Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, Volume 8, Issue 7, Page 2186-2199, July 2026.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

野生动物学报, 2022 季节性繁殖是哺乳动物在长期的进化过程中,为了应对外界环境的变化,选择合适的季节进行繁殖的行为。雄性哺乳动物在非繁殖季节表现为睾丸退化,精子发生的减数分裂过程受阻,进入繁殖季节性腺恢复,重新启动精原细胞的分裂和分化,这种季节性精原细胞分裂和分化与精子发生受到环境因子和多种体内激素的调节。就光周期信号分子——褪黑激素通过TSH-DIO2/DIO3-T3逆行通路和HPG轴—睾酮—视黄酸信号系统对雄性哺乳动物繁殖季节性调控的研究综述可知:褪黑激素通过调控HPG轴的功能促进精子的发生 ...

Journal of Animal Ecology, Volume 95, Issue 7, Page 1178-1193, July 2026.This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

Gaoya dianqi, 2003 季节因素将影响接地系统的安全性能。季节系数随冰冻季节形成的地表高阻层的电阻率及其厚度的增加而增加。在我国北方高寒冰冻地区接地系统的接地电阻季节系数可达3.0,接触电压和跨步电压季节系数可能达到10和5.4。在雨季形成的地表低胆层也有可能导致接触电压的升高。采用垂直接地极能减小接地系统的季节系数,起稳定接地系统安全性能的作用。

Functional Ecology, Volume 40, Issue 6, Page 1878-1891, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological communities are stressed by rapid and complex anthropogenic changes, threatening the persistence of biotic interactions and ecosystem functioning. Plant–pollinator communities, for instance, undergo structural transformations as a result of land‐use change ...

Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Prioritization in conservation is crucial for the development of efficient and effective decision‐making policies. For many decades, the importance of some species and their habitats has been assessed and applied in conservation legislation, but bats and their diurnal roosts have ofbeen overlooked.
