Wildlife Letters, EarlyView.Tracking with GPS and accelerometers shows that great evening bats in subtropical China use two overwintering strategies: some remain in continuous hibernation, while others switch between torpor and activity as temperatures change. This behavioral flexibility, shaped by climate, underscores the importance of protecting diverse roosting habitats for ...

Wildlife Letters, EarlyView.Human‐caused leopard deaths in Sri Lanka averaged 9.65 ± 4.5 records year−1 over 17 years (2008–2024; n = 164), with records highly clustered in the central highland mosaic ecosystem. Mortality was dominated by adult males and driven primarily by snaring in plantation landscapes, and indicating an increase approximately 0.7–0.8 deaths per year.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Most terrestrial plant species form symbioses with arbuscular mycorrhizal fungi (AMF). However, the below‐ground carbon (C) allocation of plants and the nutritional and growth benefits provided by AMF within this symbiosis vary greatly across species and environments ...

Dianci bileiqi, 2022 直流系统避雷器组伏安特性的差异会使电流分配不均,伏安特性较差的避雷器加速老化,甚至被击穿,引发严重的安全问题。氧化锌阀片均能配组能够有效减小各避雷器柱的伏安特性差异,缓解电流分配不均匀的问题,提高避雷器组保护性能。提出了基于正态分布规律的氧化锌阀片均能配组方法,将能量吸收差异最大的两柱避雷器中吸能差异最大的电阻片对调,并多次迭代,实现避雷器组各避雷器柱的电流不均匀系数最小。通过对64柱每柱54片氧化锌阀片进行配组研究,结果表明 ...
