Rodenticide Selection And Bait Composition To Minimize Potential Primary Hazard To Nontarget Species When Baiting Field Rodents, Rex E. Marsh

Wildlife Damage Management Conference

A wide variety of methods is used to reduce potential hazards to non target species when baiting out-of-doors for rodents. The principles involved in making rodent baits highly selective hinge on the biology, particularly the feeding habits and food preferences of the target species. The differences or uniqueness of both the at-risk nontarget animals and the target animals should be assessed and then capitalized upon where possible in terms of susceptibility to toxicant, kind, size and shape of bait, etc. Generally only a few nontarget species are at risk in any particular situation, and the degree of this risk also …

Humans Versus Animals, William D. Fitzwater

Wildlife Damage Management Conference

In the beginning, humans and the so-called "lower animals" would meet cautiously and fleetingly, both intent on the basic goals of survival - food and water for the belly and shelter or other escape from more powerful enemies who regarded them as dinner entrees. This situation prevailed until puny man threw the first stone or swung a heavy club and realized that he could catch fleeter animals and kill larger ones than himself with his new tools. Thus instead of a grubby existence on plants, fruits, and insects, humans with their new toys eventually became efficient predators. Most of the …

Managing Coyote Damage Problems With Nonlethal Techniques: Recent Advances In Research, Samuel B. Linhart

Wildlife Damage Management Conference

In 1972 President Nixon issued Executive Order 11643 prohibiting further federal use of toxicants for controlling predators; EPA subsequently withdrew all chemical registrations for this purpose. These actions stimulated research efforts to develop alternate nonlethal means of reducing livestock losses to coyotes and other predators. Some of these studies, focused primarily on barrier fencing, guarding dogs, chemical repellents and aversive agents, "frightening" devices, and modification of leg-hold traps, have resulted in new ways to alleviate the problem.

Bird Repellent Seed Corn Treatment: Efficacy Evaluations And Current Registration Status, Jon F. Heisterberg

Wildlife Damage Management Conference

Bird damage to sprouting corn can be a serious problem for some farmers. Questionnaire surveys returned by 337 wildlife and agricultural specialists in 25 States indicated that losses of corn sprouts to birds in 1971 could amount to as much as $49 million (Stone and Mott 1973). Objective surveys in Kentucky and Tennessee in 1978 and 1979, respectively, set annual sprout losses to blackbirds (mainly common grackles [Quiscalus quiscula]) and crows (Corvus brachyrhynchos) at $1.8 million (Heisterberg, in press). Although losses in both states averaged < 1%, 32 (7%) of the 485 fields surveyed received > 1% losses accounting for 82% of the total damage.

The Effects Of Soil Texture And Related Soil Properties On The Distribution And Control Of Pine Voles (Microtus Pinetorum) In New York State Apple Orchards, John R. Whitney

Wildlife Damage Management Conference

The semifossorial microtine rodent Microtus pinetorum or the pine vole is well known as a destructive pest in fruit orchards (Hamilton 1935; Benton 1955; Burt 1957). The subterranean burrows of the pine vole often parallel the roots of apple trees, and damage occurs when the rodent gnaws the bark and cambial layers of large roots and severs smaller roots, occasionally even girdling the tree to more than a foot below the surface (Benton 1955; Pearson and Forshey 1978).

Wildlife Conflicts In An Urban Area: Occurrence Of Problems And Human Attitudes Toward Wildlife, Michael A. O'Donnell, Larry W. Vandruff

Wildlife Damage Management Conference

Today's world is undergoing increasing urbanization, and as most metropolitan expansions have resulted in urban sprawl, much original wildlife habitat has been heavily modified or eliminated. Populations of many wildlife species have decreased as a result of habitat changes, but at the same time, numbers of some native and many exotic species have increased in urban areas. As the process of urbanization continues and human's intensive use of land encroaches upon the use of land by wildlife, contact between people and wildlife will change in form and increase in residential areas.

Beaver Management In The Southeastern United States: A Review And Update, David K. Woodward

Wildlife Damage Management Conference

Beaver populations in primitive times have been estimated at 60 million animals distributed across the North American continent where adequate food and water existed (Seton 1900). History books document well the exploitation of this resource by trappers in the settling of the new world. The search for beaver was so efficient that by the beginning of the twentieth century only small numbers of animals remained in remote areas. During the early 1900's however, beaver populations began to increase for a variety of reasons. Foremost among these were trapping restrictions, but the absence of natural predators, reversion of abandoned farms to …

Fluoride Effects On The Growth And Morphology Of Two Thermophilic Cyanophytes Synechcoccus Lividus And Phormidium Laminosum, Ibrahim A. Arif

