Aim To assess ancient biotic connections between the Amazon Forest (AmF) and the
Atlantic Forest (AtF) based on environmental niche modelling (ENM), palaeobiological, and …

True toads of the genus Rhinella are among the most common and diverse group of

Abstract During Paleogene the Neotropical region was mainly covered by rainforests and
ancient Amazon (AM) and Atlantic Forest (AF) were continuous and interconnected. The …

Species distributed across vast continental areas and across major biomes provide unique
model systems for studies of biotic diversification, yet also constitute daunting financial …

Aim For many taxa, inaccuracy of species boundaries and distributions hampers inferences
about diversity and evolution. This is particularly true in the Neotropics where prevalence of …

Recent studies suggest increasing sensitivity to orbital variations across the Eocene-
Oligocene greenhouse to icehouse climate transition. However, climate simulations and …

Documenting the Neotropical amphibian diversity has become a major challenge facing the
threat of global climate change and the pace of environmental alteration. Recent molecular …

Abstract The Atlantic rainforest of Brazil harbors outstanding species richness and levels of
endemism, representing one of the most biodiverse regions on Earth. Yet, a lot is still …
