Food webs are the conceptual framework that underpins most of community ecology. Until recently, most food webs did not include parasites. Parasites are potentially important components of foods webs. There are many parasitic species. Some of them regulate host populations. Some comprise substantial biomass. Others can alter predator-prey interactions. New food webs with parasites show that parasites have unique topological roles. Food webs also affect parasites. Many parasite species require food webs to complete their life cycles. As a result, rich and complex food webs support more parasite species. Parasites might even indicate pristine natural ecosystems.