Biology

The effects of various concentrations of fluoride on growth of two thermophilic cyanophytes, Synechococcus lividus (unicellular) and Phormidium laminosum (filamentous) were studied. Growth of both algae was inhibited by fluoride in the concentrations tested. As the concentrations of fluoride increased, an extended adaptation lag phase was encountered. Synechcoccus lividus was more sensitive to fluoride than was Phormidium laminosum, being inhibited in total growth as well as growth rate. Fluoride effects on growth were compared to chloride and to chloride plus fluoride. The growth of S. lividus was stimulated by chloride alone and in combination with fluoride at all concentrations used; …

Using Videodisc Technology And The Index Of Nutritional Quality To Teach Dietary Guidance To Young Adults, Glenda Wigginton Edmunds

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A review of the literature indicated a need for nutrition education materials to be current with prevailing scientific knowledge, using advanced instructional technology. Individuals need help in applying nutrition principles to their dietary practices.

A nutrition education program utilizing the nutrient density concept and the dietary guidelines for use on videodisc with microcomputer interface was developed and evaluated. The evaluation of the program did not prove to be effective statistically but learners did show an interest in the program and had positive feedback in regard to the information presented and the technology used.

Accounting For Behavioral Contrast: Recent Interpretations, Ronald L. Snyder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Behavioral contrast has been interpreted as a function of either (1) the reduction of frequency of reinforcement in one component of a multiple schedule or (2) the suppression of responses in one component regardless of reinforcement frequency.

These explanations are discussed in terms of their adequacy in accounting for several recent experimental results. Two alternative explanations are considered.

First, contrast is interpreted as a function of the relative summation of excitatory and inhibitory effects of stimuli.

Second, contrast is discussed as a possible function of a switch from a response-reinforcer contingency to a stimulus-reinforcer contingency as seen in auto-pecking. Both …

The Effects Of Neutral And Sex-Specific Terminology On Sex Stereotyping, Natalie J. Malovich

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study was conducted to examine the effects of neutral and sex-specific terminology on sex stereotyping in regard to two primary questions: 1) whether or not the use of sex-neutral terminology alters subjects ' associations to particular words, and 2) whether, in the absence of gender identification, subjects make traditional sex-role assumptions about neutral terms. A third questions examined potential differences in male and female subjects' responses to neutral and sex-specific terminology.

Using a semantic differential technique, 40 male and 40 female volunteer subjects described a number of occupations and roles identified by sex-specific or sex-unspecified labels. Descriptions of those …

History Of The Forty-Second Parallel As A Political Boundary Between Utah And Idaho, Nancy Bergeson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The original purpose of this paper was to discover why Cache County, Utah at one time taxed towns now located in the State of Idaho. Later, it became apparent that a history of the forty-second parallel was necessary to fully understand the reasoning used by both the Federal and local governments in setting up the political boundaries of Utah and Cache County. Therefore, it was necessary to research the records of the Federal Government, Cache County Government, the LDS Journal History, and diaries of residents of Cache and Bear Lake Valleys, as well as detailed accounts of Spanish and Mexican …

Brown Trout Perception Of Ultraviolet Radiation And Possible Influence On Distribution, Terrence H. Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Brown trout (Salmo trutta), demonstrated an avoidance response to a range of intensities of artificial ultraviolet radiation in a laboratory setting. UV field measurements were made under a variety of riparian canopies in a mountain river system. UV values at various depth regimes were compared with laboratory response values. Results suggested that ultraviolet light could be a factor in the absence of brown trout in particular habitat types at various times during the daylight hours. Visible light intensity response values were also obtained under the same experimental and field conditions. These data suggested that visible light also could …

Mother-Infant, Father-Infant Relationships, Soheila Sobhani

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was designed to determine the contributions of mothers and fathers to infant social development. Nine 10-month-olds, 12 fourteen-month-olds, and 12 eighteen-month-olds were observed with their mothers and fathers in a laboratory situation. Parent-infant interactions were videotaped during three different episodes: Mother-infant dyad, father-infant dyad, and mother-father-infant triad. Findings revealed different interaction patterns as a result of the ages of infants and the interaction situation. Older infants and their parents engaged in more verbal behavior (responsive talk, social speech, and story reading) than younger infants and their parents. It was found that parents and infants interacted with each other …

Social Interaction: The Relationship Between Facial Attractiveness And Verbal Influence Style, Laurie Jean Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine if male and female communicators utilize different styles of persuasion with an attractive versus an unattractive female target. Forty undergraduate students were asked to persuade a female confederate in either an attractive condition or an unattractive condition to eat M&M's. Perceptions of attractiveness and personality assessments were checked by a post-experimental questionnaire. Influence attempts were rated and categorized by the use of the Social Interaction Scoring System. Individual responses were then factor analyzed to identify profiles of persuasive communication. These behavioral profiles were then statistically compared across experimental conditions by analyses of …

