Fisheries Research Contract Report No. 2 - Towards An Assessment Of Natural And Human Use Impacts On The Marine Environment Of The Abrolhos Islands (Phase 1 : Data Consolidation And Scoping - Final Report For Frdc Project 2000/1 66), C. F. Chubb, K. Nardi

Fisheries Research Contract Reports

This project has drawn together existing research data relating to natural and human impacts on the Abrolhos Islands marine habitats. It has surveyed current uses of these habitats and placed anthropogenic impacts within the context of natural perturbations. Through public forum presentation and debate, this work has allowed real issues, not perceptions, to surface and be addressed properly. This was achieved by defining a strategic programme of research through a scientific workshop process involving all community stakeholders. A two volume Fisheries Research Report (WA) summarizes current knowledge and details the workshop proceedings and strategic research plan.

Fluctuations In Chinook Salmon (Oncorhynchus Tshawytscha) Counts At Three Lower Columbia River Spawning Sites, Eric Michael Loomis May 2003

Fluctuations In Chinook Salmon (Oncorhynchus Tshawytscha) Counts At Three Lower Columbia River Spawning Sites, Eric Michael Loomis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Several hypotheses were developed to explore the pronounced increase in Chinook salmon (Oncorhynchus tshawytscha) returning to spawning grounds at the Cowlitz, Kalama, and Lewis Rivers, three tributaries of the lower Columbia River. The study was conducted using data compiled over a ten-year span from 1991-2001. Preliminary indications are that trends in climate are linked to these increases, with the absence of El Niño events and fluctuations in winter precipitation as likely explanations of these phenomena. The unique nature of Chinook life cycles causes them to utilize a variety of habitats that require ideal conditions for maximum survival rates. Correlations between …

Final Report for FRDC Project 2001/061

Pink snapper (Pagrus auratus) is the main commercial and recreational finfish (Kailola et al., 1993) in the Shark Bay region. Pink snapper are distributed along much of the temperate and tropical coasts of Western Australia from east of Esperance on the south coast to north of Shark Bay on the west (Paulin 1990). Previous research using genetics (Johnson et al. 1986), tagging (Moran et al. 2004), and otolith microchemistry (Edmonds et al., 1989, 1999) have shown that pink snapper from the innermost parts of Shark Bay do not mix with the ocean fish

Guiding Growth: A Survey Of Tax Incentives, New England Environmental Finance Center, Muskie School Of Public Service Jan 2003

Guiding Growth: A Survey Of Tax Incentives, New England Environmental Finance Center, Muskie School Of Public Service

Legislation

Current development patterns and increased tax pressures in local municipalities combine to harm both Maine’s natural resources and its quality of life. Previous initiatives such as the implementation of zoning laws did not fully result in the desired outcomes. Zoning laws were often too flexible and often did not resist market and political pressures to change zoning regulations to allow development with possible economic growth. A sound taxation system or fee structure may be the solution to slow down development in natural areas and direct it towards areas appropriate for growth.

To protect Maine’s natural resources more successfully from future …

Avoiding The “Fat” Of The Land: Case Studies Of Agricultural Nutrient Balance, David Weaver, Simon Neville Jan 2003

Avoiding The “Fat” Of The Land: Case Studies Of Agricultural Nutrient Balance, David Weaver, Simon Neville

Journal articles

Let’s start with a simple analogy: if a person eats more than they need, they gain weight. That is: if our feed inputs (kilojoules in) are greater than our outputs (exercise — kilojoules out) then we will gain weight (kilojoules in storage).That’s our fat. If, on the other hand, our feed inputs are less than our outputs, then we will lose weight.And if our inputs are the same as our outputs, our weight will remain constant. In general, the further away you are from an ‘ideal’weight, the greater the health risks. And yes, other aspects of your body management — …

It has established collection trials in five different locations throughout Ireland in order to characterise and quantify WEEE arisings, and to examine outlets for collected WEEE. Overall, during the twelve months of collection at the project locations, more than 450 tonnes of WEEE was collected from the public and recycled. Within the catchments of each facility, collection rates of between 2.1 and 3.5 kg/person/year were achieved during the twelve-month trial period. With further public awareness raising …


General Guidelines For The Establishment & Evaluation Of Invasive Species Early Detection & Rapid Response Systems Jan 2003

General Guidelines For The Establishment & Evaluation Of Invasive Species Early Detection & Rapid Response Systems

National Invasive Species Council

Preventing the introduction of invasive species is the first line of defense against invasions. However, even the best prevention efforts will not stop all invasive species introductions. Early detection and rapid response (ED&RR) efforts increase the likelihood that invasions will be addressed successfully while populations are still localized and population levels are not beyond that which can be contained and eradicated. Once populations are widely established, all that might be possible is the partial mitigation of negative impacts. In addition, the costs associated with ED&RR efforts are typically far less than those of long-term invasive species management programs.

