Comparative genomic studies are revealing that, in sharp contrast with the strong stability found in birds and mammals, sex determination mechanisms are surprisingly labile in cold-blooded vertebrates, with frequent transitions between different pairs of sex chromosomes. It was recently suggested that, in context of this high turnover, some chromosome pairs might be more likely than others to be co-opted as sex chromosomes. Empirical support, however, is still very limited. Here we show that sex-linked markers...

Data from: Conservation phylogeography: does historical diversity contribute to regional vulnerability in European tree frogs (Hyla arborea)

Documenting and preserving the genetic diversity of populations, which conditions their long-term survival, has become a major issue in conservation biology. The loss of diversity often documented in declining populations is usually assumed to result from human disturbances; however, historical biogeographic events, otherwise known to strongly impact diversity, are rarely considered in this context. We apply a multi-locus phylogeographic study to investigate the late-Quaternary history of a tree frog (Hyla arborea) with declining populations in...
