Life Histories In An Epifaunal Community: Coupling Of Adult And Larval Processes, Brian L. Bingham
Environmental Sciences Faculty and Staff Publications
Marine invertebrates growing epifaunally on red mangrove (Rhizophora mangle) prop roots in the Indian River, Florida, USA, were studied in a small mangrove island (Jim Island) through which a number of channels had been cut. Roots hanging down into the water supported diverse epifaunal communities including sponges, oysters, barnacles, bryozoans, and ascidians. To determine what factors control species' population dynamics and contribute to the high degree of spatial heterogeneity characteristic of communities in this unique habitat, two hypotheses were tested: (1) Distributions of species on the roots are controlled by differential growth and mortality due to physical features; and (2) …

Ground Water Flow And Water Resources Investigation Of The Auburn, Summers And Shakertown Springs Karst Ground Water Basins, Logan And Simpson Counties, Kentucky, William Howcroft
Masters Theses & Specialist Projects
The City of Auburn is faced with a number of problems relating to its dependency on two karst springs, Auburn and Summers Springs, to meet its water requirements. Besides being extremely vulnerable to contamination, the springs often discharge and insufficient volume of water needed for public consumption and dilution of the City’s treated wastewater. Thus the City wishes to find an additional source of water and views nearby Shakertown Spring as a possibility. The study has three main objectives: 1) delineation of the Auburn, Summers, and Shakertown Springs ground water basins, 2) determination of the volume of available water at …

Concerns have been raised over the potential impacts of the Animas/LaPlata project and the regulation of Navajo Dam. Flow depletions in the San Juan River may adversely affect the remnant population of the native fish, particularly the endangered Colorado squawfish and the razorback sucker. A multiyear research program is currently being conducted on the San Juan River as a result of a Jeopardy Opinion delivered by the U.S. Fish and Wildlife Service on Animas/LaPlata and the subsequent Reasonable and Prudent Alternative that was accepted. A mulidisciplinary research team composed of representatives from the affected agencies is currently investigating the relationship …

Publications (WR)
Throughout North America there is a growing interest in constructed wetlands, both as relatively inexpensive, low-maintenance systems for removing nutrients from wastewater, and as a means of using municipal wastewater to enhance wildlife habitat and create public use opportunities. Because wetlands appear to have good potential as a component in the overall management of scarce water resources, the Bureau of Reclamation (Reclamation) has undertaken several cooperative research and demonstration projects to evaluate their effectiveness in a variety of local environments.
While a number of projects have demonstrated that wetlands can be beneficially employed to improve water quality, few such projects …

Status Of The Public Oyster Resource Of Virginia - Fall 1992, Bruce J. Barber
Reports
oysters have been harvested from Virginia waters as long as humans have i):'lhabited the area. Depletion of natural stocks in the late 1880's led to the establishment of regulations by public fisheries agencies. A survey of bottom areas in which oysters grew naturally was completed in 1896 under the direction of Lt. Baylor, USN. These areas (over 243,000 acres) were set aside by legislative action for public use and have come to be known as the Baylor survey Grounds or Public oyster Grounds of Virginia, and are presently administered by the Virginia Marine Resources commission (VMRC). Twice a year the …

Arkansas Agricultural Chemical Ground-Water Management Plan, Gerald King, Darryl Little, Tim Jessup, Charles Armstrong
Technical Reports
The Arkansas Agricultural Chemical Ground-Water Management Plan (SMP) is based on the Draft State Pesticide Ground- Water Management Plan Guidance and The Pesticides and Ground-Water Protection Strategy prepared by the U.S. Environmental Protection Agency (EPA). The need for a plan to protect ground water from contamination by agricultural chemicals and agents arises from evidence nationwide that using these chemicals can, in some instances, lead to contamination. In February 1988, EPA proposed a strategy to regulate certain pesticides by prohibiting their use in areas vulnerable to leaching unless a state develops and implements an acceptable management plan. The advantage of a …

