Rust Diseases Of Apple, John R. Hartman

Agriculture and Natural Resources Publications

Three related rust diseases occur on apple trees in Kentucky: cedar-apple rust, cedar-hawthorn rust, and cedarquince rust. Crabapple, hawthorn, mountain ash, pear, and serviceberry are also susceptible to these diseases. All three rusts are caused by different species of the fungus Gymnosporangium, each of which must spend a phase of its life cycle as a parasite on Juniperus species such as native red cedars or ornamental junipers.

Although cedar rusts can cause unsightly growths on Juniperus, they do not usually cause serious damage to these plants. Rust diseases can cause serious losses on apples, however, as a result …

Private Lands: The New Frontier For Wildlife And Recreation Management, Delwin E. Benson

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

Private lands are the new frontier for managing wildlife that covers two-thirds of the United States, provides habitat for 85% of wildlife, and offers opportunities for outdoor recreation. Wildlife and recreation are increasingly viewed as a product of agricultural and forest lands rather than by-products. The role of landowners to manage wildlife on private lands and the incentives to do so are unclear. Historical conflicts between governments and landowners make working together a new challenge. The "debris" of controversy erodes the building blocks for solutions; thus, debates about governmental controls over wildlife must be replaced with the pragmatic recognition that …

Exotic Aquatic Plants-Some Good; Some Bad, James T. Davis

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

Aquatic plants, like all other plants, may be weeds in one location and a source of income and therefore coveted in another location. Introduction of exotic aquatic plants to the United States has always proceeded at a rapid rate. Many plants were brought in for horticultural or agricultural purposes. A greater number of aquatic species were brought in as aquarium plants and then accidentally or purposely introduced into the wild as a future source of income. A much lesser number have been introduced into natural waters from ballast pumpage. Most are of tropical or semi-tropical origin and initially were confined …

Plenary Session—Welcome And Opening Remarks, Edward J. Depuit

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

I vastly appreciate the opportunity of being with you all today to help launch what, I am certain, will prove an extraordinary workshop. I bring you specific greetings and words of welcome from colleagues in eastern Washington and elsewhere in the interior Pacific Northwest and particularly from the organization that John Munn and I work for, the College of Agriculture and Home Economics and Cooperative Extension, Washington State University. We are delighted indeed to have this meeting in our corner of the world this year.

National 4-H Sportfishing Program, Catherine A. Elliott

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

In May I went to the Cornell Biological Field Station with nine volunteers from Maine to attend the pilot training for the National 4-H Sportfishing Program. While I was there, Ron Howard, chair of the program development committee, asked if I was coming to this meeting, and if so, would I speak about the sportfishing program. In the euphoria of the moment, I said yes, then immediately began to wonder why I had said yes. Although I live more than 50 miles from here, I am giving this talk without slides and I haven't been fishing for over 25 years, …

The American Farm Bureau Federation's Perspective, Herbert F. Manig

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

A fledgling Extension Service learned a lesson early in this century; a lesson that is perhaps more valid today than when it was learned, and a lesson that may be particularly useful to professionals in wildlife and fisheries.

As improvements in agricultural production techniques and procedures were developed by the university agricultural experiment stations, there was an obvious gap between those who possessed the new information and those who needed to adopt it. To meet that need, programs were developed that resulted in professional change agents residing among farmers and ranchers in order to extend the universities' influence by one-on-one, …

Managing Recreational Fish Ponds, Michael P. Masser

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

Kentucky has over 135,000 farm ponds. These ponds are used for irrigation, watering livestock, and recreation. However, most ponds are under-utilized for recreation. Existing ponds can provide excellent recreational opportunities if properly managed.

The first step in recreational pond management is to determine the pond's purpose. Ponds can be managed for swimming, fishing, aesthetics, and to attract wildlife. It may be difficult to manage for all of these things simultaneously. The pond owner must decide about goals or what is most important. If fishing is the desired objective, the following should help.

The Personal Approach To Put Theory Into Practice, Delwin E. Benson

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

Personal traits and techniques of facilitators enable theory to affect practice. Facilitators are guides working within the ethos of the situation to reduce stresses, open the minds of participants, and clear the paths of communication to find what can be accomplished instead of preserving the status quo of what cannot be accomplished. Facilitators should leave their biases at the door and help others to do the same, except for upholding two considerations: 1) the integrity of resources in question; and 2) the dignity of persons who question. Abilities to do the right job are as important as doing the job …

Extension Program Development: Evolution In Changing Environments, Ronald A. Howard Jr.

