Monster Seminar JAM - Local adaptation and thermal tolerance in adult migrating Fraser River sockeye salmon populations

Presentator(s):
Erika Eliason

Long Description:
Every year, millions of sockeye salmon return to the Fraser River (BC, Canada) to perform their once-in-a-lifetime upriver spawning migration. There are over 100 geographically and genetically distinct populations within the Fraser River watershed, each of which experiences unique upriver migration conditions varying in migration distance (100-1,100 km), elevation gain (10-1,200 m), river temperature (9-22°C) and river flow (2,000-10,000 m3 s-1). Climate change-induced increases in summer river temperature have been associated with exceptionally high mortality in migrating salmon, raising conservation concerns. This research examined thermal tolerance and local adaptation across sockeye salmon populations over several levels of biological organization, from whole animal swimming and cardiorespiratory performance, organ performance, gross organ morphology, ultrastructure and receptors. Fraser River sockeye salmon populations appear to have physiologically adapted to their local upriver migration environment. In addition, some populations may be more susceptible to continued river warming, which has clear conservation concerns for biodiversity.

More Information:
Throughout the last decade, I have conducted research at 7 different institutions in 6 countries (Canada, Australia, England, Norway, Puerto Rico, Fiji), studying topics as diverse as bark beetle communication, coral reef conservation and sexual behavior in monkeys before concentrating on fish physiology. My current research interests focus on understanding the underlying physiological mechanisms of ecological phenomena and conservation problems. Specifically, Ive been studying temperature tolerance and local adaptation using adult migrating Fraser River sockeye salmon as a model.
