For All Colleagues in Biosciences, CEE & LERN members and all at ZSL (c/o Jo Keogh) Dear All Forwarding on behalf of Tim Littlewood at the NHM for your possible interest. Best regards Jane Dempster Natural History Museum Zoology Seminars TUESDAY 27th March, 12pm Neil Chalmers Science Seminar Room (DC.LG16) external visitors ask Staff to guide you to DC2 or head for the Cocoon Parasites and Food Webs Kevin LAFFERTY Department of Ecology, Evolution and Marine Biology, University of California, Santa Barbara Ecologists use food webs to help make sense of the complexity of the natural world and the food web has become the key conceptual framework for ecology. Recently, parasitologists have pointed out that parasites make up half of biodiversity, yet are almost never included in food webs. Here, I will discuss how food webs affect parasites, how parasites affect predator-prey interactions, how parasites affect the complexity of food webs and finally what parasites can tell us about ecological complexity. I argue that most of what we have learned about food webs, and therefore ecology, is incomplete without a full consideration of parasites. D.T.J.
