Towards an ecosystem status assessment for South Georgia ‘Variability of Southern Ocean Ecosystems’ Project Team
Abstract: We present the beginnings of a compilation of a suite of physical and biological ... oceanographic data, and concomitant data on abundance and condition of some key zooplankton species and ... 1999. We plan to use these data, some of which arise from the British Antarctic Survey's Core ... Programme, to develop multivariate indices of "ecosystem status". We expect that such indices will ...

Energetics of diving in macaroni penguins
free-ranging breeding female macaroni penguins. Measurement of these variables allowed estimation of ... the mass-specific rate of oxygen consumption (VO2) while diving and investigation of the physiological ... accounted for 36% of the variation in dive duration. When VO2 was calculated for dives of different ... durations, 95.3% of dives measured were within the calculated aerobic dive limit (cADL) for this species ...

The effect of temporal variability on power analysis predictions for Adélie penguin CEMP parameters at Béchervaise Island
Abstract: There are unresolved issues surrounding the use of power analyses for examining the ... ability of CEMP data to detect change. The effect size that should prompt a response if observed in a ... parameter and the likely response of parameters such as arrival or fledgling weights are two of these issues ... . Understanding the source of the variability required to generate ‘noise’ for the power analysis simulations is ...
