Predation Of Upland Game And Its Management, Roger Wells
Predation Of Upland Game And Its Management, Roger Wells
Great Plains Wildlife Damage Control Workshop Proceedings
There is probably no greater topic that elicits greater emotion in public wildlife discussions than that of predation. A variety of groups each with their own particular special interest surround the topic.
Some advocate complete protection of predators on the premise that their activities merely result in a "balance of nature." The opposite viewpoint argue just as strongly for the total elimination of Predators of valued wildlife in order to have greater number for man's enjoyment.

Mule Deer Habitat Guidelines, Richard M. Kerr
Mule Deer Habitat Guidelines, Richard M. Kerr
United States Bureau of Land Management: Staff Publications
The purpose of this Mule Deer (Odocoileus hemionus) Habitat Management Guide is principally to assist BLM managers and biologists in planning for and managing mule deer habitat on public lands administered by the Bureau of Land Management. For many years Federal land management agencies have made the distinction between the Federal responsibility for managing habitat and the State prerogatives of managing native wild ungulate populations. Certainly the two are inseparably linked. These responsibilities, and up to now "symbiotic relationships", are probably best described succinctly in Title 43 of the Code of Federal Regulations Part 24.

All U.S. Government Documents (Utah Regional Depository)
Application of wastewater to the land has been designated a viable alternative for wastewater treatment by the Water Pollution Act Amendments of 1972 (PL 92-500). However, very little information is available concerning the long-term effects of applying wastewater to the land. The general objective of this study was to determine the long-term effects of employing secondary treated municipal wastewater as irrigation water. The study compared the quality of soils, crops, groundwater, and applied water to a site receiving normal irrigation water (control site) to a site (treated site) which had utilized seondary treated municipal effluent for irrigation water during a …

Vesicular-Arbuscular Mycorrhiza Influence Growth But Not Mineral Concentrations In Seedlings Of Eight Sweetgum Families, Richard C. Schultz, Paul P. Kormanik, W. Craig Bryan, G. H. Brister
Vesicular-Arbuscular Mycorrhiza Influence Growth But Not Mineral Concentrations In Seedlings Of Eight Sweetgum Families, Richard C. Schultz, Paul P. Kormanik, W. Craig Bryan, G. H. Brister
Richard C. Schultz
Seedlings of eight half-sib sweetgum (Liquidambar styraciflua L.) families were grown for 6 months in a fumigated soil mixture, with or without inoculum from a mixture of Glomus mosseae and Glomus etunicatus fungi, at levels of 140, 280, 560, and 1120 kg/ha of 10-10-10 fertilizer. All seedlings received three additions of 187 kg/ha of N during the growing season. Inoculated seedlings had significantly greater biomass, height, and stem diameters at each fertilizer level than nonmycorrhizal control seedlings. Significant differences in growth occurred between families in mycorrhizal plants. However, fertilizer did not significantly affect growth or nutrient uptake of the seedlings. …

Reproductive Modes Of The Least Chub (Iotichthys Phlegethontis - Cope), Marianne Crawford
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The reproductive biology of the least chub Iotichthys phlegethontis (Cope) was studied from June 1976 to March 1978. Fish from both field and laboratory populations of the Leland Harris Spring Complex, Juab Co., Utah were utilized in the study. Reproduction in 1977 occurred from April to July in the field population and from April through August in the laboratory population.
Reproduction was determined from gross examination and weight measurements of testes and ovaries, breeding coloration in males and diameter measurements of ova.
Males and females matured at about the same size, 28 to 30 mm TL. The number of mature …

Biology, Reproductive Potential And The Impact Of Fishing Pressure On The Bluegill Fishery Of Pelican Lake, Uintah County, Utah, Bob D. Burdick
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Certain aspects of the biology of two species of fish, bluegill (Lepomis macrochirus) and largemouth bass (Micropterus salmoides), and the assessment of fishing pressure upon the sport fishery of Pelican Lake, Uintah County, Utah, a 680 ha warmwater lake, were studied between April 1, 1976 and June 30, 1978. The growth rate of bluegills (sexes combined) was fairly rapid; the mean back-calculated total lengths from ages one through nine were 55, 112, 166, 194, 211, 229, 245, 256 and 259 mm. The growth of largemouth bass was 104, 194, 271, 316, 350, 405 and 416 mm …

