Speciation is a fundamental evolutionary process, the knowledge of which is crucial for
understanding the origins of biodiversity. Genomic approaches are an increasingly …

Environmental gradients are very common and many plant species respond to them through
adaptive genetic change. This can be a first step along a continuum of change that leads …

The cichlid fish radiations in the African Great Lakes differ from all other known cases of
rapid speciation in vertebrates by their spectacular trophic diversity and richness of …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

The role of interspecific hybridization in evolution is still being debated. Interspecific
hybridization has been suggested to facilitate the evolution of ecological novelty, and hence …

Despite their evolutionary relevance, multispecies networks or syngameons are rarely
reported in the literature. Discovering how syngameons form and how they are maintained …

'Species' are central to understanding the origin and dynamics of biological diversity;
explaining why lineages split into multiple distinct species is one of the main goals of …

Microbes can have profound effects on their hosts, driving natural selection, promoting
speciation and determining species distributions. However, soil‐dwelling microbes are …

Mapped geographical distributions of many birds are an overestimation of their true range
and this overestimation is particularly high for threatened species. Due to their restricted …

Hybrid zones typically form as a result of species coming into secondary contact, but can
also be established in situ as an ecotonal hybrid zone, a situation which has been reported …
