Comparative phylogeography in Fijian coral reef fishes: a multi-taxa approach towards marine reserve design.

Delineating barriers to connectivity is important in marine reserve design as they describe the strength and number of connections among a reserve's constituent parts, and ultimately help characterize the resilience of the system to perturbations at each node. Here we demonstrate the utility of...
