A Study Of Fleas Of Rodents In The Albuquerque, New Mexico, Area, Lelia Ann Williams

Biology ETDs

In spite of the fact that Pasturella pestis, the the etiological organism of plague, has been reported from fleas and rodents in eleven counties of New Mexico, our knowledge of the fleas of the State has remained very incomplete and extremely meager. Recognizing the marked deficiency regarding our information of the Siphonaptera of New Mexico, I began in the spring of 1948 an investigation that has resulted in adding considerable information to our knowledge of the flea population of our State.

The present study includes a report of 36 species and subspecies of fleas recovered from several nests and by …

A Bioecological Study Of Pinyon Pine-Juniper Association At Juan Tabo In The Sandia Mountains Of New Mexico, Robert Hallett Parker

Biology ETDs

A survey of literature shows that no community or bioecological study has ever been made of the pinyon pine-juniper association as it occurs in the Upper Sonoran Life Zone in New Mexico and southern Colorado. This deficiency of knowledge relative to the pinyon pine-juniper community is in direct contrast to several studies that have been made of the same community in Arizona and Utah by the presence of dominant trees of entirely different species. Relative to the association in New Mexico, one of the dominant tress, the pinyon pine (Pinus edulis Engelm), has been investigated, but no bioecological and …

The Determination Of Choline Esterase Activity In Whole Brains Of Developing Rats, Charles Joseph Metzler

Biology ETDs

It is the purpose of this paper to report the results of quantitative investigations of the choline esterase activity in the rat in various states of its life cycle. Some work has been done on the acetylcholine content (Welsh and Hyde, 1944) in rats of various ages, but there is no reference in the literature to complete the quantitative determinations of the choline esterase activity in the whole brain of the rat throughout its life cycle.

A New Elasmosaur From The Eagle Ford Shale Of Texas: Systematic Description, S. P. Welles

Fondren Science Series

The elasmosaurs were marine reptiles, plesiosaurs with extremely long necks and proportionately very small heads. The larger individuals of the Upper Cretaceous attained a length of forty feet, with necks over twenty feet long. Their limbs were so highly modified into paddles that progress on land must have been extremely difficult, if not impossible. Their long sharp teeth indicate a fish-eating habit, and this has been confirmed by the fossilized stomach contents. The fish were evidently gulped down whole and ground up in a gizzard-like organ which contained stomach stones.

A Preliminary Study Of The Siphonapterous Ectoparasites Found On The Mammals Of The Families Cricetidae And Muridae In Utah County, Vernon J. Tipton

Theses and Dissertations

The purpose of this study was to determine the species of fleas infesting the mammals of the families Cricetidae and Muridae in Utah County. This was accomplished by establishing twelve collecting stations throughout the county from which 198 mammals were collected. From these hosts, 392 fleas were collected representing three families, nineteen genera , and twenty-four species. Four species are new to the State of Utah and twenty-two species are recorded from Utah County for the first time.

The Diet And Daily Forage Consumption Of An Experimental Herd Of Sheep On Utah's Winter Range, Lee A. Sharp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The forage produced on Utah’s winter range is generally deficient in some nutrients that are required for the phase of sheep production that takes place on these ranges. This forage need only supply little more than maintenance ration, but because of low forage production on these areas and generally low quality forage, these requirements often are not met.

Emergence And Survival Of Four Introduced Wheatgrasses As Influenced By Rate And Season Of Planting On Abandoned Farm Lands Of Utah, Donald N. Hyder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A great deal has been accomplished in developing methods of restoring abused lands through seeding, yet there is much to be desired in refinement of techniques and in substantiation of previous experimental results. Controversial opinions as to the best season of planting indicate that additional trials are needed. New species need to be introduced, developed, and proved. Methods are needed which lead to more efficient utilization of those factors limiting the degree of success in establishment. Since moisture is the most predominant limiting factor throughout the arid and semi-arid range land, special attention is given to more efficient utilization of …

