Herbivory is thought to be a key process structuring vegetation in savannas, especially in Africa where large mammal herbivore communities remain intact. Exclusion experiments consistently show that herbivores impact savanna vegetation, but effect size variation has resisted explanation, limiting our understanding of the past, present and future roles of herbivory in savanna ecosystems. In this talk, I will synthesize diverse lines of evidence, including results from herbivore experiments, metabolic estimates, diet observations, and paleoecology, to evaluate the importance of top-down control on savanna ecosystem dynamics.
Carla Staver is an Associate Professor of Ecology and Evolutionary Biology at Yale University and the associate director of the Yale Institute for Biospheric Studies. She has been doing field research in South Africa since 2004, which she combines with theoretical and remote sensing approaches to scale from local to large-scale observations.