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

As I was developing these brief comments, I considered using the title, "We're not in Kansas Anymore, Toto." While some of the things we need to do are the same ones we have been doing for the past 30 years, others are quite different—primarily the environments, audiences, or types of requests. Some of that is adaptive reiteration. We have needed to learn new things to treat the needs of new audiences. Perhaps we use wood duck nest structure experience to assist an urban homeowner in placing bat boxes, or answer questions about how to colonize a pond with snakes and …

Maintaining Conventional Septic Systems, William O. Thom, Pat Keefe

Agriculture and Natural Resources Publications

Septic systems are used in Kentucky where municipal sewage treatment is not available. They are an effective, longstanding method of collecting, treating, and disposing of homeowner wastewater, provided they are properly sited, installed, and maintained. However, a well-sited, properly sized and installed system will fail if not properly maintained. A failed septic system creates problems such as noxious odors, lowered property values, surface water contamination, and groundwater pollution and may be a health hazard. Repair and replacement costs are considerable. Additional information on assessing septic system performance and reducing the potential risk of groundwater contamination is available from a KY-A-Syst …

Twig, Branch, And Stem Diseases Of Pine, John R. Hartman

Agriculture and Natural Resources Publications

Tip Blight

Tip blight, caused by the fungus Sphaeropsis sapinea (formerly Diplodia pinea), is a serious disease of mature Austrian, Scots (Scotch), and Mugo pines in Kentucky. In the landscape, tip blight is normally not observed until pines reach about 12 years old and begin to bear cones. Severe infections year after year can greatly weaken and eventually kill affected pines.

Metal-Resistance Genetically Engineered Bacteria, Sylvia Daunert, Donna Scott, Sridhar Ramanathan

KWRRI Research Reports

Bacterial-based electrochemical and optical sensing systems that respond in a highly selective and sensitive manner to antimonite and arsenite have been developed. This was accomplished by using genetically engineered bacteria bearing one of two plasmids constructed for our studies. The first plasmid, pBGD23, contains the operator/promoter region (O/P) and the gene of the ArsR protein from the ars operon upstream from the β-galactosidase gene. In the absence of antimonite/arsenite, ArsR binds to the 0/P site and prevents the transcription of the genes for ArsR and β-galactosidase, thus blocking expression of these proteins. When antimonite or arsenite is present in the …

The Regulation And Development Of Bioremediation, Susan J. Timian, D. Michael Connolly

RISK: Health, Safety & Environment (1990-2002)

The authors describe how federal statutes regulating hazardous wastes create both incentives and disincentives for exploiting the large potential of bioremediation. Ultimately, they argue for regulation attending more to comparative risks and costs.

Hepatic Cytochromes P450 Enzyme Activities Of Uae Coastal Rabbit Safi Fish Siganus Canaliculatus, Amna Mana Al-Otaiba

Theses

The cytochrome P450 dependent metabolism of benzo(a)pyrene and other xenobiotics has been investigated in liver microsomes prepared from a local marine Safi fish Siganus canaliculatus caught from the Arabian Gulf of United Arab Emirates. The Safi fish was found to have a well developed liver microsomal monooxygenase system consisting of cytochrome P450, cytochrome b5 and NADPH-cytochrome c reductase. The fish microsomal enzyme system was able to metabolise benzo(a)pyrene, 7-ethoxycoumarin and 7- ethoxyresorufin. Male fish were found to exhibit a higher monooxygenase activity than female fish. Treatment of fish with β-naphthoflavone was found to induce (2-4 fold) the activities of aryl …

Environmental Study Indoor And Outdoor Of The Abu Dhabi Compost Plant, Jaber Eidha S. Aljabri

Theses

The transformation of municipal solid waste into compost is of double interest: on the one hand, it helps to avoid the deficiencies of natural manure, and on the other it eliminates this major polluting agent which is increasing progressively as a consequence of rising populations.

