A Biotic Analysis Of The Dobbs Park Natural Area With Emphasis On Spatial Distribution Of Trees In The Old-Growth Forest Section, Ronald L. Helms
All-Inclusive List of Electronic Theses and Dissertations
Dobbs Park is a 105-acre tract, located at the east edge of Terre Haute, Indiana. Community types range from grass-forb to a 14-acre mature deciduous forest. The tract was divided into 36 units from which 14 community types were developed. The large number of community types appears to be a product of discontinued tillage or grazing within various sections of the tract at different times. The mature forest is largely upland depressional, much of which is subject to periodic pending. Dominants among the 34 tree species present are elms (Ulmus americana, rubra and thomasii) and ashes (Fraxinus americana and pennsylvanica) …

Heating-Effect Minimization In Dye Lasers, Kenneth Lee Matheson, James M. Thorne
Heating-Effect Minimization In Dye Lasers, Kenneth Lee Matheson, James M. Thorne
Faculty Publications
Optical pumping of dye lasers deposits heat nonuniformly in the active medium. Because the refractive index of a liquid or gas is a function of temperature, gradients are created which refract the laser beam. This effect is sometimes serious enough to quench laser action. In this paper, we evaluate the effects caused by optical pumping with a coaxial flashlamp and suggest ultraviolet absorbers and wavelength shifters as materials for minimizing the problem

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 …

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.

The Reproductive Biology Of The Diamondback Terrapin, Malaclemys Terrapin Tequesta, Richard A. Seigel
Retrospective Theses and Dissertations
The reproductive biology of the Florida east coast terrapin, Malalemys terrapin tequesta was studied during 1977-1978 at the Merritt Island National Wildlife Refuge, Brevard County, Florida. Mating occurred in small canals and ditches during late march and April. Terrapins exhibited a poorly developed courtship behavior system: this was attributed to the relative isolation of the species due to its brackish water habitat. Nesting occurred on dike roads, rather than on sand dunes as reported for other races of Malaclemys. Air temperature was the most important factor controlling nesting activity. One to three clutches were laid each year. Malaclemys appeared to …

Feeding Morphologies And Distribution Patterns Of Marine Cladocera In The Lower Chesapeake Bay, Sandra Layne Gilchrist
Feeding Morphologies And Distribution Patterns Of Marine Cladocera In The Lower Chesapeake Bay, Sandra Layne Gilchrist
OES Theses and Dissertations
Temporal and spatial distributions of marine cladocera in the lower Chesapeake Bay estuary were observed over a year-long sampling period. The distributions of cladoceran species throughout the Bay were studied in relation to temperature and salinity. A survey of the species over the entire Bay is included to establish distribution patterns of the various species during a short time period.
Theoretical mathematical principles were used to predict feeding abilities of the Bay species. Mouthparts are described qualitatively and quantitatively to infer function. A mandibular index developed by Itoh (1970) was revised and employed in evaluating feeding methods interspecifically and interspecifically. …

The Spatial And Temporal Distribution Of Fish Eggs And Larvae In Hempstead Bay Estuary, Joseph Adelard Lessard
OES Theses and Dissertations
The ichthyoplankton of Hempstead Bay estuary was sampled from December 1972 to mid March 1974. Eleven stations were sampled by towing a 0.5 meter diameter plankton net. Eggs were most abundant during June and July with an average concentration calculated to be above 5,500/100m3. Egg densities were the lowest during the fall and winter. Larvae were most frequently taken from March through July with densities varying greatly among the samples. The eggs of Brevoortia tyrannus, Anchoa mitchilli, Tautoga onitis, Tautogolabrus adspersus, and Scophthalmus aguosus and the larvae of Menidia menidia, Ammodvtes hexapterus and Pseudopleuronectes americanus constituted most …

A Study Of Fiber Orientation In Machine Made Papers, Phillip W. Forsyth
A Study Of Fiber Orientation In Machine Made Papers, Phillip W. Forsyth
Paper Engineering Senior Theses
The purpose of this thesis was to study fiber orientation in paper made on the pilot plant paper machine at Western Michigan University. The variables used in the study were fiber length and draw tensions. The shrinkage of the web was one dependent variable that was measured.
It was found that, on this paper machine, fiber orientation is independent of fiber length. Also, large draw tensions will increase the degree of orientation in the direction of the draw. And finally, increased draw tensions will result in an increase of MD elongation and CD shrinkage.
It is recommended here that further …

Evaluation Of A Simplified Measurement For Low Glomerular Filtration Rates With Lndium-111 Dtpa, L. E. Preuss, R. S. Michaels, F. P. Bolin, N. W. Levin, C. Artman
Henry Ford Hospital Medical Journal
A rapid new method for measuring glomerular filtration rates using 111In diethylenetriamine pentaacetic acid (111In- DTPA) was evaluated with 39 patients who showed marked impairment of renal function (creatinine clearance less than 20 ml/min). A simple, single compartment system was assumed. For comparison, parallel inulin and creatinine clearances were performed. High linear correlations (r = 0.96-0.97) were demonstrated when 111In- DTPA clearances were compared with the standard nonisotopic tests. Initial data indicate that reliable isotopic clearance values could be obtained for low clearances by withdrawing only two blood samples for assay at 6 and 48 hours after isotope injection (without …

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 …

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 …
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 …

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 …
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 …
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 …
