Shape differences among populations of the four study lakes a) Results of CVA using
geometric morphometric data to test for body shape differences among populations. Bivariate plot show variation along the first two major axes of shape variation (canonical
variates 1 and 2,% of predicted variance in brackets). b) Warped outline drawing (derived from thin-plate spline method, amplified by 250%
to facilitate visualization) depict shape differences of fish from DÃ¶llnsee (black
line), compared to the average shape of all fish (grey line). Positions of the 14
digitized landmarks used in geometric morphometric shape analysis are shown. 1: anterior
tip of snout; 2: anterior margin of eye; 3: posterior margin of the eye; 4: dorsal
margin of opercular (principal opercular bone); 5: ventral margin of opercular (principal
opercular bone); 6: posterior margin of operculum; 7: posterior insertion of dorsal
fin; 8: anterior insertion of dorsal fin; 9: superior insertion of caudal fin; 10:
inferior insertion of caudal fin; 11: anterior insertion of anal fin; 12: posterior
insertion of anal fin; 13: insertion of pelvic fin; 14: anterior insertion of pectoral
fin.
