The Settlement Of Teton Valley, Idaho-Wyoming, David Brooks Green Jan 1974

The Settlement Of Teton Valley, Idaho-Wyoming, David Brooks Green

Theses and Dissertations

Teton Valley, throughout many centuries, has attracted several occupance groups, each interacting with the environment in various ways for various reasons. Indian and explorer contact did little to alter the surroundings. More frequent contact came, however, as trappers and traders visited the valley to trap beaver and meet in rendezvous.

The end of intensified fur trapping slowed contact with the basin. Government personnel, a painter, a few squawmen and horse thieves were the only inhabitants because Indians, remoteness, and harsh climatic conditions kept others out until 1882 when permanent agricultural settlers entered the valley. Hundreds of people followed, many of …

Perception And Land Use: The Case Of The Mormon Culture Region, Lester D. Campbell Jan 1974

Perception And Land Use: The Case Of The Mormon Culture Region, Lester D. Campbell

Theses and Dissertations

Since the first man perceived and used his environment, there has existed a reciprocal man-land relationship. The physical environment provides opportunities for man's use and also sets limitations. Man's perception and use of his environment is greatly influenced by his culture, which consists of past experience, technology, attitudes, and needs. It is these factors that determine what a man will see as possibilities in land use, and how he will use his environment.

In the case of the relic Mormon Culture Region, Mormon religious beliefs highly influenced perception of the environment. Most visual geographical features of the landscape in the …

Scorpions Of The National Reactor Testing Station, Idaho, Dorald M. Allred Dec 1973

Scorpions Of The National Reactor Testing Station, Idaho, Dorald M. Allred

Great Basin Naturalist

During ecological studies in 1966 and 1967, 282 scorpions of Paruroctonus boreus (Girard) were collected in can pit-traps in 12 plant communities. The ideal habitat was in vegetated areas where the total ground cover was more than 85 percent, of which at least 60 percent was broad-leaf shrubs and 5 percent grasses. Populations of ants and spiders were highest where scorpions were most abundant. Scorpions were most active above ground during August, with about half as much activity during July. None were found prior to May or after September.

Light And Electron Microscopy Investigation Of Developing Wheat Caryopses Infected By Tilletia, Melvin Douglas Grove Aug 1973

Light And Electron Microscopy Investigation Of Developing Wheat Caryopses Infected By Tilletia, Melvin Douglas Grove

Theses and Dissertations

Caryopses of wheat were studied during infection by Tilletia caries and T. controversa. Initially the pathogens penetrated embryos of the host. After the embryo tissue was consumed by the fungi, endosperm tissue was penetrated and consumed. Initial penetration of endosperm tissue was in localized areas. During infection the fungus mycelium spread intercellularly, but occasionally was seen intracellularly. As the host tissue was consumed teliospores were formed. At maturity a host cell layer 4-6 cells thick remained which retained the mature teliospores. Histochemical studies indicated that carbohydrates and lipids of the host disappeared soon after invasion by the pathogens. Nuclei and …

Fate And Metabolism Of Bas 290-H In A Model Ecosystem, Kuo-Mei Chang

Theses and Dissertations

The use of chemicals to control economic pests has grown in this century both in the amount and the diversity of materials used (Headley and Lewis, 1967). About ten billion pounds of pesticides have been used in the United States since 1945. It is estimated that there are 340 million acres of cultivated lands in the Continental United States. Of this amount, approximately 119 million acres were sprayed with herbicides, 97 million acres were treated with insecticides and 25 million acres were treated with fungicides and other minor pesticides (Matsumura, 1972).

Interaction Between Triiodothyronine (T₃) And Thyroxine (T₄) In The Chick And The Rat, Kurtis George Cornish Aug 1973

Interaction Between Triiodothyronine (T₃) And Thyroxine (T₄) In The Chick And The Rat, Kurtis George Cornish

Theses and Dissertations

The secretion of two hormones with identical function by the thyroid gland has been questioned, What is the relationship between these two hormones? Why does the thyroid secrete two hormones when either one can provide for all the activity of the thyroid (Greer, 1972). Little work has been done on the relationship between the two hormones. There is some evidence showing that thyroxine (T4) is deiodinated to triiouothyronine (T3) at the tissue level in mammals. Chambers (1970) found that there was a negative interaction between T4 and T3 when pharmacologic doses were administered to the rat. The present study was …
