A meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project is presented, creating both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth’s microbial diversity.

Biogeographic analyses revealed the importance of the Neotropics in noctilionoid diversification, and the critical role of dispersal, and simulations modeling constant speciation and extinction rates for the phylogeny systematically showed more speciation events in the Quaternary.

Results show that a novel stenodermatine skull phenotype played a central role in the evolution of frugivory and increasing speciation within phyllostomids, with a significant increase in diversification rate driven by increased speciation at the most recent common ancestor.

A review of the taxonomy, distribution and phylogeny of all Cenozoic Caribbean non-volant mammals and four bat lineages and present reconciled trees for available phylogenies finds patterns of divergence from the mainland that are inconsistent with the Gaarlandia hypothesis and seem to require taxon-specific biogeographical explanations.
The geography of diversification in the mormoopids (Chiroptera: Mormoopidae)

Analysis of sequence data from the mitochondrial 12S, tRNAval, 16S, and cytochrome b, and the nuclear Rag2, to evaluate species boundaries and infer relationships among extant taxa suggests that mormoopids diversified in northern Neotropics before entering South America.
Exploring population genetic structure in three species of Lesser Antillean bats

A conservative interpretation of the molecular data is that island populations of Artibeus jamaicensis, although isolated geographically, are not isolated genetically, and simulations of gene trees within a population tree suggest that lineage sorting is an unlikely explanation for the observed pattern of nonmonophyly.
Phylogeny and Divergence Times of Lemurs Inferred with Recent and Ancient Fossils in the Tree.

This is the first study to combine morphological and DNA sequence data from extinct and extant primates to infer evolutionary relationships and divergence times, and the results shed new light on the tempo of lemur evolution and the efficacy of combined phylogenetic analyses.
The San Lucas mountain range in Colombia: how much conservation is owed to the violence?

The imminence of forest conversion in the northern Andean region requires a careful evaluation of the social, political and economic context in which environmental efforts take place in order to…
The Nature and Dynamics of Bacterial Genomes

This work estimates that this genome harbors hundreds of inactivated and otherwise functionless genes that will never yield a detectable phenotype, but are vital to efforts to elucidate the biological role of all the proteins within the cell.
