Estimating Domestic Sheep Losses To Mountain Lions, Frederick G. Lindzey, Connie Wilbur

Great Plains Wildlife Damage Control Workshop Proceedings

Large, native-range pastures were searched for dead domestic sheep in the Southern Bighorn Mountains of Wyoming. The proportion of dead sheep that had been killed by mountain lions was 23%. Search methods, however, resulted in unequal probabilities of finding sheep that were killed by mountain lions and sheep that died of other causes.

This paper reveals the current regulatory status of 1080 and strychnine relevant to data call-in actions, administrative hearings, and litigation outside of FIFRA. All strychnine prairie dog claims are cancelled as well as all label claims requiring a tolerance. The 1080 technical is cancelled and all rodenticide uses have been issued a notice of intent to deny.

Effects Of Grackle Damage Control Techniques In Citrus On Nesting Success Of Non-Target Species, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores

Great Plains Wildlife Damage Control Workshop Proceedings

Several techniques were tested to reduce the damage caused by great-tailed grackles to citrus in the lower Rio Grande Valley of southern Texas: monofilament line, eyespot balloons, pyrotechnics, and grackle nest removal. Ten species were found nesting in the treated groves, but only the mourning dove, white-winged dove, and great-tailed grackle in significant numbers. Nesting success was not reduced significantly by any treatment but observations indicate that cannon treatments are likely to have a negative impact on overall nesting success for several species.

Controlling Raccoon Damage In Urban Areas, David G. Riley

Great Plains Wildlife Damage Control Workshop Proceedings

Raccoons have become a serious problem in many urban and suburban areas. Damage to homes and buildings as well as the spread of diseases to pets are constant problems when high raccoon populations occur. Various control methods can be implemented with positive results.

Planning For Animal Damage Control Programs Within The Animal And Plant Health Inspection Service, Philip S. Gipson, Gary P. Combs

Great Plains Wildlife Damage Control Workshop Proceedings

The Animal Damage Control Unit (ADC) and the 10 other units of the Animal and Plant Health Inspection Service (APHIS) have undergone major reorganization. Emphasis is placed on planning and risk analysis. Four levels of planning have been identified: (1) strategic planning for the Agency, (2) strategic planning for each of the 11 units, (3) program design and risk analysis, and (4) operational planning.

Seasonal Effects On Control Methods For The Great-Tailed Grackle, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores, John Hobbs, Joe Palacios

Great Plains Wildlife Damage Control Workshop Proceedings

Efficiency of methods used to control damage to citrus fruit by great-tailed grackles was found to vary considerably from season to season. From April - July, the birds congregated in small breeding colonies where they were susceptible to baiting and poisoning. From August - October, the birds could be baited in to and poisoned at watering sites. Intensive shooting and use of pyrotechnics were also used successfully at this time of year to control damage at groves with high grackle concentrations. From late October - March, birds moved over wide areas each day, and were easily frightened from groves by …

An Assessment Of The Urban Wildlife Problem, William D. Fitzwater

Great Plains Wildlife Damage Control Workshop Proceedings

Basic urban wildlife problems include: proper identification of species, shift from agrarian to urban society, different interpretations of humaneness, compassion for individual rather than a population as a whole, and public ignorance of urban pest management. Positive values are esthetics and environmental education opportunities. Negative values are disease transmission, life/injury-threatening situations, damage to buildings/other property, water structures/quality, petty annoyances, and indirect economics.

Urban Nuisance Wildlife Problems In Arizona, Rebecca L. Wright, Leonard L. Ordway

Great Plains Wildlife Damage Control Workshop Proceedings

Arizona has experienced an increase in urbanization of wildlife habitat, which has led to an urban nuisance wildlife problem. The Arizona Game and Fish Department is working to lessen the problem through public education, information packets and use of private pest control companies to remove wildlife for a fee.

