Abstract

The slipper limpet Crepipatella dilatata, native to Chile and Argentina, was introduced in north-western Spain in 2005 and since then has spread to the Galician and Cantabrian coasts. In this work, we provide the first molecularly validated record of an established population of C. dilatata in central Portugal (Aveiro), and of reproductive individuals (i.e. brooding females) of C. dilatata in the Mediterranean Sea, from three Italian mussel farms (in eastern Sardinia and northern Adriatic). DNA barcoding and phylogenetic analyses based on mitochondrial markers indicate that limpets from Italian farms belong to the C. dilatata ‘clade1’, whereas limpets collected in Aveiro cluster within the C. dilatata ‘clade2’. All these limpets share the same COI haplotypes with introduced populations from Galicia. The arrival of C. dilatata to Europe is undoubtedly due to transoceanic live mussel trade from southern Chile to Galicia. Mussel trade and farming are also the most likely drivers for the post-border dispersal of C. dilatata from Spain to Portugal and to Italy. Several countries have a potential role as a hub for the primary and secondary dispersal of slipper limpets towards and within Europe. This calls the attention for future research focused on assessing the current occurrence and ecological impact of established populations of slipper limpets within and nearby mussel farms along the eastern Atlantic and Mediterranean coasts.

欧洲引进南美洲纤毛跛足虫 Crepipatella dilatata：在东北大西洋的二次传播和地中海的首次记录

摘要原产于智利和阿根廷的拖鞋瓣蹼藻 Crepipatella dilatata 于 2005 年被引入西班牙西北部，此后蔓延至加利西亚海岸和坎塔布里亚海岸。在这项工作中，我们首次通过分子验证记录了葡萄牙中部（阿威罗）的C. dilatata种群，以及来自三个意大利贻贝养殖场（撒丁岛东部和亚得里亚海北部）的C. dilatata在地中海的繁殖个体（即育雏雌性）。基于线粒体标记的 DNA 条形码和系统进化分析表明，来自意大利养殖场的笛笠贻贝属于笛笠贻贝 "支系 1"，而在阿威罗采集的笛笠贻贝则属于笛笠贻贝 "支系 2"。所有这些褐藻都与加利西亚的引进种群具有相同的 COI 单倍型。毫无疑问，C. dilatata 来到欧洲是由于从智利南部到加利西亚的跨洋活贻贝贸易。贻贝贸易和养殖也很可能是导致C. dilatata从西班牙向葡萄牙和意大利跨境扩散的主要原因。有几个国家有可能成为瓣鳃舄的主要和次要向欧洲和欧洲内部扩散的枢纽。这就要求今后的研究重点放在评估大西洋东部和地中海沿岸贻贝养殖场内和附近已建立的舄卤种群的当前发生情况和生态影响。

期刊介绍： Marine Biodiversity is a peer-reviewed international journal devoted to all aspects of biodiversity research on marine ecosystems. The journal is a relaunch of the well-known Senckenbergiana maritima" and covers research at gene, species and ecosystem level that focuses on describing the actors (genes and species), the patterns (gradients and distributions) and understanding of the processes responsible for the regulation and maintenance of diversity in marine systems. Also included are the study of species interactions (symbioses, parasitism, etc.) and the role of species in structuring marine ecosystem functioning. Marine Biodiversity offers articles in the category original paper, short note, Oceanarium and review article. It forms a platform for marine biodiversity researchers from all over the world for the exchange of new information and discussions on concepts and exciting discoveries. - Covers research in all aspects of biodiversity in marine ecosystems - Describes the actors, the patterns and the processes responsible for diversity - Offers peer-reviewed original papers, short communications, review articles and news (Oceanarium) - No page charges
