Coyote Depredation Control In New York - An Integrated Approach, Thomas N. Tomsa, James E. Forbes
Coyote Depredation Control In New York - An Integrated Approach, Thomas N. Tomsa, James E. Forbes
Eastern Wildlife Damage Control Conference: 4th (1989)
The New York State Cooperative Coyote Damage Control Program was established in late 1986 through a cooperative agreement between the New York State Department of Agriculture and Markets (NYSDAM) and USDA/ APHIS/ ADC in response to escalating complaints of coyote (Canis latrans) depredations on sheep from 1980-85. Ten counties with histories of and/or potential for coyote/livestock conflicts were identified and targeted for publicity and primary program emphasis. Program staff received 58 reports of coyote depredations on 182 sheep from 32 producers in the ten target counties and seven outlying counties from May 1987 through May 1989/ and verified 46 complaints …

Demonstration Electric Fences To Control Black Bear Damage To Apiaries In New York State, Janet L. Sillings, Thomas N. Tomas Jr., James E. Forbes
Eastern Wildlife Damage Control Conference: 4th (1989)
The New York State black bear (Ursus americanus) population/ approximately 4,000 animals (Clarke 1977)/ causes damage to apiaries in the Catskill/ Adirondack/ and Southern Tier regions of the state. During 1987/ 1988/ and 1989, USDA Animal Damage Control (ADC) administered a program in New York to control bear damage to apiaries. Control activities were carried out pursuant to a Cooperative Agreement between ADC and the New York State Department of Agriculture and Markets/ and were supported by matching Federal- State contributions. Program objectives were beekeeper education aimed at preventing bear damage and for the construction of demonstration temporary electric fences. …

Black Bear Damage In Virginia, Michael R. Vaughan, Patrick F. Scanlon, Sue Evelyn P. Mersmann, Dennis D. Martin
Eastern Wildlife Damage Control Conference: 4th (1989)
We examined records of black bear damage in Virginia on Shenandoah National Park, (SNP) (1979-1988) and non-Park lands (1973-1988). Mean annual damage was $5,470 on non-Park lands and $1,217 on the Park. Corn and beehives accounted for 79 percent and personal property for 72 percent of the economic loss on non-Park and Park lands respectively. Young males were responsible for most damage on non-Park lands while adults of both sexes caused most damage on SNP. Over 70 percent of bear damage incidents in the state occurred either on the Park or on land immediately adjacent to the Park. Moving bears …
Use Of Donkeys To Guard Sheep And Goats In Texas, Murray T. Walton, C. Andy Feild
Use Of Donkeys To Guard Sheep And Goats In Texas, Murray T. Walton, C. Andy Feild
Eastern Wildlife Damage Control Conference: 4th (1989)
Though livestock guarding dogs have received considerable attention in recent years, other animals including donkeys (Equus asinus) are being used to protect sheep and goats from predation by coyotes (Canis latrans). In Texas many ranchers prefer donkeys due to low cost, relatively small maintenance requirements, and compatibility with other predator control methods. This paper describes husbandry practices for use of guard donkeys and relates rancher accounts of their effectiveness in protecting sheep and goats.
Elk And Crop Damage In Pennsylvania, Gary W. Witmer, Rawland Cogan
Elk And Crop Damage In Pennsylvania, Gary W. Witmer, Rawland Cogan
Eastern Wildlife Damage Control Conference: 4th (1989)
The native eastern subspecies of elk (Cervus elaphus canadensis) was once widespread in Pennsylvania, but was extirpated from the state by 1880 (Bryant and Maser, 1982). About 177 Rocky Mountain elk (C.e. nelsoni) were re-introduced to the state between 1913 and 1926 (Sassaman, 1985). The herd increased as did crop damage complaints. Hunting seasons began in 1923 and continued until 1931. No further hunting was allowed because the herd had declined steadily. A small herd persisted in North-central Pennsylvania, in Elk and Cameron Counties. Elk sightings were rare by 1948, despite 17 years of closed hunting …
Farmland Habitat Use By Wild Turkeys In Wisconsin, R.G. Wright, R.N. Paisley, J.F. Kubisiak
Farmland Habitat Use By Wild Turkeys In Wisconsin, R.G. Wright, R.N. Paisley, J.F. Kubisiak
Eastern Wildlife Damage Control Conference: 4th (1989)
Habitat use and food habits of wild turkeys (Meleagris pallopavo) were studied during summer 1988-89 in southwestern Wisconsin in order to address growing concerns that turkeys cause considerable crop damage. Intensive telemetric monitoring in 1988 suggested that turkeys used crop fields (corn-alfalfa-oats) at a low rate compared to forest types. Brooded hens used forest habitats less and field habitats more than broodless hens and gobblers. Brooded hens appeared to use forest and crop field habitats less and non-crop fields (pasture and idle) more than expected. Broodless hens and gobblers appeared to use forest types and non-crop fields more …
Controlling Roosting Starlings In Industrial Facilities By Baiting, Bernice U. Constantin, James F. Glahn
Controlling Roosting Starlings In Industrial Facilities By Baiting, Bernice U. Constantin, James F. Glahn
Eastern Wildlife Damage Control Conference: 4th (1989)
During the winters of 1987-88 and 1988-89 a study was conducted to evaluate the potential of DRC-1339 baiting for controlling roosting European Starlings (Sturnus vulgarus) at Tennessee Eastman Company's chemical manufacturing plant in Kingsport, Tennessee. In 1987-88 Starlicide Complete® (1 %, DRC-1339 treated poultry pellets diluted 1:9 with untreated poultry pellets) was used in pre-roosting congregating areas adjacent to the roost. In 1988-89 Starlicide Complete® and DRC-1339 treated bread were used in bait containers placed in the roosting structure. Although 90 lbs of Starlicide Complete® was consumed during 1987-88, bait consumption was sporadic and no appreciable change in …

