The Aquatic Macroinvertebrates Of The White River National Wildlife Refuge, Steve W. Chordas Iii, George L. Harp

Arkansas Water Resources Center Technical Reports

The primary purpose of this study was to survey the diversity of the aquatic macroinvertebrates of the White River National Wildlife Refuge (WRNWR). Determining relative abundance and distributional and seasonal patterns were secondary objectives. No comprehensive investigations of the WRNWR aquatic macroinvertebrates had been conducted previously, and it was hypothesized that this relatively undisturbed area may serve as a refugium. Further, this study provides base line data by which management programs can be composed. Thirty sampling stations were established within the WRNWR. Samples were collected from north to south at a basic rate of five stations per month. Revisit collections …

Water Quality As Affected By Pesticides In Rice Production, W. G. Johnson, T. L. Lavy, J. D. Mattice, B. W. Skulman, R. E. Talbert, R. J. Smith

Arkansas Water Resources Center Technical Reports

Studies were conducted to determine the environmental persistence of the rice pesticides triclopyr, 2,4-D, benomyl and quinclorac. Triclopyr half-lives ranged from <7 d to >100 d depending on depth within the soil profile and clay content. Triclopyr persistence increased as depth within the profile increased and clay content increased. The benomyl metabolite MBC was present at greater than 50% of the initial amount after 9 months in the field. In simulated carryover field studies quinclorac exhibited the greatest potential for injury to subsequent rotational crops. Cotton and soybean growth was reduced when planted at four weeks after quinclorac application. The adsorption of triclopyr …

Determination Of The Abient Toxicity Of The Tailwater Of Nimrod Lake, John T. Knight

Arkansas Water Resources Center Technical Reports

The objective of this research was to determine if ambient toxicity exists in the receiving stream below a reservoir in which water from the hypolimnion is released. The Ceriodaphnia 7-day test was utilized to determine if toxicity existed. This test is routinely used in the monitoring of municipal and industrial effluent. It has also been utilized in determining if ambient toxicity exists within receiving streams. Nimrod Lake is a flood control impoundment on the Fourche LaFave River in west central Arkansas. The literature suggest that during stratification the hypolimnetic release contains high levels of iron, manganese, ammonia and sulfide during …

Selecting And Developing Reliable Bore Sites In The Eastern Wheatbelt, Richard George

Bulletins 4000 -

In the Western Australian wheatbelt, groundwater supplies contribute about 40 per cent of the on-farm livestock requirements and occasionally domestic water supply systems. The first part of this Bulletin comments on sites suitable for both high yielding bores and also those which yield water suitable for livestock. The second part outlines techniques for constructing and developing a bore. Throughout this Bulletin livestock quality water, for adult sheep, is defined as groundwater of less than 12,000 mg/L (or 850 grains per gallon) which has not been subject to localized pollution. For other livestock, the maximum salinities range from 2,600 mg/L for …

Acid Recovery Of Cadmium And Lead From Immobilized Activated Sludge Used To Biosorb Metals, Chandrakanth Hartman

Theses

A study of the adsorption and subsequent desorption of heavy metals using various concentrations of hydrochloric acids has been performed.

To accomplish this task, the following areas were investigated : immobilization of the sludge, adsorption of heavy metals, various concentrations of acid used as stripping agents, examination of the relative fractions of heavy metals obtained using various stripping agents, and the actual concentration of the acid at a particular fraction.

It was observed that water helps in extraction of cadmium to a certain extent, but lead cannot be extracted with water. Also, water mixed with dilute hydrochloric acid is more …

Biodegradation Of Styrene In A Recirculation Reactor Using Immobilized Activated Sludge, Shreyans Dilip Shah

Catalytic Oxidation Of Trace Concentrations Of Chlorinated Hydrocarbons Over 1.5% Platinum On Alumina/Monolith, Yi Wang

Theses

The catalytic oxidation of chlorinated hydrocarbons CH₂Cl₂ (DCM) and C₂HCl₃ (TCE) was investigated over a 1.5% Pt on Al2O3/monolith at 150 to 450°C. The studies were conducted at space velocities from 1,000 v/v/hr to 30,000 v/v/hr. Chemical equilibrium calculations showed the potential conversion and products distribution. The reactivity and selectivity for destruction of these compounds with air over Pt catalyst were evaluated experimentally. This research was conducted in a tubular reactor system with associated feed and product flow measuring equipment. Feed and product streams were analyzed using gas chromatography (GC) with ECD, FID and …

Microwave Treatment Of Hazardous Wastes : Chemical Fixation Of Insoluble Non-Volatile, Chemically Non-Reactive Organics In Soil, Naihong Zhu

