Diets of Steller and California sea lions determined from scat collections in northwest Washington during 2010-2013 with genetic identification of salmon species

The attached excel file contains data from an analysis of the diet of Steller and California sea lions conducted in northwest Washington during 2010 through 2013. The data presented in this submission updates the data provided by Scordino et al. (2001) with new additional analyses on the salmon eaten by Steller and California sea lions. Salmon bones were sorted into three size classes (small, medium, and large) and were provided to the Institute of Science and Technology at North Central High School in Spokane, Washington for genetic analysis to determine the species of salmon consumed by the sea lions. The excel file also contains information on the sites at which scat samples were collected and data from our analysis of genotyping errors.

本次附带的Excel文件包含2010年至2013年间在华盛顿州西北部开展的斯特勒海狮（Steller sea lion）与加州海狮（California sea lion）食性分析数据。本提交材料中的数据更新了Scordino等人（2001）发布的相关数据集，新增了针对两类海狮捕食鲑鱼的额外分析内容。研究人员将鲑鱼骨骼划分为小型、中型、大型三个尺寸等级，并将样本送至华盛顿州斯波坎市北中央高中科学技术研究所开展遗传分析，以明确海狮所捕食鲑鱼的物种种类。本Excel文件同时包含粪便样本采集位点信息，以及我们针对基因分型误差开展分析所得到的相关数据。
