The habitat plays a crucial role in ensuring the survival of wildlife. However, the increasing disturbances caused by human activities present a substantial threat to habitats, especially for species such as the leopard cat (), which is a significant small predator. Currently, research on leopard cats predominantly focuses on low-altitude regions within its distribution range, leaving plateau areas understudied. To enhance our understanding of the impact of human disturbances on leopard cat habitats, we undertook a study employing infrared camera trappings to monitor leopard cats' activity in Xinlong of southwestern China between 2015 and 2023. We analyzed the spatial distribution and habitat suitability of the leopard cats by utilizing ensemble species distribution models (ESDMs). Moreover, we employed two-species occupancy models to investigate the spatial interaction between leopard cats and human disturbances. The results indicated that (1) the potential suitable habitat area for leopard cats encompassed approximately 1324.93 km (14.3%), primarily located along the banks of Yalong river. (2) The distribution of suitable habitat was predominantly influenced by competitors, specifically the yellow-throated marten (YTM), accounting for 52.4% of the influence, as well as environmental factors such as distance to water (DTW) at 12.0% and terrain roughness index (TRI) at 10.0%. Human interference, including cattle presence (4.6%), distance to road (DTD, 4.9%), and distance to settlement (DTS, 3.5%), had a limited impact on the habitat distribution. (3) Within a 5 km radius, habitat suitability increased with proximity to human settlements. (4) Leopard cats exhibited spatial independence from humans and domestic cattle (species interaction factor (SIF) = 1.00) while avoiding domestic horses (SIF = 0.76 ± 0.03). The relatively minor impact of human disturbances in Xinlong could be attributed to traditional cultural practices safeguarding wildlife and the leopard cat's environmental adaptability. We recommend establishing a novel conservation paradigm based on the living dynamics of wildlife communities in Xinlong, thereby offering a more targeted approach to biodiversity preservation in the future.
栖息地对于确保野生动物的生存起着至关重要的作用。然而,人类活动造成的干扰日益增加,对栖息地构成了重大威胁,尤其是对于豹猫(Prionailurus bengalensis)这种重要的小型食肉动物而言。目前,对豹猫的研究主要集中在其分布范围内的低海拔地区,高原地区则研究较少。为了加深我们对人类干扰对豹猫栖息地影响的理解,我们开展了一项研究,利用红外相机诱捕技术在2015年至2023年间监测中国西南部新龙地区豹猫的活动。我们通过利用集合物种分布模型(ESDMs)分析了豹猫的空间分布和栖息地适宜性。此外,我们采用双物种占用模型来研究豹猫与人类干扰之间的空间相互作用。结果表明:(1)豹猫的潜在适宜栖息地面积约为1324.93平方千米(占14.3%),主要位于雅砻江沿岸。(2)适宜栖息地的分布主要受竞争者影响,特别是黄喉貂(YTM),影响占比52.4%,以及诸如距水距离(DTW)占12.0%和地形粗糙度指数(TRI)占10.0%等环境因素。包括牛的存在(4.6%)、距道路距离(DTD,4.9%)和距定居点距离(DTS,3.5%)在内的人类干扰对栖息地分布的影响有限。(3)在半径5千米范围内,栖息地适宜性随着与人类定居点距离的缩短而增加。(4)豹猫在空间上与人类和家牛相互独立(物种相互作用因子(SIF) = 1.00),同时避开家马(SIF = 0.76 ± 0.03)。新龙地区人类干扰影响相对较小,这可能归因于保护野生动物的传统文化习俗以及豹猫的环境适应性。我们建议基于新龙野生动物群落的生活动态建立一种新的保护模式,从而为未来的生物多样性保护提供更具针对性的方法。
