The capercaillie inhabits a continuous range in large parts of the Palearctic boreal forest, but
is patchily distributed in temperate Europe. An ongoing population decline, largely related to …

Population bottlenecks can restrict variation at functional genes, reducing the ability of
populations to adapt to new and changing environments. Understanding how populations …

Selection on allozymes has sometimes been advanced as one explanation for the low levels
of population differentiation detected in avian populations by the use of enzymatic markers …

Divergent selection stemming from environmental variation may induce local adaptation and
ecological speciation whereas gene flow might have a homogenizing effect. Gene flow …

Due to a lack of distinctive morphological characters, swift taxonomy and phylogeny has
always been an area of disagreement. To shed more light on this subject, we reconstructed …

Background Adaptive divergence between populations in the face of strong selection on key
traits can lead to morphological divergence between populations without concomitant …

Habitat fragmentation is one of the most severe threats to biodiversity as it may lead to
changes in population genetic structure, with ultimate modifications of species evolutionary …

Divergent selection and local adaptation are responsible for many phenotypic differences
between populations, potentially leading to speciation through the evolution of reproductive …

Mobile organisms are expected to show population differentiation only over fairly large
geographical distances. However, there is growing evidence of discrepancy between …

The relative influences of history, natural selection and hybridization in shaping phenotypic
variation in closely related taxa is a crucial issue in current evolutionary biology. In this …
