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
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 …

Population Regulation In Wolves, Jane M. Packard, L. David Mech
Population Regulation In Wolves, Jane M. Packard, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The possibility of social regulation of wolf populations has been discussed in the literature for several years. Some of the first ecological studies of wolves indicated that their populations did not increase as rapidly as was theoretically possible, and that they reached a saturation point apparently not set by food. Subsequent captive studies demonstrated the existence of social mechanisms possibly capable of regulating population growth. However, the importance of these factors in wild populations has not been established. This paper has four objectives: (1) to evaluate the existing concept of "intrinsic limitation," (2) to propose that wolf population dynamics may …

Wolf Howling And Its Role In Territory Maintenance, Fred H. Harrington, L. David Mech
Wolf Howling And Its Role In Territory Maintenance, Fred H. Harrington, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The wolf (Canis lupus) is a wide-ranging social carnivore with a complex spatial organization (MECH, 1972; 1973). The precise manner in which this organization is maintained is unknown, but territory advertisement using olfactory and acoustic modes seems to be involved.
The acoustic mode includes primarily howling. Within a wolf pack, howling may be useful to reassemble separated members (MECH, 1966; THEBERGE & FALLS, 1967), and may communicate information on individual identity, location, and other behavioral and environmental contingencies (THEBERGE & FALLS, 1967). Between packs, however, howling may serve to advertise territory, communicating the locations of packs and thus …

The United Nations Environment Programme, Norman Miller
Dartmouth Scholarship
It was once described as a part of the "quiet side" of the United Nations family, one of those organizations that did good works but rarely made headlines. Times have changed. Today the United Nations Environment Programme (UNEP), headquartered in Nairobi, Kenya, has come into prominence, not because of UN cliches about "spaceship earth," but because a great many ordinary people have come to realize they could be physically harmed by environmental hazards. The common man" in industrial states has begun to worry about the environment in respect to his health and the health of his children. He is asking …

Relating Wolf Scat Content To Prey Consumed, Theodore J. Floyd, L. David Mech, Peter A. Jordan
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
In 9 trials, captive wolves (Canis lupus) were fed prey varying in size from snowshoe (Lepus americanus) to adult deer (Odocoileus virginianus), and the resulting scats were counted. collectible scats were distinguished from liquid, noncollectible stools. In collectible scats, the small prey occurred in greater proportion relative to the prey's weight, and in lesser proportion to the prey's numbers, than did the remains of larger prey. A regression equation with an excellent the data (r2 = 0.97) was derived to estimate the weight of prey eaten per collectible scat for With this information …
Productivity, Mortality, And Population Trends Of Wolves In Northeastern Minnesota, L. David Mech
Productivity, Mortality, And Population Trends Of Wolves In Northeastern Minnesota, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Population parameters, mortality causes, and mechanisms of a population decline were studied in wolves (Canis lupus lycaon) from 1968 to 1976 in the Superior National Forest. The main method was aerial radio-tracking of 129 wolves and their packmates. Due to a decline in white-tailed deer (Odocoileus virginianus), the wolf population decreased during most of the study. Average annual productivity varied from 1.5 to 3.3 pups per litter, and annual mortality rates from 7 to 65 percent. Malnutrition and intraspecific strife accounted equally for 58 percent of the mortality; human causes accounted for the remainder. As wolf …

Habitat Use By Native Gambel' S And Scaled Quail And Released Masked Bobwhite Quail In Southern Arizona, John G. Goodwin Jr., C. Roger Hungerford
Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials
Populations of both Gambel's and scaled quail surveyed in southern Arizona declined by 60% from October 1975 to June 1976. Masked bobwhite population density increased during the study because of additional releases, but survival patterns are uncertain. Raptors were efficient quail predators.
Gambel's quail were associated with a dense overstory of mesquite, hackberry, wolfberry, and catclaw. Understory species varied in density and appeared less essential to good habitat. Scaled quail preferred open, grass-shrub habitat, with few of the plants over 6 feet tall. Masked bobwhite selected dense, grass-weed habitat, with pigweed a characteristic species.
Green vegetation and insects were seasonally …
Wolf-Pack Buffer Zones As Prey Reservoirs, L. David Mech
Wolf-Pack Buffer Zones As Prey Reservoirs, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Abstract. In a declining herd, surviving deer inhabited overlapping edges of wolf- pack territories. There, wolves hunted little until desperate, in order to avoid fatal encounters with neighbors. Such encounters reduce wolf numbers and predation pressure and apparently allow surviving deer along territory edges to repopulate the area through dispersal of their prime, less vulnerable offspring into territory cores.

Proceedings Of Perdix I: Hungarian Partridge Workshop, The Wildlife Society, Central Mountains And Plains Section, The Wildlife Society, North Dakota Chapter, North Dakota Game And Fish Department
Galliformes Specialist Group and Affiliated Societies: Conference Proceedings
Perdix I has succeeded in its major objective of bringing Hungarian partridge research and management people together in one place for introduction to one another and for a mutually beneficial exchange of information. A major communications bridge has been gapped by the informalization that occurs with the development of face-to-face relationships, a realization of how similar everyone's technical problems are, and an expression of concern regarding the need to develop work plans and guidelines to help direct future research and management by avoiding unnecessary duplication that often occurs with poor communications. As regards communications, it is refreshing to know that …

Research In National Parks, Robert J. Baker, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
This was our first involvement with research in the National Parks and we would like to make some observations concerning interactions among basic researchers, park personnel, and the philosophy on which our park systems are based. Our conclusions are not based only on our own experiences, but also on conversations with other basic researchers (especially those who contributed to this symposium) and with park personnel who have aided and worked with other researchers who were not employed by the National Park Service.
Pesticide Regulation And The Farm Worker, R. Craig Loveless
Pesticide Regulation And The Farm Worker, R. Craig Loveless
IUSTITIA
It has long been recognized that many pesticide products offer a potential hazard, which if unregulated, may result in injury or death. The development of highly toxic pesticides during the last decade has created a need for stricter regulation of pesticide use in the agricultural community. Specifically, the farm worker of today is in need of legislative protection from exposure to deadly chemical agents now being used to control pests and disease in the fields and orchards. Regulating the handling and use of these dangerous pesticides is but one way to protect the farmer, the farm worker, and the environment. …

Commoner's book provides an opportunity to review the problems of pollution and their causes in the social, political, and economic fabric of our society. This review also provides an opportunity to compare and contrast natural and social laws. From this examination of the problem of pollution and the interface between natural and social law emerge certain ideological concerns confronting Americans as a people.