Domestic waste produced per person per annum amounts to 730 kg in Abu Dhabi city. Based on a population in 1992 of 574,745, this gives a current daily refuse collection that amounts to 1120 tons. Refuse is reported to contain a high proportion of organic materials and therefore to be suitable for recycling to produce …

Application Of Tube Settlers In Secondary Wastewater Treatment, Abdulsalam Mohamed Saleh Kamalpoor

Theses

Secondary sedimentation is one of the most commonly used unit operations in wastewater treatment plants. It is customary designed to achieve solids separation from biologically treated effluent through clarification of biological solids and thickening of sludge. As treatment plants receive increasingly high wastewater flow, conventional sedimentation tanks suffer from overloading problems which result in poor performance. Inclined plate settlers, a form of tube settlers, may have good potential in upgrading sedimentation tanks. This study was conducted to examine the possibility of applying inclined plate settlers in secondary sedimentation in order to upgrade conventional rectangular sedimentation tanks and improve their performance. …

Continuous Monitoring Of Volatile Organic Compounds Using Microtrap Based Gas Chromatographic Systems, Yonghua Xu

Dissertations

Continuous analysis allows a representative portion of a sample to flow continuously through an analytical instrument, which gives analytical information with little or no delay in time. A microtrap is a small diameter tube packed with adsorbents in series. When a gaseous sample containing volatile organic compounds (VOCs) flows through the microtrap, the VOCs can be trapped selectively by adsorbents. Then a pulse of electrical current is applied to the microtrap. This rapid heating results in a desorption that can act as a sharp injection for GC separation. Thus the microtrapped sample is the total amount of VOC present in …

Stratospheric Ozone Layer Depletion : A Computer Aided Case Study, James M. Lipuma

Theses

In industries today, there is a desire to stop pollution before it starts, through the process of pollution prevention. Unfortunately, many university level students are not exposed to the thinking process involved in environmental problem solving early enough in their academic career, if they are exposed to it at all. The goal of this thesis is to develop and to evaluate an interdisciplinary case-study about the depletion of the stratospheric ozone layer by chlorofluorocarbons (CFCs). This case-study will be used to teach first year chemistry students about environmental problem solving. The case study was assembled from existing literature according to …

Longevity Of Woodhouse's Toad In Colorado, Richard M. Engeman, E. Marie Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

Little is known about the longevity of amphibians in nature. Records from captive specimens have demonstrated life spans of 10 to 20 yr for a number of anuran species, including 36 yr for Bufo bufo (Duellman WE, Trueb L. 1986. Biology of Amphibians. New York: McGraw-Hill. 670 p). Here, we report on a male Woodhouse's toad (Bufo woodhousii) which appeared in 1978, and has apparently remained since, in a basement window well of a brick home in an unincorporated western suburb of Denver, Colorado (T3S, R69W, 530). In the intervening years no other toads have been observed in …

Identification Of Optimal Locations For Sampling Ground Water For Pesticides In The Mississippi Delta Region Of Eastern Arkansas, H. S. Lin, H. D. Scott, J. M. Mckimmey

Arkansas Water Resources Center Technical Reports

Concerns about the presence of pesticides in the Mississippi River Valley alluvial aquifer in the Arkansas Delta have generated the need to develop a map of ground water vulnerability for this region comprised of approximately 10 million acres. Based on the availability of digital data and the scale of this study. we used a modified Pesticide DRASTIC model in a GRASS GIS environment to identify areas that were physically more sensitive to pesticide contamination than other areas within the Delta. Spatial distribution of pesticide loading was estimated from pesticide application rates in different crops and crop distribution map interpreted from …

Environmentalism In The United States: An Evolving Perspective, Mary Snow

Masters Theses & Specialist Projects

The purpose of this study is to investigate environmentalism in the United States. The dimension of perspective receives considerable attention. The prevailing perspective by a society regarding the importance of the health of the natural world greatly influences the degree of support of environmental organizations, environmental policy, as well as the direction charted for the future of that society. The perspectives of the Native Americans and the dominant European cultures which arrived in North America are presented and contrasted. It is supposed that the perspective which prevails in the United States regarding the importance of the natural world is evolving. …

Ecology, Economy And Ecotourism: Sustaining People And The Environment, Richard Snow

Masters Theses & Specialist Projects

Tourism is the world's largest industry. The fastest growing segment of the travel and tourist trade is ecotourism. The concept of sustainable development insists that humans cooperate with nature in the search for an ecological economy which can support present and future populations. Ecotourism attempts to attain this elusive goal by preserving ecosystems while generating revenue for local communities. In this study, the researcher examines the positive and negative effects of ecotourism on people, culture, and landscape. An analysis of tourism data seems to suggest that developing countries, which are popular ecotour destinations, are benefitting economically and ecologically from properly …
