Species diversity is necessary for the maintenance of sustainable fisheries because differential use of habitats can help buffer against unpredictable conditions. Therefore, an important first step to maintaining or restoring species diversity is describing extant...

Genetic diversity among Great Lakes cisco species: exploring taxonomic and population boundaries
Ciscoes (Coregonus artedi, hoyi, kiyi, zenithicus, and nigripinnis) once formed a diverse species flock in the Great Lakes. While several taxa appear to have been extirpated, those that remain are an important part of the Great Lakes food web. Deepwater forms (C....
Are there differences in larval and juvenile gene expression between hatchery and wild coregonids?
Management agencies are investigating best practices for coregonid (C. artedi and C. hoyi) culture, stocking, and broodstock development. However, before large scale production can begin, decisions about the sources of broodstock, culture practices, and stocking rates...
Building molecular tools for coregonine species identification
The larval phase of Coregonus spp. represent a bottleneck in year class strength that is not well understood in extant populations and could present an impediment for coregonine restoration efforts in the Great Lakes. The use of species-specific DNA sequences to...
Historical and contemporary genetic diversity of Coregonus species from Lake Michigan
Advancements in molecular biology methods have allowed researchers to analyze genetic variation in extinct or extirpated species where minuscule amounts of cellular material remain. Here for the first time, we have leveraged one of these methods -...
