Federal Wildlife Importation Regulations: The Why And Wherefore, Joseph P. Linduska

Vertebrate Pest Conference Proceedings: 3rd (1967)

This is a hasty and in many ways superficial review of the motivations that started us in the business of importing new, strange, beautiful, and hopefully useful wildlife. It is a capsuled account of the high cost of ill-advised introductions and of near misses that were avoided thanks to a few individuals who viewed such transplants with skepticism and even alarm. And I have touched also on the highlights of the legislative base from which we now operate in efforts to safeguard agriculture and other values from ravages of exotic wildlife; wildlife that may succeed too well with us and …

Literature is prepared and a museum is maintained. One of these courses, Epizootic Ecology, illustrates some of the aspects dealt with in these courses. Definitions and concepts are presented followed by a brief review of principles of epidemiology and ecology. Specific examples constitute the bulk of the course. One of these, tularemia, is especially useful for the purposes of this course …

Occasional Papers On The Limnology Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Nebraska limnological studies got under way throughout the state during 1966. Since this was the first full year of activities, field collections were made at as many sites as possible to accumulate extensive limnological data from which to determine lakes for future studies. A total of 44 reservoirs, natural Sand Hill lakes, rainbasin lakes, and Interstate 80 lakes was sampled. Methodology was perfected throughout the year in order to establish sampling techniques applicable to both natural and impounded waters.

Preliminary data revealed some conspicuous differences in physiochemical and biological characteristics from the geographically different regions of Nebraska. Distributions of properties …

Food Safety Program: Endrin Monitoring In The Mississippi River, Arthur F. Novak, M. R. Ramachandra Rao

Journal of the Minnesota Academy of Science

Twelve successive monthly samplings and analyses of representative fish and shellfish and of mud and water from the lower Mississippi River showed neither a high concentration of endrin nor a time-ordered change in the concentration. The general absence of endrin from the samples indicated no significant contamination.

The Fate Of Pesticide Residues In Soil, Russell S. Adams Jr.

Journal of the Minnesota Academy of Science

Pesticidal chemicals may be lost from or inactivated in soil by volatilization, leaching, sorption, chemical' degradation, microbial decomposition, or plant removal. The persistence of o pesticide in soil depends upon the chemical nature of the pesticide and certain characteristics of the soil. Soil mineral and organic colloids sorb these compounds very tightly and restrict microbial decomposition of the pesticide. Conditions favoring microbial activity in the soil also favor the disappearance of pesticide residues. Factors that contribute to the persistence of o pesticide ore the some factors that increase its persistence.

Arkansas Water Resources: Supply, Use, And Research Needs, Jared Sparks

Arkansas Water Resources Center Technical Reports

The purpose of this study is to identify Arkansas’ water resources research needs against an economic backdrop of water supply and use conditions existing in the state. In the aggregate Arkansas has an abundance of high quality water relative to present use. There are local conditions that give rise to water problems, but, in general, critical water problems in Arkansas are emergent and potential rather than actual. The causes of these problems are to be found, in large part, in the economic, legal, and social institutions surrounding water use--and particularly in the economic institutions. Research designed to improve economic efficiency …

Water Blooms, T E H Aplin

Journal of the Department of Agriculture, Western Australia, Series 4

WHEN a body of water becomes discoloured with a super-abundance of free-floating, microscopic plant or, in rare cases, animal life, it is said to develop a "water bloom."

This article discusses some aspects of the appearance of water blooms, particularly those caused by algae, and with the effects that certain toxic algae have on livestock.

Land Grading In South West Irrigation Areas, 1966-67, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Sales are made to the farming community and many trees are used by the Forest Department in its reafforestation programmes.

Fox-Prey Relationships In Eastern South Dakota, Robert L. Drieslein

Electronic Theses and Dissertations

Relationships between red foxes (Vulpes fulva) end their principal prey, particularly ring-necked pheasants (Phasianus colchicus), were studied on four units in eastern South Dakota from December 1964 to September 1966. Each unit was composed of a 100-square-mile "reduction area," on which fox populations were reduced, and a 100-square-mile "check area," on which fox populations were not reduced for the study. Indices to populations of foxes, pheasants, mice, eastern cottontails (Svlvilagus floridanus) and whitetail jackrabbits (Lepus townsendi) were obtained and used to evaluate food habits and the effect of predator reduction on prey populations. Four-hundred seventeen stomachs and 104 female reproductive …

