Reefs As Contributors To The Diversity Of Epiphytic Algal Communities In Seagrass Meadows, B. R. Van Elvan Jan 1998

Reefs As Contributors To The Diversity Of Epiphytic Algal Communities In Seagrass Meadows, B. R. Van Elvan

Theses : Honours

It has recently become dogma that reef systems arc a source of diversity to algal epiphyte communities in adjacent seagrass meadows. While this theory had not been tested, it was often cited as the reason for unexpected results in algal studies and marine pollution monitoring. This study examined whether reefs do in fact contribute to the diversity of seagrass epiphytes by testing the effect of distance from reef on seagrass epiphyte communities. The study was conducted in the vicinity of Carnac and Garden Islands and Parmelia Bank, off the coast of Fremantle, Western Australia. Three habitat types were selected as …


The Soil Acarine Fauna Of Selected Agroecosystems Within The York Shire, Derek Juan Swarts Jan 1998

The Soil Acarine Fauna Of Selected Agroecosystems Within The York Shire, Derek Juan Swarts

Theses : Honours

The practice of broadacre, dryland farming is known to affect the physico-chemical structure of the soil but our knowledge or its impact on the biological structure is rudimentary. The soil acarine (mite) communities which inhabit these soils display a variety of responses to this agricultural practice. With the increasing focus on developing ecologically sustainable agricultural techniques, an understanding of the soil acari becomes increasingly important. This study investigated the impact of two agricultural practices (designated here us Conventional and Non-Conventional) upon the abundance and diversity of the soil acari. Conventional agricultural practice involved broad scale chemical application to weeds and …


The Birds And Habitat Of Kings Park, Bradley W. Cox Jan 1998

The Birds And Habitat Of Kings Park, Bradley W. Cox

Theses : Honours

Kings Park is a large urban park in the centre of Perth with extensive areas of semi-natural bushland. The park is an important refuge for birds in the metropolitan area but is losing species through habitat disturbance. Understanding the way in which birds are related to their habitat helps to understand the effect of habitat disturbance on the bird community. The aim of this project was to generate guidelines which will aid in the management and conservation of birds in the park, through an understanding of the relationship of the birds to their habitat. The avifauna and various habitat factors …


1080 Operational Procedures Manual - Second Edition, Agriculture Western Australia Jan 1998

1080 Operational Procedures Manual - Second Edition, Agriculture Western Australia

Biosecurity published reports

Sodium fluoroacetate (1080) is an extremely toxic substance which can be a danger to humans if handled incorrectly. At the same time 1080 is the most effective and efficient poison for the control of Western Australia's main vertebrate pest species including rabbits, wild dogs and foxes. One of the main reasons for its usefulness in Western Australia is that many native animals have a high tolerance to it and so may not be affected by baiting.

Industry Resource Protection Program (IRPP) This program, part of Agriculture Western Australia, supports feral animal control carried out by its staff and community groups. …

Northern Australia Quarantine Strategy. Weeds Target List, B. M. Waterhouse, A A. Mitchell

Biosecurity published reports

Second edition.

The Northern Australia Quarantine Strategy (NAQS) was established in 1989 as an outcome of a major evaluation of quarantine in Australia (AGPS 1987, 1988). NAQS activities include surveying for weeds,insect pests and diseases of plants; and pests and diseases of animals in northern Australia, Papua New Guinea and Indonesia. The primary goal is to provide early detection and warning of new quarantine threats or incursions.

A targetted approach was adopted for all pests, diseases and weeds. For each category of pest, experts in the discipline compiled lists of organisms not known from Australia but known to occur in …

Protection Of Bangladesh Waters Against Accidental Oil Pollution From Ships, Khondaker Md. Asaduzzaman

World Maritime University Dissertations

Bangladesh, as being a flag, coastal and port state, has a genuine concern about the threat of oil pollution from marine transportation in its waters. However, her concern for accidental oil pollution from ships is not adequately matched by appropriate preventive and remedial measures. As a result, the country continues to be in an absolutely vulnerable position with respect to the dangers of oil pollution. This dissertation is a study of the need for and the ways of protecting the marine environment of Bangladesh from oil pollution incidents. The threats of accidental spills in Bangladesh waters are discussed and the …


Continuation Of Illinois River Water Quality Monitoring Of Moores Creek, Paul F. Vendrell Dec 1997

Continuation Of Illinois River Water Quality Monitoring Of Moores Creek, Paul F. Vendrell

Arkansas Water Resources Center Technical Reports

In Northwest Arkansas, nutrients transported by surface water are a major concern. These nutrients are implicated in causing water quality impairment of lakes in Northwest Arkansas and eastern Oklahoma. The nutrients of concern are nitrogen and phosphorus. Nitrogen and phosphorus stimulate algae production in water bodies and can cause objectionable water quality. Problems associated with algae growth are aesthetic impairment, objectionable taste and odor of potable water, interference with recreation activities, and fish kills in some hyper-eutrophic cases. The sources of these nutrients are primarily from land application of confined animal wastes as soil amendments to pastures. In 1990, the …

