Abstract

Islands are perfect spots to comprehend how the evolutionary processes takes place. In this symposium we aim to address the mechanisms that drive speciation in insular settings using case studies from the Macaronesian Region. The Macaronesian Islands (i.e. Azores, Madeira, Selvagens, Canaries and Cabo Verde), harbour biotas with exceptionally high levels of endemism, such as vascular plants, which includes some of the most important radiations in this region. Over the last decades, numerous studies have contributed to determine the phylogenetic relationships and times of origin and diversification of different endemic lineages. In this symposium we will review relevant published phylogenetic data and diversification rates retrieved within Cabo Verde plant and reptile lineages and discuss the importance of choosing appropriate phylogeny-based methods to investigate diversification dynamics on islands. We will also discuss macro and microevolutionary patterns detected within Azorean plant lineages and associated drivers of speciation. Finally, the symposium will address two of the largest radiations within Macaronesian plant lineages: (i) the Apiaceae, integrating biogeographical data and cytogenomic variation to elucidate the group’s evolutionary patterns, and (ii) the taxonomically difficult genus Limonium, through an expanded molecular phylogeny with a wide sampling of Macaronesian taxa.