An Evaluation Of Trout Stocking In The Logan River Drainage, Nels Andrew Thoreson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the more important forms of recreation in Utah is fishing. Each year since the end of World War II more than 100,000 resident and 4,000 non-resident fishermen have taken to the streams and lakes of this state. They spend approximately $2,200,000 each year in the quest of fish, mostly trout. In 1916, 25,473 licenses were sold, in 1937 the number of licenses had risen to 41,200, in 1945 the sales amounted to 104,000 and in 1947 had increased to nearly 131,000. Because of the increased number of fishermen each year, the desirability of greater numbers of legal-sized fish …

Some Factors Associated With The Economic Feasibility Of Reseeding Privately-Owned Cattle Ranges In Utah, James R. Gray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The forage depletion of western ranges which has occurred during the past century is partly the result of the belief by ranchers that the forage loss was temporary and not serious. Should more forage of a high quality be desired they thought it could be produced by reseeding the ranges. The native western forages, never abundant or luxurious by eastern concepts, nevertheless were of generally high qualities. Limited by low and erratically distributed precipitation, the sparse native forages have in many areas given way to low quality plants. These plants of low quality do not have to withstand the adverse …

The Introduced Fishes, Game Birds, And Game And Fur-Bearing Mammals Of Utah, Boris Hewitt Popov

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For a number of years wildlife workers have realized the importance of the past histories of introduced species. Emphasis in recent years has been directed toward introductions because of the tremendous hunting and fishing pressures. Yearly increases in numbers of hunters and fishermen have been noted in Utah for the past forty years. It is hoped that this compilation of the histories of the introduced game and fish species of Utah will be of value to sportsmen and wildlife managers alike in planning future introductions.

The material included in this paper was obtained from United States Government reports, Utah Territorial …

A Study Of Semisterility And Its Lineage Relationships In Translocation Stocks Of Barley, Horace Marr Waddoups

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley (Hordrium sp.) is the most important spring sown cereal crop in Utah, both in acreage and in yield of total digestible nutrients per unit area. It also rates high as a feed crop in the United States. For this reason it is important that varieties are available which are high in yield, high in quality, and disease resistant, along with other desirable characteristics. In order to work toward this end most efficiently, it is first necessary that the genetics of the barley plant be worked out.

Seed And Forage Production In Four Clonal Lines Of Alfalfa As Influenced By Lygus Infestation, John Keith Noyes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

No other forage crop cultivated in the United States can be used in as many ways as alfalfa. The variety of its uses make it a most useful forage crop.

The distribution of alfalfa is world wide and it plays a leading role in the production of livestock and their products. For general feeding of farm animals, alfalfa is unsurpassed. Used for pasture, it has a high capacity, which leads to large gains in grasing animals. If properly rotated and cared for, it adds nitrogen to the soil in a form that is available to plants and thereby increases crop …

Inheritance Studies In Stem Rust Of Wheat, Sayed Bad Shah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wheat is an important food crop of the world, especially in Soviet Russia, U.S.A., China, India and Pakistan. Over one billion bushels of wheat are produced annually in U.S.A. The total area under wheat production in Pakistan during 1947-48 was 10 million acres with an average yield of 12 bushels per acre.

The stem rust disease has been known for along time to be destructive to grain crops, even centuries before the Christian era. Rust is of major importance in both the U.S. and Pakistan. Jethro Tull recorded rust in England in 1725. In 1916, rust was serious over the …

The Effect Of Time, Quantity, And Kind Of Irrigation On The Yield Of Sugar Beets, Delos Boyd Archibald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Investigations on factors affecting yield of sugar beets during the past two years at Newton and Garland, Utah, have shown two outstanding facts about irrigating sugar beets. First, the amount of water applied may not be as important as the time at which they receive it. Second, sugar beets should not be made to suffer for water in the early part of their growing season.

These observations suggest the need for further studies on method, time and quantity of irrigation. Further information on the most economical use of irrigation water for sugar beets would be of great value to the …