The charge …


Assessment Of Potential Environmental Impacts Of Nature-Based Tours Originating Within Clark County, Nevada, Beth Domowicz Jan 2003

Assessment Of Potential Environmental Impacts Of Nature-Based Tours Originating Within Clark County, Nevada, Beth Domowicz

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this thesis was to assess the potential magnitude of negative environmental damage of nature-based tours originating in Clark County, Nevada. An ordinal ranking system was used for assessment of five variables. These variables were resource use, noise pollution, soil degradation, vegetation degradation, and wildlife disturbance. There were two proposed answers. The first was that as distance increased, negative tour impact would increase. This was not supported, since tours had high impacts for destinations that were close by and far away. The second was that most tours were not causing high damage to the environment. This hypothesis was …


Addressing Off-Site Nutrient Pollution Through Conventional Management Actions: A Modelling Case Study, David Weaver, Simon Neville, David Deeley Jan 2003

Addressing Off-Site Nutrient Pollution Through Conventional Management Actions: A Modelling Case Study, David Weaver, Simon Neville, David Deeley

Conference papers and presentations

The ecology of estuaries on the south coast of Western Australia has been disrupted by increased nutrient and sediment discharge from predominantly rural catchments. Seagrass beds have been replaced by macroalgae, and toxic algal blooms threaten human and animal health, and reduce amenity. A range of conventional management actions are available to reduce nutrient loss at source, and it is important to evaluate possible reductions, and costs, so that limited funds can be targeted to realise the greatest moderation of nutrient loss. A lumped landuse nutrient generation rate model was developed for four catchments (Wilson Inlet, Oyster Harbour, Torbay Inlet …


Historical Changes In Mid-Water Stands Of Common Reed In The Winnebago Pool Lakes, Wisconsin, Anthony O. Gabriel, Leo R. Bodensteiner Dec 2002

Historical Changes In Mid-Water Stands Of Common Reed In The Winnebago Pool Lakes, Wisconsin, Anthony O. Gabriel, Leo R. Bodensteiner

All Faculty Scholarship for the College of the Sciences

Despite the tolerance of common reed grass to environmental extremes, mid-water stands in the Winnebago pool lakes of central Wisconsin appear to be diminishing. Formerly occupying shoreline locations, water level manipulations subsequent to dam construction beginning in the 1850's have isolated reed stands off shore. These stands have persisted but casual observations indicate that stand size has been declining. To address this perception we obtained an approximately decadal series of aerial photographs dating back to 1937 for four stands in Lake Poygan. Annual records were available for 1986–94. Using image analysis software, we determined shape and size metrics. Changes in …


Effect Of Riparian Land Use On The Biotic Integrity Of Fish Assemblages In Black Creek, Chattanooga, Tennessee, Jerri Leigh Phillips Dec 2002

Effect Of Riparian Land Use On The Biotic Integrity Of Fish Assemblages In Black Creek, Chattanooga, Tennessee, Jerri Leigh Phillips

Masters Theses and Doctoral Dissertations

Black Creek is a third-order Ridge and Valley stream (Tennessee River drainage) in Chattanooga, Tennessee. Most ofBlack Creek's watershed is forested (ca. 71% in 1991 ). However, increasing urban development, particularly along the riparian landscapes, could impact the stream's ecological health. I assessed fish assemblages (biotic integrity), water quality, instream habitat, and riparian land-use features at eight sites in Black Creek, May-June 2000. Water quality conditions (temperature, dissolved oxygen, pH, conductivity) were favorable for stream fishes, but some level of habitat degradation (bank erosion, sedimentation, loss of riparian vegetation) was observed at all sites. Electrofishing samples yielded a total of29 …

Pasture Condition Guides For The Pilbara, A L. Payne, A A. Mitchell Oct 2002

Pasture Condition Guides For The Pilbara, A L. Payne, A A. Mitchell

Agriculture reports

These pasture condition guides are relevant to about 192 000 square kilometres of the Pilbara region of Western Australia. The rangeland of the Pilbara can be separated into 12 very broad pasture types. The ‘pasture type’ is not strictly a botanical classification because, in determining such a class of pastoral lands, the perennial plant species that contribute to stock production have an over-riding importance. Even so, each pasture type represents a broad group of similar vegetation associations or ‘site types’ which will have similar management requirements for pastoralism. The aim of this publication is to provide pastoralists with descriptions and …
