A recurring feature of oceanic archipelagos is the presence of adaptive radiations that
generate endemic, species-rich clades that can offer outstanding insight into the links …

Anthropogenic impacts on the environment alter speciation processes by affecting both
geographical contexts and selection patterns on a worldwide scale. Here we review …

Under climate change, species unable to track their niche via range shifts are largely reliant
on genetic variation to adapt and persist. Genomic vulnerability predictions are used to …

Hybridisation and gene flow can have both deleterious and adaptive consequences for
natural populations and species. To better understand the extent of hybridisation in nature …

Stipa is a genus comprising ca. 150 species found in warm temperate regions of the Old
World and around 30% of its representatives are of hybrid origin. In this study, using …

Adaptive radiations are characterized by rapid ecological diversification and speciation
events, leading to fuzzy species boundaries between ecologically differentiated species …

The reuse of old genetic variation can promote rapid diversification in evolutionary
radiations, but in most cases, the historical events underlying this divergence are not known …

The repeated evolution of phenotypes provides clear evidence for the role of natural
selection in driving evolutionary change. However, the evolutionary origin of repeated …

Understanding the processes that drive phenotypic diversification and underpin speciation
is key to elucidating how biodiversity has evolved. Although these processes have been …

Biodiversity hotspots, such as the Caucasus mountains, provide unprecedented
opportunities for understanding the evolutionary processes that shape species diversity and …
