Integrative Conservation, Volume 2, Issue 3, Page 133-139, September 2023., 2023 Invertebrate‐derived DNA (iDNA) has enabled the identification and quantification of ecological interactions within trophic networks and its use in biodiversity assessment. The dung beetle iDNA currently uses live beetles. However, the effectiveness of the iDNA approach hinges on the successful detection of mammalian DNA from specimens collected via ...

Importance of health assessments for conservation in noncaptive wildlife
Conservation Biology, Volume 36, Issue 1, February 2022., 2022 Abstract Wildlife health assessments help identify populations at risk of starvation, disease, and decline from anthropogenic impacts on natural habitats. We conducted an overview of available health assessment studies in noncaptive vertebrates and devised a framework to strategically integrate health assessments in population monitoring.

野生动物学报, 2022 粪便皮质醇激素对衡量动物应激强度具有较好的指示作用,但其检测准确性受诸多因素影响。为了评估不同取样方式对大熊猫(Ailuropoda melanoleuca)粪便皮质醇测定产生的影响,将粪便横向纵向四等分分割,采用冻干研筛法与酶联免疫吸附法(ELISA)处理每部分粪便和测定激素含量,旨在分析粪便激素分布情况以进一步探讨取样对策。结果显示:每部分粪便的皮质醇含量无显著差异(df=3,F=0.033,P=0.992),粪便在四等分处理下的激素分布比较均匀,即每部分粪便激素均能在一定程度上代表整体水平。1 ...
