Fabrication And Characterization Of Thin, Self‐Supporting Germanium Single Crystals, M. W. Grant, P. F. Lyman, J. H. Hoogenraad, Barbara S. Carlsward, D. A. Arms, L. E. Seiberling, F. Namavar

Barbara S. Carlsward

Thin Gesingle crystals (≤1 μm) up to 4 mm in diameter have been fabricated from epitaxialGefilmsgrown by atmospheric pressurechemical vapor deposition on Si(100) wafers. The thin Ge windows are formed by chemically etching away both the Si substrate and the region of the Gefilm near the interface that contains misfit dislocations associated with heteroepitaxialgrowth and relaxation of the Gefilms. The resulting Gefilms are comparable in crystalline quality to bulk Ge wafers, as indicated by ion channeling studies.

Evolution Of Mammalian Social Structure, Ronald K. Chesser, Derrick W. Sugg, O. Eugene Rhodes Jr., James M. Novak, Michael H. Smith

Faculty Research & Creative Activity

Social groups may be viewed as collections of individuals exhibiting nonindependent behavior and organized in a cooperative manner. The evolutionary advantage of social behavior to individuals must be measured in its relativity to other potential behaviors, the scale of competitive interactions, and under a variety of environmental and genetic constraints. A primary tenet of social evolution is that coancestry will promote the genes of related individuals. High values of coancestry, however, do not necessarily translate into evolutionary advantage unless the primary competitive interactions occur among the groups. Coancestry is affected by the breeding tactics within and rates of genetic exchange …

Morphological Asymmetry In Mammals: Genetics And Homeostasis Reconsidered, James M. Novak, Olin E. Rhodes Jr., Michael H. Smith, Ronald K. Chesser

Faculty Research & Creative Activity

It has been hypothesized that developmental stability is increased at higher levels of genetic variability (heterozygosity) in animals. However, the existence of this relationship is questionable for homeotherms in general and mammals in particular. The difference between the sides of a bilateral character in an individual is a measure of fluctuating asymmetry that can be used as a measure of the developmental stability of mammals. Increased developmental stability should result in a greater degree of similarity between the right and left side of the body even though environmental variability would tend to increase the differences between right and left sides …

A Comparison Of Staining Techniques For Somatic Chromosomes Of Strawberry, Henry R. Owen, A. Raymond Miller

Faculty Research & Creative Activity

A factorial combination of pretreatments, fixatives, and stains was examined to identify the best available method for staining the chromosomes of strawberry (Fragaria × ananassa Duch. ‘Chandler’) root-tip cells. Three pretreatments ( a -bromonaphthalene, p -dichlorobenzene, and 8-hydroxyquinoline), three fixatives (Farmer’s fluid, Carnoy’s fluid, and Newcomer’s fluid), and five stains (acetocarmine, alcoholic hydrochloric-acid carmine, altered carbol fuchsin, lacto-propionic orcein, and leucobasic fuchsin) were tested. Pretreatment with either a -bromonaphthalene (saturated aqueous) or 8-hydroxyquinoline (2 mM) for 5 hours at 14C, overnight fixation in Farmer’s fluid, hydrolysis in 1 N HCl (15 minutes at 60C), and staining with altered carbol fuchsin …

The Oxyporinae (Coleoptera: Staphylinidae) Of Illinois, Rodney S. Hanley

Masters Theses

The monogeneric subfamily Oxyporinae (Coleoptera: Staphylinidae) is composed of the genus Oxyporus Fabricius. Members of the genus are obligate inhabitants of higher, fleshy mushrooms. The Illinois fauna of Oxyporus includes nine species from two subgenera which are treated in this study. A key to the identification of adults, descriptions, fungal host lists, and distributional maps are provided for each species. The most commonly collected species in Illinois are O. occipitalis, O. stygicus, O. major, and O. vittatus; uncommon or rare species are O. lateralis, O. quinquemaculatus (a new record for Illinois), O. femoralis femoralis, …

