State Of The Fisheries Report 1996/1997, Jim W. Penn

Status Reports of the Fisheries and Aquatic Resources

The State of the Fisheries document is designed as an essential supplement to the Annual Report to Parliament. By summarising data such as landings, ettort, catch rates, stock assessment and breeding stock levels, this document provides a valuable reference point for all Western Australian fisheries of major importance to the commercial, recreational and aquaculture sectors. Information relevant to the Department of Fisheries' Fish and Fish Habitat Protection Program is also provided. The report indicates that overall the major fish stocks which support fisheries in Western Australia continue to be in a reasonably healthy condition. Those species which are being harvested …

Coordinate Regulation Of G- And C Strand Length During New Telomere Synthesis, Xinqing Fan, Carolyn Mary Price

Department of Chemistry: Faculty Publications

We have used the ciliate Euplotes to study the role of DNA polymerase in telomeric C strand synthesis. Euplotes provides a unique opportunity to study C strand synthesis without the complication of simultaneous DNA replication because millions of new telomeres are made at a stage in the life cycle when no general DNA replication takes place. Previously we showed that the C-strands of newly synthesized telomeres have a precisely controlled length while the G-strands are more heterogeneous. This finding suggested that, although synthesis of the G-strand (by telomerase) is the first step in telomere addition, a major regulatory step occurs …

Interactive And Batch Creation Of Oodb Medical Vocabularies, Muhammad Arif

Theses

Controlled vocabularies are becoming popular for knowledge representation and querying. They are particularly helpful in the medical field since they can unify disparate terminologies and provide information in a compact, comprehensible manner. In this thesis, we present a mechanism to create OODB controlled medical vocabularies from flat-file format. We also describe a tool by which a user can interactively create, edit and browse the vocabulary. For better understanding of the structure of the vocabulary we designed our interface as a graphical editor and browser. The user of this interface will typically be a medical expert who either wants to add …

Development Of An Integrated Canada Goose Management Program In Virginia, Martin Lowney, Phil Eggborn, Gary Costanzo, Don Patterson

Wildlife Damage Management Conference

Wildlife managers in the State of Virginia developed an integrated Canada goose (Branta canadensis) damage management program in 1996 to address increasing damage caused by resident (non-migratory) Canada geese, primarily in urban/suburban areas. The previous Canada goose damage management program relied primarily on harassment and relocation. The integrated program was made available to citizens, homeowner associations, businesses, organizations, city and county governments, and state and federal agencies in 1997. The Integrated Canada Goose Management Program was developed by U.S. Department of Agriculture-Animal and Plant Health Inspection Service-Wildlife Services, Virginia Department of Agriculture and Consumer Services, Virginia Department of …

Historical Forces Shaping Americans' Perceptions Of Wildlife And Human-Wildlife Conflicts, Michael R. Conover, Denise O. Conover

Wildlife Damage Management Conference

From colonial times until the 19th century, the dominant American view of wildlife and its management was dualistic—wildlife species were divided into good animals (those which had commercial value or could be eaten) or bad animals (those which threatened the colonists’ safety or food supply). Philosophically, early colonial Americans believed that the environment was to be manipulated for man’s purposes. Under the impact of modernization, Darwinian influence, over-exploitation of resources, and environmentally-conscious professionals, Americans in the late 19th century began to appreciate the recreational value of wildlife and to develop a more protective attitude toward it. Still the dichotomy between …

Private Nuisance Wildlife Control: Is There A Future In Kansas?, Charles Lee, Philip Gipson, Lucas Koch

Wildlife Damage Management Conference

The private industry involvement in nuisance animal damage control is increasing in Kansas. Improved oversight of that industry is needed and the Kansas Department of Wildlife and Parks (KDWP) plans to implement a mandatory education and certification program beginning in 1998. KDWP currently issues permits to individuals who wish to trap or control nuisance animals outside of normal harvest seasons. Individuals who have held these permits to conduct nuisance animal damage control were surveyed in 1995 to better understand the status and needs of that industry in Kansas. A 3-page mail survey was sent to all 93 permit holders. Raccoons …

