An application of factor analysis in an aquatic habitat study. Harshbarger, T. J. Pages 180-184 in D, 1981.
Paper abstract bibtex In five small, high-gradient trout streams in western North Carolina, 18 cover variables were related to standing crop biomass of wild brook trout (Salvelinus fontinalis), rainbow trout (Salmo gairdneri) and brown trout (Salmo trutta). Factor analysis showed that only a few factors or variables were needed to explain relations between variables in the observed set. Key cover factors were area in debris; turbulent water; vegetation in and over stream; and overhanging banks. Resolutions obtained were used to explore relationships between standing crop of trout and age of fish.
