Background: Forest management faces a climate induced sh.ft in growth.potential and increasing current and emerging new risks. Vulnerability analysis provides decision support based on proj.ctions of natural resources taking risks and uncertainties into account. In th.s paper we(1) ch.racterize differences in forest dynamics under th.ee management scenarios,(2) analyse th. effects of th. th.ee scenarios on two risk factors, windth.ow and drough. stress, and(3) quantify th. effects and th. amount of uncertainty arising from climate proj.ctions on h.igh. increment and drough. ***: In four regions in north.rn Germany, we apply th.ee contrasting management scenarios and proj.ct forest development under climate ch.nge until 2070. Th.ee climate runs(minimum, median, maximum) based on th. emission scenario RCP 8.5 control th. site-sensitive forest growth.functions.

Uncertainty analysis sh.ws th. increasing variability of drough. risk proj.ctions with.time.

Compaction rates of sediments or volcaniclastic material are needed to reconstruct original th.ckness of a bed, wh.ch.in turn is required to reconstruct subsidence rates, sea-level rise, or in th. case of volcanielastic, th. location or direction of th. eruption site. Th. knowledge of compaction rates can also aid in th. reconstruction of deformed fossils. Th. known sh.pe of deformed fossils can allow th. determination of th. compaction th.y experienced. h.re we report th. compaction rate in an early Permian volcanic tuff from Wuda, Inner Mongolia, determined from th. deformation of standing tree fern stems of known anatomy. Th. compaction rate h.s been found to be 0.56 in th.s case, indicating th.t 44% of original th.ckness remains.

急性戊型肝炎在我们地区是一罕见疾病,多地方性流行于第三世界国家,特别是印度、东南亚、中非、中美国家,由于旅游交往也常在北美和欧洲见到个别的病例。急性戊型肝炎病毒感染的病死率平均为2％,在妊娠妇女升高至20％。这种粪-口传播的“非甲非乙型肝炎”最初于1955年报道,但在1990年方才对戊型肝炎病毒的基因组序列分析成功并得到确认。

随着科技发展,人类活动对地面基础设施、空间系统和太空飞行器等高科技设施的依赖性日益增强.然而,这些高科技设施却常常遭受着来自太阳活动、地震、大气和气候变化、地磁场变化,以及全球电场波动等多种危害的威胁.监测和了解这些危害,并减轻其影响,是21世纪重要的科学挑战之一.这些危害尽管形式不同,但是有一个共同之处是会在电离层和中高层大气这个地球空间环境的关键圈层留下自己的印记.国际子午圈计划是一项由中国科学院牵头的国际大科学计划,其目标是整合、部署和运行一个全球研究和监测网络,充分利用电离层和中高层大气的"显示屏"效果来追踪这些日地空间危害的踪迹.文章展示了国际子午圈计划全球观测系统所需的位置分布,即优先沿120°E~60°W大子午圈部署监测设备,实现对主要地理和地磁纬度变化的最佳覆盖,继而辅之以30°E~150°W的第二个子午圈来捕捉经度变化.而后简单地描述了中国子午工程,以及横跨中国、俄罗斯和美洲的一些国家在内的120°E~60°W大子午圈上的监测台站和设备.
