, 1989 本文通过对电感耦合等离子体热导系数计算结果的分析,得知电感耦合等离子体中的温度梯度能引起等离子体内部每平方厘米几十瓦的热流。对各种温度的计算表明,电子温度为10000°K时,离子温度和原子温度约9000°K。对高能电子密度,计算结果的分析表明,分析等离子体区的高能电子密度大大偏离了Moxwel分布 ...

Conservation Biology, EarlyView.Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

粪便显微分析和DNA宏条形码技术在野猪食性分析中的应用和比较
野生动物学报, 2022 有蹄类动物食性分析对基础生态学研究乃至大型濒危食肉动物保护与恢复有重要科学价值。食物组成定量化有很多方法,常用的方法有粪便显微分析和DNA宏条形码技术,但各有其优缺点。2014年12月—2016年3月,在珲春、汪清、黄泥河、天桥岭和穆棱5个地区收集了野猪(Sus scrofa)新鲜粪便样品,运用粪便显微分析和DNA宏条形码技术比较研究了冬季野猪食性。仅对比分析了野猪植物性食物,通过粪便显微分析获得的野猪食物组成包含32属植物,比例大于4%的主要食物有木贼属(Equisetum,(22.76±1.87)%)

Drivers of bat researchers’ intent to adopt field hygiene practices
Conservation Biology, EarlyView.Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Analysis on the reliability of reanalysis surface flux datasets for China(我国范围内多个再分析地表通量数据集的可信度分析)
Zhejiang Daxue xuebao. Lixue ban, 2006 利用NCEP/NCAR (NCEP1)、NCEP/DOE(NCEP2)及ECMWF的再分析地表通量（感热和潜热通量）资料，以及由经验公式计算得出的我国地表通量的气候值（以下简称气候值），采用可视化分析、统计分析和天气气候学诊断方法，分析了三组再分析数据集的地表感热、潜热通量，以及基于地表热通量的鲍文比和地表热源在不同季节的空间分布和年变化，并与气候值做了比较.结果显示，尽管存在一些共同的问题（如三组再分析数据集潜热通量的值明显偏大），但不同再分析地表通量所反映的我国不同季节地表感 ...

基于电子转移/高能碰撞解离质谱碎裂的O-GlcNAc糖基化位点定量分析方法在高脂喂养小鼠肝脏糖蛋白质组分析中的应用
, 2021 O-连接N-乙酰葡糖胺翻译后修饰(O-GlcNAc)是发生在蛋白质丝氨酸或者苏氨酸位点上的单糖修饰,由于其具有化学计量数少、在质谱鉴定中离子化效率低以及无特定的氨基酸序列等特点,使O-GlcNAc翻译后修饰位点的定性和定量分析难度较大。本研究结合基于凝集素弱亲和色谱的O-GlcNAc修饰糖肽富集方法、本研究组发展的准等重六重标记定量方法和电子转移/高能碰撞解离(EThcD)模式的高分辨质谱技术,发展了一种O-GlcNAc修饰位点的高通量定量分析方法,对高脂喂养小鼠肝脏中蛋白质O ...

Conservation Biology, EarlyView.Abstract Although significant biodiversity has been safeguarded by protected areas (PAs), biodiversity trends continue downward. Within the frameworks of the EU Biodiversity Strategy for 2030 and the new EU Restoration Regulation (2024), conserving critical biodiversity areas is essential.

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, EarlyView.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Conservation Biology, EarlyView.Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...
