Bait And Bait Materials, Fred R. Courtsal

Bird Control Seminars Proceedings

I'm going to speak about bird baits that are produced by the rodent-control fund. In my estimation, there are about six criteria for mixing good, high quality bait materials. The first one would be a toxicant. This is the first thing people talk or think about. I would assume that you would select a toxicant that has the quality to do the intended job. The second point is the sticker. So our criteria for a sticker are as follows: good adhering qualities, good spreading qualities (by this I mean if you introduce the toxicant into a sticker as is often …

To Kill Or Not To Kill : That Is The Question, John R. Beck, William J. Spitz

Bird Control Seminars Proceedings

In talking with the panel that has agreed to be with you this morning, we find that almost to a man they feel very strongly there is no "it" in bird control, that a good applicator needs to be well balanced and well rounded, that he needs to know, far more than one approach, that he needs to be able to understand people, biological problems, ecology, eco-nomics, and several other factors. The idea that sometimes comes across in meetings such as this is, and rightly so in some instances, "I have the final answer." Gentlemen, there is no "it" in …

Bird Problems At Military Airports, B. W. Brink

Bird Control Seminars Proceedings

I notice by the program that this was to be a progress report, new aspects of control. I'd like to narrow the scope a little bit, at least for my remarks; they will be essentially confined to activities of MAC, Military Airlift Command. There are 10 major commands in the Air Force. I'd like to reduce the word progress to lower case letters, at least; and I'd like to deemphasize the word new, for most of these things are not brand new for us. The scope of this problem is world wide, air force wide; and I'm going to confine …

Birds, Encephalitis, And Ectoparasites, Margaret A. Parsons

Bird Control Seminars Proceedings

Encephalitis or "inflammation of the brain" is a general term applied to a disorder which may have many causes. Usually this disorder is caused by a virus but it may also be produced by other types of micro-organisms. Encephalitis may also occur after an initial infection with mumps, measles and other childhood diseases, or following a vaccination, or as a result of a non-infectious process such as poisoning. Since encephalitis affects the brain, which in turn controls all body functions, encephalitis from any cause can show symptoms of general illness throughout the body such as headache, nausea and vomiting, fever, …

Status Of Bio-Sonics In Pest Bird Control, Gordon W. Boudreau

Bird Control Seminars Proceedings

Bioacoustics is defined as the study of biologically significant sounds ori-ginated by animals, and the mechanisms which produce and receive these sounds. Many of these sounds are audible to the human ear but some are above the human hearing range and fall into the ultrasonics class. There are sounds used by animals which are near or below the normal human hearing range in pitch, as in certain fish. Bioacoustics comprises a broad field of investigation and is an area which has only recently been explored. Improvements in electronic audio equipment have provided the impetus which launched recent bioacoustical investigations and …

Daily And Seasonal Susceptibility Cycles Of The Starling, Robert G. Schwab

Bird Control Seminars Proceedings

I would like to review a few of the characteristics of 3-chloro-p-toluidine hydrochloride (DRC-1339) prior to discussion on the daily and seasonal suscep-tibility of starlings to this avicide. DRC-1339 was screened and developed by the Denver Research Center (U.S.D.I.) and since has been tested in various portions of the country by the Denver Center and other organizations, including the State of California. In California we are much impressed with this compound for a variety of reasons, particularly the specificity of it to birds, ease in handling, ease in formulation, and many other characteristics which make this a highly desirable avicide. …

Chemical Bird Control: Idealism And Reality, James B. Elder

Bird Control Seminars Proceedings

Budding wildlife biologists, whether they wind up in research, management or administration, start out with one attribute in common. They are idealists. It is idealism to be sure, that quickly becomes tempered, if not blunted, by the realities of working for worthwhile, even essential conservation goals in an in-different and frequently hostile environment. For some, the conflict of ideals vs reality is too much and they move on to other, probably more lucrative occupations. Still others, blessedly few in number, lose their ideals completely, become apathetic toward wildlife goals and devolve into that most pitiable of human specimens, the bureaucratic …

The Role Of Fda In Environmental Contamination And Surveillance , Clifford Shane

Bird Control Seminars Proceedings

The Food & Drug Administration is concerned about birds in two areas. One is the direct contamination of foods, drugs and cosmetics by birds and the other is the possible contamination of these products by the chemicals used to control birds. Since its conception, the Food & Drug Administration has been concerned about the contamination of foodstuffs by birds. Like all animals, they have both their good and bad points. The one bad point is that they are carriers of certain diseases. In addition, the consumer of today is not ready to accept products which have been contaminated by fecal …

