World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Bengaluru, a primary metropolitan centre in India, is currently grappling with the dual crises of urban flooding and severe groundwater depletion. These challenges are driven by rapid urbanization, which has seen built‐up areas increase from 42% to 86% over two decades, resulting in a dramatic loss of vegetation and wetlands.

Shuitu Baochi Xuebao, 2017 为了研究人工红壤坡面对超大雨强降雨的响应过程，利用人工模拟降雨系统和变坡土槽，分别采用140，160，190 mm/h的雨强和10°，15°，20°，25°的坡度，对经过简单人工处理的红壤坡面在超大雨强降雨条件下的产流产沙响应过程进行了试验。结果表明：经过简单人工处理的红壤坡面在140~190 mm/h超大雨强下的土壤侵蚀模数明显低于50~120 mm/h雨强下未进行相应处理的坡面，细沟发育较为缓慢，对坡面土壤的处理方式能够有效提高坡面的抗侵蚀能力。在同雨强下，随着坡度的增加，产流时间先延长后缩短 ...

Integrative Conservation, Volume 5, Issue 1, Page 59-73, March 2026.This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

Integrative Conservation, Volume 4, Issue 3, Page 334-338, September 2025.This study reports four rare events of spiders preying on vertebrates in the Xishuangbanna Tropical Botanical Garden, Southwest China. The predators included a giant golden orb‐weaver, huntsman spiders, and a wandering spider, while the prey consisted of a small bird, a blind snake, a gecko, and a tiny shrew.

Shuitu Baochi Xuebao, 2011 通过室内模拟降雨试验,研究了不同降雨条件下地面坡度对红壤坡面产流过程和侵蚀过程的影响,结果表明,红壤坡面起始产流时间随坡度的增加有所提前,但不明显,坡面起始产流时间的早晚主要受降雨强度控制;坡面径流量随雨强的增大而增大,随坡度的变化比较复杂,在雨强为50mm/h时,径流量随坡度的增加而减小,在雨强为75mm/h时,径流量随坡度的增加先增大后减小;不同降雨强度下各坡度的侵蚀产沙率都是在降雨初期急剧上升,随后以指数下降,形成一个向左倾斜的曲线。坡度对坡面侵蚀产沙的影响随雨强的增大而增强 ...

Multiple global change factors alter the scaling of nitrogen to phosphorus in alpine plants
Functional Ecology, Volume 39, Issue 8, Page 2044-2055, August 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometry and allometry of nitrogen (N) and phosphorus (P) reflect nutrient absorption and dynamic allocation by plants, and can be regulated by global change factors (e.g. nitrogen enrichment, climate warming and altered precipitation). Yet, how multiple global

Shuitu Baochi Xuebao, 2017 通过对降雨移动方向上不同雨强和降雨历时的研究，揭示移动降雨坡面产流产沙关系及其变化规律，采用2个降雨移动方向（沿径流向上和向下移动）、2个雨强（1.35，2.75 mm/min）和2个降雨历时（60，120 min）在室内进行模拟移动降雨试验，分析不同降雨移动方向、不同雨强和降雨历时坡面产流产沙特征。结果表明：（1）向上移动降雨，相同历时（相同雨强）条件下，大雨强（长降雨历时）初始产流时间为140 s（240 s），比小雨强（短降雨历时）提前165 s（65 s）。（2）向下移动降雨，雨强越大 ...
