Illustrated framework for assessing thermal impacts of life stages along a river. (1) First, the life stage-specific TPC model is run at each spatial–temporal location, with temperature as the input. (2) Based on known phenology, the total performance throughout the duration of the life stage is calculated. (3) Results are sampled from the phenology and spatial distributions to estimate performance at spatial–temporal locations where salmon are found, as opposed to the whole river throughout the year. (4) To compare life stages, performance is converted into a metric of survival (see text). (5) The above steps are repeated for each life stage, and thermal impacts on different life stages are compared.
