The Age And Fertility Of Lignite Strip Mine Spoils From The Darco Mine, Harrison County, Texas, Reagan Cook

Electronic Theses and Dissertations

Field observation of lignite strip mine spoils from the Darco mine near Marshall, Texas, revealed that gray spoil materials of various ages were devoid of vegetation. Within the same sites, spoil materials which were non-gray supported several conditions of revegetation. Analysis of spoil materials from this mine was undertaken to determine if spoils were differentiated on a chemical basis. Gray materials appear to have greater mineral sources of zinc, iron, and sulfate than non-gray spoils, and greater concentrations of zinc, calcium, magnesium, and potassium at all sites. Further, older spoils (17 to 31 years of age) have mean pH values …

Use Of Lignite Fly Ash As A Soil Amendment, Thomas Victor Brown

Electronic Theses and Dissertations

One-year-old loblolly pine (Pinus taeda L.) seedlings were grown in a greenhouse in potted mixtures of two Texas lignite fly ashes and a Troup sand, Sacul sandy loam, and a sandy clay loam strip-mine spoil. Mixtures contained 0, 25, 50, 75 and 100 percent fly ash. After six months, soil fly ash mixtures were analyzed for N, P, Ca, Mg, K, Na, Mn, Zn, pH, cation-exchange capacity, percent base saturation, and texture. Needle and root tissue analyses were performed on both live and dead seedlings. Survival and height growth were both adversely affected by fly ash amendments. Nearly all seedlings …

Why Does Spruce Not Invade The High Elevation Beech Forests Of The Great Smoky Mountains?, Robert Dale Fuller

Masters Theses

Above 1,370 m, spruce-fir forests dominated by Picea rubens Sargent and Abies fraseri (Pursh) Poiret from a nearly continuous band across much of the landscape of the Southern Appalachian Mountains. Nearly pure stands of American Beech (Fagus grandifolia Ehrhart) penetrate into the spruce-fir forest on south-facing concave slopes, near the tops of major ridges. Frequently the boundary between these two community types is very abrupt.

Important factors in the maintenance of these so-called "beech gaps" against red spruce invasion were investigated. Soil temperature, soil moisture, and the presence of biotic toxins were studied in the rooting environment of potentially …

Laboratory Comparisons Of Two Species Of Liquidambar, Lynn Wellman

Masters Theses & Specialist Projects

Laboratory germinated seedlings of Liquidambar styraciflua L., sweet gum, from Barren County, Kentucky, subjected to a flooding or inundation test were shown to respond in significantly different ways than did the controls. Plants with root systems standing in water showed a much shorter period of non-dormancy than plants that were not subjected to submergence when both were grown under long day, warm temperature conditions in growth chambers. There was no evidence of transfer of a growth retardant or dormin-like compound in water transferred from plants grown under short day (long night) conditions to plants with roots submerged under long day …

Leaf Litter Processing In Aquatic Systems Two Variable Model, Boyd Jay Hanson

Theses and Dissertations

The adequacy of the negative exponential model with one independent variable, days or accumulated time, as a descriptive equation for aquatic leaf litter processing was examined. The effect of adding a second independent variable, degree days or accumulated temperature, to the model was also examined. The two variable negative exponential model was shown to have at least two advantages over the single variable model. The two variable model adequately fits litter processing data for more cases than the single variable model. The expanded model also allows determination of rate coefficients for various temperature levels of the experiment rather than assuming …

Algal Response To A Thermal Effluent : Study Of A Power Station On The Provo River, Utah, Usa, Lorin E. Squires

Theses and Dissertations

The effect of a thermal effluent on the attached algae of the Provo River, Utah, USA, was studied from 1975 to 1977. Data for macroscopic and microscopic algae were collected and analyzed. Diatoms, Cladophora glomerata, and Hydrurus foetidus dominated the flora. The thermal effluent significantly affected the algal flora in a section of river 100 to 135 meters long immediately below the discharge point. Cladophora growth was increased and Hydrurus was absent in this area. In addition, diatom production was often higher and diversity lower than in the rest of the river. Community structure was unique from all other adjacent …

