CHINOOK SALMON USE OF SPAWNING PATCHES: RELATIVE ROLES OF HABITAT QUALITY, SIZE, AND CONNECTIVITY.

The article focuses on a study related to examining the habitats of chinook salmon in three subbasins of the Middle Fork Salmon River (MFSR) in Idaho. An information-theoretic method was used to select the best logistic regression models that linked habitat quality, size, and connectivity to the occurrence of the habitats of chinook salmon. The relationship between the population density of the salmon and habitat changes was also examined. It was found that most of the models were dominated by measures of habitat size and connectivity and habitat quality was of minor importance.
