The Effects Of Recreation Specialization And Motivations On The Environmental Setting Preferences Of Backcountry Hikers, Randy J. Virden May 1986

The Effects Of Recreation Specialization And Motivations On The Environmental Setting Preferences Of Backcountry Hikers, Randy J. Virden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study explored how recreation specialization and different types of motivations were related to environmental settings preferred by backcountry hikers. A questionnaire was developed that measured the level of hiking specialization, desired psychological outcomes, and preferred environmental setting attributes. Questionnaires were mailed to 619 backcountry hikers from three Intermountain West hiking areas; a response rate of 68 percent was attained.

Results of the study revealed significant associations between the level of hiking specialization and the psychological states desired by backcountry hikers. In general, increased hiking specialization served to increase the importance of specific psychological outcomes such as autonomy, exercise, achievement …

Variations In Radial Maze Performance Under Different Levels Of Food And Water Deprivation, Robert H.I. Dale, William A. Roberts Mar 1986

Variations In Radial Maze Performance Under Different Levels Of Food And Water Deprivation, Robert H.I. Dale, William A. Roberts

Scholarship and Professional Work - LAS

Four groups of rats were tested on an eight-arm radial maze under a free-choice procedure. The subjects were maintained at either 80% or 100% of their preexperimental free-feeding weights through restricted access to either food or water. Water-deprived subjects received water in the maze; food-deprived subjects received food. Water-deprived subjects learned the task faster than food-deprived subjects. The four groups developed different response patterns. These were measured by the mean transition size, the average angular distance (in 45° units) between consecutively chosen arms. Rats foraging for food and water developed different search strategies, with water-deprived subjects exhibiting lower mean transition …


Variation In Piglet Weights: Relationship To Suckling Behavior, Parity Number And Farrowing Crate Design, David Fraser, B. K. Thompson Mar 1986

Variation In Piglet Weights: Relationship To Suckling Behavior, Parity Number And Farrowing Crate Design, David Fraser, B. K. Thompson

Ontogeny Collection

Suckling behavior and weight change of piglets were studied during the first 2 wk after birth. Thirty-six litters comprised a balanced comparison of parity number (first or second), litter size (8, 10 or 12), and two farrowing crate designs, one of which had a low horizontal bar that tended to impede the piglets' access to the udder. Piglets showed the expected preference for the anterior teats although the preference was more apparent in the second parity than in the first. Teat fidelity was most pronounced at the two ends of the udder; piglets occupying the middle positions did more fighting …

Spatial And Temporal Response Patterns On The Eight-Arm Radial Maze, Robert H.I. Dale Jan 1986

Spatial And Temporal Response Patterns On The Eight-Arm Radial Maze, Robert H.I. Dale

Scholarship and Professional Work - LAS

Six maze-experienced hooded rats were timed during five trials on which they collected water from all arms of an eight-arm radial maze, then made five more choices. All subjects frequently exhibited a “task-completion pause:” The subjects rarely spent more than 1 sec in the center of the maze between choices until they had entered all eight arms, then stopped in the center of the maze. In contrast, the time spent in each arm gradually increased until all of the water had been obtained, then decreased slightly. Four subjects began every trial by choosing eight consecutive adjacent arms. The task-completion pause …


The Case For Hunting, William L. Robinson Jan 1986

The Case For Hunting, William L. Robinson

Hunting Collection

My purpose at this symposium is to present the case for hunting. I am a wildlife ecologist by training and profession, and I am also a hunter. As a hunter, I am sensitive to criticisms of this pursuit, as any hunter should be. Some people question how, with knowledge of the nature and functioning of ecological systems, I can go out with a gun and kill grouse, ducks, and deer. I respond that, indeed, my understanding of ecology and the nature of man enhances my enjoyment of hunting.

The Case For Hunting On National Wildlife Refuges, Harvey K. Nelson

Hunting Collection

Public land management agencies are faced with greater challenges today than ever before in responding to the recreational needs of society. As Will Rogers so aptly stated, "Land, they make so little of it nowadays" (Steinhart 1986). The U.S. Fish and Wildlife Service (FWS) also must face these challenges in management of national wildlife refuges (NWRs). There is a growing demand by the American people to utilize and enjoy NWRs in a variety of ways. Managers are faced with the dilemma of determining how much and what kind of management and utilization of natural resources is appropriate without compromising the …


Effects Of Early Experience Upon Adaptiveness Of Horses, J. C. Heird, R. W. Bell, S. G. Brazier Jan 1986

Effects Of Early Experience Upon Adaptiveness Of Horses, J. C. Heird, R. W. Bell, S. G. Brazier

Equines Collection

Experimentation with laboratory animals, encompassing the range of usual species (mice, rats, cats, clogs, and primates), has conclusively demonstrated that handling by humans during early life facilitates subsequent development in terms of health and viability, reduced emotional reactivity, more adaptive responses to a variety of stressors (both biological and behavioral adaptations), and increased ability to adapt to changing circumstances as exemplified by increased ability to learn and solve problems (seeM. Bornstein 1985, for recent review).

