Underrepresentation of bats in Africa's protected areas. [PDF]
Conserv BiolAbstract Biodiversity is severely threatened globally, with habitat loss and other human pressures accelerating species extinctions. Protected areas (PAs) are a critical conservation tool; however, their effectiveness in safeguarding many taxa, such as bats, remains unclear.

Effects of snake fungal disease (ophidiomycosis) on the skin microbiome across two major experimental scales. [PDF]
Conserv BiolAbstract Emerging infectious diseases are increasingly recognized as a significant threat to global biodiversity conservation. Elucidating the relationship between pathogens and the host microbiome could lead to novel approaches for mitigating disease impacts.

Effect of primate protection on threatened and endemic vertebrates, plants, ecosystem services, and future climate refugia. [PDF]
Conserv BiolAbstract Primates, 69% of which are threatened with extinction, are the third most specious order of mammals. We used primates as model taxa to examine the umbrella effects of primates on ecosystem services and the protection of other vertebrates and seed plants in Yunnan Province, China.

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,

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 ...

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 ...

野生动物学报, 2021 海南溪树蛙（Buergeria oxycephala）是中国特有种，处于近危状态，仅分布于海南岛，预测海南溪树蛙潜在适生区可为物种保护与研究提供重要参考。依据该蛙68个物种位点数据和9个环境因子，利用最大熵模型（MaxEnt）与地理信息系统（GIS），对其在海南岛的潜在适生区进行预测，并通过刀切法和单一环境因子的响应曲线分析其与环境因子之间的关系。结果表明：海拔、气温季节性变化、坡度和气温年较差这4个因子对模型增益效果最为明显。海南溪树蛙适生区的最佳环境因子范围，海拔430—1200 m ...

野生动物学报, 2023 调查物种种群数量及适宜生境分布是合理保护野生动物和制定管理对策的基础。为了解鹅喉羚（Gazella subgutturosa）在哈密市的种群数量与适宜生境，2022年 7—9月，采用样线法对哈密市鹅喉羚种群数量和地理分布开展调查，采用Distance软件和MaxEnt模型对鹅喉羚的种群数量及适宜生境进行计算。结果表明：调查中发现鹅喉羚303群，共1 029只。鹅喉羚适宜生境主要位于天山南侧的荒漠地区，面积为1.725 9万 km2，占哈密市面积的12.15%，估算哈密市的种群密度为（2.013±0.
