Most studies that seek to understand species diversification in deep time scales, including those focused on understanding the role of clade competition, have been done at large spatial scales. Although this is the typical approach in macroevolutionary studies, species interactions happen at local scale, and the large-scale patterns that we described should emerge from mechanisms acting at the local scale. The few studies that have looked at both spatial scales have found contradictory signals for the role of competition. In this project, we will use fossil occurrences to investigate how biodiversity dynamics at the local scale map to the dynamics described at large spatial scales. Canidae and different families of Carnivora will be used as model systems because of data availability and because those lineages have been and will be also studied at large scale. Special attention will be given to the relationship between species richness and disparity, and to clade competition.
