Controlling Wildlife Damage: Can Computers Help?, Leanne W. Las Arow

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Expert systems, a new computer field, is presented as a method to make computers more useful and professionally relevant. Expert systems technology is discussed and is demonstrated to be available and affordable. A typical wildlife damage control problem is presented: species identification of a burrowing pest from a verbal description of a mound or burrow. Development of the expert system, BURROW, is outlined in step-by-step fashion, from statement of the problem, through translating knowledge into rules, to testing and review. Emphasis is placed on encouraging others to write simple expert systems to solve routine problems.

Flocoumafen -- A New Anticoagulant Rodenticide , M. Lund

Vertebrate Pest Conference Proceedings: 13th (1988)

ABSTRACT: Flocoumafen is a new anticoagulant rodenticide with an acute toxicity between that of bromadiolone and brodifacoum. It has performed well in field tests against house mice and susceptible as well as resistant brown rat populations. Danish lab tests reveal a considerable variation in susceptibility between rodent species and indicate that practical problems in the control of certain Scandinavian bromadiolone-resistant house mouse populations may arise shortly after introduction.

Comparative Evaluation Of Tamper-Proof Mouse Bait Stations, Karl D. Morris, Dale E. Kaukeinen

Vertebrate Pest Conference Proceedings: 13th (1988)

A method for the evaluation of mouse control using tamper-proof mouse bait stations was developed and efficacy trials conducted to determine if house mice (Mus musculus) would visit and consume rodenticidal baits located within these stations. All stations were rapidly investigated by mice. Variation seen between the individual stations related to animal variation and did not appear to be related to differences in the stations themselves. Station placement was more critical to mouse investigation and subsequent bait consumption from the station than were the various features used to prohibit non-target access.

Environmental Assessment Of Las Vegas Wash And Lake Mead Artificial Wetlands Demonstration Project, John R. Baker, R. M. Gersberg, U.S. Environmental Protection Agency

Publications (WR)

The effective use of artificial wetlands for treatment of municipal wastewater is well documented; however, design and economic data for artificial wetlands development are limited (Gersberg et al., 1984a). This is due partly to regional differences in climate, soils, and vegetation and partly to the desired waste treatment. As a result, specific treatment levels and cost benefits relative to the use of an artificial wetlands for a particular site cannot be evaluated adequately without a pilot demonstration project. Las Vegas Wash receives sewage effluent from the Las Vegas metropolitan area and has been designated as a wetlands community park. Las …

Comparative Adsorption Studies On Clay Soils, Prasanna R. Mysore

Theses

An investigation has been made to study clay as sorbent in the treatment of the hazardous contaminants of potential sludge leachate emanating from industrial landfills.

Experimentally was studied six highly toxic and hazardous chemicals, which include: phenol, aniline, cyclohexanol, cyclohexanone, cresol and monochlorophenol. Vermiculate, Kaolinite, Attacote and Hectorite clays were studied as the sorbent material. Removal of organic pollutants were measured using a total organic carbon analyzer (TOC).

Results indicate that these clays can be used for some treatment of the above mentioned organic compounds. The study shows that removal of organic pollutants by clay depends on several factors, such …

Seasonal Variations In The Diurnal Characteristics Of Heavy Hourly Precipitation Across The United States, Julie A. Winkler, Brent Robert Skeeter, Paul Yamamoto

School of Natural Resources: Faculty Publications

Hourly precipitation data from 1967 to 1983 for the conterminous United States were harmonically analyzed in order to document the diurnal variability of several categories of heavy precipitation during winter, spring, summer, and autumn. The analysis revealed that the diurnal characteristics of hourly precipitation vary considerably with season, geographic region, and precipitation intensity. During winter and spring, a weak, later-morning frequency maximum prevails for the lightest (2.5-6.2 mm h-1) precipitation category. As intensity increases (to 6.3-12.6, 12.7-25.3 and >25.4 mm h-1), the amplitude of the diurnal cycle also increases, and a nocturnal maximum becomes apparent across much of the eastern …

The Vaquita: Can It Survive?, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

The vaquita (Spanish for "little cow"), or Gulf of California harbor porpoise (Phocoena sinus), has the most limited range of any marine cetacean and is probably the rarest. It has been caught incidentally in gill nets set commercially for totoaba (Totoaba macdonaldi), large fish that were over-exploited in the upper Gulf of California until they, too, were endangered. In 1975. the Mexican Government announced a total indefinite closure on fishing for totoaba, Between the time this porpoise was described as new to science (1958) and its listing by the U.S. Fish and Wildlife Service as Endangered …

13.4.1. Considerations Of Community Characteristics For Sampling Vegetation, Leigh H. Fredrickson, Frederic A. Reid

Waterfowl Management Handbook

Wetland managers often monitor marsh vegetation to determine if management goals have been met and expenditures justified. Vegetation can be monitored using indices that identify plant composition, trends in vegetative changes, or rough estimates of food production. Development of vegetation sampling protocol requires careful assessment of management goals in relation to benefits received from sampling efforts. Assessing the results of manipulations has direct management implications, whereas detailed studies that emphasize plant life histories or basic ecological investigations have less direct value. Information on plant community characteristics that will enable managers to match sampling techniques with refuge needs and the constraints …

