It is the purpose of this thesis to present information on the life of Gambusia patruelis. The study is the combination of data collected by a number of writers on this subject, as well as observations taken of this species from the Rio Grande and conservancy ditches surrounding Albuquerque.

A Study Of The Variations In The Growth Of Blue Grama Grass From Seed Produced In Various Sections Of The Great Plains Region, Andrew Riegel

Master's Theses or Doctor of Nursing Practice

During the past 7 years the Great Plains Region, with its "dust bowl", has been the scene of unparalleled activity in the fields of range management and erosion control. The people of this short grass area are extremely conscious of the need for a sound, practical program of conservation that will revegetate the wasted pasture and cultivated land, which will aid materially in preserving the eroding soil. Many problems have arisen as the program of conserving the soil and the vegetation has progressed.

Bulletin No. 290 - Phosphate In Utah, J. Stewart Williams

UAES Bulletins

Agitation for the development of the western phosphate field as part of the national program of conservation and economic rehabilitation has, in the last three years, focused public attention on the phosphate reserves of Idaho, Montana, Wyoming and Utah. In every conference or discussion on this subject, the minds of Utah's representatives have naturally turned to the question, "What is Utah's share in this great natural resource?" Obviously nature pays no heed to political boundaries, and neither does the prosperity of Utah's citizens depend solely upon that which is circumscribed within the state's boundaries. Nonetheless, it is necessary for Utahns …

Bulletin No. 289 - Business Analysis Of Farms In Utah County, Utah, Walter U. Fuhriman, W. Preston Thomas

UAES Bulletins

Project 179 of the Utah Agricultural Experiment Station - "A Study of the Agricultural Resources of Utah and their Utilization" - was set up in April 1936 as a state-wide project. The object of this project was to measure by areas the basic agricultural resources of the state and to translate the information collected into a program of more efficient use. The more specific objectives were: (1) classification of agricultural lands of Utah according to present and potential productivity and use; (2) determination of the net productive area of agricultural lands and water supply now available, or which may be …

Origin And Development Of Tissues In The Root Of Daucus Carota, L., M. Gerald Vodde

Bachelors’ Theses

When botanists of the seventeenth century began their anatomical investigations of plants, their attention was quite naturally centered on the parts of the plant which they most readily observed growing above the ground. The Englishman, Robert Hooke (1661), revolutionized the botanical sciences when he announced his discovery of the fact that plant tissues are composed of cavities which he called cells. Many workers enthusiastically took up the study of plant tissues and the individual cells of which these tissues are composed. Progress was rather slow, and it was not until approximately two hundred years later that the cell theory was …

The Pro-Embryo And The Embryo Of Chara, Mary William Saller

Bachelors’ Theses

From earliest times the Charales have drawn the attention of Botanists. Their structure and affinities have led to the most interesting and comprehensive research projects. However, the earliest results, in the light of present day research, differ particularly in one important respect; namely, the origin of the embryo.

A History Of The Changes In Population Of Certain Mammals In Western Kansas, Floyd L. Carter

Master's Theses or Doctor of Nursing Practice

This particular study has been restricted to certain mammals in western Kansas, including some on which there is little information, and others which observers would be most likely to notice in everyday life. For several years the writer has been vitally interested in the animal life in Kansas. Therefore, when the need for a study of western Kansas mammals was presented to him in the summer of 1936, the problem of this study was selected. It is hoped that this report will suggest to ecologists, historians, and others, further studies, including reasons for the changes here-in shown. What have been …

The Skull Of Squalus Acanthias, Allan J. Blake

Bachelors’ Theses

The spiny dogfishes (Squalus) inhabit the North and South temperate zones; they have no anal fins; the points of the small teeth are deflected laterally so ·chat the inner margin forms a cutting edge. Squalus Acanthius is very abundant in British waters and off the Atlantic coast of North America. This group has five gill openings and two dorsal fins each of which is typically preceded by a spine. It reaches a length of four feet, and is a great nuisance to fisherman, eating fish and getting caught in lines or in nets. They are all viviparous. Many …

