The Whitney R. Harris World Ecology Center at the University of Missouri–St. Louis will hold the first of its 20th Anniversary Celebration Seminars, “Longterm Dynamics in the Serengeti Ecosystem: Lessons for Conservation and Society,” at 4 p.m. on Sept. 7 in 121 Research Hall at UMSL. The lecture will be given by Tony Sinclair of the Centre for Biodiversity Research and the Department of Zoology University of British Columbia in Vancouver. The lecture is free and open to the public.

Sinclair began research for his doctorate in Serengeti National Park, Tanzania, on the population regulation of African buffalo. Subsequently, he studied the regulation of the wildebeest and other ungulate populations, looking at the effects of food supply and predation. He has examined the causes of migration and its consequences on ecosystem processes. He has documented multiple states in Serengeti savannah and grassland communities and has expanded these interests to include bird, insect and reptile faunas as part of the longterm dynamics of ecosystems. These studies have covered more than 40 years and have been synthesized in three books on the Serengeti ecosystem. He is a member of the Royal Society of London and the Royal Society of Canada.
