An Ecological Analysis Of Relic Diatoms In Sediments Of Las Vegas Bay, Lake Mead, David Ross Hetzel

Publications (WR)

Relic diatoms in sediments of the inner Las Vegas Bay, near the Las Vegas Wash sewage inflow, were examined in order to assess historic trophic conditions in this area of Lake Mead. Diatom sedimentation rates and ratios of Araphidineae/Centrales (A/C) diatom groups were determined from sediment cores collected in the old wash channel 1.5 km from the sewage inflow (station 2), in a small cove 1.5 km further downstream (station 3) and in an adjacent embayment off Gypsum Wash (station 4). Diatom sedimentation rates generally increased from the bottom to the top of each core, but pronounced minima existed at …

Influence Of Photosynthetic Photon Flux Density On Uv-Binduced Photoinhibition In Soybean Leaves: Comparison Of Preconditioning And Concomitant Light Treatments, Charles W. Warner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous studies indicate that the degree of UV-Binduced photosynthetic inhibition may be highly dependent upon the photosynthetic photon flux density (PPFD, total quantum flux in the waveband 400-700 nm) incident on a plant. This study illustrates that Essex soybean leaves (Glycine max) preconditioned under high PPFD suffered less UV-B-induced photoinhibition than when preconditioned under low PPFD. However, sensitivity to UV-B increased when soybean leaves received high-PPFD as a concomitant treatment.

The relative msgnitude of UV-B-induced damage was similar for both light-limited and light-saturated photosynthesis. This probably indicates that UV-B is inhibiting fundamentally different photosynthetic processes.

Soybean leaves preconditioned …

Classification And Management Of Wetlands In The Western Kentucky Coal Field, William J. Mitsch, Robert W. Bosserman, Paul L. Hill Jr., Jan R. Taylor

KWRRI Research Reports

This is the first research report of a three-year project on wetland identification and management criteria in the western Kentucky coal field. The region is approximately 12,000 square kilometers and, due to its slight relief, contains many wetlands, some contiguous with surface coal mining operations. The overall objectives of the research project are 1) to identify, classify, and map wetlands in the western Kentucky coal field; 2) to evaluate the major biotic and abiotic factors that affect those wetlands; and 3) to develop strategies for the proper management of those wetlands.

The first report of this three-year project has involved …

Pulsed Baiting —A New Technique For High Potency, Slow Acting Rodenticides, Adrian C. Dubock

Vertebrate Pest Conference Proceedings: 10th (1982)

The disadvantages of the acute, fast-acting, rodenticides are well understood by the specialist. However, despite poison-shyness and consequent short-lived, low efficacy rodent control, many users prefer "acutes" such as zinc phosphide to "first-generation" anticoagulants of the warfarin type. The techniques necessary for efficient use of the first-generation anticoagulants are often inappropriate, particularly in agriculture. High labour and bait inputs required are unacceptable and are, together with the need for area coordinated control programs, significantly responsible for lack of widespread use of anticoagulants, even in those countries with a long history both of disastrous rodent damage to crops and rodent damage …

Commensal Rats: A Threat To Poultry Production In Nigeria, Oluwadare Funmilayo

Vertebrate Pest Conference Proceedings: 10th (1982)

Rats are now found in the majority of poultry houses in Nigeria. They usually inhabit roofs, interior of cupboards, electrical and gas appliances, holes in the soil and in walls and rubbish dumps. Extensive rat trapping yielded only two species, the cosmopolitan roof/ship rat (Rattus rattus) and the multimammate rat (Mastomys natalensis). The most outstanding types of damage, resulting in much economic loss, were the killing of chicks by decapitation and the infliction of deep wounds on adult birds. Breaking of eggs became a serious problem in a few cases. Damage to containers, bags and feed consumption was usually of …

A Review Of The Secondary Poisoning Hazard Potential To Wildlife From The Use Of Anticoagulant Rodenticides, Dale Kaukeinen

Vertebrate Pest Conference Proceedings: 10th (1982)

The utility and characteristics of the family of anticoagulant rodenticides are reviewed, including the new members difenacoum, bromadiolone and brodifacoum. General considerations are given in investigating the likelihood of nontarget poisoning with rodenticides. The literature dealing with secondary poisoning studies and concerns with the use of anticoagulant rodenticides is reviewed. The utility of laboratory toxicity data versus field-generated exposure data is compared. Considerations of secondary poisoning by anticoagulants are reviewed as regards parameters such as specific predator-prey systems, biotopes, rodenticide use patterns, and risk-benefit assessments. Finally, examples of appropriate field studies proposed to assess specific secondary poisoning risk situations associated …

Responses Of Caged Red-Winged Blackbirds To Methiocarb On Wild Rice, Daniel W. Moulton

Vertebrate Pest Conference Proceedings: 10th (1982)

Red-winged blackbirds (Agelaius phoeniceus) were offered a choice between cultivated wild rice (Zizania aquatica) treated with methiocarb and untreated wild rice. Unhulled wild rice soaked in methiocarb solution was highly effective in repelling blackbirds at residue levels <132 ppm. The responses of blackbirds to methiocarb residues <132 ppm on soaked rice were variable. Most of the blackbirds conditioned to avoid treated rice at 132 ppm of methiocarb were subsequently repelled by treated rice with residues as low as 30 ppm.

