Relative Suitability of Use Functions for Juvenile and Adult Grayling (Thymallus arcticus) in Streams in Northern Alaska (DenBeste & McCart, 1986)
This research paper presents relative suitability-of-use functions for juvenile and adult Arctic grayling (Thymallus arcticus) in 23 streams across northern Alaska, using depth, velocity, and substrate type as key habitat parameters. The study demonstrates that juvenile grayling prefer depths of 0.65 m with zero velocity and fine substrates, while adults prefer greater depths of 0.80 m, with both groups showing clear correlations between habitat suitability function values and fish occupancy and density.
