我们综合了横跨白令海岛屿的非海洋动物(哺乳动物、鸟类、鱼类、非寄生和寄生的无脊椎动物)的历史生物地理，考虑了特有现象、起源于北美和远东的物种以及通过白令地区引入的物种的影响。岛屿社区往往由独特的进化谱系组合而成，反映了由于孤立和对就地环境变化的反应而产生的中立和选择性的多样化进程。然而，目前关于白令海地区大多数陆地物种的基本分布、生态和进化特征的知识仍然普遍缺乏。与这些岛屿有关的大部分科学努力转而侧重于与海洋有关的物种和经济上可行的生物资源的养护和管理。鉴于陆地环境在维持陆地和海洋之间的进化和生态联系方面发挥的关键作用，有必要更好地了解现有的生物多样性，以及通过这一偏远地区影响社区完整性的生物过程。解决居住在岛上的物种对迅速变暖的北极气候和现代人类干扰的反应，对于有效管理未来的种群轨迹和揭示整个北半球以及海洋和陆地生态系统之间的种内和种间连通性的动态，提供了宝贵的见解。该地区位于高纬度十字路口的位置导致了具有跨柏林分布的岛屿分类群的优势。与古北区或新北区有关的物种横跨强烈的纵向梯度，反映出白令海作为大陆地区之间的扩散过滤器的作用。阿留申海洋岛屿反映了来自白令海大陆桥岛屿的不同分类群之间的不同生物地理历史。我们讨论了最近生物多样性对现代环境扰动的反应的证据，包括持续的殖民和新物种的相互作用，并呼吁加强对这些偏远前哨的陆地动物的科学审查。
We synthesize the historical biogeography of non-marine fauna (mammals, birds, fish, non-parasitic and parasitic invertebrates) occurring across Bering Sea islands, considering endemism, species with origins in both North America and Far East Asia, and the impacts of introduced species through the Bering region. Insular communities often constitute assemblages of unique evolutionary lineages that reflect both neutral and selective processes of diversification as a consequence of isolation and through responses to in situ environmental change. However, current knowledge of the basic distribution, ecology, and evolutionary identity of the majority of terrestrial species through the Bering Sea region is still generally lacking. A preponderance of scientific effort associated with these islands has instead focused on conservation and management of marine-associated species and economically viable biological resources. Given the critical role that terrestrial environments play in maintaining evolutionary and ecological linkages between land and sea, a greater understanding of existing biodiversity, and the biological processes that influence community integrity through this remote region is warranted. Resolving responses of resident insular species to rapidly warming Arctic climate and to modern human-associated disturbances provides valuable insight for effective management of future population trajectories and for revealing the dynamics of intra- and inter-specific connectivity across the northern hemisphere and between marine and terrestrial ecosystems. The location of this region at a high-latitude cross-roads has led to a preponderance of island taxa having trans-Beringian distributions. Species associated with the Palearctic or the Nearctic occur across a strong longitudinal gradient, reflecting the role of the Bering Sea as a dispersal filter between mainland areas. Aleutian oceanic islands reflect different biogeographic histories among taxonomic groups from land-bridge islands of the Bering Sea. We discuss evidence of recent biodiversity responses to modern environmental perturbations, including continued colonisations and novel species interactions, and call for increased scientific scrutiny of terrestrial fauna across these remote outposts.
