Parasite Burden and Infection Duration Variation Among Individuals: Ubiquitous Patterns with a Common Cause?

Guest Speaker: Dr. Clay Cressler- University of Nebraska, Lincoln

SB010 (The Pit)

Check out the overview of this week's special presentation in the "BIO295- BioSem" seminar series....

Parasite distributions within a host population are typically aggregated, with most hosts having only a few parasites, and some having many. This pattern, known as Taylor’s law, has attracted considerable empirical and theoretical attention. Here I examine the historical distribution of parasites among fish hosts in Nebraska, showing that the pattern cannot be explained in terms of simple null models. I then propose a novel model for explaining Taylor’s law that relies on Allee effects. I show that these effects are inherent to the host-parasite interaction, and generate realistic variation in infection duration as well as the classic patterns described by Taylor’s law.

We would love to have you join us!