An Analysis Of The Water Situation In The United States: 1989-2040, Richard W. Guldin, Usda Forest Service
All U.S. Government Documents (Utah Regional Depository)
Several Federal agencies have historically had responsibilities for conducting assessments of the Nation's water resources. The U.S. Geological Survey (USGS), U.S. Army Corps of Engineers, U.S. Department of Agriculture's Soil Conservation Service (SCS), and U.S. Environmental Protection Agency (EPA) and its predecessor agencies, among others, have conducted studies assessing the current situation and future prospects for water in particular regions of the country. Responsibility for national water assessments was assigned to the U.S. Water Resources Council (WRC) by the Water Resources Planning Act of 1965. With the demise of the WRC in 1981, several member agencies have attempted to take …

Testing Macroevolutionary Hypotheses With Cladistic Analysis: Evidence Against Rectangular Evolution, Cliff A. Lemen, Patricia W. Freeman
Testing Macroevolutionary Hypotheses With Cladistic Analysis: Evidence Against Rectangular Evolution, Cliff A. Lemen, Patricia W. Freeman
School of Natural Resources: Faculty Publications
The properties of cladistic data sets from small monophyletic groups (6-1 2 species) are investigated using computer simulations of macroevolution. Two evolutionary models are simulated: gradualism and the punctuated-equilibrium hypothesis. Under the conditions of our simulations these two models of evolution make consistently different predictions about the distribution of autapomorphies among species. When strict stasis is enforced, the punctuated-equilibrium hypothesis predicts that the most expected number of autapomorphies per species will be zero, no matter how many characters are used in the analysis. As the number of characters used in the analysis increases, the distribution of the number of autapomorphies …

Conference organizers and/or faculty included University of Colorado School of Law professors David H. Getches, Lawrence J. MacDonnell and Charles F. Wilkinson.
Boundaries and Water: Allocation and Use of a Shared Resource is the topic of the Center's annual summer program on water this June. Most of the major rivers in the western United States are shared between two or more states. Often tribal governments play an important role in water allocation and use decisions. International considerations also may be involved in some cases. These interjurisdictional issues extend to groundwater as well as surface water.
This conference will provide the …

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
Since European settlement, human activities have totally eliminated the natural vegetation from approximately 50 percent of Nebraska’s landscape, and of that remaining most has been heavily impacted. As a result, numerous plants and animals have been extirpated from the state and many others are threatened.
The destruction of Nebraska’s natural diversity resulted in both public and private conservation groups recognizing the need for a centralized and accessible biological database for the state’s rare species and natural community types. Toward this end, the Nebraska Natural Heritage Program (NENHP) was established in August, 1987 through a cooperative effort between The Nature Conservancy …

