Bio s32 – Ecology and Evolutionary Biology of the Galapagos Archipelago – Blog

Instructors: Larissa Williams and Greg Anderson (AI)

This course studies the principles of ecology and evolutionary biology in the birthplace of the theory of evolution by natural selection. The Galapagos archipelago is one of the world’s most important and extraordinary geographic areas for ecology and evolutionary biology given its isolation, rough terrestrial terrain, and distinct oceanographic features.

Six islands in the Galapagos are visited during a 3-week trip to explore terrestrial and marine ecosystems using field biology techniques. Island habitats are contrasted to learn how the evolution and ecology of organisms has been shaped by the abiotic environment and by the spatial arrangement of the islands. Home stays and community engagement learning on the island of Isabela are an integral part of the course.

We are traveling off campus from April 28 through May 17th, 2014.  We encourage you to follow our adventures through our blog posts below.  Every day we will upload a post from a different member of the trip.
