Current Research:

I am interested in how parasites might fit into ecological food webs. Food web theory has developed over the last 80 years (since Elton 1927) without much consideration being given to the role of parasites. Ecologists still generally think that parasites are too small to be a significant force in the structuring of communities. It is indisputable that parasites can have negative effects on their individual hosts, but it is not clear how these effects cascade up to the level of populations or communities. Integrating the effects of parasites into modern food web theory has been problematic. After almost a century of ignoring parasites, it is difficult to retrofit parasites into the complicated theory and equations that have evolved in this field.

The best way to bring parasites into food web theory is return to the early ideas of community organization first articulated by Lindeman (1947) and Odum (1953). Their conception of energy flow of as the major structuring force in ecosystems is still the fundamental principle underlying all food web theory. I argue that the same thermodynamic principles that govern all organisms in an ecosystem, should also govern all parasite interaction. In my research we look at patterns of energy flow through aquatic ecosystems to get estimates of the energetic costs of parasitism at all levels of organization.
