My research program is designed to serve conservation goals by illuminating the evolutionary processes that generate biodiversity. In terrestrial systems, populations are usually defined by discontinuous fragments of habitat. These populations may eventually develop intrinsic reproductive barriers, the starting point for speciation. Hence habitat discontinuities may explain most cases of speciation on land, but what about speciation in the sea, where few such barriers exist? In the sea, the evolutionary rules may be different, or they may operate on a vastly different scale due to the connectivity of a trans-global aquatic medium.
My research goals include:
- resolve the life history traits (especially dispersal ability and habitat specificity) that influence dispersal and population separations in Pacific reef organisms.
- test evolutionary models for how biodiversity is generated in the sea, including predictions for allopatric speciation, the center of accumulation hypothesis, and the center of origin hypotheses.
- expand and refine the library of nuclear introns available for population genetic studies of marine fishes and other aquatic organisms.
- provide phylogeographic surveys in the service of marine conservation, particularly to define management units and to assist the design of marine protected areas.
