Tropical and subtropical Asia's valued tree species under threat

Conservation Biology, Volume 36, Issue 3, June 2022., 2022
Abstract Tree diversity in Asia's tropical and subtropical forests is central to nature‐based solutions. Species vulnerability to multiple threats, which affect provision of ecosystem services, is poorly understood. We conducted a region‐wide, spatially explicit assessment of the vulnerability of 63 socioeconomically important tree species to ...

Leader Normativity in Crisis Management: Tales From a School Fire

Risk, Hazards &Crisis in Public Policy, Volume 11, Issue 2, Page 139-165, June 2020., 2020
This study examines the handling of a school fire in a rural Swedish community and the role of the normalized narratives of leaders in crisis management. The article claims that leader normativity legitimizes certain positions and actions in a crisis management narrative and marginalizes others.

Effects of Shifting Cultivation on the Western Hoolock Gibbon (Hoolock hoolock) in Western Myanmar 刀耕火种对缅甸西部西部白眉长臂猿 (Hoolock hoolock) 的影响摘要

Integrative Conservation, Volume 4, Issue 3, Page 503-513, September 2025.
Fire occurrence increased with proximity to roads and villages, indicating that human access and activity are major drivers of fire risk. We analyzed spatial patterns of fire in relation to human settlements. Our findings highlight the need for fire management strategies that consider accessibility and human presence in conservation planning.

How Many Floods Have Occurred in China in the Past Decade? A Perspective From Social Media

Earth's Future, Volume 13, Issue 4, April 2025.
Abstract Global climate change has led to frequent and widespread flood disasters in China. Traditional flood disaster investigations mainly focus on major flood events, and small‐scale flood events are often overlooked. This study utilized the Sina Weibo social media platform to detect flood events in 370 cities in China from 2012 to 2023.

Expert assessment of illegal collecting impacts on Venus flytraps and priorities for research on illegal trade

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

The tensions of crowdsourcing disaster response in disaster‐specific Facebook groups after the Camp Fire 营地火灾后灾害专用脸书群组中出现的众包复原力组织紧张关系 Las tensiones de la resiliencia del crowdsourcing en grupos de facebook específicos para desastres después del incendio del campamento

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,

Local perceptions of anthropogenic and climate factors affecting the use and the conservation of Detarium microcarpum and Detarium senegalense in Burkina Faso (West Africa) 当地人对影响布基纳法索（西非）Detarium microcarpum（小果甘豆）和Detarium senegalense（甘豆）的使用和保护的人为因素和气候因素的看法

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 ...

带有残余应力的钢梁内嵌式预应力组合梁抗火性能研究

Jianzhu Gangjiegou Jinzhan, 2023
为研究残余应力对钢梁内嵌式的预应力简支组合梁在火灾效应下的受力性能的影响，通过ABAQUS软件建立钢梁内嵌式的预应力简支钢-混组合梁几何非线性和材料非线性的有限元模型，利用热力-耦合法计算组合梁在高温下的结构响应行为。通过对梁的截面温度、整体挠度和跨中挠度、跨中截面应力分布、拉索应力和塑性变形、梁的整体曲率和跨中曲率等特性在高温下的结构响应进行考察，探究工程应用中常见初始残余应力对组合梁的影响机理。结果表明：残余应力主要是通过影响钢梁的截面模量，进而对钢梁的截面抗弯刚度产生影响 ...

干旱区荒漠火烧迹地遥感特征分析研究—以古尔班通古特荒漠火灾为例

, 2017
西北干旱区受内陆极端干旱气候的影响，植被覆盖稀疏，生态结构简单，脆弱性明显。受自然和人为因素的影响，干旱区频繁发生的火灾已对当地经济的发展造成了沉重的压力与威胁，火灾对生态系统，尤其对干旱荒漠区生态系统的干扰特别明显。火灾是荒漠生态系统的重要影响因子，是荒漠生态系统突变的主要因素。因此，详细研究火烧迹地的发展与变化，提取火烧迹地信息对灾区生态建设与可持续发展具有重大意义，同时为有效防御火灾的发生提供科学依据，是实现当地经济与环境可持续发展的重要组成部分。传统的火烧迹地信息获取具有调查周期长 ...
