在这一期的分子生态学中，Yamasaki et al.（2020）使用来自日本琉球群岛的Rhinogobius goby鱼的广泛采样的遗传数据来证明淡水形式从祖先的两栖形式的平行物种形成。然后，他们表明，生态系统的大小强烈地预测了两种形式之间的物种形成的概率跨越岛屿。在这样做的过程中，这项研究将种群水平的过程（微观进化）与大规模的生物多样性模式（宏观进化）联系起来，这是进化生物学中一个重要但未充分研究的环节。展望未来，我们可以在这项研究的基础上（a）更直接地确定地理，生态和历史因素如何影响物种形成过程的不同阶段，以及（B）了解从岛屿辐射推断的机制是否延伸到大陆上，那里的人口历史和环境状况可能更加复杂。
In this issue of Molecular Ecology, Yamasaki et al. (2020) use genetic data from extensive sampling of Rhinogobius goby fish across the Ryukyu Archipelago in Japan to demonstrate the parallel speciation of a freshwater form from an ancestral amphidromous form. They then show that ecosystem size strongly predicts the probability of speciation between the two forms across islands. In doing so, this study connects population‐level processes (microevolution) to broad‐scale biodiversity patterns (macroevolution), an important but understudied link in evolutionary biology. Moving forward, we can build on this research to (a) more directly determine how geographic, ecological and historical factors influence the different stages of the speciation process, and (b) understand whether mechanisms inferred from insular radiations extend to those on continents, where both demographic histories and environmental regimes are likely more complex.
