Abstract

It has been suggested that the degree of ecological diversity that characterizes a primate community correlates positively with both its phylogenetic diversity and the time since the members of that community diverged (Fleagle & Reed, 1999). Therefore, it is questionable whether or not a community with a relatively recent divergence time but high phylogenetic diversity would be as ecologically variable as a community with similar phylogenetic diversity but a more distant divergence time. To address this question, the ecological diversity of a middle Miocene platyrrhine primate community with high phylogenetic diversity but a relatively recent divergence time (members of the Honda Group from La Venta, Columbia) was compared with that of modern neotropical primate communities. Shearing quotients and molar lengths (which together are reliable indicators of diet) for both fossil and extant species were plotted against each other to describe the dietary ecospace each community occupies. Community diversity was calculated using three measure: the area of the minimum convex polygon encompassing all community members, the average distance from the centroid of the polygon to each community member, and the average distance between taxa on the bivariate plot. By these measures, the La Venta community was as diverse as most modern communities with similar phylogenetic diversity, indicating that neotropical communities have not become more diverse as the time since the common ancestor of the members of these communities increased.