13.4.10. Control Of Willow And Cottonwood Seedlings In Herbaceous Wetlands, Leigh H. Fredrickson, Frederic A. Reid

Waterfowl Management Handbook

Willow and cottonwood are common species in forested wetlands and occur throughout most riparian and floodplain habitats of North America. These woody species are especially common in early successional stands where seasonal flooding occurs regularly. Cottonwood and willow are often considered problem plants, because they rapidly invade wetlands dominated by herbaceous flora and can form dense, extensive stands. The shade created by these species eliminates herbaceous undergrowth, and once the sapling stage is reached, cottonwoods and willows are difficult to eradicate. Control of these species can be costly and varies considerably with latitude.

13.4.9. Preliminary Considerations For Manipulating Vegetation, Leigh H. Fredrickson, Frederic A. Reid

Waterfowl Management Handbook

A wide diversity of plants has adapted to the dynamic nature of wetlands. The continually changing floral landscape is shaped by physical or abiotic components that include climate, fire, soil, and water. Water quantity, quality, and chemistry have a dominating influence on wetlands as do factors such as hydroperiod (period when soils are saturated) and hydrological regime. Other factors that may affect the abundance, structure, and species composition of macrophytes or robust emergents are natural grazing, disease, and interspecific plant competition.

Vegetation is important to waterfowl for producing seeds, tubers, and browse; providing nest sites; and serving as substrates for …

13.1.1. Nutritional Values Of Waterfowl Foods, Leigh H. Fredrickson, Frederic A. Reid

Waterfowl Management Handbook

Over 40 species of North American waterfowl use wetland habitats throughout their annual cycles. Survival, reproduction, and growth are dependent on the availability of foods that meet nutritional requirements for recurring biological events. These requirements occur among a wide variety of environmental conditions that also influence nutritional demands. Recent work on nesting waterfowl has identified the female’s general nutrient needs for egg laying and incubation. Far less is known about nutritional requirements for molt and other portions of the life cycle, particularly those during the non-breeding season. Although information on specific requirements for amino acids and micronutrients of wild birds …

Complete Waterfowl Management Handbook

Waterfowl Management Handbook

The North American Waterfowl Management Plan, the Service's most recent mandate for management of migratory waterfowl, and recent legislation such as the Farm Bill all underscore the need for a single source of information about the management of waterfowl and their habitat. Much of this information exists in scientific papers, unpublished reports, or has never been recorded, and thus is not readily accessible by waterfowl managers. The need for a waterfowl management handbook was originally suggested to the Office of Information Transfer by personnel in the Service's north-central region. A prototype handbook was developed in 1987 and critiqued by 38 …

Small Mammal Responses To Roadside Habitat Management In South Central Minnesota, Jeffrey W. Grimm, Richard H. Yahner

Journal of the Minnesota Academy of Science

Responses of small mammals to management of roadsides in south central Minnesota were examined from August-October in 1980 and 1981. The Minnesota Department of Natural Resources established and maintained vegetation along portions of these roadsides by planting Bromus inermis and Medicago sativa as nesting cover for ring-necked pheasants (Phasianus colchicus) and with infrequent mowing. Landowners or state and county transportation departments maintained other roadside areas by frequent mowing of native vegetation. Mowing of roadsides had a negative effect on abundance of Blarina brevicauda, Peromyscus leucopus, Microtus pennsylvanicus, and Mustela erminea during both summer and autumn and on abundance of Peromyscus …

Seasonal Variations In Water Quality Parameters Of The Mississippi River Near St. Cloud, Mn, Stephen B. Ellingson, Alfred J. Hopwood

Journal of the Minnesota Academy of Science

ABSTRACT - Water quality parameters were monitored in the Mississippi River and three tributaries (Harris Channel, Watab Creek, and Sauk River) from July 1980 to April 1981. Results were correlated with water temperature and discharge to assess seasonal changes. Effects of tributary inflow on the river were determined. Planktonic carbon was estimated with the firefly luciferin-luciferase system which measures adenosine triphosphate extracted from viable cells. Particulate organic matter, planktonic carbon, and percentage viable carbon were correlated with temperature (p ~ 0.6) while nitrate plus nitrite was inversely correlated with temperature and discharge. Only the Sauk River affected the water quality …

Predicting Potential Aluminum Contamination Of Surface And Ground Waters From Acid Sulfate Enriched Drainages Emanating From Low Neutralization Capacity Watersheds, Anastasios D. Karathanasis, Vasilios P. Evangelou, Y. L. Thompson

KWRRI Research Reports

The composition of soil solutions and surface waters emanating from unreclaimed, or partially reclaimed, strip-mined watersheds with low buffering capacity in Kentucky were compared with soil solution compositions of unaffected strata in the watershed. The data suggests that almost 20 years after mining, most soil solutions and surface waters of the disturbed areas still contain high levels of undissolved Al, controlled primarily by the solubilities of a jurbanite-like material (upper limit) and alunite (lower limit).
