Development Of A Combined Quanity And Quality Model For Optimal Groundwater Management, R. C. Peralta, J. Solaimanian, S. A. Prathapar, C. L. Griffis

Arkansas Water Resources Center Technical Reports

Presented is a procedure for incorporating solute transport as linear constraints within computer models for optimizing regional groundwater extraction strategies. The MODCON modelling procedure uses linear goal programming, embedded linearized equations for flow and solute transport and a MOC simulation model. Assumed is 2D flow and solute transport and a dispersed conservative contaminant. The MODCON procedure develops steady groundwater extraction strategies that will satisfy future groundwater quality constraints while simultaneously causing future piezometric heads to be as close to current heads as possible. The procedure is applied to a 160 square mile area in southeastern Arkansas.

Land Use Effects On Ground Water Quality In Carbonate Rock Terrain, Kenneth F. Steele, James C. Adamski

Arkansas Water Resources Center Technical Reports

A control site with a natural setting and an experimental site with significant agriculture land use were studied in the Ozark Region of Arkansas in order to determine the effect of land use on water quality in a carbonate rock terrain. The vast majority of the two sites have the Boone Limestone exposed which combined with the underlying St. Joe is the major aquifer for drinking water in the area. The sites also are similar in terms of lineament patterns (number, length and orientation), soil, slope and vegetation. Ground water samples were collected primarily from springs during three seasons (late …

Social Traps And Environmental Policy, Robert Costanza

Institute for Sustainable Solutions Publications and Presentations

In recent years, scientific understanding and public awareness of environmental problems have increased tremendously. Yet our ability to manage these problems effectively has in too many cases gotten worse, not better. By studying real-world social traps and laboratory examples, we can learn effective escapes.

The Sunlight Effect On Trace Pollutants In Wastewater, Alan R. Sheu

Theses

In order to study the sunlight effect on the degradation rate of trace pollutants, ortho-cresol was selected to serve as a model compound in our studies. Solution of ortho-cresol alone, methylene blue alone, and the mixture of ortho-cresol and methylene blue were exposed to sunlight for more than four hours and aliquots analyzed with a spectrophotometer in order to follow the changes in absorption. Rate data were obtained for these three cases as a function of pH.

The results indicate that methylene blue does catalyze the degradation of ortho-cresol in the presence of sunlight with lower pH's affording higher reaction …

Indicators Of Microbial Activity In Biological Treatment Of Hazardous Wastes, Alexander Mclean Sherrin

Theses

Three methods were used to measure the activity of mixed liquor from the Livingston, N.J. municipal wastewater treatment plant on exposure to phenol. The three methods were, substrate removal rate (SRR), dissolved oxygen uptake rate (DOUR), and the dye reduction rate (DRR). Parameters from each test were compared for reproducibility and ease of determination. The SRR test gave the most reproducible results, while the DOUR test was the least reproducible. Although the reproducibility of the DRR test was close to that of the SRR test, the DRR was more time consuming and required a greater degree of expertise and training. …

Rise To Power Of Senator Joseph R. Mccarthy: Reflections Of The Cold War Mccarthy Era In American Film, Scott Lainer

Honors Theses

The common bond between much of the film industry and Joseph McCarthy was insecurity and the drive for national approval. If one grasps the specific characteristics of McCarthy the man, and the methods of these politically "inspired" movies, we can to better place the period into context and acknowledge the fact that, if the citizenry is not aware, and is again caught by an ever-building wave of trickle down sentiment, the 1950s might not prove to be an isolated period in American history. Insecurity was not a fifties novelty. It still exists, and could potentially escalate anti-Communist policy and sentiment …

Oil Spill Liability And Compensation: A Review Of The Existing Mechanisms And A Look At The Future, Gary A. Reiter

