متن کاملThe fish community of the Sorocaba River Basin in different habitats (State of São Paulo, Brazil).
A fish assemblage study was accomplished in different habitats of the Sorocaba River Basin. Fish were caught with gillnets, were weighed (weight total - g) and measured (standard length - mm). Several abiotic variables of selected sampling sites were measured in order to characterise their habitats in order to attempt establishing correlations with fish community traits. Fish numbers per specie...
متن کاملFish-assemblage structure of the Corumbatai river basin, São Paulo State, Brazil: characterization and anthropogenic disturbances.
The Corumbataí river is one of the main tributaries of the right margin of the Piracicaba river, itself a tributary of Tietê river. The Corumbataí is part of the Paraná river basin and is regionally important not only because of its good-quality water but also because the local landscape has unique features. This study aimed to characterize the fish assemblage of the Corumbataí in order to prov...
متن کاملDiet of fishes in Passa Cinco stream, Corumbataí River sub-basin, São Paulo state, Brazil.
The aim of this study was to describe and classify the food preference of fish species in Passa Cinco stream. The grade of feeding preference was applied to stomachs considered replete. This method consists of attributing values to food items found in certain species, according to the participation of each item in the analysed stomach. We analysed 576 full stomachs of 28 species. The autochthon...
متن کاملDissolved Black Carbon in the Headwaters-to-Ocean Continuum of Paraíba Do Sul River, Brazil
Rivers annually carry 25–28 Tg carbon in the form of pyrogenic dissolved organic matter (dissolved black carbon, DBC) into the ocean, which is equivalent to about 10% of the entire riverine land-ocean flux of dissolved organic carbon (DOC). The objective of this study was to identify the main processes behind the release and turnover of DBC on a riverine catchment scale. As a model system, we c...
