Chemosensory speciation is characterized by the evolution of barriers to genetic exchange
that involve chemosensory systems and chemical signals. Here, we review some …

The extent to which interspecific interference competition has contributed to character
evolution is one of the most neglected problems in evolutionary biology. When formerly …

Hybrid zones between closely related species or subspecies provide useful settings for
studying the genetic architecture of speciation. Using markers distributed throughout the …

In this paper, we present results of the first comprehensive study of the introgression of both
autosomal and sex-chromosome markers across the central European portion of the hybrid …

Theoretical models suggest that geographic overlap with different heterospecific
assemblages can promote divergence of mate recognition systems among conspecific …

Studies of a hybrid zone between two house mouse subspecies (Mus musculus musculus
and M. m. domesticus) along with studies using laboratory crosses reveal a large role for the …

Instances of hybridization between endemic and alien species pose a threat to species
integrity but also provide us with an opportunity to study the dynamics of gene flow between …

Inferring the history of isolation and gene flow during species differentiation can inform us on
the processes underlying their formation. Following their recent expansion in Europe, two …

Behavioural isolation may lead to complete speciation when partial postzygotic isolation
acts in the presence of divergent‐specific mate‐recognition systems. These conditions exist …

A hybrid zone is a region where interbreeding occurs between two or more genetically
distinct populations. Recent studies have shown that mammalian hybrid zones occur in …
