Pierre’s primary interests relate to population and behavioural ecology of seabirds and other marine predators and their conservation in the face of climate and anthropogenic changes. He is also interested in trophodynamics and the use of seabirds as indicators of the state of the marine environment and their potential use in ecosystem based management. A further interest is the use of Marine Protected Areas as a conservation management tool, particularly in the Southern Cape. He is currently involved in seabird research at Marion Island, the Falkland Islands and islands along the South African coastline.
