Determining The Mobility Of Metals Through Coal Combustion Byproducts In Surface Impoundments By Analyzing Leachate From Modified Saturated Hydraulic Conductivity Tests, Michael Joseph Trofinoff

Theses and Dissertations

Surface impoundments are used extensively throughout the utility industry to store the combustion byproducts, or ash, from coal-fired generating facilities. Following combustion, the metals, naturally contained within coal at low concentrations, may become highly concentrated within the ash. These combustion byproducts are then piped out in a water-ash slurry to the surface impoundments where the ash weathers to- a clay- like substance after approximately 10 years. It is feared that these metals that are contained within the ash could possibly leach into the ground and contaminate the local groundwater. Utilizing a open column percolation test to determine the hydraulic conductivity …

Land-Cover Detection And Landscape Structure Analysis In The Pachitea Basin, Peruvian Amazon, Daniel Gann

FIU Electronic Theses and Dissertations

Classification procedures, including atmospheric correction satellite images as well as classification performance utilizing calibration and validation at different levels, have been investigated in the context of a coarse land-cover classification scheme for the Pachitea Basin. Two different correction methods were tested against no correction in terms of reflectance correction towards a common response for pseudo-invariant features (PIF). The accuracy of classifications derived from each of the three methods was then assessed in a discriminant analysis using crossvalidation at pixel, polygon, region, and image levels. Results indicate that only regression adjusted images using PIFs show no significant difference between images in …

In coordination with the Department of Conservation and Recreation, the Department of Environmental Quality, the Chesapeake Bay Local Assistance Department and the Virginia Marine Resources Commission (VMRC), the Center for Coastal Resources Management at the Virginia Institute of Marine Science (VIMS) was contracted to develop a tool for local governments that would assist in the decision-making process for marina development. In particular, the agencies wanted to develop a visual representation of the VMRC Criteria for the Siting of Marinas or Community Facilities for Boat Mooring. This was accomplished by gathering available data sets and developing geographic information system (GIS) data …

Breeding Bird Community Response To Vegetation Succession In Hardwood Shelterwood Cuts In The Virginia Piedmont, Pamela Coleman

Theses & Honors Papers

Population declines of many Neotropical migrant bird species (NTMs) in parts or all of their North American breeding ranges have prompted concern regarding the conservation of these species. Many NTMs have specific habitat requirements and are thus negatively affected by habitat alteration. In eastern North America, habitats have changed significantly since European settlement and those changes have had different impacts on different suites of breeding birds. Forest birds are frequently identified as species particularly sensitive to habitat changes though, more recently,marked declines of shrubland or early successional songbirds have raised concern. My goal was to examine the effects of a …

A Socioeconomic And Biological Evaluation Of Current And Hypothetical Crappie Regulations In Sardis Lake, Mississippi: An Integrated Approach, Brian Dorr, Ian A. Munn, Keith O. Meals

USDA Wildlife Services: Staff Publications

We conducted a socioeconomic survey and review of existing biological data in an integrated evaluation of current and hypothetical fishery regulations on crappies Pomoxis spp. in Sardis Lake, Mississippi. The objectives of this study were to (1) assess angler acceptance of current and hypothetical harvest restrictions, (2) determine the recreational value of the crappie fishery to its participants, (3) estimate possible changes in recreational value based on angler responses to hypothetical regulations, and (4) integrate the results of the socioeconomic surveys with existing biological information. Using the travel cost method, we estimated mean expenditures at US$29.48 and average consumer surplus …

Field Evaluation Of Flight ControlTm To Reduce Blackbird Damage To Newly Planted Rice, John L. Cummings, Michael L. Avery, Owen Mathre, E. Allen Wilson, Darryl L. York, Richard M. Engeman, Patricia A. Pochop, James E. Davis Jr.

