Abstract
The systematic variation in species richness across taxonomic groups and geographic regions is one of the most striking patterns on the planet. Yet, the processes driving this variation are poorly understood. Our project aims at identifying specific ecological variables, including species’ association with the tropical or the temperate biome, that influence rates of molecular evolution and/or diversification, and ultimately species richness. We propose to develop the theoretical tools, and to compile the empirical data, necessary to analyze the patterns and process of diversification dynamics using phylogenies of extant taxa. We will model the dynamics of diversification in a non-spatial and spatial context, using individual-based and lineage-based models. We will compile a large database for flowering plants, mammals, and birds at continental/global spatial scales. This data will encompass species’ phylogeny, geographic location, a suite of ecological traits characterizing them, and fossil record when available. Applying the theory to this ambitious database, we will identify key ecological factors influencing the tempo and mode of diversification across lineages and geographic regions.
