Prof Owen Lewis
Professor of Ecology & Head of Section (Ecology and Conservation)
I am a community ecologist and conservation biologist. My interest is in the processes that maintain, structure and threaten biodiversity, particularly in highly diverse tropical forest ecosystems. My current research areas include the impact of human activities (including fragmentation and commercial timber extraction) on the diversity and functioning of tropical forest ecosystems; the structure and dynamics of food webs involving plants, insect herbivores and their parasitoids; the role of plant pathogens and insect herbivores in structuring and maintaining the high diversity of tropical plants; and the impact of climate change, habitat fragmentation and degradation on interspecific interactions and associated ecosystem functions and services.
