Algal Dynamics In A Cypress Stand In The Seasonally Flooded Great Dismal Swamp, Joseph A. Atchue Iii

Biological Sciences Theses & Dissertations

The dynamics of epiphytic algae and phytoplankton were studied at a cypress stand in the Great Dismal Swamp, Virginia. Mean epiphytic algal biomass was 19.9 g m^-2 and mean planktonic biomass was 3.4 g m^-2.Nutrient concentrations in the epiphytic algae and the litter were determined. The algae had mean concentrations of 1.67% and 0.18%. They were found to immobilize as much as 0.5 g N m^-2 and 0.06 g P m^-2. This suggests that the algae are important as nutrient conservers. The phytoplankton were composed primarily of Bacillariophyceae. They exhibited a more or less …

Low Pressure Membrane Separation Process To Remove Heavy Metal Complexes, Dibakar Bhattacharyya, Chin-Shun Cheng

KWRRI Research Reports

The overall objective of this investigation is to establish the rejection behavior of heavy metals in the presence of complexing agents, utilizing negatively charged ultrafiltration membranes. An extensive experimental investigation is conducted with Zn²⁺, Cd²⁺, Cu²⁺, and Cu¹⁺ in the presence of cyanide, ethylenediamine tetraacetic acid, and oxalates, under insignificant concentration polarization condition. The rejection dependence of the heavy metals is found to be a function of feed metal concentration, metal types, complexing agent to metal feed molar ratio, pH and ionic strength. The dependence of rejection behavior of heavy metals and complexing …

Geology Of Lake Mcconaughy Area, Keith County, Nebraska, Roger K. Pabian, Robert F. Diffendal Jr., Frankie Gould

School of Natural Resources: Faculty Publications

Rocks cropping out along the North Platte River valley at Lake McConaughy provide a glimpse into Nebraska's geologic past. Here are excellent exposures of the Ogallala Group, which consists of continental sedimentary rocks deposited during the Miocene epoch of the Tertiary period of geologic time. This group of rocks extends throughout much of Nebraska (see geologic bedrock map on outside back cover) but is overlain in most places by younger stream and wind deposits of Pliocene(?) and Pleistocene age. Easily accessible, the Ogallala outcrops contain locally abundant fossils of seeds, casts of pedotubules, and occasional fossils of vertebrate animals such …

Estimating Water Demand Schedules For Selected Industries In Arkansas, Joseph A. Ziegler, Stephen E. Bell

Technical Reports

Water demand functions for the paper and chemical industries in the state of Arkansas were estimated utilizing data collected from individual plants throughout the state. Regression analysis was used to estimate demand functions from a data base which included information on intake and gross water use by source, recirculated water use, costs of acquiring, treating, and discharging water, plant output, employment, and level of technology. The demand for intake water was estimated as an exponential function of average water costs and the level of technology primarily. Price elasticities of demand were estimated as approximately equal to one for both industries. …

A Faunal Analysis Of The Springs Of The Ouachita Mountains, Arkansas, Henry W. Robison

Technical Reports

Spring ecosystems in Arkansas have historically received little attention. A faunal survey was made of 33 springs located in the core area Ouachita Mountains physiographic province. The study area was 135 x 80 km extending west from Hot Springs, Arkansas to the Oklahoma line. Springs in the Ouachita Mountain physiographic province were characterized as generally faunistically poor with often a single species such as the isopod, Lirceus h. hoppinae, being the dominant faunal element both numerically and with regard to biomass. A total of 40 species of invertebrate species and eight vertebrate species were collected from the spring environs during …

Classification And Ranking Of Selectd Arkansas Lakes, Robert E. Babcock, Eugene H. Schmitz, Thomas Buchanan, Richard L. Meyer, James I. Meinecke, David B. Czarnecki

Technical Reports

Trophic-state related problems associated with waters in the United States have generated tremendous public interest and concern, particularly during the past decade. These interests and concerns led to Public Law 92-500, the mandate by Congress known as the Federal Water Pollution Control Act. Various sections of PL 92-500 directly address the need for trophic-state analyses, particularly Section 314 referred to as the Clean Lakes Program which assigns states the responsibility for classifying their lakes according to water quality, identifying methods of pollution control and restoring those lakes which have become degraded.

