Exploring Nature’s Cryptic Show: The Importance of Parasites in Ecosystems

Nicole Chodkowski,
Candidate, Environmental Sciences Ph.D. Program

Parasites are infectious agents present in every ecosystem, but their effects on ecosystem functioning are largely unexplored. Parasites can maintain disproportionate biomasses, alter nutrient stoichiometry, and manipulate hosts causing them to act functionally different from unparasitized individuals in some ecosystems. Although parasites may ultimately contribute to ecosystem function, few studies have considered these large-scale ecosystem effects.

This seminar will provide a general overview of why parasites should be considered in ecosystem studies and explore the ecosystem effects on parasite abundance and distribution.