Photosynthetic Fractionation Of Oxygen Isotopes, A Study With Elodea Canadensis, Glen E. Martin

Theses and Dissertations

Bubbles of oxygen from Elodea canadensis were collected and found 5 per mil enriched in 0-18. This confirms the results of both Dole and Vinogradov, who found 0-18 enrichment of photosynthetic oxygen relative to its source, i.e. water. Photosynthesis and respiration appear to have produced the Dole effect, i.e. the 22 per mil 0-18 enrichment of atmospheric oxygen relative to ocean water, its probable source. These results are contrary to findings for both UV photolysis and electrolysis of water both evolving oxygen found depleted in 0-18.

Feeding Biology And Ecological Aspects Of A Cancroid Crab Cancer Oregonensis (Dana) Rathbun (Decapoda, Brachyura), Gary L. Child

Theses and Dissertations

In the San Juan Archipelago, cancer oregonensis (Dana) Rathbun (Fig. 1) is abundant and distributed from the low intertidal zone to -435 m subtidally (Rathbun, 1904). Ricketts and Calvin (1974) refer to c. oregonensis as the most common Cancer species in this area.

A Study Of Oyster Ground Leases Adjacent To The James River Bridge, Newport News, Virginia, Dexter S. Haven, Paul C. Kendall, William C. Phoel

Reports

This report describes a study by the Virginia Institute of Marine Science (VIMS) on portions of the river bottom adjacent to the former site of the original James River Bridge near the Isle of Wight end. Comparisons are made of the results obtained in thi.s study (done in July and August 1977) with r2sults from a study done (in April 1976) prior to the removal of the original bridge.

The purposes of the two studies were: 1) to assess the impact (if any) of the bridge-removal activities; and 2) to quantify the magnitude of oyster stocks and their economic value.

The Flora Of Citico Creek Wilderness Study Area, Cherokee National Forest, Monroe County, Tennessee, Jeffry Lowell Malter

Masters Theses

Citico Creek Wilderness Study Area, located entirely within the Cherokee National Forest, Monroe County, Tennessee, is under consideration for inclusion in the National Wilderness System. A study of the vascular flora of this 6,716 hectare area was conducted between March, 1976 and September, 1977. A total of 536 taxa, including 259 county records, was determined. This represents approximately 23% of the state flora.

Pertinent literature on the history, climate, geology, soils, and vegetation of the area is summarized. Particular note has been made of rare plants, with seven on the Tennessee list being found. One of these, Juncus gymnocarpus Coville, …

Discriminant Analysis Of Some East Tennessee Forest Herb Niches, Linda K. Mann

Masters Theses

The purpose of this study was to evaluate the effectiveness of using discriminant analysis in assessing plant niches. As a preliminary to establishment of the Environmental Research Park Program at Oak Ridge, Tennessee, five sites were inventoried for herbaceous species. From this inventory, four sympatric species of Galium and seventeen co-occurring herbaceous species were selected for discriminant analysis. The four species of Galium were treated as two data sets: one was composed of information collected at one site (a mesic hardwood area) and the other contained data from two cedar sites of shallow soil over lime-stone bedrock. The seventeen herbaceous …

Morphometric Variation In The Tropical Pocket Gopher (Geomys Tropicalis), Stephen L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The tropical pocket gopher (Geomys tropicalis). which exhibits no chromosomal or genic variation, was examined for variability at the morphometrical level. Univariate and multivariate analyses were used to determine age, sexual, and geographical variation. Significant differences were found between different age classes and between sexes. The amount of individual variation was comparable with other rodents and did not exhibit the reduced variation expressed at the chromosomal and genic levels, G. tropicalis is considered to be a monotypic species.
