Conservation Biology, EarlyView.Abstract In the western United States, conservation practitioners are increasingly working with private landowners to restore habitat for North American beavers (Castor canadensis) and to use nonlethal mitigation techniques when beavers damage crops and infrastructure.

World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Weaving knowledges to support wildlife health surveillance in Kenya's pastoral rangelands
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract In wildlife–livestock–human interfaces, pathogens capable of spreading between wild and domestic animals and humans have important implications for conservation outcomes, economics, and public health. Robust wildlife health surveillance can help address these risks.

, 2018 几何非线性是土木工程结构在强震作用下动力时程分析过程中必要的考虑因素。该文基于数值子结构方法,结合平面Euler-Bernoulli梁柱单元的几何大变形理论,将平面框架结构的非线性分析转化为线弹性主结构的弹性分析,并提出材料和几何非线性修正力项,作为等效为外荷载项施加于主结构以考虑结构的双非线性。最后,对一平面钢框架结构进行地震动力时程分析,分析结果表明考虑了双非线性的数值子结构方法具有良好的精确性与高效性;同时,几何非线性对结构动力响应具有重要影响。国家自然科学基金项目(51261120376 ...

Characterizing China's Illegal Trade in Avifauna on Social Media 中国社交媒体上非法鸟类贸易的特征分析
Integrative Conservation, Volume 4, Issue 4, Page 616-626, December 2025.Worldwide, illegal wildlife trade is an increasing threat to species conservation. Here, we used the social media data to characterize China's illegal online trade in avifauna for conservation implications. Our results found that 178 avian species have been posted online for illegal trading. ABSTRACT The illegal wildlife trade poses a growing threat to

, 2012 通过开展离心机动力试验,揭示了从基岩输出的地震波经过一定厚度的软粘土层传播到地表时,地震波高频成分将被过滤,地表运动的周期将变长,反映出土体在地震荷载的持续作用下将发生一定程度的软化,同时在一定的周期范围内,加速度反应谱幅值将得到不同程度的放大;最后开展了ABAQUS计算和理论分析以验证试验结论的合理性。该研究为自由场土体地震反应的基础性研究 ...

Community‐informed and codesigned research to understand the impacts of railways on wildlife
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Trains cause mortalities of several animal species, but the ecological impacts of railways are understudied. Most research on wildlife–train collisions has focused on large mammals, but understanding railway‐specific risks for underrepresented taxa, especially vulnerable species, is important for developing effective mitigation strategies ...

Dianci bileiqi, 2019 1 000 kV避雷器高度高,荷载大,结构重要性高,在地震中易损性极高。基于ANSYS有限元软件,建立了基于土与结构相互作用的1 000 kV避雷器有限元模型,输入地震波进行动力时程响应分析。结果表明,考虑土与结构相互作用后,避雷器顶端位移、瓷套应力和倾覆力矩并不是随着土体剪切波速的减小一直增大或减小,当土体较硬时对地震动起放大作用,相应结构动力响应变大,当土体较软时对地震动起隔震作用,结构动力响应变小。

Politics &Policy, Volume 53, Issue 5, October 2025.ABSTRACT Policy evaluation is crucial for effective governance and development in the Global South, yet its institutionalization is shaped by a complex interplay of historical, political, and transnational factors. This study examines how colonial legacies, domestic political dynamics, and external influences converge to influence policy evaluation ...

Wildlife Letters, Volume 3, Issue 3, Page 91-98, September 2025.The edge densities of cropland, developed land, and water bodies (panel a) predict the spatial probability of mammalian predation on wild turkeys (panel b) using Mahalanobis distance factor analysis in Quitman County, Mississippi, United States. The three habitat fragmentation variables are represented by three arrows, respectively.
