A Taxonomic Study Of The Catostomidae Of Utah Lake With Notes On The Fish Population, Lyle Junior Lowder
A Taxonomic Study Of The Catostomidae Of Utah Lake With Notes On The Fish Population, Lyle Junior Lowder
Theses and Dissertations
During the period from October 1950 to March 1951 a study of the taxonomy of the Catostomidae of Utah Lake was undertaken. Throughout this study information was collected on the numbers of suckers taken by some of the fisherman. From the data gathered it appears that the three species of Catostomidae cringinally named from Utah Lake are still there. The external morphological features of these fish are not recognizable unless they are observed very carefully. The most outstanding external characteristics used to differentiate the species are the mouth, lips, papillae on the lips and the general shape of the head. …
Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy
Ecology Of Passerine Birds Wintering At Utah Lake, Joseph R. Murphy
Theses and Dissertations
During the period of October to April of the winter of 1950-51, an ecological study was undertaken of a population or passerine birds wintering in a segment of the Utah Lake Shore. Available winter weather data indicated that although such factors as precipitation, temperature, and wind may often be severe, they are not critical enough to prevent a fairly large population of passerine birds from spending the winter months in the study locale. Five fairly distinct plant communities can be recognized in the area. There is evidence which indicates that certain passerine bird species are especially dependent on a particular …
Some Economic Aspects Of The Fluid Milk Industry Of Nebraska, Kenneth E. Anderson
Some Economic Aspects Of The Fluid Milk Industry Of Nebraska, Kenneth E. Anderson
Department of Agricultural Economics: Dissertations, Theses, and Student Research
Most citizens of Nebraska, especially the dairy farmers who produced milk for city consumption, are currently concerned with the problem of marketing fluid milk.In Nebraska and all over the United States, sales of wholesale milk farmers have been increasing for the past 15 years, while cream sales to creameries have been decreasing.
Production of milk in Nebraska is greatest in the eastern part of the state.Likewise, consumption is concentrated in Eastern Nebraska. This is most likely due to Eastern Nebraska’s highly concentrated population as well as the most favorable farm conditions for dairy cows.
Most of the bottled milk in …

An Ecological Study Of The Utah Sculpin Cottus Bairdi Semiscaber In Logan River, Utah, William Merle Zarbock
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The study of the Utah sculpin Cottus bairdi semiscaber, or Rocky Mountain bullhead as it is known locally on Logan River, Utah, is primarily one of determining its relation to game fish. Field work for this study began in 1949 and continued to March of 1951. Numbers of the Utah sculpin on Logan River have been estimated to be as high as 150 per tenth mile of stream. The larger populations are in the area of the third impoundment on Logan River and downstream.

An Economic Study Of Rats (Genus Rattus) In Cache County, Utah, John Vincent Bruce
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The most destructive animals in the world are rats (Rattus sp.). The annual destruction caused by rats in the United States is not known. but it has been estimated to be $189,000,000, according to Silver (1942) of the United States Fish and Wildlife Service. Silver states that our nation’s farmers lose approximately $6,000,000 annually. Rats not only eat vast amounts of food meant for human and livestock consumption, but they contaminate and waste as much or more than they eat. Rats are able to gnaw into buildings, grain bins, and other places were food and shelter are available to …

The Opercular Bone As An Indicator Of Age And Growth Of The Carp Cyprinus Carpio Linnaeus, William J. Mcconell
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
As part of an investigation of the non-game fish resources of Utah, a study of the age and growth rate of the carp was instituted. A preliminary investigation indicated that the opercular method was superior to several other methods of determining age and growth in the carp. Age and growth were calculated from the opercular bones of 330 carp collected at Ogden Bay Refuge in 1950-51. Distances to annuli were measured directly. The relationship between the posterior radius of the opercular bone and the standard length of the carp was curvilinear. Past growth was calculated with a logarithmic nomograph. Expected …

