世界最高树木吸碳能力超估算
世界 最高树木 吸碳能力 超估算
2020/10/19
美国和英国研究人员用激光测量后发现,世界最高树木重量远高于原来估算,吸收的碳元素也比原来估算多。据英国《泰晤士报》16日报道,英国伦敦大学学院和美国马里兰大学研究人员用激光测量美国加利福尼亚州北部生长的红杉后得出上述结论。红杉是世界上最高的树种。研究人员测量发现,一株名为“阿姆斯特朗上校”的老红杉高88米、重110吨,而原来估算重量是70吨至90吨。与先前测量技术相比,激光测量结果更准确。

世界上最古老的树木也非长生不老(图)
世界上 最古老 树木 长生不老
2020/7/28
地球上最古老的树木已经屹立了近5000年,研究人员一直想知道这些古老的生物会在多大程度上衰老、机体会如何随年龄的增长而退化。最近发表的一篇研究世界上最长寿树木之一银杏树的论文甚至发现,银杏树或能“在整个植物层面上避免衰老”,这就提出了一个问题,即百年老树明显没有衰老。然而,7月27日发表在Cell Press细胞出版社旗下期刊 Trends in Plant Science(《植物学趋势》)上的文...

海平面上升威胁红树林(图)
海平面上升 红树林
2020/6/8
近日,一项新研究分析了全新世冰川消退对红树林生长的影响,让人们得以一窥生态系统将如何应对未来迅速上升的海平面。澳大利亚麦考瑞大学、美国罗格斯大学等机构研究人员在《科学》杂志上发表论文称,如果温室气体排放不减少,到2050年,红树林将无法承受海平面上升之重。红树林主要分布在温暖气候地区,是宝贵的沿海生态系统。红树林储存了大量的碳,有助于保护海岸线,为鱼类和其他物种提供栖息地。研究人员利用过去1万年的...
