—Stressful water temperatures negatively affect physiological processes in fishes, yet evidence for how elevated temperatures influence population-level characteristics is rare. An 8-year field study of brook trout Salvelinus fontinalis in an unstratified Adirondack lake revealed that an aggregate measure of chronically stressful summer water temperatures strongly influenced brook trout populat...

Native fishes often face simultaneous threats from habitat fragmentation and invasion by nonnative trout. Unfortunately, management actions to address one may create or exacerbate the other. A consistent decision process would include a systematic analysis of when and where intentional use or removal of barriers is most appropriate. We developed a Bayesian belief network (BBN) as a tool for suc...

During the present century, a great deal of the earlier work has been confirmed and still further progress made in our knowledge of the problem. The application of iddine therapy in the prophylaxi s and treatment of goitre was commenced. In America in 1910 Marine found that goitre in brook trout could be prevented.by the administration of Iodine, subsequently he found the same, result to apply ...

Broad-scale patterns of genetic diversity for Brook Trout Salvelinus fontinalis remain poorly understood across their endemic range in the eastern United States. We characterized variation at 12 microsatellite loci 22,020 among 836 populations from Georgia, USA, to Quebec, Canada, western Great Lakes region. Within-population was typically lower southern Appalachian Mountains relative mid-Atlan...
