Amputation Of Vibrissae In Show Dogs, Thomas E. Mcgill

Veterinary Science and Medicine Collection

Dogs of many different breeds competing in the show-ring are routinely subjected to amputation of the vibrissae, organs that are commonly and incorrectly called "whiskers." This procedure is thought to give the animal's head a cleaner look, which in turn supposedly increases its chances of winning. There are several tricks involved in "whisker trimming" since the animals can retract each vibrissae at least one-quarter inch. Furthermore, they often object strenuously to the operation.

Stress: What Is It And How Can It Be Quantified?, T. H. Friend

Sentience Collection

An animal may be considered to be in a state of stress if abnormal behavior or extreme adjustments in its behavior or physiology are necessary in order to cope with adverse aspects of its environment. Methods used to determine if an animal is stressed can be either behavioral or physiological. Behavioral methods may be highly erroneous due to their subjective nature since alterations in behavior do not necessarily prove that an animal is stressed. There is no single measure of stress that can be used in all situations at this time. Every measure must be critically evaluated to ensure that …

The Social Behavior Of Brown Bears At Mcneil River, Alaska, Allan L. Egbert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The social behavior of brown bears (Ursus arctos) was studied during the summers of 1972 and 1973 as bears fished for salmon at McNeil River, Alaska. Study objectives were to determine behavioral characteristics of bears in relation to sex and age, changes in social behavior over a 40-day long fishing season, social and environmental parameters correlated with the occurrence of behavior, and to test the hypothesis that brown bears modify social behavior in a feeding aggregation to exploit a resource limited in time and space.

Over one-half of the agonistic interactions consisted of passive deferrals. Encounters that included …

Distribution And Behavior Study Of Diurnal Tree Squirrels In Portland, Oregon, With Emphasis On The Western Gray Squirrel (Sciurus Griseus Griseus Ord) And The Western Fox Squirrel (S. Niger Rufiventer E. Geoffroy St.-Hilaire), Ira Young Rice Iii

Dissertations and Theses

Populations of diurnal tree squirrels in the Portland area were located by mail surveys, personal interviews, and field inspections. Pine squirrels were found to reside in thickly wooded residential areas with dense understories and running water nearby. Western gray squirrels occupied habitats in relatively quiet residential neighborhoods, in areas well supplied with mast crops. Western fox squirrels were found to coexist with gray squirrels in their preferred habitat, and also to thrive in park settings with few mast trees and high activity and noise levels. In areas occupied by both fox and gray squirrels, dominant-subordinate relationships were noted. Each species …

A Behavioral Study Of A Small Group Of Pikas (Ochotona Princeps) On Mt. Hood, Oregon, Nancy A. Ewen Frazier

Dissertations and Theses

Observations or a small group of pikas, (Ochotona princeps) occupying a southwest facing roadfill on Mt. Hood, Oregon (1518 m) were made during the fall or 1976. Territorial sizes of 305.5 m² and 121 m² were determined based on territorial displays. These territories were compared with those observed in other studies. The mean distance to the nearest neighbor was 15.1 m. A pair relationship between two of the pikas and a dominance order are discussed. The seasonal progression of the haypiles and the reactions of the pikas to other animals are also noted.

Behavioral Temperature Regulation In The Turtle Pseudemys Scripta Elegans, Michael H. Johnston

Dissertations and Theses

A group of red-eared turtles (Pseudemys scripta elegans) was acclimated to 18-20˚C and artificial photo-period for 21 days. The animals were then individually placed in a thermal gradient and their selected temperatures were continuously recorded for 24 hours. A second group of turtles was acclimatized to 7.5-11.0˚C and natural photoperiods for 28 days, and subsequently tested in the same manner as the first group. Lastly, the turtles in the first group, after being acclimated to 3.0˚C and the previous artificial photoperiod for 14 days, were retested in the gradient.

The Intestinal Platyhelminths Of Southwestern And Central West Virginia Amphibia And Relationships Between The Degree Of Infestation And Habitat Of Amphibians And Sex Of Host, Stanley B. Mills

Theses, Dissertations and Capstones

In April and May, 1977, 397 (14 species) amphibians were collected from southwestern and central West Virginia and examined for parasites. Five species of trematodes and two species of cestodes were found from 93 hosts. The total of 397 amphibians was subdivided, for convenience, into six categories of amphibians; aquatic male and female, terrestro-aquatic male and female, and terrestrial male and female. Nine of 24 (37.5%). female aquatic amphibians was the highest incidence found, while terrestro-aquatic females contained the highest mean number (6.0) worms per incidence, and parasite loads of host. Hosts, each platyhelminth specimen are given.

Social Communication In Canids: Evidence For The Evolution Of A Stereotyped Mammalian Display, Marc Bekoff

Ethology Collection

The variability in the duration and form of the canid play bow was studied in infant coyotes, wolves, wolf-dog hybrids, beagles, and adult free-ranging dogs. Both duration and form showed marked stereotypy. It appears that the role of this context-specific social signal in the communication of play intention has been fostered by selection for "morphological" stereotypy.

