Amazonian rainforests once thought to hold an innate pristine wilderness, are increasingly known to have been densely inhabited by populations showing a diverse and complex cultural background prior to European arrival. To what extent these societies impacted their landscape is unclear. Amazonian Dark Earths (ADEs) are fertile soils found throughout the Amazon Basin, created by pre-Columbian societies as a result of more sedentary habits. Much is known of the chemistry of these soils, yet their...

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

Kelly Torralvo, Rafael De Fraga, Albertina Lima & William Magnusson
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...
