Availability Of Organochlorides And Accumulation In Populations Of Tadarida Brasiliensis (Free-Tailed Bat) And Eptesicus Fuscus (Big Brown Bat), Michelle Lee Smith

Theses and Dissertations

Organochlorides were historically effective in controlling a wide range of pests. However, organochlorides have proved to present many problems to the health and welfare of other organisms. Due to these problems, especially declines in wildlife populations, organochlorides were restricted in the 1970's and a majority of them were banned in the mid to late 1980's. The effects of organochlorides on bats such as Tadarida brasiliensis and Eptesicus fuscus have been intensively studied. The effects can range from problems with reproduction to mortality. My analysis of populations of T. brasiliensis and E. fuscus showed that organochlorides are still present in the …

Using The Index Of Biotic Integrity Of Fish Communities To Evaluate Habitat Quality In Middle Chattahoochee River Tributaries, Theodor W. Roever

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

This paper reviews the literature on public involvement in the context of public land management agencies with particular attention to public involvement activities in the National Park Service. A conceptual framework borrowed from small-group decision-making literature is presented to assist public land managers in determining the role and place of public involvement in the management process. A variety of public involvement techniques and data analysis methods is reviewed. A review of the literature suggests several recommendations for managers, including: clarify the goals of public involvement; focus on the public involvement process as well as the outcome; and use a variety …

Long Term Residual Effects Of A Nutrient Addition On A Barrier Island Dune Ecosystem, Susan M. Heyel

Biological Sciences Theses & Dissertations

In 1991, 150 m² were fertilized with nitrogen on three dunes on Hog Island, part of the Virginia Coast Reserve Long Term Ecological Research site, to examine plant community response to nitrogen addition. In 2000, the fertilized plots continued to exhibit a positive growth response. This study sampled the aboveground biomass, belowground biomass, and nutrient content of the experimental plots to examine the long- term patterns of nitrogen retention in a nitrogen limited system. Aboveground and belowground biomass was significantly greater in the fertilized plots than in the control plots. Aboveground biomass exhibited was significantly greater in control and …

Creep And Creep-Recovery Models For Wood Under High Stress Levels, Zhiyong Cai, Kenneth J. Fridley, Michael O. Hunt, David V. Rosowsky

Civil and Environmental Engineering and Construction Faculty Research

Forty small clear southern pine specimens were loaded under third-point bending to examine creep and creep-recovery behavior for wood under high stress levels. Stress levels of between 69% and 91% of the predicted static strength were applied for 23 h with 1 h allowed for recovery, and the resulting deflection vs. time behavior was studied. The experimental creep and creep-recovery behavior was modeled using modified power law functions. The results indicate that these functions provide the best fit to both primary and secondary experimental data. The empirical models can be used to simulate the viscoelastic behavior of wood under high …

Comparison Of Water Quality, Zooplankton Density, And Cover In Razorback Sucker (Xyrauchen Texanus [Abbott]) Spawning Areas Of Lake Mead And Lake Mohave, Michael E. Golden, Paul B. Holden, Southern Nevada Water Authority

Publications (WR)

Las Vegas Bay and Echo Bay in Lake Mead have small, self-sustaining populations of razorback sucker (Xyrauchen texanus [Abbot]). Increased productivity and cover have been hypothesized as reasons for successful recruitment of razorback sucker in Lake Mead. Conversely, reproduction has been documented on Lake Mohave, another lower Colorado River reservoir, but no recruitment has been observed. In 2000, BIO-WEST, Inc. was contracted by the Southern Nevada Water Authority to design and implement a study to examine nutrient levels, zooplankton density, and cover in areas with and without razorback sucker recruitment success. We sampled Echo Bay, Las Vegas Bay, and …

Closing The Loop: Recycling, Reformulation, And Reuse In Prince Edward, Amelia, Buckingham And Cumberland Counties, Andrea Louise Bridge

Theses & Honors Papers

Everything we do to the land, air, and water affects our quality of life on this planet. Since the beginning of time, human beings have generated and discarded trash. As the pollution of the United States continues to grow so have the problems with our nation's landfills. Americans throw away an average of 3.5 pounds of garbage per person each day, or approximately 160 million tons of it per year. Studies have been conducted that show that the majority of our trash consists of paper, yard trimmings, metal, plastics, glass, food wastes, rubber, leather, textiles, and miscellaneous inorganic materials.

