Fisheries Report No 74 - Marine Resources Map Of Western Australia- Part 2 - The Influence Of Oil On Marine Resources And Associated Activities With An Emphasis On Those Found In Western Australia, H. E. Jones
Fisheries Research Reports
Part 1 of the text accompanying the marine resources maps dealt with the resources and the morphological, hydrological and meteorological characteristics of the Western Australian coastal environment. This subsidiary part is concerned with the effects of oil on marine resources and associated commercial and recreational activities.
Accounts of oil on the seas due to natural seepages appeared in Europe in the sixteenth century on the return of Spanish and Portuguese ships from voyages to the Americas. One of the earliest reports of oil pollution from a man-made source was in 1754 when leakages from wooden petroleum barges were prevalent in …
Fracture Detection In A Volcanic Oil Reservoir Using Discriminant Analysis Of Well Log Data, Joseph William Cross
Fracture Detection In A Volcanic Oil Reservoir Using Discriminant Analysis Of Well Log Data, Joseph William Cross
OES Theses and Dissertations
A new method of detecting fractures using well logs is presented. The technique uses discriminant analysis to distinguish fractured from unfractured reservoir rock and was developed for the volcanic pay zone of Jatibarang oilfield, West Java, Indonesia.
The a priori information required to derive the discriminant function was provided by 22 wells known to penetrate intervals of either fractured or unfractured volcanics. The samples consisted of these 22 intervals digitized in one-meter increments (1256 meters total thickness). The discriminating variables were the petrophysical measurements made by 10 different types of well logs.
Discriminant analysis correctly classified 94.2% of the total …

Hydraulic Design Algorithms For Upgrading And Enhancing Water Distribution Systems, Don J. Wood, William T. Gilbert
Hydraulic Design Algorithms For Upgrading And Enhancing Water Distribution Systems, Don J. Wood, William T. Gilbert
KWRRI Research Reports
The primary objective of this work was to develop algorithms for directly determining design characteristics for effectively enhancing, modifying or adding to existing water distribution systems. This is accomplished by modifying the basic hydraulic network equations to explicitly determine required design parameters to just meet specified conditions. Initially work was completed on directly determining pipeline diameters and directly determining pipeline and network resistance characteristics. This work was published in technical journals and established the feasibility of the approach but did not demonstrate the scope and versitility of the proposed approach. In this report a general approach is developed and tested …
The Reclamation Of Boston Harbor: A Scientist's Perspective, Gordon T. Wallace Jr.
The Reclamation Of Boston Harbor: A Scientist's Perspective, Gordon T. Wallace Jr.
New England Journal of Public Policy
A major effort, costing in the neighborhood of $2 billion, is under way to restore the environmental quality of Boston Harbor. While Boston Harbor is unquestionably one of the most polluted urban estuaries in the world, it is also one of the least understood with respect to the basic physics, chemistry, and biology involved. This information is essential for the purpose of identifying processes that control the transport, effect, and fate of contaminants entering the estuary. Failure to obtain this information may lead to continued inappropriate and unnecessarily expensive solutions to a complex environmental problem. An effective solution will require …

Characterization Of Microorganisims After Feeding With Phenolic Compounds : Comparing A Domestic Sludge To An Industrial Sludge, Dianne Adamowitz
Characterization Of Microorganisims After Feeding With Phenolic Compounds : Comparing A Domestic Sludge To An Industrial Sludge, Dianne Adamowitz
Theses
This study examined the effects of phenolic compounds on the populations in mixed liquors obtained from two very different treatment plants: the Passaic Valley Sewerage Commissioners plant in Newark, and the Livingston, NJ municipal treatment plant. The dominant organisms were identified initially and after ten days exposure to phenol (100 ppm), and either 2-chlorophenol (20 ppm) or 2,6-dichlorophenol (10 ppm) in aerated batch reactors.
Results confirmed the remarkable similarity between the two mixed liquor populations, in spite of the significant differences in the operation of the two treatment plants.

Secondary Toxicity Of Coyotes Killed By 1080 Single-Dose Baits, Richard J. Burns, Guy E. Connolly, Iwao Okuno
Vertebrate Pest Conference Proceedings: 12th (1986)
Carcasses and viscera of coyotes poisoned by Compound 1080 (sodium fluoroacetate) in single-dose tallow baits (SDBs) were fed to 3 coyotes, 3 domestic dogs, 4 striped skunks, and 15 black-billed magpies to determine if these species would be poisoned secondarily. Test subjects received no food other than tissues from poisoned coyotes for periods of 14 to 35 days. Total amounts of contaminated coyote tissues consumed by dogs, coyotes, skunks, and magpies, respectively, averaged 67, 152, 117, and 371% of body weight. Except for one skunk that refused to eat, no mortalities occurred and no evidence of poisoning was seen. The …