Guard Dogs And Gas Exploders As Coyote Depredation Control Tools In North Dakota, William K. Pfeifer, Michael W. Goos

Vertebrate Pest Conference Proceedings: 10th (1982)

Guard dogs and gas exploders have been successfully used in North Dakota to protect sheep from coyote (Canis latrans) depredation since the mid-1970s. They have been used in addition to other lethal and nonlethal control tools. The U.S. Fish and Wildlife Service gathered information from field testing and landowner interviews to measure their effectiveness. Guard dogs reduced the rate of depredation by 93 percent on the 36 ranches surveyed. Gas exploders deterred coyotes from depredating on 30 ranches an average of 31 days during the 1980 and 1981 grazing seasons. An increasing number of sheep producers are using these control …

The Use Of Fences For Predator Damage Control, Dale A. Wade

Vertebrate Pest Conference Proceedings: 10th (1982)

The development of exclusion fencing has been extensive in Australia in attempts to reduce losses of crops and livestock to rabbits (Oryctolagus cuniculus), dingos (Canis familiaris Var. dingo) and other species. Restrictions on other damage control methods have led to increased efforts in the United States to utilize such fences for protection of crops and livestock from dogs (Canis familiaris), coyotes (Canis latrans) and other species. Electric fences have occasionally been used to protect apiaries from black bears (Ursus americanus) and to protect some wildlife species from carnivores. Varied fence types include conventional net-wire or combinations of net and barbed …

A Comparison Of Selected Rodenticides For The Control Of The Common Valley Pocket Gopher (Thomomys Bottae), Barry R. Tickes, Lloyd K. Cheathem, John L. Stair

Vertebrate Pest Conference Proceedings: 10th (1982)

The common valley pocket gopher (Thomomys bottae) has become a serious agricultural pest in certain regions of the Lower Colorado River Basin. The mechanical burrow-builder is the most economical and effective method of controlling this pest although many growers and some researchers have reported less-than-satisfactory results when using this technique with currently available rodenticides. Six formulations of three toxicants including strychnine, zinc phosphide and diphacinone were applied with the burrow-builder to assess their efficacy. Results indicated that negligible control is achieved with 0.35 and 0.5% strychnine although these are the most commonly used formulations in Arizona. Diphacinone also produced negligible …

Teaching Vertebrate Pest Control: A Challenge To Wildlife Professionals, Robert M. Timm

School of Natural Resources: Faculty Publications

Vertebrate pest control deals with wild animals that create health hazards, damage resources, or become a general nuisance. Some people prefer the terms "wildlife damage control" or "animal damage control" because they focus on controlling damage rather than controlling animals. This is an important principle. Vertebrate animals that cause damage often have many positive values. In dealing with these situations our objective should always be to reduce or prevent damage; this does not necessarily require the killing of animals. I use the term "vertebrate pest control" because I believe it is less ambiguous than "damage control." When I call an …

Factors Influencing Development Of Cryptogamic Soil Crusts In Utah Deserts, David C. Anderson, Kimball T. Harper, Ralph C. Holmgren

Canyonlands Research Bibliography

The relation of some physical and chemical soil characteristics to cryptogamic crust development was determined from sites in semidesert regions of southern Utah. The effects of grazing on cryptogamic crust development also was examined. Electrical conductivity, percentage silt, and soil phosphorus were found to be correlated with well-developed cryptogamic crusts. Both total cryptogamic cover and the number of cryptogamic species decreased under grazing pressure. The management of rangelands, especially in arid regions, would be strengthened by understanding the role of cryptogamic crusts and considering them in range management decisions.

Impacts Of Western Coal, Oil Shale, And Tar Sands Development On Aquatic Environmental Quality: A Technical Information Matrix; Volume 1 Introduction And Instructions, Jay J. Messer, Charles I. Liff, Kurt Gernerd, Frederick J. Post

Reports

Introduction: The Upper Colorado River Basin contains vast deposits of coal, oil shale, and tar sands, which could undergo extensive development should oil prices rise or an international situation restrict oil imports. Naturally, the prospect of development of these alternative fossil fuels resources has led to concern over how extraction and conversion activities will impact environmental quality. A thorough understanding of the nature and magnitude of the resulting envionemental impacts is a necessary prerequisite, if the costs and risks of such activites are to be weighed against the economic benefits. When we set out to evaluated these costs and risks, …

Growth, Food Habits, And The Relative Effectiveness Of Stocking Rainbow Trout (Salmo Gairdneri) In South-Central South Dakota, Kenneth C. Clodfelter

Electronic Theses and Dissertations

The effectiveness of stocking rainbow trout (Salmo gairdneri) in 47 selected stock ponds in south-central South Dakota was analyzed in 1977 and 1978. Rainbow trout were captured in 31 (66.0%) ponds during the study. Twenty-five of the 31 ponds (80.6%) appeared to have excellent rainbow trout populations. Rainbow trout stocked in ponds with a resident largemouth bass (Micropterus salmoides) population had poor survival. The growth rates and condition factors for 93 and 463 rainbow trout in 1977 and 1978, respectively, were excellent. The average total length for age-groups I and II rainbow trout in 1977 was 195 and 224 mm, …

Survival, Growth, Food Selection, And Alimentary Canal Development Of Intensively Reared Walleyes And Yellow Perch, Gregg Alan Raisanen

Electronic Theses and Dissertations

Five genera of invertebrates, collected from a municipal sewage lagoon, were fed to newly hatched larval walleyes, (Stizostedion vitreun vitreun), and yellow perch, (Perca flavescens), to document survival, growth, food selection, and alimentary canal development of these fishes. Mean survival of walleyes for the 18 day period after hatching was 14.1%: mean unaccountable mortality was 43.5%. Forty-three percent of the walleyes remaining after 18 days survived an additional 32 days; mean unaccountable mortality was 33.8%. Mean daily length gain over the 50 day period was 0.8 mm/day. The cladoceran, Moina brachiate, was selected for by walleyes and yellow perch; the …
