White-Tailed Deer (Odocoileus Virginianus) Fawn Risk From Gray Wolf (Canis Lupus) Predation During Summer, L. David Mech, Aaron Morris, Shannon M. Barber-Meyer
White-Tailed Deer (Odocoileus Virginianus) Fawn Risk From Gray Wolf (Canis Lupus) Predation During Summer, L. David Mech, Aaron Morris, Shannon M. Barber-Meyer
USGS Northern Prairie Wildlife Research Center
Little is known about how often various prey animals are at risk of predation by Gray Wolves (Canis lupus). We used a system to monitor the presence during the day of two radio-collared Gray Wolves within 2 km of a radio-collared White-tailed Deer (Odocoileus virginianus) with a fawn or fawns in August 2013 in the Superior National Forest of northeastern Minnesota. We concluded that the fawn or fawns were at risk of predation by at least one wolf at least daily.
Wolves, Canis Lupus, Carry And Cache The Collars Of Radio-Collared White-Tailed Deer, Odocoileus Virginianus, They Killed, Michael E. Nelson, L. David Mech

Wolves (Canis lupus) in northeastern Minnesota cached six radio-collars (four in winter, two in spring-summer) of 202 radio-collared White-tailed Deer (Odocoileus virginianus) they killed or consumed from 1975 to 2010. A Wolf bedded on top of one collar cached in snow. We found one collar each at a Wolf den and Wolf rendezvous site, 2.5 km and 0.5 km respectively, from each deer’s previous locations.
Wolf, Canis Lupus, Visits To White-Tailed Deer, Odocoileus Virginianus, Summer Ranges: Optimal Foraging?, Dominic J. Demma, L. David Mech
Wolf, Canis Lupus, Visits To White-Tailed Deer, Odocoileus Virginianus, Summer Ranges: Optimal Foraging?, Dominic J. Demma, L. David Mech
USGS Northern Prairie Wildlife Research Center
We tested whether Wolf (Canis lupus) visits to individual female White-tailed Deer (Odocoileus virginianus) summer ranges during 2003 and 2004 in northeastern Minnesota were in accord with optimal-foraging theory. Using GPS collars with 10- to 30-minute location attempts on four Wolves and five female deer, plus eleven VHF-collared female deer in the Wolves’ territory, provided new insights into the frequency of Wolf visits to summer ranges of female deer. Wolves made a mean 0.055 visits/day to summer ranges of deer three years and older, significantly more than their 0.032 mean visits/day to ranges of two-year-old deer, …
Precision Of Descriptors For Percent Marrow Fat Content For Whitetailed Deer, Odocoileus Viriginianus, L. David Mech
Precision Of Descriptors For Percent Marrow Fat Content For Whitetailed Deer, Odocoileus Viriginianus, L. David Mech
USGS Northern Prairie Wildlife Research Center
Based on 168 records of both verbal descriptors of White-tailed Deer (Odocoileus virginianus) femur-marrow fat and percentage of fat measured later, “gelatinous” served well to distinguish fat < 46% from higher percentages. “Waxy” distinguished fat > 56%.
Do Wolves Affect White-Tailed Buck Harvest In Northeastern Minnesota?, L. David Mech, Michael E. Nelson
Do Wolves Affect White-Tailed Buck Harvest In Northeastern Minnesota?, L. David Mech, Michael E. Nelson
USGS Northern Prairie Wildlife Research Center
We used simple linear regression to analyze 8-23 years of data on a wolf (Canis lupus) population and human harvest of white-tailed deer (Odocoileus virginianus) bucks in northeastern Minnesota to determine any effects of wolves on buck harvesting. Over the long term, wolves accounted for at least 14-22% inter-year variation in buck harvest in the region, but an unknown amount of variation in hunter effort have obscured any more precise estimate. For part of the area with poorest habitat, we found strong relationships (r2 = 0.66-0.84) between annual wolf numbers and buck harvests from 1988 …
Proximity Of White-Tailed Deer, Odocoileus Virginianus, Ranges To Wolf, Canis Lupus, Pack Homesites, Michael E. Nelson, L. David Mech
Proximity Of White-Tailed Deer, Odocoileus Virginianus, Ranges To Wolf, Canis Lupus, Pack Homesites, Michael E. Nelson, L. David Mech
USGS Northern Prairie Wildlife Research Center
Seven adult female White-tailed Deer (Odocoileus virginianus) in northeastern Minnesota lived within 1.8 km of Wolf pack (Canis lupus) homesites without vacating their home ranges. Six of these deer and at least three of their fawns survived through the Wolf homesite period.
