The Savannah River Site: Site Description, Land Use And Management History, David L. White, Karen F. Gaines

Publications

The 78,000-ha Savannah River Site, which is located in the upper Coastal Plain of South Carolina along the Savannah River, was established as a nuclear production facility in 1951 by the Atomic Energy Commission. The site’s physical and vegetative characteristics, land use history, and the impacts of management and operations are described. Aboriginal and early European settlement was primarily along streams, where much of the farming and timber cutting have occurred. Woodland grazing occurred in the uplands and lowlands. Land use intensity increased after the Civil War and peaked in the 1920s. Impacts from production of cotton and corn, naval …

A Spatial Inquiry Of Infant Low Birthweight And Cancer Mortality In East Baton Rouge Parish, Louisiana, Esra Qzdenerol

LSU Historical Dissertations and Theses

Infant low birthweight rate in East Baton Rouge Parish is higher compared to the nation. Cancer is one of the most serious health problems in Louisiana. A few studies have indicated a relationship between the two health outcomes and their environment, but conclusions from these studies have not always been consistent. The spatial and temporal scales of the data and the methods used in these studies contribute to the inconsistent and uncertain results. The spatial patterns of infant low birthweight and cancer mortality in East Baton Rouge Parish from 1993 to 1996 and their relationships with environmental factors at three …

Microbial Biofilms: From Ecology To Molecular Genetics, Mary Ellen Davey, George A. O'Toole

Dartmouth Scholarship

Biofilms are complex communities of microorganisms attached to surfaces or associated with interfaces. Despite the focus of modern microbiology research on pure culture, planktonic (free-swimming) bacteria, it is now widely recognized that most bacteria found in natural, clinical, and industrial settings persist in association with surfaces. Furthermore, these microbial communities are often composed of multiple species that interact with each other and their environment. The determination of biofilm architecture, particularly the spatial arrangement of microcolonies (clusters of cells) relative to one another, has profound implications for the function of these complex communities. Numerous new experimental approaches and methodologies have been …

Palaeoecological Implications Of Archaeological Seal Bone Assemblages: Case Studies From Labrador And Baffin Island, James M. Woollett, Anne S. Henshaw, Cameron P. Wake

Earth Sciences

. In recent years, increasing scientific attention has been paid to sea mammals as biological indicators of Arctic environmental change. The usefulness of animals such as ringed seal (Phoca hispida), harp seal (Phoca groenlandica), bearded seal (Erignathus barbatus), and harbour seal (Phoca vitulina) as indicator species is due to the close relationship of their range, reproductive cycles, and life histories to sea ice. The behaviour and distribution of these species correlate with ice conditions in the areas where the animals are encountered. The proportions of seal species represented in archaeological deposits may therefore reflect, at least in part, environmental conditions …

Aspects Of The Winter Behavioral Ecology Of Anolis Carolinensis At The Northern Limit Of Its Range, David Christopher Bishop

Masters Theses

In the population used for this study, A carolinensis shift habitats prior to the winter season to a south-facing rocky bluff where they seek refuge in crevices at night and during cloudy days (Gatten et al 1988,personal observations). In part II of this Thesis, I describe the thermal properties of the crevices and the behavior of the lizards in relationship to the crevices. Body Temperatures of lizards were recorded prior to emergence from the crevices to determine if there were temperature differences between lizards with different masses and to see if lizards could maintain body temperatures independent of crevice temperatures. …

Univercity News (2000-11-06)

UniverCity News, 1998-2001

VCU Today, the University’s first official administrative organ, began as a somewhat irregular monthly publication but moved to a bi-weekly newspaper format in the 1980s. The newspaper changed its name to VCU Voice in 1988 and ten years later it appeared under the title UniverCity News. As it neared the end of its run as a physical newspaper, the publication became simply VCU News. These four publications were essentially the same periodical published under different titles by the Office of University Relations. VCU News appeared online for the first time in 2002.

