Hybrid WN@tL: “How a Fish Lost (and Regained) Its Worm: Evolutionary Genetics of Host-parasite Interactions.”

August 10 @ 7:00 pm - 8:00 pm

Speaker: Jesse Weber, the Department of Integrative Biology

Description:  Marine threespine stickleback (Gasterosteus aculeatus) are highly susceptible to Schistocephalus solidus tapeworms, but freshwater populations across the globe have evolved to resist the parasite. Interestingly, freshwater fish in different areas evolved resistance via different mechanisms, and parasites evolved to counter the resistance of their local hosts.

We can replicate the parasite’s complex life cycle in the lab. This allows us to perform thousands of controlled exposures between different host and parasite populations.  These experiments allow us to pursue pivotal questions in parasitism, including: 

What genetic changes underlie host-parasite coevolution?  

How often are new genes or strategies deployed, as opposed to recycling existing variation?

How does gene flow among many populations impact the rate and trajectory of (co)evolution?
