I am interested in how parasites fit into ecological food webs. Food web theory has developed over the last 80 years without much consideration being given to the role of parasites because ecologists generally assumed that parasites were too small to be a significant force in the structuring of communities. However, it is now indisputable that the negative effects of parasites on individual hosts can cascade up to the population and community levels. Nevertheless, integrating parasites into modern food web theory has been problematic. After almost a century of ignoring parasites, it has proven difficult to retrofit parasites into the complicated theory and equations that have evolved in this field.
I argue that the same thermodynamic principles that govern all organisms in an ecosystem should also govern all parasite interactions. This conception of energy flow as the major structuring force in ecosystems (Lindeman, 1947; Teal, 1953; Odum, 1953) is a fundamental principle that still underlies all food web theory. Thus, I propose a return to the ideas of community organization first articulated by the early ecologists, and the undertaking of rigorous studies that incorporate parasites into these early models. At the Center for Research on Animal Parasites (C.R.A.P.), we investigate patterns of energy flow through aquatic ecosystems to get reliable and empirical estimates of the energetic costs of parasitism at all levels of organization.