Development And Validation Test Of A Mule Deer Habitat Rule, Glenn Gephart
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A mathematical description of Rocky Mountain mule deer (Odocoileus hemionus hemionus) habitat was developed and subjected to validation testing using correlation and multiple regression statistical techniques. Data were collected on a central Utah study area, which was divided into mountain and desert regions.
Data on deer utilization and several habitat components from 86 study plots visited in 1976 were used to develop a habitat rule. Data from 46 study plots visited in 1977 were used to test the accuracy of the rule. Deer utilization was determined from pellet group counts on 20 0.001 ha pellet plots at each …
Information Transfer And Regulation In A Model Ecosystem With Environmental Stochasticity, M. Mckee
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 …
Some Effects Of A Grazer, Hyalella Azteca On Ecosystem Level Properties In Aquatic Microcosms, Martin D. Werner
Some Effects Of A Grazer, Hyalella Azteca On Ecosystem Level Properties In Aquatic Microcosms, Martin D. Werner
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A study to determine some ecosystem level effects of an aquatic invertebrate grazer, Hyalella azteca, was performed in aquatic ix microcosms. Impact of the grazer was assessed in three general areas: 1) inorganic nutrient levels of the microcosm water column, 2) productivity and respiration of the biotic community, and 3) plant community composition in the microcosms.
The grazing amphipod caused inorganic phosphorus and nitrogen (except ammonia) levels to be elevated in the microcosms. The increase was due, at least partially, to excretion of nutrients into the water by the amphipod. The presence of H. azteca did not significantly …
Two Basic Methodological Choices In Wildland Vegetation Inventories: Their Consequences And Implications, Donald Alan Shute
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 …

Interrelationships Between Benthic Macroinvertebrates And Habitat In A Mountain Stream, John M. Payne
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A study to determine habitat differences of benthic macroinvertebrates was conducted on the upper Strawberry River, Utah. 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 …

Spectral Signature Studies For Application In Deer Census Using Remote Sensing Techniques, Maran C. Pate
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study was performed to determine the spectral signatures of deer and their natural background elements for censusing purposes. Consideration was given to atmospheric transmittance, acceptable flying weather, and terrain. Possible spectral bands between 0.3 and 14.0 μm were obtained (over a pathlength of 1500 feet at an altitude of 5000 feet) based upon atmospheric transmittance using the LOWTRAN 3B computer program. They are: 0.30 - 1.33, 1.49 - 1.79, 2.00 - 2.50, 3.00 - 3.16, 3.38 - 4.10, 4.59 - 5.05, and 8.00 - 13.33 μm, for transmittance greater than 75%. Weather conditions are favorable for flying and taking …
Effects Of Forage Availability On Voluntary Intake And Feeding Behavior Of Grazing Heifers, Anastasios S. Nastis
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 …
Ecotypic Differentiation Of Andropogon Virginicus L. In Relation To Strip Mine Spoil Banks, Valina Kay Hurt
Ecotypic Differentiation Of Andropogon Virginicus L. In Relation To Strip Mine Spoil Banks, Valina Kay Hurt
Masters Theses & Specialist Projects
Reciprocal plantings of populations of broomsedge, taken from an abandoned strip mine and from an abandoned farm plot in south central Kentucky, on strip mine spoil and abandoned field soil resulted in patterns of populations differentiation. Clonal plantings of populations from strip mine habitats and old field development appeared equal in height and biomass when grown on old field soils in both field trials and growth chamber studies. Populations when planted in strip mine soils in field trials and controlled growth experiments. Later flowering in strip mine populations may be a key to survival strategy in the harsh microclimates of …

Oysters from the James displayed variations in Kepone residue levels related to water temperature and their spawning cycle. Oyster depuralion rates were related to temperature. In summer the "biological half. life" of Kepone in oysters was about one week, while during the winter about 40 days were required for residue levels to decline by 50 per cent. Residues in blue crabs varied as a function of sex, males having considerably higher residues than females. Fin fish levels from the James varied greatly, with residue levels being dependent on species and length of residence for migratory fishes .. Average Kepone residues …