Application Of A New Method For Quantitative Evaluation Of Stream Benthic Algal Populations, Richard L. Meyer, Neil Woomer

Technical Reports

The response of stream biota to changing water quality or other ecosystem perturbations is an important means of assessing water quality. The dynamic nature of streams induces significant sampling and measurement problems. In smaller streams a true algal plankton subcommunity is lacking and the major location for the production of algae is attachment onto stones and other stable surfaces at the substrate-water interface. Several artificial techniques have been developed to analyze the composition of a portion of the epiphytic periphyton (algae attached to stones) but not populations which are qualitatively and quantitatively similar to natural substrates. A newly developed substrate …

A Test Of Macroevolutionary Problems With Neontological Data, Cliff A. Lemen, Patricia W. Freeman

School of Natural Resources: Faculty Publications

Ricklefs (1980) suggested the use of neontological data to distinguish between puncuated equilibrium and gradualism as modes of evolution. This paper investigates his model and finds it contains oversimplifications that make any test difficult. We modify his model slightly and use it as a limited test of punctuated equilibrium by large morphological shifts at speciation. This test is applied to a data set of 110 species from two families of bats, the Emballonuridae and the Molossidae. We find no evidence of consistently large morphological shifts at the formation of subspecies, species or genera.

Water Quality Considerations In The Slurry Pipelining Of Coal, James W. Moore

Technical Reports

Interest in the use of slurry pipelines for the movement of large volumes of coal over long distances has increased rapidly during the last decade. In the early 1970's, this interest involved the movement of Western coals to markets in the southwestern and western United States. In recent years, however, interest in the use of slurry pipelines for transporting Eastern coal developed. Very little information was available concerning the water quality aspects of the slurry pipelining of Eastern coal. The research program was developed to commence building the data base in this regard. Extensive water quality investigations were conducted using …

Land Degradation In The Fitzroy Valley Of Western Australia, Department Of Agriculture, Western Australia. Rangeland Management Branch

Resource management technical reports

The report reassesses the condition of formerly valuable grazing lands of the Fitzroy River valley frontage lands. It is hoped that the submission will promote discussion on the problems of degenerated pastoral land and increase the resolve of all concerned to take the necessary action for their restoration. The frontage lands flank the major rivers of the area, the Fitzroy, the Margaret and the Meda and their tributaries. The frontage is capable of supporting the best pastures in the Kimberley, but unwise and uncontrolled stocking has profoundly degraded and eroded the most productive parts. There are about 5,800 square kilometres …

A Hydrologic Carbonate Chemistry Model Of Flooded Rice Fields, James A. Ferguson, John T. Gilmour

Technical Reports

Many flooded rice fields in Arkansas are irrigated with subterranean waters saturated or supersaturated with respect to calcium carbonate. Deposition of calcium carbonate from these waters largely occurs near field inlets and in flow areas (1). When sufficient amounts of calcium carbonate accumulate, soil pH rises and zinc deficiency occurs in rice seedlings grown on the affected soil (2). The use of zinc fertilizers has provided a short-term solution to the problem (3), but does not provide a water management alternative which would slow, stop or reverse the localized accumulation of calcium carbonate and concomitant soil pH increase.

Review Of Bartlett, Great Surveys Of The American West, And Schubert, Vanguard Of Expansion: Army Engineers In The Trans-Mississippi West, 1819-1879, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

These two books outline the fascinating history of the exploration of the western United States by United States Army topographers and by civilian natural scientists from 1819 to 1879. These two groups, working either together under Army supervision or separately in military and civilian independent surveys, prepared topographic and geologic maps and natural history studies of most of the territory west of the Mississippi River. These maps and studies provided valuable information to settlers and to commercial and government groups involved in opening the west to development, and dispelled many myths concerning previously unexplored regions. They also helped lead to …

Diagenesis Of Organic Matter In Las Vegas Bay And Bonelli Bay, Lake Mead, James W. Murray, Carolyn J. Jones, Kathy Kuivila, Jeff Sawlan

Publications (WR)

The interstitial water chemistry of the sediments of Las Vegas Bay and Bonelli Bay in Lake Mead has been studied as part of a comprehensive water quality study of those locations. Pore water and solid phase analyses were completed from four stations in Las Vegas Bay and two stations in Bonelli Bay. At both locations the pore water compositions and organic matter diagenesis in the sediments are dominated by sulfate reduction. This major role of sulfate reduction is unusual for lake sediments and reflects the fact that SO₄ is the major anion in the lake water. In addition, gypsum …

Petroleum-Utilizing Bacteria: The Biological Line Defense Against Oil Pollution, Steven W. Sokolowski

Biological Sciences Theses & Dissertations

A silica gel-petroleum (SGP) medium was developed which is reliable, approximately the same cost as that of the corresponding agar-based petroleum medium, and can be made sufficiently firm to use in streaking or the spread-plate technique. Advantages of the medium include: the incorporation of all of the major ions of seawater in accordance with Dittmar's Law (the salinity of which can easily be varied from 0 to 35 parts per thousand); a wide workable pH range (5.5 to 11.6); negligable pH drift(~ 0.2 pH units after 166 days); the elimination of all but negligable amounts of syneresis, the ability to …