Wildlife-Caused Losses For Catfish Producers In 1996, Alice P. Wywialowski

Wildlife Damage Management Conference

In January 1997, the National Agricultural Statistics Service (NASS) surveyed catfish producers about wildlife-caused losses in 1996, Of the 1,465 catfish producers in 15 states surveyed, 1,008 (68.8%) agreed to complete the survey. Surveys were conducted primarily by telephone, but some producers received mail surveys. The response rated varied among states. The majority of catfish producers were in Mississippi (n=-300), followed by Alabama (n=163), and then Arkansas (n=117). The remaining states each had < 100 respondents. Data were analyzed for 6 regions, each with a sample size of > 100 respondents. Overall, 69% of catfish producers cited a wildlife-caused loss of catfish. Producers cited losses to wildlife most frequently in Mississippi (81%), followed by states adjoining …

Electric Fencing Reduces Heron Predation At Northeastern Trout Hatcheries, Mark E. Tobin, James F. Glahn, Erica S. Rasmussen

Wildlife Damage Management Conference

Great blue herons (Ardea herodius) are the most common avian predator at commercial trout hatcheries in the northeastern United States. We evaluated a 2-strand electric fence for excluding this species from raceways at 2 commercial trout hatcheries in central Pennsylvania. Fences consisted of high density polyethylene 400-lb strength tape supported by fiberglass posts and energized by either a battery-powered or a solar-powered fence charger. Labor and material for constructing the fences at the 2 sites averaged $1.32/m of raceway. Bird visitation at the 2 sites initially declined, but returned to pre-installation levels. However, bird use of raceways declined …

Attempted Relocation Of A Ring-Billed Gull Roost At Washington National Airport, Jessica Dewey, Martin Lowney

Wildlife Damage Management Conference

Gulls, particularly ring-billed gulls [Larus delawarensis], have been identified as a threat to aircraft operations at Washington National Airport (now Ronald Reagan National Airport) in northern Virginia. Through bird surveys conducted in 1992, 1993, and 1997, an estimated 7,000 gulls were observed roosting during winter on the Potomac River near the airport. A harassment program was run on 5 consecutive evenings, 24-28 February 1997, to relocate the roosting gulls. Six to 8 people shot pyrotechnics from shore and 2 boats for 2 hours prior to dusk each evening. Each evening the gulls arrived consistently later than the prior …

Double-Crested Cormorant And Ring-Billed Gull Damage Management On Lake Champlain: Are Basin-Wide Objectives Achievable?, Richard Chipman, Dennis Slate, Larry Garland, David Capen

Wildlife Damage Management Conference

Ring-billed gulls (Larus delewarensis) and double-crested cormorants (Phalacrocorx auritus) have nested on Lake Champlain since 1949 and 1982, respectively. Recent increases in cormorant nesting populations and pioneering activities of both species to previously uncolonized islands have resulted in impacts related to accumulation of bird guano and interspecific competition with less common species. Of primary concern are: decreases in wildlife and plant diversity on islands; reduced aesthetics and property values of island associated with the loss of trees; and predation or competition for nesting space with other species such as the state-endangered common tern (Sterna hirundo …

Nesting Populations Of Double-Crested Cormorants, Great Blue Herons, And Great Egrets In The United States And Canada: Implications For Management, Jerrold L. Belant, Laura A. Tyson

Wildlife Damage Management Conference

Populations of piscivorous birds in North America are receiving increasing attention in the southeast United States because of depredations at aquaculture facilities. We obtained recent (most since 1994) estimates for the number of nesting double-crested cormorants (Phalacrocorax auritus), great blue herons (Ardea herodias), and great egrets (Casmerodius albus) in the United States (US) and Canada from published references and by conducting telephone interviews with state and provincial biologists. Using previously-published data, we also determined annual rates of change in the number of cormorants since about 1990. Estimates for minimum numbers of nesting pairs (minimum …

