Global variation in the thermal tolerances of lamprey / by Joy Wade and Paul Grant.: Fs97-4/3266E-PDF

"The degree to which freshwater fishes are vulnerable to climate change is dependant on a species' tolerance to change, and the magnitude of the change. Freshwater fishes are often highly sensitive to their thermal environments, especially those that are range restricted, which limits dispersal ability to thermal refugia. Understanding the thermal tolerances for species is therefore necessary to determine their potential vulnerability to climate change, and inform potential conservation management decisions for species. Lamprey, which evolved hundreds of millions of years ago have a global distribution in both freshwater and marine habitats. Despite variation in distribution, climate change has been identified as potential threat across all species, yet the degree of that impact is not fully understood. This is particularly concerning for lamprey species already considered at risk of extinction, such as the Western Brook Lamprey, Morrison Creek population (Lampetra richardsoni) and the Vancouver Lamprey (Entosphenus macrostomus) in British Columbia, where nothing is known about the thermal tolerances of these species. A literature review was therefore conducted to understand thermal tolerances for lamprey globally. Despite their global distribution and evolutionary history the range of variation between species is fairly narrow and can be used to infer likely thermal tolerances for at risk lamprey in British Columbia"--Abstract, page iv.
