Short Wave Climate Change Stresses Out These Chipmunks. Why Are Their Cousins So Chill?
Dec 23, 2022
Kwasi Wrensford, a PhD candidate at UC Berkeley, dives into the fascinating world of chipmunks, exploring how two species cope with climate change. He contrasts the Alpine chipmunk, which is climbing to higher elevations for cooler habitats, with the resilient Lodgepole chipmunk, thriving in its historic range. Kwasi discusses their unique adaptations and stress responses, illuminating broader implications for wildlife in a warming world. These skittish little creatures not only charm but also offer critical insights into survival strategies under climate duress.

Episode notes
Tale of Two Chipmunks
- Kwasi Wrensford studies two chipmunk species in the Sierra Nevada mountains: the Alpine and Lodgepole chipmunks.
- While similar in diet and behavior, they exhibit different responses to climate change.
Alpine vs. Lodgepole
- The Alpine chipmunk's range has shrunk due to climate change, forcing it to higher elevations.
- The Lodgepole chipmunk, however, remains in its historic habitat, demonstrating resilience.
Alpine Challenges
- Alpine ecosystems present unique challenges, including less oxygen, cooler temperatures, and shorter growing seasons.
- Climate change disrupts the timing of these seasons, impacting animals adapted to specific timeframes.
