EEB Seminar: March 14th

This week we welcome our own Jill Wettlaufer.

Resource partitioning through the seasons: a test of a competitive ability – cold tolerance trade-off among closely-related, seasonally breeding beetles

Understanding the factors that maintain and constrain biodiversity and species coexistence is a major goal in ecology. When coexisting species use similar resources, this leads to the question: Why doesn’t one species use all the resources to the exclusion of all others? Trade-offs may be key in preventing one species from dominating all resources in all environments, thus allowing multiple species to coexist. Such trade-offs may be widespread in nature and play an important role in maintaining local biodiversity, but remain poorly described and understood. In this seminar, I will present evidence of seasonal resource partitioning in closely-related coexisting burying beetles (Nicrophorus) and explore a potential competitive-ability – cold tolerance trade-off.
