Ecological features of upriver migration in Kitakami River chum salmon and their connection to aerobic thermal performance.

ABSTRACT: The physiological performance of ectotherms is influenced by temperature, raising concerns about the impact of global warming on ectotherms. Understanding the relationship between ecologically relevant temperatures and the physiological performance of ectotherms provides a basis for assessing their resilience to changing environments. Absolute aerobic scope (AAS) is a functional metric of the thermal performance of aquatic ectotherms. The thermal profile of chum salmon (Oncorhynchus keta) returning to the Kitakami River, Japan, in early October has already been explored in a previous study; however, the ecological aspects of their upriver migration (e.g. spawning site, migratory duration and experienced temperature) and their connection to AAS thermal profiles are not fully understo
