Effects of food resources on the fatty acid composition, growth and survival of freshwater mussels
Fig 3
Canonical scores plot derived from a discriminant analysis of the concentrations of 18 fatty acids in the foot tissues of Lampilis cardium and L. siliquoidea grouped by site in the St. Croix River during a 28 d in situ exposure.
Open and closed symbols are from juveniles deployed at riverine and lacustrine sites, respectively. The centroid for each 95% confidence region is denoted by a +.
