The Environmental Crisis: The Effects Of Ecology Courses On High School Students, Carol C. Fletcher

Dissertations and Theses

It is a basic premise of this thesis that an environmental crisis exists in the world today and has been worsening at least since World War II. The crisis is evident in the population explosion, the deteriorating air and water quality, and the depletion of our natural resources. With the feeling that all persons must become aware, concerned, and involved with the environmental crisis if the trend is to be reversed, this study is concerned with one segment of the population – high school students.

Sociologists, and especially human ecologists, have not been concerned professionally with the environmental crisis, but …

The Allelopathic Influences Of Sassafras Albidum In Old Field Succession In Tennessee, Robert Edward Gant

Masters Theses

The purpose of this investigation was to study the mechanism that allows Sassafras albidum to maintain itself in relatively pure stands through many successional stages. Sassafras albidum is a common woody member of the old field community in Tennessee, invading in the early seral stages and surviving into the mature forest. Compounds known to be inhibitory to plant growth have been isolated from sassafras by other investigators. The presence of these terpenoid compounds in various organs of this plant suggests the existence of a possible allelopathic interference mechanism.

A survey of the internal and external herbaceous ground cover revealed the …

An Investigation Of The Behavior Of Citellus Townsendii Townsendii (Bachman) In Central Washington, Mark Roy Fuller

All Master's Theses

This study of the behavior of Citellus townsendii townsendii was based on field observations of animals at their northern most distribution. The squirrels' seasonal activity and behavioral repertoire, when considered with environmental parameters, suggest important adaptations for survival. The animals were in torpor from about July to February. Activity generally occurred during the midmorning hours, allowing them to avoid temperature extremes. Quantitative analysis of behavioral observations indicated that most activities occurred in a non-random order.

Some Interactions In The Evolution Of Man And Tools, Gary W. Weston

All Master's Theses

This paper looks at some of the interactions between the development of tools and the evolution of man and his ancestors. It begins with a brief history of life up to the primates as a foundation. Next the use of tools by other animals is examined followed by the coverage of the period of time from Australopithecus to Modern Man showing the interweaving of physical and mental evolution of man and the development and refinement in his physical tools. Lastly, a look at possible future interactions in the physical and mental evolutionary developments in man as influenced by his tools …

Notes On The Biology Of The Central American Squirrel, Sciurus Richmondi, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Additional specimens of Sciurus richmondi are reported, along with comments on variation, distribution, reproduction and molt in this little known squirrel. As presently understood, S. richmondi occurs only in the Caribbean rain forests of Nicaragua. Significant secondary sexual variation in adults was found only in zygomatic breadth, in which females are the larger. Available evidence reveals that the breeding season extends at least from February to September, and suggests two seasonal molts annually.

Evaporative Water Loss In Two Northwest Snakes: Pituophis Catenifer And Crotalus Viridis, Donald R. Woolery

All Master's Theses

A study by Gans, Krakauer and Paganelli (1968) dealt with twenty-six species of snakes representing five families. They found that the "rate of water loss was proportional to surface area" and that water loss correlates with the aridity of the selected habitat. No comparative information resulting from the direct separation of the pulmonary and cutaneous avenues of water loss is currently available. Also, no direct comparisons of this separation in sympatric species are available. These comparisons are the basis for this study.

Ecological Life History Of Rudbeckia Occidentalis Nutt, Juan Arturo Florez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phenological studies of coneflower on aspen range in Northern Utah showed that resumption of growth of mature plants begins at the time of snow melt and the initial or rosette stage is completed between mid-May and mid- June. The rate of growth in this stage is controlled by temperature, being greater at higher mean temperatures. The bolting stage is completed about 1 week after the initiation of stem elongation and the process of capitulum development is begun. Flowering is initiated between late July and mid- August. Cross-pollination is necessary for seed set which is completed by the end of August. …

Sub-Aversive Response Contingent Foot Shock As A Positive Reinforcer, Robert Lea Fulwiler

All Master's Theses

Forty-eight rats were divided into 8 groups; four were maintained under normal conditions and the other four under sensory deprivation and tested at o, 3, 6, and 9 days after condition institution. The response was placing the head through a hole in the operant chamber and the stimulus (0, 1.2, 4, or 12 Vac) was contingent upon the response. Analysis ot variance disclosed significant differences (p<.01) between the deprived and the non-deprived groups at days 6 and 9; and a significant interaction between deprivation condition and time of test. No differences were shown between the stimulus intensities indicating that the stimulus did not have a reinforcing effect.

