2023/12/1
The effect of climate on tree growth has received increased interest in the context of climate change. However, most studies have been limited geographically and with respect to species. Here, sixteen...
Nonlinear Mixed Effect Model Used in a Simulation of the Impact of Climate Change on Height Growth of?Cyclobalanopsis glauca
RegCM downscaling climate sensitive tree species nonlinear mixed effect model height growth of tree tree species diversity
2023/12/1
Localized climate is sensitive to terrain, underlying surface material, building distribution, green coverage and CO2?emissions. The Regional Climate Model (RegCM) was used to make a statistical detai...
Climate Change Risks to Global Forest Health: Emergence of Unexpected Events of Elevated Tree Mortality Worldwide
global forests dynamic global vegetation models forecasting forest assessment remote sensing mortality mechanisms hotter drought
2023/11/30
Recent observations of elevated tree mortality following climate extremes, like heat and drought, raise concerns about climate change risks to global forest health. We currently lack both sufficient d...
Modeling Tree Growth Responses to Climate Change: A Case Study in Natural Deciduous Mountain Forests

2023/11/22
Climate change has significant effects on forest ecosystems around the world. Since tree diameter increment determines forest volume increment and ultimately forest production, an accurate estimate of...
植被是陆地生态系统的重要组成部分，在全球变化碳循环研究中扮演着重要的角色。物候变化和碳循环年际变化密切相关，是全球变化领域的一个研究热点。现有物候变化研究大多关注植被春季物候变化，如展叶期、开花期等，对秋季物候变化的机制分析略显滞后。中科院地理资源所吴朝阳研究员、葛全胜研究员等联合美国、欧洲国家的全球变化领域专家开展了北半球植被秋季落叶期物候响应干旱变化的研究。

自20世纪80年代以来，全球渔业捕捞量一直处于停滞状态，近55%的鱼类资源被过度捕捞。相反，全球鱼类消费量却呈现出持续增长的态势，从1960年代的人均消费10kg增加到2016年的20.4kg。全球食用鱼类产品的消费量年均增速达到3.2%，超过人口增长的速率（1.6%），也高于陆生动物来源的肉类消费增速（2.8%）。这很大程度上得益于水产养殖业的发展和贡献，据联合国粮农组织《2018年世界渔业和水...
