Foraging Ecology and Energetic of Southern Diving Predators in Relation to Climatic Variability

The objectives of this proposal are to study the foraging strategies and energetics of the main diving birds of the Southern Ocean (especially penguins) that play in major role in food webs through a pluri-displinary study involving ecologists, physiologist and oceanographers and using bio-logging developments. We want to determine i) their foraging strategies ii) their at-sea energetics , from the individuals to the population to iii) evaluate the consequences of environmental changes on diving birds ecology. The applied issues concerns the determination of important at-sea birds areas and the use of penguins as indicators of the impact of climatic variability, at short and long term, on some poorly known food webs of the South Indian ocean.
