Reports From "Drought Front" Tell State Or Vegetation, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Development of the natural prairie vegetation is an excellent indicator of the intensity of drought. The extreme drought of 1934 left many bare areas in the grasslands and all but swept away most of the least drought-resistant species. The dry early spring and later summer of 1935 witnessed great increases in needlegrass, western wheat grass, and the invasion of a host of weeds. The favorable spring of 1936 promoted an abundant growth and emphasized the great changes in the prairie flora.

Bulletin No. 272 - Transmissibility Of Bang's Disease Among Dairy Cattle In A Utah Dairy Village, D. E. Madsen, O. G. Larsen

UAES Bulletins

For a number of years it has been generally recognized that one of the most satisfactory methods of controlling Bang's disease in dairy cattle is to locate spreaders by means of the agglutination test and to eliminate them from the herd. The success of such a plan in relation to Utah dairy herds was not clearly understood because of the physical farm set-up peculiar to many communities in this state. The village of Hyde Park where this study was made is organized on such a community basis. Usually, a house and livestock buildings are constructed on the town lot, consisting …

The Reptiles Of Cherokee County, Kansas, Myron Alec Hurd

Electronic Theses & Dissertations

Cherokee County has an area of 585 square miles. The greater part is covered with hydrophytes and mesophytes, but there are some Xerophytic areas. A large part of its area is covered with typical prairie grassland. Thickets of plum, sumac, persimmon, hawthorne, blackberry, and buck brush occur in pastures and wastelands. Along the streams may be found the elm-ask-oak assocations and other plants. Along the embankments may be found blackberry, sumac, and wild rose. Surrounding the ponds and marsh areas are rushes, reeds, button willows, and willows.

The mean annual temperature is 56 degrees fahrenheit. The three summer months average …

Pigment Migration In The Eye Of Forbesichthys Papilliferus, Harld Welborn

Masters Theses & Specialist Projects

Previous studies conducted in these laboratories showed the pigment in the eye of Forbesichthys papilliferus, when exposed to light, migrated from the stratum pigmenti into the layer of rods and cones. It was thought advisable to investigate this matter further. The following lines of investigation were conducted, viz:

1. to determine the rate at which the pigment migrates from the stratum pimenti into the layer of rods and cones when exposed to sunlight;
2. to determine the rate at which the pigment migrates from the stratum pigmenti into the layer of rods and cones when exposed to artificial light; and
3. to determine …

A Study Of The Stem Anatomy Of Aristolochia Sipho A., Rudolph F. Dobry

Bachelors’ Theses

Plant anatomy has been studied for over 265 years. The discovery of the plant cells by Robert Hooke in 1665m stimulated studies in regard to these structures.

A Further Study Of Utah Asilidae, D. Elmer Johnson

Theses and Dissertations

This study is based on a similar study made by Claudeous J. D. Brown in 1928, and published in 1929. The species he used have been rechecked, and additional ones have been studied. The species considered in this study represent three of the four subfamilies of North American Asilidae. These three subfamilies are Dasypogoninae, Laphriinae, and Asilinae. This study is limited to those species in the Brigham Young University Collections, and to species recorded in print. No claim is here made that all the forms inhabiting the state have been discovered, in fact the writer is well aware of the …

The Development Of The Embryo Of Iris Missouriensis Nutt, C. Eugene Larsen

Theses and Dissertations

There is but a single species of Iris native to Utah. This is Iris missouriensis Nutt. This plant was chosen for investigation because of its possible significance and because material of this species was readily available. The embryo of Iris missouriensis Nutt. shows some resemblance to the Lily type in its development of an irregular dividing suspensor. It also resembles the Orchid type in the usual development of sixteen cells before the dermatogen is cut off. In general development, however, the writer believes it to have an embryo sequence more similar to the Alisma type than to the dexcriptions given …

The Flora Of The Tasco Lake Region, Sheridan County, Kansas, Raymond W. Darland

Master's Theses or Doctor of Nursing Practice

It has been customary in writing theses dealing with taxonomic problems to collect data from an entire county. Having had occasion to collect botanical specimens from the Tasco Lake for work in biology at the Sheridan High School, the wealth of plant life to be found here became apparent. The area ranges from xerophytic forms on the uplands to the hydrophytic forms in the lake and marshes. Many of the latter have never been reported from Western Kansas. Collections in preserving fluid were made of the water forms found and specimens of the landforms were mounted on regulation-sized sheets properly …

The Effect Of Variation In The Calcium-To-Phosphorus Ratio On The Utilization Of Nitrogen, Calcium, And Phosphorus By The Growing Chick, C. W. Ackerson, M. J. Blish, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. Three groups totaling 123 chicks were fed accurately known amounts of rations containing 0.9, 1.5, and 2.3 per cent of calcium with liberal provision of the antirachitic factor so that conditions for assimilation and deposition were favorable. 2. By means of the comparative slaughter test the retention of ingested nitrogen was found to be about 37 per cent, and that of phosphorus about 28 per cent in the three lots. 3. With 0.9 per cent calcium in the ration, 35 per cent of that ingested was retained; at a level of 1.5 per cent calcium, 24 per cent was …

A Study Of Some Phases Of The Gametophyte Of Preissia Commutata Nees, Marion Steuber

Bachelors’ Theses

The beginnings of the exact knowledge of the Hepaticae dates from the work of Hofmeister, who in 1350 to 1362 published important investigations on them. He discovered the egg cell in the archegonium, traced the sperm to the surface of the egg and showed that it was fertilized by the sperm.

Spermatogenesis Of The Albino Rat (Nus Norvegicus Albus), Norman A. Frankenstein

Bachelors’ Theses

This thesis deals with the inquiry opened by the fundamental discovery that the gamete nuclei, and hence, the two parents from which they are respectively derived, con­ tribute each a haploid or single group of chromosomes to the fertilized egg. Each act of fertilization doubles the gametic number of chromosomes; yet the number of characteristic of the species remains constant from generation to generation. Somewhere in the life cycle, accordingly, the diploid or somatic number must be reduced by one-half to the haploid or gametic number. The first explanation was that reduction took place by some process of degeneration or …

Bachelors’ Theses

Histological Study Of The Structure Of The Testis Of Rana Pipiens, John L. Friedl

Bachelors’ Theses

All the living organisms, be they plant or animal, act as a unit which implies that the various anatomical and physiological systems are coordinated either for the benefit of the Individual itself or for the maintenance of the spe­cies. For convenience sake, the individual is divided into a digestive,. respiratory, circulatory, nervous, muscular, and skeletal systems; but there is one system which although of some value to the individual is primarily adapted for the production of other individuals, and this is the reproductive system.