University of Nebraska State Museum: Mammalogy Papers

On 11 June 2000, Dr. Elmer C. Birney unexpectedly passed away from cardiac arrest suffered while outside caring for his cattle at his home in Blaine, Minnesota. One of his former students, Robert Timm, probably best expressed the immediate reaction of his family and many friends: ‘‘He was too young and in too good of health to be gone so soon.’’ At the time of his death, Elmer was Professor in the Department of Ecology, Evolution and Behavior, the Curator of Mammals at the Bell Museum of Natural History, and Director of Graduate Studies of the program in Ecology, Evolution …

The Breeding Ecology Of White-Faced Ibis In The Lower Carson River Basin, Nevada, Eric Patrick Kelchlin

LSU Historical Dissertations and Theses

The Great Basin White-faced Ibis (Plegadis chihi) population is recognized as a Species of Management because of its small population size, limited number of traditional breeding sites, and vulnerability to habitat loss. The ability to predict future population trends and develop wetland management strategies is limited because many aspects of their breeding ecology and population dynamics are unknown. 1 examined White-faced Ibis nesting ecology and breeding habitat selection at the Lower Carson River Basin, Nevada, from 1995-1997, and the relationship between the local surface water conditions and trends in the number of breeding pairs from 1970-1997 on a local and …

The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter

Wildlife Damage Management Conference

Airports attract large numbers of wildlife primarily because they offer immense tracts of foraging and nesting habitats free from the threat of predation. Border collies can serve as an effective means of wildlife control in these environments by introducing a predator into the ecosystem. Many wildlife dispersal methods seek to imitate predators or the effect of predators and become increasingly ineffective as wildlife habituate to the stimuli. However, border collies are true predators, representing an actual, not perceived, threat to wildlife thereby eliminating the problems of habituation. Six airports and military bases have initiated use of border collies at their …

Wildlife Damage In The Suburbs: Conflicts In A Human-Wildlife Landscape, Rebecca Field

Wildlife Damage Management Conference Proceedings

The sprawling communities surrounding cities pose a paradox for wildlife. Suburban habitat, with parks, greenways, and planned open spaces, provide attractive habitat with abundant resources for some wildlife species. Yet the landscape is dominated by human activities and disturbances. Species with little tolerance for human disturbance and habitat changes have difficulty maintaining their populations in suburban environments. Yet more adaptable species flourish in suburban areas where there are less predators, increased food resources, and abundant habitat for cover and raising young. The resulting overabundant wildlife populations pose increasing problems for biologists, wildlife damage practitioners, and the public. Management of urban …

Management Guidelines For Sage Grouse And Sagebrush Ecosystems In Nevada, Bureau Of Land Management

All U.S. Government Documents (Utah Regional Depository)

These management guidelines and supportive background information promote the conservation of sage grouse (Centrocercus urophasianus) and their sagebrush (Artemisia spp) habitats on Nevada public lands administered by Bureau of Land Management (BLM). The guidelines are intended to provide interim guidance to field managers, without restricting options currently being explored for regional, state, and local sage grouse/sagebrush conservation planning. The guidelines are a Nevada BLM, habitat-specific, adaptation of the recently updated, and soon to be finalized, Western Association of Wildlife Agencies (WAFWA) Draft Guidelines. The Nevada BLM guidelines apply the most current sage grouse science to BLM activities, within the context …

Occurrence And Distribution Of Diverse Populations Of Magnetic Protists In A Chemically Stratified Coastal Salt Pond, Dennis A. Bazylinski, David R. Schlezinger, Brian H. Howes, Richard B. Frankel, Slava S. Epstein

Physics

Chemical stratification occurs in the water columns and sediments of many aquatic habitats resulting in vertical chemical and redox gradients. Various types of microorganisms are often associated with specific depths and chemical parameters in these situations. For example, magnetite-producing magnetotactic bacteria are known to form horizontal “plates” of cells at the oxic/anoxic transition zone (OATZ) of such environments. Here, we report the presence of populations of diverse magnetic protists in a seasonally chemically stratified, coastal salt pond. The protistan types included several biflagellates, a dinoflagellate, and a ciliate that were each associated with specific depths and thus, specific chemical, microbiological …

The Use Of Border Collies To Disperse Birds At Southwest Florida International Airport, Bobby D. O'Rick

2000 Bird Strike Committee-USA/Canada, 2nd Annual Meeting, Minneapolis, MN

Similar to many airports throughout the United States and Canada, Southwest Florida International Airport (RSW) has a number of development features attractive to wildlife. Such features include stormwater detention ponds, large expanses of open fields, natural wetland marshes, and mature trees. In order to maintain safe operations and minimize the potential for wildlife-aircraft collisions, RSW has expanded the existing wildlife harassment program to include the use of a border collie. An Ecological Study completed by the United States Department of Agriculture (USDA) in 1997 indicated regular use of the airfield throughout the year by wading birds, waterfowl, and blackbirds. Although …

