| In Malesia and Taiwan there are 6 species of Agrostis Linné (Gramineae). Agrostis rigidula Steud. has 8 varieties, 5 in Malesia and 4 (incl. one Malesian) in Taiwan. Agrostis clavata Trin. is native in Taiwan and once found in New Guinea. Agrostis gigantea Roth must be called A. stolonifera Linné var. ramosa (S. F. Gray) Veldk. and is partly native, partly introduced in Malesia. Agrostis hirta Veldk. is a new species from New Guinea. New combinations for varieties are proposed in A. rigidula and the Indian A. pilosula Trin. |

| The CENTRE OCEANOLOCIQUE DU PACIFIQUE (cap), a laboralory of the french agency CENTRE NATIONAL POUR L'EXPLOITATlON DES OCEANS (CNEXO), is located at Vairao in the southern part of TAHITI island, French Polynesia. Most of the island is surrounded with a coral reef delimitating a lagoon. Around the COP, the lagoon forms a NW-SE basin, 40 m of maximum depth, fed in oceanic water by the combing of the open-sea swell over the barrier reef, so that the renewal rate of the lagoon water is once every day or every second day according to the strength of the waves. Under those conditions, the sea water pumped at the COP offers similar features to the superficial oceanic water : annual temperature range 25.5 - 3O.1° C ; annual salinity range 34.2 - 36.5 ppt ; poor... |

| Resumo O presente trabalho trata do comportamento da alocação de recursos dos colonos em uma parte da área de colonização da Rodovia Transamazônica, e esboça os procedimentos usados para modelar este comportamento como uma simulação em computador realizada para produzir estimativas da capacidade de suporte humano. Para o propósito de reproduzir as alocações dos colonos o mais fielmente possível na simulação de computador, as decisões podem ser divididas entre alocações de subsistência e de cultura comercial. As estratégias de alocação para cultura comercial podem ser classificadas em quatro padrões de uso da terra: culturas comerciais anuais, culturas perenes, pecuária de gado, e trabalho externo. Estes padrões estão fortemente relacionados aos... |

| This paper deals with the ammonite biostratigraphy of the lower 312 m of the Miravetes Formation (sections Y and Z) exposed 500 m north and northwest of Los Miravetes along the Río Argos, 3 km west of Caravaca (SE Spain). This sequence embraces the uppermost Tithonian, Berriasian, and lower Valanginian. The succession of ammonite assemblages is similar to the one described by Le Hégarat (1971) from SE France. Le Hégarat's results are, where possible, completed and, where necessary, corrected. Arguments are adduced for a stratigraphic position of the Tithonian-Berriasian boundary, which should also be the Jurassic-Cretaceous boundary, between the Pseudosubplanites grandis and Subthurmannia (Strambergella) subalpina subzones. The Berriasian was divided into... |

| Corn leaf samples were taken at different positions of the stalk in order to find out the best correlation between N content in the leaf and grain yield. The experiment was carried out on a Ortho-Red-Yellow soil at Mococa Experimental Station. The experiment was a randomized block design with five replications. The treatments consisted of application as side dressing of 0, 30 and 60 kg N/ha as ammonium sulphate. At planting time the quantity of fertilizer applied was 300 kg/ha of the formula 4-14-8. At flowering, leaf +4, ear leaf and the leaf below and opposite to the first corn ear were sampled. The leaves from the three sampling methods and the grain yield at harvesting time were analysed for total N, P, K, Ca, Mg and S. The application of S fertilizer... |

| Na amostragem de ninfas de cigarrinhas em pastagens de Brachiaria decumbens Stapf, foi comparada a eficiência de amostragens de três quadrados de áreas: 0,0625 e 1m2. A eficiência foi maior quanto menor o quadrado. Portanto, o quadrado da área 0,0625 m2 foi recomendado. As relações entre as densidades de população e o numero de amostras necessárias para obter um certo nível de precisão foram estudadas. Vinte amostras de 0,0625 m2 bem distribuídas devem fornecer um nível de precisão de cerca de 20%. Foram elaborados gráficos demonstrando o numero de amostras necessárias, nos diferentes níveis de precisão desejados, para os diversos tamanhos de ninfas. Os procedimentos para a amostragem em parcelas pequenas e grandes, no campo, também são fornecidos. Devido... |

| In the spring of 1980, from the end of March till in July, I visited the eastern part of the Spanish province of Oviedo and the adjacent part of the province of Leon. The main subject of investigation during this period was the species Rana temporaria (Veenstra 1981). I tried to find out where this species could be found and while doing so I determined the occurrence of more species of amphibians. Totally twelve species of amphibians could be observed. Characteristics of their reproduction sites are listed and worked out below. |
