三刺刺鱼（Gasterosteus aculeatus）是研究从海洋栖息地向淡水栖息地过渡期间平行进化的遗传机制的非凡系统。尽管之前大多数关于刺鱼平行进化的研究主要集中在北美西北部太平洋和北欧的冰河后淡水种群，但我们最近使用日本刺鱼种群来研究地理上遥远的种群之间共同和独特的适应和物种形成特征。然而，尽管良好的系统发育对于任何进化和生态研究都是至关重要的，但我们目前缺乏日本三刺刺鱼的全面系统发育。在这里，我们对日本列岛的三刺刺鱼进行了系统发育分析。我们发现淡水殖民发生在多个波浪中，每个波浪都可能反映了不同的间冰期隔离。据估计，日本大陆中部地区一些最古老的淡水种群（hariyo 种群）在大约 17 万年前就在淡水中定居。下一波殖民浪潮可能发生在大约 10 万年前。几个人类引入种群的推断起源表明，引入主要来自附近的栖息地。我们还发现了与日本海刺鱼（Gasterosteus nipponicus）同域的三刺刺鱼的新栖息地。这些日本刺鱼系统在分歧时间和历史方面与北美西北部太平洋和北欧的刺鱼系统不同。日本群岛的刺鱼种群为研究历史和当代时间尺度的不同进化过程提供了宝贵的机会。
The three-spined stickleback (Gasterosteus aculeatus) is a remarkable system to study the genetic mechanisms underlying parallel evolution during the transition from marine to freshwater habitats. Although the majority of previous studies on the parallel evolution of sticklebacks have mainly focused on postglacial freshwater populations in the Pacific Northwest of North America and northern Europe, we recently use Japanese stickleback populations for investigating shared and unique features of adaptation and speciation between geographically distant populations. However, we currently lack a comprehensive phylogeny of the Japanese three-spined sticklebacks, despite the fact that a good phylogeny is essential for any evolutionary and ecological studies. Here, we conducted a phylogenomic analysis of the three-spined stickleback in the Japanese Archipelago. We found that freshwater colonization occurred in multiple waves, each of which may reflect different interglacial isolations. Some of the oldest freshwater populations from the central regions of the mainland of Japan (hariyo populations) were estimated to colonize freshwater approximately 170,000 years ago. The next wave of colonization likely occurred approximately 100,000 years ago. The inferred origins of several human-introduced populations showed that introduction occurred mainly from nearby habitats. We also found a new habitat of the three-spined stickleback sympatric with the Japan Sea stickleback (Gasterosteus nipponicus). These Japanese stickleback systems differ from those in the Pacific Northwest of North America and northern Europe in terms of divergence time and history. Stickleback populations in the Japanese Archipelago offer valuable opportunities to study diverse evolutionary processes in historical and contemporary timescales.
