  • The mechanisms generating montane biodiversity remain incompletely understood. Here, the authors study the passerine avifauna of Indo-Pacific island mountains, finding that Eurasian-origin species colonized directly from other mountains, while Australo-Papuan-origin species made upslope range shifts from the lowlands.

  • Cilia are hair-like protuberances on the cellular surface that have been implicated in sensing and signal transduction. Here Gerdes et al. show cilia are involved in insulin signalling and secretion in pancreatic β-cells of rodents, and suggest that ciliary dysfunction could contribute to type 2 diabetes.

  • Hybrid zones are windows into the evolutionary process. Semenov et al. find that the head plumage differences between white wagtail subspecies have a simple genetic basis involving two small genetic regions, in which partially dominant and epistatic interactions help to explain how this sexual signal has become decoupled from other plumage traits.

  • Hume’s ground tit (Parus humilis) was once thought to belong to the Corvidae family, which includes crows and jays. Qu et al.sequence and analyse Hume's ground tit genome, as well as two additional tits and a ground jay, and establish its evolutionary position as the world's largest tit.

  • In Himalayan songbirds, the speciation rate is ultimately set by ecological competition, rather than by the rate of acquisition of reproductive isolation.