Preliminary Investigation Of The Extent And Effects Of Sediment Contamination In White Lake Near Whitehall Leather Tannery, Richard Rediske, Gary Fahnenstiel, Tom Nalepa, Peter Meier, Claire Schelske Dec 1997

Preliminary Investigation Of The Extent And Effects Of Sediment Contamination In White Lake Near Whitehall Leather Tannery, Richard Rediske, Gary Fahnenstiel, Tom Nalepa, Peter Meier, Claire Schelske

Scientific Technical Reports

By using a combination of chemistry, toxicological evaluation, ecological analysis, and radiodating, this investigation has defined the ecological effects and the nature and extent of sediment contamination in the Tannery Bay area of eastern White Lake. The sediments in Tannery Bay represent a source of chromium transport for most of the eastern basin of White Lake. The recent deposition of chromium contaminated sediments exceeding 500 mg/kg in down gradient locations shows that export processes are responsible for the movement of this material from Tannery Bay. Arsenic and mercury appear to be less mobile and are retained in the sediments of …

Pesticide-Related Health Problems And Illness In Farm-Workers In The United Arab Emirates, Mahra Mohammed Mahmood Beshwari Dec 1997

Pesticide-Related Health Problems And Illness In Farm-Workers In The United Arab Emirates, Mahra Mohammed Mahmood Beshwari

Theses

Arabian Gulf countries, witnessed rapid development in many aspects of life. Although these

developments have improved the quality of life in the UAE, they have drawbacks that generated

health problems and environmental hazards. One of the consequences of rapid development is the

usage of large amounts of pesticides in agricultural production for the sake of increasing the yield of crops. However, the expanded use of these pesticides is known to result in acute respiratory symptoms and changes in body metabolism. To-date, no population-based study has been conducted to investigate the effects of pesticides on plasma amino acids and liver enzyme …

Management Options For Pilbara Demersal Line Fishing, Gaye Looby Nov 1997

Management Options For Pilbara Demersal Line Fishing, Gaye Looby

Fisheries Management Papers

Fisheries Western Australia licensing arrangements allow all vessels with an unrestircted fishing boat licence ('wetline licence') to take scalefish throughout the State. These arrangements have led to a high level of excess capacity in the licensed 'wetline' fishing fleet to exploit the scalefish resources. The declaration of the Kimberley Interim Line Fishery and forthcoming declaration the Northern Demersal Scalefish Fishery have resolved this problem for the Kimberley waters. However, the high level of excss capacity in the 'wetline' fleet to exploit the waters of the Pilbara remains a problem Preview access and develop a management plan for the Pilbara demersal …

Removal And Recovery Of Vocs And Oils From Surfactant-Flushed Recovered Water By Membrane Permeation, Ashish Nagnath Saraf Oct 1997

Removal And Recovery Of Vocs And Oils From Surfactant-Flushed Recovered Water By Membrane Permeation, Ashish Nagnath Saraf

Theses

Surfactant-enhanced subsurface remediation appears to be capable of removing efficiently contaminants from the source area as well as the concentrated plume. Initial research was conducted on separate removal of trichloroethylene (TCE) and an oil. It was found that oil permeation and modified pervaporation are effective techniques of removing oil and TCE respectively from the simulated feed. It was found that the oil permeation technique can effectively remove 98-99% of oil from an oil-in-water emulsion. The subsurface-entrapped organic pollutants often have high boiling components along with the VOCs. A combined permeation technique is applied here to simultaneously remove TCE and n-dodecane …

Development Of An Integrated Canada Goose Management Program In Virginia, Martin Lowney, Phil Eggborn, Gary Costanzo, Don Patterson

Wildlife Damage Management Conference

Wildlife managers in the State of Virginia developed an integrated Canada goose (Branta canadensis) damage management program in 1996 to address increasing damage caused by resident (non-migratory) Canada geese, primarily in urban/suburban areas. The previous Canada goose damage management program relied primarily on harassment and relocation. The integrated program was made available to citizens, homeowner associations, businesses, organizations, city and county governments, and state and federal agencies in 1997. The Integrated Canada Goose Management Program was developed by U.S. Department of Agriculture-Animal and Plant Health Inspection Service-Wildlife Services, Virginia Department of Agriculture and Consumer Services, Virginia Department of …

Developing Urban Deer Management Plans: The Need For Public Education, Deborah Green, Glen R. Askins, Phillip D. West

Wildlife Damage Management Conference

Independent public opinion surveys concerning urban deer (Odocoileus virginianus) management were conducted in two Virginia communities. A total of 346 citizens were interviewed in two Random Digit Dial telephone surveys. In addition to questions concerning management techniques and their administration, participants were asked about their experience with deer, their awareness of problems with deer in the area, and their enjoyment of deer. In both localities, non-lethal controls were preferred over lethal controls; trapping and relocation, fencing, repellents, and birth control measures were favored by a majority of residents. The only lethal control acceptable to residents in both communities …


Historical Forces Shaping Americans' Perceptions Of Wildlife And Human-Wildlife Conflicts, Michael R. Conover, Denise O. Conover Oct 1997

