Applying this approach, it becomes possible to quantitatively evaluate the contribution of spatially explicit migration towards patterns of genetic structure observed in the field. To provide a concrete example, the model was used to examine genetic dispersal between coral reef patches of the Caribbean. Using generic life-history parameters, the model shows the formation of a strong genetic break between eastern and western patches, as well as the development of a gradient along the length of the Bahamian archipelago, corresponding with evidence previously collected for coral and fish species. The data also suggest that Jamaica and the Cayman Islands are important stepping stones between the reefs of the northern Caribbean (Hispaniola and the Bahamas) and the Mesoamerican Barrier Reef. The model provides an effective means of evaluating regional-scale genetic connectivity through time and identifying natural clusters of genetic exchange. specialized 036 082 33 3 597-606 2010 0906-7590 https://www.documentation.ird.fr/hor/fdi:010049650 10.1111/j.1600-0587.2009.06012.x 0906-7590 [F B010049650] https://www.documentation.ird.fr/hor/fdi:010049650 https://www.documentation.ird.fr/intranet/publi/2010/08/010049650.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2010-09-03 2017-08-23 fdi:010049650 fre
