Integrative Conservation, Volume 2, Issue 4, Page 201-213, December 2023., 2023 Livestock disturbances decreased the area of suitable habitat of forest pheasants by 14.28% in 7 years. Livestock activities remarkably increased the nest failure rate (by 2.18 times) of forest pheasants. Abstract The degradation and fragmentation of natural habitats, driven largely by anthropogenic activities such as grazing, represent growing ...

Shuitu Baochi Xuebao, 2023 为进行泥石流易发性分区及环境因子的敏感性评价,选取降水、高程、坡度、坡向、径流量、岩性、断层、归一化植被指数、土壤侵蚀模数等9个环境因子,基于最大熵(MaxEnt)模型对187个泥石流沟道进行易发性评价。结果表明:导致泥石流易发的主导因素依次是径流量、高程、降水、岩性、断层、坡度、归一化植被指数、土壤侵蚀模数、坡向。依据泥石流灾害易发概率进行易发性分区发现,贡山-福贡段泥石流易发性最强,模型AUC值为0.974,标准差为0.010,模型分析结果与实际结果一致。与研究区山洪沟道9个环境因子进行对比评价发现,

Conservation Biology, Volume 37, Issue 5, October 2023., 2023 Abstract Understanding how habitat fragmentation affects individual species is complicated by challenges associated with quantifying species‐specific habitat and spatial variability in fragmentation effects within a species’ range. We aggregated a 29‐year breeding survey data set for the endangered marbled murrelet (Brachyramphus marmoratus) from >42 ...

Integrative Conservation, Volume 2, Issue 3, Page 119-132, September 2023., 2023 Benefits derived from leisure and recreational, and wildlife cultural ecosystem services (CES) were predominantly safeguarded by nature reserves. In contrast, folk and custom CES and spiritual and religious CES were less reliant on these reserves due to intrinsic community‐based protection. Abstract Cultural ecosystem services (CES) play a pivotal role

Wildlife Letters, Volume 1, Issue 2, Page 59-70, June 2023., 2023 We used three robust modeling approaches and the largest empirical dataset yet collected for Sunda pangolin to investigate their habitat associations and the likelihood of spatially and temporally overlapping with humans. We found the species has an inconsistent response to disturbances across multiple scales, expected to be driven by Singapore's ...

Conservation Biology, Volume 37, Issue 3, June 2023., 2023 Abstract Many species are restricted to a marginal or suboptimal fraction of their historical range due to anthropogenic impacts, making it hard to interpret their ecological preferences from modern‐day data alone. However, inferring past ecological states is limited by the availability of robust data and biases in historical archives, posing a ...

, 2020 浙江开化古田山国家级自然保护区是黑麂(Muntiacus crinifrons)的集中分布区之一。近年来,保护区内黑麂面临着生境丧失和破碎化的威胁。本研究应用MAXENT模型,结合古田山保护区2014—2017年的红外相机监测数据和主要环境变量数据,对保护区内黑麂生境适宜性的季节变化特征及影响因素进行了评价与分析。结果表明:距阔叶林距离、海拔两个变量对黑麂生境适宜性的季节性变化影响最为显著。古田山保护区不同季节黑麂的适宜生境面积为:春季2 086.38 hm~2、夏季2 608.74 hm~2、秋季2 ...
