Performance anxiety: How coastal invertebrates cope with changing climate extremes (Ep 68)

What do we mean by ‘extreme ecological events’? What’s more important to a population, more frequent extremes or changes to average conditions? How should we link the performance of individuals to the success or failure of entire populations?

On this episode, we talk with Mark Denny, Stanford University professor of marine science and former director of the Hopkins Marine Station. In his 2019 paper, “Performance in a variable world,” Mark reviewed how organisms perform in highly variable environments -- a problem that has taken on new urgency as climates change. We also talk about extreme ecological events -- what they are, why they occur, and how they affect organisms. Often, extreme conditions arise from unusual combinations of otherwise normal patterns of variation in multiple underlying factors. Predicting the effects of climate extremes therefore requires holistic approaches to monitoring environments coupled with an integrative understanding of animal physiology and behavior.

This episode of Big Biology is sponsored by the Hopkins Marine Station of Stanford University. Founded in 1892, Hopkins Marine Station is the oldest marine laboratory on America’s west coast conducting research that addresses fundamental questions at every level of marine biology, from genes to ecosystems.
