This study proposes to study the biological diversity of St. Matthew Islands, a remote archipelago located in the center of the Bering Sea. This archipelago is an isolated remnant of a formerly more extensive Beringian ecosystem. They offer the chance to sample directly the remnants of a region that has had important effects on the fauna of two continents. Beringia today represents an area of considerable interest to arctic science, and this archipelago is host to several endemic species and populations. The PIs plan to collect tissue and specimens of plants, mammals, birds, and invertebrates for further systematic and ecological study. These surveys will be the first comprehensive study of the biota, and the PIs will compare their findings with historical collections and will provide baseline data for studies of the effects of global change in the Arctic. Travel to St. Matthew is extremely difficult and expensive because of the isolation and logistical requirements. The PIs plan to take advantage of unique opportunity afforded by USFWS, which is providing space for the PIs aboard their research vessel R/V Tiglax on a cruise to nearby Hall Island. Because the logistical demands are extreme and the window for opportunity is time-sensitive, the PIs have chosen to submit a proposal of limited scope under the guidelines of the Small Grants for Exploratory Research (SGER) program.

本研究拟对位于白令海中心的偏远群岛——圣马太群岛的生物多样性进行研究。这个群岛是以前广泛的白令陆桥生态系统的一个孤立的残余。它们提供了一个直接取样的机会，这个地区对两个大陆的动物群有重要影响。今天，白令陆桥代表了北极科学相当感兴趣的一个地区，这个群岛是几个特有物种和种群的宿主。pi计划收集植物、哺乳动物、鸟类和无脊椎动物的组织和标本，以进一步进行系统和生态研究。这些调查将是对生物群的第一次全面研究，pi将把他们的发现与历史收集的结果进行比较，并将为研究全球变化对北极的影响提供基线数据。由于隔离和后勤要求，前往圣马太极其困难和昂贵。美国海洋与海洋管理局（USFWS）提供了一个独特的机会，为他们乘坐研究船R/V Tiglax前往附近的霍尔岛（Hall Island）提供了空间。由于后勤需求极端，机会之窗是时间敏感的，因此pi选择在探索性研究小额赠款（SGER）计划的指导下提交有限范围的提案。
