Nov 12 @ 1:00pm, 1132 HFH - Harold Frank Hall also known as Engineering I
Professor Cherie Briggs,
"Models of host-pathogen dynamics"
A recently discovered chytrid fungus, Batrachochytrium dendrobatidis (Bd), is having devastating effects on amphibian populations in the California Sierra Nevada, and throughout the world. In the Sierra Nevada, Bd has led to hundreds of local extinctions of frog populations, but a few populations are persisting with Bd. Efforts are currently underway, both in the Sierra Nevada and worldwide, to attempt to control this pathogen and/or limit its impact on amphibian populations. Herpetologists and ecologists are actively seeking the advice of modelers and theoreticians about what control strategies are likely to be most effective against this pathogen. In this talk, I will describe our efforts to date to develop models of the Bd/frog system, which involve models that differ from standard microparasite disease models because of the unique biology of Bd. I will discuss mechanisms by which control strategies might be effective, and areas in which further modeling work is needed.
