Wolf carcasses were obtained from trappers across northwestern Ontario between 1995 and 1998. Only skulls with complete closure were used in the analysis to ensure that differences between areas were not due to age-related factors. A total of 45 cranial, mandibular and dental measurements were taken using digital calipers to the nearest 0.01mm and total body weight with skin removed was measured to the nearest 0.5 kg. External body measurements were made with a measuring tape to the nearest mm and the weights of internal organs were taken to the nearest 0.1g.

520 $a Wolf carcasses were obtained from trappers across northwestern Ontario between 1995 and 1998. Only skulls with complete closure were used in the analysis to ensure that differences between areas were not due to age-related factors. A total of 45 cranial, mandibular and dental measurements were taken using digital calipers to the nearest 0.01mm and total body weight with skin removed was measured to the nearest 0.5 kg. External body measurements were made with a measuring tape to the nearest mm and the weights of internal organs were taken to the nearest 0.1g.
520 $a Adipose tissue measurements were made with calipers to the nearest mm and kidney fat was estimated as described by Harder and Kirkpatrick (1996). Wolf stomach and scat contents were washed and hairs were selected randomly and imprinted in clear nail polish for prey species identification (Adorjan and Kolenosky 1969). Scats of wolves and black bears were collected from transect lines throughout the moose and caribou ranges along roads and portage trails. Frequencies (%) were calculated within each prey category to allow comparisons among the three different range types: (1) no disturbance, (2) approximately 0 to 7 years post-harvest and (3) more than 7 years post-harvest.
