Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Conservation Biology, EarlyView.Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

How identity bias affects perceptions of conservation messages on social media
Conservation Biology, EarlyView.Abstract Public support is essential for conservation, as public opinion can influence decision‐making and policy. Therefore, understanding whether bias toward conservationists due to their identity (identity bias) affects their perceived credibility and support for their recommendations is important.

野生动物学报, 2018 蛇类养殖可以缓解野外资源的开发压力,起到积极的保护作用。但是从野外非法捕捉的蛇类以人工养殖之名混入合法市场的现象也十分常见。由于缺乏有效鉴别野生和人工饲养蛇类的方法,给监管市场和打击盗猎、非法贩卖等违法犯罪行为带来困难。本研究以养殖量和盗捕量较大的王锦蛇为例,建立了肝-头指数(Ilh)和肝-体指数(Ilb)两个肝脏指数来鉴别野生和人工饲养蛇类。利用这两个指标,采用Fisher's判别将已知来源的个体进行来源回判时,两个指标的正确判别率相同,在野生组均为96.9%,饲养组均为74.1%,整体正确率为86 ...

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, EarlyView.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Zhongguo shiyan zhenduanxue, 2014 目的探讨SP70检测在良恶性胸腔积液鉴别中的临床应用价值。方法选取2011年4月至2011年12月在我院就诊并经临床明确诊断为良性胸腔积液和恶性胸腔积液患者各90例,采集患者胸腔积液标本,检测SP70、CEA、Cyfra21-1和NSE水平,并进行比较分析。结果恶性胸腔积液组患者SP70、CEA、CYFRA21-1检测阳性率分别为72.2%、58.9%和53.3%,显著高于良性胸腔积液组的10.0%、13.3%和22.2%（P0.05）。恶性胸腔积液组SP70敏感度、特异度和符合率分别为72.2%、89.

Twelve principles for successful governance of community‐based coastal marine restoration
Conservation Biology, EarlyView.Abstract Global agreements, such as the Global Biodiversity Framework, call for urgent, large‐scale action to halt biodiversity loss through a whole‐of‐society approach. Community‐based restoration can play a crucial role in achieving this goal, yet there remains limited understanding of what makes these projects effective and sustainable.

血清-腹水白蛋白梯度及腹水胆固醇测定在鉴别 良恶性腹水中的意义
Zhongshan Daxue xuebao. Yixue kexue ban, 2002 【目的】探讨血清-腹水白蛋白梯度( SAAG) 、腹水血清白蛋白比值( A/S)、腹水胆固醇( CHOL)对良恶性腹水鉴别诊断的意义。 【方法】收集 53 例腹水患者的腹水及血清,按最终诊断分为四组,分别测定血清白蛋白、腹水白蛋白及腹水胆固醇,并将结果进行比较分析。 【结果】恶性腹水 SAAG( 14. 02±8. 29)g/L 与良性腹水 SAAG( 18. 78±7. 31)g/L 有显著性差异(P

Psychometric framework for coexistence with large carnivores
Conservation Biology, EarlyView.Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...
