Scientist studying salamanders in California
Tanner Dulay on the evolution of salamanders
- January 12, 2021 -

Tanner Dulay is a PhD student at UCLA where he combines mathematical models and experiments to try to understand what makes complex ecosystems stable. He previously studied the behavior and evolution of salamanders, then helped with a project to predict how climate change will affect plants and animals in California. Along the way he became fascinated with how we can use math to make sense of the ways that organisms interact in nature. In this talk he details how ecologists have used simple clay models to find out how a common backyard salamander is evolving right before our eyes.
