New Concepts For Preliminary Hydropower Design: The Powermax Slope, Binary Turbine Sizing, And Static Regain, Frank W. Haws, Eugene K. Israelsen

Reports

In Utah during the 1960s, the cost of producing electrical energy was as much, or in some cases more, by hydroelectric generation than by plants using steam from coal fired boilers. The relatively high hydropower cost was generally attributed to maintenance and replacement costs associated with plants that had been build in the 1920s. Utah Power & Light Company during the 1960 period decided not to renew power licenses and to abandon many small hdyroplants. Since 1973, rising coal and related fossil fuel costs have caused steam generation costs to accelerate and have made hydroelectric generation relatively more attractive. However, …

Vegetation Changes In Four Study Areas At Indiana Dunes National Lakeshore, Kathryn Ann Kerr

Masters Theses

The sampling transects at Indiana Dunes were established to show the pre-burn condition of the vetetation and to monitor the long term effects of burning. However, one year of monitoring showed changes in vetetation that further substantiate the need for the burning program.

Miller Woods (Transect A) has burned frequently in recent years. The one year without fire showed little change in the herbaceous layer. The few notable herbaceous changes might indicate a transition to a more mesic community, but should be viewed skeptically because of the wet season in 1982.

Nearly half of the small shrub species at Miller …

Sediment Oxygen Demand In Streams Receiving Sewage Effluent, John J. Schultz

Masters Theses

Sediment oxygen demand is an important factor in determining dissolved oxygen concentrations in streams and rivers subjected to sewage effluents and other sources of organic pollution. Resuspension of sediments during bottom-scouring after periods of heavy precipitation exerts an immediate and increased oxygen demand on the water and is expected to decrease sediment oxygen demand at the site.

Sediment samples were collected monthly from April through November, 1983 from three small streams subjected to sources of organic pollution. The samples collected were arbitrarily categorized into wet and dry period samples based on the total precipitation between collection dates. Sediment oxygen demand …

Resin Acid Compounds In A Kraft Pulp And Paper Mill Effluent And Their Distribution In Bottom Sediments Near The Outfall, Manida Unkulvasapaul

Dissertations, Theses, and Masters Projects

Kraft pulp and paper mill effluents (KPPME) collected on three occasions were analyzed for resin acids, aliphatic hydrocarbons, and aromatic hydrocarbons. The maximum total concentrations of these compounds found in secondary effluents were 8 mg/L resin acids, 4.0 mg/L resolved aliphatic hydrocarbons, and 0.2 mg/L resolved aromatic hydrocarbons. Abietic acid and dehydroabietic acid were the two major components in resin acid fractions and were responsible for > 70% of the total concentration. Analyses of estuarine water and sediments collected from the outfall and nearby areas showed that dehydroabietic acid was the major resin acid in either water or sediment. Concentrations of …

Applications Of Aerial Imagery In Identification Of Natural Areas, Kendall Duane Wessel

Dissertations and Theses @ UNI

There is current interest in utilizing aerial imagery to obtain information on natural vegetation. The purpose of this study is to utilize and evaluate commonly available aerial imagery to identify potential natural areas suitable for preservation and to initiate development of a procedure for imagery interpretation to meet this goal.

Clayton County, located in the northeastern quarter of the state of Iowa, was selected for study because it is dissected by steep, narrow stream valleys that are unsuitable for cultivation and may still possess native vegetation of a quality suitable for preservation.

Baseline or control communities were selected from known …

Fencing For Deer Control, William R. Bonwell

Great Plains Wildlife Damage Control Workshop Proceedings

Deer (odocoileus virginianus) depredations are a serious problem for many landowners and few landowners plan for these potential depredations. Fencing to restrict deer movements has become the most economical means of control. Several fence designs are available but the new electrified high tensile wire fences hold the most promise for deer control.

Rodent-Agriculture Interactions In No-Tillage Crop Fields, Kent E. Holm, Ron J. Johnson, Walter W. Stroup

Great Plains Wildlife Damage Control Workshop Proceedings

Acreage in reduced- and no-tillage farming systems has increased markedly in recent years, a trend that is expected to continue. However, small rodent populations thrive in these fields and at times dig and consume newly planted seeds and seedlings. During 1983, no-tillage corn, wheat and grain sorghum fields in western (Red Willow Co.) and eastern (Saline and Jefferson Cos.) Nebraska were evaluated to determine the distribution and food habits of the rodent species present, the damage to crops, and the availability of alternate rodent food sources. During June (post-emergence) and August (maximum corn height), 676 rodents were captured in 11 …

Some International Approaches To Rat Control, Walter E. Howard

Great Plains Wildlife Damage Control Workshop Proceedings

There are many basic requirements concerning the political structure, financial support needed, proper organization, staff training, public education, laws and regulations, and the keeping of good records, which must be adequately considered before a rat control program can become successful. Likewise, there are also a number of basic principles concerning rodent control that must be understood and adhered to. Some villages in Korea and the country of Kuwait will be used as examples of new rat control approaches.

Workshop-Discussion Session, Joesph M. Schaefer

Great Plains Wildlife Damage Control Workshop Proceedings

The purpose of the workshop-discussion session was to establish a list of ideas that would provide the best focus and direction to improve wildlife damage control programs. During this session the Nominal Group Technique (NGT) (Delbecq et al. 1975) was used to: 1) identify and rank obstacles that limit the effectiveness of wildlife damage control efforts, and 2) generate possible solutions to the most important obstacles. This format allowed equal and full participation and was successful in generating many original ideas.

