Leaders from Biology Endowed Lecture: Habitat-forming species as the mediating link between disasters (predator loss, heatwaves) and biodiversity

The mechanisms that maintain biodiversity have long been a central focus of ecology, and this area of research has taken on increased urgency as the pace of global change accelerates. I will discuss the importance of habitat-forming foundation species as key mediators of biodiversity patterns in space and time using one classical ecological concept and one recent extreme event. In classic work conducted on rocky shores, UW's own Bob Paine famously demonstrated that a keystone predator, Pisaster, promoted diversity by preventing a competitively dominant mussel from monopolizing space.

Malcom Scholar Lecture: A Crustacean's guide to surviving the Anthropocene: fiddler crab behavioral thermoregulation strategies in lethally hot environments

Behavioral thermoregulation is an important defense against the negative impacts of climate change for many ectotherms. One such example is the fiddler crab Minuca pugnax, a species that occupies thermally unstable mudflat habitats, where it uses behavioral thermoregulation, including burrow retreats, to manage body temperature (Tb).
