Sources of variability associated with Adélie penguin CEMP parameters measured at Béchervaise Island, East Antarctica
Abstract: We examine the magnitude of a variety of sources of variability associated with CEMP ... parameters. The CEMP parameters considered in this paper include: A3: breeding population size, A1: arrival ... parameters at around 5-7% CV. The smallest source of variability was associated with measurement error ... although this source of variability is difficult to assess. The largest source of variability was related ...
