最新研究发现海底甲烷或导致再次生物大灭绝（图）
甲烷 生物灭绝
2011/7/26
北京时间2011年7月25日消息，据国外媒体报道，荷兰古生态学家最新研究成果表明，海底释放的甲烷将可能会导致地球上再次出现生物大灭绝。研究人员认为，根据2亿年前生物大灭绝事件的特点，生物大灭绝似乎比预想中更容易触发。
被誉为“化学生态学之父”的美国著名生物学家托马斯·艾斯纳（Thomas Eisner）因帕金森病并发症于2011年3月25日不幸逝世，享年81岁。1994年，因为“在昆虫行为和化学生态学领域的巨大贡献以及在生物多样性方面所作出的国际成就”，艾斯纳荣获美国科学最高荣誉——国家科学奖章。
瑞典斯德哥尔摩国际水资源研究所2011年3月22日宣布，美国环境科学家卡彭特（Stephen R. Carpenter）因其在湖泊生态系统研究领域作出的贡献获得2011年斯德哥尔摩水奖。卡彭特现任美国威斯康星大学麦迪逊分校动物学和湖沼生物学教授。斯德哥尔摩水奖评选委员会说，卡彭特通过结合理论模型和大型湖泊实验，不仅改变了我们对淡水环境以及人类和周围景观如何影响湖泊生态系统的看法，而且还帮助我们对如...
