Fisheries Research Contract Report No. 20 - Risk Assessment Of The Record Brook Inter-Basin Water Transfer Scheme To The Aquatic Fauna Of The Donnelly And Warren Rivers, M. De Graaf, D. L. Morgan, S. J. Beatty, C. W. Hugh

Fisheries Research Contract Reports

Report to the Water Corporation of Western Australia

This report describes the fishes and freshwater crayfishes of the Donnelly and Warren River catchments and provides a risk assessment to these fauna of the proposed extraction of water from Record Brook (tributary of the Donnelly River) and subsequent transfer to Scabby Gully Dam (Warren River catchment). The proposed location of the structure in Record Brook is at the gauging station ~1 km upstream from the confluence with the Donnelly River. The project aims to divert peak flows in the winter and spring flow period, transferring around 500 ML each year. The …

Modeling West Antarctic Ice Sheet Growth And Collapse Through The Past Five Million Years, David Pollard, Robert M. Deconto

ANDRILL Research and Publications

The West Antarctic ice sheet (WAIS), with ice volume equivalent to ~5 m of sea level, has long been considered capable of past and future catastrophic collapse. Today, the ice sheet is fringed by vulnerable floating ice shelves that buttress the fast flow of inland ice streams. Grounding lines are several hundred meters below sea level and the bed deepens upstream, raising the prospect of runaway retreat. Projections of future WAIS behavior have been hampered by limited understanding of past variations and their underlying forcing mechanisms. Its variation since the Last Glacial Maximum is best known, with grounding lines advancing …

Evapotranspiration Of Irrigated And Rainfed Maize–Soybean Cropping Systems, Andrew E. Suyker, Shashi Verma

School of Natural Resources: Faculty Publications

We have been making year-round measurements of mass and energy exchange in three cropping systems: (a) irrigated continuous maize, (b) irrigated maize–soybean rotation, and (c) rainfed maize–soybean rotation in eastern Nebraska since 2001. In this paper, we present results on evapotranspiration (ET) of these crops for the first 5 years of our study. Growing season ET in the irrigated and rainfed maize averaged 548 and 482 mm, respectively. In irrigated and rainfed soybean, the average growing season ET was 452 and 431 mm, respectively. On average, the maize ET was higher than the soybean ET by 18% for irrigated crops …

The Occurrence Of Illicit And Therapeutic Pharmaceuticals In Wastewater Effluent And Surface Waters In Nebraska, Shannon L. Bartelt-Hunt, Daniel D. Snow, Teyona Damon, Johnette Shockley, Kyle Hoagland

Nebraska Water Center: Faculty Publications

Passive samplers were used to develop semi-quantitative estimates of pharmaceutical concentrations in receiving waters influenced by wastewater effluent. The occurrence and estimated concentration of twenty illicit and therapeutic pharmaceuticals and metabolites in surface waters influenced by wastewater treatment plant (WWTP) discharge and in wastewater effluents in Nebraska were determined using Polar Organic Chemical Integrative Samplers (POCIS). Samplers were installed in rivers upstream and downstream of treated WWTP discharge at four sites and in a discharge canal at a fifth location. Based on differences in estimated concentrations determined from pharmaceuticals recovered from POCIS, WWTP effluent was found to be a significant …

Vegetation, Environmental Characteristics, And Their Relationships: Variation Within The Annually Flooded Riparian Zones Of The John Day River Basin, Oregon, Samuel J. Hartsfield

Dissertations and Theses

I hypothesized that vegetation and physical environmental characteristics would differ between the upper and lower extents of the annually flooded riparian zone on the John Day River, and that relationships between species and environmental variables would display differences between these two zones. Vegetation, environmental variables, and relationships between them were assessed for the entire annually flooded riparian zone, and for the proposed upper and lower zones. Data were collected from 60 one-square-meter quadrats: 30 in each the upper and lower zones. Sites were randomly selected and located so that flood duration was roughly equal at all sites within each zone. …

The Functions And Values Of Fringing Salt Marshes In Northern New England, Usa, Pamela A. Morgan, David M. Burdick, Frederick T. Short

Environmental Studies Faculty Publications

Although large salt marshes of the northeastern United States have been studied extensively, very little is known about the smaller, fringing marshes in this area, despite the fact that they are a common habitat type. We compared the functions and values of five fringing salt marshes (FM) to those of five meadow marshes (MM) along the southern Maine/New Hampshire coast. Specifically we compared their primary production, soil organic matter content, plant diversity, sediment trapping ability and wave dampening properties. Also explored were the relationships between these functions and several physical characteristics at each site, including soil salinity, percent surface slope, …

Methods To Quantify Variable Importance: Implications For Theanalysis Of Noisy Ecological Data, Kim Murray, Mary M. Conner

