Genetic diversity, differentiation and historical origin of the isolated population of rooksCorvus frugilegusin Iberia

Pablo Salinas, Francisco Morinha, Ivan Literak, Javier García, Borja Milá & Guillermo Blanco
Current bird populations in southern temperate latitudes often represent relicts of glacial refugia from which northern populations expanded as the climate became suitable following the last glacial maximum, 18 000 years before present. Alternatively, these southern populations could be the result of the fragmentation of large distributions and other processes not related to glaciations, like recent recolonization from northern populations and human impact in historical times. Here, we investigate the origin of a small, isolated...

Salomão, Leandro Valle Ferreira, Dário Dantas Do Amaral, Nigel C.A. Pitman, Corine Vriesendorp, Tim R. Baker, Roel Brienen, Marcelo De Jesus Veiga Carim … & Flávia R.C. Costa
Tree diversity and composition in Amazonia are known to be strongly determined by the water supplied by precipitation. Nevertheless, within the same climatic regime, water availability is modulated by local topography and soil characteristics (hereafter referred to as local hydrological conditions), varying from saturated and poorly drained to well-drained and potentially dry areas. While these conditions may be expected to influence species distribution, the impacts of local hydrological conditions on tree diversity and composition remain...

Data from: On the specificity of avian blood parasites: revealing specific and generalist relationships between haemosporidians and biting midges

Josué Martínez-De La Puente, Javier Martínez, Juan Rivero-De Aguilar, Jessica Herrero & Santiago Merino
The study of host-parasite relationships involving vector-borne parasites requires understanding interactions between parasites and vectors. The capacity of haemosporidians to infect insects has clear evolutionary consequences for the transmission of diseases. Here we investigated (1) the associations between blood parasites, biting midges and birds and (2) the potential specificity between biting midge and haemosporidian haplotypes. A total of 629 parous biting midges Culicoides and 224 wild birds (belonging to seven species) from a locality of...

Data from: Candidate genes for colour and vision exhibit signals of selection across the pied flycatcher (Ficedula hypoleuca) breeding range

Paula K. Lehtonen, Toni Laaksonen, Aleksandr V. Artemyev, Eugen Belskii, Paul R. Berg, Christiaan Both, Laura Buggiotti, Stanislav Bureš, Malcolm D. Burgess, Andrey V. Bushuev, Indrikis Krams, Juan Moreno, Marko Mägi, Andreas Nord, Jaime Potti, Pierre-Alain Ravussin, Glenn Peter Sætre, Paivi Sirkiä, Wolfgang Winkel & Craig R. Primmer
The role of natural selection in shaping adaptive trait differentiation in natural populations has long been recognized. Determining its molecular basis, however, remains a challenge. Here, we search for signals of selection in candidate genes for colour and its perception in a passerine bird. Pied flycatcher plumage varies geographically in both its structural and pigment-based properties. Both characteristics appear to be shaped by selection. A single-locus outlier test revealed two of fourteen loci to exhibit...

Data from: Population divergence in chemical signals and the potential for premating isolation between islet- and mainland populations of the Skyros wall lizard, (Podarcis gaigeae)

Anna Runemark, Marianne Gabirot & Erik I Svensson
When sexually selected traits diverge due to different local selective environments premating isolation might arise as a correlated response. However, sexually selected traits might also diverge by stochastic forces. Here, we show that odour-based mate preferences and scent composition have diverged between islet- and mainland populations of Skyros wall lizard, Podarcis gaigeae. We quantified the degree of scent-mediated premating isolation between populations. Islet lizards preferred scent from islet lizards, whereas the mainland populations were less...

Data from: Hybrid origin of Audubon's warbler

Alan Brelsford, Borja Milá & Darren E Irwin
Several animal species have recently been shown to have hybrid origins, but no avian examples have been documented with molecular evidence. We investigate whether the Audubon's warbler, one of four visually distinct species in the yellow-rumped warbler (Dendroica coronata) complex, may have originated through hybridization between two other species in this group, the myrtle warbler and black-fronted warbler. Analysis of nuclear AFLP and sequence markers shows that Audubon's warblers are genetically intermediate, and carry a...

Data from: Reversal to air-driven sound production revealed by a molecular phylogeny of tongueless frogs, family Pipidae

Iker Irisarri, Miguel Vences, Diego San Mauro, Frank Glaw & Rafael Zardoya
BACKGROUND: Evolutionary novelties often appear by conferring completely new functions to pre- existing structures or by innovating the mechanism through which a particular function is performed. Sound production plays a central role in the behavior of frogs, which use their calls to delimit territories and attract mates. Therefore, frogs have evolved complex vocal structures capable of producing a wide variety of advertising sounds. It is generally acknowledged that most frogs call by moving an air...

Data from: Bayesian analysis of hybridization and introgression between the endangered european mink (Mustela lutreola) and the polecat (Mustela putorius)

Maria Teresa Cabria, Johan R Michaux, Benjamín J Gómez-Moliner, Dimitry Skumatov, Tiit Maran, Pascal Fournier, Javier López De Luzuriaga & Rafael Zardoya
Human-mediated global change will probably increase the rates of natural hybridization and genetic introgression between closely related species, and this will have major implications for conservation of the taxa involved. In this study, we analyse both mitochondrial and nuclear data to characterize ongoing hybridization and genetic introgression between two sympatric sister species of mustelids, the endangered European mink (Mustela lutreola) and the more abundant polecat (M. putorius). A total of 317 European mink, 114 polecats...

Data from: Major histocompatability complex variation in insular populations of the Egyptian vulture: inferences about the roles of genetic drift and selection

Rosa Agudo, Miguel Alcaide, Ciro Rico, Jesus Angel Lemus, Guillermo Blanco, Fernando Hiraldo & Jose Antonio Donázar
Insular populations have attracted the attention of evolutionary biologists because of their morphological and ecological peculiarities with respect to their mainland counterparts. Founder effects and genetic drift are known to distribute neutral genetic variability in these demes. However, elucidating whether these evolutionary forces have also shaped adaptive variation is crucial to evaluate the real impact of reduced genetic variation in small populations. Genes of the Major Histocompatibility Complex (MHC) are classical examples of evolutionarily relevant...

Data from: Molecular phylogeny and biogeography of Malagasy frogs of the genus Gephyromantis

Nathalie Kaffenberger, Katharina C. Wollenberg, Jörn Köhler, Frank Glaw, David R. Vieites & Miguel Vences
The genus Gephyromantis is a clade within the Malagasy–Comoroan family Mantellidae composed of rainforest frogs that live and breed to varying degrees independently from water. Based on DNA sequences of five mitochondrial and five nuclear genes we inferred the phylogeny of these frogs with full taxon coverage at the species level. Our preferred consensus tree from a partitioned Bayesian analysis of 5843 base pairs of 51 nominal and candidate species supports various major clades within...
