Amazonia Through Time: Andean Uplift, Climate Change, Landscape Evolution, and Biodiversity
TLDR
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.
Biological evidence supports an early and complex emergence of the Isthmus of Panama
TLDR
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.
Tracing the impact of the Andean uplift on Neotropical plant evolution
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
raxmlGUI 2.0: a graphical interface and toolkit for phylogenetic analyses using RAxML
TLDR
RaxmlGUI 2.0, a complete rewrite of the GUI which seamlessly integrates RAxML binaries for all major operating systems with an intuitive graphical front-end to set up and run phylogenetic analyses, is presented.
Evolution of multicellularity coincided with increased diversification of cyanobacteria and the Great Oxidation Event
TLDR
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.
Why are there so many plant species in the Neotropics
TLDR
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.
Molecular Studies and Phylogeography of Amazonian Tetrapods and their Relation to Geological and Climatic Models
TLDR
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.
Higher level phylogeny and evolutionary trends in Campanulaceae subfam. Lobelioideae: molecular signal overshadows morphology.

  • 2008
TLDR
Results derived from Bayesian and parsimony analyses provide evidence for the long-suspected paraphyly of the genus Lobelia, and character optimizations on the phylogenetic tree reveal that shifts in fruit types and lignification have occurred much more commonly than generally assumed.
The abiotic and biotic drivers of rapid diversification in Andean bellflowers (Campanulaceae)
TLDR
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.
The origin of multicellularity in cyanobacteria
TLDR
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.
