Alaska Steller Sea Lion Food Habits Data 1990-2009

Description

This data set contains Steller sea lion diet data based on analysis of scats collected during summer (May-September) and winter (November-April) rookeries and haulouts in Alaska during 1990 to 2009. Prey items from 87 prey taxa were identified using hard parts including bones, otoliths, and cephalopod beaks. Frequency of occurrence was calculated for 375 site-year-season combinations, and used in the analysis published by Sinclair et al. (2013). This dataset includes the thirteen primary prey taxa (frequency of occurrence >= 5%) identified in the Sinclair et al. (2013) study.
