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

野生动物学报, 2018 鸟类的行为学研究是对其进行深层次生态学研究以及开展保护和管理行动的前提,而清晰且完整的个体行为谱则是保证行为学研究在统一框架内进行的基础。作为青藏高原的特有物种,黑颈鹤(Grus nigricollis)目前仍是研究最为薄弱的鹤类之一,而其行为谱的缺乏使得有限的已有研究结果难以比较和取舍。基于此,本文于2012～2015年间在黑颈鹤的繁殖地和越冬地开展野外工作,通过野外观察以及获取的影像资料,对其个体行为进行了细致的描述并完成了个体行为谱的构建。本文以静息姿态为基础,将黑颈鹤的个体行为分为休憩行为 ...

, 2010 社会学习是动物快速获得新行为的有效途径。本研究对鳜稚鱼摄食行为的社会学习进行了检验和分析。将500尾未驯化鱼平均分配到实验组和对照组中,并在实验组中另外加入50尾已驯化鱼作为示范鱼。采用分批投饵方法群体驯化两组实验鱼摄食死饵料鱼,测量两组实验鱼摄食每批死饵料鱼的群体袭击反应时间和群体袭击持续时间。结果显示,实验组的群体袭击反应时间比对照组的稳定;实验组的群体袭击持续时间比对照组的短,且在第1次、5次、6次训练时存在显著差异。由此分析鳜稚鱼具有社会学习能力,示范鱼可能通过局域增强和反应易化社会学习过程 ...

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

不同季节对半散养黑冠鹤(Balearica pavonina)行为的影响
野生动物学报, 2016 2014年4～12月,对北方森林动物园从非洲引进的半散养黑冠鹤17只,采用目标取样法和扫描法相结合的方法对其行为进行观察和对比研究。研究结果表明:不同季节对黑冠鹤行为时间分配有明显的影响,觅食行为表现为差异性显著(P≤0.05),护理行为、静栖行为、警戒行为、鸣叫行为、打斗行为表现为差异性极显著(P≤0.01),其他行为表现为差异性不显著。8月不同天气对黑冠鹤行为时间分配的影响表现为:静栖行为表现为差异性显著(P≤0.05),觅食行为、护理行为、游走行为表现为差异性极显著(P≤0.01 ...

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity
Conservation Biology, EarlyView.Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

Regulatory compliance and support for altered management of the exotic pet trade
Conservation Biology, EarlyView.Abstract Globally, the exotic pet trade has contributed to species invasion, disease, and animal welfare risks. Although scientists have advocated for increased trade regulation, the success of management and regulatory efforts depends on compliance by participants in the exotic pet trade. We used a regulatory compliance framework to investigate exotic

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.

Informal supply chains of wild meat from rural Amazonia and food security in an urban center
Conservation Biology, EarlyView.Abstract Iquitos, the most populated city in the Peruvian Amazon, is a hub in the regional supply chain of wild meat and supplies urban consumers. Studies on wild meat consumption have focused primarily on markets, limiting the scope of species considered to those that are economically valuable and potential inferences from those data.
