Understandings and critiques of biocultural diversity conservation and future recommendations for conservation actors

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract As biocultural approaches to conservation gain traction (e.g., through international commitments to Indigenous Peoples and local communities) and external conservation actors increasingly seek to engage with on‐the‐ground holders of biocultural diversity, improved understanding is needed of what biocultural diversity means.

线粒体相关基因多态性与血脂和非酒精性脂肪性肝病的相关性研究

open access: yesZhongguo shiyan zhenduanxue, 2023
目的 探讨线粒体相关基因多态性与血脂水平、非酒精性脂肪性肝病(NAFLD)严重程度的相关性。方法 研究人群包括396名具有NAFLD高风险的受试者。评估SOD2 rs4880和SOD3 rs2536512与高甘油三酯(TG)、低高密度脂蛋白胆固醇(HDL-C)、高TG/HDL-C比率和NAFLD严重程度的关联。结果 线粒体相关基因多态性与NAFLD的严重程度没有直接关系;SOD2 rs4880-CC和SOD3 rs2536512-AA,可单独增加高TG和低HDL-C水平的风险,高TG/HDL ...

Weaving knowledges to support wildlife health surveillance in Kenya's pastoral rangelands

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract In wildlife–livestock–human interfaces, pathogens capable of spreading between wild and domestic animals and humans have important implications for conservation outcomes, economics, and public health. Robust wildlife health surveillance can help address these risks.

松嫩草原西部土地利用与生态风险评价——以杜蒙县为例

open access: yesShuitu Baochi Xuebao, 2006
生态风险评价是环境、资源评价与管理方面的研究热点领域,本研究以松嫩草原西部杜蒙县为研究区域,利用该区域1979,2001,2004年3个时段的TM遥感数据、以GIS技术为数据分析平台,获取20余年不同时段的土地利用信息,研究了不同年份的土地利用类型特征。在此基础上构造一个综合性生态风险指数,然后通过系统采样、变异函数分析及空间插值对生态风险指数进行空间化,研究生态风险的空间分布特征和内在的形成机制,划分出不同风险等级区域,并有针对性的提出相应的生态风险管理措施。

Pollution Characteristics and Ecological Risk of PBDEs in Water and Sediment from an Electronic Waste Dismantling Area in Taizhou [PDF]

open access: yes, 2016
以台州某电子垃圾拆解工业园为圆心,在半径为16 km的范围内,由近及远设计了C(3 km)、S(5~10 km)和R(10~16km)三圈共30个采样点,研究了该区域水及沉积物中多溴联苯醚(PBDEs)的污染特征与生态风险.结果表明,水中PBDEs含量为9.4~57.2 ng·L~(-1),平均值为25.9 ng·L~(-1);沉积物中PBDEs含量为3.7~38 775 ng·g~(-1),平均值为2 779 ng·g~(-1);BDE-209均为主要成分.水及沉积物中PBDEs含量的空间分布态势均为:

Construction of a landscape ecological network based on landscape ecological risk assessment: A case study of the resource-based city of Linfen [PDF]

open access: yes
The changes in the landscape structure within resource-dependent urban areas is influenced by a confluence of factors, potentially resulting in a decreased landscape ecological quality and a heightened ecological vulnerability.

Robust metrics for quantifying and comparing resistance and recovery in experimental studies

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 1, Page 6-14, January 2026.
Abstract Various indices have been developed to experimentally quantify resistance and recovery (two components of engineering resilience) in response to anthropogenic and natural disturbances. This diversity complicates the selection of appropriate metrics for comparing resilience across ecosystems and studies.

Hurricane Impacts on the Population Genetics of an Endangered Ecosystem Engineer 飓风对一种濒危生态系统工程师的种群遗传学影响

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 641-651, December 2025.
Key Largo woodrats are a small and endangered island species, whose individuals tend to occur in family groups. Isolation from mainland populations, predation, and habitat fragmentation have caused genetic drift, leading to low overall diversity. Here, we found that a major category 4 hurricane promoted genetic diversity in the Key Largo woodrat ...

连续施用沼液对土壤性质的影响及重金属污染风险评价

open access: yesShuitu 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 ...
