Seddon N, Botero CA, Tobias JA, Dunn PO, Macgregor HE, Rubenstein DR, Uy JA, Weir JT, Whittingham LA, Safran RJet al., 2013, Sexual selection accelerates signal evolution during speciation in birds, Proceedings of the Royal Society B: Biological Sciences, Vol: 280, ISSN: 0962-8452

Sexual selection is proposed to be an important driver of diversification in animal systems, yet previous tests of this hypothesis have produced mixed results and the mechanisms involved remain unclear. Here, we use a novel phylogenetic approach to assess the influence of sexual selection on patterns of evolutionary change during 84 recent speciation events across 23 passerine bird families. We show that elevated levels of sexual selection are associated with more rapid phenotypic divergence between related lineages, and that this effect is restricted to male plumage traits proposed to function in mate choice and species recognition. Conversely, we found no evidence that sexual selection promoted divergence in female plumage traits, or in male traits related to foraging and locomotion. These results provide strong evidence that female choice and male-male competition are dominant mechanisms driving divergence during speciation in birds, potentially linking sexual selection to the accelerated evolution of pre-mating reproductive isolation.

Tobias JA, Şekercioǧlu CH, Vargas HF, 2013, Bird conservation in tropical ecosystems: challenges and opportunities, Key Topics in Conservation Biology 2, Pages: 258-276, ISBN: 9780470658765

Bird conservation is a global mission but most of the key battles are being played out in the tropics. This chapter summarizes the key attributes of tropical ecosystems and implications for bird conservation. First, it outlines threats to key tropical environments. Then it argues that tropical species often differ from their temperate-zone counterparts in ways that pose novel challenges for conservation. The chapter concludes that sustainable conservation of tropical birds and the ecosystem services they provide will be achieved only if attention is focused on biotic processes and interactions operating at larger spatial and temporal scales. The strategies proposed by the authors have broad relevance for the management of tropical diversity because birds have long been viewed as a model system for assessing conservation priorities, and act as flagships for numerous conservation programmes. © 2013 John Wiley & Sons, Ltd.

© The Neotropical Ornithological Society. Suboscine passerine birds are one of the most prominent components of Neotropical avifaunas, yet they remain relatively poorly studied in comparison with their sister-clade, the oscine passerines. This situation appears to be changing rapidly as more ornithologists realize that suboscine birds offer ideal study systems for investigating a variety of research questions. We summarise a symposium focused on studies of tracheophone suboscines (woodcreepers, ovenbirds, antbirds and allies) and highlight recent advances in our understanding of their history and behavior. We argue that because of their antiquity and high levels of diversity, they make excellent subjects for comparative analyses and phylogenetic models. Moreover, several details of their breeding and signaling systems predispose them to field-based observational and experimental studies of social interactions and signal evolution, as well as automated techniques for vocal recognition. We discuss potential new avenues of research on suboscine passerines, and conclude that they are likely to play an increasingly important role as study systems in tropical ecology and evolutionary biology.