Management Problems Encountered With Livestock Guarding Dogs On The University Of California, Hopland Field Station, Robert M. Timm, Robert H. Schmidtz

Great Plains Wildlife Damage Control Workshop Proceedings

Guard dogs are being promoted and utilized as effective predator damage control tools under a variety of livestock management conditions. We report our experience over 1 1/2 years with 5 dogs, primarily Anatolian shepherd and Akbash dog breeds. We discuss a number of behavioral and management problems we have encountered, some of which have not previously been reported in the literature. These include chasing vehicles and wildlife, predation on deer (Odocoileus hemionus columbianus), and incompatibility of dogs with other predator damage control methods.

Seasonal Variation In Habitat Use By Great-Tailed Grackles In The Lower Rio Grande Valley, John H. Rappole, Arlo H. Kane, Rafael H. Flores, Alan R. Tipton, Nancy Koerth

Great Plains Wildlife Damage Control Workshop Proceedings

Habitat use by great-tailed grackles was measured by performing weekly censuses of birds in 6 different habitat types: chaparral, citrus groves, feed lots, pastures, residential areas, and agricultural fields. We found that use of chaparral, citrus, and residential sites was low during the winter months, increased sharply with commencement of the nesting season in April, and declined again by October. Use of agricultural fields and pasture was irregular. Feed lot use was low during the summer, but high from October - April with October and March migration peaks. An overall sex ratio of 1.3 females/male was observed with skews from …

Recent Geologic History Of Mud-Dominated Sediments In Hillsborough Bay, Florida - Phase I Report, Gregg R. Brooks, Larry J. Doyle

Reports

The primary objective of this project, one phase of a potentially larger investigation on sediments of Hillsborough Bay, was to determine vertical distribution patterns of mud-dominated sediments. Vertical distribution patterns represent the recent geologic history of the study area. For this project the term 'recent geologic history' refers to the past several thousand years, or the period since being flooded by the Holocene rise of sea level.

Fisheries Management Paper No.23 - Management Of The South-West Inshore Trawl Fishery., N. Moore

Fisheries Management Papers

This report outlines the management plan for the south west inshore trawl fishery which already operates in coastal waters less than 200 metres deep between Guilderton and Cape Leeuwin.

This management plan takes into account these important concerns and has specifically set aside a strip of coastal area from Cape Bouvard to Cape Leeuwin for recreational usage and for protection of the benthic community, and closed the management zone north of Burns Beach to trawling.

Environmental Assessment In Bioethanol Technology Using Immobilized Yeast Cells, Minoo Kandy Zarnegar

Theses

This study is undertaken from the standpoint of water pollution evaluation in bioethanol technology, using immobilized yeast cells. Evaluation of water pollution caused by immobilized yeast fermentation is the main objective of this research.

The pollution in water remaining at the end of ethanol production, which is normally discharged in the wastewater stream, has been analyzed by the measurement of biological oxygen demand (BOD), since BOD measurement is one of the widely used parameters for water pollution evaluation. BOD obtained from produced water (stillage) was between the range of 115- 360 mg/l. The variation in BOD depended upon the removal …

Biochemical And Morphological Characteristics In Maturing Achenes From Purple-Hulled And Oilseed Sunflower Cultivars, Roger W. Bullard, Paul P. Woronecki, Richard A. Dolbeer, J. Russell Mason

United States Department of Agriculture Wildlife Services: Staff Publications

The blackbird feeding preference for sunflower oilseed variety Jacques Discovery (JD) over purple-hulled Neagra de Cluj (NdC) has been attributed to anthocyanin. To test this hypothesis, we compared biochemical and morphological properties in the achene over the maturation period. Comparisons included total phenols, anthocyanin, tannin, fat/oil, protein, nonstructural sugars, and phytomelanin contents, as well as mass properties and moisture content. Only three differences were observed: (1) Hull mass was significantly higher for NdC than JD. (2) Anthocyanins were synthesized by NdC only. (3) JD was higher in oil content. Each of these factors may play a role in reduced preferences …

