In case you’re seeing Megan McPhaden’s defense this morning, the best way to keep your neurons firing when she’s done is to join Ailene Ettinger in the Forest Club at 12:30 p.m. as she defends her dissertation, “Testing the Limits: Understanding How Climate and Competition Affect Species Ranges in a Warming World.”
Rising temperatures could result in tree range shifts. Indeed, scientists have already observed that many species ranges have moved upward in latitude and altitude as global temperatures have increased during the past century. However, competition with neighboring trees can also affect species distributions, which means that global warming may not always result in range shifts. Ettinger’s dissertation research investigates these issues by examining how climate (including temperature, rain and snow) interacts with competition to determine the performance of common tree species at Mount Rainier National Park.
Her committee chair is Biology Professor Janneke Hille Ris Lambers, and other members include Martha Groom, Joshua Tewksbury and SEFS Professors Josh Lawler and Tom Hinckley.
Your brain will be hungry, so feed it!
