Biological Coal Desulfurization, Ming Le

Theses

Sulfur removal from coal before combustion is of considerable interest to avoid emission of oxides of sulfur(SO_x). Chemical and physical methods have been developed for removing the inorganic sulfur component in coal. This component is generally associated with pyrites(FeS2). However, no commerical methods have been developed for the removal of the organic sulfur conponent. This study describes microbial methods for removing organically bound sulfur from coal. The specific goals of this study were to ascertain whether a robust biologically active population such as activated sludge biomass can remove organic sulfur from coal and to devise sulfur analytical methods …

The Ecology Of Franklin's Ground Squirrel In Indiana, Peter M. Benjamin

All-Inclusive List of Electronic Theses and Dissertations

A reduction in the distribution of the Franklin's ground squirrel in the eastern portion of its range has led to its classification as a threatened species in Indiana. Information is lacking on this species' habitat requirements and population characteristics in Indiana, which limits management capabilities. The purpose of this study was to identify preferred habitat and population characteristics of the Franklin's ground squirrel in Indiana. Radio telemetry was conducted from April 1987 to September 1988 at 3 sites along a railroad right-of-way (ROW} in Benton County, Indiana. Land use and habitat types were mapped; species composition, density, percent cover, percent …

Is Rainbow Trout Condition Influenced By Invertebrate-Drift Density?, Randall B. Filbert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Users of the Instream Flow Incremental Methodology CTFIM) commonly assume that there is a positive linear relationship between available habitat (WUA) and stream fish biomass. However, several studies have shown a lack cf correlation between WUA and biomass. Such poor relationships may occur if other factors limit fish abundance. Food availability is a potentially important factor limiting abundance of stream fishes and can affect blomass by influencing fish condition (individual weight). I collected rainbow trout (Oncorhynchus mykiss) exposed to different levels of invertebrate-drift density to determine if condition was greater where food was more abundant. I also examined …

Microwave Treatment Of Hazardous Wastes : Chemical Fixation Of Insoluble Non-Volatile, Chemically Non-Reactive Organics In Soil, Naihong Zhu

Theses

Microwave treatment of hazardous wastes like dioxin-contaminated soil potentially fills a great need for a remediation technology which potentially can be applied in-situ: the EPA has concluded from a risk assessment study that it is the excavation and transportation of such wastes that poses the greatest risk. Studies have been carried out on a surrogate for dioxin, namely, 9,10-anthraquinone because it has similar chemical and physical properties but it is not toxic. It was found in microwave treatment studies that, at temperatures attainable in-situ, anthraquinone became non-extractable. A model was proposed which postulated that as water was removed from soil …

What's In A Name?, Robert S. Cook

Great Plains Wildlife Damage Control Workshop Proceedings

Communication is a vital part of this complex world in which we live. Even with the vast vocabulary that has evolved throughout recorded history, we still often find difficulty in expressing ourselves. As receivers of information, we struggle to grasp what the other person is trying to say. Also, when we speak to others, we struggle for the right words to use so that we can convey to that person exactly what we mean. The words we use and how we use them are very important to us as we communicate with each other. We have all experienced a time …

Environmentalism And Animal Welfare: Cornerstones Of Wildlife Damage Management, Rick D. Owens

Great Plains Wildlife Damage Control Workshop Proceedings

There are two issues which each of us, personally and as professional wildlife biologists, share a belief in, and which are essential to the conduct of our day-to-day wildlife management activities. Unfortunately, because of associated negative implications, we have failed to appropriately acknowledge and receive credit for our concerns regarding these issues. These are the issues of environmentalism and animal welfare. This discussion will serve to clarify what these terms should mean to us, why they should be considered cornerstones of wildlife damage management, and the actions we must take in addressing these issues. It is imperative that we become …

An Update On The Revision Of The Handbook, "Prevention And Control Of Wildlife Damage", Scott E. Hygnstrom, Robert M. Timm, Gary A. Larson