Marine Affairs Theses and Major Papers

This study provides an examination of the existing United States Federal laws and international regimes regarding oil spill liability and compensation, and the manner in which they have been implemented by regulation and policy. The presentation concludes with discussion of and arguments concerning various proposed Federal comprehensive liability and compensation legislation. Emphasis is placed on the unsuccessful legislative proposals of the 99th Congress and the effects that similar legislation, if passed by the 100th congress, may have on current response policies and Federal and state governments. In particular, the effects of the proposed legislation on state's sovereignty and response operations …

Comparison Of Littoral And Limnetic Zooplankton Communities Of Lake Mead, Patrick Joseph Sollberger

Publications (WR)

Microfaunal communities were studied in littoral (inshore) and limnetic (offshore) areas of the lower basin in Lake Mead to compare species composition and abundance between the two zones. Planktonic forms (zooplankton) dominated inshore and offshore habitats and the occurrence of littoral species was low. Therefore, high similarity in zooplankton species composition was found among all sampling stations. This was perhaps due to two main factors: (i) the physical and chemical environment among the stations were very similar and (ii) the lack of aquatic vegetation in the littoral zone reduced the occurrence of littoral species.

Although species composition did not vary …

Disturbed Alpine Ecosystems: Seedling Establishment Of Early And Late Seral Dominant Species, Jeanne C. Chambers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the effects of seedbed and seedling environment on establishment of early and late seral dominant alpine species. Species studied included late seral dominant forbs (Geum rossii, Artemisia scopulorum, and Polemonium viscosum), early seral dominant forbs (Potentilla diversifolia and Sibbaldia procumbens), a late seral dominant grass (Festuca idahoensis), and early seral dominant grasses (Calamagrostis purpurascens and Deschampsia cespitosa). Germination responses of each species to wet vs. dry cold stratification and light vs. dark conditions were investigated. No statistical differences were observed in the seed germination of early and late …

Importance Of Attractant Qualities For Improving A New Coyote Delivery System, Steven M. Ebbert, Daniel B. Fagre

Great Plains Wildlife Damage Control Workshop Proceedings

Changes in effectiveness and nontarget species selectivity of a new system for delivering ingestible substances to coyotes (Canis latrans) were examined by systematically varying odor type and quantity used to attract coyotes to the device. The new delivery system's efficacy was comparable to the M-44 in our tests in south Texas. A synthetic lure improved the effectiveness of the delivery system when applied in amounts of 0.10 cc or 0.50 cc. Varying odor type did not increase the incidence of desirable coyote behavior, such as biting, but did increase rates of visitation.

Control Of Ecosystem Processes By Prairie Dogs And Other Grassland Herbivores, James K. Detling, April D. Whicker

Great Plains Wildlife Damage Control Workshop Proceedings

Black-tailed prairie dogs in the mixed-grass prairie at Wind Cave National Park, South Dakota, create habitat patches characterized by altered species composition, lower standing crops of plants, but higher forage quality. Native wildlife species such as bison, pronghorn, and elk preferentially feed on these prairie dog colonies and likely derive nutritional benefits from doing so.

The Lure Crop Alternative, Steven D. Fairaizl, William K. Pfeifer

Great Plains Wildlife Damage Control Workshop Proceedings

Lure crops are proposed as an alternative to scaring waterfowl. The lure crop works on the principle of permitting waterfowl to feed undisturbed for the duration of the damage season in an unharvested field of their choice thereby utilizing trampled grain. Waterfowl from adjacent areas are encouraged to use the lure crop through the use of scaring devices placed in protected fields. General criteria for implementation of a lure crop project and specific criteria for lure crop purchases are presented. Factors contributing to a successful lure crop and problems which reduced lure crop effectiveness are identified. Benefit/cost analysis of lure …

Aerial Hunting Takes Sheep-Killing Coyotes In Western Montana, Guy Connolly, Bart W. O'Gara

Great Plains Wildlife Damage Control Workshop Proceedings

This paper reports limited data to document that depredating coyotes were shot from a helicopter in western Montana in 1976. Coyotes marked themselves by puncturing diphacinone-filled collars on the necks of sheep they attacked. Subsequently, 11 coyotes were shot from a helicopter on 3 ranches where collared sheep had been attacked. Six coyotes contained diphacinone and thus were confirmed as having recently attacked or fed on collared sheep.

