Landscape influence on Canis morphological and ecological variation in a Coyote-Wolf C. lupus x latrans hybrid zone, southeastern Ontario. Canadian Field-Naturalist 117(4): 591-600. The ecology of Coyote-Wolf {Canis latrans x C. lupus) hybrids has never fully been typified. We studied morphological and ecological variation in Canis within a region of Coyote-Wolf hybridization in southeastern Ontario. We assessed Canis mor- phology from standard body measurements and ten skull measurements of adult specimens and found that Canis in this region are morphologically intermediate between Algonquin Provincial Park Wolves (C lupus lycaon) and Coyotes, indicating a latrans x lycaon hybrid origin; however, there is a closer morphological affinity to latrans than lycaon. Analysis of 846 scats indicated dietary habits also intermediate between lycaon and Coyotes. We used a geographic information system (GIS) to assess spa
