Cooperative Foraging and Food Sharing: Ifaluk Atoll

Project summary: This project is aimed at understanding cooperative foraging decisions among men of Ifaluk Atoll, Federated States of Micronesia. Data collection included time allocation, food sharing, and fishing return rate data. The data were used to examine hypotheses derived from optimal foraging theory (patch choice models) and related theories (bargaining theory, costly signaling theory) about the fishing decisions of Ifaluk men.
