Blood And Tissue Identification Of Selected Birds And Mammals, Part Ii: Cross Reaction Patterns Of Birds And Mammals, Using Deer, Bovine, Raccoon, Chicken And Mallard Duck Antiserum, Part 1, David W. Oates, Debra L. Weigel
Other Publications in Wildlife Management
Most enforcement cases involving our laboratory deal with the identification of a blood stain or meat sample which is suspected to be deer. Determining whether it is, indeed, from deer is not difficult. But, if the sample is not deer, exact identification can prove to be a more time consuming and tedious process. To eliminate the need to obtain antiserum for each individual species and aid identification, we undertook an investigation on which species and the extent to which several species may cross react with antisera of some common birds and mammals, especially deer. Deer, cow, and raccoon were selected …
Use Of Stockpods For Nesting By Giant Canada Geese, Paul M. Bultsma
Use Of Stockpods For Nesting By Giant Canada Geese, Paul M. Bultsma
Electronic Theses and Dissertations
A study of giant Canada geese (Branta canadensis maxima) nesting on stockponds in western South Dakota was conducted during 1974 and 1975. Analysis of 10 selected variables at nests on natural sites indicated that distance of water below high water level and percent slope from wetland to horizon, contributed the most to the use of the site. Distance from wetland to horizon and disturbance factors were two important variables measured to determine use of artificial nesting structures. First nests were initiated on 1 April 1974 and 8 April 1975. Twenty-five nests (16 percent) were located on artificial nesting structures, and …
An Evaluation Of The Fishery Resource In A Portion Of The James River, South Dakota Scheduled For Channel Modification, Dennis Tol
Electronic Theses and Dissertations
The fish populations of a 193 km (120 mi) section of the James River between Tacoma Park and Redfield, South Dakota that is scheduled for stream modification under the Oahe Irrigation project were evaluated from October 74 to July 76. Twenty-two species of fish were captured in the James River between Tacoma Park and Redfield, South Dakota. The fishes use the area primarily as a spawning ground and nursery for young-of-the-year. Evidence of spawning was found for 19 species of fish. Only a residual population of forage fishes, young-of-the-year of various species, and a few adult black bullheads attempt to …

Evaluation Of The Addition Of Granular Media Filtration To Wastewater Treatment Plants To Meet New Standards, Madhusudan M. Dawda, M. L. Davidson, E. J. Middlebrooks
Reports
A dual media filtration study was carried out at the central Weber Wastewater Treatment Plant in Ogden, Utah, to evaluate its feasibility as a tertiary treatment to meet new effluent quality standards. A review of the literature indicated that dual media filters were more efficient than conventional single media sand filters because of the “in depth” filtration achieved by dual media filters. An experimental filter was operated at four different hydraulic loading rates, ranging from 3 to 6 gpm/ft 2 (122.10 to 244.20 1/min/m2), to evaluate its effects on effluent quality. Hydraulic loading rate was shown not to affect suspended …

Colorado River Basin Modeling Studies: Proceedings Of A Seminar Held At Utah State University Logan , Utah July 16-18, 1975, Calvin G. Clyde, Donna H. Falkenborg, J. Paul Riley
Reports
Preface: Computer modeling is an important and valuable tool for water resources planning and management. In recent years many different modeling approaches and techniques have been developed. Some have been applied in the Colorado River Basin. A brief and incomplete search showed over fifty reports on modeling in the Colorado River Basin alone. The main motivation for this Seminar was the indication that (1) much duplication of effort is occuring among Colorado River modeling studies due to lack of information and (2) much of the knowledge now available on modeling is not being effectively applied to real problems. The overall …

Iron Dynamics In A Gas-Water-Sediment Microcosm, Peter A. Cowan, V. Dean Adams, Donald B. Porcella
Reports
Iron dynamics in eutrophic systems were studied in the laboratory utilizing gas-water-Sediment phase sealed microcosms. Sediments from Hyrum Reservoir (2.4 percent iron by weight) were placed in the dark to simulate the hypolimnetic regions of a eutrophic impoundment. Iron both chemically and physically was readily available to microorganisms of the aqueous phase because iron in these systems was soluble. In the light microcosms, which simulated shallow littoral regions of eutrophic impoundments, iron was found in higher aqueous phase concentrations than was predicted chemically and physically; this was rationalized through biological mechanisms. The experiment was conducted in two phases: Phase I …
The Effects Of Boating Upon Lead Concentrations In Fish, David Oates
The Effects Of Boating Upon Lead Concentrations In Fish, David Oates
Nebraska Game and Parks Commission: Staff Research Publications
The concentration of lead in fish muscle tissue from lakes where boating is heavy and where it is prohibited was measured. The lead levels ranged from less than 0.05 to 1.35 ppm but did not differ significantly between those in the controlled and non-controlled boating lakes. Lead levels apparently pose no public health hazard.

