Recognizing reflexivity among conservation practitioners
Conservation Biology, Volume 37, Issue 2, April 2023., 2023 Abstract When deciding how to conserve biodiversity, practitioners navigate diverse missions, sometimes conflicting approaches, and uncertain trade‐offs. These choices are based not only on evidence, funders’ priorities, stakeholders’ interests, and policies, but also on practitioners’ personal experiences, backgrounds, and values.

How to prioritize species recovery after a megafire
Conservation Biology, Volume 36, Issue 5, October 2022., 2022 Abstract Due to climate change, megafires are increasingly common and have sudden, extensive impacts on many species over vast areas, leaving decision makers uncertain about how best to prioritize recovery. We devised a decision‐support framework to prioritize conservation actions to improve species outcomes immediately after a megafire.

Fundamental insights on when social network data are most critical for conservation planning
Conservation Biology, Volume 34, Issue 6, Page 1463-1472, December 2020., 2020 Abstract As declines in biodiversity accelerate, there is an urgent imperative to ensure that every dollar spent on conservation counts toward species protection. Systematic conservation planning is a widely used approach to achieve this, but there is growing concern that it must better integrate the human social dimensions of conservation to be ...

Combined effects of land use and hunting on distributions of tropical mammals
Conservation Biology, Volume 34, Issue 5, Page 1271-1280, October 2020., 2020 Abstract Land use and hunting are 2 major pressures on biodiversity in the tropics. Yet, their combined impacts have not been systematically quantified at a large scale. We estimated the effects of both pressures on the distributions of 1884 tropical mammal species by integrating species’ range maps, detailed land‐use maps (1992 and 2015), species ...

Jianzhu Gangjiegou Jinzhan, 2023 建立了钢管混凝土内加强环式节点的ABAQUS有限元模型，通过参数分析考察了偏心对节点刚度和承载力性能的影响。在刚度方面，分别考察了偏心对节点连接刚度和节点剪切刚度的影响。在节点承载力方面，在有限元分析结果的基础上选取了较为合理的计算理论，并通过理论推导对其进行了考虑偏心影响的计算方法修正，同时在节点偏心的基础上进一步考虑了加强环厚度、加强环宽度、梁轴线夹角和节点区钢管壁厚4个参数的影响，并通过回归分析在计算理论中纳入了影响较大的参数。

Damage detection of beam-column joints in frame structures under seismic excitation based on extended Kalman filter [PDF]
, 2013 目前关于框架结构损伤诊断的研究大部分都着眼于框架结构梁柱单元的损伤,而实践证明,地震荷载下框架结构在梁柱连接节点处更容易发生损伤。然而对于复杂结构,其有限元模型存在大量的自由度,进而需要大量的传感器,相应的计算量也会加大。为了解决这一困难,文章首先用静力凝聚的方法把有限元模型降阶,然后再跟扩展卡尔曼滤波损伤识别算法结合起来进行结构的损伤识别,用一个6层钢框架的振动台试验数据对该方法进行试验验证,该试验数据由我国台湾大学罗俊雄教授提供。基于试验数据结果表明 ...

Evolution of research on global amphibian declines
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

Using online reports of seahorse seizures to track their illegal trade
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Illegal wildlife trade (IWT) is a persistent and extensive threat to global biodiversity. Hundreds of marine fish species are subject to regulation under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but it is unclear how much protection species gain from CITES because information on marine fish ...

Jianzhu Gangjiegou Jinzhan, 2021 传统的特高压输电塔塔腿设计是将塔腿结构简化为平面桁架体系进行受力分析。考虑了节点转动刚度对塔腿结构的影响,建立了半刚性连接节点的输电塔塔腿ANSYS模型。进行了平面与空间塔腿模型在不同节点转动刚度下的荷载-位移全过程分析和线刚度比的影响分析,并引入铰接和刚接模型进行对比研究。研究结果表明,节点转动刚度在很大程度上影响塔腿结构稳定极限承载力的大小,主斜材线刚度比会影响节点转动刚度的表达,且两个影响因子在平面和空间模型下都具有不同的变化规律,在用传统平面模型简化计算时应予以注意 ...
