  10. The effect of temporal variability on power analysis predictions for Adélie penguin CEMP parameters at Béchervaise Island

    this paper have similar power estimates because their estimates of temporal variability are comparable ... 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 ...
