^****James D. Reist is a Research Scientist at Fisheries and Oceans Canada who investigates the biodiversity of northern fishes including taxonomic, life history and ecophenotypic variation, particularly of chars, ciscoes and whitefishes. In addition to investigating natural drivers such as ecosystem complexity which affect fish diversity at these levels, he also researches the consequences of anthropogenic stressors such as climate change and habitat changes on the diversity and the implications of such for aquatic ecosystems and humans. His address: Fisheries and Oceans Canada, 501 University Crescent, Winnipeg, MB, R3T 2N6, Canada. Jim.reist@dfo-mpo.gc.ca
