Environmental stress in Parnassius apollo reflected through wing geometric morphometrics in a historical collection with a possible connection to habitat degradation


	Breakpoint regression analysis of the CV1 for the fore- and hind wing displaying the estimated breakpoint of the forewing CV1 in 1960 (se = 0.0058, Pr(>F) = 6.42×10-8) and for the hindwing in 1960 (se = 0.0051, Pr(>F) = 0.00511).
