Featured Research: by Heather Dawson

Dawson, HA., and M.L. Jones. 2009. Factors affecting recruitment dynamics of Great Lakes sea lamprey (Petromyzon marinus) populations. J Great Lakes Res. 35:353-360.

In this paper, Heather Dawson and her colleague explore the population dynamics of sea lamprey, an important predator of fish species in the Great Lakes. They found that larval production of sea lampreys varies tremendously among streams and lake basins independently of other factors, and that spawning and/or larval habitat quality must play a critical role.

Heather recently became an assistant professor in the Wildlife Biology program (Biology Dept.) at the Univ. of Michigan-Flint. Her research program uses field, laboratory, and modeling techniques to study and predict impacts of species invasive to the Great Lakes. Heather is a native Michigander who enjoys fishing and the outdoors. She is dedicated to solving natural resource management problems, and doing her part to protect and enhance the fish communities of the Great Lakes.

Heather received a dual Ph.D. in Fisheries and Wildlife and Ecology, Evolutionary Biology, and Behavior from Michigan State University in 2007. She then worked as a fishery biologist from 2007-09 for the U.S. Fish and Wildlife Service in their sea lamprey control office located in Marquette, MI.