An Overview Of Problem Bird Management - Rural And Urban, Joseph L. Guarino
Great Plains Wildlife Damage Control Workshop Proceedings
The economic impact of birds on agricultural crops in the U.S. is quite substantial -- perhaps as much as $100 million dollars. Methods for reducing this damage can be categorized as biological, mechanical, and chemical. The chemical approach appears to have the most potential. An avian repellent, methiocarb, has proven to be effective for reducing damage by a variety of species of birds to many sprouting and ripening crops and fruit. An avian chemical frightening agent, 4-aminopyridine (Avitrol), if federall registered for use for protecting ripening field corn and sweet corn and was shown to be effective for reducing damage …

Bats, Biology, And Control, Stephen P. Kincaid
Great Plains Wildlife Damage Control Workshop Proceedings
Although bats are not commonly thought of as major members of the animal kingdom, they are one of the most numerous of land vertebrates. Bats are thought to have originated in the Old Wordl Tropics and are now almost world-wide in distribution. Bats make up the order Chiroptera, and they are closely related to the hedgehog, shrew and mole.

Analysis Of The Sediment Filtering Action Of Grassed Media, Billy J. Barfield, David T. Y. Kao, E. W. Tollner
KWRRI Research Reports
The movement of sediment in non-submerged flow through a rigid grass media was studied experimentally by simulating the media with cylindrical nails. Models of sediment movement were developed from probablistic reasoning and from the use of existing parameters describing total bed material in open channel flow. In the probability analysis, the percent sediment trapped was found to be a power function of the number of potential fall paths, Nf,a particle could make from the surface to the bed while traveling through the filter media. The percent trapped was also found to be an inverse power function of the …

Tertiary Treatment Of Wastewater Using Oxidation Ponds, Robert A. Lauderdale, John R. Moeller, Raymond D. Hamilton
KWRRI Research Reports
The purpose of the project was to determine the value of using lagoons as a supplemental process for treating the effluent from an activated sludge wastewater treatment plant.
Only tentative conclusions can be suggested since the project was not carried to completion. It appears that lagoons will have only minimal effect on the amounts of total nitrogen and phosphate in the plant effluent, although conversion of a portion of the ammonia to nitrate can be expected. However, the concentration of ammonia was never lower than that required by EPA guidelines. Some reduction of soluble BOD appears to occur, perhaps through …

A Chronological Comparison Of The Vegetation Of Vigo County, Indiana Presettlement (1814) Versus Contemporary (1974), Ellen Oliver Donselman
All-Inclusive List of Electronic Theses and Dissertations
A study of the vegetation of Vigo County was undertaken to categorize and map presettlement and contemporary vegetation patterns, and to relate these patterns to climate, topography, soil types and land-use changes. Vigo County was divided into four major topographic units according to geography and soil types. Ttese units served as the basis for this study. The General Land Office Survey of 1814 provided data for the presettlement forest distribution. Sixteen contemporary stands were sampled to obtain data for characterization of present-day vegetation patterns. Standattributes tables and size-class tables were constructed for four contemporary and four presettlement forest units. A …
An Engineering Solution To Improve Water Quality In A Tidal Lagoon, Richard Warren Price
An Engineering Solution To Improve Water Quality In A Tidal Lagoon, Richard Warren Price
Civil & Environmental Engineering Theses & Dissertations
Rising demand for better water quality stimulated research and development of ways to improve the quality level in existing as well as proposed water systems. At present, most of the solutions focus on biological and chemical processes.
Many natural or man-made water bodies act as receivers for both point and non-point pollution sources. Employment of biological and chemical treatment has proved successful in many of these cases; however, in some cases a more natural physical solution of an engineering mode would be more desirable. A "flushing" technique using the tidal fluctuation as a driving force has been investigated and the …

Application Of Satellite Data And Lars' Data Processing Techniques To Mapping Vegetation Of The Dismal Swamp, Jeffrey Allan Messmore
Biological Sciences Theses & Dissertations
This study concerned the feasibility of using digital satellite imagery and automatic data processing (ADP) techniques as a means of mapping swamp forest vegetation. Multispectral scanner data acquired by the Earth Resources Technology Satellite (ERTS-1; renamed LANDSAT-1) was analyzed using ADP techniques developed by Purdue University's Laboratory for Applications of Remote Sensing (LARS). The site for this investigation was the Dismal Swamp, a 210,000 acre swamp forest located south of Suffolk, Va. on the Virginia-North Carolina border. Two basic classification strategies were employed in determining the vegetation mapping capability of ERTS-1 data. The initial classification utilized unsupervised techniques which produced …

Evaluation Of A Recreational Lake Rehabilitation Project, Clyde Brashier
2019: Dr. Clyde Brashier
Lake Herman, a recreational, shallow, warm water prairie lake near Madison, South Dakota drain in extensively cultivated watershed and acts as a siltation basin for a chain of four lakes. The lake is more than half silted in and since 1968 various rehabilitation efforts have been made, including the construction of silt traps and lake dredging.
Continuation of the monitoring of twenty plus chemical levels and biological populations of green algae, blue-green algae and diatoms has revealed two major changes: (1) ortho phosphate and total phosphorus levels (which increased markedly with the beginning of dredging) have decreased since dredging has …