Evaluating A Pop-Up Scarecrow Coupled With A Propane Exploder For Reducing Blackbird Damage To Ripening Sunflower, John L. Cummings, C. Edward Knittle, Joseph L. Guarino
Vertebrate Pest Conference Proceedings: 12th (1986)
A combination Purivox® Double-John carousel propane exploder and CO2 pop-up scarecrow operated in synchrony was evaluated in five ripening sunflower fields in 1981 and 1982, respectively, near Devils Lake and Westhope, North Dakota. In each field, this treatment was evaluated in an alternating off-on sequence of 5-day intervals for a period of 20 days. In 1981, devices were deployed at one unit per 8 to 10 acres and in 1982 at one unit per 4 to 6 acres. The degree of effectiveness for reducing bird damage in three of five fields that met selection criteria ranged from 71 to 87% …
A Review Of Brodifacoum Efficacy In The U.S. And Worldwide, Dale E. Kaudeinen, Michael Rampaud
A Review Of Brodifacoum Efficacy In The U.S. And Worldwide, Dale E. Kaudeinen, Michael Rampaud
Vertebrate Pest Conference Proceedings: 12th (1986)
It was just over 10 years ago with the paper by Hadler and Shadbolt (1975) that a series of novel anticoagulants, which included brodifacoum, was announced. Today, after a decade of brodifacoum study and experience, the value of this compound in vertebrate pest management, particularly in rodent control, can scarcely be questioned. In order to most effectively build upon this experience, a thorough review of the literature for the period of 1975 to 1985 was undertaken to also include much unpublished information available to the authors. Undoubtedly to a greater extent than any other new vertebrate pesticide, brodifacoum has been …

Keynote Address—Changing Times For Animal Damage Control, James O. Lee Jr.
Vertebrate Pest Conference Proceedings: 12th (1986)
Times do change! USDA's Animal and Plant Health Service, or APHIS, is now in the process of taking over the animal damage control program from the U.S. Fish and Wildlife Service. The transfer will be completed by April 1. This is the opposite of what was happening back in 1939. At that time, a government reorganization plan resulted in the transfer of the Bureau of Biological Survey—-forerunner of Fish and Wildlife Service--from Agriculture to Interior; and with it went the ADC program. We're pleased to have the ADC program back at Agriculture. We never lost interest in it. While the …

Trends Of Predator Losses Of Sheep And Lambs From 1940 Through 1985, Clair E. Terrill
Vertebrate Pest Conference Proceedings: 12th (1986)
Mortality of sheep and lambs from all causes and from predator losses from 1940 through 1985 for the United States is presented including economic aspects. Lamb losses from all causes were 9% of the lamb crop in 1940 and were generally higher thereafter and reached a peak in 1978 of 14%. Losses of sheep 1 year old and older from all causes were 7.5% in 1940 remained somewhat higher through the '60s and then declined to a low of 5.2% in 1985. Calculation of predator losses were based on an upward trend of lamb losses relative to sheep losses with …

An Urban Roof Rat Control Program In Orange County, California, Gilbert L. Challet
An Urban Roof Rat Control Program In Orange County, California, Gilbert L. Challet
Vertebrate Pest Conference Proceedings: 12th (1986)
A program to control roof rats (Rattus rattus) has been conducted by the Orange County Vector Control District since 1975. Orange County is located in southern California just south of Los Angeles and is composed of 782 square miles of coastal foothills and alluvial plain with a population of 2 million. Urbanization takes up about one-half the total area and it is mainly a semi-desert situation with usually less than 15 inches of rain a year. However, because of the balmy temperature and imported water, vegetation grows rampant. Vegetation is used by the rats as harborage (Algerian ivy, …
Population Dynamics And Expansion Rates Of Black-Tailed Prairie Dogs, Lyle A. Crosby, Randy Graham
Population Dynamics And Expansion Rates Of Black-Tailed Prairie Dogs, Lyle A. Crosby, Randy Graham
Vertebrate Pest Conference Proceedings: 12th (1986)
The purpose of this review is to describe population dynamics and annual rates of increase of black-tailed prairie dogs (Cynomys ludovicianus) and to determine annual expansion rates of uncontrolled populations. Their reproductive characteristics, including social behavior are examined as they relate to these factors. In this analysis, the first step is to determine the average number of male and female prairie dogs of breeding age that are present at each burrow system before and after the reproductive cycle. From this determination the total number of prairie dogs is determined, based on the average density of active burrows for …
Biological Status Of Mountain Lions In California, E. Lee Fitzhugh, W. Paul Gorenzel
Biological Status Of Mountain Lions In California, E. Lee Fitzhugh, W. Paul Gorenzel
Vertebrate Pest Conference Proceedings: 12th (1986)
Mountain lions (Felis concolor) symbolize wilderness. The "wild west," a supreme predator, supreme quarry, destroyer of wildlife (game and nongame), livestock, and "trophy" hunting. They are the epitomy of controversy in California. In this paper we will review the history of management and present legal status of mountain lions in California, the political situation leading to the present status, and some of the biological factors that have been controversial, particularly relating to population status and trends.
The Mechanical Control Of Bushpig, Potamochoerus Porcus, In Zimbabwe, Michael La Grange
The Mechanical Control Of Bushpig, Potamochoerus Porcus, In Zimbabwe, Michael La Grange
Vertebrate Pest Conference Proceedings: 12th (1986)
Bushpig, Potamocheorus porcus, occurring naturally in the high rainfall areas of Zimbabwe, have become a major threat to maize producers in the country. Traditional means of control including hunting have been unsuccessful in keeping the numbers to a tolerable level owing to the secretive and cunning nature of the animal. The use of poisons has been discouraged because of indiscriminate use and problems of secondary poisoning, so alternative methods of mechanical control were sought. Several methods evolved during experimentation, producing a strategy to control bushpig throughout the year.
