For decades the ecologists are using the same methods in order to determine the environmental health of a community, however, the crescent need on defining how these processes act, triggered the development of new methods that could classify the organisms and their function at the habitats. Here we used the anuran larvae to understand the effects of an environmental gradient on the structure and organization of the anuran assemblages along it, and to access in a realistic form, the actual state of preservation of the largest remnant of Atlantic Rainforest on the Southernmost portion of Brazil. We found that despite the higher diversity of species and the conservation unit status of the place, the ecosystem itself is still in danger,given the low number of functional groups and thus a higher number of ecosystem services that can be lost.