Temporal And Spatial Patterns Of Abundance Of Age 0 Threadfin Shad (Dorosoma Petenense) In Overton Arm, Lake Mead, William Lee Pelle
Publications (WR)
Temporal and spatial patterns of age 0 threadfin shad (Dorosoma petenense) abundance and growth, in the Overton Arm of Lake Mead, were examined to evaluate the effects of resource availability on the young fish. This was part of a larger, game fishery enhancement study (Lake Mead Fertilization Project), designed to assess feasability of increasing survivorship of larval/juvenile shad by boosting phosphate levels, thereby increasing algal and zooplankton biomass, during the shad spawning period. Shad are the primary forage base for the striped bass (Morone saxatilis) and black bass (Macropterus salmoides) fisheries. Weekly samples were …
Investigation Of Major Mutagenic Substances In Airborne Particulate Matter : Biologically-Driven Analysis Of Fractions And Analysis Of Polycyclic Aromatic Hydrocarbons (Pahs) Nitro-Pahs And Other Classes Of Compounds, Jung-Hen Lwo
Theses
A modified fractionation scheme involving acid-base partitioning and silica gel column chromatography has been used as the first step in the bioassay-directed search for significant levels of mutagenic compounds in extracts of inhalable (IP10) ambient air particulates. The biologically "hot" fractions were separated and analyzed chemically or subfractionated to isolate and concentrate "hot" subfractions which were then chemically analyzed by GC/MS FTIR, and HPLC equipped with UV, Fluorescence and Photodiode Array UV detectors.
The Ames assay of mutagenicity has involved the unactivated TA98 strain of Salmonella and enzyme-activated (TA98+S9) assays. In addition, some assays have been performed in this present …
Determination Of Trace Amounts Of Lead, Cadium And Zinc In Vegetables Using Differential Pulse Polarography, Elizabeth Franca-Romitti
Determination Of Trace Amounts Of Lead, Cadium And Zinc In Vegetables Using Differential Pulse Polarography, Elizabeth Franca-Romitti
Theses
Toxic metals are present in foods to greater or lesser extention as contaminants, as a result of increasing industrialization, and associated pollution of the biosphere. Lead and cadmium are well known toxic metals which accumulate into the body causing harmful effects at low concentration levels especially in children. Zinc, on the other hand, is an essential micronutrient, but larger levels in foods can be considered toxic.
Twenty eight brands of vegetables including canned, glass packed, frozen and fresh vegetables were analyzed for Pb, Cd, and Zn, in tomatoes, carrots, mushrooms and asparagus. The technique used was Differential Pulse Polarography (DPP) …
Study Of An Analytical Method For Benzo(A)Pyrene Metabolites In Human Urine, Zheng Ouyang
Study Of An Analytical Method For Benzo(A)Pyrene Metabolites In Human Urine, Zheng Ouyang
Theses
A method developed by Becher and Bjorseth for analysis of PAH metabolites in urine was employed to investigate human exposure to benzo(a)pyrene (BaP) - an ubiquitous environmental carcinogen. Preliminary results are presented showing the relationship between exposure to BaP and urinary elimination. Although the correlation between the two variables is not statistically significant, there appears to be a positive association with selected exposure varibles such as smoking. The identification of an association may establish urinary BaP as a marker of exposure.
However, detailed study of the analytical procedure indicated that recoveries with this method were as low as 3-8% for …
Investigation Of Benzo(A)Pyrene In Outdoor Air, Indoor Air And Personal Inhalation Air, Hsiu-Wen Chen
Investigation Of Benzo(A)Pyrene In Outdoor Air, Indoor Air And Personal Inhalation Air, Hsiu-Wen Chen
Theses
The assessment of human exposure to an environmental contaminant requires the measurement of the concentrations levels present in each pathway of possible contact.
This was an investigation of human exposure to an environmental pollutant, benzo(a)pyrene, in outdoor air, indoor air and personal inhalation air samples. The analytical procedure involved extraction by ultrasonic and separation by thin layer chromatography, and detection by fluorescence. The resulting data was used to develop a profile of indoor and outdoor human exposure to B(a)P during the year.
