后代留在亲代附近或广泛分散的程度对于理解种群动态、进化和生物地理学以及设计保护措施至关重要。在海洋中，大多数表明短距离分散的估计是基于对分散的个体的直接生态观察，而间接的进化估计往往表明种群之间有更大的同质性。调和这两种方法以及它们在扩散问题上看似相互矛盾的观点一直是一项重大挑战。在这里，我们首次展示了幼虫传播的进化和生态测量可以通过使用两者来估计传播距离的分布而紧密一致。在巴布亚新几内亚金贝湾的橙色小丑鱼（Amphiprion percula）种群中，我们发现进化扩散核宽为17公里（95%置信区间：12-24公里），而一组详尽的直接幼虫扩散观察表明，核宽在两年内为27公里（19 - 36公里）或19公里（15-27公里）。这两种方法之间的相似性表明，生态和进化扩散核可以是等同的，并且可以克服直接和间接测量之间的明显分歧。我们的研究结果表明，谨慎应用的进化方法通常成本较低，可以广泛地应用于理解生命之树上的生态扩散。
The degree to which offspring remain near their parents or disperse widely is critical for understanding population dynamics, evolution, and biogeography, and for designing conservation actions. In the ocean, most estimates suggesting short-distance dispersal are based on direct ecological observations of dispersing individuals, while indirect evolutionary estimates often suggest substantially greater homogeneity among populations. Reconciling these two approaches and their seemingly competing perspectives on dispersal has been a major challenge. Here we show for the first time that evolutionary and ecological measures of larval dispersal can closely agree by using both to estimate the distribution of dispersal distances. In orange clownfish (Amphiprion percula) populations in Kimbe Bay, Papua New Guinea, we found that evolutionary dispersal kernels were 17 km (95% confidence interval: 12–24 km) wide, while an exhaustive set of direct larval dispersal observations suggested kernel widths of 27 km (19–36 km) or 19 km (15–27 km) across two years. The similarity between these two approaches suggests that ecological and evolutionary dispersal kernels can be equivalent, and that the apparent disagreement between direct and indirect measurements can be overcome. Our results suggest that carefully applied evolutionary methods, which are often less expensive, can be broadly relevant for understanding ecological dispersal across the tree of life.
