The Effects Of Pre And Postnatal Gonadal Hormone Administration On The Adult Aggressive-Target Biting In Female Mice, David D. Smith

Masters Theses

Introduction

It is now well established that androgens and estrogens are intricately involved in influencing the sexual differentiation of the brain, as well as male and female differences of aggressiveness. Evidence is accumulating which indicates that these steroid hormones influence the pattern of nervous connection and organization developing in utero and in the early postnatal period.

To more completely link testosterone's involvement with aggressive behavior, one must examine the voluminous literature which links testosterone with developing neonatal correlates of aggression as well as with adult capacity to display aggressive behavior. In most species the male is more aggressive than the …

Translocation Of C14-Labeled Assimilates In Squash Petioles, William John Raupp

Masters Theses

A qualitative analysis of sieve tube sap was undertaken to help determine the method of assimilate movement in phloem. Hydroponically-grown squash plants (Cucurbita melopepo torticollis Bailey) were trimmed to a mature, fully-expanded leaf (the source) and one or more immature, unexpanded leaves (the sinks). The blade of the source leaf was exposed to C¹⁴O₂ in air for 10 minutes and allowed to translocate for 20 or 50 minutes in ambient air. Petioles of treated leaves were cut into sections and ground in cold buffer with a chilled mortar and pestle to extract materials from the translocation stream. …

Biosystematic Studies Of Impatiens Pallida And Impatiens Biflora (Balsaminaceae), Sandra M. Buening

Masters Theses

Impatiens pallida Nutt. and Impatiens biflora Walt. are two closely related species which grow together in mixed populations but do not hybridize. Flower buds of each species were enclosed with glycine bags to prevent insect pollination. These were left isolated until after anthesis to test for self-pollination and self-compatibility. Neither capsule formation nor seed set were observed.

Chromosomal smears showed that each species has a haploid number of ten chromosomes. Polyploidy was not observed.

Field observations of insect pollinators (primarily bees) showed indiscriminate visitation.

Flower buds were again bagged as before. During anthesis, individuals of the two species were cross-pollinated …

Masters Theses

Five hundred and twenty-two squirrels were trapped and retrapped from a population in Montgomery County, Maryland during 1974-1975. One hundred and forty-one squirrels were found to harbor an average of 10.6 mites (Range 175-1). While male squirrels outnumbered females (79 vs 62) females harbored more mites than males (829 vs 666). During the spring the average number of mites per captured squirrel increased to an average of 18.1 per squirrel. The average declined to 6.8, 4.8 and 3.3 per squirrel in summer, fall and winter respectively. Throughout the collection period adult female mites were by far more numerous on hosts …

Studies Of The Lysogenic Response As A Function Of Multiplicity Of Infection Of Lambdoid Bacteriophages, Mark Floyd Fedyk

Masters Theses

The lambdoid bacteriophages λimm^λ, λimm⁴³⁴ and λcI are ideal subjects for the study of gene product interactions at the molecular level due to their closely related genetic makeup. Previous work in this laboratory has indicated the possibility that phage λimm is sensitive to phage λimm⁴³⁴cI gene product and that phage λimm⁴³⁴ is sensitive to phage λimm^λcI gene product. The purpose of this research was to determine if the frequency of lysogeny for phage λimm^λ is affected by the multiplicity of coinfection with the λimm⁴³⁴ phage. By comparing the graph of …

Histology Of Dichromatic And Seasonal Color Change Of The Cranial Region Of Callagur Borneoensis, Kevin William Matson

Masters Theses

Male Callagur borneoensis exihibit sexual dichromatism and seasonal coloration which is rare among turtles. In the breeding season male's heads are colored white with a scarlet stripe from the occiput to the tip of the snout. After the breeding season they change to drab charcoal-gray to black with a dull orange-yellow stripe. Females and juveniles are a drab brown throughout the year.

This study was performed to determine the mechanisms of this color change at the histological level. Histological preparation of the head revealed a significant increase in vascular tissue just below the epidermis of the stripe area with increased …

Three and two tenths percent (4) of the birds sampled were infected with Eimeria of apparently four different species. These species were tentatively designated as: E. meleagridis, E. adendeides, E. meleagrimitis and E. subrotunda.

A Population Study Of The Cave Beetle Neaphaenops Tellkampfi (Coleoptera, Carabidae) In Mushroom Cave, Hart County, Kentucky, Robert E. Bon Durant Sr.

Masters Theses

A two year census of the cave beetle Neaphaenops tellkampfi (Coleoptera, Carabidae) was conducted in Mushroom Cave, Hart County, Kentucky. Three methods were used to estimate populations of this beetle. A rise in population in certain areas of the cave was shown to occur in Mid-winter. The population as reported is felt to represent a portion of a much larger population which migrates toward the cave entrance beacuse of food shortages in winter with a summer movement back into deep cave habitat when the eggs of Hadenoecus subterraneus are plentiful.

The Biodegradation Of Crude Oil By Bacteria Isolated From Brine Pits, Larry Williams

Masters Theses

The biodegradation of crude oil by bacteria was studied. Hydrocarbon-utilizing bacteria were isolated from sixteen brine pits from an oil producing region of Clark County, Illinois. The bacteria were capable of growth from the vapors arising from crude oil as a sole carbon source. Some strains of bacteria were capable of emulsifying crude oil, apparently through the production of an emulsifying agent(s) that was found to be heat stable and cell bound but which can be partially stripped from the cell by autoclaving. The bacteria appear to belong to the genus Arthrobacter. The chemical environment of the pits was …