Stages Of Contemplative Mysticism: A Description And Taxonomy, Kenneth Burton Kaisch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to describe and classify the stages of contemplative mystical development in the major world religions. To accomplish this task, a sample of five major world religions was chosen from the total population. From each religion, a contemplative author who was regarded as an authority by the members of that religion was chosen. The major work of each author was described in order to make explicit his/her conceptualization of the stages of contemplative development. These conceptualizations were then compared together, resulting in two models of contemplative development. The first model was composed of those stages …

Establishment Of Tall Wheatgrass [Agropyron Elongatum (Host) Beav. 'Jose'] And Basin Wildrye (Elymus Cinereus Scribn. & Merr. 'Magnar') In Relation To Soil Water And Salinity, Bruce A. Roundy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The potential of basin wildrye (Elymus cinereus Scribn. & Merr. 'Magnar') and tall wheatgrass [Agropyron elongatum (Host) Beav. 'Jose '] to establish on saline, arid rangelands in the Great Basin in relation to soil water and salinity was compared in field and laboratory experiments. Tall wheatgrass had higher emergence and establishment on a nonsaline and a saline soil (electrical conductivity of the saturation extract of 7 dS·m^-1) over a range of spring precipitation as simulated by sprinkler irrigation. Basin wildrye will require supplemental irrigation to establish on soils of similar salinity. In the absence of precipitation, …

On The Effectiveness Of Agricultural Land-Use Controls, Eric Tarquin Marnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Land resources are a valuable resource in the economic system. There exists considerable controversy surrounding the allocation of land into the competing land uses. At the heart of this controversy are agricultural land resources. The purpose of this paper is to investigate, first theoretically and second empirically, the effectiveness of controls placed on land use to keep land in agricultural production.

A theoretical conclusion is reached as to whether the free market or 1 and-use controls allocate land resources more efficiently. An empirical model is formulated to explain changes in the quantity of agricultural land as a function of several …

The Economics Of Information And Spatial Price Behavior: An Empirical Assessment Of Producer's Cattle Prices In The Western Region Of The Usa: 1973-1981, Maria Lourdes Del Rosario Juan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is an empirical verification of the theories of the economics of information at the cattle producer's market in the U.S. Western Region. Weekly data on producer's price quotations were obtained from CATTLEFAX for 1973 through 1981. The three major objectives of the research are: first, to determine whether price dispersion exists in the cattle producer's market in the Western Region: second, if significant price dispersion are shown to exist, to determine the nature of the regional price distribution; and third, if price dispersion do exist, to determine the implications of the dispersion relative to competitive structure, efficient informational …

Only those documents authored by either the Geological Survey or the …

The Challenge Of Producing Native Plants For The Intermountain Area, U.S. Forest Service

All U.S. Government Documents (Utah Regional Depository)

Germination of wildland seeds is often dependent on proper seed collection and storage. A systematic approach to germination testing will often pinpoint the type of dormancy of seeds in wildland species and lead to germination enhancement.

Estimating The Rate And Amount Of Tree Loss From Mountain Pine Beetle Infestations, United States Department Of Agriculture, Forest Service

Forestry

Because of recurrent depredations by the mountain pine beetle in lodgepole pine, managers have less than a 50 percent chance of growing lodgepole pine to 16-inch diameters in most stands. This paper describes a Rate of Loss Model that estimates the amount of tree and volume loss per year and the longevity of the infestation, and shows how the model can be incorporated into forest planning. The model assumes optimum conditions for the life of an epidemic. However, actual field conditions can cause beetle populations to deviate from predictions causing a bit of overestimation, which is not considered serious in …

Comparison Of Model High-Latitude Electron Densities With Millstone Hill Observations, Jan Josef Sojka, Robert W. Schunk, J. V. Evans, J. M. Holt, R. H. Wand

All Physics Faculty Publications

Model predictions of the diurnal variations of plasma convection velocities and electron densities in the high-latitude ionosphere were compared with Millstone Hill incoherent scatter radar observations for an equinox day on which there was moderate magnetic activity. On the observation day, three major morphological features were evident at 500 km, including a dayside high density region, a nightside mid-latitude trough, and a region of slightly enhanced densities in the auroral zone. Although the dayside high density region was due to solar EUV radiation, it was not symmetrical about local noon (1000-1900 LT sector) owing to the effect of horizontal transport. …
