Evaluating protected areas’ coverage of threats to terrestrial biodiversity
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Protected areas (PAs) are vital for biodiversity conservation and have expanded globally. However, increasing pressures on biodiversity make it difficult to achieve conservation goals. Using threat probability maps based on the International Union for Conservation of Nature Red List and the World Database of Protected Areas, we analyzed the ...

People and Nature, Volume 7, Issue 11, Page 2700-2713, November 2025.Abstract Large old trees are important ecological entities in human settlements, providing cultural values and ecological services that are threatened by current and future changes in global climate, land use and disturbance regimes. Some studies suggest incorporating social and cultural significance into the conservation of large old trees.

Hydro‐Insurgency: Weaponization of Water Resources and Infrastructure in Northeast Syria
World Water Policy, Volume 11, Issue 4, Page 924-938, November 2025.ABSTRACT This article examines the strategic weaponization of water resources by Turkey‐backed armed groups in Northeast Syria (NES) within the broader context of the Syrian civil war. As the conflict evolved, water infrastructure—dams, rivers, and irrigation systems—became central to warfare, governance, and foreign agendas. The article introduces the

1985-2020年天水市黄土区滑坡灾损土地利用时空变化特征
Shuitu Baochi Xuebao, 2023 为探索甘肃省天水市滑坡土地利用特征及时空变化规律,选取秦州区和麦积区作为典型黄土滑坡区的代表,基于12.5 m分辨率的ALOS DEM数据和1985—2020年全球30 m的精细地表覆盖动态监测产品,利用GIS空间分析、土地利用净变化量指数、土地利用转移矩阵和土地利用贡献率,分析滑坡体的特征参数、土地利用/覆被类型、土地利用转移特征及驱动因素。结果表明:(1)研究区共识别出469个滑坡样本,平均高程集中于1 200~1 400 m,平均坡度10°~15°,平均坡向为西向坡,前后缘相对高差100~150 ...