Two studies (described below) (Heircl et a!. 1981; Whitaker 1982) conducted at Texas Tech University (TTU) have extended these findings regarding the beneficial effects of …


Assault On Eden: Destruction Of Latin America's Rain Forests, Douglas R. Shane Jan 1986

Assault On Eden: Destruction Of Latin America's Rain Forests, Douglas R. Shane

Ecology Collection

In the seemingly distant world of Latin America's rain forests, man's greed and desperation have resulted in a fire which threatens to obscure our ability to observe life's poetry: The continuing destruction of the earth's tropical rain forests is one of the most serious environmental problems confronting humanity today: Intact, these vital organisms offer an understanding of the planet's past and a key to our future; destroyed, they threaten catastrophe of global consequence.


The Case Against The Use Of Animals In Science, Donald J. Barnes Jan 1986

The Case Against The Use Of Animals In Science, Donald J. Barnes

Experimentation Collection

As a scientist long committed to the understanding, prediction, and control of biological, physiological, and behavioral events, I have no objection to the animal as a legitimate focus of science. As a parent, a son, a sibling, and the proud recipient of unconditional positive regard from a few special people, I am vitally interested in matters of health and in the most ethically efficient use of available resources. As a member of a species which has evolved sufficiently to allow the relatively broad perspective of a "web of life" and at least a rudimentary concept of altruism, I have laboriously …


The Case For The Use Of Animals In Science, James A. Will Jan 1986

The Case For The Use Of Animals In Science, James A. Will

Experimentation Collection

Animals are now used extensively in research and teaching, and the appropriateness of their use appears to be questioned. Some people believe that we are in a new era where the animal activists have become much more influential, and that the antagonism between the scientists and these groups is worse than it ever has been. This does not appear to be the case. The preeminence of various influences seems rather cyclic, even perhaps influenced by such things as economic conditions or wars. At present, the question is often asked, "Should we continue to use animals in science?" The real question …


The Cruel Deception, Robert Sharpe Jan 1986

The Cruel Deception, Robert Sharpe

Experimentation Collection

With new legislation to replace the Cruelty to Animals Act 1876 near at hand, the powerful vested interest groups whose profits and livelihood depend on laboratory animals are stepping up their campaigns to ensure the survival of vivisection. Have the benefits really been so great, and can vivisection achieve major advances in our present state of health?

History shows (McKeown 1979) that the real reasons for the dramatic increase in life expectancy since the middle of the last century are improvements in nutrition, living and working conditions, hygiene and sanitation, with medical measures only having a relatively marginal effect. The …


Socialized Vs. Unsocialized Wolves (Canis Lupus) In Experimental Research, Harry Frank, Linda M. Hasselbach, Dawn M. Littleton Jan 1986

Socialized Vs. Unsocialized Wolves (Canis Lupus) In Experimental Research, Harry Frank, Linda M. Hasselbach, Dawn M. Littleton

Experimentation Collection

In the experimental setting human contact is both more frequent and more intimate than in observational research, and the issue therefore assumes even greater importance. The present paper discusses two experimental studies of wolf information processing, one of which was conducted with unsocialized animals and one of which was conducted with socialized animals, and examines the both the management and methodological consequences of these approaches.


Wildlife And Nature Liberation, Michael W. Fox Jan 1986

Wildlife And Nature Liberation, Michael W. Fox

Conservation Collection

Humane ethics--animal welfare--and animal rights are not incompatible with ecologically sound wildlife stewardship. They are an integral part of it, from treating wildlife for necessary research purposes humanely, to finding humane ways to control the populations of species that are out of balance and thus threatening the viability of other species and the diversity and integrity of the ecosystem. That mistakes may be made in stewardshipmanagement policies is inevitable. It is, for instance, difficult to know if the sudden abundance of one or more species and the dwindling of others is part of the natural process of succession and should …


Wildlife Conservation And Animal Rights: Are They Compatible?, Michael Hutchins, Christen Wemmer Jan 1986

Wildlife Conservation And Animal Rights: Are They Compatible?, Michael Hutchins, Christen Wemmer

Conservation Collection

The purpose of this paper is to explore the philosophical tenets of the animal rights/humane ethic as they relate to the environmental ethic and, more specifically, as they relate to wildlife management and conservation. The two ethics will be compared in an effort to identify potential sources of conflict. Recent criticisms of the animal rights ethic, most notably by Fox (1978, 1979), Rodman (1977), Callicott (1980), Gunn (1980), and Hutchins et al. (1982) have identified several major discrepancies. The implications of these differences will be discussed.