Notes On The Origin And Development Of Zea Mays, Martin William Fleck

Biology ETDs

A combination of many and varied circumstances gives an unusual interest to the origin and natural relationships of Zea mays, although investigation of this sort does not always have an immediate utilitarian objective. But, this type of investigation must of necessity project itself into the remote, and sometimes obscure, past where attention becomes focused on many moot questions. Such intriguing problems as the relative antiquity of agriculture in the Old World, the length of time requisite for the development of maize as a human food stuff, and new ideas concerning techniques of aboriginal agriculture may perhaps be solved by information …

Plants And Animals Used As Sources Of Dye, Paint, And Skin Dressing In The Southwest, Mary Dennis

Biology ETDs

The area comprising the Southwest is somewhat disputed by different authors, but some idea of its extent and general features as well as some conception of the ethnology in relation to the tribes within the area is needed for an understanding of the scope of this investigation.

A Comparative Study Of The Skull And Long Bones Of The More Common Small Mammals Of Bernalillo County, New Mexico, Robert Theodore Fincke

Biology ETDs

The identification of animals or parts of animals without the aid of external characteristics is confusing problem in many fields of zoology. This is especially true in some studies as life histories and the food habits of predators. A problem of this type is even more confusing in New Mexico because relatively little work has been completed on the taxonomy and the distribution of the native fauna.

Bulletin No. 288 - Draingage And Irrigation, Soil, Economic, And Social Conditions, Delta Area, Utah Division 4: Social Conditions, Joseph A. Geddes, Carmen D. Frederickson, Eldred C. Bergeson

UAES Bulletins

This study is a part of a more comprehensive one which was organized in 1928 for the purpose of ascertaining what conditions existed in bonded irrigation and drainage districts which were unable to. liquidate obligations incurred.

The first such area to be studied was the Delta Area in Millard County. This area was selected for this study because of the pressing need for more detailed and wider information than was available to either the farmers or the bondholders and because available facts based on careful study might aid in achieving fairer settlements. These data might also assist other areas in …

The Food Of The Frog, Paul Schmitt

Bachelors’ Theses

All living organisms whether they be the smallest single cells or the largest mammals demand nourishment for their multifarious physiological processes. Popular and pseudoscientific thinkers and writers speak of nutrition in terms of food consumed, while true scientific investigators consider nutrition in relation to the actual assimilation of the components of food called proteins, fats, and carbohydrates.

The Histology Of The Grog's Tongue (Rana Pipiens), Michael William Mille

Bachelors’ Theses

The tongue is generally represented in all vertebrates although it varies widely in the extent to which it is developed. Among the fish it occurs in its most primitive condition. It is called a primary tongue and is merely a fleashy fold of dense connective tissue developed from the floor of the mouth between the hyoid and mandibular arches, the hyoid frequently extending into it and supporting it. It is incapable of motion except as moved by the supporting skeleton for it lacks intrinsic muscles. It is sensory, having both tactile and gustatory functions. It is often papillose, and in …

Bulletin No. 287 - Tests Of Corn Varieties And Hybrids In Utah, R. W. Woodward, D. C. Tingey, R. J. Evans

UAES Bulletins

The corn acreage in Utah is only about half that planted in barley and approximately one-fourth that sown to spring wheat. During the period 1910-30 this acreage was about equally divided into corn for grain, corn for silage, and corn fed to livestock in the field (table 1) . Since 1930 there has been a gradual increase in the acreage of corn grown for silage with the exception of the years 1936 and 1937.

Oil Provinces Of Colombia And Venezuela, William R. Ransone

Field and Laboratory

Colombia and Venezuela are by far the most important oil producing countries of South America. In 1938, Venezuela ranked third among the oil producing countries of the world, with a yield of 190,000,000 barrels. Only the United States (1,265,000,000 barrels), and Russia (210,000,000 barrels) outrank that country. Colombia, with 22,000,000 barrels was ninth among the petroleum producing countries of the world.

Drainage Controls In The Austin Chalk Cuesta Area Of Dallas, Texas, E. F. Blakemore Jr.

Field and Laboratory

The Austin chalk cuesta is a prominent topographic feature which trends northeast across central Texas from Austin through Waco and Dallas. The escarpment is formed through differential erosion of beds at the contact between the Austin chalk and Eagle Ford: shale, the overlying chalk forming the cuesta. The area described in this paper is situated 6 miles west of Dallas, south of the Trinity River Cross Valley.
