Amazonia Through Time: Andean Uplift, Climate Change, Landscape Evolution, and Biodiversity
It is shown that Andean uplift was crucial for the evolution of Amazonian landscapes and ecosystems, and that current biodiversity patterns are rooted deep in the pre-Quaternary.

It is shown that biotic migrations across the Isthmus of Panama began several million years earlier than commonly assumed, indicating that the dramatic biotic turnover associated with the Great American Biotic Interchange was a long and complex process that began as early as the Oligocene–Miocene transition.
raxmlGUI 2.0 beta: a graphical interface and toolkit for phylogenetic analyses using RAxML
RaxmlGUI 2.0-beta is presented, a complete rewrite of the GUI, which replaces raxml GUI and seamlessly integrates RAxML binaries for all major operating systems providing an intuitive graphical front-end to set up and run phylogenetic analyses.

Recent phylogenetic studies have revealed the major role played by the uplift of the Andes in the extraordinary diversification of the Neotropical flora. These studies, however, have typically…

The results suggest that multicellularity could have played a key role in triggering cyanobacterial evolution around the Great Oxidation Event, and an origin of cyanobacteria before the rise of atmospheric oxygen.
Amazonia is the primary source of Neotropical biodiversity

It is found that there has been extensive interchange of evolutionary lineages among different regions and biomes, over the course of tens of millions of years, and Amazonia stands out as the primary source of diversity, which can be mainly explained by the total amount of time Amazonian lineages have occupied the region.
Why are there so many plant species in the Neotropics
The evidence for each of these postulated causes of diversification is reviewed, the need of more well-sampled and dated phylogenies is highlighted, and increased inter-disciplinary collaboration is urged.
The abiotic and biotic drivers of rapid diversification in Andean bellflowers (Campanulaceae)

It is shown that speciation and extinction are differentially influenced by abiotic factors: speciation rates rose concurrently with Andean elevation, while extinction rates decreased during global cooling.

Comparison to the fossil record supports an early origin of multicellularity, possibly as early as the "Great Oxygenation Event" that occurred 2.45 - 2.22 billion years ago.
Molecular Studies and Phylogeography of Amazonian Tetrapods and their Relation to Geological and Climatic Models

It is concluded that a high proportion of present-day diversity is a result of Neogene diversifi cation, refuting the long-held hypothesis that repeated expansion and contraction of lowland forests during Pleistocene climatic changes would be responsible for most of the Amazonian biodiversity.
