A comprehensive phylogeny of birds (Aves) using targeted next-generation DNA sequencing
TLDR
The results of the divergence time analyses are congruent with the palaeontological record, supporting a major radiation of crown birds in the wake of the Cretaceous–Palaeogene (K–Pg) mass extinction.
Profiling phylogenetic informativeness.
TLDR
This measure of phylogenetic informativeness provides a quantitative measure of the capacity of a gene to resolve soft polytomies and conveys the utility of the addition of characters a phylogenetic study and provides a basis for deciding whether appropriate phylogenetic power has been applied to a polytomy that is proposed to be a rapid radiation.

Horizontal gene transfer, genome innovation and evolution
TLDR
It is suggested that for many prokaryotes, the boundaries between species are fuzzy, and therefore the principles of population genetics must be broadened so that they can be applied to higher taxonomic categories.
Phylogenetic and phylogenomic overview of the Polyporales
TLDR
The most promising candidate single-copy genes are presented, and nodes in the Polyporales phylogeny critical for the suprageneric taxonomy of the order are identified and discussed.
The Ascomycota tree of life: a phylum-wide phylogeny clarifies the origin and evolution of fundamental reproductive and ecological traits.
TLDR
A 6-gene, 420-species maximum-likelihood phylogeny of Ascomycota, the largest phylum of Fungi, and a phylogenetic informativeness analysis of all 6 genes and a series of ancestral character state reconstructions support a terrestrial, saprobic ecology as ancestral are presented.
Bayesian analysis of gene expression levels: statistical quantification of relative mRNA level across multiple strains or treatments
TLDR
Anyone with replicated normalized cDNA microarray ratio datasets can use the freely available MacOS and Windows software, which yields increased biological insight by taking advantage of replication to discern important changes in expression level both above and below a twofold threshold.
Eukaryotic microbes, species recognition and the geographic limits of species: examples from the kingdom Fungi
TLDR
It is shown that inferred geographic range of a fungal species depends upon the method of species recognition and that microbial organisms generally have fewer morphological characters, and that the rate of morphological change will be slower for organisms with less elaborate development and fewer cells.
Strategies for containing Ebola in West Africa
TLDR
It is found that a combined approach of case isolation, contact-tracing with quarantine, and sanitary funeral practices must be implemented with utmost urgency in order to reverse the growth of the outbreak of Ebola.
Population structure and gene evolution in Saccharomyces cerevisiae.
TLDR
This is the first multilocus sequence study of population structure in natural isolates of S. cerevisiae, and the first study to detect historical selection on a locus important to the natural history of wine yeast.
