In this study, our goal was to test whether typical vent/seep organisms harbouring symbionts or not, would be able to settle on organic substrates deployed in the vicinity of chemosynthetic ecosystems. Since 2006, a series of novel standardized colonization devices (CHEMECOLI: CHEMosynthetic Ecosystem COlonization by Larval Invertebrates) filled with three types of substrates (wood, alfalfa and carbonate) have been deployed in different types of reducing habitats including cold seeps in the eastern Mediterranean, a mud volcano in the Norwegian Sea, and hydrothermal vents on the Mid-Atlantic Ridge for durations of 2 weeks to 1 year. For all deployments, highest species diversities were recovered from CHEMECOLIs filled with organic substrates. Larvae from species associated with thiotrophic symbionts such as thyasirid, vesicomyid and mytilid bivalves, were recovered in the eastern Mediterranean and at the Mid-Atlantic Ridge. At the Haakon Mosby Mud Volcano, larvae of symbiotic siboglinids settled on both organic and carbonate substrates. Overall, novel colonization devices (CHEMECOLI) filled with organic substrates attracted both fauna relying on chemosynthesis-derived carbon as well as fauna relying on heterotrophy the latter being opportunistic and tolerant to sulphide.
在这项研究中，我们的目标是测试是否具有共生体的典型通风/渗出生物能够在化能合成生态系统附近的有机基质上定殖。自 2006 年以来，一系列新型标准化定植装置（CHEMECOLI：通过幼虫无脊椎动物进行化能合成生态系统定植）中填充了三种基质（木材、紫花苜蓿和碳酸盐），并在不同类型的还原生境中进行了部署，包括东地中海冷渗口、挪威海泥火山和中大西洋脊热液喷口，持续时间从 2 周到 1 年不等。对于所有的部署，从填充有机基质的 CHEMECOLIs 中回收的物种多样性最高。与硫营养共生体相关的物种的幼虫，如贻贝、蛤和贻贝，在东地中海和中大西洋脊被回收。在哈康·莫斯比泥火山，共生的 siboglinid 幼虫在有机和碳酸盐基质上定殖。总的来说，新型定植装置（CHEMECOLI）填充有机基质吸引了既依赖化能合成碳又依赖异养的动物，后者是机会主义的，对硫化物有耐受性。
