THIS IS A PAST EVENT.

Professor Nicholas Kortessis, WFU Biology, "More than just noise: Embracing environmental variability and its consequences for ecology" (host: S. Winter)

Abstract:

A conspicuous feature of ecological systems is the fact that conditions are rarely the same across space and time. An enduring challenge is to understand how heterogeneous conditions affect individuals, populations, and species, and use that understanding to make predictions. Mathematical models in ecology traditionally represent environmental variability as white noise, that is, independent random perturbations to dynamics that occur under constant conditions. But such a characterization often limits our understanding of potentially relevant biological processes. In this talk, I will give two examples of how environmental noise interacts with population growth processes to yield novel, emergent phenomena. The first example illustrates how changing environments present opportunities for multiple species to coexist despite competition between them. The second example illustrates how spatio-temporal heterogeneity accelerates population growth. I will demonstrate how local SARS-CoV-2 mitigation policies blind to this effect might inadvertently exacerbate viral spread. Throughout, I emphasize how environmental noise interacts with deterministic processes to yield surprising outcomes.