Great Plains Wildlife Damage Control Workshop Proceedings

Wildlife species have an important role in our environment and they provide many recreational, economic, and aesthetic benefits. Management of these species is necessary, however, when they cause damage to agricultural, industrial, and natural resources, and threaten personal property, public health, and safety. Published estimates indicate that commensal rodents, field rodents, and predators combined, cause >$2 billion in damage in North America annually. Because of the social and economic impacts of wildlife damage, there is a need for up-to-date information on the prevention and control of wildlife damage for producers, resource managers, administrators, and the public. The book, "Prevention and …

Damage Due To Scent Marking By Eastern Gray And Fox Squirrels, John L. Koprowski

Great Plains Wildlife Damage Control Workshop Proceedings

The stripping of bark by eastern gray squirrels (Sciurus carolinensis) is a serious problem in England with 50 to 100% of the trees damaged in some locations (Shorten 1957). The economic consequences of such damage have resulted in much research (Kenward 1982, 1983; Kenward and Parish 1986); squirrel-induced damage to trees also occurs in North America (Allen 1943, Brenneman 1954) but is rarely of the magnitude observed in England. At least 10 hypotheses (reviewed by Kenward 1983) have been suggested to account for bark-stripping damage including: 1) reduction of tooth wear; 2) uncontrolled gnawing reflex; 3) source of nesting material; …

Seasonal And Site Differences In Food Consumed By Double-Crested Cormorants In Arkansas, Albert E. Bivings

Great Plains Wildlife Damage Control Workshop Proceedings

Double-crested cormorants (Phalacro-corax auritus) are a common migrant in Arkansas in the fall and spring. In most years, many linger until freeze-up prior to moving south. In south Arkansas, they may overwinter if climactic conditions are not too severe. Although they were formally year-round residents, there are no current reports of substantial breeding flocks in the state. According to band returns, most cormorants found in Arkansas come from North and South Dakota, Wisconsin, Saskatchewan, or Manitoba (James and Neal 1986).

Previous investigations by Bivings et al. (1989) and Campo et al. (1988) reported that gizzard shad (Dorosoma cepedianum) comprised the …

Relative Effectiveness Of Repellents For Reducing Damage By Elk, William F. Andelt, Dan L. Baker, Kenneth P. Burnham

Great Plains Wildlife Damage Control Workshop Proceedings

We tested the repellency of chicken eggs, MGK' Big Game Repellent (BGR), coyote (Canis latrans) urine, thiram, Hinder', Hot Sauce Animal Repellent' (Hot Sauce), and Ropey on captive tame elk (Cervus elaphus) in Colorado from December 1990 to February 1991. Coyote urine and BGR performed better than the other repellents for deterring elk from feeding on cubed alfalfa rations. Consumption of cubed rations treated with odor repellents increased from Day 1 through Day 5 of the trial, but consumption of thiram-treated rations decreased. During the second phase of the study, hungry elk consumed significantly more apple twigs that were treated …

Burrow-Building Strategies And Habitat Use Of Voles In Pacific Northwest Orchards, Leonard R. Askham, James Sipes

Great Plains Wildlife Damage Control Workshop Proceedings

Seidel and Booth (1960) wrote that the "life histories of the genus Microtus are not numerous in the literature." In support of his observation he cited 6 publications, all dated between 1891 and 1953. Since then the literature has exploded with a proliferation of publications. An international literature review recently revealed over 3,500 citations for the genus. When Pitymys and Clethrionomys are included another 350 and 1,880, respectively, were found. Over the last 10 years approximately 3 new publications on voles appeared every 4 days; a significant output for what some would consider such an insignificant species. Most of the …

Home Ranges And Movements Of Coyotes In The Northern Chihuahuan Desert, V. W. Howard Jr., Gino G. Delfrate

Great Plains Wildlife Damage Control Workshop Proceedings

The coyote (Canis latrans) is among the most studied animals in North America. Because of its adaptability and success as a predator, the coyote has flourished and is still expanding its range. Coyotes can now be found throughout most of North America and south into Central America (Voight and Berg 1987). Studies in recent years have been extensive to understand the interrelationships of prey and coyotes (Shelton and Klindt 1974, Beckoff and Wells 1981), as well as demographic relationships (Davis et al. 1975, Knowlton and Stoddart 1978, Mitchell 1979, Bowen 1981) and feeding strategies (Todd and Keith 1976, Andelt et …

