Preliminary Interpretations Of Coyote Population Mechanics With Some Management Implications, Frederick F. Knowlton
Preliminary Interpretations Of Coyote Population Mechanics With Some Management Implications, Frederick F. Knowlton
Great Plains Wildlife Damage Control Workshop Proceedings
The need for control of coyote (Canis latrans) depredations and a simultaneous demand for recognition of the aesthetic and ecologic values of the species create a conflict in resource utilization that should be resolved through more intensive management. A coyote population model is proposed from current estimates of density, reproduction, population structure, and mobility. Densities of 0.5 to 1.0 coyote per square mile are frequently suggested, with occasional estimates of 4.0 or more per square mile. Reproductive rates fluctuate as functions of the proportion of females that ovulate, the average number of ova shed, and in utero viabilities. …
Removal Of Color From Surface Water In Central Florida, Joseph R. Wanielista
Removal Of Color From Surface Water In Central Florida, Joseph R. Wanielista
Retrospective Theses and Dissertations
The USPHS limits color in water to 15 color units. However, it is desirable to remove all the color. Color in surface water is mainly due to humic substances and was found in concentrations varying up to 450 color units. Removal of color by coagulation and flocculation has been practiced over the years. The mechanisms involved have not yet been fully understood. During the course of this investigation, a literature survey, studying the nature of color, mechanisms or color removal, and optimum color removal conditions, has been conducted. Samples have been obtained from surface waters in Central Florida; namely Big …

Exposure To Media Alternatives, Jack Burke
Great Plains Wildlife Damage Control Workshop Proceedings
Media use should not be a half way activity done after everything else on your mind is taken care of. The key word is commitment--if you are not ready to give proper preparation which includes understand what each (newspaper, radio, TV, etc.) does best, then don't do anything. There is at least a certain minimum quality standard that must be met--anything less and media exposure can hurt you and your program rather than help you. Seek help. Then select the media to fit your time, money and inclination. Example: Even if you don't buy time--television properly done may cost much …

A Brief History Of Extension Predator Control In Missouri, Dan F. Dickneite
A Brief History Of Extension Predator Control In Missouri, Dan F. Dickneite
Great Plains Wildlife Damage Control Workshop Proceedings
Missouri, like many of its neighbors, has long had to content with complaints of damage caused by predatory wildlife. Unlike some other states, however, in Missouri the control, management, restoration, etc. of all bird, fish and game and other wildlife resources of the state is vested in a Conservation Commission to an exclusive degree. Because of this Constitutional mandate, the Conservation Department in Missouri has been the agency primarily responsible for assisting farmers and ranchers with their various wild animal damage control problems. Poisons and explosive or chemical devices are not legal. This legal prohibition not withstanding, Missouri's relatively dense …

Summary, Dan F. Dickneite
Great Plains Wildlife Damage Control Workshop Proceedings
During this workshop we have heard from some of the leading animal damage control and livestock management specialists in the Great Plains and adjoining states. It appears that western states personnel will likely be involved in wild animal damage control to a greater extent than before as control activities are passed from federal to the separate state agencies--hopefully, with financial assistance for both implementation and research.
There is no widespread agreement on numbers or severity of damage, or on the best damage control techniques to use. What works in one area of the country will not necessarily work in another. …
Extension Wildlife Damage Control In Arkansas, Rocky Lynch
Extension Wildlife Damage Control In Arkansas, Rocky Lynch
Great Plains Wildlife Damage Control Workshop Proceedings
With the curtailment of a service type predator control program that existed in Arkansas for 29 years, the Arkansas Game and Fish Commission in 1970 initiated a Nuisance Animal Control Section within the framework of the Commissions' Game Division. This extension - demonstration type wildlife control unit was named such because of the increase in rodent control (beaver and muskrat) within the state. Their numbers were spawned by the habitat inhancement in the delta and timber growing regions of Arkansas.
A Game Biologist visited the Missouri Department of Conservation and observed the technique of their predator control agent. With ideas …

