Abstract

Understanding the role of different mechanisms in shaping diversity dynamics is a major challenge in ecology and evolution. The diversity in a given region depends on the balance between speciation, extinction and migration rates. Despite a great amount of effort devoted to understand the role of the rates of speciation and extinction in diversification, we still know little about the role of migration in diversification dynamics. Immigration events result in a sudden input of diversity, which may alter local ecological dynamics affecting diversification dynamics of autochthonous lineages. The history of immigrations of terrestrial mammals and the well-documented fossil record in North America offer the opportunity to study the role of immigration on diversification dynamics. The objective of this project is to better understand how pulses of immigration affect the in situ diversity dynamics. Using quantitative analyses of the paleontological record and mathematical diversification models we intend to evaluate the role of immigration on the diversification of different groups of North American mammals, and therefore enhance our knowledge on the mechanisms that generate, maintain and eliminate diversity.
