Leaf Epidermal Transmittance Of Ultraviolet Radiation And Its Implication For Plant Sensitivity To Ultraviolet-Radiation Injury, Ronald Robberecht

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Leaf epidermal transmittance of ultraviolet radiation (280-400 nm) was examined in several plant species to determine the capability of the epidermis to attenuate solar ultraviolet radiation. Epidermal samples were mechanically isolated and examined with a spectroradiometer/integrating sphere for transmittance. A survey of 25 species exposed to natural insolation was conducted. Although the species differed in life form, habitat type, and epidermal characteristics, epidermal transmittance was generally less than 10%. Ultraviolet radiation was attenuated 95 to 99% in more than half of the species. In 16 species, flavonoid and related pigments in the epidermis accounted for 20 to 57% of the …

Tests Of Bird Damage Control Measures In Sudan, 1975, Lee R. Martin

Bird Control Seminars Proceedings

The Red-billed Quelea (Quelga quelaa), because of its widespread destruction of grain crops throughout its range in Africa, is one of the most studied and written about granivorous bird species. Less publicized are more local bird pests in Africa which may be equally Important. The Village Weaver, (Ploceus cucullatus), for example, is a pest in many countries, while some other Ploecids with limited destructive habits create local problems. Significant crop losses also occur where there are large populations of Golden Sparrows (Passer luteus), House Sparrows (Passer domesticus), Red Bishops (Euplectes oryx), Doves (Streptopelia spp.), Glossy Starlings (Lamprotornis chalybaeus), Parakeets (Psittacula …

Plant-Animal Interactions: Simulation Of Bird Damage On Corn Ears, M. I. Dyer

Bird Control Seminars Proceedings

Within the past decade interactions among plants and animals have received increasing attention, mostly pertaining to selection of plants that produce toxic secondary compounds as a direct result of herbivory (Gilbert and Raven, 1975; Feeny, 1975; and Rhoades and Cates, 1976) and in turn selection of animals that detoxify these plant compounds (Freeland and Janzen,1974). Indeed, the plant-herbivore association has been regarded in the context of predator-prey relationships, especially for seed eaters (Scott, 1970, 1976; Janzen, 1971; Smith, 1975; and Pulliam and Brand, 1975). However, there are other important plant-animal associations. Regulation of plant nutrients (Mattson and Addy, 1975; Chew, …

Bird Problems And Food Storage And Processing Facilities, Robert M. Russell, Robert Yeager, Fred Baur, James R. Dupre

Bird Control Seminars Proceedings

For the bird control problems in the food industry I think we have a good pair to work with us. We have Bob Yeager, a pest control authority. Fred Baur is from Procter and Gamble, a great company with a long record of association with the pest control industry. Third, we have with us Jim Dupre, whose experience is with the Food and Drug Administration. And with all the government controls we've learned to expect from the government in the last few years, I think it's good for us to know that we have had a long and good record …

Redwinged Blackbird Flock Feeding Behavior In Response To Repellent Stress, M. I. Dyer

Bird Control Seminars Proceedings

The use of 4-Aminopyridine (Avitrol, a Phillips Petroleum trade-name, or AFCC 99, a name designated by Environmental Protection Agency) as an avian repellent when placed on agricultural crops has been reported upon (DeGrazio, et al., 1971, 1972; Stickley, et al., 1972, 1976); and its status in the United States and elsewhere has been recently reviewed (Bessek, 1976). Much more information has been collected; but unfortunately, it has not been made accessible in published form (see Besser, 1976). Thus, much of the information and opinions about this repellent material is anecdotal, and the scientific community must rely upon relatively sparse information …

Aircraft And Birds, Victor E. F. Solman

Bird Control Seminars Proceedings

At the third seminar I reported that our work on ecological changes at airports was a useful method of controlling bird hazards to aircraft. At the fifth seminar I talked about our studies of bird migration by radar and the use of that knowledge to keep flying aircraft away from bird concentrations. Those techniques are still effective. Since then we have: sought ground cover less attractive to birds than grass; developed methods of controlling earthworms to reduce bird attraction; improved radar data handling; improved bird hazard forecasts; studied light effects on birds; quantified bird spacing in flocks; studied the relation …

Winter Bird Roosts In Kentucky: An Introduction Of The Problem, Richard N. Smith

Bird Control Seminars Proceedings

When the first Bowling Green Bird Control seminar was held in the early sixties, emphasis on the blackbird problem was centered in Ohio. I believe John Beck, who is here, was one of the first peoples in the State to become involved with this situation. The problem (and it was a problem related to crop damage, primarily corn) had been building for a number of years, but it wasn't until September of 1965 that it really received national recognition. During that month, at the demand of local farmers at a meeting in Vickery, Ohio, Federal, State and local officials were …

