北极理事会生物多样性工作组制定了泛北极生物多样性监测计划，以提高我们发现、了解和报告北极生物多样性长期变化的能力。北极狐(Vulpe Lagopus)因其在极地的分布、生态重要性和对北极生态系统的依赖而被确定为未来监测的目标。我们首次对当代北极狐狸监测方案进行了详尽的调查，描述了分布在8个国家的34个项目。监测种群平均覆盖物种分布的四个气候带，种群之间在长期趋势、多年波动、食物组成、与红狐的竞争程度和人为干扰等方面存在较大差异。对几乎所有种群的窝点密度、活跃窝点数量、繁殖窝点数量和窝点大小进行了评估，而在监测表明种群状况、生态系统状况或生态系统功能的其他变量方面，项目差异很大。我们回顾了加强监测项目整合的好处、机遇和挑战。我们认为，更好地协调数据收集和数据管理的协议将使新的问题得以解决，同时为个别项目增加巨大的价值。然而，尽管有许多机遇，但挑战依然存在。我们提出六项建议，代表着在更好地整合北极狐狸监测项目方面取得的决定性进展。此外，我们的工作作为一个模板，可用于整合对其他物种的监测工作，从而为未来评估全球生物多样性提供关键步骤。
The biodiversity working group of the Arctic Council has developed pan-Arctic biodiversity monitoring plans to improve our ability to detect, understand and report on long-term change in Arctic biodiversity. The Arctic fox (Vulpes lagopus) was identified as a target of future monitoring because of its circumpolar distribution, ecological importance and reliance on Arctic ecosystems. We provide the first exhaustive survey of contemporary Arctic fox monitoring programmes, describing 34 projects located in eight countries. Monitored populations covered equally the four climate zones of the species' distribution, and there were large differences between populations in long-term trends, multi-annual fluctuations, diet composition, degree of competition with red fox and human interferences. Den density, number of active dens, number of breeding dens and litter size were assessed in almost all populations, while projects varied greatly with respect to monitoring of other variables indicative of population status, ecosystem state or ecosystem function. We review the benefits, opportunities and challenges to increased integration of monitoring projects. We argue that better harmonizing protocols of data collection and data management would allow new questions to be addressed while adding tremendous value to individual projects. However, despite many opportunities, challenges remain. We offer six recommendations that represent decisive progress toward a better integration of Arctic fox monitoring projects. Further, our work serves as a template that can be used to integrate monitoring efforts of other species, thereby providing a key step for future assessments of global biodiversity.
