Data from: Extending ecological niche models to the past 120 000 years corroborates the lack of strong phylogeographic structure in the Crested Drongo (Dicrurus forficatus forficatus) on Madagascar

Jérôme Fuchs, Juan L. Parra, Steven M. Goodman, Marie Jeanne Raherilalao, Jeremy Vanderwal & Rauri C. K. Bowie
We conduct a phylogeographic study of the Crested Drongo (Dicrurus forficatus forficatus), a broadly distributed bird species on Madagascar. We first determined the demographic and spatial pattern inferred from mitochondrial and nuclear data, and then compared these results with predictions from a present to 0.120-Myr-old reconstruction of the spatial dynamics of the range of D. f. forficatus on Madagascar, enabling putative areas of stability (lineage persistence) to be detected. Weak genetic structure along an east–west...

Data from: The influence of fledgling location on adult provisioning: a test of the blackmail hypothesis

Alex M. Thompson, Nichola J. Raihani, Philip A. R. Hockey, Adam Britton, Fiona M. Finch & Amanda R. Ridley
One theory to explain the existence of conspicuous solicitation is that it is a way for young to ‘blackmail’ care-givers into provisioning them, by threatening their own destruction. Fledgling birds offer a unique opportunity to investigate the ‘blackmail theory’, as their mobility enables them to influence the predation risk they face. We investigated a novel solicitation behaviour in fledgling pied babblers (Turdoides bicolor), where fledglings use their location to influence provisioning rates. We show that...

Data from: Constructing phylogenies in the presence of Intra-Individual Site Polymorphisms (2ISPs) with a focus on the nuclear ribosomal cistron

Alastair J. Potts, Terry A. Hedderson & Guido W. Grimm
Nuclear DNA is widely used to estimate phylogenetic and phylogeographic relationships. Nuclear gene variants may be present in an individual's genome, and these result in Intra-Individual Site Polymorphisms (2ISP; pronounced 'twisp') in direct-PCR or individual-consensus sequences based on a clone sample. 2ISPs can occur fairly often, especially within, but not restricted to, high-copy-number regions such as the widely used internal transcribed spacers of the nuclear ribosomal cistron. Dealing with 2ISPs has been problematic as phylogeny...
