“…Normally in surveys, EIAs select the taxa to be sampled and almost always choose birds and mammals in fauna and flora, tree species, which considerably limits the quality of the studies, especially regarding biodiversity and interactions between species in a given ecosystem (Santos, 2003). In general, and especially in Brazil, the description of invertebrate biodiversity in biological communities has been restricted to classical quantitative aspects such as taxa composition, richness indices, equitability and morphospecies diversity, such as Simpson and Shannon Wiener (Corrêa et al, 2006;Podgaiski et al, 2007;Campos et al, 2009). Although traditional, these taxonomic indicators assume an equal functional weight for all species in the community, regardless of their characteristics, requirements and functions.…”
