Phenotype response for the invasive <i>Petaurus notatus</i> in Tasmania.

ABSTRACT: A mainland native nocturnal arboreal glider Petaurus notatus (Krefft's Glider) was introduced to Tasmania in the 1830s as a pet and its subsequent escape and landscape spread has been associated with the predation of endemic and migratory birds. Using geometric morphometrics, we assessed whether P. notatus experienced a phenotypic response, visible in their skull, after introduction to Tasmania. We found significant skull form variation between Tasmanian (n = 57) and Victorian (n = 102) glider specimens. Specifically, there is an increase in rostrum length-particularly at the mid-cranium-a dorsal shift of the frontal bones, and increase in posterior angle of the coronoid process on the mandible. Whether this morphological change is associated with a dietary shif