Theses and Dissertations
This study is concerned with a critical analysis of species and subspecies of Uta stansburiana as it occurs in the Eastern Great Basin. In this study Urosaurus ornatus wrighti is also briefly discussed since it was until recently considered a member of the genus Uta and since it extends in the area which has been dealt with in this thesis. This problem necessitated study of large series of lizards in order to work out subspeciation. The material from the Brigham Young University collection and the specimens collected by the author total 520. After recording dorsal scale counts, prefrontal scales, keelation …
The Effect Of Common Contaminants On Cheese Starter, Ivan R. Miller
The Effect Of Common Contaminants On Cheese Starter, Ivan R. Miller
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Starter is the "heart" of the cheese making industry. Only by proper handling of starter can good quality cheese be made. The economic loss from contaminated starter may prove disastrous to a cheese plant if proper corrective measures are not taken.
Milk usually contains a variety of bacteria. Under plant conditions some of these bacteria get into the mother starter or bulk starter unless extreme caution is used. Comparatively little is known about how one organism influences another when grown in milk. This problem is important in the cheese industry.

Age And Growth Of The Green Sunfish Lepomis Cyanellus Rafinesque In Northern Utah, Young E. Wright
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The green sunfish Lepomis cyanellus Rafinesque is a member of the sunfish family Centrarchidae. Curtis (1949) states that all members of the sunfish family are native only to North America, and are primarily warm-water fish. According to Jordan and Evermann (1934) the green sun-fish is generally abundant in all suitable waters from central Ohio and Indiana to the Rio Grande. Forbes and Richardson (1920) give the general distribution of the green sunfish to be from the Great Lakes to Mexico, the Mississippi Valley, and everywhere in small sluggish streams except east of the Alleghanies and in Canada. The green sunfish …

Effects Of Aureomycin In Milk Used For The Manufacture Of Cheese, James A. Banghart
Effects Of Aureomycin In Milk Used For The Manufacture Of Cheese, James A. Banghart
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Importance of project:
In recent years many antibiotics have come to the foreground as a treatment for mastitis. Aureomycin is one of the more recent antibiotics that has been used for this purpose.
Aureomycin has been reported to be successful in curing some types of mastitis, but milk produced by cows that have been treated with Aureomycin does not act normal in the cheese manufacturing process. The most noticeable effect in milk from cows treated with Aureomycin has been slow or complete cessation of acid production by bacteria in cultured dairy products; this has been especially true in the cheese …
Reactions Of The Rocky Mountain Muskrat Ondtra Zibethica Osoyoosensis (Lord) To Drought Conditions At Ogden Bay Bird Refuge, Utah, Edward V. Saunders
Reactions Of The Rocky Mountain Muskrat Ondtra Zibethica Osoyoosensis (Lord) To Drought Conditions At Ogden Bay Bird Refuge, Utah, Edward V. Saunders
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Perhaps no mammal on the North American Continent has received more attention in the literature than the muskrat (Ondatra spp.), but little of this material pertains to the reactions of muskrat populations to drought conditions. The author was unable to find any literature containing information on the reactions of the Rocky Mountain muskrat Ondatra zibethica osoyoosensis (Lord) to drought conditions in Utah. This information is of vital importance in formulating muskrat management programs in the State.
On many farms the muskrat population represents the greatest cash value of any kind of wildlife, and they utilize swamp areas and marshlands …

The breed association are continuously confronted with the problem of properly identifying animals for registration. The method of identifying the broken color breeds, such as Guernseys, Holsteins, and Ayrshires, is by a sketch of the color patterns which accompanies the application for registration. This has been fairly successful, but due to the poor drawing ability of the applicant approximately twenty percent of animal markings and sketch do not resemble each other to establish identity. The solid colored breeds use brands or tattoo marks in the ear which are not entirely satisfactory since these are artificial and can be applied in …

The Status Of Beavers In The Delta Area Of The San Joaquin River, San Joaquin County, California, 1950-1951, Delbert David Cram
University of the Pacific Theses and Dissertations
The term “delta area” refers to a region roughly 40 miles long and 15 miles wide situated 65 miles east of San Francisco Bay where the San Joaquin and Sacramento Rivers join and enter Suisun Bay. The waterways in this area are fresh water from these rivers, but they are affected by the ocean tides and to some extent by the salinity of the ocean water. The rgeion ecompasses about 507,000 acres, most of which has been reclaimed for agricultural purposes by the construction of levees to contain the tides and high waters. The word “islands” is used locally to …
