Data from: XY females do better than the XX in the African pygmy mouse, Mus minutoides

Paul Alan Saunders, Julie Perez, Massilva Rahmoun, Ophelie Ronce, Pierre-André Crochet & Frédéric Veyrunes
All therian mammals have a similar XY/XX sex determination system except for a dozen species. The African pygmy mouse, Mus minutoides, harbors an unconventional system in which all males are XY, and there are three types of females: the usual XX but also XX* and X*Y ones (the asterisk designates a sex reversal mutation on the X chromosome). The long-term evolution of such a system is a paradox, since X*Y females are expected to face...

Data from: Convergent and correlated evolution of major life-history traits in the angiosperm genus Leucadendron (Proteaceae)

Natural selection is expected to cause convergence of life histories among taxa as well as correlated evolution of different life-history traits. Here, we quantify the extent of convergence of five key life-history traits (adult fire survival, seed storage, degree of sexual dimorphism, pollination mode, and seed-dispersal mode) and test hypotheses about their correlated evolution in the genus Leucadendron (Proteaceae) from the fire-prone South African fynbos. We reconstructed a new molecular phylogeny of this highly diverse...

Data from: Mating systems and selection efficacy: a test using chloroplastic sequence data in Angiosperms

Sylvain Glémin & Aline Muyle
Selfing is assumed to reduce selection efficacy, especially purifying selection. This can be tested using molecular data, for example by comparing the Dn/Ds ratio between selfing and outcrossing lineages. So far, little evidence of relaxed selection against weakly deleterious mutations (as inferred by a higher Dn/Ds ratio) in selfers as compared to outcrossers has been found, contrary to the pattern often observed between asexual and sexual lineages. However, few groups have been studied to date....

Data from: Spatial heterogeneity in the Mediterranean Biodiversity Hotspot affects barcoding accuracy of its freshwater fishes

B. Delmastro
Incomplete knowledge of biodiversity remains a stumbling block for conservation planning, and even occurs within globally important Biodiversity Hotspots. Although technical advances have boosted the power of molecular biodiversity assessments, the link between DNA sequences and species and the analytics to discriminate entities, remain crucial. Here, we present an analysis of the first DNA barcode library for the freshwater fish fauna of the Mediterranean Biodiversity Hotspot (526 spp.), with virtually complete species coverage (498 spp.,...
