We are interested in better understanding the biology, ecology and behaviour of Pagurus bernhardus, the common hermit crab. By conducting surveys, collecting morphological data and conducting behavioural experiments, we are discovering how these charismatic crustaceans survive and thrive in their rock pool homes.

Intertidal hermit crabs live in complex, constantly fluctuating habitats. What information is relevant to them, and how do they integrate signals from the environment to make decisions? We are conducting field and lab experiments to understand how this common model organism uses the information to make decisions.

Climate change and human impacts change habitats and species distributions. These changes already affect hermit crabs and other rocky shore creatures. We are working to understand how the presence of a non-native species, the red soldier, aka St. Piran’s hermit crab (Clibanarius erythropus) will impact our native species, the common hermit crab (P. bernhardus).
