Última A ictiofauna da bacia do Rio Paraíba do Sul. Biodiversidade e padrões biogeográficos BABT Bizerril,Carlos Roberto S. Fontenelle. Fish fauna taxonomic composition and biogeographic informations of the Paraíba do Sul river basin are presented. Samples were taken in 75 units between January/1995 and June/1998. Species were identified and classified according its distributional pattern. Biogeographic analyses were conduced using macro, meso and micro scales. A total of 167 species were sampled, being 37 marine species. Among the marine taxa, Awaous tajasica and Oosthetus lineatus seems to spend their whole life histories in the freshwater environments. Sixteen species were introduced in the basin. Most of the native taxa inhabit the rivers’storage zone, mainly in pools. Faunistic similarities between the Paraíba do Sul river basin and other Brazilian rivers suggest that the environment...

Fontenelle. The relationship between the physical environment and the biological diversification of fish communities was studied and the use of fluvial morphology as an indicative of priority areas for conservation was examined. As a case study the upper course of rio Macacu, State of Rio de Janeiro, Brazil was selected. Biotic data were obtained during 4 year of samples, conduced in 13 sample units. Each environment explored were characterized for its area, order, extension, slope and number of tributaries. Two new indices (environmental diversity and environmental turnover ratio) were proposed. To asses the correlation between the physical and biotic matrixes the data were compared using the Mantel test. A strong correlation between the physical variables and...
