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. specialized PAPOUASIE NOUVELLE GUINEE NOUVELLE BRETAGNE KIMBE BAIE 036 034 27 1 149-154 2017 0960-9822 https://www.documentation.ird.fr/hor/fdi:010068868 10.1016/j.cub.2016.10.053 0960-9822 [F B010068868] https://www.documentation.ird.fr/hor/fdi:010068868 https://www.documentation.ird.fr/intranet/publi/2017/02/010068868.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-03-02 2017-08-23 fdi:010068868 fre
