Use Of Selected Macroinvertebrates As Indicators Of Sedimentation Effects On Huntington River, Utah, Michael Kenneth Reichert

Theses and Dissertations

Benthic macroinvertebrate communities of Huntington River, Emery County, Utah were studied to determine effects of sedimentation from construction of Electric Lake Dam, a state highway, and two bridges. Approximately 900 benthic samples were collected from riffle areas above, in, and below the construction zone from January, 1971 to December, 1973. Two settling basins below construction sites were effective in limiting scouring of downstream communities. Heavy silt deposition was limited to a 1-km stream reach. Number of indicators, density, and biomass were reduced in the construction zone during periods of sediment input. During periods of scouring, density and biomass were reduced; …

The Algae Of Huntington Canyon, Utah, Carol Jean Endsley

Theses and Dissertations

A taxonomic study of the algae of Huntington canyon, Emery County, Utah, was conducted from March 1971 to April 1972. The algal flora of this cold, fast-flowing, hard-water mountain creek consisted of ninety-five genera, one hundred ninety-six species, twenty-nine varieties, and two forms. This diverse flora was dominated by many different species with usually rather few individuals of Achnanthes, Cymbella, Diatoma, Gomphonema, Lyngbya, Navicula, Nitzschia, Oscillatoria, Synedra, and Ulothrix.

Perception And Land Use: The Case Of The Mormon Culture Region, Lester D. Campbell

Theses and Dissertations

Since the first man perceived and used his environment, there has existed a reciprocal man-land relationship. The physical environment provides opportunities for man's use and also sets limitations. Man's perception and use of his environment is greatly influenced by his culture, which consists of past experience, technology, attitudes, and needs. It is these factors that determine what a man will see as possibilities in land use, and how he will use his environment.

In the case of the relic Mormon Culture Region, Mormon religious beliefs highly influenced perception of the environment. Most visual geographical features of the landscape in the …

A Quantitative And Ecological Survey Of The Algae Of Huntington Canyon, Utah, Lorin E. Squires

Theses and Dissertations

A quantitative and ecological study of the algal flora of Huntington Canyon, Emery Co., Utah was conducted from March 1971 to April 1972. Data were collected concerning net plankton, nannoplankton, periphyton and visible attached algae. Certain physical and chemical parameters in the waters of Huntington Creek and a small pond along its course also were measured. The algal flora of Huntington Canyon contains a wide diversity of genera and species. Diatoms are the main constituent of the flora of this stream throughout the year. Hydrurus foetidus is prevalent in the creek in Huntington Canyon from late winter to early summer, …

The Stratigraphy And Economic Potential Of Permo-Pennsylvanian Strata In Southwestern North Dakota, Harold C. Ziebarth

Theses and Dissertations

This study of the Fermo-Pennsylvanian Minnelusa Group in North Dakota was designed to clarify the stratigraphy, illustrate association of depositional environments, and to relate the geologic history and economic potential of these strata.

The Minnelusa Group is defined here to include strata above the unconformity on the Madison and Big Snowy Groups and below the Opeche Formation. The Minnelusa Group in North Dakota contains the Tyler, Alaska Bench, Amsden and Broom Creek Formations. The Amsden has been divided into three marker defined lithozones designated, in ascending order, Medora, Dickinson, and Bismarck.

Drill and core samples were examined and described interpretively …