Movement Of Forage Fishes In A South Dakota Stream, Thomas P. Felix

Electronic Theses and Dissertations

Movement patterns of Semotilus atromaculatus, Rhinichthvs atratulus, Campostoma anomalum and Catostomus commersoni were investigated in an eastern South Dakota stream for a period of one year. Electrofishing, fin clipping and a multiple census method were employed. Population structures were estimated for each species. Populations were considered unstable due to the occurrence of appreciable emigration and immigration between sampling periods. Differential size class mobility was established for all species. Species exhibited upstream movement tendencies during the summer and more random movement tendencies during the fall. Size classes of S.atromaculatus, R. atratulus, and C. anomalum showed differential upstream movement affinities. Considerable growth …

Seasonal Movements Of Prairie Grouse In South Dakota, Warren W. Jackson

Electronic Theses and Dissertations

From 1962 through 1966, 1,401 plains sharp-tailed grouse (Pedicecetes phasianellus jamesi) and greater prairie chickens (Tympanuchus cupide pinnatus) were trapped in Gregory and Lyman Counties in south-central South Dakota. Cannon-projected nets and funnel traps were used to capture prairie grouse on breeding grounds and winter baitsites. Some birds were marked with backtags and leg-markers. Movement information was obtained from field observations, hunter reports, sharp-tailed grouse collections, and by recapturing banded birds. Male birds moved less than two miles from winter baitsites to breeding areas; most movements over five miles were made by immature female birds. Seventy-seven percent of the hunter …

Factors Controlling Porosity And Permeability In The Curdsville Member Of The Lexington Limestone, William C. Macquown Jr., Jimmie L. Barr, George T. Hine, Jojok Sumartojo, Edward V. Peck, Franklin D. Thomas

KWRRI Research Reports

Factors controlling the porosity and permeability of the Curdsville Limestone Member of the Lexington Limestone of Middle Ordovician Age in the Blue Grass Region of Kentucky are geological.

Microstratigraphic analysis had led to the division of the lower Lexington Limestone, consisting principally of the Curdsville Member into three beds which may be subdivided into "zones" made up of several lithologic types and sub-types. Lower, middle, and upper bed characteristics are helpful in determining the regional depositional history in the progressively transgressing Curdsville sea. Paleogeography of Curdsville time has been determined by delineation of two local facies: (1) a carbonate bank--shoal …

Derivation Of Reservoir Operating Rules By Economic Analysis, Charles O. Dowell

KWRRI Research Reports

The purpose of this study was to develop a methodology for determining an optimum set of reservoir operating rules specifying the of storage space based on the example of Rough River Reservoir, a Corps of Engineers project in Breckinridge and Grayson Counties, Kentucky, and assuming this multipurpose reservoir provides flood control, water supply, and recreation. The operating rules were derived by the method of marginal analysis which uses as its criteria achievement of maximum net benefits from the available storage capacity.

Benefit relationships were derived for each use. The variation of flood control benefits with available flood storage was determined …

Review Of The Economic Benefits And Costs Resulting From Dewey Reservoir, David H. Rosenbaum

KWRRI Research Reports

The purpose of this investigation was to study the economic effects of the construction of Dewey Reservoir in Floyd County, Kentucky. Primary emphasis was placed on determining the degree the project had shifted income to this economically underdeveloped area by determining the incomes of those receiving project benefits and those paying project costs. The income redistribution effects of all benefits and costs associated with Dewey Reservoir were evaluated by assuming that the Federal income tax structure indicates the marginal value of income to individuals in the various income brackets.

Major benefits from the Dewey Project have been: flood control, $722,166 …

The Effect Of Landowner Attitude On The Financial And The Economic Costs Of Acquiring Land For A Large Public Works Project, John Malvern Higgins Jr.

KWRRI Research Reports

The purpose of this study was to examine the various economic and financial costs relating to the acquisition of property required for the construction of three reservoirs and to determine if any correlation could be made between the attitudes of the landowners selling property and the costs. Rough River Reservoir, Dewey Reservoir, and West Fork of Mill Creek Reservoir were studied. The costs involved in purchasing right-of-way were classified qualitatively and quantified to the extent possible. A procedure was devised to quantify 15 factors influencing attitude and an equation was derived to predict the landowner's attitude from these determining factors. …

Covariance Analysis Of Reservoir Development Effects On Property Tax Base, Claude M. Vaughan Jr.

