Description |
IMPORTANT: This Advertiser has requested that applicants MUST be National Residents / Valid Work Permit-holders. Other applicants need not apply.
Background: The project aims to predict the effects of climate- or fisheries-induced changes in prey availability upon marine predator demography. It seeks to do this by quantifying the fundamental mechanisms that underpin this interaction, namely that energy acquired during foraging must exceed expenditure in order to avert the death of individuals and their offspring. We will use the predator-prey interaction between macaroni penguins and Antarctic krill as a case study. BAS and its collaborators have amassed a unique body of data describing seasonal foraging movements, diving behaviour, energetics, breeding success, body condition and survival of macaroni penguins at Bird Island, South Georgia, along with data on stock size, distribution, age and size distributions of krill in the surrounding waters. The project will use these existing datasets within modern inferential approaches to try and answer questions of fundamental biology. |
