Abstract

The first record of the kelp species Phyllariopsis brevipes in the Campania Region (Tyrrhenian Sea, South Italy) is here reported. The species has been observed in October 2021 in four sites along Sorrento Peninsula and Capri Island coast during scuba diving surveys. P. brevipes grew on living thalli of crustose coralline algae from 32 up to 55 m depth, occasionally forming dense aggregations with a maximum cover of about 0.2 m2. The DNA barcoding analysis on the basis of the cox1 gene supported the identification, with 98.36% of similarity between the sample collected in this study (NCBI accession number: PP622796) and a sequence obtained from a specimen from Provence, Mediterranean France (NCBI accession number: GQ368264). The study area can be considered a stepping stone for the species dispersion. The occurrence of P. brevipes can be related to upwelling and good water quality and the monitoring of its health status might be a sentinel of environmental changes.

那不勒斯湾 1987 年出现的 Phyllariopsis brevipes (C. Agardh) E.C. Henry & G.R. South

本报告首次记录了坎帕尼亚大区（意大利南部第勒尼安海）的海带物种 Phyllariopsis brevipes。2021 年 10 月，在索伦托半岛和卡普里岛沿岸的四个地点进行潜水调查时观察到了该物种。P. brevipes 生长在水深 32 米至 55 米的甲壳类珊瑚藻的活体藻体上，偶尔会形成最大覆盖面积约为 0.2 平方米的密集聚集。以 cox1 基因为基础的 DNA 条形码分析表明，本研究采集的样本（NCBI 编号：PP622796）与从法国地中海普罗旺斯的一个标本（NCBI 编号：GQ368264）中获得的序列有 98.36% 的相似性。该研究区域可被视为物种扩散的踏脚石。P. brevipes 的出现可能与上升流和良好的水质有关，对其健康状况的监测可能是环境变化的哨兵。
