PRELIMINARY ESTIMATION OF PENGUIN BREEDING ABUNDANCE AT SPATIAL-SCALES OF RELEVANCE TO CCAMLR: INCORPORATING UNCERTAINTY IN COUNT DATA
estimation of SSMU-specific gentoo and Adélie breeding abundance in Area 48, and similar analyses of east ... Abstract: One recommendation from the Predator Survey workshop was the undertaking of some ... for availability (e.g. nest failure) and hence would to some extent be biased estimates of the ... breeding population, and would only account for uncertainty in the accuracy of the count data. However, the ...

A bioenergetics model assessment of the prey consumption of Adélie penguins in Subarea 48.1 and 48.2
-moult period, consistent with similar studies of Adélie penguins breeding in East Antarctica. On the ... 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.
