The opportunity provided by long summer vacation enables students to gain first-hand experience of research by assisting field projects. Links have been established with some field projects that are willing to take on Peterhouse students over the summer, and other projects can be found if students have specific interests. Existing projects include research on breeding biology in lizards and turtles in Florida and Australia. Most notably a research programme is being developed to enable students to study a remarkable new hunting behaviour in giant tortoises). A significant part of the costs of these field opportunities can be covered by Peterhouse travel grants.