Behavioral Ecology Of Coyotes: Implications For Reducing Predator-Livestock Conflicts, William F. Andelt

During the past 2 decades, numerous research projects have been conducted to gain a better understanding of coyote (Canis latrans) behavior and ecology which could be used to reduce livestock losses to predators. This paper synthesizes some of these investigations to provide some insight into methods of reducing livestock losses to coyotes.

Rodent Management On The Northern High Plains, Ardell J. Bjugstad

Great Plains Wildlife Damage Control Workshop Proceedings

Rodent damage on the Northern High Plains has caused estimated economic losses of millions of dollars per year. The Columbian ground squirrel (Citellus columbianus) caused $800,000 damage in Montana during 1973, whereas prairie dogs (Cvnomvs ludovicianus) caused a loss of $2 million in South Dakota during 1980. Initial control of prairie dogs in South Dakota would cost approximately $1.2 million dollars and maintenance measures would be needed about every third to fifth year depending on percentage success of the initial control and management practices thereafter. Results of a cost-benefit study in South Dakota indicated that the annual maintenance control rate …

Great Plains Wildlife Damage Control Workshop Proceedings

Gray squirrel (Sciurus carolinensis) damage to roofs is becoming a major concern to homeowners especially with the steadily increasing construction of houses with wood shingles. Besides causing roof damage (rain leaks), electrical wires are often gnawed. The gray squirrel is finding excellent nesting area in attics and overhang voids.

A Decade Of Usda-Ars Predator Research, 1972-1982, Jeffrey S. Green

Great Plains Wildlife Damage Control Workshop Proceedings

Federal government restrictions in 1972 on several widely-used forms of predator control stimulated research on alternative methods of reducing depredation on livestock. In the same year, the U.S. Department of Agriculture began predator research through the Agricultural Research Service (ARS) and designed the U.S. Sheep Experiment Station CUSSES, near Dubois in southeastern Idaho as the principle location for the investigations. At the outset, the objective of ARS research was to examine non-lethal methods for reducing depredation, primarily by coyotes (Cants), on sheep. During the first several years, while predator research facilities were constructed at the USSES, ARS funds were primarily …

Wildlife Damage Control Problems And Concerns Of State Wildlife Agencies, F. Robert Henderson

Great Plains Wildlife Damage Control Workshop Proceedings

Wildlife damage seems to be a greater concern today than 10 years ago. Controlling wildlife damage is a complex issue and the responsibility for its accomplishment has been given to diverse groups of private, local, county, state and federal entities. The types of programs vary from state to state, and often within a state several different programs are conducted by different agencies. It is the purpose of this paper to attempt to present information on the concerns of the state wildlife agencies regarding wildlife damage problems.

Rancher Use Of Compound 1080 Toxic Collars In New Mexico, Gary A. Littauer

Great Plains Wildlife Damage Control Workshop Proceedings

Twenty-three ranchers were trained and certified to use Compound 1080 in toxic collars to control coyote ( Ca nts l a tran s predation on sheep during a 2-year experimental program conducted by the New Mexico Department of Agriculture. Fifteen ranchers employed a total of 330 collars in field use. Two used collars in preventive control schemes and success was unknown. Thirteen used collars in corrective control (i.e. predation was in progress); 6 had collared lambs attacked and killed by coyotes; 4 had 1 or more collars punctured by coyotes and in 1 case a bobcat; 3 solved specific coyote …

Great Plains Wildlife Damage Control Workshop Proceedings

When F. Robert Henderson, the Extension State Leader of Kansas' Wildlife Damage Control Program, asked me for assistance in setting up a microcomputer system that would enable him to organize and analyze wildlife damage reports, I was surprised. "Certainly," I thought, "it's not because I am a social anthropologist and in my travels around the world I deal with some pretty wild life" No, Bob knew about my work with microcomputers in Anthropology and since we have been friends for some years he also knew that I would talk with him about the problems in using microcomputers. He also knew …

Reducing Goat Losses To Predators: Past Vs. Present Producers In Texas, Jerry H. Scrivner

Great Plains Wildlife Damage Control Workshop Proceedings

The purpose of this study was to gather information regarding the application and economic implications of predator control and husbandry methods used by 104 past and 103 present Angora goat producers in Texas. Of 7 techniques [(1) predator control by ranchers, (2) support of private or government trappers, (3) night penning of livestock, (4) confinement or semi-confinement kidding, (5) extra checking on goats, (6) the use of guard dogs, and (7) the use of scare devices] ranchers use to reduce predation losses, present producers used significantly more techniques than did past producers. Also, present producers generally implemented each technique to …

Use Of Aluminum Phosphide Fumigants For Burrowing Rodent Control, Carl Snider

Great Plains Wildlife Damage Control Workshop Proceedings

This article is to inform you about aluminum phosphide, a new burrowing rodent fumigant. The history of aluminum phosphide is long, dating back to the mid-1930'x, but the first aluminum phosphide preparation was not introduced into the United States until 1955. The traditional usage of phosphine throughout the USA has been in the grain and food industry in fumigating raw agricultural commodities, processed foods, animal feed, stored tobacco, and certain non-agricultural commodities. Aluminum phosphide was not approved in the U.S. for burrowing rodents until 1981.

Keynote Address, Robert J. Pool

Great Plains Wildlife Damage Control Workshop Proceedings

Most modern environmentalists during their formative years have had little actual contact with wildlife under natural conditions. Their wildlife philosophies have been developed via the mass media and from experiences with animals as pets or confined in zoos. In general, modern environmentalists are sincere, dedicated, idealistic and enthusiastic, but they often lack realism and are blessed with the innocence of naivete. The majority of people in the United States now exhibit strong affection for wild animals and are deeply concerned over any actions perceived as causing pain to individual animals. These attitudes towards wild animals will impact on future wildlife …
