Data from: The role of continental shelf width in determining freshwater phylogeographic patterns in southeastern Australian pygmy perches (Teleostei: Percichthyidae)

Peter J. Unmack, Michael P. Hammer, Mark Adams, Jerald B. Johnson & Thomas E. Dowling
Biogeographic patterns displayed by obligate freshwater organisms are intimately related to the nature and extent of connectivity between suitable habitats. Two of the more significant barriers to freshwater connections are seawater and major drainage divides. South-eastern Australia provides a contrast between these barriers as it has discrete areas that are likely influenced to a greater or lesser extent by each barrier type. We use continental shelf width as a proxy for the potential degree of...

Data from: Are shy individuals less behaviorally variable? Insights from a captive population of mouse lemurs

Jennifer L. Verdolin & John Harper
Increasingly, individual variation in personality has become a focus of behavioral research in animal systems. Boldness and shyness, often quantified as the tendency to explore novel situations, are seen as personality traits important to the fitness landscape of individuals. Here we tested for individual differences within and across contexts in behavioral responses of captive mouse lemurs (Microcebus murinus) to novel objects, novel foods, and handling. We report consistent differences in behavioral responses for objects and...

Data from: Marine-freshwater transitions are associated with the evolution of dietary diversification in terapontid grunters (Teleostei: Terapontidae)

Aaron M. Davis, Peter J. Unmack, Bradley J. Pusey, Richard G. Pearson & Jerry B. Johnson
The ecological opportunities associated with transitions across the marine-freshwater interface are regarded as an important catalyst of diversification in a range of aquatic taxa. Here, we examined the role of these major habitat transitions and trophic diversification in a radiation of Australasian fishes using a new molecular phylogeny incorporating 37 Terapontidae species. A combined mitochondrial and nuclear gene analysis yielded a well supported tree with most nodes resolved. Ancestral terapontids appear to have been euryhaline...

Data from: Convergent evolution of phenotypic integration and its alignment with morphological diversification in Carribean Anolis ecomorphs

Jason J. Kolbe, Liam J. Revell, Brian Szekely, & Jonathan B Losos
The adaptive landscape and the G-matrix are keys concepts for understanding how quantitative characters evolve during adaptive radiation. In particular, whether the adaptive landscape can drive convergence of phenotypic integration (i.e., the pattern of phenotypic variation and covariation summarized in the P-matrix) is not well studied. We estimated and compared P for 19 morphological traits in eight species of Caribbean Anolis lizards, finding that similarity in P among species was not correlated with phylogenetic distance....

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...

Data from: Data archiving is a good investment

Heather A. Piwowar, Todd J. Vision & Michael C. Whitlock
Funding agencies are reluctant to support data archiving, even though large research funders such as the National Science Foundation (NSF) and the National Institutes of Health acknowledge its importance for scientific progress. Our quantitative estimates of data reuse indicate that ongoing financial investment in data-archiving infrastructure provides a high scientific return.
