接受海龟的中上层潜泳期这一观点的最初困难在于解释在公海中可以找到可靠的弓食物供应。当我后来认识到沉降流聚集并排列浮力物质(包括地表水域分散的食物来源)的汇合的普遍性和多样性时,这种不确定性就被消除了。因此,现在看来很清楚的是,幼年海龟以及其他上层生物生存的一个重要因素是:开放海洋动物群也是如此——是前沿的可达性;无生命碎片和任何漂浮的动物或植物将聚集在那里。这一新证据表明海龟失年生态的复杂性对其保护和管理具有重要意义。现在很明显,当在所谓的珠启动项目中释放幼小的养殖海龟时,应该非常谨慎地选择释放地点。应避免远离任何主要水流或其涡流的海岸。还必须避免汇聚栖息地可能携带大量污染物的释放地点。目前的工作结果表明,迫切需要进一步研究海龟的生命周期,特别关注其发育生态学。越来越多的证据表明,海龟的中上层阶段更加漫长,在此期间,幼海龟在越来越多的碎片和有毒废物入侵的前沿被动迁徙,这强调了海洋生物学家需要更好地了解漂流线栖息地的组织及其行为生态学。在完成这些关于漂流线的海洋学和生物学研究之前,我们注定对地球表面五分之三的生态组织一无所知。
An original difficulty in accepting the idea of a pelagic diwelopmental period for sea turtles was to explain bow food could be found in reliable supply in the open ocean The uncertainty that this introduced was removed when I belatedly came to appreciate the prevalence and diversity of convergences where downwelling gathers and aligns buoyant material, including the dispersed food mources of the surface waters. Thus, it now seems clear that an essential factor in the survival of young sea turtles–and of other elements of the epipelagic; open‐ocean fauna as well–is the accessibility of a front; where inanimate debris and any floating animal or plant will be gathered to.This new evidence of complexity in the lost‐year ecology of sea turtles has important implications for their conservation and management. It is now obvious that when young cultured sea turtles are released in so‐called bead‐starting projects, the release sites ought to be chosen with the greatest care. Shores located at a distance from any major current or its eddy ought to be avoided. It is also necessary to avoid release localities where the convergence habitat may carry heavy loads of pollutants.Results of the present work reveal an urgent need for further study of sea turtle life cycles, with special attention to their developmental ecology The growing evidence for a more protracted pelagic stage, during which the juvenile turtles are passive migrants in fronts that are increasingly invaded by debris and toxic wastes, emphasizes the need for a better understanding by marine biologists of the organization of the driftline habitat and the behavioral ecology of its occupants Until these studies of the oceanography and biology of driftlines are done, we are bound to remain peculiarly ignorant of the ecologic organization of three‐fifths of the surface of the earth.
