Travel Time Study At The Wetlands Park National Preserve, Brandon Bair

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis reports on a study of the residence time of water in the Wetlands Park Nature Preserve in Henderson, Nevada. Rhodamine WT was used in order to test for the travel time of the water from the Monson Channel inflow to the Nature Preserve outflow to the Las Vegas Wash. The initial hypothesis was that the water would stay in the system for approximately 8 days. Residence time was tested using an ISCO sampling machine along with a Sequoia-Turner model 450 fluorimeter to test for the fluoresce of the dye in the water. All samples collected were taken immediately …

West Mortlock Catchment Appraisal 2002, D G. Cummins

Resource management technical reports

This report describes the soils, hydrology, natural vegetation and farming systems of the West Mortlock catchment and provides information on the threats to agriculture, infrastructure and natural resources caused by land degradation. West Mortlock covers over 700,000 hectares in the central wheatbelt.

Water Quality Assessment In Cypress Creek Nature Preserve, Jason Flora

Masters Theses & Specialist Projects

Swamps are unique ecological communities that provide many valuable ecosystem services. In Kentucky, however, many swamps were altered by cypress removal and land development in their watersheds. Cypress Creek Swamp, which lies near Paducah in western Kentucky, is a good example of a swamp whose ecological integrity may be threatened by past and current nearby land use practices. This study was conducted to assess the water quality and macro- and microinvertebrate communities in the swamp. Three sites were monitored for temperature, dissolved oxygen, pH, specific conductivity, depth, phosphorus measured as orthophosphate, nitrite (NO2") and nitrate (NO3", NOx collectively), and ammonia …

It is perhaps the most comprehensive report of its kind in Australia. As this Government moves toward a more integrated approach to the management of fish resources this report is timely, and represents an opportunity to ensure Aboriginal fishing interests are given appropriate recognition in a more holistic approach to ensuring fish stocks are sustained for future generations.

Assessing Storage Reliability Of Farm Dams, D Farmer, N Coles

Resource management technical reports

This report provides information on a method to estimate the volume of water in a farm dam and to determine how long this water will last. During periods of low rainfall, dams with farmland catchments receive limited run-off. Alternative water sources or management strategies need to be considered before the water runs out. The methods provided in this report are intended to provide to the landholder an indication of water supply over short periods only (i.e. in the order of 4-20 weeks).

Mercury Concentrations In Streams Of East Texas, Mingteh Chang, Mark C. Cochran, R. Scott Beasley, Matthew W. Mcbroom

Faculty Publications

Recent studies on potential mercury (Hg) contamination of fish from East Texas lakes and waterways have caused concern about mercury levels in East Texas waters. Historical records of Hg concentrations in 33 East Texas streams showed that median concentrations for each stream segment were no different than other U.S. streams. All the means and medians for stream segments having at least 20 recorded measurements were less than Texas (2.4 µg/L) water quality standards. Water samples collected in December 1995 and March 1996 from 6 different stream sites in Nacogdoches County had concentrations similar to historical records. Due to biological magnification, …

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 …

Determining The Factors That Control Respiration And Carbon Use Efficiency In Crop Plants, Jonathan M. Frantz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the literature on plant respiration, there are two viewpoints concerning the source of respiratory control: supply (photosynthate availability) or demand (temperature dependent) limitations. While different studies indicate the primary dependency for respiration is either the supply or demand side, the two paradigms cannot both be true. The relative importance of each paradigm may depend on a number of factors including period of time during which respiration is measured, phase of plant development, environmental conditions, and species.

Studies were performed using continuous CO₂ gas-exchange instrumentation to monitor short- and long-term changes in whole canopies of lettuce, tomato, soybean, and …

Breeding Bird Communities Of Major Mainland Rivers Of Southeastern Alaska, Jim A. Johnson

Impacts Of Small Mammals And Birds On Low-Tillage, Dryland Crops, Ray T. Sterner, Brett E. Petersen, Stanley E. Gaddis, Kenneth L. Tope, David J. Poss

United States Department of Agriculture Wildlife Services: Staff Publications

During 2000–2001, small mammals, birds, and potential corn/soybean damage were studied at a low-tillage, non-irrigated agricultural research site in the Colorado Piedmont. A small mammal surveyinvolved four trapping sessions and 18, 12-live-trap grids each. Within years, two grids each were placed at random, fixed locations in experimental corn, fallow, millet, pea, soybean, sunflower, and wheat plots at the site; two off-plot grids each were set at random, fixed locations <100m from the north and south edge of these plots. In 2001, periodic bird observations were conducted, and damage to corn and soybean plants was assessed. Capture rates were low during all trap sessions (range 0.1%–3.3%, Χ̅ = 2:2%). Sixty-three small mammals were captured and 39 were recaptured. Captures included deer mouse (Peromyscus maniculatus), northern grasshopper mouse (Onychomys leucogaster), thirteen-lined ground squirrel (Spermophilus tridecemlineatus), and western harvest mouse (Reithrodontomys megalotis). Deer mice accounted for 56 of …

Environmental Science and Geology Faculty Research Publications

The depositional fluxes in the bulk and dry fallout as well as the concentrations of ⁷Be and ²¹⁰Pb in aerosols were measured for a period of 17 months at Detroit, Michigan. The bulk depositional fluxes of ⁷Be and ²¹⁰Pb varied between 3.11 and 63.0 dpm cm⁻² yr⁻¹ (mean of 11.4 dpm cm⁻² yr⁻¹) and 0.35 and 10.3 dpm cm⁻² yr⁻¹ (mean of 1.41 dpm cm⁻² yr⁻¹), respectively, and this variability in the depositional fluxes is attributed to the frequency and amount of precipitation and seasonal variations …

Simazine Mineralization In Wetland Soils Of William's Island, Elise Chapman

Honors Theses

Wetlands are an interface between terrestrial and aquatic environments. As anthropogenic impacts on the environment increase it puts these sensitive areas at the forefront of change. Farming on William's Island has not occurred since 2001 but before that it was farmed to provide cost-free upkeep of the island. Simazine is a triazine herbicide, the most commonly used group of herbicides in modem agricultural practices. The fields on William's Island were most likely exposed because they were farmed for numerous years prior to 2001. Because of this the wetland that drains the fields, separating them from the Tennessee River, may have …
