Investigating the spread of infectious diseases with NSF, NIH, UK funding

lity of cholera and other waterborne diseases to invade, spread, and remain in a population.

Title: Disease at the margins of species ranges: anther-smut on alpine species.
PI: Janis Antonovics, University of Virginia
Summary: This project will address questions about how the spatial distribution of a species is influenced by disease. Researchers will conduct experiments on alpine plant populations to determine the role of a fungus in regulating the spread of its host plant species, as well as whether host individuals at the edge of their species' ranges are more likely to contribute to cross-species disease transmission.

Title: Modeling infectious diseases: how much ecological complexity must we address?
PI: Armand Kuris, University of California - Santa Barbara
Summary: In nature, a parasitic species inhabits a complex world of interactions among alternative hosts, competitors for resources, and the environment. However, mathematical models used to study infectious disease dynamics typically reduce this system to a simple depiction of only a single pathogen in a single host population. To test how much influence the ecological complexity of a system has on disease dynamics, scientists will study parasitic diseases in several estuaries along the coast of California and Baja California and will model parasite dynamics in food webs of different complexity, under different temperatures, and for parasites with complex life cycles.
