Next week, I’m going to talk about parasite-driven species extinctions. But first I thought it’d be fun to take a little poll. In our current mass extinction, what percentage of species extinctions do you think have been caused (i.e., extinct species) or nearly-caused (i.e., endangered species) by parasites, pathogens, or viruses? Round your answer to the nearest 10%.
This would be a good disease ecology prelims question.
