Data from: Phylogeography of Aegean green toads (Bufo viridis subgroup): continental hybrid swarm vs. insular diversification with discovery of a new island endemic

Christophe Dufresnes, Petros Lymberakis, Panagiotis Kornilios, Romain Savary, Nicoals Perrin & Matthias Stöck
Background: Debated aspects in speciation research concern the amount of gene flow between incipient species under secondary contact and the modes by which post-zygotic isolation accumulates. Secondary contact zones of allopatric lineages, involving varying levels of divergence, provide natural settings for comparative studies, for which the Aegean (Eastern Mediterranean) geography offers unique scenarios. In Palearctic green toads (Bufo viridis subgroup or Bufotes), Plio-Pleistocene (~2.6 Mya) diverged species show a sharp transition without contemporary gene flow,...

Data from: Genome-wide markers untangle the green-lizard radiation in the Aegean Sea and support a rare biogeographical pattern

Panagiotis Kornilios, Evanthia Thanou, Petros Lymberakis, Çetin Ilgaz, Yusuf Kumlutaş & Adam Leache
Aim: The Aegean Sea constitutes a major biogeographic barrier between the European and Asian continents and several models of diversification in the Aegean have been documented. Here we test three of those models for the Aegean green-lizards (Lacerta trilineata–pamphylica group): Vicariance vs. Overland Dispersal vs. Island Stepping-stone Dispersal. We investigate these hypotheses and complement our knowledge on the impact of the Aegean Barrier on east Mediterranean taxa. Location: Aegean Sea, east Mediterranean Taxon: Lacerta lizards...

Data from: Fitness costs of key point mutations that underlie acaricide target-site resistance in the two-spotted spider mite Tetranychus urticae

The frequency of insecticide/acaricide target-site resistance is increasing in arthropod pest populations and is typically underpinned by single point mutations that affect the binding strength between the insecticide/acaricide and its target-site. Theory predicts that although resistance mutations clearly have advantageous effects under the selection pressure of the insecticide/acaricide, they might convey negative pleiotropic effects on other aspects of fitness. If such fitness costs are in place, target-site resistance is thus likely to disappear in the...

Data from: Selection, drift and introgression shape MHC polymorphism in lizards

The Major Histocompatibility Complex (MHC) has long served as a model for the evolution of adaptive genetic diversity in wild populations. Pathogen-mediated selection is thought to be a main driver of MHC diversity, but it remains elusive to what degree selection shapes MHC diversity in complex biogeographical scenarios where other evolutionary processes (e.g. genetic drift and introgression) may also be acting. Here, we focus on two closely related green lizard species, Lacerta trilineata and L....