USDA Wildlife Services: Staff Publications

An effective, economic, and environmentally safe bird repellent is needed to reduce blackbird (Icterinae) depredations to newly planted rice. We evaluated Flight Control^TM, a 50% anthraquinone product, as a seed treatment for newly planted rice. We treated rice seed with Flight Control at a 2% (g/g) concentration (1% active anthraquinone) the day of planting. This concentration reduced the number of blackbirds (P=0.0003) using treated fields and blackbird damage to rice seed (P=0.0124). The chemical concentration of anthraquinone on rice seed averaged 0.79% (SE=0.06%) at planting; 0.39% (SE= 0.04%) at day I, 0.34% (SE=0.05%) at …

Effects Of Invasive Africanized Honey Bees (Apis Mellifera Scutellata) On Native Stingless Bee Populations (Meliponinae) And Traditional Mayan Beekeeping In Central Quintana Roo, Mexico, Christine Elizabeth Cairns

FIU Electronic Theses and Dissertations

The Maya of the Yucatan region have a long history of keeping the native stingless bees (subfamily Meliponinae). However, market forces in the last two decades have driven the Maya to favor the use of invasive Africanized honey bees (Apis mellifera scutellata) for producing large quantities of high quality honey which has an international market. Furthermore, the native bees traditionally used by the Maya are now disappearing, along with the practice of keeping them.

An interdisciplinary approach was taken in order to determine the social factors behind the decrease in stingless beekeeping and the ecological driving forces behind their disappearance …

Reconstructing Salmon Abundance In Rivers: An Initial Dendrochronological Evaluation, James M. Helfield, Robert J. Naiman, Deanne C. Drake

Environmental Sciences Faculty and Staff Publications

Decision-makers concerned with salmon or their stream habitats are faced with many persistent, difficult questions including: how large and variable were these populations before European settlement? Here, we examine the feasibility of reconstructing salmon abundance using links between marine nutrients carried upstream by Pacific salmon ( Oncorhynchus spp.) and growth of dominant riparian trees in two Alaskan systems. We employ standard dendrochronology methods and regression models to quantify relationships between annual tree-ring growth, salmon escapement, and the climate pattern that affects oceanic production of Northeast Pacific salmon stocks, the Pacific Decadal Oscillation (PDO). We find that known, annual salmon escapement …

Report To The Minister For Agriculture, Forestry And Fisheries By The Integrated Fisheries Management Review Committee, Department Of Fisheries

Fisheries management papers

The Integrated Fisheries Management Review Committee was established to develop a strategy to integrate the management and sustainable use of fish resources. The Committee’s report proposes an alternative management framework and a set of guiding principles for allocating fish stocks to ensure optimal benefits are realised for the WA community. The report does not, and was not intended to, address specific allocation issues in particular fisheries – this will be a function of the framework and processes put in place following this review.

A Perspective On Two Decades Of Policies And Regulations Influencing The Protection And Restoration Of Submerged Aquatic Vegetation In Chesapeake Bay, Usa, R J. Orth, Ra Batiuk, Pw Bergstrom, Ken Moore

VIMS Articles

Seagrasses along with many other species of freshwater rooted submerged macrophytes in Chesapeake Bay (collectively called SAV) underwent serious declines in population abundances in the 1970s and have not as yet rebounded to previous levels. Cooperative efforts by scientists, politicians, federal and state resource managers, and the general public have developed policies and plans to protect, preserve and enhance SAV populations of Chesapeake Bay. These include the Chesapeake Bay Agreements (1983, 1987, 1992, 1993, 2000), an SAV Management Policy and Implementation Plan for Chesapeake Bay and Tidal Tributaries (1989 and 1990), Chesapeake Bay Blue Crab Fishery Management Plan (1997), as …

Federal Consistency In New Jersey, Urban Harbors Institute, University Of Massachusetts Boston

Urban Harbors Institute Publications

A discussion paper prepared as part of a focus group on the topic of Federal Consistency in New Jersey.

In 1972, the U. S. Congress passed the Coastal Zone Management Act (CZMA), designed to “preserve, protect, develop, and where possible, to restore and enhance the resources of the nation's coastal zone.” The CZMA encouraged coastal states to develop and implement comprehensive management programs that balance the need for coastal resource protection with the need for economic growth and development within the coastal zone.

In the latter portion of the 1970s New Jersey developed a coastal management plan that was fully …

An Analysis Of Shoreline Development Risk For Secondary Dune Systems In Tidewater Virginia With Associated Management Recommendations, Lyle M. Varnell, C. Scott Hardaway Jr.

