Group associations occur during the life of most animals and often convey several adaptive advantages to the individual.   In this seminar we will discuss important concepts and adaptive models for animals that live in groups. We will read chapters from the recent book "Living in Groups" by J. Krause and G. D. Ruxton (2002, Oxford Press - available in the bookstore), related papers from the primary literature and papers of interest to class participants. This course is well-suited for any graduate student interested in organismal approaches to the behavioral ecology and evolutionary biology of terrestrial or aquatic organisms. The seminar will convene on Wednesdays from 5.30 - 7 pm in the Zoology Conference Room (next to Edm 152).
