The Future Of Wildlife Damage Management—And Why I Want To Be A Part Of It, Scott R. Craven

Vertebrate Pest Conference Proceedings: 17th (1996)

Welcome to the 17th Vertebrate Pest Conference; THE conference for those of us who work in the field of vertebrate pest management. Actually, I prefer the term wildlife damage management to either animal damage control or vertebrate pest control, but as long as one takes a broad perspective on the definition of wildlife, there is really no difference except perhaps in perception. I do not mean to suggest that the name of the Vertebrate Pest Conference should be changed. It should not be changed. However, I do suggest that no matter what umbrella term you operate under, we are all …

Animal Rights And The Need To Understand Nature; A Debate, Walter E. Howard

Vertebrate Pest Conference Proceedings: 17th (1996)

As various societies, especially in the developed countries of the world, acquired a better life-style and standard of living, a common trend developed toward treating animals more humanely, especially the domestic ones. But the movement was too slow, and the animal rights movement captured this void and established a new ethic. Unfortunately, this was done without a full appreciation of the laws of nature. Even though this movement was clearly needed, some people have carried it too far.

Tonight, hopefully, we can have some good constructive discussions from the audience on this subject after Dr. Steve Sapontzis and I first …

Reducing Livestock Depredation Losses In The Nepalese Himalaya, Rodney M. Jackson, Gary G. Ahlborn, Mahesh Gurung, Som Ale

Vertebrate Pest Conference Proceedings: 17th (1996)

In the Nepalese Himalaya conflict with rural communities due to livestock predation to large carnivores like snow leopard, common leopard, wolf and wild dog has risen sharply in recent years. This increase is attributed to a number of factors, including implementation and enforcement of wildlife protection laws (which have permitted a recovery in carnivore numbers), the creation of protected areas (which serve as refuges from which predators can populate the surrounding area), the depletion of natural prey due to poaching and loss of habitat, and lax livestock herding practices. However, little information is presently available upon which to design remedial …

Ecological Challenges To Controlling Wild Rabbits In Australia Using Virally-Vectored Immunocontraception, C. K. Williams

Vertebrate Pest Conference Proceedings: 17th (1996)

The European wild rabbit in Australia threatens the sustainability of agriculture and conservation of native flora and fauna. Improved means of reducing these impacts are sought including effort to develop virally vectored immunocontraception (VVIC). VVIC for the wild rabbit involves complex interactions between the rabbit, myxoma virus and insect vectors of the virus. Development of the method includes not only reproductive molecular biology and genetics and manipulation of virus genetics, but also many problems in reproductive biology, ecology and population dynamics of the rabbit in diverse environments. Furthermore, epidemiology of enzootic myxomatosis, and behavior and population dynamics of several vector …

A General Protocol For Restoration Of Regulated Rivers, Jack A. Stanford, J. V. Ward, William J. Liss, Christopher A. Frissell, Richard N. Williams, James A. Lichatowich, Charles C. Coutant

United States Department of Energy: Publications

Large catchment basins may be viewed as ecosystems in which natural and cultural attributes interact. Contemporary river ecology emphasizes the four-dimensional nature of the river continuum and the propensity for riverine biodiversity and bioproduction to be largely controlled by habitat maintenance processes, such as cut and fill alluviation mediated by catchment water yield. Stream regulation reduces annual flow amplitude, increases baseflow variation and changes temperature, mass transport and other important biophysical patterns and attributes. As a result, ecological connectivity between upstream and downstream reaches and between channels, ground waters and floodplains may be severed. Native biodiversity and bioproduction usually are …

Microbial Reduction Of Crystalline Iron(Iii) Oxides: Influence Of Oxide Surface Area And Potential For Cell Growth, Eric E. Roden, John M. Zachara

United States Department of Energy: Publications

Quantitative aspects of microbial crystalline iron- (III) oxide reduction were examined using a dissimilatory iron(III) oxide-reducing bacterium (Shewanella alga strain BrY). The initial rate and long-term extent of reduction of a range of synthetic iron(III) oxides were linearly correlated with oxide surface area. Oxide reduction rates reached an asymptote at cell concentrations in excess of ≈1 x 10⁹/m² of oxide surface. Experiments with microbially reduced goethite that had been washed with pH 5 sodium acetate to remove adsorbed Fe(II) suggested that formation of a Fe(II) surface phase (adsorbed or precipitated) limited the extent of iron(III) oxide …

Results Of A Biological Survey For Leptodea Leptodoll (Rafinesque, 1820) In The Missouri River In Southeastern South Dakota, Arthur H. Clarke

United States Army Corps of Engineers, Omaha District

In late September and early October, 1995, a brail survey was carried out to determine the distribution of Leptodea leptodon (Rafinesque) in the Missouri River near Yankton and Vermillion, South Dakota. We did not find L. leptodon but useful information in three areas was nevertheless brought to light, viz. :

(1) Leptodea leptodon is unusual in that adults are deeply buried and are not available by brail. Subsequent investigations which seek to determine its abundance at its only known location in the research area, close below Gavin's Point Dam, can only be carried out with the help of a diver …

Evaluation Of The Crop Growth Component Of The Root Zone Water Quality Model For Corn In Ohio, Sue E. Nokes, Feliks M. Landa, Jon D. Hanson

Biosystems and Agricultural Engineering Faculty Publications

The Root Zone Water Quality Model (RZWQM) is a computer model developed to simulate water, chemical, and biological processes in the root zone of agricultural management systems. As of this writing RZWQM is in the beta-testing phase of development. This article reports on a parameterization and evaluation study performed in Ohio on field corn for the crop growth component of RZWQM. The generic crop growth model in RZWQM had not previously been parameterized or tested on field corn. This article reports the results of such a study. One year of data was used to calibrate RZWQM, and two additional years …

