The Relationship Between Antibody Titer And Resistance To Staphylococcal Synovitis, Keith Mckay Budge

Biology

The turkey industry is one of the major agricultural pursuits in the state of Utah. Synovitis is one of the most costly diseases in the turkey industry and causes considerable economic loss to the growers. Although much research has been done on synovitis, little is known of the serology of the disease. This paper consists of a study of antibody titer by use of complement fixation and agglutination tests during the course of vaccination of turkeys, as related to survival, crippling, and death. A field study of twenty birds is reported to show the relationship of antibody titer of apparently …

The Description And Biology Of Bracon Lissogaster, A New Parasite Of The Wheat Stem Sawfly, Kenneth B. Maughan

Biology

Bracon lissogaster Muesebeck, a new parasite of the wheat stem sawfly, Cephus cinctus Norton, was first reared by the author from sawfly larvae at Choteau, Montana, during the summer of 1950. A comparison with known parasites of this host indicated it to be different than any parasite recorded in the literature. This parasite was studied by Mr. C. F. W. Muesebeck, In Charge, Division of Insect Identification, Bureau of Entomology and Plant Quarantine, Washington, D. C., who is the leading specialist of this group. He reported this parasite as being an undescribed species. The purpose of this study is to …

Life History Studies Of The Snipe Fly Atherix Variegata Walker, Wallace P. Murdoch

Biology

Atherix variegata Walker is a snipe fly (family Rhagionidae) of the Nearctic region associated with rapid streams in mountainous or semi-mountainous areas. Naturalists and sportsmen have frequently expressed interest in the large masses of eggs and females which can be readily observed in early summer on the undersides of bridges and on rocks and branches overhanging water. As one reads the fragmentary accounts of the biology of snipe flies it becomes apparent that a need for life history studies exists for most genera of this family. Although the life history of Atherix variegata is better known than that of many …

A Brief Survey Of Biotic Distribution And Its Physical Environment In A Transect Across Yosemite Valley, California, Wayne W. Bryant

Biology

Yosemite Valley, though famed for its scenic beauty and geologic history, is also of outstanding biological interest, especially to nature-lovers and scientists. A favorable climate produces a vast variety of life forms. The varied physiography of the area effects a great diversity of plant communities and vertebrate animal habitats. The number of plant and vertebrate animal species is particularly large for so small an area. The distribution of these species should reflect both general and local environmental conditions. In this paper it is the endeavor of the writer to (1) survey briefly the distribution of plants and vertebrate animals within …

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

Soil Nitrate, Total Nitrogen And Organic Matter In Relation To Dry-Farming, Krishnappa Ramaiah

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Dry farming has been defined as production of useful crops, without irrigation, on lands that receive an annual precipitation of 20 inches or less. In some regions the term dry farming is applied to farming without irrigation under annual precipitation of 30 inches or less. Although there is no sharp demarkation between dry farming and humid farming, the term dry farming always means farming under difficulties due to limited annual rainfall.

Fertilizer Trials On Dryland Winter Wheat, I. G. Sampson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wheat is one of the major crops of Utah and for more than 50 years farmers have been raising wheat on the dry lands of the state. The system they use is known as the alternate cropping or crop-follow system and consists of one year of crop alternating with one year of clean cultivation known as fallow.

Wheat removes a considerable amount of the natural plant food elements from the soil each year. This is especially true of nitrogen. According to Bracken and Greaves (9) the original low supply of nitrogen in most Utah soils together with the depleting effects …

Age And Growth Of The Brown Trout Salmo Trutta Fario Linnaeus In Logan River, Utah, William Sigler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Logan River flowing southwesterly through the mountains of Cache County, Utah is comparatively cold to the mouth of Logan Canyon. The stream is characterized by steep gradient, a high velocity and relatively few pools. A total of 1053 brown trout were examined during the course of this study; 286 were retained for age and growth determinations. The body-scale relationship is L = 40.46 mm. + 0.44185R + 0.01908R² where L equals standard length in millimeters, and R equals scale radius times 80. The relationship of standard length to weight is described by the formula W = 0.000022 L …

The Food Of Pond Fish In Northern Utah, Robert L. Eberhardt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A series of ponds in northern Utah supplied mainly by artesian water was poisoned with rotenone during 1949-50. Four hundred and seventy-three fish were obtained for a food habits study, and of these fish, 423, or 89 percent, had food in their stomachs. The species studied were largemouth bass, green sunfish, common bluegill, and black bullhead. Largemouth bass had the widest variety of diet throughout the year but also had the highest percentage of empty stomachs. Green sunfish and black bullhead had the least diverse food habits. Twenty-nine different food items were recorded; those used most commonly were green sunfish, …

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.

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 …

Inheritance Of 16 Barley Characters And Their Linkage Relationships, Tejpal Singh Gill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The assignment of genetic factors to definite loci in the hereditary mechanism has been a great step in the progress of biology. Of the cereal crops, barley (Hordeum sp.), a crop of economic importance, offers a superior opportunity for genetic studies. Its adaptation to wide varieties of conditions, with a wealth of easily differentiated characters and only seven pairs of chromosomes, the barley plant provides excellent material for linkage studies.

Although there is a vast amount of literature dealing with inheritance in barley, yet knowledge of the subject is still very limited. The mode of inheritance of about one hundred …

Canal Seepage Loss Investigations In The Lewiston Area, Utah, Robert V. Thurmond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With population, industry, and irrigation ever increasing in the arid west, there arises new and greater demands for water. Much of the water now urgently needed is lost as seepage from the many miles of canals in the western states.

Rohwer and Stout (18) have estimated that in the western states from one-third to one-half of the water diverted for irrigation is lost before it reaches the farmers' fields. Of these losses, seepage probably accounts for the greatest loss. It is reported by the Bureau of Reclamation (14) that, of the 14,600,000 acre feet of water diverted on 36 projects …

Enemies Of Aspen, Clyde M. Christensen, Ralph L. Anderson, A. C. Hodson, Paul O. Rudolf

Aspen Bibliography

So long as aspen was considered primarily a weed species, there was little concern over the enemies which might injure or destroy it. Sometimes these enemies were actually considered "blessings in disguise. Now, however, that aspen not only is the most abundant "but also one of the most widely utilized tree species in the Lake States, there is increasing interest in anything that may affect its future supply. For that reason this brief summary of information on the enemies of aspen has been assembled.

Bulletin No. 343 - Utah Agricultural Experiment Station Biennial Report 1948-1950, R. H. Walker

UAES Bulletins

The objective of an agricultural experiment station is to help the farmer solve the technical problems of agriculture that he has neither the money, time, nor technical skill to solve himself. For sixty-two years now the Utah Station has been concerned with the problems peculiar to the state, problems of range management and of range cattle and sheep production, problems of fanning under dry land conditions, and problems of irrigation agriculture. Many problems have been solved. There is hardly a farm practice today that has not been influenced by the research of the agricultural experiment station. But new problems are …
