沿着海底用拖网捕捞海鲜的渔船会不加选择地伤害海洋生物，并且破坏它们的栖息地。现在，一项新的研究表明，拖网渔船还可能破坏海底微生物清除沿海水域中过量营养物质的能力，从而加剧海洋污染。“这是第一篇研究拖网捕捞的实际生物地球化学效应的论文。”没有参与该研究的美国加州大学河畔分校海洋生物地球化学家Sebastiaan Van de Velde说，“整个研究的角度非常新颖。”

英国《自然》杂志11日发表一项生物学研究，美国科学家在海底以下750米处，发现了微生物群落。这一发现增进了人们对微生物“资源竞争”的理解，也为进一步探索极端环境下微生物的生存开辟了新途径。
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...

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》。

并非所有人都认为150年前的浮游生物标本是有研究潜力的宝藏。但这正是Lyndsey Fox在英国伦敦自然历史博物馆发现一批有孔虫时的想法。如今，这位金斯顿大学的微古生物学家和同事已经证明，英国皇家海军挑战者号1872年至1876年采集的有孔虫样本，对了解现代气候变化有重要帮助：它们的外壳比现在有孔虫的外壳厚76%，而现在有孔虫的外壳正在变薄。
