An Analysis Of An Unilateral Reproductive Isolation Barrier In Secale L, Harold James Price

Theses and Dissertations

In the cross, S. cereale ♀ x S. africanum ♂, near normal seeds were formed. They showed 40% germination. In the reciprocal cross, S. africanum ♀ x S. cereale ♂, the seeds were dry, brittle, extremely shrivelled at maturity and none germinated. Reciprocal differences as sharp as those in crosses between S. cereale and S. africanum were not noted in crosses of S. cereale with S. montanum or with S. vavilovii. Seeds from the cross S. cereale ♀ x S. montanum ♂ showed 81% germination, whereas seeds from the reciprocal cross S. montanum ♀ x S. cereale ♂ showed 77% …

Model Study And Analysis Of The Flow Elements Of A Recirculation Mixing System, Albert Warren Berg

Theses and Dissertations

The term water clarifier as used in this text refers to a versatile water treatment unit which combines flocculation and coagulation, clarification and positive sludge removal in a single tank. Water clarifiers are very compact units which are being used in municipal and industrial water treatment for the removal of turbidity, algae, color, iron and silica; lime or lime-soda softening; magnesium precipitation; brine clarification; and waste water clarification with or without chemicals. Water clarifier units have found wide use in the sanitary field, providing high removals in the pre-treatment of sewage and in secondary sewage treatment through addition of coagulants.

A Swiss View On The American Civil War, Dr. Hans Rudolf Guggisberg

The Ecology Of The Western Spotted Frog, Rana Pretiosa Pretiosa, Baird And Girard: A Life History Study, Ronald Ladell Morris

Theses and Dissertations

Observations and collections on the breeding biology and life history of Rana pretiosa pretiosa Baird and Girard have been made in central Utah from 1962 to 1967. The frogs' activities were followed from their spring emergence untril the tadpoles metamorphosed and hibernated in the fall. Collections and observations were made at regular intervals through the entire period of summer activity. Data were gathered at the ponds and samples of the life history stages were taken to the laboratory where they were analyzed and studied. Emergence is normally during the middle of March. The males precede the larger females by three …

Ticks Of The Genus Haemaphysalis In The Western United States, Joe M. Merino

Theses and Dissertations

Two species of Haemaphysalis occurring in the western United States were studied with respect to geographical distribution, seasonal occurrence, host-parasite association and external anatomy and morphology. H. leporispalustris is widely distributed in the west. Abundant records for some states are lacking and should be provided to extend the knowledge of this tick's distribution.

Aquatic Phycomycetes Of Lily Lake, Hugh Macmillan Rooney

Theses and Dissertations

Lily Lake, a subalpine lake in the Wasatch National Forest Tl5, R9E, S31, of the Uinta Mountain Region, Utah, is located about one-half mile west of Trial Lake at an elevation of 10,000 feet. This Lake, which is one of the acidic, cold, lentic bogs characteristic of this area, has been selected for a taxonomic and seasonal distribution study of acquatic phycomycetes. This study is a beginning to our knowledge of the role of the fungi in the hydrobiology of Lily Lake and will supply the first information on record of the water molds of this area. The study identifies …

Physiological Variations In The Uinta Ground Squirrel (Citellus Armatus) In Relation To Seasonal Activity And Altitude, Marden Reed Kohler

Theses and Dissertations

The purpose of this investigation was to study the weight changes of selected internal organs to determine possible physiological variation occurring at six different altitudes ranging from 5,800 to 8,500 feetand during the summer season. This report was limited to the study of changes in the adrenal glands, kidneys, testes, heart and intestines. Electrocardiogram, heart and respiration rates were investigated also. These changes were statistically analyzed to determine possible seasonal differences along with any significant changes occurring at different elevations. The results of the study should in part overcome the lack of current experimental data for Citellus armatus.

A Study Of The Golden-Mantled Ground Squirrel (Citellus Lateralis) In A Sagebrush-Grass Community, Dennis E. Peterson

Theses and Dissertations

Golden-mantled ground squirrels (Citellus lateralis Say) typically inhabit coniferous forest regions, but they occasionally occur in desert shrub habitats. The principal purpose of this study was to observe activities of mantled squirrels in a sagebrush community, and to ascertain factors which contribute to their success in an unusually arid habitat. Squirrels of this community belong to the subspecies C. l. lateralis; however, intergradation between typical C. l. lateralis and C. l. castanurus is evident. This community is in the Wasatch Mountains at an elevation of 5,750 feet, and in the Upper Sonoran Zone. These three conditions were not previously recorded …

Investigations Into The Spawning Ecology Of The White Bass Roccus Chrysops, (Rafinesque) In Utah Lake, Utah, Frédérick Vinvent

Theses and Dissertations

Utah Lake, located in Utah County, north-central Utah, is one of the most important natural fishing lakes in the state. The spawning ecology of the white bass (Roccus chrysops) was studied in Utah Lake between 1964 and 1966. Gill nets and seining were the primary means of sampling. The spawning location was sampled every other day throughout the spring and early summer of 1966. Three major winter schooling areas were found: Provo Bay - Creer Access south to the mouth of Spanish Fork River, Lincoln Beach, and off Ludlow Barn. There appears to be extensive winter feeding and movement among …

Life History And Ecology Of The Colorado Chipmunk (Eutamias Quadrivittatus Hopiensis), Carl Eugene Wadsworth

Theses and Dissertations

Observations of reproductive behavior, growth and development of the young, food habits, habitat preference, and daily and seasonal activity patterns of the Colorado chipmunk are presented for the first time. The breeding cycle is as follows: mating occurs in late February or early March; the young are born in early to mid-April and first appear above ground in May, but do not reach breeding age until the following spring. There is only one litter of young per year. The mean number per litter was 5.7 for three litters born in captivity. The sex ratio of the animals born in captivity …

The Design Of A One-Man Terramechanism, Brent Charles Fryer

Theses and Dissertations

With the rebirth of special warfare in the last few years, the role of the individual soldier and of squad-sized units has been re-emphasized. Most guerilla-type fighting has been, is presently, and will most likely continue occurring in remote areas of the world. The terrain encountered may be tropical grasslands and canopy areas, or rugged mountains, inland waterways, swamps, mud flats and rice paddies. Other adverse terrain conditions are frequently encountered and must be crossed to accomplish the mission of the unit.