The Use Of Banding Recovery Data To Estimate Dispersal Rates And Gene Flow In Avian Species: Case Studies In The Red-Winged Blackbird And Common Grackle , William S. Moore, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Dispersal resulting in gene flow strongly affects the evolution of genetic structure in populations. This report describes statistical estimators of dispersal parameters based on USFWS banding recovery records. Finite-area studies of avian species yield estimates of root-mean-square (RMS) dispersal along a transect of about 1 km per generation. In contrast, estimates of RMS dispersal for the Red-winged Blackbird (Agelaiusp hoeniceus) and Common Grackle (Ouiscalus auiscula), based on USFWS banding recovery records, are 94.6 and 111.4 km per generation, respectively. Distributions for both species are extremely leptokurtic, and confidence intervals based on jackknife statistics are large because the estimators are sensitive …

The Metropolitan Wastewater Treatment Plant And The Mississippi River: 50 Years Of Improving Water Quality, D. Kent Johnson, Paul W. Aasen

Journal of the Minnesota Academy of Science

ABSTRACT-The Metropolitan Waste Control Commission and its predecessors have operated the Metropolitan Wastewater Treatment Plant on the Mississippi River at St. Paul, MN, for the past 50 years. Analysis of water quality data collected over the past 60 years shows a general improvement of water quality as the waste treatment process has been upgraded. In 1926, dissolved oxygen ranged from <1 mg/L to 2 mg/L in the river reach from St. Paul to Lock and Dam 3 (August mean values). In 1987, dissolved oxygen values in the same area were 7 mg/L or greater. The drought of 1988 produced severe low flow conditions in the Mississippi River, but dissolved oxygen values continued to meet or exceed the 5 mg/L water quality standard. Biological sampling in 1926 and 1959 showed an absence of clean water organisms. Biological sampling in 1985 showed an abundance of clean water organisms. The most dramatic evidence of this resurgence is the reappearance of the Hexagenia mayfly in St. Paul after a 50 year absence. The water quality improvements in the Mississippi River correlate directly with improved treatment plant processes, particularly the current advanced secondary treatment facility, and with improved waste control throughout the Minneapolis/St. Paul area.

A Site-Specific Need Assessment For Ocean Incineration At The North Atlantic Incineration Site (Nais), Lynne H. Macdonald

Marine Affairs Theses and Major Papers

This thesis examines the problems of hazardous wastes in the United States-and the problems their disposal present, in particular. Ocean incineration, one of the very few methods available to destroy many highly toxic wastes, is presented as a viable, necessary means to destroy liquid organochlorine wastes. Next, the international and federal regulations governing ocean incineration and the current status of ocean incineration in the United States are reviewed. A site-specific assessment for determining the need for ocean incineration is developed as an alternative to the two currently contended approaches (nationwide versus permit-by-permit need assessments). This site-specific need assessment evaluates the …

The South Pacific Nuclear Free Zone Treaty, Susan Ware

Marine Affairs Theses and Major Papers

The South Pacific Nuclear Free Zone Treaty was opened for signature on August 5, 1985, on the 40th Anniversary of the Bombing of Hiroshima. The Treaty prohibits Party states from controlling or assisting in the manufacture of nuclear explosive devices and from allowing devices not in their control stationing within their territory or land space. The Protocols to the Treaty enjoin the nuclear weapon sates and the states with territories within the Zone to adhere to the principles of the Treaty and to refrain from control or use of any nuclear explosive devices within the Zone. The principle concern of …

Formulation Of A Management Scheme For The Swordfish Fishery Of The Eastern Caribbean, Harold F. Upton

Marine Affairs Theses and Major Papers

During the 1983 season, two U.S. longline vessels initiated the first attempts at the commercial exploitation of swordfish in the Eastern Caribbean. In 1986, the number of U.S. vessels participating in the fishery surpassed 40 with landings of nearly two million pounds per season. The sudden influx of participants and technology to the region has resulted in a variety of user conflicts and associated policy issues. Major areas of concern involve the conservation of a heavily exploited resource and the distribution of benefits which accrue from resource exploitation among the resource-adjacent island states and U.S. fishing operations. This study examines …

