Description
Can we study evolution in the wild? Are some species “super-evolvers”?
On the episode, we talk with Alison Derry, a professor of biology at the University of Quebec in Montreal, and Andrew Hendry, a professor in the Department of Biology at McGill University, Canada. This episode is the second we’ve done on the team’s work, and Andrew was also a guest on our first episode in the series. This conversation was recorded live in front of an audience at Kenai Peninsula College, in Soldotna, Alaska.
The college is just a few miles from the lakes where Alison, Andrew, and many of their colleagues and students carry out experiments on threespine sticklebacks. We ask Alison and Andrew about their research on the rapid evolution of these fish, which were recently reintroduced to the lakes, and how the introduction of two distinct stickleback ecotypes are affecting the evolution of zooplankton in the lakes. We also discuss the central position of sticklebacks in the food web and how the sticklebacks are impacting the ecosystems now as well as how they likely impacted the lakes in the evolutionary past.
