热液喷口和渗漏区动物群的研究由于位置遥远而费用高昂。鲸鱼瀑布，这被认为是有栖息地的条件，重叠渗漏生态系统，可以被用来作为一个模型系统，以探讨问题，如扩散策略的演变和主机和它们的共生微生物之间的相互作用。我们在瑞典峡湾的一具沉没在陆架深度的鲸鱼尸体上发现了鲸鱼坠落动物群，这与浅水渗漏环境中明显缺乏专门生物形成了对比。在瑞典研究地点发现的鲸鱼坠落动物群的代表包括细菌垫喂养dorvilleid环节动物和吃鲸骨的pogonophoran蠕虫Osedax mucofloris格洛弗等人，2005.我们正在水族馆中维持鲸鱼群的存活，这些研究的初步结果表明，O。mucofloris具有连续繁殖生活史策略。
The study of hydrothermal vent and seep fauna is associated with great costs due to the deep and distant locations. Whale-falls, which are thought to have habitat conditions which overlap seep ecosystems, may be used as a model system to explore questions such as the evolution of dispersal strategies and interactions between hosts and their symbiont microbes. Our discovery of whale-fall fauna at a whale carcass sunk at shelf depth in a Swedish fjord contrasts the apparent lack of specialized organisms from shallow water seep environments. Representatives of a whale-fall fauna found at the Swedish study site include bacterial mat feeding dorvilleid annelids and the whale-bone eating pogonophoran worm Osedax mucofloris Glover et al., 2005. We are maintaining whale-fall fauna alive in aquaria, and initial results from these studies suggest that O. mucofloris has a continuous reproduction life-history strategy.
