Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Shuitu Baochi Xuebao, 2018 为实现沼液资源化利用，采用3年田间定位试验研究施用猪粪沼液对土壤理化性质的影响，并评估其对土壤潜在的重金属污染风险。田间试验种植方式为水稻—油菜轮作，施肥方式分别以清水和常规化肥为对照，另设10个猪粪沼液施用量梯度。通过单因子污染、内梅罗综合污染和Hakanson潜在生态风险指数法，评价连续施用猪粪沼液对土壤潜在的重金属污染风险。结果表明：当3年沼液施用总量为（546.25~626.00）×103 kg/hm2时，能显著提高土壤肥力，改善土壤结构，防止土壤生态功能遭破坏，保障农业安全生产 ...

Prospects and perils in the geospatial turn of conservation
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Conservation has embraced advances in big data and related digital technologies as key to preventing biodiversity loss, especially in the identification of areas of conservation priority based on spatial data, which we call the big geospatial data turn.

A global indicator of species recovery
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Monitoring progress toward meeting global biodiversity goals involves several indicators, including, at the species level, the International Union for Conservation of Nature (IUCN) Red List Index (RLI) and the Living Planet Index (LPI). However, at present, there is no indicator specifically for tracking species recovery, despite this being ...

Assessing ecological risks of heavy metals to marine organisms in the Jiulongjiang Estuary by species sensitivity distribution [PDF]
, 2014 采用物种敏感性分布法(SSd)构建常见重金属元素对海洋生物的SSd曲线,结合九龙江口水体5、8、11月份21个站位重金属调查数据,计算了九龙江口7种重金属(AS,Cd,Cr,Cu,Hg,Pb,zn)不同暴露浓度对海洋生物的潜在影响比例(PAf),并分析了在相应站位重金属复合污染生态风险(MSPAf)。结果表明,7种重金属中AS的生态风险最大(即PAf值最高);时间尺度上,5月份总的MSPAf较其他月份稍高;空间尺度上,西溪至海门岛(1~7号站位)污染较严重 ...

Community‐informed and codesigned research to understand the impacts of railways on wildlife
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Trains cause mortalities of several animal species, but the ecological impacts of railways are understudied. Most research on wildlife–train collisions has focused on large mammals, but understanding railway‐specific risks for underrepresented taxa, especially vulnerable species, is important for developing effective mitigation strategies ...

Study on Ecological Risk Assessment in Quanzhou Bay [PDF]
, 2009 海湾作为海岸带区域的重要地理形态，是海洋与人类联系最为密切的部分之一，它同时受来自海洋和陆域两个方向的强烈影响和作用，一方面具有资源类型丰富，生产力较高的特征；另一方面又具有水交换能力差，自然灾害易发的特征。同时海湾作为人类强烈干扰作用的承受区域，环境相对敏感，生态系统交错区的边缘效应突出。海湾的区域特殊性导致其由人为风险源和自然风险源所带来的风险压力巨大，因此海湾生态系统风险研究作为海湾生态系统研究的重要组成部分，通过辨识主要风险源及压力，分析评估其对风险受体的影响和作用 ...
