Consumer Profile Differences Among Utah And Idaho Boaters, Thomas D. Singleton
Consumer Profile Differences Among Utah And Idaho Boaters, Thomas D. Singleton
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The purpose of this study was to describe and evaluate the consumer characteristics of boaters in Utah and Idaho. This has entailed a descriptive analysis of boater's socio-economic profiles, facilities and equipment, preferences and attitudes, and activity patterns.
Concomitantly a test of the hypothesis that boating is not a homogenous recreational activity was attempted. Two statistical analyses were carried out. The first test was to determine whether the profiles of boaters having different activity specialities differed. This was accomplished by finding the means of selected boater characteristics (i.e., income, children, length of boat) for each boating speciality. The L.S.D. multiple …
Plant Demographic Studies Of Tall Threetip Sagebrush-Grass Vegetation On The Eastern Snake River Plains, Idaho, Kenneth Harold Rea
Plant Demographic Studies Of Tall Threetip Sagebrush-Grass Vegetation On The Eastern Snake River Plains, Idaho, Kenneth Harold Rea
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
It has commonly been assumed that grazing decreases the longevity of plants, however, very few studies address this question. Knowledge of mean age, longevity and other aspects of population dynamics would help improve estimates of productivity and nutrient cycling and aid understanding of range condition and trend. These data would also aid in developing a theory of community organization and control.
As a step toward these ends, pantograph records from twelve 1 m2 plots established at the U. S. Sheep Station on the Snake River Plains of southeastern Idaho between 1923 and 1935 were examined. The plots were mapped …
Demographic Analysis Of A Utah-Idaho Coyote Population, Jeffrey J. Knudsen
Demographic Analysis Of A Utah-Idaho Coyote Population, Jeffrey J. Knudsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
I estimated various demographic parameters of the coyote population in Curlew Valley, northern Utah and southern Idaho, during the period August 1972 through September 1974. Field work provided estimates of relative and absolute coyote densities and established causes of coyote mortality. Laboratory analyses of 866 coyote carcasses supplied information on sex and age ratios, ovulation frequencies, pregnancy rates, and litter sizes.
Annual ovulation frequencies and pregnancy rates for the entire population varied from 70 to 92 percent and 57 to 88 percent respectively. Age-specific ovulation frequencies varied from 63 to 91 percent, respectively, for pups and adults. Similarly, age-specific pregnancy …
