Adélie penguin foraging behaviour and breeding success in seasons of contrasting krill availability (Mawson Coast, Antarctica)
penguins at the Béchervaise Island CEMP site were compared between seasons of contrasting krill ... particularly apparent during the late guard to early crèche stages of chick rearing, coinciding with the timing ... of the krill survey. Chick mortality peaked during this period also. The findings illustrate the ... sensitivity of parameters A5 and A8 to prey availability during the short time scale of the chick rearing ...
