Figure 3

Principal components analysis of fatty acids in five mollusc species in Illinois. The data from 60 unique fatty acids projected onto the first two principal components (jointly accounting for 40.6% of the total variance in their fatty acid profiles). Asian clams (Corbicula fluminea, an invasive species) and the round pigtoe (Pleurobema sintoxia) form clusters, whereas the three-ridge (Amblema plicata), Wabash pigtoe (Fusconaia flava), and fat mucket (Lampsilis siliquoidea), have fatty acid profiles that form less distinct clusters with some overlap between individuals.
