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.

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 …

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 Effects Of Nest-Box Visibility And Proximity On The Frequency Of Brood Parasitism In Wood Ducks, Roger W. Jansen
The Effects Of Nest-Box Visibility And Proximity On The Frequency Of Brood Parasitism In Wood Ducks, Roger W. Jansen
Masters Theses
I studied the effects of nest box visibility and clustering on the rate of intraspecific brood parasitism (IBP) in Wood Ducks (Aix sponsa) at Lake Shelbyville Fish and Wildlife Area in Moultrie County, IL from 2 March 1992 to 22 June 1992. Sixty-eight percent of the nest boxes sampled were used and 33% of the nests were destroyed by predators. Mean clutch sizes of unparasitized (x = 9.2) and parasitized (x = 15.2) nests were significantly different. The parasitism rate in Wood Duck nests was 54%. More visible boxes had a tendency to be parasitized at a higher rate than …
Vegetation And Tree Survival In A Savanna Restoration Project, Vermilion County, Illinois, Mary Claire Hruska
Vegetation And Tree Survival In A Savanna Restoration Project, Vermilion County, Illinois, Mary Claire Hruska
Masters Theses
This study involved pre-burn and post-burn inventories of herbaceous and woody vegetation, a post-burn tree survival survey, the development and implementation of a management plan for the savanna restoration site and the development of general guidelines for savanna restoration. An herbarium collection was made, 242 species representing 64 families were found on the site.
There were several significant changes in the density and frequency of vegetation after the burn. The following herbaceous species increased significantly in frequency: Agalinis tenuifolia (Vahl.) Raf, Ambrosia artemisiifolia L., Carex spp., Cassia fasciculata Michx., Desmodium glabellum (Michx.) DC., Dichanthelium acuminatum (Sw.) Gould & Clark var. …
An Electromyographic Study Of Forward Vs Retrograde Stair Climbing On The Stairmaster 4000 Pt Machine, W. Lynette Rasmussen Thornburgh
An Electromyographic Study Of Forward Vs Retrograde Stair Climbing On The Stairmaster 4000 Pt Machine, W. Lynette Rasmussen Thornburgh
Masters Theses
The purpose of this study was to investigate, through electromyography, whether forward or retrograde stair climbing on the StairMaster 4000 PT machine demonstrates a greater muscle contraction duration, differences in intensity of muscle contractions, or variation in initiation of muscle contractions. The muscles examined were the Rectus Femoris, Vastus Medialis, and Biceps Femoris. A gender difference was also evaluated.
Twenty-one subjects apparently healthy volunteered for this study. There were two groups of ten male subjects and eleven female subjects. Subjects were assigned to subgroups according to gender. The subgroups determined which position the subject was tested in first.
The descriptive …
Biotic, Abiotic, And Behavioral Patterns Associated With The Nocturnal Movements Of Shrews, Patrick T. Sullivan
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.
Lichen Communities On White Oaks In East-Central Illinois, Michael R. Thon
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 …

Corticolous Bryophytes Of East-Central Illinois, R. Korkut Canayakin
Masters Theses
Among the numerous factors that influence epiphytic corticolous bryophytes, inclination, "raintracks", aspect, and phorophyte seem to play important role.
In order to determine the effects of these factors, 203 forest trees located in five sites has been examined. The results were arranged in tables and charted.
The Effects Of Turf Compression On Plants Growth Regulator Efficacy, William Lyle Petersen
The Effects Of Turf Compression On Plants Growth Regulator Efficacy, William Lyle Petersen
Masters Theses
A 150kg lawn roller was used in combination with various Plant Growth Regulators (PGR) (Embark & Event, Event & Oust, Embark & Oust, Escort & Oust, Telar & Oust, Event & Balan, Oust & Balan, and Balan) to evaluate its affects on the growth rate of rough turf at the Coles County Airport. The rolled plots were evaluated for height, reduction of seedheads, phytotoxicity, and weed control. Rolling was of no significance to treated or untreated turf. PGR combinations containing Oust were significantly better at reducing turf height than combinations lacking Oust. PGR combinations lacking Oust discolored turf significantly less …
