Data from: Networks, trees, and treeshrews: assessing support and identifying conflict with multiple loci and a problematic root

Trina E. Roberts, Eric J. Sargis & Link E. Olson
Multiple unlinked genetic loci often provide a more comprehensive picture of evolutionary history than any single gene can, but analyzing multigene data presents particular challenges. Differing rates and patterns of nucleotide substitution, combined with the limited information available in any data set, can make it difficult to specify a model of evolution. In addition, conflict among loci can be the result of real differences in evolutionary process or of stochastic variance and errors in reconstruction....

Data from: Linked morphological changes during palate evolution in early tetrapods

Charles B. Kimmel, Brian Sidlauskas & Jennifer A. Clack
We examined the shapes and sizes of dermal bones of the palate of selected Palaeozoic tetrapods in order to identify the ancestral states of palatal bone morphologies in the earliest tetrapods, to learn how the composition of the palate varies within and among early tetrapod radiations, and recognize evolutionary correlations among the size and shapes of skeletal elements in this important group of animals. We find that whereas the palatal bones themselves and their arrangements...

Data from: Hunting to extinction: biology and regional economy influence extinction risk and the impact of hunting in artiodactyls

Samantha A. Price, John L. Gittleman, Samantha A Price & John L Gittleman
Half of all artiodactyls (even-toed hoofed mammals) are threatened with extinction, around double the mammalian average. Here, using a complete species-level phylogeny, we construct a multivariate model to assess for the first time which intrinsic (biological) and extrinsic (anthropogenic and environmental) factors influence variation in extinction risk in artiodactyls. Globally artiodactyls at greatest risk live in economically less developed areas, have older weaning ages and smaller geographical ranges. Our findings suggest that identifying predictors of...

Data from: The biogeography of introgression in the critically endangered African monkey Rungweceubs kipunji

Trina E. Roberts, Tim R. B. Davenport, Kyndall B. P. Hildebrandt, Trevor Jones, William T. Stanley, Eric J. Sargis & Link E. Olson
In the four years since its original description, the taxonomy of the kipunji (Rungwecebus kipunji), a geographically restricted and critically endangered African monkey, has been the subject of much debate, and recent research suggesting that the first voucher specimen of Rungwecebus has baboon mitochondrial DNA has intensified the controversy. We show that Rungwecebus from a second region of Tanzania has a distinct mitochondrial haplotype that is basal to a clade containing all Papio species and...
