Quantitative Comparison Of Fecal Coliform And Fecal Streptococci Counts Of Six Ponds In Charlotte Sounty, Virginia, Melissa Dunn Back Oct 2001

Quantitative Comparison Of Fecal Coliform And Fecal Streptococci Counts Of Six Ponds In Charlotte Sounty, Virginia, Melissa Dunn Back

Theses & Honors Papers

Performing testing to detect for the presence of fecal coliform and fecal streptococci are the acceptable standard methods for judging the quality of water. Their presence and quantitation are presumed to be a predictive indicator of potentially more serious organisms being present. This study was initiated to look at the differences in fecal coliform counts between irrigation ponds and livestock ponds. The hypothesis was that livestock ponds would have a significantly higher count of fecal coliform and fecal streptococci than irrigation ponds. This hypothesis was accepted. Six privately owned ponds in Charlotte County, Virginia were used to evaluate for the …

Can A Little Ice Age Climate Signal Be Detected In The Southern Alps Of New Zealand?, Jessica L. Black Aug 2001

Can A Little Ice Age Climate Signal Be Detected In The Southern Alps Of New Zealand?, Jessica L. Black

Electronic Theses and Dissertations

The Little Ice Age (LIA) was a late Holocene interval of climate cooling registered in the North Atlantic region by expansion of alpine glaciers and sea ice (Grove, 1988). Here the LIA includes an early phase from about AD 1280 to AD 1390, along with a main phase from about AD 1556 to AD 1860, followed by warming and ice retreat (Holzhauser and Zumbiihl, 1999a). It has recently been demonstrated from records of North Atlantic ice-rafted debris that the LIA is the latest cooling episode in a pervasive 1500-year cycle of the climate system that may lie at the heart …

A Comparison Of Phytoplankton Communities In Lake Prince And The Western Branch Reservoir, Suffolk, Virginia, Cara Marie Muscio Apr 2001

A Comparison Of Phytoplankton Communities In Lake Prince And The Western Branch Reservoir, Suffolk, Virginia, Cara Marie Muscio

Biological Sciences Theses & Dissertations

Lake Prince and the Western Branch Reservoir are two eutrophic bodies of water located in Suffolk, Virginia. Lake Prince and its two small tributaries join the Western branch via a constructed spillway. This lake system is a source of water for the surrounding municipalities, and a recreational area for community citizens. In the past, these bodies of water had repeated incidents of low oxygen and nuisance algal blooms, particularly cyanobacteria species. As a result aerators have been installed in the main body of both Lake Prince and the Western Branch Reservoir. In addition, a pipeline has been installed from North …

Effects Of Human Disturbances On The Behavior Of Dabbling Ducks, Melissa Lynn Pease Apr 2001

Effects Of Human Disturbances On The Behavior Of Dabbling Ducks, Melissa Lynn Pease

Biological Sciences Theses & Dissertations

Disturbance of wintering and migrating birds by human activities can cause birds to expend energy in avoidance of humans and reduces the time available for resting and feeding at a time in the annual cycle when fat deposition and energy conservation are important. Also, human disturbances can effectively cause habitat loss by displacing birds from feeding or resting habitat. Managers of natural resources are increasingly faced with decisions about the types and amounts of public use that should be allowed without lowering the value of the resource for wildlife. In order for managers to make decisions about how to minimize …

Adequacy Of Terrestrial Fauna Surveys For The Preparation Of Environmental Impact Assessments In The Mining Industry Of Western Australia [Thesis], Jason L. Fraser Jan 2001

Adequacy Of Terrestrial Fauna Surveys For The Preparation Of Environmental Impact Assessments In The Mining Industry Of Western Australia [Thesis], Jason L. Fraser

Theses : Honours

The Environmental protection Authority has indicated that terrestrial fauna surveys as undertaken for the purpose of preparing Environmental Impact Assessment (EIA) are not providing adequate information to enable decision-makers to assess development impacts on biodiversity and ecosystems. In the absence of a protocol to assess current standards of terrestrial fauna surveys, 'best practice' was defined through discussions held with an 'expert panel', and quantified through a questionnaire. This study examined current standards of terrestrial vertebrate fauna surveys, prepared for the purpose of EIA, with 'best practice' as defined by relevant expert opinion. Strengths and weaknesses of terrestrial fauna surveys were …

An Evaluation Of Environmental Disclosures Produced In Australian Local Government Annual Reports, Royston J. Tan Jan 2001

An Evaluation Of Environmental Disclosures Produced In Australian Local Government Annual Reports, Royston J. Tan

Theses : Honours

This thesis is an evaluation of the environmental disclosures published in Australian local governments' annual reports. The study is aimed in identifying disclosures of environmental information by Australian local governments and providing explanations for the variations in the quantity and quality of information disclosed. Various social responsibility theories were used in this study. The theories employed in this study were institutional factors, stakeholder theory, social and political theories. Institutional factors included issues such as local government characteristics and pressures exerted from various government and non·government organizations to implement and disclose environmental measures. A content analysis methodology was used in this …

Abundance, Distribution And Population Characteristics Of Western Grey Kangaroos (Macropus Fuliginosus, Desmarest 1817) In Yellagonga Regional Park, Amy Chang Jan 2001

Abundance, Distribution And Population Characteristics Of Western Grey Kangaroos (Macropus Fuliginosus, Desmarest 1817) In Yellagonga Regional Park, Amy Chang

Theses : Honours

Yellagonga Regional Park is located in the northwest corridor of Perth and constitutes 1400 hectares of wetlands, parkland, open forest and open woodland. Few studies have been conducted on the native fauna in the Park's upland habitats. For this reason, a study of the abundance and distribution of western grey kangaroos (Macropus fuliginosus) was conducted. A walked survey using direct counts and individual recognition of kangaroos during winter, recorded a total of 123 kangaroos, 51 pouch young and 23 unidentified individuals in Yellagonga Regional Park, and a further 24 kangaroos and 18 pouch young at Edith Cowan University's Joondalup campus. …

The Assessment Of Satellite Remote Sensing As A Tool For Determining Sea Surface Temperatures In Nearshore Environments, Fabienne Faskel Jan 2001

The Assessment Of Satellite Remote Sensing As A Tool For Determining Sea Surface Temperatures In Nearshore Environments, Fabienne Faskel

Theses : Honours

The use of satellite remote sensing for environmental management applications has seen a marked increase over the past decade. Remotely sensed data are obtainable for a variety of parameters, such as mineral exploration, species migration, and for determining sea surface temperatures (SSTs). This study examined whether satellite remote sensing is a viable option for determining SSTs in coastal waters, as traditionally this application has only been applied to open-ocean, offshore waters. SSTs in the nearshore waters of Rottnest Island, Western Australia, were determined using in situ temperature loggers and remotely sensed satellite data. Initially the accuracy of the satellite sea …