Stormwater Quality Management In Rhode Island, Elizabeth A. Scott

Marine Affairs Theses and Major Papers

This study documents the threat that uncontrolled "urban" stormwater runoff poses to surface water quality and the inadequacy of existing regulations governing land use development in preventing further water quality degradation resulting from "urban" runoff. The study applies recent research findings from the Nationwide Urban Runoff Program and the experience of other state regulatory programs in evaluating management alternatives and proposing a strategy for Rhode Island. The documented impacts of "urban" stormwater runoff on water quality, including excesses in criteria for copper, lead, and coliform, and eutrophication, support the need for stormwater quality management. This need is made more evident …

Sewage Discharge By Recreational Boats In R.I. Coastal Waters, Maureen E. Eldredge

Marine Affairs Theses and Major Papers

Federal legislation regulating sewage from recreational boats has existed since 1972 (The Clean Water Act). Since that time the regulations have failed to prevent untreated sewage from boats from being discharged into the Nation's waterways. This has caused conflicts over water quality, particularly in shellfish growing areas. The regulatory system which exists to regulate sewage from recreational boats was analyzed for nine sources of possible regulatory failure. Seven of the nine were found to be operating. They include, lack of technology, lack of enforcement, lack of issue salience, negative attitudes on the part of the boaters, the economics of compliance, …

Antarctic Peninsula Mysticete Whales: Conservation And Research, Gregory Schofield Stone

Marine Affairs Theses and Major Papers

This paper reports original research from two recent studies in the Antarctic Peninsula area, reviews past sighting information and policies affecting mysticete whales, and recommends future research. Due to poor management by the International Whaling Commission, mysticete whales are among the most severely depleted species groups in the Antarctic. The combined total Antarctic harvest from 1920 to 19867 for blue Balaenoptera musculus, fin B. physalus, sei B. borealis, minke B. acutorostrata and humpback Megaptera novaeangliae whales was over one million animals. The effect of this hunting pressure is the dominant factor determing the present status of Antarctic …

Leschenault Peninsula : A Study Of Land Resources And Planning Considerations, Veronica P M Oma

Resource management technical reports

Leschenault Peninsula is a fragile coastal dune barrier north of Bunbury, Western Australia. Most of the landforms are highly, or potentially highly, unstable and are not capable of sustaining tourism uses other than walking tracks. Minor areas close to Leschenault Inlet are more stable and could be developed for a range of tourism uses including accommodation and day tripper facilities. However, much of the Peninsula is highly degraded and susceptible to wind erosion, while disposal of acid-iron rich li id effluent from the Laporte (SCM) works in lagoons located within the dunes, has contributed to the visual degradation of the …

Riparian Plant Water Relations Along The North Fork Of The Kings River, California, J. L. Nachlinger, S. D. Smith, R. J. Risser

Life Sciences Faculty Research

Plant water relations of five obligate ripar-ian species were studied along California's North Fork Kings River. Diurnal stomatal conductance, transpi-ration, and xylem pressure potentials were measured throughout the 1986 growing season and in mid-season in 1987. Patterns were similar for all species although absolute values varied considerably. Maximum stomatal conductance occurred early in the day and season during favorable environmental conditions and decreased as air temperature and the vapor pressure difference between the leaf and air increased. Maximum transpiration rates occurred in mid-morning and mid-summer resulting in estimated daily water losses per unit sunlit leaf area of 163-328 mol H2O …

Water Erosion Of Farmland In 1988, K J. Bligh

Journal of the Department of Agriculture, Western Australia, Series 4

Widespread heavy rains in WesternAustralian agricultural areas in 1988 caused severe water erosion, much of which could have been avoided by minimum cultivation and lower stocking rates.
