Conservation Biology, Volume 38, Issue 5, October 2024.Abstract Illegal collecting of wild Venus flytraps (Dionaea muscipula) for the horticultural trade represents a persistent threat to populations of the species across their endemic range in the coastal plain of North and South Carolina (United States). Although wild collecting of Venus flytraps is not a novel threat, there has been very little research

Gaoya dianqi, 2022 特高压换流变压器火灾会对防护区内干式消防管道造成干烧,连接件及其密封受损会造成大量漏水,甚至导致灭火系统整体失压。结合某特高压换流变压器真型灭火试验典型温度,对目前标准规定的干烧试验方法进行分析,并提出通过涂覆钢结构防火涂料提升特高压换流变压器消防管道抗干烧性能的措施。根据真型灭火试验升温特点设计试验装置,所得温度曲线可以较好反映实际火灾热环境状态。对涂覆不同厚度钢结构防火涂料的消防管道连接件进行干烧试验,结果表明,实际工程中可以采用钢结构防火涂料对特高压换流变压器消防管道进行耐火防护 ...

Risk, Hazards &Crisis in Public Policy, Volume 15, Issue 2, Page 261-283, June 2024.Abstract Disaster‐specific Facebook groups (DSFGs) are Facebook groups devoted to a specific disaster or set of disasters. I argue DSFGs offer opportunities for disaster response and resilience organizing that can mitigate the limitations of institutionalized disaster response and illustrate the benefits and detriments of the use of DSFGs by survivors ...

Experimentally testing animal responses to prescribed fire size and severity
Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Deserts are often highly biodiverse and provide important habitats for many threatened species. Fire is a dominant disturbance in deserts, and prescribed burning is increasingly being used by conservation managers and Indigenous peoples to mitigate the damaging effects of climate change, invasive plants, and land‐use change. The size, severity,

Integrative Conservation, Volume 3, Issue 1, Page 58-75, March 2024.Local populations are aware of the decline and disappearance of Detarium species in their habitats, attributing this trend to excessive human exploitation and the effects of climate change. Thus, Detarium plant resources may face challenges in forests with different levels of protection status due to habitat fragmentation and the effects of climate ...

, 2003 火山灾害风险评估是火山减灾的重要研究内容之一。长白山火山是中国最具潜在喷发危险的活火山。围绕火山灾害危险性、致灾因子危险性、社会经济易损性,发展了基于GIS和RS的火山灾害风险评估面源模型,对长白山火山灾害风险进行了评估,并编辑了长白山火山灾害风险评估图。研究表明,长白山火山灾害风险在空间上表现为距离衰减规律,离天池越远,风险值等级越低;高风险区位于天池附近,围绕天池呈环状展布;较高风险区向东北方向延伸,主体位于安图境内;中风险区范围相对较大,主要位于安图、和龙、长白、靖宇、抚松境内 ...

Theorizing reactive policy entrepreneurship: A case study of Swedish local emergency management
Policy Studies Journal, Volume 52, Issue 1, Page 73-89, February 2024.Abstract In this article, we examine public policy change at the local level of governance in the aftermath of an extraordinary event. Using the case study of a Swedish municipality after the sweeping forest fire of 2014, we contend that policy entrepreneurship, like its market counterpart, may under certain conditions take on a wider range of ...

, 2011 火是地球系统的重要组成部分,与气候、植被、生物地球化学循环和人类活动密切相关。火对全球气候和生态系统的影响已成为目前全球变化研究的一个热点。火灾发生后会在周围的环境中留下许多燃烧产物,如黑碳、木炭屑、多环芳烃、左旋葡萄糖等,它们广泛存在于海洋、湖泊、河流、土壤和陆地风成沉积物中;还会留下一些火灾痕迹,如树木火疤、土壤磁学参数的改变。通过这些记录不仅可以反映火活动的历史,同时能够反映历史时期的气候条件及植被格局,为火灾历史重建提供宝贵的信息资料 ...
