Abstract

Wildlife conservation is informed by detailed understanding of species demographics, habitat use, and interactions with environmental drivers. Challenges to collecting this information, particularly in remote places and on widely ranging species, can contribute to data deficiencies that detract from conservation status assessment and the effectiveness of management actions. Polar bears in James Bay face rapidly changing environmental conditions at the southern edge of their global range, but studying their ecology has been limited by community concerns about the methods typically used in polar bear research. Using a community-led and non-invasive approach, we deployed hair snare and camera trap sampling stations across 400 km of the Eeyou Marine Region in eastern James Bay. Stations collected >100 hair samples and thousands of photographs in one eight-week period that allowed for a novel investigation of this population’s distribution and body condition during the ice-free season. Polar bears were in average to above average body condition, and model selection of detections at stations revealed distance to mainland as a significant predictor of polar bear presence. Given its high potential, we suggest community-based monitoring using this method become a standard protocol to expand the scope and local leadership of polar bear research across the North.

加拿大詹姆斯湾Eeyou海洋区社区主导的无创北极熊监测:对无冰季节分布和身体状况的见解
野生动物保护是通过详细了解物种人口统计、栖息地使用以及与环境驱动因素的互动来进行的。收集这些信息的挑战,特别是在偏远地区和广泛分布的物种方面,可能会导致数据不足,从而影响保护状况评估和管理行动的有效性。詹姆斯湾的北极熊在其全球范围的南部边缘面临着快速变化的环境条件,但由于社区对北极熊研究中通常使用的方法的担忧,对其生态学的研究受到了限制。使用社区主导的非侵入性方法,我们在400个地区部署了毛发捕捉器和相机捕捉器采样站 詹姆斯湾东部的Eeyou海洋地区公里。气象站在八周的时间里收集了超过100个头发样本和数千张照片,从而对无冰季节这一群体的分布和身体状况进行了新的调查。北极熊的身体状况平均到高于平均水平,对台站探测的模型选择表明,与大陆的距离是北极熊存在的重要预测因素。鉴于其巨大的潜力,我们建议使用这种方法进行社区监测成为一项标准协议,以扩大北极熊研究的范围和在北方的地方领导地位。
