大洋底部多数为沉积物所覆盖,因此沉积物就构成了地球空间覆盖中最大的一个单一生态系统。虽然生活在沉积物表面和内部的微型、小型和大型海洋有机体中只有一小部分被描述过,而且很少有人试图对物种总数和生物地理分布进行统计,但对若干物种的比较全面的了解足以说明底栖有机体对生态系统主要过程有显著的影响。底栖有机体参与碳、氮、硫的循环,水体的演变,污染物的传播、积累、二次污染和迁移,以及沉积物的稳定性等过程。虽然对群体之间的联系和功能上的冗余水平知之甚少,但在群体内部还是可能存在大量冗余的。说明生物多样性对于海底系统参与生态系统功能来说是必要的证据很少,但鉴于它们之间联系了解很少,预测性知识也仅限于几个物种,所以目前还无法准确推断物种的减少如何影响这些功能和生态系统的健康。因此,"做最坏的打算"作为一种保险的方法是可行的,而且要尽量避免由于捕渔、污染、栖息地的破坏,非本地(外来)物种的引入和全球变暖所造成的物种和基因多样性的减少。同时,科学家们应充分利用当前蓬勃发展的科学技术和对生物多样性的高昂的兴趣,以提供关于底栖生物和生态系统过程的具体而全面的信息。
