Effects Of Acidic Precipitation On The Soil Chemistry And Bioavailability Of Aluminum, Manganese, And Copper, Alan Christie Stam Dec 1989

Effects Of Acidic Precipitation On The Soil Chemistry And Bioavailability Of Aluminum, Manganese, And Copper, Alan Christie Stam

Doctoral Dissertations

The effects of acidic precipitation on the soil solution chemistry and bioavailability of AI, Mn, and Cu in soils from spruce-fir and oak-hickory forests were examined in laboratory, greenhouse, and field studies.

Soil solution concentrations of labile (inorganic) monomeric AI (LMAI) increased with decreasing solution pH and with increasing exchangeable AI and decreasing exchangeable Ca/AI of the soils. Dissolved organic matter decreased with decreasing solution pH and influenced decreases in nonlabile (organic) monomeric AI (NLMAI).

Simulated acidic precipitation increased LMAI concentrations in the laboratory equilibration and greenhouse studies, but not in the field plot studies in oak-hickory and spruce-fir forests. …

The Genus Marasmius From The Southern Appalachian Mountains, Dennis Edmund Desjardin Aug 1989

The Genus Marasmius From The Southern Appalachian Mountains, Dennis Edmund Desjardin

Doctoral Dissertations

The genus Marasmius (Tricholomataceae, Agaricales, Basidiomycotina) constitutes one of the larger genera of litter-decomposing and litter-binding mushrooms, represented worldwide by approximately 500 species. Thirty-eight taxa representing eight sections of the genus are recognized as occurring in the southern Appalachian Mountains. Seven of these taxa are new to science, while an additional 14 are reported for the first time from the study area. In addition, one new section is proposed.

Descriptions of southern Appalachian species of Marasmius have been compiled from data on macro- and micromorphological features of basidiomata, supplemented with data on geographical and ecological distribution. Details on nomenclature and …

Life History And Ecology Of The Barrens Topminnow, Fundulus Julisia Williams And Etnier (Pisces, Fundulidae), Patrick L. Rakes May 1989

Life History And Ecology Of The Barrens Topminnow, Fundulus Julisia Williams And Etnier (Pisces, Fundulidae), Patrick L. Rakes

Masters Theses

The life history of the Barrens topminnow, Fundulus julisia, was investigated in a two-year study from 1983 to 1985. The species is restricted to a few isolated springs and groundwater-influenced upland streams on the Barrens Plateau in the vicinity of Manchester in middle Tennessee. In most aspects of its behavior, including feeding and reproduction, this topminnow differs little from other members of the same genus. The fish is an opportunistic carnivore, feeding upon aquatic insects, crustaceans, and gastropods, as well as terrestrial insects that fall in water. Like other killifish, F. julisia has an extended breeding season that is …


Does Rubus Canadensis Interfere With The Growth Of Fraser Fir Seedlings?, Eric Frank Pauley May 1989

Does Rubus Canadensis Interfere With The Growth Of Fraser Fir Seedlings?, Eric Frank Pauley

Masters Theses

Vegetation change in the Great Smoky Mountains following balsam woolly adelgid-caused mortality of Fraser fir has included development of a dense Rubus canadensis shrub layer. Many fir seedlings have persisted in the forest understory, but the possible effects of Rubus on their annul growth have not been intensively studied.

This study had two objectives: (1) to determine if significant associations exist among density and shoot growth of Fraser fir seedling, density/biomass of Rubus canadensis, canopy closure, and soil chemical parameters, and (2) to determine the effects of removal of aboveground Rubus stems on fir seedling shoot growth.

The Use Of Modified Atmoshere Packaging And Phosphate-Citric Acid Dip To Extend The Shelf Life Of Fresh Catfish, Ictalurus Punctatus, Brian Preston Moore May 1989

The Use Of Modified Atmoshere Packaging And Phosphate-Citric Acid Dip To Extend The Shelf Life Of Fresh Catfish, Ictalurus Punctatus, Brian Preston Moore

Masters Theses

Ninety market size catfish (Ictalurus punctatus) 1 - 2 pounds live weight were slaughtered, dipped in one of three solutions (phosphate, phosphate + citric acid, no dip) then packaged in one of three atmospheres (100% CO2, 70% CO2 + 5% O2 + 25% N, Air) and were stored at 1oC or 5oC. The catfish were evaluated for aerobic plate count, anaerobic plate count, lactic acid count, coliform count, pH, oxidation, drip loss, color and odor at 0, 4, 8, 12 and 16 days. The 100% CO2 and 70% CO2 atmospheres …


The Effect Of Heat Treatments On Dietary Fiber As Assessed By Chemical Analysis And Scanning Electron Microscopy, Ming-Cheng Chang May 1989

The Effect Of Heat Treatments On Dietary Fiber As Assessed By Chemical Analysis And Scanning Electron Microscopy, Ming-Cheng Chang

Masters Theses

Today it is generally accepted by many nutritionists that dietary fiber plays an important role in human health. Increased consumption of dietary fiber is advocated for beneficial effects on human health; thus food technologists and the food industry are interested in the use of fiber as an ingredient in food products and in the manufacture of high fiber foods. Numerous researchers have concentrated on the physiological effects of dietary fiber, while few have investigated the effect different processing parameters have on dietary fiber.

Apple fiber, corn fiber, oat bran and soy fiber were prepared and analyzed after further processing (autoclaving …


Physical And Sensory Properties Of High-Fiber, Reduced-Fat Biscuits, Pamela J. Stanyon May 1989

Physical And Sensory Properties Of High-Fiber, Reduced-Fat Biscuits, Pamela J. Stanyon

Masters Theses

Rolled biscuits were prepared with 0, 14, 28, and 42% wheat bran substituted for flour and 0, 20, 40, and 60% polydextrose substituted for hydrogenated shortening. Effects on physical and sensory characteristics of biscuits containing 16 combinations were determined with response surface methodology. Wheat bran decreased volume and produced harder, gummier, and chewier biscuits. Panelists indicated crumblier, drier, and chewier biscuits as bran level increased. Unlike wheat bran, polydextrose increased volume and decreased hardness. Panelists scored biscuits made with polydextrose as more moist, but no more chewy than biscuits made without polydextrose. Polydextrose appeared to impede some of the negative …
