Function Derivation
Landscape correlation; Published/Peer-reviewed data; Published/Non-peer-reviewed; Empirical data;
Transferability of Function
This function was developed and applied to Athabasca Rainbow Trout in Alberta foothills watersheds. The data comes from landscape correlation with Alberta native Rainbow Trout streams and is supported by values in the published literature. The function is species and range specific but could potentially be applied to other Athabasca Rainbow Trout populations with caution. It should not be applied to other populations or subspecies of Rainbow Trout, as the thermal preference of Athabasca Rainbow Trout is reported to be lower.
Source of stressor Data
Athabasca Rainbow Trout and Westslope Cutthroat Trout inputs were derived from modelled mean summer stream temperature (°C) provided by ALCES Online© within the spatial unit of interest (e.g., HUC 10 watershed).
Function Type
continuous
Stressor Scale
linear
