Summary
Infections of host by multiple parasite species/genotypes have a key role in evolution of parasite virulence (harm to the host), transmission strategies and host ability to respond. This project will explore how co-infections of completely unrelated parasites are shaped by different conditions of environmental variation at within-host, among-host and host-external levels by using a combination of ecological and genetic methods. Specific questions will look into effects of factors such as temporal variation in host exposure, natural and human-induced genetic variation of hosts, and chemical and physical changes in the environment surrounding the host-parasite interaction. The project will present novel results for basic research on evolutionary ecology of multiple parasite infections, and has applied implications for management of key disease-issues in aquaculture.
