Quantifying within- and between-season variability in Adélie penguin fledgling weights: statistical and practical implications for detecting change
Abstract: We develop statistical models of Adélie penguin fledgling weight data collected at ... Béchervaise Island and use them in a power analysis as a continuation of the CEMP review. The statistical ... models incorporate both within- and between- season variability of fledgling weights from first ... attempts at incorporating multiple sources of variability rather than final products because a number of ...

Sea surface temerature anomalies near South Georgia: relationships with the South Atlantic and the Pacific El Niño regions
Abstract: The sea surface temperature dataset of Reynolds and Smith (1994) was used to describe ... variability around South Georgia. High levels of autocorrelation were evident in the sea surface temperature ... anomalies, with periodicity evident at a lag period of 4 years. To the north of the island significant ... autocorrelation was also evident at a lag period of 1 year; though this was restricted to an area that ...