Repellency Of Methyl Anthranilate To Captive Great Egrets, Michael L. Avery, John S. Humphrey, David G. Decker

Wildlife Damage Management Conference

Because effective deterrents are hard to find, it has been suggested that methyl anthranilate (MA) be applied to the surface of fish ponds to discourage bird predation. We conducted two short-term evaluations of a formulation for this use, ReJeX-iT TP-40. First, we assessed the response of tropical fish to TP-40 applications in small wading pools. After 15 minutes, all fish virtually were motionless at or near the bottom of the pool. Fish in the control pools actively swam and most were within 3 cm of the surface of the pool. No mortality occurred, and fish activity returned to almost normal …

Controlling Great-Tailed Grackle Damage To Citrus In The Lower Rio Grande Valley, Texas, James F. Glahn, Jose D. Palacious, Melvin V. Garrison

Wildlife Damage Management Conference

Great-tailed grackle (Quiscalus mexicanus) damage to citrus is a serious concern to producers in the lower Rio Grande Valley of Texas. Damage caused by grackles pecking fruit is initiated by breeding colonies in the spring on immature fruit and extends through the fall and winter on ripening fruit. The most significant damage occurs during the post-breeding period of July through September when neither the currently registered DRC-1339-treated dog food bait nor frightening strategies are effective. Observations by Texas Wildlife Services personnel suggested that watermelon was highly attractive to grackles during the period when dog food baits are poorly …

Development Of The Virginia Cooperative Coyote Control Program To Protect Livestock, Martin Lowney, John Houben, Phil Eggborn

Wildlife Damage Management Conference

The Virginia Cooperative Coyote Control Program was created in 1990 to address increasing livestock losses to coyotes and the inability of producers to solve such problems themselves. The eastern coyote arrived in Virginia in the late 1970s or early 1980s. Lobbying efforts of agricultural groups, such as the Virginia Sheep Federation, helped create a cost-share program administered by the Virginia Department of Agriculture and Consumer Services (VDACS) and U.S. Department of Agriculture-Animal and Plant Health Inspection Service-Wildlife Services (USDA-APHIS-WS). The objective of the program was to educate producers about control methods and to alleviate damage by removing offending coyotes where …

Do You Have Your Skates On?, Gary J. San Julian

Wildlife Damage Management Conference

It is an honor to keynote this conference as we think about our profession in the next century. Jim asked me to predict what the future of wildlife damage management might look like in the year 2020. I explained to him that I have not been actively engaged in doing wildlife damage work for almost 9 years and I had been in an administrative role. Jim knew that I am going back to a faculty position in the next several months. He thought it was great for a person coming out of retirement to predict the future.

The Press And Citizen Participation: A Content Analysis, Lisa Pelstring, James Shanahan, Ben Perry

Wildlife Damage Management Conference

We conducted a content analysis of regional New York State newspapers to assess media coverage of the Department of Environmental Conservation’s (DEC) deer management program. The goal of this analysis was to ascertain media depiction of DEC’s deer management program during the 1985-97 time period. Specifically, this research examines how deer management issues were portrayed both prior to and after implementation of a DEC public participation program (the Citizen Task Force [CTF] process) to determine if deer management issues received more favorable coverage after CTFs were implemented.