Land Usage Impacts On Springhead Salamander Populations, At Callaway Extended Properties, Harris County, Georgia, Neil Allen Pearce

Theses and Dissertations

Recent scientific studies have indicated that anrphibian populations appear to be declining in many areas of the world or exhibiting local population fluctuations. Some of the reasons given for this population decline are associated with land usage, and the negative biological impacts of many forms of land management practices. A study was conducted at the Callaway Gardens Extended Properties in Pine Mountain Georgia which compared the local aquatic salamander populations of five spring -fed streams in the Cason J. Callaway Memorial Forest, and five spring-fed streams in the Lower Valley Area. Using a cat ch-per-unit -effort sampling methodology, a comparison …

Using Gis And Land Use Data To Select Candidate Reference Sites For Stream Bioassessment, John Robert Olson

Theses and Dissertations

GIS was used to select candidate reference sites in Georgia to characterize the reference condition by sub-ecoregion for a rapid bioassessment of streams statewide. Instead of relying on best professional judgment or previous knowledge of a limited number of sites, we performed an objective evaluation of cumulative impact on all catchments using land use data sets. These included road and impoundment data from DLGs and Multi-Resolution Land use Consortium data. Land use impairment was measured as percentages of forest, urban, pasture, row crops, and barren area for both the entire catchment and for 10, 40, and 130-m riparian buffers, road …

1080 Summary Information, Department Of Agriculture, Western Australia, Department Of Conservation And Land Management, Western Australia, Department Of Health, Western Australia

Biosecurity research reports

Fluoroacetate, the active ingredient of 1080, occurs naturally in toxic plants in Australia, South Africa, and South America. Manufactured I080 underpins most vertebrate pest control programs in Australia and New Zealand. Fluoroacetate occurs naturally in about 40 plant species in Australia with most of these plants restricted to the south-west of WA.

I080 was introduced to rabbit control programs in the early 1950s and therefore has a long history of proven effectiveness and safety in Australia. There have been few repo1ted problems associated with human safety, environmental persistence, bioaccumulation or impact on populations of non-target species.

In particular, I080 baits …

The Drought Monitor, Mark D. Svoboda, Doug Lecomte, Mike Hayes, Richard Heim, Karin Gleason, Jim Angel, Brad Rippey, Rich Tinker, Mike Palecki, David Stooksbury, David Miskus, Scott Stephens

National Drought Mitigation Center: Faculty Publications

There is a need for improved drought monitoring and assessment methods in the United States. Drought is the most costly natural disaster [Federal Emergency Management Agancy (FEMA 1995; Wilhite 2000)], but it is often neglected by developers of assessment and forecast products. Drought is more nebulous than other disasters and does not lend itself to traditional assessments or forecast methods. Its relatively slow onset and the complexity of its impacts are reasons for the new assessment methodology. Improvements in drought monitoring and forecasting techniques will allow for better preparation, lead to better management practices, and reduce the vulnerability of society …

Development Of Diagnostic Approaches To Determine Sources Of Anthropogenic Stress Affecting Benthic Community Conditions In The Chesapeake Bay, Daniel M. Dauer, Michael F. Lane, Roberto J. Llansó

Benthic Applications

Benthic macrofauna are an important component of estuarine ecosystems. These organisms are a food source for higher trophic levels including fishes and crabs (Virnstein 1977, 1979; Holland et al. 1980; Dauer et al. 1982) and birds (Botton 1984; Quammen 1984). Benthic macrofauna affect both the physical and chemical properties of the sediment and the overlying water column (e.g., Rhoads and Young 1970; Rhoads 1973; Aller 1978, 1980), influence nutrient cycling (Rowe et al 1975; Zeiteschel 1980; Flint and Kamykowski 1984), and are capable of directly controlling phytoplankton biomass in the water column (Cleorn 1982; Officer et al 1982; Cohen et …

Smart Growth And Land Acquisition Priorities, New England Environmental Finance Center

Land Conservation

It is well-known and generally accepted that all undeveloped land in New England cannot forever be protected from development; nor would this be a desirable goal, as continued economic development and population growth are near certainties. For these and other reasons, private land trusts and government agencies generally use explicit criteria to prioritize their land acquisition activities and prospects.

Much land protection in New England and elsewhere, however, has occurred without substantial attention to such land use needs as fostering the best locations for where people will live, businesses will locate, and infrastructure will be built to avoid degrading resources. …

Asian Carp: Key To Identification

National Invasive Species Council

Asian carp are large 39-40 in. (40-50 lb.) fish introduced into the U.S. by fish farmers in Southern states in the 1960’s and 70’s to control vegetation and algae blooms. Three of these species, the grass carp (Ctenopharyngodon idella), bighead carp (Hypophthalmichthys nobilis), and silver carp (Hypophthalmichthys molitrix) have been released or have escaped to the wild and are reproducing in many rivers and streams of the Mississippi River Basin. As they continue to expand their range, and show up in commercial and sport fish catches, a need has arisen to develop a simple …

Historical Overview Of Tampa Bay Water Quality And Seagrass Issues And Trends, J.O. R. Johansson

Reports

Historical (pre-1930s) seagrass meadows in Tampa Bay are believed to have covered 31,000 ha of the shallow bay bottom. Later, impacts to the bay from increasing population and industrial development of the Tampa Bay area have resulted in large seagrass losses. By 1982, approximately 8,800 ha of seagrass remained. Since 1982, Tampa Bay seagrass monitoring programs have recorded a reversal in the trend of seagrass loss, with the baywide seagrass cover increasing from 9,420 ha in 1988 to 10,890 ha in 1997. However, between 1997 and 1999 the trend again reversed with substantial losses recorded, specifically in the Old Tampa …