KWRRI Research Reports

Much attention has been given in recent years to the development of water resources in the United States. Large scale multi-purpose dam and reservoir projects are of particular interest. Such projects are traditionally undertaken after the resulting benefit has been found to exceed the required cost. The benefits which are most readily evaluated are primary benefits such as flood control, hydroelectric power, and navigation. The purpose of this study is to investigate secondary benefits which accrue to local economies as a result of reservoir construction. The particular secondary benefit which this study evaluates is the reservoir impact on the local …

Analysis Of Reservoir Recreation Benefits, Robert Cecil Tussey Jr.

KWRRI Research Reports

Recreation visitation to two Kentucky reservoirs (Rough River and Dewey) constructed by the U.S. Army Corps of Engineers was studied to develop mathematical expressions for estimating numbers of visitors and recreation benefits. Regression analysis was used to relate characteristics of 168 origin areas (120 Kentucky counties, the District of Columbia, and the remaining states excluding Hawaii and Alaska) to visitation from that area to Rough River Reservoir. The resulting equations were then applied to Dewey to test their generality. Good results were obtained when only air distance and population were used as the independent variables. Correlations including the age and …

Effects Of Dieldrin On Reproduction Of Penned Hen Pheasants, Thomas Donald Atkins

Electronic Theses and Dissertations

Pen studies to determine the effects of dieldrin on reproduction of the hen pheasant were conducted for two breeding seasons, Hen pheasants were caged individually and administered encapsulated dieldrin at weekly intervals. The first season, treatment levels were 0, 2 or 4 mg of dieldrin per hen per week. Hens receiving 4 mg weighed more and laid heavier eggs than the controls. However, these differences were not attributed to the effects of dieldrin, but to the condition of the hens when first treated. Hatchability of eggs from the 2 mg group was significantly higher for an undetermined reason. Feed consumption, …

Rectangular Cutthroat Flow Measuring Flumes, Gaylord V. V. Skogerboe, M. Leon Hyatt

Reports

Introduction: Procedures and methods for more accurate measurement and improved management of water are continually being sought to make better use of our water resources. Of all the devices and structures developed for measuring water, measuring flumes are among the most widely accepted and used. The most common measuring flume is the Parshall flume developed by Ralph Parshall at Colorado State University. Common to most flumes is the basic geometry consisting of a converging inlet section, a throat, and a diverging outlet section. Occasionally, the diverging outlet section is removed under free flow conditions, and the water is allowed to …

Feasibility Study Of A Capacitance-Type Electronic Sediment-Sensing Device, C. Earl Israelsen, Duane G. Chadwick

Reports

Difficulties caused by sediment carried in natural streams have existed since earliest times. Although instruments and techniques for measuring stream discharge have existed for many years, only recently have attempts been made to measure sediment carried by the streams. The earliest observations of sediment discharge in the United States were made by Captain Talcott in the Mississippi River in 1838 (1). More or less continuous samples of sediment from the Rio Grande have been collected by the United States Geological Survey since 1879, and from the Colorado River Basin since 1925. Studies of sediment transport are seriously hampered by the …

Physicochemical Limnology Of Four Reservoirs In Southwest Nebraska, Donald L. Tennant, Robert E. Thomas, Robert E. Thomas, Joe Gray

Nebraska Game and Parks Commission: Staff Research Publications

Physicochemical data from four reservoirs in Nebraska taken within a 30-hour period in August, revealed moderate thermal stratification, closely associated in two reservoirs with the functioning low-level outlet. The reservoirs with thermoclines exhibited greater temperature ranges and contained cooler waters than did reservoirs without thermoclines. The distribution of fish as detected on sonar often revealed the presence and location of a thermocline prior to physical or chemical data verification.

Without exception, the larger the reservoir and the lower the outlet, the better the reservoir fishery. Downstream fisheries ranked the same with one exception.

The Ord River Catchment Regeneration Project. 1. The Nature, Extent And Causes Of Erosion In The Ord River Catchment Area, K Fitzgerald

Journal of the Department of Agriculture, Western Australia, Series 4

OF the 17,800 square miles of Ord River catchment area, an estimated 1,450 square miles of country is subject to varying degrees of erosion.

This lies astride the Ord River and its major tributaries, the Elvire, Negri, Stirling, Panton, Turner, Nicholson and RB rivers.

The bulk of the eroded country lies in W.A. but part projects into the Northern Territory.
