Data from: Phylogenetic relationships of Trachylepis skink species from Madagascar and the Seychelles (Squamata: Scincidae)

Alexandra Lima, David James Harris, Sara Rocha, Aurélien Miralles, Frank Glaw & Miguel Vences
Lizards of the genus Trachylepis are a species-rich group of skinks mainly inhabiting Africa, Madagascar, and several other islands in the western Indian Ocean. All except one probably introduced species of Madagascan Trachylepis are endemic. Two species groups have been distinguished on the basis of subocular scale shape but their phylogenetic relationships remained unclear. We inferred a multilocus phylogeny of the Madagascan Trachylepis species, based on a concatenated dataset of 3261 bp from 3 mitochondrial...

Data from: Identifying loci under selection against gene flow in isolation with migration models

Vitor C. Sousa, Miguel Carneiro, Nuno Ferrand & Jody Hey
When divergence occurs in the presence of gene flow, there can arise an interesting dynamic in which selection against gene flow, at sites associated with population-specific adaptations or genetic incompatibilities, can cause net gene flow to vary across the genome. Loci linked to sites under selection may experience reduced gene flow and may experience genetic bottlenecks by the action of nearby selective sweeps. Data from histories such as these may be poorly fitted by conventional...

Data from: Home loving boreal hare mitochondria survived several invasions in Iberia: the relative roles of recurrent hybridisation and allele surfing

José Melo-Ferreira, Liliana Farelo, Helder Freitas, Franz Suchentrunk, Pierre Boursot & Paulo C. Alves
Genetic introgression from a resident species into an invading close relative can result from repeated hybridisation along the invasion front and/or allele surfing on the expansion wave. Cases where the phenomenon is massive and systematic, such as for hares (genus Lepus) in Iberia, would be best explained by recurrent hybridisation but this is difficult to prove since the donor populations are generally extinct. In the Pyrenean foothills, Lepus europaeus presumably replaced Lepus granatensis recently and...

Data from: Validating the use of coloration patterns for individual recognition in the worm pipefish using a novel set of microsatellite markers

Nuno M. Monteiro, Rodolfo M. Silva, Mário Cunha, Agostinho Antunes, Adam G. Jones & Maria N. Vieira
In studies of behaviour, ecology and evolution, identification of individual organisms can be an invaluable tool, capable of unravelling otherwise cryptic information regarding group structure, movement patterns, population size and mating strategies. The use of natural markings is arguably the least invasive method for identification. However, to be truly useful natural markings must be sufficiently variable to allow for unique identification, while being stable enough to permit long-term studies. Non-invasive marking techniques are especially important...

Data from: Steep clines within a highly permeable genome across a hybrid zone between two subspecies of the European rabbit

Miguel Carneiro, Stuart J. E. Baird, Sandra Afonso, Esther Ramirez, Pedro Tarroso, Henrique Teotonio, Rafael Villafuerte, Michael W. Nachman & Nuno Ferrand
Maintenance of genetic distinction in the face of gene flow is an important aspect of the speciation process. Here, we provide a detailed spatial and genetic characterization of a hybrid zone between two subspecies of the European rabbit. We examined patterns of allele frequency change for 22 markers located on the autosomes, X-chromosome, Y-chromosome, and mtDNA in 1078 individuals sampled across the hybrid zone. While some loci revealed extremely wide clines (w>=300 km) relative to...
