Mammalian herbivores are major drivers of terrestrial ecosystems worldwide. I study the mechanisms that drive herbivore abundance, community assemblages and their role in ecosystem functioning. My work includes herbivore-plant, herbivore-herbivore and herbivore-carnivore interactions within the abiotic setting of the ecosystem. I am exploring the (dis)similarities between browsing and grazing systems in Africa and Europe using a combination of field experiments and observational studies.
