Data from: Nest size and aromatic plants in the nest as sexually selected female traits in blue titsGustavo Tomás, Santiago Merino, Josué Martínez-De La Puente, Juan Moreno, Judith Morales & Juan Rivero-De Aguilar
Besides the direct functionality of nests driven by natural selection, accumulating evidence shows that nest building behaviors and nests may also evolve under sexual selection. Empirical research on the potential role of nests or nest features as sexual signals, however, is comparatively scarce for avian species in which the female is the only sex involved in its construction because of a male bias in the study of sexual traits, even though maternally built nests may...
The genetic covariation among different traits may cause the appearance of correlated response to selection on multivariate phenotypes. Genes responsible for the expression of melanin-based color traits are also involved in other important physiological functions such as immunity and metabolism by pleiotropy, suggesting the possibility of multivariate evolution. However, little is known about the relationship between melanin coloration and these functions at the additive genetic level in wild vertebrates. From a multivariate perspective, we simultaneously...
Spiny-backed tree frogs of the genus Osteocephalus are conspicuous components of the tropical wet forests of the Amazon and the Guiana Shield. Here, we revise the phylogenetic relationships of Osteocephalus and its sister group Tepuihyla, using up to 6134 bp of DNA sequences of nine mitochondrial and one nuclear gene for 338 specimens from eight countries and 218 localities, representing 89% of the 28 currently recognized nominal species. Our phylogenetic analyses reveal (i) the paraphyly...
The mammalian fossil record of Spain is long and taxonomically well resolved, offering the most complete record of faunal change for the Neogene of Europe. We evaluated changes in diversification, composition, trophic structure, and size structure of large mammals over the middle and late Miocene with methods applied to this record for the first time, including ordination of fossil localities to improve temporal resolution and estimation of confidence intervals on taxa temporal ranges. By contrast,...
Gobioidei is one of the largest suborders of teleost fishes, with nearly 2000 extant species currently recognized. They have a worldwide distribution and show a spectacular variety in morphology, ecology, and behavior. Despite their importance, phylogenetic relationships among many groups of gobioids (including some of the major lineages) still remain poorly understood. In this study, we analyze sequence data of five molecular markers (two mitochondrial and three nuclear) averaging 6000 bp for 222 species of...
Data from: Mass production of SNP markers in a nonmodel passerine bird through RAD sequencing and contig mapping to the zebra finch genomeYann X. C. Bourgeois, Emeline Lhuillier, Timothée Cézard, Joris A. M. Bertrand, Boris Delahaie, Josselin Cornuault, Thomas Duval, Olivier Bouchez, Borja Milá & Christophe Thébaud
Here, we present an adaptation of restriction-site-associated DNA sequencing (RAD-seq) to the Illumina HiSeq2000 technology that we used to produce SNP markers in very large quantities at low cost per unit in the Réunion grey white-eye (Zosterops borbonicus), a nonmodel passerine bird species with no reference genome. We sequenced a set of six pools of 18–25 individuals using a single sequencing lane. This allowed us to build around 600 000 contigs, among which at least...
