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. …

Research outputs pre 2011

This report represents the vegetation component of a project designed to provide ongoing monitoring of wetland salinity and biological resources in wetlands of the agricultural zone of south-west Western Australia. Maintenance of wetland biological diversity in the agricultural zone is one of the major objectives of the Salinity Action Plan. Due to their low position in the landscape, wetlands are the habitat most affected by salinisation.

A Framework For River Restoration Planning : Considering Conceptual And Structural Perspectives From Case Studies Of The Liao River In China And The Kalgan River In Australia, Ye Sun

Theses: Doctorates and Masters

Over the last decade, restoration ecology has been considered a new paradigm for dealing with many of the environmental problems of river systems. It is also recognized that management decisions have a greater chance of being successful if they are based on a thorough understanding of a concept or a plan. A review of current studies on river restoration and river restoration planning revealed that managers and scientists have put a substantial emphasis on ecological science and technology in restoration, while many sociopolitical and economic elements have been de-emphasized Besides this, understanding and experiences of river restoration, especially those of …

Ecotoxicological Risks Of Potential Toxicants For Brown Tree Snake Control On Guam, John J. Johnston, Richard E. Mauldin, Peter J. Savarie, Joseph E. Brooks, Thomas M. Primus

United States Department of Agriculture Wildlife Services: Staff Publications

The brown tree snake (Boiga irregularis) is a nocturnal, arboreal, rear-fanged, mildly venomous, colubrid snake which can reach lengths of up to 2.3 m and weigh as much as 2 kg(1). Originally, the species' range included the northern and eastern coasts of Australia, Papua New Guinea and nearby islands (2). It is believed that sometime in the 19501s, that snakes were inadvertently transported from New Guinea to Guam, where they proliferated (3). By the mid-1960’s, marked decreases in Guam's bird life were observed. By the mid-1980’s, snake densities were estimated at 50 to 100/hectare (13,000 to 26,000/sq mile), …

Farming Systems To Manage Salinity. Farmer Directed Research, Development And Extension. Research Results 2001, Richard Olive

Natural resources published reports

More and more of Western Australia's agnicultural lands are becoming saline. Currently it is estimated that about 18 milliion ha of land are affected to a greater or lesser degree by salinity causing production losses estimated at about $70 million a year.

Unless ways are found to halt and reverse the salinisation of land it is estimated that another 4.4 million ha could become saline over the next 50 years.

Grain growers and the Federal Government, through the Grains Research and Development Corporation (GRDC). are investing $12 4 million in R&D across Australia to develop productive solutions to the salinity …

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 …

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 …

Mine Dewatering In Arid, Saline Environments In Western Australia: The Response Of Biota Emerging From Rehydrated Sediments, Charelle Harkins

Theses : Honours

Mine dewatering is a critical part of the mining process to prevent flooding of underground or open pits, to allow for the excavation of the available resources. Groundwater is abstracted from underground pits to the surface through extraction bores. The issue of where to discharge the excess water is a major concern. The use of natural wetlands is one option for mine water discharge. Saline lakes in arid areas are ideal receiving environments for discharge options, acting as evaporation facilities for the storage and disposal of excess mine water. Mine water discharge into ephemeral lake systems modifies the volume of …

Fluvial Processes And Passive Rehabilitation Of The Lisbon Bottom Side-Channel Chute, Lower Missouri River, Robert B. Jacobson, Mark S. Laustrup, Michael D. Chapman

United States Army Corps of Engineers, Omaha District

Multiple large floods in 1993-1997 on the Lower Missouri River carved a side-channel chute through the river bottom at Lisbon, Missouri. Although similar in some respects to engineered side-channel chutes designed for habitat rehabilitation projects, the Lisbon Bottom chute has been unique in that it was allowed to evolve for more than four years with minimal stabilization. During the wet years, 1996-1999, the chute was subjected to abnormally high discharges and passed as much as 20% of the total discharge of the Missouri River. Relatively unrestrained fluvial processes during this time created a wide channel with highly diverse habitats. The …

So You Want To Work With Wolves?, John A. Shivik

United States Department of Agriculture Wildlife Services: Staff Publications

Growing up with three older sisters was a bit like being raised by wolves. One of their favorite games was called “stop hitting yourself.” To play, I was immobilized, and then with my arms overpowered, I was forced to repeatedly pummel my own noggin while they uttered the name of the game. Watching yourself hit yourself, feeling the pain and humiliation, yet being unable to stop is somewhat like being a federal biologist working with wolves. I’ve learned humility from my experiences but also formed the opinion that if you want to work with wolves, first consider medication; if that …