Reports

This project was done in response to concerns by environmental resource managers of historic and potential adverse impacts to Virginia’s secondary dune ecosystems. Virginia environmental regulatory programs have little decision-making authority over the use of secondary dunes as these areas are not included in the Coastal Primary Sand Dune Act (the Dunes Act). These areas function as estuarine edge habitat and provide natural upland erosion control, and are thus valuable to estuarine and coastal plain fauna and adjacent upland property owners.

Managing Nature In Today's World, Walter E. Howard

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

The objective of my talk is to help airport authorities better understand the turmoil they encounter when managing birds and other wildlife populations. Many are reluctant to manage birds and mammals because they know that it will inevitably stir up controversy. Especially this is true when the program includes lethal means. Many people think all problems can be resolved by using non-lethal frightening devices or by live-trapping offending animals and relocating them away from airports. There are some sound arguments as to why it is biologically, ecologically and ethically proper to even use lethal means to resolve some airport wildlife …

Mandatory Strike Reporting: The Time Has Come, Paul Eschenfelder

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

The reporting of wildlife collisions with aircraft in almost all places, worldwide, is voluntary. As a result data with which to design, manufacture and operate aircraft to mitigate this hazard is poor. Voluntary reporting of strikes has resulted in data collection rates in the USA of around 20%, and only about 9% of the reported strikes contain complete data on bird species. Aviation manufacturers also agree that collection of strike data is difficult, incomplete and without an industry best practice. Air carriers, when research is done, are amazed to find that strike rates may be eight times higher than their …

Bird Detection And Radar Wind Profilers, Scott Mclaughlin

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

Radar wind profilers (RWPs) are a very sensitive class of operational and research-grade meteorological radars designed specifically to detect clear air turbulence in the atmosphere. These systems have been designed with frequencies ranging from 50 MHz to 3 GHz and antenna sizes from about 1 m to >1 ha. Unlike NEXRAD systems, the antennas do not move or scan but rather are stationary and use phase-shifter arrangements to point the beam. Using the Doppler-shifted backscatter return, winds profiles can be measured from near the ground to as high as 20 km in 5- to 60-minute intervals. RWPs have been used …

As a follow-up to a paper presented at International Bird Strike Committee meeting #23 in 1996, discussing Transport Canada’s emphasis on education and awareness programs as a means to reduce bird hazards to aircraft, this paper will describe significant changes that have occurred in Canada since that time. The 1994 Government of Canada National Airports Policy led to the devolution of Canada’s major airports. Private sector airport authorities now operate these airports and Transport Canada’s focus has shifted from management by policy to one of regulatory oversight. In addition to building on the awareness program that was in place in …

Avian Hazard Control In Brazil: Essential Role Of The Aeronautical Accidents Prevention And Investigation Center - Cenipa, Luiz Claudio Magalhaes Bastos

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

Brazil built one of the world’s largest aeronautical infrastructures. The airport net is distributed along its vast territory, which shows a tremendous ecosystem variety. Having a large civilian aircraft fleet and also running second after Venezuela in catalogued bird species, Brazil has had problems related to bird strikes. Nevertheless, Brazil is made up of 26 States plus the Federal District. Thus, besides the Union Government, each state holds its own government structure. The states are divided into counties that also have their own administrative structure. The jurisdiction of each level of government is established by the Federal Constitution, laws and …

Effects Of Location And Phase Of Flight On The Behavioral Responses Of Birds To Aircraft: Preliminary Observations, T. C. Kelly, M. J. A. O'Callaghan, P. D. Bourke, L. Buurma, R. Bolger

2002 Bird Strike Committee-USA/Canada, 4th Annual Meeting, Sacramento, CA

Based on an earlier classification of avoidance movements shown by birds to moving aircraft (Kelly et al. 2001), we have studied the evading maneuvers of the rook (Corvus frugilegus) in relation to the phase of flight of air traffic at Dublin Airport, Ireland. The percentage of individuals which did not show avoidance movements was almost identical for approach/landing and take-off /climb-out movements. However, the nature of the avoiding-response in relation to the phase of flight was different. Thus 78% of responses were “Simple” in the approach/landing flight phase whereas only 5% were in this category during take-off. On …
