中国多刺鱼属物种的分布现状北大核心CSCD

多刺鱼属(Pungitius)隶属于刺鱼科(Gasterosteidae),广泛分布于北半球水体中。由于趋同进化和种间频繁的杂交,使得该属物种的系统发育关系和分类有效性仍然存在争议。本文简要梳理了多刺鱼属物种的分类沿革及分布情况,并对全球尤其是中国的多刺鱼属鱼类的系统发育关系和生物地理分布进行了验证。本文进一步证实了Wang等(2021)的研究结果:在中国可能存在4个多刺鱼物种,包括中华多刺鱼(P.sinensis)、短多刺鱼(P.kaibarae)、巴氏多刺鱼(P.bussei)和黑龙江多刺鱼(P.stenurus);其中,中华多刺鱼存在2个不同的谱系。本文也建议保护和管理部门在计划人工放流时应同时依据物种的分子鉴定结果,以便更科学和高效地进行多刺鱼属鱼类的人工放流和物种保护。

Distribution Status of Pungitius Sticklebacks in China

Pungitius sticklebacks (Gasterosteidae) widely distributed across the Northern Hemisphere. Phylogenetics relationships and taxonomic validity of different species and/or populations remain contentious due to convergent evolution and frequent hybridization among the Pungitius sticklebacks. Here, we briefly reviewed the taxonomic history and distribution of the genus Pungitius, and verified the phylogenetic relationships and phylogeography of the genus from around the world, especially from China. This paper further confirmed the findings of Wang et al. (2021), i.e., there may be four species of Pungitius sticklebacks in China, including P. sinensis, P. kaibarae, P. bussei, and P. stenurus, among which the P. sinensis has two different lineages. We also suggested conservation and management authorities dealing with sticklebacks should resort to molecular species identification when planning translocations in order to more scientific and efficient artificial release and protection of sticklebacks.
