The Use of Penguin Stomachal Contents for the Simultaneous Study of Prey and Predator Parameters
Abstract: Penguins selectivity for krill size is shown as highly sensitive to the statistical ... assumptions made in the analysis of data. Nested designs are proposed as the correct approach because lack of ... independence between krill found in the stomach of a given penguin prevents the pooling of krill lengths from ... different samples. Samples taken at Bahía Esperanza are used to illustrate the different approaches. A ...
