Diversification of Amazonian spiny tree rats in genus Makalata (Rodentia, Echimyidae): Cryptic diversity, geographic structure and drivers of speciation.
Amazonian mammal diversity is exceptionally high, yet new taxonomic discoveries continue to be made and many questions remain for understanding its diversification through time and space. Here we investigate the diversification of spiny rats in the genus , whose species are strongly associated with seasonally flooded forests, watercourses and flooded... -

Diversification dynamics in the Neotropics through time, clades, and biogeographic regions.
The origins and evolution of the outstanding Neotropical biodiversity are a matter of intense debate. A comprehensive understanding is hindered by the lack of deep-time comparative data across wide phylogenetic and ecological contexts. Here, we quantify the prevailing diversification trajectories and drivers of Neotropical diversification in a sample of 150... -

Global variation in diversification rate and species richness are unlinked in plants.
Species richness varies immensely around the world. Variation in the rate of diversification (speciation minus extinction) is often hypothesized to explain this pattern, while alternative explanations invoke time or ecological carrying capacities as drivers. Focusing on seed plants, the world’s most important engineers of terrestrial ecosystems, we investigated the role...Tietje, Melanie ; Antonelli, Alexandre ; Baker, William J. ; Govaerts, Rafaël ; Smith, Stephen A. …

Hybridization: a ‘double-edged sword’ for Neotropical plant diversity.
Hybridization can facilitate both evolutionary diversification and extinction and has had a critical role in plant evolution, with c. 25% of species known to hybridize in some temperate floras. However, in the species-rich Neotropical flora, the role of hybridization in the evolution of diversity remains unclear. Our review examines studies...Schley, Rowan J ; Twyford, Alex D ; Pennington, R Toby

Disproportionate extinction of South American mammals drove the asymmetry of the Great American Biotic Interchange.
The interchange between the previously disconnected faunas of North and South America was a massive experiment in biological invasion. A major gap in our understanding of this invasion is why there was a drastic increase in the proportion of mammals of North American origin found in South America. Four nonmutually...
