Project Synopsis
Population ecology of Risso's dolphins off Taiwan

The Risso’s dolphin (Grampus griseus) is one of the medium-size cetacean species commonly encountered off the east coast of Taiwan.  I am interested in population ecology of Risso’s dolphins, especially their spatiotemporal pattern of distribution and spatio-behavioural pattern of habitat use.  I want to document whether there are any specific sites and habitats off the Taiwanese coast that this species uses more frequently for specific behaviours such as foraging, resting or social interactions.  Using data on individually identifiable animals and mark-recapture techniques, I will estimate population parameters such as temporary migration patterns, affinities to any specific geographic locations, reproductive parameters and population size.  My project is conducted in collaboration with several dolphin and whale watching operators and includes considerable amount of public outreach and education.
