Dr. Dan MacGuigan, a postdoctoral fellow in the Krabbenhoft Fish Genomics Laboratory, was awarded an NSF fellowship to support his work examining how parallel genomic changes drive parallel morphological divergence both within and across species. MacGuigan's research focuses on parallel evolution in the fish fauna of the Carolina bays, an understudied series of freshwater lakes along the Atlantic coastal plain. These young lakes harbor several unique species plus replicate populations of the same species, providing a natural experiment to compare parallel evolution among versus within species.
Research in the Krabbenhoft Fish Genomics Laboratory is broadly focused on pattern and process in the evolution and ecology of fishes. Our work involves testing conceptual hypotheses and addressing applied issues related to the effects of climate change, invasive species, alteration of flow regimes, fishing pressure, and other anthropogenic impacts on aquatic systems. Much of our research involves the use of genomic technology and bioinformatic analysis to address these questions. This research has important management and conservation implications both locally for Great Lakes and more broadly for aquatic ecosystems globally.
