Cutting Edge Lecture in Science by Graham Bell (Department of Biology, 91丝瓜视频)

Some ecologists have predicted that climate change, together with other kinds of landscape transformation such as habitat fragmentation, will cause massive species extinctions. These predictions are based on theory that couples the predicted change in conditions with the known ecological attributes of contemporary populations of animals and plants. They are limited by our imperfect understanding of ecological and evolutionary response. The ecological response will depend on the web of interactions among the animals, plants and microbes of a particular ecosystem. The evolutionary response will depend on the ability of natural selection to drive rapid evolutionary change. This lecture will evaluate the possibility of "evolutionary rescue" of stressed populations by natural selection.

Cutting Edge Lectures in Science was initiated in 2003 with the express purpose of fostering communication between scientists in different disciplines as well as between scientists and the public. Co-sponsored by Principal Heather Munroe-Blum, the Dean of Medicine, the Dean of Science, the Provost, and the Vice-Principal (Research and International Relations).