Examination Of Redwinged Blackbird Nestling Growth Rates Using The Logistic Model: A Case For R And K Selection?, M. I. Dyer, Z. Abramsky

Bird Control Seminars Proceedings

One of the few processes of an avian population that presents the opportunity to collect sensitive information about the performance of that population is growth rates of young throughout the brooding period. Growth rate data are sensitive to many conditions of the breeding cycle: proximate influences, such as food availability and weather (Francis, et al., in prep.), and ultimate factors, such as species-specific characteristics, (Ricklefs, 1968). Additionally, the measurements themselves can be obtained with precision. The ability to make such detailed observations is extremely useful and is not always possible for other population parameters, such as determining life table data. …

Studies On Diet Overlap Among Icterids, Crows, And Starlings, M. I. Dyer, N. J. Kakalec

Bird Control Seminars Proceedings

Some of the problems that have been publicized for the past two to three years about blackbirds and Starlings in the southeastern United States are concerned with what these birds eat and the degree to which these granivores compete on their wintering grounds. The assumption by agriculturists has been that these birds cause severe depredations. Futhermore it is presumed by some that food supplies are unlimited and that these birds are simply living off the “fat of the land”; others consider that food is limited and that the birds are “pressured” into direct competition with man's food or food destined …

The Need For Practical And Objective Test Protocols For Bird Damage Control Chemicals, E. W. Schafer Jr.

Bird Control Seminars Proceedings

The registration and reregistration process for vertebrate pesticides is difficult at best and is becoming more complicated and time consuming each year, particularly for bird-damage control chemicals. Although much of the information that is required for U.S. registrations (such as toxicology, general chemistry, and analytical methodology) is beyond our purview at this seminar, there are some areas where research and management personnel can have a favorable impact on present and future requirements of the Environmental Protection Agency (EPA). I am speaking in particular of the methodology used to determine the laboratory and field efficacy of bird damage control chemicals. Because …

Starling Damage To Sprouting Wheat In Tennessee, Allen R. Stickley, Richard A. Dolbeer, Stephen B. White

Bird Control Seminars Proceedings

An estimated half-billion blackbirds and Starlings have been roosting in the United States each winter for many years (Meanley and Webb, 1965). Three-fourths of these birds, primarily Red-winged Blackbirds (Agelaius phoeniceus), Common Grackles (Quiscalus quiscula). Brown-headed Cowbirds (Molothrus ater), and Starlings (Sturnus vulgaris) winter in the east (lower Mississippi Valley and eastward to the Atlantic Ocean) where food and climate are apparently more attractive than in the more arid west.

In recent years, these birds have come increasingly to public notice because of appar- ent agricultural, health, aesthetic, and nuisance problems (Graham 1976). Considerable effort has been spent developing lethal …

Experimental Tree Trimming To Control An Urban Winter Blackbird Roost, Heidi B. Good, Dan M. Johnson

Bird Control Seminars Proceedings

Every fall millions of blackbirds come down the Mississippi Flyway to return to their winter roosts in Arkansas, Louisiana, and East Texas. When these roosts are located in urban areas, public pressure makes the more common chemical means of control impractical. A less destructive and more permanent method of control was sought. At Rice University, in Houston, Texas, there has been a blackbird roost of various sizes and durations since 1956. For the past two years we have had the opportunity both to study roosting blackbird biology and experiment with habitat alteration as a control method. This particular report concentrates …

The Good - The Bad - The Ugly - That’S Bird Control, William D. Fitzwater

Bird Control Seminars Proceedings

The good that most people see in birds is sometimes offset by the bad that birds do under certain situations. The ugly part comes in when misdirected emotionalism and unscientifically-based regulations interfere with effective control measures.

IV. Winter bird roosts - concentrations of blackbirds, starlings and robins with …

An Overview Of Depredating Bird Damage Control In California, Dell O. Clark

Bird Control Seminars Proceedings

To many people, California is synonomous with Disneyland, freeways, Los Angeles smog, Yosemite, the California missions, or for you bird aficionados, the California Condor. But do you think about California when you eat strawberry shortcake? You should -- California leads the nation in strawberry production. How about artichokes? California produces over 98% of the artichokes raised in the United States. Dates? California produces over 99% of the dates in the United States.

