A bioenergetics model assessment of the prey consumption of Adélie penguins in Subarea 48.1 and 48.2
Abstract: We present a preliminary analysis to estimate the consumption of prey by Adélie ... breeding. We parameterised our analysis using data from the population of Adélie penguins breeding at Signy ... Island, South Orkneys. We show that the highest levels of consumption occur during the crèche and pre ... -moult period, consistent with similar studies of Adélie penguins breeding in East Antarctica. On the ...
