Factors Affecting Anion Movement And Retention In Four Forest Soils, D. W. Johnson, D. W. Cole, H. Van Miegroet, F. W. Horng

Watershed Sciences Faculty Publications

Three hypotheses concerning the movement and retention of anions in forest soils were tested in a series of laboratory and field studies on two Tennessee Ultisols with mixed deciduous forest cover and two Washington Inceptisols, one with deciduous (red alder Alnus rubra Bong.) and one with coniferous [Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco] forest cover. The first hypothesis, that sulfate and phosphate retention was related to adsorption to free Fe and Al oxides, which were in turn related to soil parent material and degree of weathering, was not supported by results of laboratory and field studies. The young, relatively unweathered Washington …

The Role Of Citizen Participation In Siting A High-Level Radioactive Waste Disposal Facility, Barbara J. Johnson

Journal of the Minnesota Academy of Science

In order to have a successful radioactive waste management and disposal program, the federal government must build public confidence and trust in the siting process (1). To do this three requirements must be met: 1) the program must be technically feasible; 2) the program must be politically palatable; and 3) the program must be societally acceptable.

Citizen participation is necessary to ensure that a radioactive waste management program is accepted by society and is politically feasible. Citizen involvement indirectly impacts technical feasibility by addressing the ethical and moral implications of nuclear waste disposal, thus helping to establish the parameters of …

Penetrating Ionizing Radiation Levels Observed In The Lower Arkansas And White River Valleys Of Arkansas, C. E. Epperson, S. Meiners, D. Swindle

Journal of the Arkansas Academy of Science

Environmental levels of penetrating ionizing radiation were measured in the lower Arkansas and White River valleys of Arkansas. Measurements of environmental gamma and cosmic rays were made using a portable high pressure ionization chamber. The surveyed area encompassed a large coal-fired industrial plant. Observed exposure rates ranged from 5.9 microRoentgens per hour (μR/h) to 13.4 μR/h. The average exposure rate for the region was 8.8 μR/h. This value corresponds to 77 millirem (mrem) or 0.77 milliSieverts (mSv) per year. In comparison, a prior state-wide survey reported an average dose equivalent rate of 78.2 mrem (0.782 mSv) per year in Arkansas.

Analysis Of The Charleston, Illinois Water Supply For The Presence Of Organic Mutagens Utilizing The Ames Salmonella/Microsome Assay, Steven Lee Washburn

Masters Theses

Water samples from the Charleston, Illinois water supply and selected agricultural run-off areas were tested for the presence of organic mutagenic chemicals. The Ames Salmonella/microsome mutagenicity assay utilizing strains TA98 and TA100 was used to analyze concentrated water samples. A special set of samples was exposed to the S9 activation system coupled with the TA98 strain to simulate the mammalian metabolic system.

No mutagens were detected in any of the samples tested. Several positive and negative control systems were included in the testing system. Negative control systems were used to determine the average spontaneous reversion rates for each strain for …

Water Quality Management Studies For Water Resources Development In The Bear River Basin, Darwin L. Sorensen, Craig Caupp, William J. Grenney, Steve Eberl, Jay J. Messer, Phillip Ludvigsen, Charles W. Ariss

Reports

Summary: The quality of water that develops in the proposed reservoirs of the Upper Bear River Storage Project will determine the possible uses of the water. Previous studies of water quality in the Bear River and its tributaries have reported water quality problems relating to nitrate ion, sanitary indicator bacteria, suspended solids, and phosphorus concentrations. Most point sources of water pollution inthe basin have been eliminated or improved in quality, but nonpoint sources of pollution continue to degrade the quality of the Bear River. Concentrations of phosphours have been sufficiently high to encourage dense algal growth and create eutrophic conditions …

Economic Evaluation Of Conservation Concepts For Municipal Water Systems, Trevor C. Hughes, Rangesan Narayanan, Mac Mckee, A. Bruce Bishop, Robert Leconte, Sumani Al-Hassan

Reports

Five concepts for conservation of municipal water supply are analyzed from an economic efficiency perspectice. They include: 1) seasonal pricing (for reduction of peak period water use), 2) dual water systems (separate high quality drinking water and untreated outdoor irrigation systems), 3) imported water transmission facility capacity optimization, 4) flow restricting devices, and 5) short-term rationing concepts. Optimization models, including generalized model generators, were developed for analysis of the first three concepts and demonstrated by applications to cities in Utah. The flow restricting device and short-term rationsing concept analyses applied approaches taken from the literature to example sites in Utah. …

What Quality Management in Utah Mountain Streams: Several years of thorough monitoring of water quality parameters in Little Cottonwood Creek in Salt Lake County, Utah, measured the natural levels of the major water constituents, spotted significant (largely nonpoint) pollution sources, identified the pollutants deserving primary attention, and suggested the approaches to land and water management for pollution control in a mountain watershed used primarily for recreation purposes. Bacterial pollution is greater at night than during the day, on weekends than on week days, and in the summer than in the winter. Mineral content is of natural origin and largely explained …

Expected Effects Of In-Lake Dikes On Water Levels And Quality In The Farmington Bay And The East Shore Areas Of The Great Salt Lake, Utah (Executive Summary), Duane G. Chadwick, J. Paul Riley, Alberta J. Seierstad, Darwin L. Sorensen, Norman E. Stauffer