Wildland Resources Faculty Publications

Determining the importance of independent variables is of practical relevance to ecologists and managers concerned with allocating limited resources to the management of natural systems. Although techniques that identify explanatory variables having the largest influence on the response variable are needed to design management actions effectively, the use of various indices to evaluate variable importance is poorly understood. Using Monte Carlo simulations, we compared six different indices commonly used to evaluate variable importance; zero-order correlations, partial correlations, semipartial correlations, standardized regression coefficients, Akaike weights, and independent effects. We simulated four scenarios to evaluate the indices under progressively more complex circumstances …

Fisheries Research Report No. 188 - Results Of The 2007 Survey Of The Albany Marine Area For Introduced Marine Species, Justin I. Mcdonald, Fred E. Wells, Michael J. Travers

Fisheries Research Reports

A survey of the Albany marine area (King George Sound, Princess Royal Harbour and Oyster Harbour) for introduced marine pest species was conducted in 2007. This survey was trialling the new system of monitoring for introduced marine pests developed by the National Introduced Marine Pests Coordination Group (NIMPCG). This study represents one of the first trials of this system (the first trial commenced in South Australia is still ongoing). In this survey fifty-two of the fifty-five potential pest species were targeted. Three species were excluded on the basis of salinity and/or temperature tolerances being exceeded. A wide variety of sampling …

Fisheries Research Report No. 183 - Development Of A Long-Term Program To Monitor Coastal Communities Within The Swan Region, Lynda M. Bellchambers

Fisheries Research Reports

Marine benthic communities along the metropolitan coast of Western Australia are varied and unique. The southward flowing Leeuwin Current brings warm water and tropical recruits whilst the cooler counter current, the Capes Current, brings the temperate recruits. The result is a mosaic of tropical species intermingled with the dominant temperate species. These areas sustain varied fish and invertebrate communities making this coast a highly desirable location for recreational and commercial use. Management strategies are in place that attempt to maintain the sustainability of this area including various fishery restrictions and the implementation of areas zoned as sanctuary zones (no-take). However, …

Fisheries Research Report No. 185 - Performance Indicators, Biological Reference Points And Decision Rules For Western Australian Abalone Fisheries (Haliotis Sp.): (1) Standardised Catch Per Unit Effort, Anthony M. Hart, Frank Fabris, Nick Caputi

Fisheries Research Reports

This report summarises the performance indicators (PIs) and biological reference points (BRPs) developed from standardised catch per unit effort (SCPUE) models of the Western Australian abalone fisheries. It also outlines analysis and consultation processes used to construct these indicators. Other PIs, such as those relating to harvest rate and recruitment, will be developed when more fishery independent data becomes available.

A comprehensive 7-step process was utilised to develop PIs.

1) The Abalone Management and Advisory Committee (AbMac) considered options and advised that in the short-term, catch and effort trends be reviewed with other potential indicators to be considered at a …

Northern Fur Seal Rookery Photo Archive: Aerial And Ground-Level Photos, Pribilof Islands, Alaska, 1895 - 2006, Kymberly M. Yano, Jessica Y. Tingg, Charles W. Fowler

United States Department of Commerce: Staff Publications

The northern fur seal (Callorhinus ursinus) has been the subject of recorded history for more than two centuries (Scheffer et al. 1984, Scott et al. 2006). It has a long history of being commercially harvested for its valuable pelts (Roppel 1984). Recently, however, fur seals are being seen as one of many species reflecting the conditions of their environment, especially an environment increasingly altered by human influence. The Pribilof Islands fur seal population is currently listed as depleted under terms of the U.S. Marine Mammal Protection Act owing to numbers greatly reduced from those observed historically (National Marine …

Tree Canopy Types Constrain Plant Distributions In Ponderosa Pine- Gambel Oak Forests, Northern Arizona, Scott R. Abella

Public Policy and Leadership Faculty Research

Trees in many forests affect the soils and plants below their canopies. In current high-density southwestern ponderosa pine (Pinus ponderosa) forests, managers have opportunities to enhance multiple ecosystem values by manipulating tree density, distribution, and canopy cover through tree thinning. I performed a study in northern Arizona ponderosa pine-Gambel oak (Quercus gambelii) forests to measure the influences of tree canopy types on understory plant communities and soil properties. On ten 2.5-acre (1-ha) sites, I sampled five 43-ft2 (4-m2) plots below each of the following five canopy types: openings; single ponderosa pine; and Gambel oak single stems, dispersed clumps, and thickets. …

Sustainable Site Remediation : A Life Cycle Assessment Approach, Harnoor Dhaliwal

Theses

Remediation of contaminated areas is often a resource-intensive activity that itself can create environmental burdens. Life cycle assessment (LCA) was used as a tool to examine the environmental impacts associated with remediation activities. A hypothetical contaminated site with five remediation alternatives was developed for this analysis. The results of Life cycle Impact Assessment (LCIA) indicated that greater site activity in terms of transportation, material and equipment use translated into higher environmental impacts.

