Landowners Perceptions Of Crop Damage From White-Tailed Deer In South Carolina, Webb M. Smathers Jr., Gary R. Stratton, Derrell Shipes
Landowners Perceptions Of Crop Damage From White-Tailed Deer In South Carolina, Webb M. Smathers Jr., Gary R. Stratton, Derrell Shipes
Eastern Wildlife Damage Control Conference: 6th (1993)
Survey respondents reported a definite increase in the population of white-tailed deer (Odocoileus virginianus) in South Carolina. Almost 73% of the producers from a random sample indicated that deer populations have increased over the five year period preceding 1991. With a higher deer population, crop damage from deer became more prevalent, and 72% of the producers indicated having some level of damage. The producers in the sample had mixed feelings about the damage their crops received with 70% indicating that the damage was either negligible or was tolerable in exchange for having deer around. In South Carolina the increasing deer …

Chloroform Contamination In The Louisville Aquifer: An Investigation Of Its Occurrence And Propagation, Sergio E. Serrano
KWRRI Research Reports
This report presents the main results of an investigation on the nature and propagation of an accidental spill of chloroform in the Louisville aquifer, Kentucky. Much of the effort is concentrated on the development of mathematical models to either reconstruct the history of evolution of the plume, or forecast its propagation in the future. Chloroform is a dense halogenated solvent which exhibits a special migration pattern in porous media: Because of this and the relative absence of a conceptual theory on its hydrodynamics in porous media, meaningful predictive models will have to deal with many unresolved theoretical aspects of contaminant …

Migration And Dispersal Of Laughing Gulls In The United States, Jerrold L. Belant, Richard A. Dolbeer
United States Department of Agriculture Wildlife Services: Staff Publications
The 3662 recovery records for Laughing Gulls (Larus atriczlla) banded in North America from 1924 to 1991 were analyzed to determine migration and dispersal patterns for Northeast (Maine to Virginia) and Gulf Coast (west coast of Florida to Texas) populations. Autumn migration for Northeast Laughing Gulls was initiated in October. Northeast Laughing Gulls migrated greater distances and were recovered farther south during winter than Gulf Coast gulls. Significantly more Gulf Coast Laughing Gulls wintered along the Gulf Coast than did Northeast Laughing Gulls. In contrast, significantly more Northeast Laughing Gulls wintered in Central and South America. Adult Laughing Gulls returned …
Toward Conservation Of Midcontinental Shorebird Migrations, Susan K. Skagen, Fritz L. Knopf
Toward Conservation Of Midcontinental Shorebird Migrations, Susan K. Skagen, Fritz L. Knopf
United States Department of Agriculture Wildlife Services: Staff Publications
Shorebirds represent a highly diverse group of species, many of which experience tremendous energy demands associated with long-distance migratory flights. Transcontinental migrants are dependent upon dynamic freshwater wetlands for stopover resources essential for replenishment of lipid reserves and completion of migration. Patterns of shorebird migration across midcontinental wetlands were detected from migration reports to American Birds and information provided by U.S. Fish and Wildlife Service national wildlife refuges. Patterns in species composition and abundance varied geographically, emphasizing the uniqueness of different regions to migrating shorebirds. Smaller species and neotropical migrants moved primarily across the Great Plains, whereas larger species and …

Evaluation Of The Total Petroleum Hydrocarbon Standard For Cleanup Of Petroleum Contaminated Sites, Rick A. Blaisdell, Mark E. Smallwood
Evaluation Of The Total Petroleum Hydrocarbon Standard For Cleanup Of Petroleum Contaminated Sites, Rick A. Blaisdell, Mark E. Smallwood
Theses and Dissertations
This study evaluated the TPH (total petroleum hydrocarbon) cleanup standard for petroleum contaminated soils (PCS). A survey of 13 state regulators was performed to characterize current standards and regulatory viewpoints on the use of a TPH versus a BTEX cleanup standard. The regulatory community considers the BTEX constituents the greatest threat to groundwater, yet expressed concern that the use of a compound specific standard, without an accompanying analysis for TPH, might result in residual soil contamination that may present risk. This study also evaluated the ratio of BTEX TPH in soil over time. Based on JP-4 contaminated site soil data, …
Analytical Modeling Of Aquifer Decontamination By Pulsed Pumping When Contaminant Transport Is Affected By Rate-Limited Sorption And Desorption, Thomas A. Adams, Robert C. Viramontes
Analytical Modeling Of Aquifer Decontamination By Pulsed Pumping When Contaminant Transport Is Affected By Rate-Limited Sorption And Desorption, Thomas A. Adams, Robert C. Viramontes
Theses and Dissertations
This research explores radially convergent contaminated transport in an aquifer towards an extraction well. This thesis presents the equations governing the transport of a contaminant during aquifer remediation by pulsed pumping. Contaminant transport is assumed to be affected by radial advection, dispersion, and sorption/desorption. Sorption is assumed to be either equilibrium or rate-limited, with the rate-limitation described by either a first-order law, or by Fickian diffusion of contaminant through layered, cylindrical, or spherical immobile water regions. The equations are derived using an arbitrary initial distribution of contaminant in both the mobile and immobile regions, and they are analytically solved in …

Vadose Zone Contamination Measurement And Modeling, Thomas A. Reeder
Theses and Dissertations
This thesis investigated the effects of the slow sorption mechanism on the transport of volatile organic contaminants in the vadose zone. Recent research has shown that slow sorption may have a significant impact on the transport of volatile organic compounds in the subsurface. Specifically, this document examined the effects of slow sorption on the Vapor Extraction System (VES) and the Purge and Trap Measurement System. It was found that the slow sorption of organic molecules on soil may profoundly influence the efficiency of VES and purge and trap. In addition, this thesis investigated possible alternatives to purge and trap, including …
A Plan For Coordinating Department Of Defense Emissions Trading, Charles H. Weir
A Plan For Coordinating Department Of Defense Emissions Trading, Charles H. Weir
Theses and Dissertations
The original purpose of this research was to develop a plan to coordinate emissions trading between DoD installations. During the course of this research, findings indicated that restrictions on emissions trading would make such a plan of limited applicability. However, findings did indicate the need for a tool to assist managers with selecting the netting, offset, and banking emissions trading alternatives. Developing this tool became the objective of this research. This objective was fulfilled by developing a management guide to assist environmental managers with selecting the emissions trading alternatives netting, banking, and offsets. Background information was collected by examining literature …

United States Department of Agriculture Wildlife Services: Staff Publications
Animal welfare considerations and regulations serve to ensure that experimental animals are used wisely while minimizing stress. Substantial impacts on the use of animals in experiments have resulted, thereby increasing the challenges for designing studies and analyzing data to provide valid inferences. Statisticians should become more indispensable for involvement in study design (including Animal Care and Use Committees), application of appropriate analyses, prudent interpretation of results, and the development of new statistical techniques to meet these needs.