Design Of A Laboratory Secondary Hazard Study, David A. Goldade, Peter J. Savarie, Jerome C. Hurley, Stanley A. Gaddis, John J. Johnston

United States Department of Agriculture Wildlife Services: Staff Publications

Factors influencing the design and execution of a secondary hazard study are presented using the anticoagulant rodenticide, difethialone, as a model. Frequently, regulatory agencies require a determination of the potential hazard posed to non-target species by the application of pesticides. This hazard can occur through: 1) primary hazard, direct consumption of the bait or formulation containing the pesticide, or 2) secondary hazard, indirect consumption of the pesticide via ingestion of biological matrices such as animals or plants containing pesticide residues. In making this determination, the selection of appropriate test species as well as routes and level of exposure are critical. …

Introduction To Pesticides And Wildlife, John J. Johnston

United States Department of Agriculture Wildlife Services: Staff Publications

A pesticide is a substance intended for destroying, repelling or mitigating any animal, microorganism or plant pest. While pesticides are commonly chemical agents, biological or physical agents can also be pesticides. Many people equate the term pesticide with insecticide. However, there are a plethora of pesticides for which insects are not the target pest. Examples include herbicides, fungicides, rodenticides, acaricides, larvacides, etc. Additionally, pesticides are not limited to toxicants, but also include repellents, attractants and growth regulators (1 ) .

Pesticides are nearly ubiquitous in today's world. In agriculture, insecticides, nematicides and herbicides are applied to plants and soil to …

Measures Of Denitrification In Selected South Dakota Semi-Permanent Prairie Pothole Wetlands, Beverly S. Klein

Electronic Theses and Dissertations

Wetlands are an integral part of agricultural systems in the prairie pothole regions of the North Central United States and Canadian Provinces. Little research has been done on denitrification in prairie potholes, and a better understanding of their denitrifying capability could aide in optimizing management practices near pothole areas. Most probable number (MPN) and denitrifying enzyme activity (DEA or Phase I) assays were conducted. Most probable number (MPN) measures were used to give an estimate of dissimilatory nitrate reduction to ammonia (DNRA) and denitrifying populations present in the wetlands. This study involved 3 selected semi-permanent prairie pothole wetlands near Madison, …

Invertebrate Egg And Plant Seed Banks In Natural, Restored, And Drained Wetlands In The Prairie Pothole Region (Usa) And Potential Effects Of Sedimentation On Recolonization Of Hydrophytes And Aquatic Invertebrates, Robert Andrew Gleason

Electronic Theses and Dissertations

Sediment is the major pollutant of wetlands, lakes, rivers, and estuaries in the United States and it poses unique threats to wetlands of the Prairie Pothole Region (PPR). Sediment may impact the success of wetland restorations because burial of invertebrate and plant propagules may impact hatching and germination success, and hence, may hamper successional changes throughout interannual climate cycles. Sedimentation also reduces the pool depth and volume, further exacerbating the recovery of hydrophyte communities in restored wetlands. I evaluated the potential impacts of sedimentation on prairie wetlands from several perspectives. First, I evaluated the effects of sedimentation on loss of …

Waste audit conducted at Cognis Oleochemical (M) (COM) Sdn. Bhd. indicated that the major process-wastes generated by the facility were glycerol residue (GR) from Cognis Rika (M) Sdn. Bhd. (CRM) and wastewater sludge (WWS) from COM …

The Impact Of Fine Sediment On Stream Macroinvertebrates In Urban And Rural Oregon Streams, Raymond S. Hoy

Dissertations and Theses

Urbanization, often characterized by high impervious surface area, can result in excessive inputs of fine sediments into urban streams. Excessive fine sediments can blanket the stream bed filling the interstitial space in the substratum, which may have adverse effects on stream biota. A field survey was conducted in Oregon urban and non-urban basins to investigate the relationship between fine sediments and stream macroinvertebrates. Physical, chemical, and biological data were collected from 59 stream sites in two urban and two rural streams. The stream sites fulfilled a continuous sediment gradient, which ranged from a low of 2% of fine sediment in …

Comparative Performance Of Wastewater Treatment Plants In Three Rubber Glove Manufacturing Plants, Lee Kuan Loh

Student Works (2000-2009)

During the manufacturing of rubber gloves, water is used as wash water at different stages to clean the rubber gloves, thus generating quite a substantial amount of effluent. There are four main sources of effluent. i.e. a) from the glove formers cleaning tank, which collects the acidified water used to clean these formers, b) latex dipping tank, where it collects wash water used to cool the tank during dipping process and the sludge form the tank itself, c) leaching tank, where it collects wash water used to leach out the pollutants from the gloves and lastly d) latex compounding, containing …
