Demography And Genetic Structure Of An Allegheny Woodrat Population In Northcentral West Virginia, Mary Elizabeth Manjerovic
Demography And Genetic Structure Of An Allegheny Woodrat Population In Northcentral West Virginia, Mary Elizabeth Manjerovic
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Allegheny woodrat (Neotoma magister) occurs throughout the Appalachian Mountains forming isolated colonies in rock outcrops, cliffs, and caves. In the past 20--30 years, populations along the northern and western peripheries of the range have experienced drastic declines. There have been suggested reasons for this decline but a lack of long-term data has prevented application of specific management actions. In recent years, there has been more insight into population structure, gene flow, and relatedness among colonies. The objectives of my study were to examine these factors at a localized level to further assist with future management decisions.;Using data collected over …

Saprophagous Caterpillars (Lepidoptera: Noctuidae: Herminiinae): Effect Of Bacillus Thuringiensis Var. Kurstaki Application In Forest And Laboratory Settings., Karen Jeanine Kish
Graduate Theses, Dissertations, and Problem Reports (ETD)
The larvae of the Herminiinae are macrodecomposers of forest leaf litter. Eight species were studied to determine the effects of aerially applied Btk. Adults were collected weekly by light trap for 7 consecutive seasons. The first 2 years provided baseline information, followed by 2 years of Btk treatment and 3 post-treatment years. Idia aemula (Hübner)(Lepidoptera: Noctuidae) larvae were collected from control plots and treated with Btk in the laboratory to determine susceptibility. Untreated larvae were reared to adulthood and mated to obtain information on their biology. Differences in light trap counts between years were significant for all 8 species. Forest …
Ecology And Management Of Raccoons Within An Intensively Managed Forest In The Central Appalachians, Sheldon F. Owen
Ecology And Management Of Raccoons Within An Intensively Managed Forest In The Central Appalachians, Sheldon F. Owen
Graduate Theses, Dissertations, and Problem Reports (ETD)
The raccoon (Procyon lotor), a generalist meso-predator, is commonly found throughout the eastern United States. Many researchers have examined the ecology and spatial requirements of raccoons in agricultural and wetland areas of the mid-western and southeastern United States. However, no studies have quantitatively examined raccoon habits in the forested central Appalachians and their response to forest management. During the fall of 2000 through the spring of 2003, I monitored the spatial movements and den site selection of raccoons within an intensively managed forest.;I investigated the occurrence of raccoon roundworm (Baylisascaris procyonis) in raccoons (Procyon lotor) within my study area. I …
Censusing And Modeling The Dynamics Of A Population Of Eastern Hemlock (Tsuga Canadensis L.) Using Remote Sensing, W. Robert Lamar
Censusing And Modeling The Dynamics Of A Population Of Eastern Hemlock (Tsuga Canadensis L.) Using Remote Sensing, W. Robert Lamar
Graduate Theses, Dissertations, and Problem Reports (ETD)
A population of eastern hemlock (Tsuga canadensis L.) was censused from the ground using traditional field methods and from the air using large scale, high-resolution, aerial imagery in the early spring of 1997, 1998 and 1999. A manual crown survey map of the population, prepared from aerial imagery, was compared to a traditional field census. Over 60% of the individuals measured on the ground were not detected in the aerial census. Tree size, crown density and crown position all played roles in determining a crown's visibility from the air. Nearly all large, upper canopy hemlocks were visible in the aerial …
Second Natures: Media, Masculinity And The Natural World In Twentieth-Century American Literature And Film., Jeanne E. Hamming
Second Natures: Media, Masculinity And The Natural World In Twentieth-Century American Literature And Film., Jeanne E. Hamming
Graduate Theses, Dissertations, and Problem Reports (ETD)
This multidisciplinary dissertation examines the cultural anxieties associated with masculine identity in relation to both technology and nature in key literary texts and contemporary films of the twentieth-century: Ray Bradbury's “The Veldt†and The Martian Chronicles, Philip K. Dick's Do Androids Dream of Electric Sheep?, James Dickey's Deliverance , Don DeLillo's White Noise, Fight Club, American Psycho, Brazil, 12 Monkeys, and Dark City. Exploring the theoretical intersections of technoculture, ecocriticism, and gender studies, this dissertation analyzes the relationship between masculine identity and nature, as it is mediated by American technoculture. This relationship is marked by a discernible cultural malaise—a sense …
Fictions Of Nature: Ecology, Science, And Culture In Twentieth-Century British Literature., Neal Bukeavich
Fictions Of Nature: Ecology, Science, And Culture In Twentieth-Century British Literature., Neal Bukeavich
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation examines twentieth-century British fiction concerned with humankind's interactions with the nonhuman world. I analyze a range of literary works, including H. G. Wells's The Food of the Gods (1903), D. H. Lawrence's The Rainbow (1915), Women in Love (1920), and Lady Chatterley's Lover (1928), John Brunner's Stand on Zanzibar (1968), Graham Swift's Waterland (1983), and J. G. Ballard's Rushing to Paradise (1994). This body of literature remains largely unexamined for its treatments of ecological issues and belongs to a national history deeply implicated in local and global environmental change. Moreover, my consideration of this literary tradition marks a …
Microbial Ecology Of Freshly Sawn Yellow-Poplar Lumber ( Liriodendron Tulipifera L.) In Two Seasons, Mark Ryan Mikluscak
Microbial Ecology Of Freshly Sawn Yellow-Poplar Lumber ( Liriodendron Tulipifera L.) In Two Seasons, Mark Ryan Mikluscak
Graduate Theses, Dissertations, and Problem Reports (ETD)
Each year, the forest products industry sustains considerable product loss due to a reduction in market value of lumber brought about by microbial discoloration. The current practice of treating green lumber with chemical biocides to protect it from discoloration, although successful, is a potential hazard to both the environment and human life. One potential alternative to chemical biocides is biological control. The most recent success in the field of biological control has been achieved in the agricultural industry by first studying the microbial ecology of the substrate in which the biologically based preservative is to be used. Literature on microbial …

