Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

在28 ℃、(28 ±3) ℃和(28 ±6) ℃温度条件下孵化乌龟(Chinemys reevesii)卵,检测上述温度条件对孵化期、孵化成功率、幼体大小以及运动能力的影响.孵化温度显著影响乌龟卵的孵化期、幼体重量和背甲大小,但对孵化成功率和幼体运动能力无显著影响.恒温条件下卵的孵化期短于波动温度,恒温条件下孵出的幼体体重大于波动温度条件下的幼体.因此,与恒温相比,波动孵化温度并不提高乌龟幼体质量.

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.