Monitoring The Dynamics Of Scaled Vehicles Using A Sonic Digitizer, Michael J. Bader, Larry G. Wells, Linus R. Walton

Biosystems and Agricultural Engineering Faculty Publications

Certain dynamic stability characteristics of an alternate method of mounting a front-end loader to a farm tractor were compared to those of a conventionally mounted front-end loader operating on a specified terrain. One objective of the study was to determine if the alternate method of mounting a front-end loader resulted in better stability characteristics and, in turn, safer operation than a conventional front-end loader. Another objective was to determine if a three-dimensional sonic digitizer could monitor the motion of the scale model tractor-loader systems accurately enough to perform a comparison between the systems. This article describes the second objective of …

Comparison Of Daily Water Table Depth Prediction By Four Simulation Models, Eric D. Desmond, Andrew D. Ward, Norman R. Fausey, Stephen R. Workman

Biosystems and Agricultural Engineering Faculty Publications

The Agricultural Drainage And Pesticide Transport (ADAPT) model was compared to the water management simulation models DRAINMOD, SWATREN, and PREFLO. SWATREN and PREFLO are one-dimensional finite-difference models while ADAPT and DRAINMOD are one-dimensional mass balance models. ADAPT, an extension of the computer model GLEAMS, also provides chemical transport information. All four models were tested against field data from Aurora, North Carolina. Observed water table depth data were collected during 1973 through 1977 from a water table management field experiment with three subsurface drain spacing treatments of 7.5, 15, and 30 m.

Both the standard error of estimate and the average …

Performance Of Vegetative Filter Strips With Varying Pollutant Source And Filter Strip Lengths, Puneet Srivastava, Dwayne R. Edwards, Tommy C. Daniel, Philip A. Moore Jr., Thomas A. Costello

Biosystems and Agricultural Engineering Faculty Publications

Vegetative filter strips (VFS) can reduce runoff losses of pollutants such as nitrogen (N) and phosphorus (P) from land areas treated with fertilizers. While VFS effectiveness is considered to depend on lengths of pollutant source and VFS areas, there is little experimental evidence of this dependence, particularly when the pollutant source is manure-treated pasture. This study assessed the effects of pollutant source area (fescue pasture treated with poultry litter) length and VFS (fescue pasture) length on VFS removal of nitrate N (NO₃-N), ammonia N (NH₃-N), total Kjeldahl N (TKN), ortho-P (PO₄-P), total P (TP), …

Variability In Volume Metering Devices, Leonard L. Bashford, Abdeljabar Bahri, K. Von Bargen, Michael F. Kocher

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The inherent variability of seed and fertilizer application from volumetric metering devices is not readily recognized. The Canadian Prairie Agricultural Machinery Institute (P AMI) suggests a maximum coefficient of variation (CV) of 15% among outlets for seeding grain or applying fertilizer. P AMI does not report down-the-row variability of individual outlets. Parameters that influence variability of volumetric measuring external fluted wheels such as rotational speed of the metering wheel, product delivery rate, seed size, and cell collection lengths were examined.

In the first study, external fluted wheel meters on four grain drills were tested for seed delivery variability for wheat …

Biodegradation Of Nonionic Surfactants And Effects Of Oxidative Pretreatment, Craig D. Adams, S. Spitzer, R. M. Cowan

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The aerobic biodegradability of nonionic, ethoxylated surfactants and model compounds, and the effect of advanced oxidation pretreatment on the biodegradability of the biorefractory surfactants were examined. Bioassays conducted using a mixed microbial seed showed that the linear primary alcohol ethoxylates, the fatty acid ethoxylates, and also polyethylene glycol were all degradable. The biomineralization of the linear secondary alcohol ethoxylate, ethylene oxide/propylene oxide block copolymer, and alkylphenol ethoxylate was observed to be inhibited to varying degrees. Additional bioassays were conducted on model compounds to examine the effect of specific structural components on biodegradability. Advanced oxidation pretreatment using hydrogen peroxide in combination …

Treatability Of S-Triazine Herbicide Metabolites Using Powdered Activated Carbon, Craig D. Adams, Tammy L. Watson

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Widespread use of s-triazine herbicides such as atrazine, simazine, and cyanazine has led to the contamination of many ground-water and surface-water supplies with the parent compounds as well as by primary metabolites (e.g., deethylatrazine, deisopropylatrazine, and deethylcyanazine). Ozonation has been shown to produce many of the same byproducts. Activated carbon adsorption has been designated by the U.S. Environmental Protection Agency as the best available technology (BAT) for the treatment of herbicides in drinking water. Little data is available, however, on the applicability of activated carbon treatment for the control of the primary degradation products of herbicides. In this study, the …

The Influence Of Acoustic Impedance Mismatch On Post-Stenotic Pulsed-Doppler Ultrasound Measurements In A Coronary Artery Model, S. A. Jones, H. Leclerc, George P. Chatzimavroudis, Y. H. Kim, N. A. Scott, Ajit P. Yoganathan

Chemical & Biomedical Engineering Faculty Publications

Acoustic impedance mismatch at the fluid-wall interface was shown to affect the spectra from an intravascular Doppler device in an in vitro model with a diameter typical of human coronary arteries. Measurements were obtained first under Poiseuille flow conditions with impedance mismatches of 0%, 7% and 12%, and then under stenosed conditions for the 0% and 7% mismatch cases. For the zero mismatch case, the Doppler spectra could be readily interpreted in terms of fluid mechanical phenomena. When mismatch was present, the spectra from Poiseuille flow exhibited multiple peaks which could not be directly related to the velocity profile. Also, …
