Research interests

I am interested in the structure and functioning of diverse communities and ecosystems, with special attention on how plants, herbivores, detritivores and predators interact in ecosystems. Working in a range of temperate to tropical ecosystems, I combine experimental work with the advancement of a various types new ecological theory. I frequently use the outcomes of this research for providing advice on nature conservation issues.
