Project summary
This project will investigate whether urban coastal environments alter fear-related behavioral and physiological responses in wild hermit crabs, using two species that differ in their history of exposure to urbanization. Researchers will compare crabs of both species collected from urban and rural shorelines and measure indicators that may be linked to affective state, including startle responses, shell investigation behavior, and resting metabolic rate under field conditions. By repeatedly measuring behavior within individuals, they will also test whether urban disturbance influences behavioral predictability, which may provide additional insight into fear and stress-related processes.
Why we funded this project
This project applies concepts and analytical approaches from animal personality research to the assessment of welfare-related states in free-living animals. It also addresses a priority taxonomic gap in the field: Crustaceans are abundant yet remain largely neglected in wild animal welfare research, despite growing evidence for their behavioral complexity and sentience-related capacities.
