深海热液喷口动物群在海洋深处数公里处的发现是20世纪海洋生物学的一项伟大成就。深海热液食物网并不直接依赖太阳能。排气口群落主要依赖于化能自养细菌和消费者之间的营养关系。一些特有类群适应了沿着山脊分布的不适宜居住的喷口环境。这些喷口群落起源于何处以及它们是如何分散的，是生态学家必须回答的重要问题。在这里，最全面的数据库收集有关深海热液动物群的统计分析，我们划定了六个主要的热液区在世界海洋，并确定相邻省份之间的七个可能的扩散途径。我们的模型表明，东太平洋海隆可能作为热液动物群的扩散中心发挥了关键作用。我们的数据驱动的结论将不得不通过系统发育研究进行测试，并通过对较少探索领域的调查来完成。(C)2009爱思唯尔有限公司保留所有权利。
The discovery of deep-sea hydrothermal vent fauna, kilometres deep in the oceans, is a great achievement of 20th-century marine biology. The deep-sea hydrothermal food web does not directly depend on the sun's energy. Vent communities rely primarily on trophic associations between chemoautotrophic bacteria and consumers A small. number of endemic taxa are adapted to the inhospitable vent environments that are distributed along ridge crests. Where these vent communities originated and how they dispersed are among the important questions ecologists must answer. Here, by statistical analysis of the most comprehensive database ever assembled about deep-sea hydrothermal fauna, we delineate six major hydrothermal provinces in the world ocean and identify seven possible dispersal pathways between adjacent provinces. Our model suggests that the East-Pacific Rise may have played a pivotal role as a centre of dispersal for the hydrothermal fauna. Our data-driven conclusion will have to be tested by phylogenetic studies and completed by surveys of less-explored fields. (C) 2009 Elsevier Ltd. All rights reserved.