Pest Birds And Modern Architecture, Michael W. Fall, David E. Schneider

Bird Control Seminars Proceedings

We are offering some remarks on what the entomologist would call the areas of cultural control. Our interest in this approach developed out of a series of information discussions we've had concerning regional planning pro-grams at Penn State. Our ideas on the applications of this to bird management are not well developed; we'd be happy to hear your suggestions and comments. The ideas of cultural control are not new and are only one of many approaches. But perhaps we are reaching a stage of public concern about bird problems and about environmental contamination which make the climate for long range …

Presession Seminar On Blackbird Problems, Tom Stockdale

Bird Control Seminars Proceedings

I'd like to open with a very brief discussion, then call on some selected people with whom I've corresponded earlier, and ask if they will discuss a particular aspect of this total bird problem. I've asked that they keep their comments from three to five minutes. Trying to break the total problem down into its several facets we came up with six arbitrary subtopics. For want of better terms I've called these: population census techniques, chemical repellants, sonic repellants, wetting agents, lethal control techni-ques, and damage evaluation. Your particular problem in your area may be slightly different than in other …

Economic Analysis Of Alternative Flood Control Measures, L. Douglas James, Thomas M. Rachford, James Ray Villines, Clyde R. Dempsey, James Norris Cline, Carlos Fix Miller

KWRRI Research Reports

Within the last few years, the growing realization that an effective flood control program must include non-structural measures (land use management and flood proofing) has resulted in Presidential Executive Order 11296 requiring Federal agencies to seek the optimum combination of structural and non-structural measures for flood control. The requirement has created a dilemma. No methodology is available for systematic evaluation of alternative combinations of structural and non-structural measures. Prospective procedures are too time consuming to be feasible under current financial and manpower limitations.

The only way out is to perform much of the planning process by digital computer. With this …

Planning Flood Control Measures By Digital Computer, James Norris Cline, L. Douglas James

KWRRI Research Reports

The purpose of this study was to develop adequate guidelines whereby those interested in flood control planning would be able to apply a pair of digital computer programs known as the University of Kentucky Flood Control Planning Programs to ease the computational burden of evaluating specific flood control situations. Program II determines the economically optimum combination of channel improvement, land use restriction, and flood proofing for flood damage abatement. Program III also incorporates reservoir storage into the planning process. The Programs are not intended to provide a finished design but rather to select the optimum combination of flood control measures …

Limnology Of Selected South Dakota Lakes, Artwin E. Schmidt

Electronic Theses and Dissertations

Physical, chemical, and biological aspects of 45 lakes in South Dakota were studied from July 1965 to July 1967. Maximum water temperature at the surface reached 28 C. Most of the lakes studied exhibited continuous circulation except when ice covered. Thermocline formation was observed in six of the lakes. Light transmission was influenced by turbidity, and varied greatly within individual lakes and among lakes. Dissolved oxygen concentrations ranged from near saturation to less than the recommended minimum for fish life. All likes studied were basic ranging from a pH of 7.1 to 11.3. Specific conductance of lakes occupying open basins …

Fishes Of The Big Sioux River, James A. Sinning

Electronic Theses and Dissertations

An understanding of the fishes and limnology of a river is essential to the effective management of the river. The climate, soils, and agricultural practices in eastern South Dakota create unusual characteristics in rivers draining that area. One of the principal rivers of the area is the Big Sioux River. Fishes of this river were first studied about 1900 by Meek and by Everman and Cox (Bailey and Allum, 1962). A later survey by Churchill and Over (1933) apparently included the Big Sioux River, but collection data were inadequate for detailed comparisons. Since that time collections of fishes were made …

Evaluation Of The Legal Institutions Of Diversion, Transfer, Storage, And Distribution Of Water In Kentucky, A. Dan Tarlock

KWRRI Research Reports

In 1966 Kentucky enacted a water use regulation statute which makes :important modifications in the common law doctrine of riparian rights by authorizing the state to grant permits for the use of water. The permit system is primarily designed to allow the state to gather the information necessary to conduct long range planning studies. However, the permit system can also be used to apportion water among competing users. The report examined the common law of riparian rights to determine how KRS Ch. 151 had modified it and analyzed some of the legal problems which could arise in the administration of …

Evaluation Of Runoff Coefficients From Small Natural Drainage Areas, Carlos Fix Miller, L. Douglas James

KWRRI Research Reports

The Kentucky Department of Highways, as do most other agencies which build small drainage structures, estimates flood peaks as the product of a runoff coefficient, a rainfall intensity, and the drainage area, Available procedures were applied to 39 gaged watersheds in and near Kentucky and compared with the results of frequency analysis of historical stream gage records. The methods consistently underestimated the flood peak.