Bird Abundance At Accomack County Southern Landfill, Melfa, Virginia, In Relation To Various Management Activities, Laura Francoeur, Martin Lowney

Wildlife Damage Management Conference

Birds, especially gulls (Larus spp.), are attracted to landfills, and when landfills are close to airports, birds can pose a threat to aircraft safety. We conducted a 1-year ecological study to address concerns of the Federal Aviation Administration (FAA) and Accomack County, Virginia, officials over potential wildlife hazards caused by the Accomack County Southern Landfill. During 48 surveys conducted from December 1995 to December 1996, we observed 112,693 birds at the landfill (x̄=503). Nine species represented 97% of all observations. Bird numbers varied during the year, increasing during winter and declining during summer. Bird abundance appeared unaffected by …

The Mass Media And Stakeholders' Beliefs About Suburban Wildlife, Cynthia A. Loker, James Shanahan, Daniel J. Decker

Wildlife Damage Management Conference

This study examines how suburban audiences obtain information about 3 species in New York State (whitetail deer [Odocoileus virginianus], beaver [Castor canadensis], and Canada goose [Branta canadensis]). Respondents in 3 suburban areas were surveyed on concerns and interests about a particular species in their area. Respondents also were surveyed about preferred sources for species information and actual source use. Finally, respondents were surveyed about general media use. “Uses-and-gratifications” theory was used to characterize respondents’ information behavior for species information. Specific recommendations for communication planning are offered.

Vertebrate Damage Management: The Future Of An Evolving Profession, Robert H. Giles Jr.

Wildlife Damage Management Conference

The author argues that an objective of a new group of people taking a systems approach to large wild animal problems should be to manage damage as a cost-reducing role within a total, profitable, long-term system, not necessarily to control the "pest." The needs are for well-grounded financial analyses both for customers, the public, the resources, and the well-being of the profession. A point of view is advanced for the need for evolving pest-related operations into a new, unique profession that is involved in a profound way as an element of a cost-effective total land and human resource production system.

Automated Classification Of Stellar Spectra. Ii: Two-Dimensional Classification With Neural Networks And Principal Components Analysis, Ted Von Hippel, Coryn A.L. Bailer-Jones, Mike Irwin

Publications

We investigate the application of neural networks to the automation of MK spec- tral classification. The data set for this project consists of a set of over 5000 optical (3800–5200°A) spectra obtained from objective prism plates from the Michigan Spec- tral Survey. These spectra, along with their two-dimensional MK classifications listed in the Michigan Henry Draper Catalogue, were used to develop supervised neural network classifiers. We show that neural networks can give accurate spectral type classifications (68 = 0.82 subtypes, rms= 1.09 subtypes) across the full range of spectral types present in the data set (B2–M7). We show also that …

Cytochrome P450 And Organochlorine Contaminants In Black-Crowned Night-Herons From The Chesapeake Bay Region, Usa, Barnett A. Rattner, Mark J. Melancon, Clifford P. Rice, Walter Riley Jr., John D. Eisemann, Randy K. Hines

United States Department of Agriculture Wildlife Services: Staff Publications

Black-crowned night-heron (Nycticorax nycticorax) offspring were collected from a relatively uncontaminated coastal reference site (next to Chincoteague National Wildlife Refuge, VA, USA) and two sites in the Chesapeake Bay watershed (Baltimore Harbor, MD and Rock Creek Park, Washington, DC, USA). Hepatic microsomal activities of benzyloxyresorufin-O-dealkylase and ethoxyresorufin-O-dealkylase were significantly elevated (up to sixfold and ninefold induction, respectively) in pipping embryos from the Baltimore Harbor colony compared to the reference site, whereas values in embryos from the Rock Creek Park colony were intermediate. Concentrations of organochlorine pesticides and metabolites in pipping embryos from both sites …

Multiple Outcomes In Health Services Research: Hypothesis Tests And Power, Donald C. Martin, Paula Diehr, Thomas D. Koepsell, Stephan D. Fihn

UW Biostatistics Working Paper Series

Health services research often is directed towards making small improvements in a number of outcomes that reflect many aspects of the patient’s life rather than a large improvement in a single well defined outcome. A researcher might choose five scales to measure different aspects of treatment outcomes and not expect any large treatment differences on any single outcome measure. O’Brien (1984) has proposed a nonparametric statistical procedure which is particularly well suited to this type of problem and that can result in considerable increases in statistical power. This paper will briefly review O’Brien’s pooled rank method and develop power calculations. …
