Some Factors Affecting Male Mating Success In The Giant Waterbug (Belostoma Flumineum Say), Karyn S. Crisman

Masters Theses

Giant waterbugs (Subfamily Belostomatinae) are interesting in that males provide exclusive post-copulatory care of young. This unusual behavior makes this species an excellent study system for investigations of sexual selection theory because in such systems, sex role reversals are predicted. Previous studies indicate that role reversal in giant waterbugs is not complete because males still court females. It is assumed that from this courtship display females can assess male quality and "choose" a superior male. If some males are chosen over others then differential mating success results. This study was undertaken to ascertain some of the factors that affect male …

Invertebrates Associated With The Pincushion Moss (Leucobryum Glaucum) And Underlying Soil, Timothy R. Leffler

Masters Theses

A faunal study of soil invertebrates collected from pincushion moss (Leucobryum glaucum) and underlying soil in a mixed deciduous forest of Charleston, Illinois, was performed because it was discovered that moss habitats have been largely overlooked by investigators.

The results from this study suggest that moss habitats provide a buffer area from the external physical environment, provide protection from predators, a place for oviposition and may be used as a food source. Twenty-seven orders of invertebrates were collected (66,023 individuals). Acarina (57.9%) and Collembola (37.9%) made up the majority of the invertebrate population. Three abiotic factors (temperature, moisture …

Callus Formation And Differentiation In Embryos Of The Coconut Palm (Cocos Nucifera L.), Jyoti Mangesh Desai

Masters Theses

Embryos of Cocos nucifera L. were allowed to develop on various agar based, plant tissue culture media. Environmental conditions, temperature, light intensity levels and photoperiod were regulated throughout the period of the experiment. The anatomy of commercially available embryos (excised from the "seed") and tissues that developed in culture (calli, roots and leaves) was determined. Prepared slides and tissues obtained in culture were photographed and printed. Callus, root and shoot formation were successful. However, "embryoids" which would have eventually led to free living plantlets were not obtained during this study. Successful regeneration of plantlets in culture would require improved techniques.

The Effects Of Aspartame On Locomotion And Body Weight In Rats, Linda Dianne Dykema Larsen

Masters Theses

Nutrients, when ingested in isolation from other food stuffs or in excess, may produce drug-like action on neurotransmitter activity in the CNS. Administration of aspartame exclusively or in combination with d-amphetamine was found to produce weight loss and display of emotionality in rats as measured in an open field apparatus. The possible neurochemical action of aspartame was discussed relative to the well documented stimulatory effects on catecholamines of d-amphetamine and three putative mechanisms were explored: 1) formation of minor amines from the increased precursor pool, 2) increased synthesis of catecholamines in response to the increased precursor pool, and 3) decrease …

Fecal Coliform Membrane Filtration Recovery Techniques, Pamela Rose Rinebold

Masters Theses

Researchers over the years have been trying to improve recovery techniques for fecal coliform bacteria. Improved techniques would provide better estimates of the number of fecal coliform bacteria as well as better estimates of fecal contamination with potential pathogenicity of food and water.

Stressed, but viable, fecal coliform bacteria if placed under the appropiate conditions, can recover, thus presenting the possibility of inadequate disinfection. Chlorine sanitization, as done in potable and wastewater treatment, is one such method of stressing bacteria.

Techniques of recovery were studied using presumably unstressed and chlorine stressed samples. Phase one of this study was the comparison …

The Application Of Multiderivative Infrared Spectroscopy To Iodine Number Determination, Jeffrey C. Lowry

Masters Theses

The Food and Drug Administration requires the disclosure of total unsaturation of commercial products as an indication of nutritional value. This unsaturation is a guide to the expected stability of food additives, such as edible oils and foods in which they are used. Unsaturation is typically evaluated as an iodine number, calculated for these additives based on their consumption of iodine through addition across the carbon-carbon double bonds. This titration method can typically take 45 minutes.

The investigation presented develops an alternative method for determining iodine numbers of some common oils using a computerized infrared spectophotometer. The analysis time, as …