An Investigation Of The Host Specificity Of The Brown-Headed Cowbird, Brian D. Peer

Masters Theses

We attempted to determine the factors associated with the lack of parasitism of the Common Grackle (Quiscalus quiscula) by the Brown-headed Cowbird (Molothrus ater). We investigated the breeding phenology of the two species, the responses of colonial- and noncolonial-nesting grackles to female cowbird models, the frequency of artificial egg rejection by grackles, incubation success of cowbird eggs transferred into grackle nests, and the survival rates of cowbirds cross-fostered into grackle nests.

By the time cowbirds began egg-laying at our study sites, 88.5 % of all grackle nests were beyond the point of successful parasitism. Grackles responded …

Lichen Communities On White Oaks In East-Central Illinois, Michael R. Thon

Masters Theses

This study was conducted as a survey of epiphytic lichen communities occurring on white oak trees at Walnut Point State Park (Douglas Co.) and Fox Ridge State Park (Coles Co.). Using a system of cover classes to estimate lichen cover, quantitative data on the distribution and abundance of epiphytic lichens was obtained. These data were used to calculate summary statistics of each community including total cover, species richness, and Shannon diversity. A total of ten taxa representing six genera were found. The foliose lichen Physcia millegrana had the highest cover in the open canopy habitats while all other taxa had …

Biotic, Abiotic, And Behavioral Patterns Associated With The Nocturnal Movements Of Shrews, Patrick T. Sullivan

Masters Theses

Thirteen trails left by shrews coated with fluorescent powder were examined for microhabitat documentation. Thirteen data parameters were collected from each trail, two of which differed significantly between Blarina brevicauda and Sorex longirostris. The small soricid Sorex longirostris was captured in areas with higher grass content, and lower wooded content, than the larger Blarina brevicauda. The difference in microhabitat use may be a key mechanism in reducing competition between these two species.

Effects Of Music And Sensory Deprivation On Ratings Of Perceived Exertion And Exercise Affect, James Chinery

Masters Theses

Music as an ergogenic aid is a novel concept, and one that has been sporadically researched. The purpose of this thesis was to study the effects of music and sensory deprivation on ratings of perceived exertion during exercise.

Eleven active males (i.e. they exercised at least 3 times a week), were tested in three different conditions (music, sensory deprivation, control). They exercised in each condition, at workloads corresponding to 50, 70 and 90% of their maximal oxygen consumption. The sessions and workloads within each session were randomized.

No significant differences were found for heart rate between conditions. Significantly lower perceived …

The Effect Of Age On Recovery Of Heart Rate After Exercise, Shari A. Delisle

Masters Theses

The purpose of this study was to determine if heart rate recovery, following exercise, of active women aged between 50-63 years was significantly slower than the recovery of active women aged 23-24 years when both groups exercised at the same relative perceived intensity. Ten female subjects, five young and five older, were tested during a five minute bout of treadmill exercise while working at a rating of perceived exertion(RPE) of 14. Heart rate was measured prior to and during testing and into recovery using the Vantage Performance Monitor. The time, measured in seconds, it took for each subject to drop …

Phylogenetic Relationships Within The Batagur Complex (Testudines: Emydidae: Batagurinae), Jean M. Capler

Masters Theses

Relationships between 10 species of the batagurine genera Batagur, Callagur, Kachuga, Hardella, and Morenia are discussed based on a cladistic analysis of 35 morphological characters. Ocadia sinensis (Emydidae: Batagurinae) was used as the outgroup species. Four cladograms were produced with a length of 59.0 steps and a 0.75 consistency index. In contrast with previous studies, Hardella and Morenia do not appear as a monophyletic clade. Instead, Hardella is included with the remaining ingroup taxa (exclusive of Morenia) based on five synapomorphies. The present genus Kachuga was determined to be paraphyletic, having excluded the present genera Batagur and Callagur. The pangshura …
