provedor de dados: Bragantia
Autores: Moraes,Ferdinando Roberto Pupo de; Gallo,José Romano; Igue,Toshio; Figueiredo,Joaquim Ignácio de.
Foi determinada a concentração de alumínio e de manganês em folhas de cafeeiros cultivados em vasos com três solos diferentes e com aplicação de três fertilizantes nitrogenados acidificantes (nitrato de amônio, uréia e sulfato de amônio) e um não acidificante (salitre-do-chile), além de dois tratamentos extras com corretivos de acidez e um com enxofre. Nas raízes estes elementos foram também determinados para os tratamentos que receberam uréia, uréia mais enxofre e o controle sem nitrogênio. Nos três solos determinou-se o efeito dos tratamentos sobre o pH e a concentração de A1(3+) e Mn3+. A análise foliar revelou diferenças significativas entre tratamentos na concentração de alumínio e manganês das folhas e em todos os três solos estudados. Alguns...
