DIVERSIDADE FUNCIONAL DE COMUNIDADES DE PEIXES DE RIACHO

In the last decade there was a remarkable increase in number of studies incorporating species functional traits to quantify diversity communities (i.e., diversity). The approach has contributed advances theoretical and applied ecology. Studies developed Brazil represent significant portion world's scientific production on stream fish diversity. However, is clear bias, with most assessing communities' response natural anthropogenic environmental gradients. Other research areas such as conservation effect biodiversity ecosystem functioning are still scarce. Here we highlight conceptual methodological bases ichthyology. We discuss key questions trait selection for fish, main facets indices calculate them, general notions composition, beta null models. also address state art raised gaps perspectives advancing knowledge
