Species abundances and functional traits data of frog assemblages in Amazonian forests (Tapajós FLONA and Alter do Chão village, Brazil)

We sampled frogs along an edaphic and vegetation-structure gradient in the
Brazilian Amazon. We sampled 33 plots organized in four modules (with 10,
6, 8 and 9 plots). Environmental data are composed of are litter
depht(cm), distance to water bodies (m), temperature (ºC), vegetation
structure (PCA axis), soil sand and silt content (g-kg), and proportion of
the area deforested. Additionally, we measured snout-vent length (SVL) and
leg length relative to SVL and evaluated the effects of environmental
variables on thirteen binary traits used with presence or absence.
