Turbidity - Suspended Sediment Relations In A Subalpine Watershed, Thomas A. Holstrom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of particle size distribution of suspended sediment vii upon a turbidity reading at a known concentration has been relatively quantified for stream bank materials on the Moccasin Basin - North Fork Fish Creek (MB-NFFC) Watershed, located in northwestern Wyoming. As expected, an increase in the median particle size in suspension results in a decrease of turbidity at a given concentration. The relationship derived correlates the particle size distribution of a chemically dispersed stream-bank material sample, with the Coefficient of Fineness for a mechanically dispersed portion of the sample.

Two Basic Methodological Choices In Wildland Vegetation Inventories: Their Consequences And Implications, Donald Alan Shute

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In designing inventories of wildland vegetation, two of the many basic methodological choices are: 1) whether data are collected, reduced, and stored in discrete classes or as continuous variables, and 2) whether data are gathered as general purpose variables to bear upon many questions, or as specific purpose variables optimized for only one type of prediction. The effects of these two choices on accuracy of vegetation inventories to predict plant community production were examined by comparing regression models built upon differing sets of independent variables "inventoried" from a common data base. Contrary to expectations, discrete variables of classified community types …

Effects Of Forage Availability On Voluntary Intake And Feeding Behavior Of Grazing Heifers, Anastasios S. Nastis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Forage intake by animals is an important factor in determining production of livestock products from rangelands. However, relatively little is known of effects of such forage variables as availability and distribution in space upon intake. Even less is known about how the grazing animal modifies its feeding tactics when confronted with diminishing or limited supplies of available forage and how such altered behavior may affect the animal's energetic cost for existence. Forage intake, body weight gain, grazing time and biting rate of Angus heifers was related to forage availability and plant height on semiarid crested wheatgrass rangeland during the late …

Estimation Of The Pantothenic Acid Content Of Foods Using A Microbiological Assay And A Radioimmunoassay, Joan Howe Walsh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Seventy-five processed and prepared foods commonly consumed in the United States were analyzed for pantothenic acid. The foods were analyzed using the traditional microbiological assay for the vitamin and using a new radioimmunoassay (RIA).

The preparation of food sample extracts for both assays was modified. After the food samples underwent enzyme hydrolysis, the food-enzyme mixture was dialyzed to obtain a clear extract for use in the assays. Previously, the food-enzyme mixture was poured through filter paper for clarification.

A very high correlation (r²= .937) between the results from the RIA and the microbiological assay was found. There was …

The sample was 191 two-parent, two-child families residing in Iron, Washington, and Salt Lake Counties. Urban/rural residence, wife's employment status, educational level of both the husband and wife, family income, religious activity, and the husband's occupation were studied in relation to household task allocation.

Eight hypotheses were tested. Husband's religious activity and wife's employment status were found to be related to a traditional pattern of household task allocation. There was a …

Estimation Of Floods When Runoff Originates From Nonhomogeneous Sources, David Ray Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extreme value theory is used as a basis for deriving a distribution function for flood frequency analysis when runoff originates from nonhomogeneous sources. A modified least squares technique is used to estimate the parameters of the distribution function for eleven rivers. Goodness-of-fit statistics are computed and the distribution function is found to fit the data very well.

The derived distribution function is recommended as a base method for flood frequency analysis for rivers exhibiting nonhomogeneous sources of runoff if further investigation also proves to be positive.

The Prior Distribution In Bayesian Statistics, Kai-Tang Chen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A major problem associated with Bayesian estimation is selecting the prior distribution. The more recent literature on the selection of the prior is reviewed. Very little of a general nature on the selection of the prior is formed in the literature except for non-informative priors. This class of priors is seen to have limited usefulness. A method of selecting an informative prior is generalized in this thesis to include estimation of several parameters using a multivariate prior distribution. The concepts required for quantifying prior information is based on intuitive principles. In this way, it can be understood and controlled by …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ogden Bay Waterfowl Management Area is one of many marshlands bordering the Great Salt Lake that are extremely important as breeding habitats for North American waterfowl. Salinity, both of surface and interstitial waters, is an important factor in maintaining a suitable habitat within the marsh. For this reason, a study was undertaken to determine the factors affecting the salinity of surface and interstitial waters. A small (approx. 100 acre) subunit was studied extensively to determine; 1) variations in surface water salinity with flowrate and water level; and 2) variation in interstitial water salinity with depth and location within the subunit. …

Information Transfer And Regulation In A Model Ecosystem With Environmental Stochasticity, M. Mckee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The concept of regulation in ecosystems has been given considerable attention in the ecological literature, but no formal treatment has been offered. This study proposes a rigorous definition of regulation which is derived from the mathematics of information and communication theory. A theoretical, mathematical equivalent of the definition is also offered which implies serious limitations as to the value of most traditional laboratory population studies and deterministic population models in understanding regulation in ecosystems. The empirical validity of this theoretical equivalence is tested through use of a competition model of two diatoms. Other observations concerning the relationship between environmental variability …

The investigation was part of a large scale project to determine minimum stream flow requirements for trout. The effects of time, habitat, depth and velocity on the distribution of benthic fauna were evaluated.

Samples of benthic invertebrates (146 total) were collected every 2 months at 8 stations on the river from November, 1975 through August, 1976. Representatives of 59 taxa were collected. Eight taxa comprised 90 percent of the mean annual community standing crop in numbers. Biomass was not dominated by any group …

Diffuse Irradiance In The Rocky Mountains At 40° Latitude, Brock Allen Lebaron

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of the parameters effecting diffuse irradiance in mountainous terrain was made. Ground/location parameters of site elevation, ground albedo, elevated horizon and surface tilt were examined under the pertinent atmospheric conditions of clear, polluted, overcast, and cloudy. Measured diffuse irradiance data used for comparisons were taken from fall 1977-spring 1979 at four sites located in northern Utah.

Diffuse irradiance varied with elevation according to the existing atmospheric conditions. For clear sky, diffuse irradiance decreased with elevation due to the shorter optical pathlength, thus less scatter of the direct beam. However, with completely overcast sky, diffuse irradiance increased with elevation. …