Cancer Surveillance Series: Non-Hodgkin’S Lymphoma Incidence By Histologic Subtype In The United States From 1978 Through 1995, Frank D. Groves, Martha S. Linet, Lois B. Travis, Susan S. Devesa

Public Health Resources

Background: Clinical investigations have shown prognostic heterogeneity within the non-Hodgkin’s lymphomas (NHLs) according to histology, but few descriptive studies have considered NHLs by subgroup. Our purpose is to assess the demographic patterns and any notable increases in population- based rates of different histologic subgroups of NHL.
Methods: Using data collected by the Surveillance, Epidemiology, and End Results Program of the National Cancer Institute, we calculated incidence rates for the major clinicopathologic categories of NHL by age, race, sex, geographic area, and time period.
Results: Among the 60 057 NHL cases diagnosed during the period from 1978 through 1995, total incidence …

Feeding Behavior Of Crayfish Snakes (Regina) : Allometry, Ontogeny And Adaptations To An Extremely Specialized Diet, Roy Mark Waters

Doctoral Dissertations

Dietary specialists are often predicted to have specialized and stereotyped behaviors that increase the efficiency of foraging on their preferred prey, but which limit their ability to feed on nonpreferred prey. Although there is support for various aspects of this prediction, a number of studies suggest that specialists should not be characterized in such a simplified way. The purpose of this study was to describe the prey selectivity, prey handling behavior, and chemosensory behavior of crayfish snakes (Regina, Colubridae), which are extreme dietary specialists, and determine the effects of prey type, feeding experience and ontogeny.

Nutrient Absorption And Utilization By Wing And Flight Muscle Morphs Of The Cricket Gryllus Firmus: Implications For The Trade-Off Between Flight Capability And Early Reproduction, Anthony J. Zera, Tammy Brink

Anthony Zera Publications

Absorption efficiency (AD, approximate digestibility, assimilation efficiency) of various macronutrients and conversion of absorbed nutrients to biomass (ECD) were compared among the two types of flightless morph and the flight-capable morph of the cricket, Gryllus firmus. No biologically significant phenotypic or genetic difference in AD for carbohydrate, protein or lipid was observed among morphs fed either a high-nutrient (100%) or a low-nutrient (25%) diet. Thus, previously-documented differences among adult morphs in carbohydrate and lipid content must be caused by processes other than variation in nutrient absorption by morphs during adulthood. Relative absorption efficiency of total dry mass of food …

The Impact Of Lianas On Tree Regeneration In Tropical Forest Canopy Gaps: Evidence For An Alternative Pathway Of Gap‐Phase Regeneration, Stefan A. Schnitzer, James W. Dalling, Walter P. Carson

Biological Sciences Faculty Research and Publications

1 Regeneration in forest canopy gaps is thought to lead invariably to the rapid recruitment and growth of trees and the redevelopment of the canopy. Our observations, however, suggest that an alternate successional pathway is also likely, whereby gap‐phase regeneration is dominated by lianas and stalled in a low‐canopy state for many years. We investigated gap‐phase regeneration in an old‐growth tropical forest on Barro Colorado Island (BCI) in Panama to test the following two hypotheses: (i) many gaps follow a pathway in which they remain at a low canopy height and are dominated by lianas and (ii) the paucity of …

Scale, Ecological Fallacy, And The River Continuum Concept, Hope M. Childers

Graduate Theses, Dissertations, and Problem Reports

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 …

The Relationship Between Residential Status And Perception Of Psychological Separation Among Young College Students, Stephanie G. Raines

Theses

The purpose of this study was to examine the relationship between undergraduates' perception of psychological separation and residential status. Two groups of students, those who lived at home with their parents (n=3 I) and those who did not (n= 55), were surveyed using the Psychological Separation Inventory (PSI). Using the four subscale scores from the PSI, a t-test for independent samples found no significant relationship between residential status and psychological separation. Additional statistical analysis failed to find a relationship between the scores and independent variables such as gender, age and years in college. It was concluded that this research failed …
