Conservation Biology, EarlyView.Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Gaoya dianqi, 2019 采用抛物线拟合方法计算大容量试验短路电流波形的峰值和对应的时间坐标。理论证明短路电流波形上相邻两峰值的时间坐标中点的电流值近似等于此时的直流分量值,并据此给出波形的直流时间常数、交流（基波）分量有效值和直流分量百分数的算法。使用STL提供的标准短路电流波形,对文中算法和现有算法进行了对比测试。测试结果验证了该算法的准确性,同时表明,仅使用3个峰值点并未显著降低文中算法在计算交流分量恒定的短路电流波形参数时的准确度。通过计算直流时间常数不同 ...

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.

Differences in characteristics between naturalized threatened plants and other threatened plants
Conservation Biology, EarlyView.Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Effects of political identity activation and inaccurate metaperceptions on attitudes toward wolves
Conservation Biology, EarlyView.Abstract Polarization between groups can undermine durable conservation outcomes. Activating group identities (i.e., an individual's sense of self derived from membership in a group) can exacerbate differences, especially when people hold inaccurate perceptions of their peers and rivals.

Zhongshan Daxue xuebao. Yixue kexue ban, 2011 【目的】间质干细胞(MSC)是一种间质来源的多潜能基质细胞，目前人和多种动物来源的MSC均已被成功分离鉴定然而由于小鼠骨髓MSC的分离相对人和其他物种更为困难，关于小鼠骨髓MSC的克隆分析结果也相对有限且结果不尽一致。为此,本研究拟进一步探讨小鼠MSC的体外分离方法，并对MSC克隆形成单位进行生物学特性分析【方法】 取C57BL/6小鼠，冲洗股骨骨髓腔获得骨髓单个核细胞悬液，低密度接种培养,并通过有限稀释克隆挑选获得三种形态生长特点不同的克隆形成单位(CFU ...
