Coydogs In Nebraska, Brian R. Mahan

Great Plains Wildlife Damage Control Workshop Proceedings

Skulls of 44 suspected coyote (Canis latrans) x dog (C. familiaris) hybrids, "coydogs" were collected in Nebraska from September 1975 through April 1976. Each skull was compared statistically with skulls of known coyotes, dogs, coydogs, gray wolves (C. lupus), and red wolves (C. rufus) for identification. Thirty-two males were identified as: 5 coyotes, 2 dogs, 25 coydogs; 12 females were identified as: 4 coyotes, 2 dogs, 6 coydogs. Three concentrations of hybrids were located in southeastern Nebraska.

Prairie Dog Management: Educational Assistance To Local Governmental Units, Edward K. Boggess

Great Plains Wildlife Damage Control Workshop Proceedings

There is a long history of involvement between Kansas State University (formerly Kansas State Agricultural College) and township governmental units regarding control of prairie dogs. In 1901 and 1903, the Kansas legislature passed laws authorizing townships to conduct prairie dog control programs and providing funds for the College to conduct experiments on methods of controlling prairie dogs and gophers. The acts also directed the College to procure and furnish to the townships the proper prepared materials for prairie dog control. The Experiment Station began supplying strychnine baits in January of 1902 and continued this practice until 1970.

Predation On Big Game And Its Management, Samuel L. Beasom

Great Plains Wildlife Damage Control Workshop Proceedings

This paper summarizes information from the literature and personal observation to present an overview of the effects of predators on big game populations. Specifically it examines control of prey populations, culling of inferior prey, and stimulation of prey productivity. Food habit investigations were omitted because of the impossibility of evaluating the impact of predation by this approach because of a lack of population data.

Hydraulic Resistance Of Grass Media On Shallow Overland Flow, David K. Tao, Billy J. Barfield, Austin E. Lyons

KWRRI Research Reports

Simulated dense vegetation with random blade arrangements and different blade flexibilities were used to determine the hydraulic properties of flow of small, non-submerging depths. With the water flowing among the randomly patterned vegetation blades, drag resistance becomes the dominant force that retards the flow. An equation of flow was established based on the momentum balance in the system. Experimental results were used to determine the coefficient of blade resistance, R_D, and plotted in terms of blade width and flow depth Reynolds number respectively.

A Seasonal Study Of Phytoplankton Composition Abundance And Productivity In Back Bay, Virginia, Robert Ringgold Comegys

Biological Sciences Theses & Dissertations

Phytoplankton samples were collected monthly (August 1974-June 1975) at two stations in the Back Bay system of southeastern Virginia. Measurements of phytoplankton productivity and potentially influencing environmental parameters (water and air temperature, turbidity, depth, pH, salinity, dissolved oxygen) accompanied sample collections. A total of 106 phytoplankton species, representing six algal divisions and 54 genera were identified. Cyanophyta species were dominant at both stations in the warmer months of August, September, October, and June, and in April at one station only. In all remaining months, Chlorophyta species were dominant, indicating a seasonal shift in phytoplankton composition during winter and spring. The …

An Investigation Of Using Derivation Reaction Gas Chromatography To Measure Anionic Water Quality Parameters, Richard H. Hanson

Arkansas Water Resources Center Technical Reports

A new analytical method has been developed which provides researchers with another way to measure orthophosphate content in aqueous samples. The reaction gas chromatographic system was capable of analyzing orthophosphate in the range from 0.25 - 5.0 micrograms of P in 50 microliters of aqueous sample. Flame ionization proved to be the most successful detector. The primary advantage of this technique was the small volume of sample required.

Optimal Systems Of Storm Water Detention Basins In Urban Areas, D. K. Mynear, C. T. Haan

KWRRI Research Reports

Flood retention basins are commonly used in urban areas to reduce the impact of urbanization on downstream flooding. When more than a few acres are developed, systems of retention basins are often required. A procedure has been developed whereby the optimum (least cost) system of basins can be determined to meet a given downstream flow requirement. The method considers several design options including basins on all subwatersheds, basins on only some of the subwatersheds, basins of various sizes and basins with various stage-discharge characteristics. The procedure has been developed in the form of a computer program to aid the designer …