Overwater Nesting By Ducks: A Review And Management Implications, Stephen H. Bouffard, David E. Sharp, Carol C. Evans

Great Plains Wildlife Damage Control Workshop Proceedings

Nest success of overwater duck nests is generally higher than nests in upland sites. A review of the literature indicated that the major factors limiting success of overwater nests were fluctuating water levels, nest parasitism, predation, and human disturbance. Regional patterns of the occurrence of these factors could not be discerned. General management guidelines for improved recruitment and reduced nesting female mortality are suggested.

Efficacy Of Deferred Grazing In Reducing Prairie Dog Reinfestation Rates, Kelly A. Cable, Robert M. Timm

Great Plains Wildlife Damage Control Workshop Proceedings

Population growth of black-tailed prairie dogs (Cynomys ludovicianus) was studied in 1985 and 1986 at 20 prairie dog towns on short- and mixed-grass rangeland in western Nebraska, to determine the efficacy of 2 years deferred (May 1 - Sept. 1) grazing in reducing population growth rates following population reduction. In 1985, population growth measures on deferred sites were not significantly different from grazed sites, perhaps due to drought conditions. In 1986, natality and population growth (% increase in animals) were significantly lower on deferred sites than on sites grazed by livestock. Deferred sites studied both years showed significant …

A Statistical Model Of Expansion In A Colony Of Black-Tailed Prairie Dogs, R. P. Cincotta, D. W. Uresk, R. M. Hansen

Great Plains Wildlife Damage Control Workshop Proceedings

To predict prairie dog establishment in areas adjacent to a colony we sampled: (1) VISIBILITY through the vegetation using a target, (2) POPULATION DENSITY at the colony edge, (3) DISTANCE from the edge to the potential site of settlement, and (4) % FORB COVER. Step-wise regression analysis indicated that establishment of prairie dogs in adjacent prairie was most likely to occur when an area was near a densely populated colony edge with high visibility through the vegetation.

Policy And Goals Of The U.S. Fish And Wildlife Service, Harold A. Doty

Great Plains Wildlife Damage Control Workshop Proceedings

A recent memo out of our regional office says that we shall refer to this subject as seasonal predator management. You know it covers a lot of other terms; we used to call it predator control and so on. But going back to the origins of predator management in this country, we generally think of protecting domestic crops, be it trees or grains or sheep or cattle.

If you turn in another direction and look towards Europe, you can see many centuries of involvement in use of the land. There game is a product of the land and is owned …

Prairie Dog Control—A Regulatory Viewpoint, Dennis C. Clarke

Great Plains Wildlife Damage Control Workshop Proceedings

Prairie dogs and their control are complex issues. At this conference we've heard numerous speakers discuss a wide variety of topics concerning the organism's effect on range and man's attempts to deal with those effects. It appears one could make a case for or against the prairie dog depending on his own particular situation and experience. While the organism is a natural part of the prairie ecosystem, it may not be a desirable inhabitant of a livestock producers range when its population goes unchecked.

This leads to conflict. The prairie dog becomes a biopolitical issue. On one hand it evolved …

Control Methods For Objectional Roosts Of Purple Martins, Albert E. Bivings Iv

Great Plains Wildlife Damage Control Workshop Proceedings

Multi-thousand bird roosts of Purple Martins (Progne subis) occasionally form in the South during the early summer (June-July). Nightly depositions of fecal material create considerable nuisance and potential health problems. Since they are federally protected migratory birds and have legions of bird-lovers trying to increase their populations, lethal controls are unlikely to be popular or even permitted. Control techniques including plastic netting (partial or complete exclusion), active scaring and modification of building schedules are discussed and evaluated. Plastic netting was observed to be the most successful long-term solution.
