Differentiation of the Canada lynx, Felis (Lynx) canadensis subsolana, in Newfoundland
1975 Canadian Journal of Zoology (53): 699-705
Cranial measurements, standard measurements, weights, and pelage color of the lynx from Newfoundland (Felis canadensis subsolana) and the North American mainland (F. c. canadensis) were compared to assess the difference between the two forms. Of the nine bivariate cranial relationships investigated, five (zygomatic width, mastoid width, interorbital width, postorbital width, and width between the postorbital processes) were found to be significantly greater relative to condylobasal length in F. c. subsolana. Overlap in variation between the two forms is considerable, however, Standard measurements and weights do not differ significantly. In addition, F. c. subsolana has a somewhat darker pelage than the mainland form. The isolation of the insular form may be of relatively recent date, as it has diverged only slightly from mainland populations and its recognition as a separate subspecies is questionable.