Yes, California is all of these, and it is much more. California may well be the most diverse state in the United States. Within its 100.2 million acres, …

Enteric Virus Survival In Package Plants And The Upgrading Of The Small Treatment Plants Using Ozone, Lois S. Cronholm, James R. Mccammon, Marvin Fleischman, Jerry R. Perrich, Valerie Reisser, William Harris, Ronald R. Vanstockum, Khosrow Jaberizadeh, Michael J. Wahl

KWRRI Research Reports

Post-chlorinated effluent collected with a portable viral concentrator from four treatment plants in Jefferson County, Kentucky, yielded infective viral particles from three plants from spring through late fall. The pH, ,chlorine, turbidity, and coliform levels of these effluents indicated that viral persistence was correlated with inefficient processing which produced effluent environments that inhibited disinfection by chlorine. The disinfection potential of ozone was tested on secondary effluent and finished water seeded with poliovirus and Esaheriahia coli. Low doses of ozone inactivated viruses and bacteria in treated water, but not in effluent. The inactivation of bacteria by ozone does not appear …

A Review Of The Limnology Of And Water Quality Standards For Lake Mead, Charles R. Goldman

Publications (WR)

1. The waters of Las Vegas Bay, a heavily utilized recreational resource, receive discharges from a variety of municipal and industrial waste sources. The U.S. Environmental Protection Agency has determined, on the basis of numerous studies, that the present water quality violates state and federal standards and constitutes a public nuisance. Consultants have advised the Sewage and Wastewater Advisory Committee that rapid abatement of the alleged pollution conditions can be achieved by an advanced wastewater treatment (AWT) plant.

2. The major problems in Las Vegas Bay are an objectionable water color, excessive turbidity, noxious odors, and oxygen depletion in certain …

Report On Wastewater Disposal To Board Of County Commissioners, Clark County Nevada, Clair N. Sawyer

Publications (WR)

This report is concerned with the management of waste-waters and subsurface drainage from the City of Las Vegas and its environs and the BMI complex, all in Clark County, Nevada. The prime objective is to recommend a plan of action which will utilize the natural resources of the area in the least costly manner and still protect Lake Mead for recreational purposes and use as a public water supply, At this writing, conditions in the upper Las Vegas arm of Boulder Basin are quite unsatisfactory for some recreational purposes due to the extensive blooms of algae which develop. Experience at …

Current Status Report: Pigeon Control, C. Doug Mampe

Bird Control Seminars Proceedings

My topic is Pigeon control; and because most of you have had some bird control experience, I'm not going to review all the basic concepts that are associated with bird control today. Rather I will skim over them lightly and then tell you how we organize most of our Pigeon control programs, recognizing that that's one approach and that some situations require much different approaches. Some of the things that apply to Pigeon control may apply to other types of bird control, but some are unique. When we get called on a Pigeon control job, the first thing we attempt …

The Arbovirus Surveillance And Control Program In Ohio, 1975 – 76, M. A. Parsons

Bird Control Seminars Proceedings

In 1975 Ohio experienced the largest epidemic of mosquito-borne encephalitis in its history. Four hundred and sixty-eight human cases (416 St. Louis [SLE] and 52 California [CE] occurred with 30 fatalities; one death was due to CE. The entire United States was hard hit (Illinois, 475; Indiana, 297; Mississippi, 210; Michigan, 20; Tennessee, 91; 30 others, 550 ) with 1816 SLE, 160 CE, 133, Western, and 3 Eastern encephalitis cases causing 150 fatalities. The cycle of mosquito-borne encephalitis in nature progresses as follows: A mosquito infected with virus feeds on a non-infected animal, such as a bird in the case …

State Of The Art Of Technology For Rural Water System Development, R. T. Alguire, Joe F. Nix, H. C. Macdonald, Robert E. Babcock

Arkansas Water Resources Center Technical Reports

The objective of this study was to review the current state of the art in rural water system technology. This was to be accomplished by a literature review of the Water Resources Scientific Information Center (WRSIC), National Technical Information Service (NTIS), and Smithsonian Science Information Exchange (SSIE). This literature search was to be augmented by interviews with consulting engineers, operating system managers and industrial literature. Both groundwater and surface water technology was to be reviewed. The technology was then to be grouped into four classes: (1) current technology, (2) technology which has been developed, but not currently being used, (3) …

A Survey Of Archeological And Historical Resources Within The Bonneville Unit Of The Central Utah Project, Frank W. Hull, Craig W. Fuller

Elusive Documents

Four small archeological sites were found but were of insufficient significance to warrant their further study or preservation. Providing the enlargement of Deer Creek Reservoir represents the only alternative, a comprehensive study of the community and its historic resources has been recommended, especially as it relates to the use of land and water. In addition, study has been recommended of the settlement as it relates to the understanding of agricultural development in Utah.
