巨型冰川 冰川消退 南极岛屿
2020/3/6
2020年2月初,研究人员在南极西部的松岛湾首次发现了这一露出头的岩石。2月早些时候,在南极洲海岸附近进行的一次科学考察发现了一个没有出现在地图上的岛屿。这一发现表明,由于气候变化,南极洲的变化速度有多快。
Upending an evolutionary theory proposed in the 1950s, scientists have found that the groups of animals most resistant to extinction also contain the greatest ecological diversity –- their members per...

物种进化 海洋生物 多样性 成因
2020/3/3
美国夏威夷大学希洛分校生物系研究人员2月28日在《科学》杂志上发表了他们关于地球动物生物多样性模式的新研究,认为现代海洋中的动物多样性,可以由动物群体中较低的灭绝率来解释,而不是像之前预测的那样源于较高的起源率。“今天,海洋动物比地球生命史上的任何时候都更加多样化,我们一直在努力描述它们是如何变成这样的。”该研究通讯作者、生物学助理教授Matthew Knope告诉《中国科学报》。
