The interacting effect of habitat amount, habitat diversity and fragmentation on insect diversity along elevational gradients.

Enric Frago, Niry T. Dianzinga, Marie-Ludders Moutoussamt, Joëlle Sadeyen & Lala Ravaomanarivo
Aim: Elevational gradients are a useful approach to evaluate how environmental factors affect animal diversity. Decades of studies on the elevation-diversity gradient have revealed that this gradient varies greatly with taxa and geographic regions. One potential explanation for this may be the dependence of the relationship on landscape features. We explore the impact of fragmentation, habitat diversity and habitat amount on insect diversity (alpha and beta) and abundance along elevational gradients. We hypothesize that insect...

Data from: Demographic history and genomic diversity and divergence in blue tit populations across heterogeneous environments

Charles Perrier, Quentin Rougemont & Anne Charmantier
Understanding the genomic processes underlying local adaptation is a central aim of modern evolutionary biology. This task requires identifying footprints of local selection but also estimating spatio-temporal variation in population demography and variation in recombination rate and diversity along the genome. Here, we investigated these parameters in blue tit populations inhabiting deciduous versus evergreen forests and insular versus mainland areas, in the context of a previously described strong phenotypic differentiation. Neighboring population pairs of deciduous...
