Abstract

The global increase of species richness towards the equator has intrigued biogeographers for more than a century. Why do nearly all groups of organisms have more species in the tropics? Although numerous hypotheses have been proposed to elucidate, the so-called latitudinal gradient of diversity, the number of species in a given clade and region is ultimately explained by four major components: (i) the time since the clade colonized the region, (ii) speciation rates, (iii) extinction rates, and (iv) biogeographic processes such as dispersal (immigration of new lineages) or vicariance (geographic isolation). In this context, South America offers a unique opportunity to investigate the function of these components in the dynamic of diversification, by both harboring nearly half of the world's biological diversity and extending across the temperate and tropical latitudinal belts. The main purpose of the ongoing postdoctoral study associated with this Research Internship Abroad Project (BEPE-PD) is to comprehend how the latitudinal diversity gradient is driven by the joint contribution of the processes of diversification, dispersal and vicariance. The proposed research to be carried out in the Norwegian University of Science and Technology will increase the knowledge of the candidate by keeping him in contact with the research group led by Dr. Torbjørn Ekrem. During this stay, the applicant will closely interact with researchers who are expert in central questions of the origin and organization of biodiversity which is expected to significantly improve the framework proposed in the associated postdoctoral study and accelerate the professional development of the candidate.
