Abstract

Garfish Belone belone (Linnaeus, 1761) are distributed over a wide area covering all the East Atlantic coasts including the North and Baltic Seas and the entire Mediterranean basin. Researchers have presented different opinions regarding the presence of subspecies and endemic species of garfish due to certain morphological variations found in Mediterranean populations up to the current day. The purpose of this study is to clarify the taxonomic status of Belone euxini Günther, 1866, described as the Black Sea endemic by Günther (1866) and Belone acus Risso, 1827, described as the Mediterranean gar fish population by Risso (1827) with an integrative perspective. B. belone specimens were sampled from 12 localities in the North-Eastern Mediterranean. The congeneric Belone svetovidovi Collette & Parin, 1970, specimens were sampled at different locations in the Eastern Aegean Sea and included molecular analyses in order to determine the interspecific distance between Belone species. Detailed morphological description and genetics are provided for B. belone populations. Based on the results, it can be supported that the differences observed between B. belone populations are within the limits of intraspecific variation thus indicating that there are no distinct populations at the species level in the Mediterranean basin.

Belone 属（Belonidae）的特有性还是同义性？对地中海东北部种群的综合分析

石首鱼（Belone belone）（林奈，1761 年）分布在包括北海和波罗的海在内的所有东大西洋沿岸以及整个地中海盆地。由于地中海种群中的某些形态变异，直到今天，研究人员对鲶鱼亚种和特有种的存在提出了不同的观点。本研究的目的是以综合的视角澄清被 Günther（1866 年）描述为黑海特有种的 Belone euxini Günther，1866 年和被 Risso（1827 年）描述为地中海嘎鱼种群的 Belone acus Risso，1827 年的分类地位。Belone 标本取自地中海东北部的 12 个地点。同属的 Belone svetovidovi Collette & Parin, 1970 标本取样于东爱琴海的不同地点，包括分子分析，以确定 Belone 种间的种间距离。对 Belone 种群进行了详细的形态学描述和遗传学分析。根据研究结果，可以证明在 Belone 种群之间观察到的差异在种内变异的范围之内，从而表明地中海盆地在物种水平上不存在不同的种群。

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