Therefore, a more intensive study (using the Stanford Watershed Model) of the runoff coefficient was undertaken by dividing it into overland flow and streamflow components. A set of curves was developed based on the 50-year event …

The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James

KWRRI Research Reports

It has long been realized that tributary urban development and channel improvement greatly affect the flow regime in a given watershed. A previous study used the Stanford Watershed Model to derive relationships expressing how the flood peaks in Sacramento, California, might be expected to vary with changing conditions of urbanization, channelization, and tributary drainage area. In order to observe the effects of climatic setting and geographical location on these relationships, the same type of analysis was applied to a drainage area near Louisville, Kentucky.

If reservoir storage is to be considered in a flood control program, it is necessary to …

Ecological Relationships Of Breeding Blue-Winged Teal To Prairie Potholes, Roderick C. Drewien

Electronic Theses and Dissertations

Ecology and behavior of breeding blue-winged teal (Anas discors) were studied in northeastern Day County, South Dakota in 1965 and 1966. Breeding pair use of the wetland habitat and importance of Type 1 ponds in the wetland complex were evaluated. Pair densities of 30.7 and 33.0 per square mile in 1965 and 1966, respectively, were above the 16-year average from 1950-66 and near maximum. Blue-winged teal comprised 46.7 percent of the waterfowl breeding population in 1965 and 51.7 percent in 1966. Number of water areas per square mile through mid-spring 1965 was comparable to the average for the 16-year period …

Distribution And Mortality Of Saskatchewan-Banded White-Fronted Geese, Harvey W. Miller, Alex Dzubin, John T. Sweet

Nebraska Game and Parks Commission: Staff Research Publications

At its annual spring meeting in 1959 the Technical Committee of the Central Flyway Council recognized a decreased population of the white-fronted goose (Anser albifrons). The recorded harvest in Canada and the United States had exceeded the estimated wintering population in some years. After summarizing records for the Central and Mississippi Flyways the Committee found them inadequate for management and to help fill this void, recommended banding on local concentration areas including Saskatchewan.

Urban Geology—A Need And A Challenge, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Urban land uses are rapidly converting open land into intensively used land. Generally, in planning those uses, a comprehensive study has included everything except an evaluation of the land in three dimensions. Geologists are eminently well equipped to supply the missing data, but they must also be aware of the needs of the urban community and the kinds of information needed by planners if they are to write reports usable by planners. Urban and environmental geology is a newly expanding field in the use of geologic data to help solve some urban problems in the planning stage. It is likely …

Survival, Growth, And Food Habits Of Brook Trout Introduced Into An Eastern South Dakota Stream, Larry W. Kallemeyen

Electronic Theses and Dissertations

Brook trout were introduced into the South Fork Yellow Bank River, an eastern South Dakota stream, on October 11, 1966. A supplemental brook trout plant was made on June 8, 1967. Survival for the initial plant from October, 1966 through October, 1967 was 2.4%. Survival for the supplemental plant from June, 1967 through October, 1967 was 21.0%. Trout from both plants took part in spawning activities during the fall of 1967. Average length of trout from the initial plant increased 9.8 cm during one year. Their average condition factor reached a peak in June, 1967 after being low throughout the …

Hydraulic Characteristics Of A Modified Venturi Section, Muhammad Aslam Rasheed

Reports

The measurement of water in open channels on extremely flat grades is difficult because of the head loss that is necessary. A modified venture section, the contraction of which is provided by a top cover section mounted in a rectangular flume, is proposed to meet the requirements of a suitable measuring device for use in canals of flat gradients. The method of finite differences has been used for the mathematical solution to the idealized inviscid flow problem. This was followed by a laboratory investigation to ascertain the hydraulic characteristics of the proposed design. The experiments were conducted in a 3 …

The Occurrence And Distribution Of Methane In The Marine Environment, Larry P. Atkinson, Francis A. Richards

CCPO Publications

The distributions of methane dissolved in the sulfide-bearing waters of the Black Sea, the Cariaco Trench, and Lake Nitinat are reported. The gas was not detected in the oxygen-deficient water of the eastern tropical Pacific Ocean, in the Santa Barbara Basin, nor in the sulfide-bearing water of Saanich Inlet. Maximum concentrations observed were 70 μmole CH4/l., and the distribution tends to follow that of sulfide. The data indicate that methane is derived from organic compounds not containing nitrogen or phosphorus and that its formation is much slower than that of sulfide. The solubility coefficient in seawater (salinity = 40‰) is …