Reports

Introduction: The Great Salt Lake is a terminal lake and as such is one of the major inland bodies of salt water in the world, and the largest lake of brine in the western hemisphere. Its unique features, including its mineral rich waters and interesting shores and islands, make it appealing to both industry and vacationers. Until recently, some of the great waterfowl sanctuaries in the U.S. existed along the easterly and northerly shores of the lake. However, during the past three years record breaking inflow volumes and lower than normal evaporation rates have caused an unprecidented rate of rise …

Incidence And Significance Of Giardia Lamblia (Lambl ) In Texas Beaver Populations, Robert Beach, William F. Mcculloch

Great Plains Wildlife Damage Control Workshop Proceedings

The Giardia lamblia (Lambl) protozoan is not a recently discovered parasite. It was. in fact, one of the first organisms viewed and described by Antony van Leeuwenhoek (1681) as he designed the first usable microscope. Leeuwenhoek found this organism in a sample of his own diarrhetic stool and thus he constitutes the first confirmed case of human giardiasis. His finding represents proof of glardiasis’ close association with man for many years. Leeuwenhoek’s discovery of the giardial trophozoite was not elaborated on for some 178 years, however, as it was not until 1859 that Wilhelm D. Lambl systematically described the organism …

The Use Of Fixed Wing Aircraft In Predator Control, Larry D. Vetterman

Great Plains Wildlife Damage Control Workshop Proceedings

Aerial hunting was first used in a professional predator control program in 1942. The most popular aircraft used by animal damage control agencies is the Piper PA-18. Proper training of flight crews is of utmost importance for a successful aerial operation. Fixed wing hunting is restricted to relatively open areas and flat terrain. Aerial hunting is an excellent control method where livestock losses are severe and immediate control is needed.

Preliminary Studies On The Feasibility Of Urban Rabies Control, Richard C. Rosatte

Great Plains Wildlife Damage Control Workshop Proceedings

A preliminary investigation was initiated in 1984 to determine the feasibility of an urban rabies control strategy which involved capturing, vaccinating and releasing skunks and raccoons in metropolitan Toronto, Ontario. Results indicate urban skunks and raccoons are utilizing extremely small home ranges and their movements are not extensive. Trapping data suggested a large proportion of the population of skunks and raccoons in the study area were captured during the first 4 nights of trapping. Capture data also indicated the presence of new animals in the study areas between trapping periods. The 3 study areas, which differed in human land-use classification, …

Aggressive Behavior Of Mississippi Kites In Suburban Areas, Berkeley R. Peterson, Charles S. Brown

Great Plains Wildlife Damage Control Workshop Proceedings

The Mississippi Kite is a small diurnal bird of prey which nests throughout the southern Great Plains Its aggressive behavior during nesting has created problems for residents in suburban areas. The removal of the nest and relocation of the eggs and young will end the attacks by the parent birds. The eggs are incubated and the resulting young, as well as other young removed from problem nests, are then placed in foster nests in more remote areas. Preliminary results indicated this will be a very successful way of dealing with the young of problem kites and is an effective way …

The Effect Of Dietary Protein And Feed Size On The Assimilation Efficiency Of Starlings And Blackbirds, Daniel J. Twedt

Great Plains Wildlife Damage Control Workshop Proceedings

Starlings (Sturnus vulgarisl were fed 3 feed sizes and 3 protein levels of swine feeds to determine metabolizable energy and assimilation efficiency. Metabolizable energy (12 kcal/g of diet consumed) and assimilation efficiency (3296 of gross energy intake) were independent of feed size. A 46% crude protein diet was 5196 assimilated and yielded more energy per gram of diet consumed than a 2196 crude protein diet which was only 35% assimilated. Starlings failed to maintain their body weight on a cracked corn diet containing 14% crude protein. Feeding behaviors of starlings due to their assimilation efficiencies are discussed and contrasted with …

Alligator Nuisance Control Program In Texas: Problem And Process, Lee Ann Johnson, David S. Lobpries, Bruce G. Thompson

Great Plains Wildlife Damage Control Workshop Proceedings

Following protection of the American alligator (Alligator mississippiensis) in Texas beginning in 1969, alligator numbers have increased rapidly (Patter 1981). Such population increases led to the federal reclassification of the species from Endangered to Threatened--Similarity of Appearance in 1983 in Texas (Bowman 1983). Similarity of appearance classification acknowledges the biological security of the Texas alligator population and the need for specific harvest controls to ensure that the conservation of similar appearing species is not compromised. As alligator populations recovered, nuisance complaints directed to the Texas Parks and Wildlife Department (T'PWD) accelerated as well. Complaints now number several hundred annually and …

Deer Damage Prevention Efforts In Pennsylvania, Jack M. Payee, William L. Palmer

Great Plains Wildlife Damage Control Workshop Proceedings

Research at the Pennsylvania State University was directed towards finding effective repellents to control damage caused by white-tailed deer (Odocoileus virginianus) and to develop a low-cost alternative to the traditional 2.4 m woven wire barrier fence, considered to be deer-proof, but too expensive for mgt agricultural uses. Fourteen repellents were screened and 9 were found to be more effective than the others. These 9 repellents were further investigated under semi-field conditions and only 1 repellent was found to be consistent in reducing deer feeding. A vertical electric deer fence was effective in excluding deer at field sites containing alfalfa, small …
