Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Studies have shown that organisms may adjust metabolic rates in response to thermal variability, highlighting metabolic plasticity as a key adaptive mechanism. Understanding the extent of metabolic plasticity of an organism is key to predicting its adaptation to climate

野生动物学报, 2018 气候变暖是全球气候变化最主要的表现形式。由于人类活动的影响,全球气候变暖已成为不可逆转的趋势,严重影响物种的生存和繁衍。大熊猫作为世界珍稀濒危物种中的旗舰保护种,具有扩散、繁殖能力低、食物单一、分布范围窄、生境破碎化严重等特点,对气候变化较为敏感,气候变化极有可能成为大熊猫新的生存危机。因此,掌握气候变化形势、科学认识气候变化对大熊猫的影响,对大熊猫的保护工作有重要的理论和现实意义。文章总结了目前气候变化对大熊猫影响的研究进展,提出了一些存在的问题及建议。目前,关于气候变化对大熊猫影响的研究初有成果 ...

Greenhouse gas emissions from croplands of China [PDF]
, 2003 China possesses cropland of 1.33 million km 2. Cultivation of the cropland not only altered the biogeochemical cycles of carbon (C) and nitrogen (N) in the agroecosystems but also affected global climate.

Success of restoration strategies in preventing extirpation of 2 critically endangered coral species
Conservation Biology, EarlyView.Abstract An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis), were severely affected.

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.

Cross-cultural Comparative Analyses of Media Texts: A Corpus-based Study of Articles About Climate Change from Five English Newspapers [PDF]
, 2016 全球气候变暖问题相比较而言难以被公众直接感知，大众媒体将相关信息传递给公众，起着桥梁纽带作用。进入21世纪，全球气候变暖问题持续升温，引起国际社会的普遍关注。各国科学界和政界都积极推动，力图提高公众的参与意识，共同应对全球气候变化带来的挑战。虽然气候变化可以被科学家和科技专业人员准确测度，但却难以被公众直接感知。不可否认，全球气候变暖问题对公众来说，往往捉摸不定、变化莫测。公众对其感触不深，认知不切。所以，科技专业人士和公众之间存在信息不对等问题。就该问题而言，媒体的作用极为特殊 ...

Conservation Biology, EarlyView.Abstract In the western United States, conservation practitioners are increasingly working with private landowners to restore habitat for North American beavers (Castor canadensis) and to use nonlethal mitigation techniques when beavers damage crops and infrastructure.

Shuitu Baochi Xuebao, 2004 通过野外调查和对2000年TM影像的解译，分析了研究区土地沙漠化的分布格局与发展态势，以及土地沙漠化造成的负面影响。从气候因子的时空分布与变化和人地关系两大方面，探讨了研究区土地沙漠化发生、发展的原因。结果表明，沙漠化土地在空间分布上，与春季风蚀气候因子分布范围不一致；沙漠化在发展的速率上，与三大气候因子的动态变化不一致。结论指出：近50年来，气候因子的时空变化不是研究区土地沙漠化的主要原因；人畜压力与环境容量严重失衡，研究区人地关系的管理上屡有失误，落后的生产、生活方式转变缓慢 ...
