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 ...

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 ...

Temperature Distribution Analysis of Wood Cutting Tool with Differential Method [PDF]
, 1972 切削中の木材切削工具の温度分布を実測することには種々の困難があるので, 理論的に温度分布を求める一方法を示した。すなわちいくつかの仮定を置いて作った温度分布に関する微分方程式を差分方程式に変換し, それをし緩法によって近似的に解いた。その結果, たとえば切削速度が40m/secの時, 定常状態において刃先の温度は500 ...

A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

野生动物学报, 2022 为进一步探讨鳄蜥（Shinisaurus crocodilurus）的生理性体温调节能力，2018年8月，以广东省罗坑自然保护区鳄蜥研究中心成体饲养池内的鳄蜥为研究对象，探讨鳄蜥在20.0~30.0 ℃时，调节体温（Tb）与环境温度（Te）的关系。结果表明：以2.5 ℃梯度变温时，鳄蜥的调节体温与环境温度呈正相关，升温时，Tb=0.533Te+13.084（F1，48=327.65，R2=0.872 ...

Conservation Biology, EarlyView.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

Shuitu Baochi Xuebao, 2020 为探究滴灌条件下水温与土温对覆砂土壤水热运移规律的影响，基于HYDRUS-2D构建了不同水土温度土壤水热运移数值模型，模拟分析了不同水土温度对覆砂土壤水分、温度动态变化的影响。结果表明：灌溉水温对土壤水热分布影响显著，随着温度升高，土壤湿润体内含水率减小，表现为35℃水温 < 20℃水温 < 5℃水温，灌溉水温对土壤剖面温度分布也有较大影响，表层0—15 cm范围内温度变化了5~10℃。相同水温条件下，随着土壤温度升高，土壤饱和导水率增大，湿润土体内体积含水率减小，表现为30℃土壤温度 < 15 ...