Extension Wildlife Damage Control In Colorado, Dale A. Wade
Great Plains Wildlife Damage Control Workshop Proceedings
Wildlife damage control in Colorado may be more varied and difficult than in some other states. Colorado has a widely diversified agricultural, industrial and recreational business base and a great range of human density from the Denver Metropolitan area containing approximately half of the state population to the semi-desert and mountain areas where the population density is extremely low.
Approximately 40 percent of the land is federally owned, much of this in large tracts in the western two-thirds of the state. Privately owned land in this western area is primarily distributed along the more accessible valleys of major drainages. It …
Social And Cultural Impact Of A Proposed Reservoir On A Rural Kentucky School District, Charles R. Smith, Philip Drucker
Social And Cultural Impact Of A Proposed Reservoir On A Rural Kentucky School District, Charles R. Smith, Philip Drucker
KWRRI Research Reports
This study utilizes anthropological concepts and research methods to study the educational system of a Central Kentucky school district with the goal of predicting the impact on it of a proposed multi-purpose (flood control, recreation, etc.) reservoir, and proposing options for forestalling dysfunctional aspects of that impact. The impact will result from the fact that although the county is now rurally oriented, the proposed reservoir will attract (has already begun to attract) urbanite residents from nearby Louisville, Kentucky's largest urban center, who can be expected to bring urban values concerning education, as well as other areas. To assess probable directions …
A Study Of Organochlorine Insecticides In Freshwater Crayfish -- Analytical Problems And Biomonitoring Survey, Robert C. Vanderjack
A Study Of Organochlorine Insecticides In Freshwater Crayfish -- Analytical Problems And Biomonitoring Survey, Robert C. Vanderjack
Masters Theses
Crayfish were collected from 3 sites on Polecat Creek, Coles County, Illinois in early spring, early summer, and late summer of 1972. Pesticides were extracted from the crayfish tissue in a one step procedure utilizing a Florisil elution column. Analysis was by electron capture gas chromatography. Pesticide residues in the nannogram range were analyzed and background contamination was an important consideration. Sources of background contamination were investigated and teflon stopcocks, Florisil, and residues on “cleaned” glassware were found to be major contamination sources. Distilled water used in flushing glassware should also be considered a potential contamination source.

Chemical Survey Of Selected South Dakota Lake Sediments, Alan Ross Swanson
Chemical Survey Of Selected South Dakota Lake Sediments, Alan Ross Swanson
Electronic Theses and Dissertations
Available phosphorus, organic carbon, and organic nitrogen were measured in bottom sediments of 16 lakes and ponds in northeast South Dakota. These lakes were glaciated, relatively shallow, and productive. Ranges of the surface sediments were: available phosphorus, 2 to 42 ppm; organic carbon, 0.94 to 5.34 percent; and organic nitrogen, 0.29 to 0.79 percent. Ranges of subsurface sediments were: available phosphorus, 2 to 39 ppm; organic carbon, 0.54 to 6.06 percent; organic nitrogen, 0.19 to 0.88 percent. Concentrations in most lakes varied little from top to bottom. Hard-bottomed lakes generally decreased in nutrient concentrations from sediment surface of subsurface. Lower …
Origin And Transport Of Nutrients In The Upper Big Sioux River, South Dakota, Charles William Thompson
Origin And Transport Of Nutrients In The Upper Big Sioux River, South Dakota, Charles William Thompson
Electronic Theses and Dissertations
The upper Big Sioux River Basin, in northeastern South Dakota, was studied to determine the origin and transport of nutrients in the Big Sioux River. The area was divided into three segments. Two of the segments, the Big Sioux River and Willow Creek Basins, were primarily agricultural drainage areas, and one segment was the city of Watertown. Sampling stations were selected to facilitate the determination of nutrient inputs to the river from each of these segments and to determine the nutrient load in the river leaving the study area. Nutrients studied included total orthophosphate and the particulate and dissolved fractions …

Sorption Kinetics Part I: A Laboratory Investigation Of Six Proposed Rate Laws Using Batch Reactors, David W. Hendricks, Laxman G. Kuratti
Reports
Six proposed rate equations for sorption kinetics have been investigated by laboratory batch experiments involving some 270 individual “runs” to determine sorption uptake with time for varying conditions of initial sorbate concentration, temperature, and sorbent species. The sorbate selected was rhodamine-B dye, used because it will sorb readily and is easily measured. Two sorbents, Dowex 50 resin, and Filtrasorb 200 activated carbon were used. Temperature conditions were 10, 20, 30, and 40°C, and concentrations ranged from .0008 to 400 micrograms per ml, rhodamine-B. Analysis of data was computer automated, requiring as input only test conditions, instrument readings, dilutions, and corresponding …

