Effect of Two Geologically Distinct Amazonian Rivers in Shaping Forest Understorey Bird Assemblages
ABSTRACT Aim The effects of rivers as barriers for species dispersal can be expected to vary according to both species traits and the characteristics of rivers themselves. In this context, our aim was to investigate dissimilarities in species composition across opposite banks of two major Amazonian rivers, the Juruá and the Tapajós, and relate them to ...