Social Ecology And Behavior Of Coyotes, Marc Bekoff, Michael C. Wells Jan 1986

Social Ecology And Behavior Of Coyotes, Marc Bekoff, Michael C. Wells

Ethology Collection

Behavioral patterns are subject to natural selection and behavior like any other attributes of an animal, which contributes to individual survival. The chapter summarizes a long-term study of coyotes that was conducted in the Grand Teton National Park, in the northwest comer of Wyoming. There is remarkable agreement in the results stemming from a limited number of field projects concerned with the social behavior and behavioral ecology of coyotes, and some general principles concerning social ecology, scent marking, predatory behavior, time budgeting, and reproductive and care-giving patterns can be developed that are applicable not only to coyotes but to many …

The Case For The Use Of Animals In Medicine, Gary F. Merrill Jan 1986

The Case For The Use Of Animals In Medicine, Gary F. Merrill

Experimentation Collection

The use of animals in medical research and teaching, and the public concern this has generated is not a new issue (Visscher 1969). Ever since scientists began using animals to investigate the function of the body in health and disease, there have been those who opposed their work (Fishman and Richards 1982). Whether this controversy is cyclic is not known, but most concerned biomedical investigators agree that the opposition is here to stay. The author shares this opinion, and thus maintains that it is in the best interest of all parties to be properly educated on the issues. Only through …


Ethics, Welfare, And Laboratory Animal Management, David J. Allan, Judith K. Blackshaw Jan 1986

Ethics, Welfare, And Laboratory Animal Management, David J. Allan, Judith K. Blackshaw

Experimentation Collection

Animals have been used in medical research from as far back as 129-199 A.D. when Galen, a Greek medical scientist, used a pig for his experiments. In the sixteenth and seventeenth centuries, anatomical dissections were carried out on animals; Galvani used frogs in 1791 for his experiments and the Russian physiologist, Pavlov, carried out his famous dog experiments in the early 1900s. Since this time, large numbers of animals have been used in biomedical and other research. In 1963 the first edition of "The Guide for the Care and Use of Laboratory Animals" was published, and the United States Public …

Recovery Of Parasite Remains From Coprolites And Latrines: Aspects Of Paleoparasitological Technique, Karl J. Reinhard, Ulisses E. Confalonieri, Bernd Herrmann, Luiz F. Ferreira, Adauto J. G. De Araujo

Department of Anthropology: Faculty Publications

Standard techniques for the analysis of prehistoric soils have not been devised. It is unlikely that any single technique is applicable to all types of fecal remains. This is due to various environmental conditions which effect the preservation of helminth ova. In general, gravitational sedimentation is a useful technique for isolating helminth eggs and larvae from coprolites. Latrine soils pose greater problems for helminthological examination. Although various clinical techniques have been successfully utilized in soil study, it is important to remember that some latrine soils have not yielded helminth eggs to any clinical technique. Consequently the paleoparasitologist must be ready …


Interactions Between Response Stereotypy And Memory Strategies On The Eight-Arm Radial Maze, Robert H.I. Dale, Nancy K. Innis Jan 1986

Interactions Between Response Stereotypy And Memory Strategies On The Eight-Arm Radial Maze, Robert H.I. Dale, Nancy K. Innis

Scholarship and Professional Work - LAS

Three groups of water-deprived rats collected water from the ends of the 8 arms of an 8-arm radial maze. Sighted subjects, and subjects blinded either with or without pre-enucleation experience on the radial maze, all retrieved the water efficiently. Most of the subjects exhibited the same response stereotypy, regularly choosing 8 adjacent arms of the maze, then stopping in the center of the maze. The strategies underlying this performance were analyzed by interrupting trials and rotating the maze 180° after the subject had made 3 choices. Sighted subjects depended on extramaze stimuli, naive-blind subjects depended on intramaze stimuli and experienced-blind …