Theses

Microwave treatment of hazardous wastes like dioxin-contaminated soil potentially fills a great need for a remediation technology which potentially can be applied in-situ: the EPA has concluded from a risk assessment study that it is the excavation and transportation of such wastes that poses the greatest risk. Studies have been carried out on a surrogate for dioxin, namely, 9,10-anthraquinone because it has similar chemical and physical properties but it is not toxic. It was found in microwave treatment studies that, at temperatures attainable in-situ, anthraquinone became non-extractable. A model was proposed which postulated that as water was removed from soil …

Wildlife Damage Management In The 90s—Does The Professional Fit The Profession?, Jay B. Mcaninch

Great Plains Wildlife Damage Control Workshop Proceedings

A recurring theme at animal damage conferences has been the lack of interest in, and recognition of, animal damage management or problem wildlife manage-ment as an important topic in the wildlife profession (Timm 1982; Berryman 1983, 1989; Jones 1983; Miller 1987; San Julian 1989; Schmidt 1989a). This concern has been raised by Animal Damage Control (ADC) workers in urban, suburban, agri-cultural and forested systems and, in fact, can be heard in nearly any landscape in which wildlife are in conflict with people's use of the land. While the scope of these issues involves the largest potential constitu-ency the wildlife profession …

Utah State University's Academic Program In Wildlife Damage Management, Michael R. Conover, Raymond D. Dueser, Frederick F. Knowlton, Joseph A. Chapman

Great Plains Wildlife Damage Control Workshop Proceedings

Every wildlife species has positive values or benefits it provides to society. Some people enjoy hunting, while others enjoy watching and hearing wildlife; still other people derive pleasure simply knowing animals exist free from human dependency (King 1947, Ehrenfeld 1976, Steinhoff 1978). Each species also has negative values (Decker and Purdy 1988) associated with adverse impacts, such as property damage, damage to agricultural crops, predation on other valuable species, or simply being a nuisance. For any location and point in time, the net value of any wildlife resource is the sum of all its positive and negative values. The goal …

What's In A Name?, Robert S. Cook

Great Plains Wildlife Damage Control Workshop Proceedings

Communication is a vital part of this complex world in which we live. Even with the vast vocabulary that has evolved throughout recorded history, we still often find difficulty in expressing ourselves. As receivers of information, we struggle to grasp what the other person is trying to say. Also, when we speak to others, we struggle for the right words to use so that we can convey to that person exactly what we mean. The words we use and how we use them are very important to us as we communicate with each other. We have all experienced a time …

Social, Political, Legal, And Ethical Aspects Of Wildlife Damage Management, Robert H. Schmidt, Terrell P. Salmon

Great Plains Wildlife Damage Control Workshop Proceedings

Wildlife damage management practices are more influenced by our social environ-ment today than in any other period during history. Change is clearly in the wind, and the scope and range of that change will be defined by the social, legal, political, and ethical constraints determined by all seg-ments of society. By defining the decision-making environment, however, management decisions can be made with a clearer under-standing of potential ramifications and, hopefully, a refinement of uncertain princi-ples that influence management decisions affecting natural resource use (Holling 1978).

Educating People About Wildlife Damage, Jeffrey S. Green

Great Plains Wildlife Damage Control Workshop Proceedings

Managing the damage that species of wildlife cause to human-owned resources is a legitimate area of specialization in the field of wildlife management. In recent years, wildlife damage management, particularly the Federal government's Animal Damage Control (ADC) program, has come under increased scrutiny and opposition. Reasons for the increased focus on ADC are varied but no doubt center on the fact that some of ADC's activities involve killing animals. Groups opposed to ADC have used the media to gain a following, but the glimpses of ADC they have shown to the public are rarely balanced or objective. Stories usually focus …

Effects Of A Visual Barrier Fence On The Behavior And Movements Of Black-Tailed Prairie Dogs, Nancy S. Foster-Mcdonald, Scott E. Hygnstrom

Great Plains Wildlife Damage Control Workshop Proceedings

Prairie dogs prefer an open view of their surroundings and may abandon an area with visual obstructions. We examined the effects of a visual barrier fence, which had a see-through visibility of 60%, on the foraging, vigilance, and aggressive behaviors of adult female black-tailed prairie dogs (Cynomys ludovicianus) in central Nebraska. We expected animals near a visual barrier to spend more time in vigilance and less time foraging. Adult female prairie dogs exposed to a visual barrier spent a greater amount of time foraging and less time in a headbob position than those not exposed to a fence (P = …

Burrowing Owl Ecology And Suggestions For Minimizing Impacts Of Prairie Dog Control, Martha J. Desmond, Julie A. Savidge

Great Plains Wildlife Damage Control Workshop Proceedings

Burrowing owls (Athene cunicularia) are declining throughout much of their range. They were placed on the Audubon Society's Blue List in 1971 and were listed as a Species of Special Concern in 1986. Little information exists on burrowing owl population sizes and causes of population declines appear to be mostly speculation. Although considerable research has been done on burrowing owls in the Western United States, relatively little is known of the burrowing owl population in the Great Plains. In the Great Plains, burrowing owls will nest in abandoned badger (Taxidea taxus) burrows but are most commonly associated with black-tailed prairie …

