Data from: The biogeography of Sulawesi revisited: is there evidence for a vicariant origin of taxa on Wallace’s “anomalous island”?

Björn Stelbrink, Christian Albrecht, Robert Hall & Thomas Von Rintelen
Sulawesi, the largest island in the Indonesian biodiversity hotspot region Wallacea, hosts a diverse endemic fauna whose origin has been debated for more than 150 years. We use a comparative approach based on dated phylogenies and geological constraints to test the role of vicariance versus dispersal in the origin of Sulawesi taxa. Most divergence time estimates for the split of Sulawesi lineages from their sister groups postdate relevant tectonic vicariant events, suggesting that the island...

Data from: Genome sequence of dwarf birch (Betula nana) and cross-species RAD markers

Nian Wang, Marian Thomson, William J. A. Bodles, Robert M. M. Crawford, Harriet V. Hunt, Alan Watson Featherstone, Jaume Pellicer & Richard J. A. Buggs
New sequencing technologies allow development of genome-wide markers for any genus of ecological interest, including plant genera such as Betula (birch) that have previously proved difficult to study due to widespread polyploidy and hybridisation. We present a de novo reference genome sequence assembly, from 67X short read coverage, of Betula nana (dwarf birch) – a diploid that is the keystone woody species of sub-arctic scrub communities but of conservation concern in Britain. We also present...

Data from: Experimental design in phylogenetics: testing predictions from expected information

Diego San Mauro, David J. Gower, James A. Cotton, Rafael Zardoya, Mark Wilkinson & Tim Massingham
Taxon and character sampling is central to phylogenetic experimental design yet we lack general rules. Goldman introduced a method to construct efficient sampling designs in phylogenetics, based on the calculation of expected Fisher information given a probabilistic model of sequence evolution. The considerable potential of this approach remains largely unexplored. In an earlier study, we applied Goldman’s method to a problem in the phylogenetics of caecilian amphibians and made an a priori evaluation and testable...

Data from: Year-round sexual harassment as a behavioral mediator of vertebrate population dynamics

Victoria Wearmouth, Emily Southall, David Morritt, Richard C. Thompson, Innes C. Cuthill, Julian Partridge, David W. Sims & Julian C. Partridge
Within-species sexual segregation is a widespread phenomenon among vertebrates but its causes remain a topic of much debate. Female avoidance of male coercive mating attempts has the potential to influence the social structure of animal populations, yet it has been largely overlooked as a driver of sexual separation. Indeed, its potential role in long-term structuring of natural populations has not been studied. Here we use a comparative approach to examine the suitability of multiple hypotheses...
