The Arid Lands Revisited, 100 Years After John Wesley Powell, Thadis W. Box

Faculty Honor Lectures

presented his Report on the Arid Lands of the United States with a More Detailed Account of the Lands of Utah to Secretary of the Interior Carl Schurz. The report was not so much a careful scientific report, but a distillation of Powell's experiences in the arid regions and a compilation of his recommendations. The paper "was less a report than a program - even, some western congressmen would begin to say, a manifesto, a revolution" (Stegner 1962). Stegner wrote:

It would ultimately be recognized as one of the most important books ever written about the West, and it was …

The Impacts Of Agriculture And Pastoralism On Wildlife In The Sudan, Fraser Tong Kuotwel

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This report describes the effects of agriculture and pastoralism on wildlife resources in the Sudan. For centuries people in the western and southern Sudan have been earning their living through shifting cultivation and pastoralism. Being one of the agrarian countries of Africa, the Sudan is rapidly undergoing a transition from shifting cultivation to mechanized farming, in order to provide enough food for its rapidly growing human population, and to supply other Arab countries with the surplus. Mechanized farming and water associated development projects have great impact on wildlife resources, ranging from the destruction of wildlife habitat to the isolation of …

Seasonal Course Of Root Respiration In Atriplex Confertifolia, Richard S. Holthausen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Root respiratory response of mature Atriplex confertifolia plants growing in established communities was measured during two growing seasons using freshly excised root segments and gas chromatography techniques. Respiratory response at fixed test temperatures changed significantly during the growing season, and this pattern of respiratory adjustment varied for root segments located at different depths in the soil profile. Respiration measured at a constant test temperature was highest during early sumner, and declined to minimum values in late summer and fall. Root segments taken from the top 30 cm of the soil profile displayed peak activity several weeks before root segments from …

The Effect Of Four Mine Spoil Treatments On The Seedling Water Relations Of Two Plant Species, Lorraine K. Van Kekerix

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Surface mines in mountainous areas cause environmental deterioration at lower elevations in the watershed. The most successful long term solution to the downstream problem is revegetation. However, mine spoils are low in essential plant nutrients, have low water holding capacity, and are often acidic. These factors limit plant colonization. Plants must also be adapted to the environmental conditions of high elevations.

At the McLaren Mine, }1ontana, at 2800 m, it was observed that seedlings on revegetation plots were desiccated, indicating possible water deficits. Field and growth chamber studies were carried out to determine the effects of some spoil ameliorating treatments …

Blackbrush utilization levels averaged 30, 16, and 6 percent (545, 367, and 147 kg per hectare) for the heavily, moderately, and lightly browsed pastures, respectively; removal rates of 77, 38, and 19 percent (1164, 582, and 291 kg per hectare) were projected.

Statistically significant differences in body weight loss (P=0.052) were noted for goats browsing in different replications. Goats lost an average of 14 and 19 percent of body weight in replications one and two, …

Coyote-Food Base Relationships In Jackson Hole, Wyoming, John L. Weaver

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I measured three variables of coyote-food base relationships in Jackson Hole, Wyoming, during the period July, 1973, to July, 1975. Field work provided estimates of relative coyote and prey abundance as well as observations on coyote feeding behavior during winter. Laboratory analysis of 1,500 coyote scats revealed feeding patterns while feeding trials with captive coyotes allowed refinement in interpretation of scat analysis.

Deer mice and chipmunks comprised most of the rodent biomass captured in traps in the fall, while ground squirrels accounted for much of the rodent biomass in the spring. Field voles declined from 1973 to 1974 throughout much …

Rodent Density And Species Composition In The Snake River Birds Of Prey Natural Area, Idaho, Jon R. Montan Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rodent densities were estimated in the major vegetation types of the Snake River Birds of Prey Natural Area in 1975 and 1976 by a combination of live-trapping and kill-trapping. Only deer mice (Peromyscus maniculatus) were numerous enough to permit reliable density estimates. Relative densities of other rodent species were indicated by kill-trap capture rates. Densities of deer mice correlated well (r = 0.99) with kill-trap capture rates. The use of kill-trapping in place of live-trapping in 1976 permitted extensive sampling throughout the 1930 km² study area. Differences were found among the major vegetation and land-use types in …

Occurrence Of Four Major Perennial Grasses In Relation To Edaphic Factors In A Pristine Community, Edgar F. Kleiner, K. T. Harper

Canyonlands Research Bibliography

The ecology and phytosociology of a virgin grassland community (Virginia Park, Canyonlands National Park, Utah) have been investigated. Based on the use of C √ó F index, Hilaria jamesii and Stipa comata are the most abundant of the four major perennial grasses. Oryzopsis hymenoides and Sporobolus cryptandrus are less abundant in decreasing order. The sites dominated by Hilaria are characterized by soils with finer texture, slightly warmer average temperature and higher surface K+ and organic matter compared to sites dominated by Stipa comata. In addition, frequency of both vascular and cryptogamic species is greater on sites dominated by Hilaria.

Soil Properties In Relation To Cryptogamic Groundcover In Canyonlands National Park, Edgar F. Kleiner, K. T. Harper

Canyonlands Research Bibliography

A comparative study was made of the soils of a virgin grassland and an adjacent grazed area in Canyonlands National Park. Soils from the virgin site were finer textured than those of the grazed area, and the surface 5 cm contains a significantly lower amount of calcium. In addition, the surface 5 cm of the virgin site contains significantly greater amounts of phosphorus, potassium, and organic matter. Subsurface soils in the two parks are less dissimilar. Cryptogams on the virgin grassland appear to have an important influence on chemical characteristics of the surface 5 cm of soil. The difference in …

A Study Of Feasibility Of State Water User Fees For Financing Water Development, Daniel H. Hoggan, O. W. Asplund, J. C. Anderson, D. G. Houston

Reports

Water user fees imposed by a state on major water uses is a possible new alternative source of state water development funds. A fee, similar to an excise tax, might be charged for the use of the water resource per se, which in a number of states is declared to be the property of the public of the state. States generally have not employed such fees as a source of operating funds for water agencies or of development capital. Only in the area of water based recreation-fishing, coating, camping, etc.—have states extensively employed user fees. The revenues from these fees, …

Seedability Of Winter Orographic Storms In Utah, Geoffrey E. Hill

Reports

The primary objective of this research has been to collect and analyze data from (randomized) seeded and unseeded winter storms over the Wasatch Mountains for the purpose of developing and designing cloud seeding technology. Two field programs were conducted sequentially; the first was done by airborne seeding and the second by seeding from mountaintop generators. Analysis of precipitation estimators based upon radar and/or rawinsonde data and target precipitation show that increased precipitation due to seeding may occur under certain meteorological conditions. Favorable conditions were found when the supercooled water concentration as measured by aircraft icing rates was high. Precipitation in …

Series Intermittent Sand Filtration Of Wastewater Lagoon Effluents, David W. Hill, J. H. Reynolds, D. S. Filip, E. J. Middlebrooks

Reports

Previous researches have found single stage intermittent sand filtration to be a feasible and economic means of upgrading wastewater lagoon effluent to meet future standards. However the major constraint on their use has been the length of the filter runs. Laboratory scale and pilot-scale series intermittent sand filtration of wastewater lagoon effluents has been found to substantially increase the length of filter runs as well as produce a high quality effluent able to meet future standards. Higher loading rates were round to be possible with series intermittent sand filtration. The operation consistently produced an effluent meeting present Utah “Class C” …
