Mortality Of White-Tailed Deer In Northeastern Minnesota, Michael E. Nelson, L. David Mech
Mortality Of White-Tailed Deer In Northeastern Minnesota, Michael E. Nelson, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Abstract: Two hundred nine white-tailed deer (Odocoileus virginianus) were radiotracked in the central Superior National Forest, Minnesota, from 1973 through winter 1983-84; 85 deaths were recorded. Annual survival was 0.31 for fawns (<1.0 years old), 0.80 for yearling (1.0-2.0 years old) females, 0.41 for yearling males, 0.79 for adult (≥2.0 years old) females, and 0.47 for adult males. Monthly survival rates were high from May through December (0.94-1.00), except for yearling (0.60) and adult (0.69) bucks during the November hunting season. Most mortality occurred from January through April when gray wolf (Canis lupus) predation was an important mortality source for all cohorts. Yearlings males were most vulnerable to hunting and adult males to wolf predation.
Relationship Between Snow Depth And Gray Wolf Predation On White-Tailed Deer, Michael E. Nelson, L. David Mech
Relationship Between Snow Depth And Gray Wolf Predation On White-Tailed Deer, Michael E. Nelson, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Abstract: Survival of 203 yearling and adult white-tailed deer (Odocoileus virginianus) was monitored for 23,441 deer days from January through April 1975-85 in northeastern Minnesota. Gray wolf (Canis lupus)predation was the primary mortality cause, and from year to year during this period, the mean predation rate ranged from 0.00 to 0.29. The sum of weekly snow depths/month explained 51% of the variation in annual wolf predation rate, with the highest predation during the deepest snow.

Simulation Analyses Of Space Use: Home Range Estimates, Variability, And Sample Size, Marc Bekoff, L. David Mech
Simulation Analyses Of Space Use: Home Range Estimates, Variability, And Sample Size, Marc Bekoff, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Simulations of space use by animals were run to determine the relationship among home range area estimates, variability, and sample size (number of locations). As sample size increased, home range size increased asymptotically, whereas variability decreased among mean home range area estimates generated by multiple simulations for the same sample size. Our results suggest that field workers should ascertain between 100 and 200 locations in order to estimate reliably home range area. In some cases, this suggested guideline is higher than values found in the few published studies in which the relationship between home range area and number of locations …

An Analysis Of Howling Response Parameters Useful For Wolf Pack Censusing, Fred H. Harrington, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Gray wolves (Canis lupus) were studied from April 1972 through April 1974 in National Forest in northeastern Minnesota by radio-tracking and simulated howling. Based during 217 of 456 howling sessions, the following recommendations were derived for using howling as a census technique: (1) the best times of day are dusk and night; (2) July, August, and are the best months; (3) precipitation and winds greater than 12 km/hour should be avoided; (of 5 single howls should be used, alternating "flat" and "breaking" howls; (5) trials should 3 times at about 2-minute intervals with the first trial at lower …

Dynamics, Movements, And Feeding Ecology Of A Newly Protected Wolf Population In Northwestern Minnesota, Steven H. Fritts, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The gray wolf Canis lupus occupies only about 1 percent of its former range in the lower 48 states (Mech 1974a). Most of the range is in northern Minnesota, where the resident population is classified as "threatened" by the U.S. Department of the Interior. Wolves have been and will continue to be the subject of considerable controversy in Minnesota.
The first scientific study of wolves in Minnesota was conducted by Olson (1938a,b). That and all subsequent re- search was in the Superior National Forest (SNF) of northeastern Minnesota even though wolves inhabit approximately the northern third of the state. Consequently, …
Deer Social Organization And Wolf Predation In Northeastern Minnesota, Michael E. Nelson, L. David Mech
Deer Social Organization And Wolf Predation In Northeastern Minnesota, Michael E. Nelson, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The white-tailed deer Odocoileus virginianus has been subject to intensive research and management, yet we are just beginning to understand its social organization. Little is known about home range formation, migration, social bonds, and traditions in this deer, what functions they serve, and what selective forces have affected them.
Predation by wolves Canis lupus, in particular, has not been examined as a factor in deer evolution, yet the intimate interactions between deer and wolf through the millennia no doubt strongly influenced major morphological and behavioral adaptations in both species. It is a reasonable assumption that wolf predation has been …
