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

Geology Of Lake Mcconaughy Area, Keith County, Nebraska, Roger K. Pabian, Robert F. Diffendal Jr., Frankie Gould
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 …
Application Of A New Method For Quantitative Evaluation Of Stream Benthic Algal Populations, Richard L. Meyer, Neil Woomer
Application Of A New Method For Quantitative Evaluation Of Stream Benthic Algal Populations, Richard L. Meyer, Neil Woomer
Arkansas Water Resources Center 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 …
Estimating Water Demand Schedules For Selected Industries In Arkansas, Joseph A. Ziegler, Stephen E. Bell
Estimating Water Demand Schedules For Selected Industries In Arkansas, Joseph A. Ziegler, Stephen E. Bell
Arkansas Water Resources Center 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. …

Arkansas Water Resources Center 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.
A Faunal Analysis Of The Springs Of The Ouachita Mountains, Arkansas, Henry W. Robison
A Faunal Analysis Of The Springs Of The Ouachita Mountains, Arkansas, Henry W. Robison
Arkansas Water Resources Center 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 …

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 …

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

Instars And Polymorphism Of Castes In Macrotermes Michaelseni (Isoptera, Macrotermitinae), B. M. Okot-Kotber
All Peer-Reviewed Publications
Biometric studies and physiological investigations made it possible to propose a scheme of post-embryonic development and polymorphism in Macrotermes michaelseni. An instar hitherto undescribed has been found and designated fourth instar. This instar is comprised of female larvae which moult into major presoldiers. Minor presoldiers moult from some of the third instar female larvae which are morphologically identical to the female worker larvae. Three instars were detected in the case of both minor and major worker development. Workers and soldiers are sterile castes. Nymphs develop from first instar larvae and moult through five instars before imaginal moult. © 1981 Masson.

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 …

Water Quality Considerations In The Slurry Pipelining Of Coal, James W. Moore
Water Quality Considerations In The Slurry Pipelining Of Coal, James W. Moore
Arkansas Water Resources Center 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 …

Lithologic And Structural Controls On Karst Landforms Of The Mitchell Plain, Indiana, And Pennyroyal Plateau, Kentucky, Frederick Jennings Woodson
All-Inclusive List of Electronic Theses and Dissertations
Karst features in Harrison County, Indiana, and the Mammoth Cave region, Kentucky, are profoundly influenced by lithology and structure. In the Sinkhole Plain two classes of sinkholes, shallow solutional and deeper subsidence, differ in morphology, origin, age, distribution, and density. Distributions of the two kinds of sinkholes reflect the outcrop pattern of specific lithostratigraphic units. Broad shallow dolines (Ste. Genevieve-type sinks) develop on the Horse Cave Member of the St. Louis Limestone and on the Ste. Genevieve, Girkin, and Paoli Limestones. Innumerable steeper-sided subsidence and collapse depressions (St. Louis-type sinkholes) form on the Corydon Chert Member, lower St. Louis Limestone, …

A Hydrologic Carbonate Chemistry Model Of Flooded Rice Fields, James A. Ferguson, John T. Gilmour
A Hydrologic Carbonate Chemistry Model Of Flooded Rice Fields, James A. Ferguson, John T. Gilmour
Arkansas Water Resources Center 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 …