Developing A Coordinated Statewide Wildlife Damage Management Research And Extension Education Program, Paul D. Curtis, Daniel J. Decker

Great Plains Wildlife Damage Control Workshop Proceedings

Dealing with the negative side of human-wildlife interactions has become an increasingly important part of wildlife man-agement. This situation is due to a combina-tion of factors: human population growth and urbanization, patterns of land use associ-ated with human activities, and the increase in abundance of some wildlife species that cause problems for people. A broad consen-sus exists among state wildlife agency staff, state agricultural department staff, wildlife extension specialists, U.S. Department of Agriculture-Animal Damage Control agents, and state Farm Bureau officials that wildlife damage on agricultural lands has increased during the past 30 years, and white-tailed deer (Odocoileus virginianus) currently …

Opening Address:, Kenneth R. Bolen

Great Plains Wildlife Damage Control Workshop Proceedings

Nebraska is a major agricultural state. Nebraska ranks first in the nation in number of cattle on feed and fed cattle marketed, second in cash receipts from all livestock marketing, first in production of Great Northern beans, popcorn and alfalfa meal, and third in corn production. Agriculture is important to the state's economy. Some economists project that one-half of Nebraska workers depend on agriculture and the many related industries for their employment. The annual value of agricultural production in Nebraska is more than 8 billion dollars. Agriculture and wildlife damage problems often go hand-in-hand. We have problems in agricultural situations …

Landscape Plants, Forest Trees, And Crops Most Resistant To Mammal Damage: An Overview, Rex E. Marsh

Great Plains Wildlife Damage Control Workshop Proceedings

To capitalize on mammal-resistant plants, several approaches may be taken. The most common is to select crops not highly prone to mammal damage (i.e., resistant crops). If a generally susceptible crop is to be grown, the more resistant varieties or cultivars of that crop can be selected, if known. An approach that has not received the attention it warrants is the selection of parent stock with resistant characteristics and the selective breeding of useful species to develop strains, hybrids, or cultivars with improved mammal resistance. For several reasons, this latter approach shows the most promise for forest tree species. It …

Vertebrate Impacts On Oak Regeneration In California: A Review Of Management Options, Robert H. Schmidt, Robert M. Timm

Great Plains Wildlife Damage Control Workshop Proceedings

Hardwoods occupy about 25% of the total forest area in California (Bolsinger 1988). Predominant among the hardwoods are oaks (Table 1). Over the past 10 years, concerns have been raised about the ability of some oak woodland stands to replace themselves. These concerns have focused on 2 distinct management dilemmas. The first involves the gradual loss of oak woodland acreage due to human activities. These activities often involve some type of conversion, such as the clearing of trees for rangeland improvement, production agriculture, or residential development (Schmidt and Tietje 1987). The rapid increase in California's population means more pressure on …

Effectiveness Of Nylon Lines For Deterring Rock Doves From Landing On Ledges, William F. Andelt, Kenneth P. Burnham

Great Plains Wildlife Damage Control Workshop Proceedings

Abstract: The effectiveness of 74-kg, white, twisted nylon twine was evaluated for deterring rock doves (Columba livia) from landing on ledges at Colorado State University's Hughes Stadium in a controlled experiment during 1990. One, 2, and 3 lines were stretched 8 cm in front and 12 cm above (1 line), 8 and 18 cm above (2 lines), and 5, 12, and 18 cm above (3 lines) the ledges. The proportion of successful landings to attempted landings was reduced from 0.99 (0 lines) to 0.23 (1 line), 0.13 (2 lines), and 0.10 (3 lines). The number of pretreatment landings per ledge …

Plate Tectonics, Space, Geologic Time, And The Great Plains: A Primer For Non-Geologists, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

For most Americans, "The Great Plains" evokes images of grasslands, dust storms, prairie fires, Native Americans on horseback, cowboys and wheat lands, and perhaps flat valleys crossed by braided rivers carrying a heavy load of sand and gravel, extremes of weather, and a climate typified by an alternation of droughts and wetter periods. Geologists picture such general images, too, but they also see radical changes in the landscape over periods expressed in millions rather than hundreds of years. Geologically speaking, human activities on the Great Plains are too recent to have much of a place in the broad geologic history …
