Wildlife Letters, EarlyView.Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Evaluation System of Marine Protected Area Based on Social-ecological Systems（SESs） [PDF]
, 2016 海洋保护区是保护典型海洋生态系统和生物多样性、拯救珍稀濒危物种的重要工具。目前海洋保护区数量和面积不断增加，但许多海洋保护区并未得到有效的管理，“纸上公园”式的保护区仍大量存在，保护效果不理想。保护区管理效果差的重要原因之一是缺乏定期的跟踪或对比评估，对管理中存在的问题认识不清；因此开展保护区评估对促进管理行动的适应性调整、提升管理水平非常重要。 当前保护区管理效果评估研究存在的主要问题是：评估研究对象以陆地类型的保护区为主，缺乏适用于海洋保护区特性的评估体系；评估偏重管理过程 ...

Wildlife Letters, EarlyView.Using a 3‐year, broad‐scale camera‐trap network in western Kansas, we tested whether coyotes and American badgers exhibit spatiotemporal patterns consistent with coordinated hunting. Despite high diel activity overlap, detection‐conditioned co‐detections occurred far less frequently than expected under independence, and short‐term temporal sequencing ...

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响
Conservation Biology, EarlyView.Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...

Conservation Biology, EarlyView.Abstract Prioritization in conservation is crucial for the development of efficient and effective decision‐making policies. For many decades, the importance of some species and their habitats has been assessed and applied in conservation legislation, but bats and their diurnal roosts have ofbeen overlooked.

A research on the environmental evaluation index system of provincial capitals ——Based on the Fuzhou City [PDF]
, 2016 2012年，党中央将生态文明提升到与政治、经济、社会、文化相同的高度，提出要建设美丽中国。环境保护由此进入一个新的战略阶段。环境绩效评估的有效实施，可以识别环境现状和环境目标之间的差距，判断环境政策在实施过程中的成效与不足，为各级行政管理部门制定环境政策提供科学依据和数据支撑。 本文以省会城市福州市为例，总结多年来福州市环境绩效评估的相关指标体系，探索构建基于城市定位及环境战略分区，符合区域环境现状、经济社会发展情况及环境功能定位的环境绩效评估指标体系，为明确区域环境保护重点领域，改善区域环境功能 ...

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.

Research on the value evaluation of high-tech enterprises based on Fuzzy Real Option Method [PDF]
, 2016 随着我国多层资本市场逐步健全完善，高新技术企业的投融资活动也日趋频繁。合理评估高新技术企业价值有助于相关经济活动的展开，对于促进企业发展、IPO上市、兼并等活动都至关重要。 首先本文从高新技术企业价值的特点出发，深入分析实物期权理论、模糊数学理论及企业生命周期理论在高新技术企业价值评估的适用性，为模型的改进提供了理论基础。本文针对高新技术企业价值的特点，结合生命周期视角，提出了改进的模糊实物期权模型及评估方法，以求更为合理地描述不同生命周期阶段的高新技术企业价值 ...

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.

Gaoya dianqi, 2022 为了快速评估区域电网内所有变电站的主要设备在遭遇地震灾害时的震损风险，文中通过对历年来电力设备的震害调查资料进行统计分析，将区域地震动衰减规律与设备易损性分析过程结合，得到设备在地震作用下的震损概率与震级大小和震中距的关系。在此基础上提出了区域电网内变电站设备损毁情况的震前风险评估与震后快速评估方法，并通过算例进行了模拟评估。结果表明，设备的震损概率—震中距曲线可以表征设备地震易损性随空间分布的特征，是设备震损风险快速评估方法的核心内容；该方法可同时对区域电网内所有变电站进行震损风险评估 ...
