Diversity, Endemism, and Evolutionary History of Montane Biotas Outside the Andean Region
Mountain ranges are important centers of biodiversity around the world. This high diversity is the result of the presence of different soil types and underlying bedrock, a variety of micro-climatic regimes, high topographic heterogeneity, a heterogeneous and complex vegetation cline, and a dynamic geo-climatic history. Neotropical research on mountains has... -

Extensive plastid-nuclear discordance in a recent radiation of Nicotiana section Suaveolentes (Solanaceae)
Nicotiana section Suaveolentes is the largest section of Nicotiana and is a monophyletic group of allotetraploid species. Most of the species are endemic to Australia, but three species occur on islands in the South Pacific as far east as French Polynesia and one species is native to Namibia. Here, we... -

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... -

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

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. …

A Taxonomic Revision of Styppeiochloa (Arundinoideae: Poaceae) in Madagascar.
The grass genus Styppeiochloa De Winter (Arundinoideae: Poaceae) as it occurs in Madagascar is reviewed, two new species are described, and two subspecific taxa are elevated to species status. These new species, as well as the additional collections made since the latest treatment of the genus for Madagascar in 1954,... -

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... -

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... -
