摘要:
竿虾虎鱼(Luciogobius guttatus)隶属于拟虾虎鱼亚科(Gobionellinae),已知分布于中国沿海、朝鲜半岛和日本的岩基砾石质潮间带。日本学者发现竿虾虎鱼在日本沿海存在三个谱系,但在我国,针对竿虾虎鱼的研究仅限于形态测量和野外调查记录。基于线粒体DNA和核基因序列标记,本研究从系统发育和群体遗传两个角度,揭示竿虾虎鱼在我国北方沿海的隐存多样性与群体历史。结果表明,与日本分布的竿虾虎鱼对比,我国北方沿海分布的竿虾虎鱼存在以崂山为潜在屏障的偏南、偏北两个谱系,分别对应于日本沿海的谱系A和谱系C,缺少谱系B。本研究推测,末次冰期对竿虾虎鱼的有效种群扩张和群体的分化及扩散起到关键作用,且不同谱系对冰期气候变化的反应并不一致。本研究初步查明了中国北方沿海竿虾虎鱼的隐存多样性现状,为我国竿虾虎鱼的保护提供了分子依据。

Abstract:
The flat-head goby, Luciogobius guttatus, Gobionellinae, is an intertidal dweller in stony coasts of East Asia. Previous researches have shown that there were three lineages (A, B, C) of L. guttatus in Japanese archipelago. Available studies in China only focused on L. guttatus morphological measuring works and survey records. We studied the cryptic diversity of their counterparts in northern China. Results show that the latitudinal distribution of lineage A (southern) and lineage C (northern) was affected by Laoshan Mountain in Qingdao, Shandong. The last glacial maximum (LGM) was Likely to be a key factor promoting the expansion, recovery, and divergence of the populations of L. guttatus. However, the responses to the LGM were different in each lineage. The study rendered the molecular basis for the conservation of L. guttatus on the coasts in northern China.
