Effective population size, Ne, is a key evolutionary parameter that determines the levels of
genetic variation and efficacy of selection. Estimation and interpretation of Ne are essential …

Interspecific introgression is a potentially important source of novel variation of adaptive
significance. Although multiple cases of adaptive introgression are well documented …

Because reproductive isolation often evolves gradually, differentiating lineages may retain
the potential for genetic exchange for prolonged periods, providing an opportunity to …

Variation in the vertebrate major histocompatibility complex (MHC) genes is crucial for
fighting pathogen assault. Because new alleles confer a selective advantage, MHC should …

Genomic heterogeneity of divergence between hybridizing species may reflect
heterogeneity of introgression, but also processes unrelated to hybridization …

Ecologically distinct species may respond to landscape changes in different ways. In
addition to basic ecological data, the extent of the geographic range has been successfully …

The 'smooth newt', the taxon traditionally referred to as Lissotriton vulgaris, consists of
multiple morphologically distinct taxa. Given the uncertainty concerning the validity and rank …

Salamanders have some of the largest genomes among all extant organisms, due in large
part to the proliferation of repetitive elements and the expansion of intron size. This …

Aim Current genetic variation and differentiation are expected to reflect the effects of past
rather than present landscapes due to time lags, that is, the time necessary for genetic …

Hybridization between the European smooth and palmate newts has recurrently been
mentioned in the literature. The only two studies that attempted to quantify the frequency of …
