Fig. A3. Principal Component Analysis (PCA) of fatty acids of 79 Lake Trout classified as piscivorous morph from Great Bear Lake, based on the proportions of 41 fatty acids in dorsal muscle tissue. Spatial variations (5 arms; 1=Keith, 2=McVicar, 3=McTavish, 4=Dease, and 5=Smith) are represented, based on the fatty acids profile of each lake trout analyzed in this study.