Reducing Nuisance Canada Goose Problems Through Habitat Manipulation, Michael R. Conover

Great Plains Wildlife Damage Control Workshop Proceedings

Urban populations of Canada geese (Branta canadensis) cause considerable problems when large numbers congregate in parks, playing fields, and backyards. In most cases, geese are drawn to these sites to feed on the lawns. I tested whether geese have feeding preferences for different grass species. Captive Canada geese preferred Kentucky bluegrass (Poa pratensis) and disliked tall fescue (Festuca arundinaceae) over colonial bentgrass (Agrostis tenuis cv. Highland), perennial ryegrass (Lolium perenne), and red fescue (Festuca rubra). They refused to eat some other ground covers such as pachysandra (Pachysandra terminalis) and English ivy (Hedera helix). These results suggest that goose numbers at …

Environmentalism And Animal Welfare: Cornerstones Of Wildlife Damage Management, Rick D. Owens

Great Plains Wildlife Damage Control Workshop Proceedings

There are two issues which each of us, personally and as professional wildlife biologists, share a belief in, and which are essential to the conduct of our day-to-day wildlife management activities. Unfortunately, because of associated negative implications, we have failed to appropriately acknowledge and receive credit for our concerns regarding these issues. These are the issues of environmentalism and animal welfare. This discussion will serve to clarify what these terms should mean to us, why they should be considered cornerstones of wildlife damage management, and the actions we must take in addressing these issues. It is imperative that we become …

A Matter Of Perspective, Dale Rollins

Great Plains Wildlife Damage Control Workshop Proceedings

Abstract: One's views regarding the relative or absolute merits of predators are largely a matter of individual perspective. Surveys have documented that rural and urban residents differ greatly on the scope of predator problems and methods for predator management. In order to educate the urban public, a broadcast quality videotape was produced that outlines the controversy surrounding predator control in general, and coyote control in particular. This video examines the coyote from the perspective of a sheep rancher, an "environmentalist," and an ecologist. The intent of the program is to neither praise nor condemn the coyote, but to provide the …

An Update On The Revision Of The Handbook, "Prevention And Control Of Wildlife Damage", Scott E. Hygnstrom, Robert M. Timm, Gary A. Larson

Great Plains Wildlife Damage Control Workshop Proceedings

Wildlife species have an important role in our environment and they provide many recreational, economic, and aesthetic benefits. Management of these species is necessary, however, when they cause damage to agricultural, industrial, and natural resources, and threaten personal property, public health, and safety. Published estimates indicate that commensal rodents, field rodents, and predators combined, cause >$2 billion in damage in North America annually. Because of the social and economic impacts of wildlife damage, there is a need for up-to-date information on the prevention and control of wildlife damage for producers, resource managers, administrators, and the public. The book, "Prevention and …

Damage Due To Scent Marking By Eastern Gray And Fox Squirrels, John L. Koprowski

Great Plains Wildlife Damage Control Workshop Proceedings

The stripping of bark by eastern gray squirrels (Sciurus carolinensis) is a serious problem in England with 50 to 100% of the trees damaged in some locations (Shorten 1957). The economic consequences of such damage have resulted in much research (Kenward 1982, 1983; Kenward and Parish 1986); squirrel-induced damage to trees also occurs in North America (Allen 1943, Brenneman 1954) but is rarely of the magnitude observed in England. At least 10 hypotheses (reviewed by Kenward 1983) have been suggested to account for bark-stripping damage including: 1) reduction of tooth wear; 2) uncontrolled gnawing reflex; 3) source of nesting material; …

The Denver Wildlife Research Center: An Update, Richard D. Curnow

Great Plains Wildlife Damage Control Workshop Proceedings

The Denver Wildlife Research Center (DWRC) has progressed as part of the U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) in its capability to support the APHIS Animal Damage Control (ADC) program and provide the agency and the public with expanded knowledge and new or alternative tools to reduce wildlife conflicts with agriculture and other human endeavors.

The Handbook Of Wildlife Depredation Techniques: A Synopsis, Tim Fagan, John Demaree

Great Plains Wildlife Damage Control Workshop Proceedings

In 1979, the Game Division Administration of the Wyoming Game and Fish Department (WGFD) appointed John Demaree and Tim Fagan to develop a handbook that would address the ever increasing problem of wildlife depredation. Field personnel were often times at a loss on how to deal with or evaluate the assorted types of damage situations they were encountering. Because Wyoming requires landowners to be reimbursed for damage done by big and trophy game and game birds to their crops and livestock, an evaluation and techniques handbook was desperately needed. The initial handbook, completed in January 1981, was 74 pages, and …