Historical Forces Shaping Americans' Perceptions Of Wildlife And Human-Wildlife Conflicts, Michael R. Conover, Denise O. Conover

Wildlife Damage Management Conference

From colonial times until the 19th century, the dominant American view of wildlife and its management was dualistic—wildlife species were divided into good animals (those which had commercial value or could be eaten) or bad animals (those which threatened the colonists’ safety or food supply). Philosophically, early colonial Americans believed that the environment was to be manipulated for man’s purposes. Under the impact of modernization, Darwinian influence, over-exploitation of resources, and environmentally-conscious professionals, Americans in the late 19th century began to appreciate the recreational value of wildlife and to develop a more protective attitude toward it. Still the dichotomy between …


Private Nuisance Wildlife Control: Is There A Future In Kansas?, Charles Lee, Philip Gipson, Lucas Koch Oct 1997

Private Nuisance Wildlife Control: Is There A Future In Kansas?, Charles Lee, Philip Gipson, Lucas Koch

Wildlife Damage Management Conference

The private industry involvement in nuisance animal damage control is increasing in Kansas. Improved oversight of that industry is needed and the Kansas Department of Wildlife and Parks (KDWP) plans to implement a mandatory education and certification program beginning in 1998. KDWP currently issues permits to individuals who wish to trap or control nuisance animals outside of normal harvest seasons. Individuals who have held these permits to conduct nuisance animal damage control were surveyed in 1995 to better understand the status and needs of that industry in Kansas. A 3-page mail survey was sent to all 93 permit holders. Raccoons …


Wildlife-Caused Losses For Catfish Producers In 1996, Alice P. Wywialowski Oct 1997

Wildlife-Caused Losses For Catfish Producers In 1996, Alice P. Wywialowski

Wildlife Damage Management Conference

In January 1997, the National Agricultural Statistics Service (NASS) surveyed catfish producers about wildlife-caused losses in 1996, Of the 1,465 catfish producers in 15 states surveyed, 1,008 (68.8%) agreed to complete the survey. Surveys were conducted primarily by telephone, but some producers received mail surveys. The response rated varied among states. The majority of catfish producers were in Mississippi (n=-300), followed by Alabama (n=163), and then Arkansas (n=117). The remaining states each had < 100 respondents. Data were analyzed for 6 regions, each with a sample size of > 100 respondents. Overall, 69% of catfish producers cited a wildlife-caused loss of catfish. Producers cited losses to wildlife most frequently in Mississippi (81%), followed by states adjoining …

Electric Fencing Reduces Heron Predation At Northeastern Trout Hatcheries, Mark E. Tobin, James F. Glahn, Erica S. Rasmussen

Wildlife Damage Management Conference

Great blue herons (Ardea herodius) are the most common avian predator at commercial trout hatcheries in the northeastern United States. We evaluated a 2-strand electric fence for excluding this species from raceways at 2 commercial trout hatcheries in central Pennsylvania. Fences consisted of high density polyethylene 400-lb strength tape supported by fiberglass posts and energized by either a battery-powered or a solar-powered fence charger. Labor and material for constructing the fences at the 2 sites averaged $1.32/m of raceway. Bird visitation at the 2 sites initially declined, but returned to pre-installation levels. However, bird use of raceways declined …

Attempted Relocation Of A Ring-Billed Gull Roost At Washington National Airport, Jessica Dewey, Martin Lowney Oct 1997

Attempted Relocation Of A Ring-Billed Gull Roost At Washington National Airport, Jessica Dewey, Martin Lowney

Wildlife Damage Management Conference

Gulls, particularly ring-billed gulls [Larus delawarensis], have been identified as a threat to aircraft operations at Washington National Airport (now Ronald Reagan National Airport) in northern Virginia. Through bird surveys conducted in 1992, 1993, and 1997, an estimated 7,000 gulls were observed roosting during winter on the Potomac River near the airport. A harassment program was run on 5 consecutive evenings, 24-28 February 1997, to relocate the roosting gulls. Six to 8 people shot pyrotechnics from shore and 2 boats for 2 hours prior to dusk each evening. Each evening the gulls arrived consistently later than the prior …


Double-Crested Cormorant And Ring-Billed Gull Damage Management On Lake Champlain: Are Basin-Wide Objectives Achievable?, Richard Chipman, Dennis Slate, Larry Garland, David Capen Oct 1997

Double-Crested Cormorant And Ring-Billed Gull Damage Management On Lake Champlain: Are Basin-Wide Objectives Achievable?, Richard Chipman, Dennis Slate, Larry Garland, David Capen

Wildlife Damage Management Conference

Ring-billed gulls (Larus delewarensis) and double-crested cormorants (Phalacrocorx auritus) have nested on Lake Champlain since 1949 and 1982, respectively. Recent increases in cormorant nesting populations and pioneering activities of both species to previously uncolonized islands have resulted in impacts related to accumulation of bird guano and interspecific competition with less common species. Of primary concern are: decreases in wildlife and plant diversity on islands; reduced aesthetics and property values of island associated with the loss of trees; and predation or competition for nesting space with other species such as the state-endangered common tern (Sterna hirundo …
