Abstract

The sponge fauna colonizing rhodolith beds from Ustica Island marine protected area was studied. Moreover, an inventory of the sponge species present along the island’s coasts was carried out for the first time. Analysis of rhodoliths trapped in nets used by local fishermen at two sites and data obtained from underwater video images were used to identify 25 sponge taxa, 22 of them at species level. The classes Demospongiae and Homoscleromorpha were present with 24 and 1 species, respectively. Most of the specimens were small-sized and represented by thick crusts or short erect branches. Few specimens were insinuating or excavating. Furthermore, qualitative sampling was performed on Ustica’s coralligenous formations, photophilous hard substrates and in marine caves, and the results obtained were added to the literature data. The overall checklist of sponges from Ustica encompassed 97 taxa, 90 named at species level, subdivided into 6 taxa of Calcarea, 3 of Homoscleromorpha and 88 of Demospongiae. Eleven of the species were endemic to the Mediterranean Sea, mainly concentrated on rhodoliths and in marine caves. This research adds a fundamental element to the knowledge of invertebrates associated with rhodoliths, and updates the checklist of sponges colonizing Ustica’s waters, facilitating its future monitoring.

从乌斯蒂卡岛海洋保护区(南第勒尼安海)周围的rhodolith床中发现海绵,并对岛上海绵动物群进行了全面盘点
研究了乌斯提卡岛海洋保护区rhodolith床上的海绵动物群。此外,还首次对该岛沿岸存在的海绵物种进行了清查。通过对当地渔民在两个地点使用的网中捕获的rhodoliths和从水下视频图像中获得的数据进行分析,确定了25个海绵分类群,其中22个属于物种水平。Demospongiae纲24种,homooscleromorphia纲1种。多数标本体积小,以厚皮或短枝直立为特征。很少有标本是暗示或挖掘的。此外,对Ustica的珊瑚状地层、喜光硬基质和海相洞穴进行了定性采样,并将所得结果添加到文献数据中。Ustica的海绵共包括97个分类群,其中90个分类群在种水平上被命名,再细分为钙形目6个分类群、同骨形目3个分类群和蠕形目88个分类群。其中11种是地中海特有的,主要集中在rhodoliths和海相洞穴中。这项研究为与rhodolith相关的无脊椎动物的知识增加了一个基本的元素,并更新了Ustica水域的海绵清单,便于未来的监测。