Economics Of Farm Water Supplies, P P. Eckersley

Journal of the Department of Agriculture, Western Australia, Series 4

The economics of farm water supplies can be studied in two ways. One is to compare the costs of alternative ways of supplying a specified quantity of water to a farm. Another is to calcu;ate how mucha farmer can afford or will pay for a water supply.

I propose to look at these questions from the point of vieew of an eastern wheatbelt farmer, assuming that he must pay the full costs of any water supply provided for his property.

Radioprotection Of Oral Cavity Structures By S-2-(3-Aminopropylamino) Ethyl Phosphorothioate (Wr-2721), Ronald King

Masters Theses & Specialist Projects

Studies reporting a high concentration of WR-2721 in mouse salivary glands led to our studies of possible radioprotection of these glands by this drug from ionizing radiation. Oral effects of radiation in the presence of WR-2721 were studied in mice and dogs. Histological evaluation of mouse salivary glands irradiated with 1000 rads of ⁶⁰Co showed essentially no difference between control and experimental animals. Almost full regeneration of the serous salivary components occurred by 6 months in both groups and neither group had changes in the mucous glands. The use of higher doses of radiation in the mouse was prevented …

Heterospermic Insemination In Swine, Donald G. Levis

Electronic Theses and Dissertations

The studies report herein were conducted to evaluate (1) if there is a difference in pregnancy rate and litter size in swine between heterospermic and homospermic inseminations, (2) the effect of mixing various fresh cm n components involving spermatozoa in the sperm-rich fraction, seminal plasma from the centrifuged post-sperm fraction and Beltsville Ll extender on oxygen consumption, pH, motility and percent dead spermatozoa and (3) the effect of storage (54 hours) on oxygen consumption, pH, motility and percent dead spermatozoa in the various combinations. One Hampshire and one Yorkshire boar were used in the pregnancy rate and litter size study.

Chromosomal Banding Patterns Of The Holarctic Rodents, Clethrionomys Rutilus And Microtus Oeconomus, C. F. Nadler, V. R. Rausch, E. A. Lyapunova, N. N. Vorontsov, R. S. Hoffman

University of Nebraska State Museum: Mammalogy Papers

Biologists have long been aware of close similarities between the mammalian faunas of northern Eurasia and northern North America (Flerov 1967; Rausch 1953, 1963; Sushkin 1925; Tugarinov 1934). This similarity is particularly strong between species of tundra and taiga ecosystems (Hoffmann and Taber 1967; Hoffmann 1974). Among the species having Holarctic distributions, the boreal red-backed vole, Clethrionomys rutilus (Pallas), and the tundra vole, Microtus oeconomus (Pallas) (Rausch, op. cit.), of the subfamily Arvicolinae (= Microtinae) (Kretzoi 1962; Repenning 1968), have wide distributions in Eurasia where they inhabit, but are not restricted to, tundra (Ognev 1950; Corbet 1966). East of the …

Vocalizations Of Isolated Piglets. Ii. Some Environmental Factors, D. Fraser

Communication Skills Collection

The vocalizations of suckling piglets were studied during brief tests which involved social isolation, restriction of movement, and exposure to unfamiliar surroundings. Similar trends were shown in most cases by the three classes of call studied - closed mouth grunts, open mouth grunts, and squeals. The rate of calling was much lower when a piglet was in the home pen than when alone in an unfamiliar pen, and more calls were given in both situations when the animal’s movement was restricted by caging. The presence of the dam and four littermates in unfamiliar surroundings caused a large reduction in calling, …

Vocalizations Of Isolated Piglets. I. Sources Of Variation And Relationships Among Measures, D. Fraser

Communication Skills Collection

The vocalizations and activity of suckling piglets aged 4 to 25 days were studied during 5-min periods of social isolation in an unfamiliar enclosure. The animals became very active and vocalized repeatedly during the test, but the reaction was attenuated among older litters. Calls were predominantly closed mouth grunts at low rates of calling, and mainly squeals and open mouth grunts at high overall rates. Squealing correlated with open mouth grunting and with the activity measure both within and between litters. Even so, the measures appeared to be affected independently by the piglets’ behaviour in the home pen just before …

An Analysis Of Sound Communication In The Water Vole, Microtus Richardsoni (Rodentia: Microtinae), Dane R. Tang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adult members of the species Microtus richardsoni were used to study the importance of acoustic communication in these voles. Tests were run with single individuals and nonbreeding pairs of voles to obtain recordings and sonagraphs of sounds emitted during exploration of a new cage, agonistic encounters, encounters with a potential predator and in response to miscellaneous aversive stimuli. Of the four groups of tests conducted, sounds were used by M. richardsoni during the last three. The results of this study showed that the water vole emitted ten different call types or sounds. These sounds were separated by similarity into Group …

Special Report On Controlling America's Pet Population

Special Reports

HSUS estimates that public and private animal control programs cost the nation as much as $500 million a year. Much of this expense is required for the feeding and care of unwanted animals during the 5 to 10 days they are held for adoption, killing the 80% that are not adopted or redeemed, and disposing of the carcasses. The result is both an unconscionable waste of life and a needless drain on public and private money.

A large part of the blame for people undertaking pet ownership without having made a total commitment to the animal lies with the pet …
