Life History Of The Utah Sculpin Cottus Bairdi Semiscaber (Cope) In Logan River, Utah, William M. Zarbook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of the Utah sculpin in Logan River was based on 801 specimens collected during 1949 to March 1951. Numbers of fish examined for various catagories of the study wares length-frequency, 495; aging by vertebrae, 407; length-weight relationship, 601; and food habits, 275.

Fish were collected by use of an electric shocking machine generating 600 watts and 220 volts. Numbers of fish occurred as high as 150 per tenth mile of stream. Preferred habitats occurred in areas of coarse gravel and small rocks.

Vertebrae dissected from the fish were used in age determination. Length-frequency proved to be a general …

The Desert Shall Blossom As The Rose, D. Wynne Thorne

Faculty Honor Lectures

IRRIGATION AGRICULTURE has not received attention commensurate with its significance in either ancient or modem times. Although most ancient civilizations depended on irrigation for their very existence, one can consult volume after volume of history only to find irrigation scarcely mentioned. To the agricultural specialist the great challenge and the strength and weakness of irrigation agriculture is not in constructing Boulder Dams nor in planning winding canals and syphons to carry water from the Columbia River to California. The critical point is on the farms where water is applied to the soil and crops are harvested. There the real battles …

Notes On The Agave Feeders Of The Genus Megathymus (Lepidopter Rhopalocera, Megathymidae), H. A. Freeman

Field and Laboratory

Life histories of most of the species of Megathymus long have been associated with the genus Yucca; but John A. Comstock & Charles M. Dammers found that Megathymus stephensi Skinner has as its food plant a certain species of the genus Agave (Bull. So. Calif. Acad. Sci., XXXIII, 1934). Later, it was found that another species of Megathymus feeds in the larval stage upon agave. Although I have been unable to find any published note on the feeding of Megathymus mariae B.&B. upon Agave lecheguilla Torrey, lepidopterists have known this fact for a considerable time. There remain four species of …

Bulletin No. 350 - Cemeteries Of Box Elder And Summit Counties, Joseph A. Geddes, Carmen Fredrickson

UAES Bulletins

One of man's greatest challenges is to build institutions that adequately meet basic needs. A cemetery is a social institution invented to take care of needs related to the dead.

Times and conditions change. A design which seemed adequate when initiated may soon become archaic and out-moded if it is not modified in the light of new discoveries.

This study raises many issues about cemeteries. As one reads the bulletin many questions concerning the nature and function of other institutions arise. What is their condition in contrast with the cemeteries?

This publication, the first in an institution series planned by …

The Affect Of Indole-3-Acetic Acid On The Fission Rate Of Paramecium Caudatum, Margherita L. Baker

Student Scholarship

This research report, authored by Margherita L. Baker in 1951, investigates the physiological effects of the plant growth hormone indole-3-acetic acid, also known as heteroauxin, on the fission rate of the protozoan Paramecium caudatum. The study is grounded in the hypothesis that if plant hormones can influence animal growth, it suggests a fundamental similarity in the growth mechanisms between the two kingdoms. The experimental procedure was divided into two distinct series to observe how varying environmental conditions and food availability influenced the hormonal impact. 

In the first series, paramecia were maintained in a nutrient-rich beef extract medium with an abundant …

The Sedimentation Rate Of Potato Yellow-Dwarf Virus, M. K. Brakke, L. M. Black, Ralph W. G. Wyckoff

Department of Plant Pathology: Faculty Publications

BLACK et al. (1948) have published electron micrographs of bodies believed to represent the New York variety of potato yellow-dwarf virus (Aureogenus vastans (H) Black) (Holmes 1948). The photographs showed bodies in several different extracts of infected plants of Nicotiana rustica L., but not in corresponding preparations from healthy plants. Similar bodies were found in concentrates from plants infected with the New Jersey variety of the virus (var. agalliae Black). These bodies were larger than, and of a different character from, those of plant viruses hitherto examined in the electron microscope. The present study was undertaken to obtain evidence …

Factors Governing The Retention Of Starches Added To Pulp In The Beater, Gordon J. Gill

Paper Engineering Senior Theses

Introduction

The information presented in this literature survey was obtained through Western Michigan College Library, Kalamazoo Public Library, St. Regis Central Laboratory, and Kalamazoo Vegetable Parchment Research Library.

The following survey is the result of twelve weeks of library research and was done in accordance with the methods and rules prescribed by Course 436A, Pulp and Paper Technology, Western Michigan College of Education.

Considering retention, from a general point of view, we find in Webster's New International Dictionary that it is, "A retaining or holding fixed in some place or position; state of being kept in place." Sutermeister (20) gives …

Bulletin No. 344 - The Nutritive Value Of Range Forage As Affected By Vegetation Type, Site, And State Of Maturity, C. Wayne Cook, Lorin E. Harris

UAES Bulletins

Native ranges of Utah are extremely heterogeneous. Pronounced variations exist in soil, seasonal rainfall, temperatures, and altitude on most grazing areas. Rough topography and micro-climates on even individual grazing allotments present variable vegetation types and site conditions. Such variations account for the comparatively large number of species and variable nutritive content found in range forage.

The Influence Of Crop Plants On Those Which Follow V, Theodore Eugene Odland, Robert Smith Bell, John B. Smith

Special Collections (Miscellaneous)

This is a study of the effect which crop plants have on the growth and yields of those crops which follow. The study began in 1907; this bulletin reports the results from 1930 to 1942. Millet, mangels and rutabagas generally seem to be harmful to crops which follow them. Carrots, mangels and millet were least favorable of all crops to mangels. Potatoes did poorest when following potatoes, rutabagas, or millet. Rutabagas yielded low following rutabagas, mangels and millet. Onions were unfavorably affect by preceding crops of mangels, cabbage, or rutabagas. There is no simple explanation for the effect of crops …

Distribution Of Mayfly Nymphs (Ephemeroptera) In Streams Of Dallas County, Texas, Louis E. Moore Jr.

Field and Laboratory

Although mayflies are of common occurrence in the Southwest, but little work has been done here on them. Most investigations on this group of insects have been done in New York, the Great Lakes Region, and Canada. Some work has been done in the Rocky Mountain area, and also along the Atlantic coast. Berner (1950) has published an extensive work on the mayflies of Florida. This is the first major work in this field since the book, Biology of Mayflies, by Needham, Traver, & Hsu (1935). Besides these, many minor papers on this group have appeared; but for Texas only …
