Lessons from an eradication under multiple constraints of an island rat population of record density

Conservation Biology, EarlyView.
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

Specificity of the Spectrophotometry for Detecting Aminopolyether K2.2.2 in 18F-FDG

Journal of Isotopes, 2015
氨基聚醚(K2.2.2)含量是18F-FDG质控中的关键指标，比较了两种常用测量K2.2.2方法的专属性。分别采用分光光度计和半定量TLC 碘显色法测量了14个样品，其中9个阴性样品、2个阳性样品和3个供试品，并与LC-MS/MS测量对比。结果显示：9个阴性样品经分光光度计法测量均为阳性，K2.2.2的测量结果在6.7～470.0 μg/mL；2个阳性样品结果偏高（53，73 μg/mL），3个供试品的K2.2.2含量在14.3~19.2 μg/mL；半定量TLC 碘显色法测量9个阴性样品结果为阴性 ...

Strengthening community‐based fisheries monitoring programs with Indigenous perspectives

Conservation Biology, EarlyView.
Abstract Community‐based monitoring (CBM) programs are increasingly recognized as essential for adaptive environmental stewardship. Yet, the CBM literature often highlights successful cases and privileges evaluations by external experts over those of community members themselves.

基于直线法的大型变电站接地阻抗测量修正法

Dianci bileiqi, 2021
为了消除直线法测量变电站接地网接地阻抗过程中线间互感对测试结果的影响,笔者提出了一种基于直线法测量变电站接地网接地阻抗的修正法通过对直线法测量初值进行算法修正后,能有效的消除测量引线间互感对测量结果的影响。对500 kV南蔡变电站进行直线法和远离夹角法实测,并将直线法测量的数据进行修正计算,通过与远离夹角法测量的接地阻抗值进行对比分析,验证了直线修正法消除测量引线间互感影响的有效性。

Prioritizing bat roosts for conservation with a global multicriteria bat roost priority index based on community science

Conservation Biology, EarlyView.
Abstract Prioritization in conservation is crucial for the development of efficient and effective decision‐making policies. For many decades, the importance of some species and their habitats has been assessed and applied in conservation legislation, but bats and their diurnal roosts have ofbeen overlooked.

A link between increased temperature and avian body condition in a logged tropical forest

Conservation Biology, EarlyView.
Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Assessing the integration of social marketing principles in ivory demand management interventions in China and Southeast Asia

Conservation Biology, EarlyView.
Abstract Consumer demand for ivory perpetuates the unsustainable and illegal killing of African elephants and other wildlife species. Interventions that aim to change consumer behavior are increasingly recognized as a crucial element of demand management. However, poor design and implementation have limited their effectiveness.

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

How much biotic nativeness matters across human demographic groups

Conservation Biology, EarlyView.
Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

UPLC测定食用油中的3种香兰素类物质含量Determination of three vanillin compounds in edible oil by UPLC

Zhongguo youzhi
为解决现有检测方法存在前处理净化不完全、不彻底的情况，建立了超高效液相色谱（UPLC）测定食用油中香兰素、甲基香兰素和乙基香兰素含量的分析方法。用乙腈提取食用油中目标物，以乙腈饱和的正己烷萃取净化，冷冻分层后，再经Oasis PRiME HLB固相萃取柱净化，采用C18色谱柱分离，以0.5%甲酸水溶液-乙腈为流动相进行UPLC测定，外标法定量。结果表明：3种香兰素类物质在0.1~100.0 mg/L范围内线性关系良好，相关系数大于0.999，检出限均为0.03 mg/kg，定量限均为0.1 mg/kg ...