Social, Economic, Environmental, And Technical Factors Influencing Water Reuse, A. Bruce Bishop, Suravuth Pratishthananda, John Keith, Craig Colton, A. Berry Crawford
Reports
A growing population together with rising per capita income has resulted in increased demand for water for virtually all uses. At the same time there has been increased public concern for maintaining the quality of streams for recreation, sight-seeing, and other social uses, and to conserve environmental values. A partial answer to these conflicts in water use and management is more extensive waste water reclamation and reuse. Heretofore, water salvage and reuse has been mainly practiced in specific operational cases, such as recycling industrial process water, or on an ad hoc basis, such as a series of diversions and subsequent …

Sorption Kinetics Part Ii: Modeling Longitudinal Concentration Profiles In A Packed Bed Reactor, David W. Hendricks
Reports
A mass balance simulation model for sorption in a packed bed reactor was developed. All of the terms in the model, consisting of constants of the porous media, and functions, were evaluated by independent laboratory studies. The kinetic term was determined in Part I. Two numerical schemes (an explicit scheme and an implicit scheme respectively) with corresponding computer programs were developed and made operational. They were not tested against laboratory column results due to long times necessary on the computer and corresponding high costs. Laboratory testing consisted of measuring column profiles for six different packed columns at different flow rates …

Grey Kangaroo Management Programme, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
The Grey Kangaroo Management Programme, introduced in 1971 by the Department of Fisheries and Fauna, is designed to ensure the long-term conservation of the grey kangaroo, while at the same time recognising the right of the landholder to protect his primary production from damage.
One of the points which has arisen after examination of the programme is that some individual farmers are not fully aware of the requirements of the regulations.

D.C. Background On Predator Control Legislation, Michael Frome
Great Plains Wildlife Damage Control Workshop Proceedings
The tragic fiasco of federal predator control as we have known it is finished. The American people will no longer tolerate it. In this age of environmental concern, the people will not allow their tax dollars to be diverted for such a destructive and wasteful war against living wild creatures for the exclusive benefit of the sheep industry. There is now no turning back to old ways.
Indiscriminate trapping, shooting and poisoning have reduced some of the rarest, most beautiful and superbly adapted species of our wildlife heritage to the brink of extinction, although they consitutue a resource that could …
How Important Are Livestock Management Methods To The Orevention And /Or Reduction Of Losses To Coyotes, Don Good
Great Plains Wildlife Damage Control Workshop Proceedings
Professor.E. K. Faulkner, Extension Sheep Specialist from the University of Wyoming, stated that fencing the range was too expensive to be practical. He indicated that flares, pop-guns, color painting on sheep, and dogs have been used to cut down losses to coyotes but these methods have not been nearly so effective as the use of cyanide guns and 1080. He also indicated that losses to coyotes along with labor problems are the number 1 and 2 reasons for 200 sheepmen going out of the business the past 5 years in the range country. He said that shed lambing or lambing …

The Sport Hunting Of Coyotes, Edward L. Kozicky
Great Plains Wildlife Damage Control Workshop Proceedings
In an effort to gain some insight into the sport hunting of coyotes in Kansas, Bob Henderson circulated 586 detailed questionnaires and received 228 replies--an excellent voluntary response.
Time does not permit detailed comments on each question and reply. We shall only hit the highlights, and add some editorial comment where it seems appropriate.
It should be remembered that those who took the time to answer the 35 questions were devotees of the sport. This point is emphasized by the fact that of the 225 hunters who responded, 95 have been hunting coyotes for 20 years or more. The next …

Sport Hunting As A Method Of Damage Control, L. Boddicker
Great Plains Wildlife Damage Control Workshop Proceedings
Predator damage control is an area of concern to the livestock producer. He is also often the most likely person to choose sport hunting of coyotes as a recreational activity. Sport hunting of problem coyotes can be an effective tool.
Agricultural producers want to know the skills to control depredating wildlife. A high powered rifle, traps, and various related equipment are standard for most livestock production operations.
Through the Extension effort we attempt to help the producer develop wildlife damage control skills. It is also our responsibility to help develop alternatives to aid the livestock producer with persistent wildlife damage …

Phytoplankton Successions And Lake Dynamics In Las Vegas Bay, Lake Mead, Nevada, Ervon R. Koening, Richard W. Tew, James E. Deacon
Publications (WR)
Phytoplankton successions, applications of the general growth equation, and physical measurements have been employed to investigate events occurring at the interface between industrial and sewage effluent contained in Las Vegas Wash and the waters of Lake Mead, Nevada. The data indicate that the entering waters tend to form a density current interrupted at intervals by dynamic effects generated in the lake. The dynamic relationships described here for the spring months suggest that a much more thorough understanding of physical, chemical and biological interactions is necessary to permit solution of the numerous problems of Las Vegas Bay discussed or alluded to …
