A Microscopic Study Of An Early Pennsylvanian Flora From The Manning Canyon Shale, Utah, Max W. Blaylock

Theses and Dissertations

The Manning Canyon Shale on the eastern slope of Lake Mountain in Utah County, Utah contains an Early Pennsylvanian flora within its upper shales. Many of these fossils appear to be new species. A microscopic study of the tissue remains can be of value in the further classification of these fossils. Selected fossils were macerated in hydrofluoric acid, and the residues were examined microscopically for tissue remains. Objects identified as fossil tissue remains were found in twenty five of the forty-eight specimens examined. Fibers, fiber tracheids, tracheids, and spores were isolated from fossils identified as Calamites. The spores were possibly …

A Phytosociological Study Of Coprophilous Ascomycete And Basidiomycete Communities From Santaquin Canyon, Utah, A. Clyde Blauer

Theses and Dissertations

Numerous reports have been published on the taxonomy and distribution of the coprophilous Ascomycetes and Basidiomycetes. No known quantitative work has been done, however, on the succession and structure of the communities formed by these higher fungi. This research was undertaken to study those two phases of the ascomycete and basidiomycete communities which grow and fruit on cow dung collected from Santaquin Canyon, Utah.

A Survey Of The State Of Utah For Areas Infested With The Stem Nematode Of Alfalfa, Dwayne R. Buxton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant nematodes belong to a large group of invertebrates known as round worms, They derive their name from the Greek word "nema," meaning thread. In literature some authors refer to nematodes as nemas. In England and many parts of the United States, plant-parasitic nematodes are called eelworms.

While some damage to plants results from mechanical injury, salivary secretions injected by the nematode into the plant are usually the major cause of damage. Experiments conducted in the first part of the present century have demonstrated large differences in plant growth in soil infested with nematodes and soil freed of nematodes by …

Existing And Potential Outdoor Recreation Resources In Bear Lake Valley, Utah And Idaho, Dennis H. Black

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Providing adequate outdoor recreational opportunities to the public is now a national problem. Of the many influences affecting the demand for recreation, increased income, population increase, sociological changes, and rapidly increasing technological developments are the more important. In the face of these factors, we must plan better to insure sufficient future needs. This will require evaluation and development of many recreation opportunities.

The Bear Lake are of northeastern Utah and southeastern Idaho is situated along U.S. 89 and within close driving distance of much of Utah's population. Up to the present there has been little orderly or planned development of …