Preliminary Estimates Of Bark Percentages And Chemical Elements In Complete Trees Of Eight Species In Maine, Harold E. Young

Aspen Bibliography

Five tables were prepared to show the relative amount of bark on each of the tree components, the concentration and range of 12 chemical elements in the bark of each tree component, the proportion of each of the chemical elements in the bark of that element in the complete tree, and the proportion of each element in the bark as compared to the wood and bark of the merchantable bole. There is an overall 4:6:1 wood to bark ratio, but due to the higher concentration of the elements in the bark, the proportion of the elements in the bark is …

Spawning And Early Life History Of Largemouth Bass (Micropterus Salmoides) In Wahweap Bay, Lake Powell, Kent D. Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spawning time and habitat of largemouth bass, survival of embryos, and growth and food habits of fingerlings were studied in 1968 and 1969 at Wahweap Bay, Lake Powell. Spawning began in mid- to late-April, when mean daily water temperature at nesting depths was 14.4-15.0 Centigrade (58-59 Fahreheit), and continued until mid-June. Most spawning took place on the northeast shore of the bay. Sandstone rubble was the most commonly used bottom type for nesting, either at the base of ledges or around large sandstone boulders. Mean nest depth increased from 1.63 meter to 4.54 meters (5.36 feet to 14.90 feet) in …

Spring And Summer Habitat Preferences Of Blue Grouse On The Bear River Range, Utah, Robert M. Maestro

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of the spring and summer habitat preferences of blue grouse was conducted on the Bear River Range in northern Utah. The main objective was to determine the important factors associated with habitat selection by blue grouse during the breeding season.

One hundred and two sampling areas, delimited by similarities in vegetation and topography, were thoroughly searched with a dog for blue grouse. Fifty-four biological and physical variables were measured for each sampling area.

Chi-square tests performed on all variables showed 11 of the 54 variables to be significant at an alpha of 0.20. These 11 variables (listed below) …

Ecology Of Badgers In Curlew Valley, Utah And Idaho With Emphasis On Movement And Activity Patterns, Frederick G. Lindzey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Between March, 1969 and July, 1970, 16 badgers (Taxidea taxus) were caught and fitted with radio transmitters in the southern part of Curlew Valley. The animals were followed telemetrically; seven animals contributed sufficient data from which home-range, movement and activity patterns could be discerned. The aver age annual home-range size of five females was 664 acres (± s.d. 99 .5 acres). Female home-range sizes were approximately the same within crested wheat-grass (Agropyron aristatum) and sagebrush (Artemisia tridentata) vegetation types, with greater distances traveled each night by females in the crested wheat-grass. Both home-range size and total movement were less …

The Nitrogen Budget Of Two Salt Desert Shrub Plant Communities Of Western Utah, Richard S. Bjerregaard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The nitrogen budgets of Eurotia lanata (Pursh.) Moq. and Atriplex confertifolia (Torr. and Frem.) S. Wats salt desert shrub plant communities were investigated. In each, a complete biomass and organic nitrogen inventory was made. In addition, investigations of the nitrogen fixation potential of soil surface microflora and inorganic soil nitrogen relationships were carried out.

Greater total biomass and organic nitrogen was found in the above-ground portions, annual shoot productivity, and litter of the Atriplex community. However, the Atriplex community was exceeded by the Eurotia community in root biomass. Roots accounted for 74 and 87 percent of the plant biomass and …