The Influence Of Soil And Soil Surface Characteristics On Habitat Selection By Carabidae. Part Ii. Precipitation And Temperature Fluctuations: Effects On Carabidae Activity. Part Iii. The Effects Of Two Microbial Insecticides For Gypsy Moth Control On Carabidae Populations., Terry R. Carrington
Graduate Theses, Dissertations, and Problem Reports (ETD)
A study was conducted in the George Washington National Forest in Virginia and the Monongahela National Forest in West Virginia. Carabid samples were collected over four years and compared to soil characteristics, surface characteristics and meteorological conditions to determine what role these factors play in carabid habitat selection. Opportunity also existed to compare carabid populations before and after the application of microbial insecticides on the sampling sites. This study was conducted as as part of a larger project investigating non-target impacts from gypsy moth, Lymantria dispar (L.)(Lepidoptera: Lymantriidae), insecticide applications and the interaction of Entomophaga maimaiga Humber, Shimazu, and Soper …
Testing The River Continuum Concept: Exploring Ecological Processes In The Wheeling Creek Watershed., Deborah Ann Carpenter
Testing The River Continuum Concept: Exploring Ecological Processes In The Wheeling Creek Watershed., Deborah Ann Carpenter
Graduate Theses, Dissertations, and Problem Reports (ETD)
The river continuum concept (RCC) asserts that the biological community in a stream system is largely regulated by geomorphological factors (Vannote, et al., 1980, 131). The concept states that community structure in natural stream systems is structured in order to capitalize on the most efficient energy utilization throughout. The objective of this research is to test the RCC in the Wheeling Creek watershed of northern West Virginia and southwestern Pennsylvania and to compare the results with those hypothesized under the RCC. One of the strongest criticisms of the RCC is that the continuum assumes an undisturbed stream system. Anomalies found …
Scale, Ecological Fallacy, And The River Continuum Concept, Hope M. Childers
Scale, Ecological Fallacy, And The River Continuum Concept, Hope M. Childers
Graduate Theses, Dissertations, and Problem Reports (ETD)
Concern over scale is not new, and it is not restricted to geographers. Spatial and temporal scaling is a conceptual and methodological problem for all sciences using geographic information. This paper teases out issues of scale and ecological fallacy from the literature and discusses how these issues influence the applicability of an influential theoretical framework in stream ecology, the River Continuum Concept (RCC). Investigators are faced with decisions regarding scale during sampling location selection, field data capture, and subsequent data interpretation. A thorough understanding of the heterogeneity of stream habitats and the life histories of the organisms being studied could …
Food Habits Of The Allegheny Woodrat (Neotoma Magister ), Nikole Lee Castleberry
Food Habits Of The Allegheny Woodrat (Neotoma Magister ), Nikole Lee Castleberry
Graduate Theses, Dissertations, and Problem Reports (ETD)
Regional declines in Allegheny woodrat (Neotoma magister ) populations suggest a better understanding of the ecology of this species is needed for proper management. I described seasonal food habits of the Allegheny woodrat in the Ridge and Valley and Allegheny Plateau physiographic provinces of West Virginia and Virginia using microhistological techniques. In the Allegheny Plateau, the top 5 food items were fungi, blueberries ( Vaccinium spp.), acorns (Quercus spp.), ferns ( Dryopteris spp.), and lichens. In the Ridge and Valley woodrats ate primarily blackberry (Rubus spp.) leaves, fungi, greenbrier (Smilax spp.) leaves, acorns, and oak leaves. Additionally, we examined the …
'Regional' Political Ecology And Underdevelopment In Appalachia: Case Studies From Two West Virginia Counties., James Todd Nesbitt
'Regional' Political Ecology And Underdevelopment In Appalachia: Case Studies From Two West Virginia Counties., James Todd Nesbitt
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation analyzes the environmental history of Pendleton and Randolph Counties, West Virginia, as it relates to underdevelopment within the broader Appalachian region. Theories of political ecology and reconstructed regional geography are used to gain a better understanding of the intersection between cultural practice and human use of the natural environment. Specifically, three case study locales are utilized in this study to demonstrate local variability in natural resource issues within the Appalachian region. Political ecology and reconstructed regional geography are integrated to create a conceptually and contextually refined 'regional' political ecology which accounts for issues of geographic scale and alternative …

Its most distinguishing features are: (1) its large o v al-sh ap e, 14 miles long and from two to four miles wide; (2) the presence of a relict Pleistocene flora and boreal communities; and (3) a wetland area of approximately 6,000 acres at a mean elevation of 3,200 feet. The vegetation of Canaan Valley was studied in respect to its flo ristic composition and its ecological im plications. …
A Taxonomic Study Of The Ericaceae Of The Southern Appalachian Highlands., Doyle Stewart Blauch
A Taxonomic Study Of The Ericaceae Of The Southern Appalachian Highlands., Doyle Stewart Blauch
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Southern Appalachian Highlands represent a unique geographical region in which to study plants. The Ericaceae, especially well developed in this region, are a family of plants which have long been of interest to man. At the present time there exists no adequate treatment of the Ericaceae of this particular area. The present study, based mainly upon examination of herbarium specimens and supplemented by studies in the field, attempts to correlate these findings with all the scattered published information concerning the genera of this family in the Southern Appalachians. More than 12,000 sheets of specimens from twenty-nine herbaria were examined …
