摘要

在过去三十年中,地中海多个地区 Astrospartus mediterraneus(Risso,1826 年)的出现率和丰度显著增加。在 Tavolara-Punta Coda Cavallo 海洋保护区(撒丁岛东北部、第勒尼安海、地中海),主要在 Tavolara 海峡的花岗岩滩涂上观察到 60 个标本,该地区的特点是水流非常湍急,沉积物较多。篮子星主要以珊瑚虫(Eunicella verrucosa、Paramuricea clavata 和 Leptogorgia sarmentosa)和大块海绵(Spongia officinalis、S. lamella、Sarcotragus foetidus)附生体的形式生活。我们还记录了 2024 年 6 月在 E. verrucosa 和 P. clavata 聚落的 27 至 52 米深处观察到的 21 个小标本(口盘直径 3 至 20 毫米)。这些标本的大小-频率的双峰分布表明,这些标本可能属于 2023 年春季和 2024 年春季发生的两次不同的繁殖活动。

Recruitment of the Basket Star Astrospartus mediterraneus (Risso, 1826) (Ophiuroidea, Gorgonocephalidae)
The occurrence and abundance of Astrospartus mediterraneus (Risso, 1826) have significantly increased in the last three decades in several areas of the Mediterranean Sea. In the Tavolara–Punta Coda Cavallo Marine Protected Area (NE Sardinia, Tyrrhenian Sea, Mediterranean Sea), 60 specimens were observed mainly on the granitic shoals of the Tavolara Channel, an area characterized by very intense currents and high sedimentation. The basket stars were mainly found living as epibionts of gorgonians (Eunicella verrucosa, Paramuricea clavata and Leptogorgia sarmentosa) and massive sponges (Spongia officinalis, S. lamella, Sarcotragus foetidus). We also documented 21 small specimens (3–20 mm in diameter of the oral disc) observed in June 2024 between 27 and 52 m depth on E. verrucosa and P. clavata colonies. The bimodal size-frequency distribution of these specimens suggested that, probably, specimens belong to two different reproductive events occurring in spring 2023 and 2024.
