野生动物学报, 2022 以分布在不同海拔(2 279、3 273、4 452 m)的喜马拉雅旱獭(Marmota himalayana)为供试材料,通过二代测序技术对线粒体基因组序列进行比较分析,挖掘喜马拉雅旱獭低氧适应相关基因。结果表明:不同海拔喜马拉雅旱獭线粒体序列长度之间并无差异,但蛋白质编码基因突变位点个数随海拔增加而增多,ND5基因的突变位点个数和非同义突变位点个数都为最多,其Ka/Ks>1,表明ND5基因存在正选择效应,可作为适应高海拔低氧环境的候选基因。与玉树(海拔4 452 m)相比,乐都(海拔2 279 m ...

, 2017 目的:考察高海拔缺氧对注意网络影响的时间效应。方法:采用队列设计,追踪测试23名首次进入高海拔地区(3650米)大学生的注意网络,三次测试分别完成于驻留一周、一个月和两年。结果:注意网络中的执行控制功能受高海拔影响的时间效应显著。驻留一个月后执行控制功能比一周时显著上升,驻留两年后的执行控制功能比一个月时显著下降,但仍显著高于驻留一周时。警觉和定向功能的时间效应不显著。结论:高海拔驻留时间影响执行控制功能,一周和两年比一个月时显著下降,推测其随驻留时间延长呈现出先下降、后恢复、再下降的变化趋势。

Plant invasion in mountain ecosystems reduces soil micro‐food web complexity at higher elevations
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Anthropogenic activities have accelerated plant invasions in mountain ecosystems, impacting the structure and functions of native plant communities. Changes in above‐ground vegetation can drive shifts in below‐ground biota, yet the effects of plant invasions on soil ...

Integrative Conservation, Volume 5, Issue 3, Page 281-292, September 2026.We comprehensively evaluated the seed plant diversity of Jiangxi province to address the regional biodiversity conservation of Asian subtropical evergreen broad‐leaved forests (EBLFs). Higher species diversity of seed plants was observed in eastern, southern, and western Jiangxi, with elevation and precipitation as mainly environmental factors.

Phenology drives asymmetric responses of ecosystem productivity stability to warming and cooling
Functional Ecology, Volume 40, Issue 9, Page 2959-2971, September 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem productivity stability is a key indicator of ecosystem functioning under climate change, but the role of cooling periods in increasingly variable climates remains poorly resolved.

, 2020 桑寄生植物(桑寄生科)的分布与寄主选择性和生境相关。本研究沿海拔梯度(175～3106 m)设置3条样带共292个样方(20 m×20 m),调查了鄂西亚热带森林群落中桑寄生的分布,记录桑寄生植物多样性。结果表明:在研究区内共调查到7种桑寄生科植物,40种寄主植物;桑寄生植物分布的最低海拔是194 m,最高海拔是2011 m;物种多样性在海拔梯度上先上升后下降,相对集中分布在海拔600～1000 m范围内,呈现单峰分布格局;不同桑寄生科植物在不同寄主植物上的寄生强度不同,更偏好选择高大的落叶乔木作为寄主;

Journal of Ecology, Volume 114, Issue 8, August 2026.Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

Climbing to survive: Potential elevational shifts in warming risk for the Moltrecht's treefrog
Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.Low‐elevation populations of Zhangixalus moltrechti had higher thermal limits but lower warming tolerance than high‐elevation populations. Climate change is expected to expand high‐risk areas upslope, highlighting the need for emissions reduction and targeted habitat management.

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 ...
