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

Monitoring climate changes and habitat degradation in threatened species without negative impact to the populations can pose a considerable challenge. A rare chance to test the morphological response of wing shape and size to environmental factors on the mountain Apollo ( Parnassius apollo ) collected from 1938 to 1968 at a single location – Strečno mountain pass, N Slovakia presented itself in a historical collection. The canonical variate...
