AbstractThe study investigated the role of boring polychaetes in the bioerosion of a submerged Roman mosaic floor in the Underwater Archaeological Park of Baiae (Naples, Italy). Three boring species, Dodecaceria concharum, Polydora ciliata, and Pseudopolydora antennata, were found. The initial colonization phases of boring polychaetes were investigated on experimental limestone panels placed underwater in the same marine area. The results showed that the ecological succession was characterized by a first stage of colonization with abundant spionids and a second stage with a boring mature community dominated by D. concharum. The study of silicone casts of the bored traces allowed confirmation that the ichnospecies belonging to the ichnogenera Maeandropolydora could be attributed to the action of spionid worms, whereas D. concharum is able to produce tongue- and ribbon-shaped borings (ichnogenus Caulostrepsis), and variously contorted galleries (ichnogenus Maeandropolydora) by settling inside borings produced by other polychaetes and increasing the complexity of the gallery system by modifying them. The study of the epilithic polychaete community highlighted that the site is characterized by a low hydrodynamism. Therefore, the most suitable in situ preservation interventions would be the covering of the mosaics with sand layers or geotextiles.

多毛类在 Baiae 水下考古公园（意大利那不勒斯）水下马赛克地板生物侵蚀中的作用

摘要本研究调查了在 Baiae 水下考古公园（意大利那不勒斯）沉没的罗马马赛克地板的生物侵蚀中钻孔多毛类动物的作用。发现了三种无聊的物种，Dodecaceria concharum、Polydora ciliata 和 Pseudopolydora 触角。在同一海域水下放置的实验石灰石板上研究了钻孔多毛类动物的初始定殖阶段。结果表明，生态演替的特点是第一阶段定植有丰富的棘球藻，第二阶段为枯燥的成熟群落，以 D. concharum 为主。对无聊痕迹的硅胶模型的研究证实了属于 ichnogenera Maeandropolydora 的鱼类物种可归因于 spionid 蠕虫的作用，而 D. concharum 能够产生舌状和带状钻孔（ichnogenus Caulostrepsis）和各种扭曲的画廊（ichnogenus Maeandropolydora），通过在其他多毛类动物产生的钻孔内定居并通过修改它们来增加画廊系统的复杂性。对附生多毛类群落的研究强调，该地点的特点是水动力低。因此，最合适的原位保护干预措施是用砂层或土工布覆盖马赛克。对附生多毛类群落的研究强调，该地点的特点是水动力低。因此，最合适的原位保护干预措施是用砂层或土工布覆盖马赛克。对附生多毛类群落的研究强调，该地点的特点是水动力低。因此，最合适的原位保护干预措施是用砂层或土工布覆盖马赛克。
