Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, EarlyView.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 ...

Wildlife Letters, EarlyView.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 ...

Functional Ecology, EarlyView.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, EarlyView.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.

Field Study on Effects of Simulated Sea Level Rise on Main Processes of Organic Carbon in Kandelia obovata Mangrove Ecosystems [PDF]
, 2015 本研究以厦门曾营海岸三个不同高程样地的秋茄红树林为研究对象，在模拟海平面上升80cm红树林（SLR80cm）、模拟海平面上升40cm红树林（SLR40cm）以及对照红树林（SLR0cm，大约相当于福建九龙江口红树林的滩面高程），探讨海平面上升对秋茄（Kandeliaobovata，以前学名为Kandeliacandel）红树林生态系统主要有机碳过程的影响。 SLR80cm样地的植株矮小、林相稀疏，生长状况明显不如SLR40cm和SLR0cm样地。各样地植株的生物量以及年增量总体均呈现出SLR0cm ...

Functional Ecology, Volume 40, Issue 5, Page 1151-1164, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

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。

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 ...
