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 ...
