A study of sorghum production potential in the semi-arid tropic of Brazil. Infoteca-e
GARAGORRY, F. L.; PORTO, E. R.; MOITA, A. W.; SILVA, A. de S.; CHAIB FILHO, H..
The paper presents the application of a computerized agroclimatic system to the study ofsorghum production potential in the semi-arid tropic of Brazil. After a brief description of the system, the results obtainae for a sample of counties are discussed. In particular, the paper illustrates the use of clustering techniques in connection to agroclimatic zoning. The use of the system in relation to complementary irrigaton studies is also stressed.

A taxonomic revision of Harpullia (Sapindaceae) Naturalis
Leenhouts, P.W.; Vente, Magda.
The present taxonomic revision of Harpullia was started by the second author as the main part of her work for a M. Sc. in biology at Leiden University. She concentrated on a revision of the species occurring in New Guinea, paid only a more superficial attention to the rest of the genus. The first author supervised her work, completed it, and worked it up for publication. It is hoped that this taxonomic revision will be followed by two more papers, one on the pollen-morphology by Dr. J. Muller, secondly one on the systematics of the genus by the first author of the present paper. The system that will probably emanate from the last named paper is already used in the present one and, accordingly, will be sketched here. The genus is, as with Radlkofer...

A taxonomic revision of the European Sphacelariaceae (Sphacelariales, Phaeophyceae) Naturalis
Prud’Homme van Reine, W.F..
The present study deals with the taxonomy of a family of the brown algal order Sphacelariales in Europe. The taxonomy of this order is much influenced by the works of Sauvageau as published between 1900 and 1914. A short survey of the work on Spacelariales by him and his phycological predecessors is given in the introduction. The order Sphacelariales is described and its nomenclatural history is given. Other paragraphs deal with distribution, morphology and the used descriptive terminology, ecology, variability and culture studies, reproduction and life-history, systematic position and classification. In the notes on morphology the history of the descriptive terminology is incorporated, as well as discussions on the correct use of this terminology. Most...

A WILLINGNESS TO PLAY: ANALYSIS OF WATER RESOURCES DEVELOPMENT AgEcon
Martin, William E.; Ingram, Helen; Laney, Nancy K..
Economic analysis shows that the Central Arizona Project will be a poor investment from the point of view of individual farmers. Yet farmers support the Project. In this study of the economics and politics of the CAP, farmers are questioned as to their information, perceptions and motivations. Farmers are willing to play – not necessarily to pay.

Absence de captage de Crassostrea gigas dans le bassin de Marennes-Oléron en 1981 : causes et conséquences ArchiMer
Berthome, Jean-paul; Deslous-paoli, Jean-marc; Heral, Maurice; Razet, Daniel; Garnier, Jacqueline.
The want of C. gigas spat-catching in the Marennes-oleron basin in 1981 can be due to various different reasons which are analysed here. Physico -chemical and trophic factors that can induce variations in the quality of gametogenesis, are successively in comparison with the year 1979 when reproduction was good. The biochemical evolution and a study of gonads slow a lack in maturation in 1981 even during the summer period. Late maturation of gonads bring about physiological consequences which induced mortality of cultivated oysters at the end of winter. A feeble recruit and a decrease of the cultivated stock have economic consequences which here sketched up.

Absorção e translocação de fósforo em dois cultivares de mamoneira (Ricinus communis L.), 'Campinas' e 'Guarani', com uso de 32p Anais da ESALQ
Nakagawa,Julio; Neptune,André Martin Louis; Muraoka,Takashi.
Com o objetivo de estudar a absorção e translocação do fósforo na cultura da mamoneira, instalou-se um ensaio em vasos com os cultivares 'Campinas' e 'Guarani' e empregou-se o fósforo radioativo (32p) como traçador. Os quatro tratamentos constaram da aplicação ao solo de 65 ppm de P contendo 32p, quando as plantas apresentavam seis, nove, doze e quatorze folhas, respectivamente e cortadas com nove, doze e quatorze folhas e as do quarto tratamento após 21 días da aplicação do fertilizante marcado. Através dos dados obtidos, pode-se concluir que, neste solo com baixo teor de fósforo, a aplicação deste elemento, na época da emissão de ínflorescências primárias, não influi no desenvolvimento das inflorescências, uma vez que se formam as expensas de fósforo...

Ação predadora do tucunaré (Cichla ocellaris) sobre a tilapia do congo (Tilapia rendalli) (Osteichthyes, Cichlidae) Zoologia
Nomura,Hitoshi; Menezes,J. F. S.; Souza,M. B. F. A..
An extensive cuivivation of the cichlids Tilapia rendalli and its predator Cichla ocellaris was undertaken at a lake in the Ribeirão Preto (State of São Paulo) Campus of the University of São Paulo. Comparison of the results with former ones, obtained before the introduction of the predator, showed a considerable increase of tilapias, both in total length and total weight, showing the advantage of rearing them together.

Accumulation du cadmium par Mytilus edulis en présence de bactéries marines sensibles ou résistantes à ce metal ArchiMer
Flatau, Gilles N.; Gauthier, Michel J.
The cadmium accumulation by the soft parts of the mussels increased in the presence of the sensitive strain, and was lower in the presence of the resistant strain, when only ionic metal was given to the mussels. The metal brought by previously contamined and killed bacteria was more accumulated by the different organs than when it was provided in the ionic form, and was more accumulated by viscera and gills when it was bound to the resistant bacteria.
