Resource selection functions for age-0 Arctic grayling ( Thymallus arcticus ) and their application to stream habitat compensation
We developed resource selection functions (RSFs) for young-of-the-year (YOY) Arctic grayling (Thymallus arcticus) in a natural Barrenlands stream and used them to assess the habitat in an artificial stream created as part of a habitat compensation agreement in the Canadian Arctic. The model for smal...