A sensitivity analysis was performed to evaluate the environmental impacts further in different time horizons. The results showed that choice of time horizon can have a significant effect …

The Role Of Water And Other Resources In The Invasion Of Rubus Armeniacus In Pacific Northwest Ecosystems, Joshua Sundance Caplan

Dissertations and Theses

The factors influencing the invasive success of Rubus armeniacus (Himalayan blackberry) in the Pacific Northwest of North America are only partly understood, but have important implications for its management and for our understanding of the processes driving invasive plant proliferation in regions with seasonally fluctuating resources. I identified patterns of R. armeniacus occurrence and growth under widely ranging soil and light conditions in western Oregon. I found that light availability was a primary determinant of R. armeniacus occurrence and growth. I also found that R. armeniacus was tolerant of a wide range of soil conditions, notably coarse texture, and could …

Evaluation Of Biofuel Driven Irrigation Pumps And/Or Electric Generators For Use During Peak Electricity Demand, Milford Hanna

Nebraska Center for Energy Sciences Research: White Papers and Presentations

The goal of this research is to support the development of a biofuel power unit industry in Nebraska to increase the use of agricultural resources, crops and the resulting biofuels that are produced in the region. Two Nebraska companies developed commercially available technologies to utilize denatured ethanol and other biofuels in industrial power‐units. The successful validation and demonstration of these technologies will support adaptation in water pumping and electrical generation plant applications. It will also document exhaust emissions and compare operating cost with traditional engines and fuels. These technologies could reduce peak load electrical energy demand resulting from electrical powered …

Water, Energy And Agriculture Initiative

Nebraska Center for Energy Sciences Research: White Papers and Presentations

Rapid expansion of the biofuel industry provides exciting opportunities for economic growth and development in rural Nebraska. Realizing the full benefits of this opportunity and ensuring its long‐term viability depends on continued access to adequate supplies of water, electrical energy, and biofuel feedstock crops at reasonable cost. For example, about 70 percent of all corn and 50 percent of soybeans produced in Nebraska comes from irrigated land, and electrical energy for pumping irrigation water represents a major component of peak‐load energy demand in the state. Reducing this peak‐load electrical demand and consumption is essential for reducing the need for new …

Optimization Of Irrigation Efficiency Of Center‐Pivot Systems Using Spatial And Temporal Data Integration, Viacheslav Adamchuk

Nebraska Center for Energy Sciences Research: White Papers and Presentations

The efficiency of a center pivot irrigation system is greatly dependent on the ability to provide the water supply needed to meet the demands of the rowing crop. While limited water supplies may educe crop yield due to water stress, excessive irrigation may result in wasted resources and, if extreme, may also reduce yields. The optimized need for irrigation water changes temporally and spatially. Various methods have been deployed to focus on either level of variability. Thus, soil sensor telemetry and crop modeling frequently allow improved irrigation scheduling. On the other hand, dense‐resolution proximal soil sensing allows identifying spatial variability …

Improvements In Life Cycle Energy Efficiency And Greenhouse Gas Emissions Of Corn-Ethanol, Adam J. Liska, Haishun S. Yang, Virgil R. Bremer, Terry J. Klopfenstein, Daniel T. Walters, Galen Erickson, Kenneth G. Cassman

Nebraska Center for Energy Sciences Research: Publications

Abstract
Corn-ethanol production is expanding rapidly with the adoption of improved technologies to increase energy efficiency and profitability in crop production, ethanol conversion, and coproduct use. Life cycle assessment can evaluate the impact of these changes on environmental performance metrics. To this end, we analyzed the life cycles of corn-ethanol systems accounting for the majority of U.S. capacity to estimate greenhouse gas (GHG) emissions and energy efficiencies on the basis of updated values for crop management and yields, biorefinery operation, and coproduct utilization. Direct-effect GHG emissions were estimated to be equivalent to a 48% to 59% reduction compared to gasoline, …

Studies Of Dna Hybridization Reactions And Applications In Genetic Assays, Fidelis Manyanga

Dissertations and Theses

The intent of this study was to investigate two fundamental aspects of short DNA duplex stability and how that stability differs for duplex molecules consisting of either all perfect match Watson/Crick base pairs or a mixture of perfect match Watson/Crick base pairs and mismatch base pairs. Theoretical and experimental investigations of the origins of the nucleation term in the free energy of DNA duplex formation were revisited. Thermodynamic parameters (ΔG, ΔH, Δ S and Tm) of short DNA/DNA duplexes ranging in length from 6 to 35 base pairs were systematically evaluated by Differential Scanning Calorimetry …
