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

Shuitu Baochi Xuebao, 2004 以黄土丘陵区纸坊沟流域为研究区,对其60年来的土地利用格局变化进行系统的分析研究,结果表明,土地利用格局变化与人类活动密切相关。农业用地的扩张,是导致林草植被破坏和土地利用格局变化的重要原因。从1938～1958年,坡耕地在土地利用格局中的优势度由低到高,而林草植被的优势度则降至最低点。之后,林草植被随着坡耕地的变化经历了缓慢变化期(1958～1973年)和较快增长期(1973年后)。其中1958年和1995年,是土地利用格局的质变点,也是生态环境变化的重要转折点 ...

Global Change Biology, Volume 31, Issue 11, November 2025.This study assessed the potential impacts of climate and land‐use change on soil fungal diversity across four North American biomes. We found that climate change typically caused both diversity losses and gains, particularly in coniferous forests and among arbuscular mycorrhizal fungi, whereas land‐use change mainly reduced diversity, especially in ...

Shuitu Baochi Xuebao, 2006 秦岭地区是中国南北自然环境的天然分界线，是我国自然环境特征形成的一个重要组成部分。利用RS和GIS技术，分析了近20年来秦岭地区土地利用／土地覆盖在数量、结构、类型和空间分布上的变化情况。并对土地利用／土地覆盖变化的驱动力作了进一步探讨，得出以下结论：20年间秦岭地区土地利用／土地覆盖变化林地、草地和建设用地呈增长趋势，耕地、水域和未利用地则呈减少趋势，林地基本呈稳定状态，增幅仅为0．70％，但增加和减少的面积均较大；耕地减少的幅度较大。减幅为158838．02hm^2。主要转变为林地、草地和建设用地 ...
