Role of funders in embedding tests in conservation practice
Conservation Biology, EarlyView.Abstract Effective conservation practice requires decisions based on reliable and relevant evidence, but significant gaps in the evidence base exist. Incorporating well‐designed tests of the effectiveness of interventions for biodiversity in conservation projects is one of the best ways to scale up the rate of evidence generation.

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 ...

野生动物学报, 2007 本文论述了铜壁关自然保护区的现状、存在问题及发展对策。铜壁关保护区地理位置特殊,区系复杂,物种丰富,特有种多,对我国生物多样性保护具有十分重要的意义。但保护区至今尚未升为国家级,保护区级别低、缺乏专业技术人员、管理体制不顺等问题困扰着保护区的进一步发展。建议成立保护区管理局,理顺管理体制,扩大保护区面积,尽快升为国家级保护区,进行更为严格的管理。

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.

Dianci bileiqi, 2018 电涌保护器（SPD）是电网中常见的电气元件,可以保护电网免于电涌冲击,其可靠性对于电网运行尤为重要。文章研究了电涌保护器及其后备过电流保护的可靠性,通过对电气元件失效率曲线的分析,确定了导通线性区的极限电流值和过电流保护的功能逻辑串联的系统组成结构是决定电涌保护可靠性的主要因素,表明了电涌保护器降额设计和熔断器后备保护可以明显提高电涌保护器可靠性。

Haiyang yu huzhao本文通过对比半月湾海滩历史岸线、剖面、水下地形、沿岸输沙等的变化，详细分析了海滩的侵蚀现状，探讨了渔港防波堤建设对半月湾海滩侵蚀的动力机制，并针对性地提出了海滩修复思路。研究结果表明，半月湾海滩自渔港防波堤建设以来产生了自西向东的沿岸净输沙，海滩西侧持续侵蚀，东侧持续淤积；2004~2014年西侧岸线蚀退速率最大约为-8.10 m/a，东侧淤进速率最大约为10.10 m/a；2015~2017年年单宽净侵蚀量最大约为10.99 m3/m，2017~2021年单宽净淤积量最大约为26.05 m3/m；岸线、

Conservation Biology, EarlyView.Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

野生动物学报, 2006 通过统计1959-2005年关于大鸨的研究文献,分别从就地保护、迁地保护两个方面进行分析。结果表明:有关大鸨的研究虽从1959年开始,但直到80年代才逐渐形成系统,其中,就地保护研究数量（67．2％）多于迁地保护的研究数量（32．8％）。迁地保护和就地保护都存在研究内容比较基础的问题。在大鸨的就地保护中,保护区没有真正发挥其功效;大鸨迁地保护工作虽取得一定成就,能够保持人工饲养种群数量的基本稳定,但人工繁育技术只在部分地区取得成功,另外,应激和疾病仍是影响大鸨迁地保护工作的主要因素 ...

Assessing and strengthening community‐based coastal governance
Conservation Biology, EarlyView.Abstract Community‐based coastal governance is essential for biodiversity conservation and sustainable livelihoods, yet many communities continue to face significant challenges in establishing and sustaining effective governance systems. We sought to improve understanding of the current status of community‐based coastal governance across five countries