Use Of High-Energy Radiation For Degradation Of Environmental Pollutants, Robert D. Guthrie, Manjiri Patwardhan
Use Of High-Energy Radiation For Degradation Of Environmental Pollutants, Robert D. Guthrie, Manjiri Patwardhan
KWRRI Research Reports
The purpose of this project was to explore the advantages and/or limitations of high-energy radiation treatment as a method for degrading organic pollutants, particularly aryl halides, in an aqueous medium. We have done analyses of 60Co-irradiated samples and kinetic studies using pulsed electron beams. For aryl halides containing no more than two fused rings, the main products detected are those of simple halogen replacement by hydrogen, although the amount of aryl halide destroyed was always greater than the total amount of products detected. To accomplish halogen replacement by H, the reaction solvent may not be pure water but must …

A Three-Dimensional Circulation Model For Tampa Bay, Y. P. Sheng, J. K. Choi, S. B. Malakar, S. L. Schofield, D. Welter, E. Yassuda
Reports
Y. Peter Sheng, the Principal Investigator of the proposed study, has developed and applied three-dimensional hydrodynamic models since 1972. These models were developed for a variety of water bodies (including estuaries, lakes, and coastal waters) for a variety of government agencies (e.g., USEPA, USGS, SBNEP, USAE, SFWMD, and SJRWMD) and petroleum companies (Standard Oil and Mobil) to solve a variety of problems. Basically, the nature of the problem and the water body determines the purpose of the modeling study and hence the features and capabilities of the model.

Field Calibration Of A Transient Model For Broiler Misting, Richard S. Gates, Douglas G. Overhults, Robert W. Bottcher, Shu Hui Zhang
Biosystems and Agricultural Engineering Faculty Publications
A transient model to predict temperature within a tunnel ventilated broiler house during misting is developed. The model is calibrated with field data to obtain steady-state constants; transient predictions are compared to measured temperatures during cyclic misting for two different size birds. Measured temperatures during cyclic misting are shown to swing between steady-state asymptotes predicted from the model. Transient response of the model was faster than measured temperature data, in part due to temperature sensor dynamic response. The model predicts the length-wise temperature profile within the building during misting, and can be used to investigate alternate misting strategies and designs. …

Relationship Between Ground And Surface Water Quality In Karst Systems, Richard L. Meyer
Relationship Between Ground And Surface Water Quality In Karst Systems, Richard L. Meyer
Technical Reports
Springs in Northwest Arkansas may originate from relatively small fractures in rock strata or from cave systems. The water emerging from these springs is frequently used as water sources for plants, animals and humans. The quality of the ground water source and the emerging water are uncertain and frequently unknown. In addition, the opportunity to monitor changes in water quality during flow from origin (water entering the cave) to emergence is uncommon. Cave systems with definable drainage basins and accessible sampling points near the midpoint of the cave are also uncommon. Examining the interface between the quality of surface water …

Dissolved Oxygen Measurements In The Machipongo River System Near Willis Wharf, Virginia, Bruce Neilson, Cheol Mo, Rodney Jackson
Reports
Most aquatic organisms require· oxygen to survive and consequently, the dissolved oxygen (DO) content of the water is one of the most important measures of water quality. Sources of oxygen are the atmosphere and photosynthesis. Oxygen is consumed by plants and animals during respiration and by microorganisms that decompose organic matter. The more sources and sinks of oxygen, the more difficult it is to understand and predict the oxygen dynamics of a river system. Grossly polluted systems turn out to be quite simple, because the pollutant source dominates. Natural, unimpacted systems often show a balance between a number of sources …

Morphometrics Of The Family Emballonuridae, Patricia W. Freeman, Cliff A. Lemen
School of Natural Resources: Faculty Publications
Morphometric analysis revealed three distinctive groups among the genera of emballonurids. Taphozous-Saccolaimus is a group distinctive in size and shape, particularly cranially. Diclidurids are distinctive in appendicular characters only, especially those in the wing. The third group include all other emballonurids. Phylogenetic studies also separated Taphozous-Saccolaimus as distinctive but included diclidurids among other New World species. Compared with molossids, emballonurids are morphometrically quite homogeneous.
