Brook Trout Behavioral Thermoregulation And Habitat Selection In A Small Michigan Coldwater Stream: Implications For Successful Management, Justin Emory Wegner
Brook Trout Behavioral Thermoregulation And Habitat Selection In A Small Michigan Coldwater Stream: Implications For Successful Management, Justin Emory Wegner
Masters Theses
Global warming and conversion of forests for urbanization, agriculture and mineral extraction are increasing water temperatures throughout Brook Trout’s range causing population declines; particularly in populations persisting in marginal habitats and in the southern limits of their distribution. The Brook Trout is an ectotherm that can cope with elevated water temperature by moving to coldwater refuge such as groundwater seeps, coldwater tributary confluences, and headwaters. Availability of coldwater refuge is vital for the survival of Brook Trout populations threatened by increasing water temperatures. I used radio telemetry to study the movement, habitat use, and behavioral thermoregulation of Brook Trout living …

Evaluating Foraging Habits, And Estimating Prey Consumption, And Growth Of Brook Trout In A Coolwater Michigan Stream, Graeme R. Zaparzynski
Masters Theses
Brook trout (Salvelinus fontinalis) are a cold water ectotherm whose native distribution includes most of eastern Canada, the upper Midwestern United States, and the eastern and mid- Atlantic United States as far south as Georgia. The native range of brook trout in the United States has been reduced as a result of interspecific interactions with introduced species, and anthropogenic land use changes that drive water temperature changes in many of their native watersheds. Anthropogenic land-use changes tend to increase thermal regimes of aquatic systems, affecting brook trout physiology and limiting them to colder, headwater reaches. The threat of …
