Ecologia funcional de zooplâncton e divergência genética de Anostraca (Crustacea) em lagoas temporárias tropicais do noroeste de Minas Gerais

Abstract

Environmental issues have been increasingly discussed today, and many ways have been sought to measure ecosystems’ biodiversity. In addition to the taxonomic diversity, one of the possible alternatives used to obtain information about the diversity of the communities is the functional diversity, which considers the functional attributes (traits) of each species. In this work, the zooplankton functional diversity of eight temporary aquatic ecosystems located in the northwest of Minas Gerais was studied, as well as the composition and richness of the zooplankton community of these environments. Collections were made in environments located in two municipalities of Minas Gerais, Urucuia and Lagoa Grande, from January 31 to February 2, 2017. The zooplankton community was divided, according to species attributes, into seven functional groups. Because they are small and ephemeral environments with very peculiar characteristics, the richness and density of the zooplankton community were relatively low, as well as the functional diversity. The presence of specimens of the order Anostraca, genus Dendrocephalus, seems to have influenced the composition of the zooplankton community, especially in Cladocera.
