Abstract:
... Anthropogenic activities can have a great influence on water quality and in the availability of habitat and food resources, which can promote changes in the trophic diversity and carbon sources sustaining aquatic communities. The objective of this study was to evaluate if the trophic diversity and the main carbon sources sustaining fish communities change along a pollution gradient. The study was ...

Subject:
carbon nitrogen ratio; detritivores; ecosystems; functional diversity; natural regeneration; soil; species richness; trees; tropical forests; vegetation structure; Brazil
Abstract:
... Restoration projects may have broad and complex ecological goals that require distinct and integrative measures for evaluating restoration development and success. However, most studies usually evaluate structural and species composition parameters, with less emphasis on ecological processes and functioning. The main objective of this study is to use an integrated approach that considers structura ...
