Summary of prey groups found in harbor seal scat samples from the San Juan Islands analyzed at the Acevedo lab at Western Washington University during 2005-2008 (Seal_response_to_prey project)

<p>Frequency of occurrence of taxonomic groups of prey identified in harbor seal scat samples collected from 2005 to 2008, summarized by region and season. Four regions of the San Juan Islands of Washington state were sampled: Eastern Bays, Rosario Strait, San Juan Channel, and the Southern Strait of Georgia.</p>

<p>本数据集呈现2005至2008年间采集的港海豹（harbor seal）粪便样本中鉴定出的猎物分类群出现频率，按区域与季节进行汇总。本次采样覆盖华盛顿州圣胡安群岛的四个区域：东部海湾（Eastern Bays）、罗萨里奥海峡（Rosario Strait）、圣胡安水道（San Juan Channel）以及南乔治亚海峡（Southern Strait of Georgia）。</p>
