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
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 …
Deer Damage Incurred By Homeowners During 1995 In Virginia, Ben C. West, James A. Parkhurst
Deer Damage Incurred By Homeowners During 1995 In Virginia, Ben C. West, James A. Parkhurst
Wildlife Damage Management Conference
Damage caused by white-tailed deer (Odocoileus virginianus) is a problem for some homeowners in Virginia. As part of a broader effort to evaluate the attitudes and perceptions of agricultural producers and homeowners toward deer damage in Virginia, a mail questionnaire was developed and implemented during the fall of 1996. The survey yielded 732 useable responses and, of those, 261 individuals indicated they were homeowners and grew at least one planting during 1995. Many homeowners (36%) indicated that deer caused damage to at least one of their plantings during 1995. Of those who had experienced damage, most (61%, n=57) …

Wildlife Damage To Agricultural Crops In Pennsylvania: The Farmers' Perspective, Margaret C. Brittingham, Walter M. Tzilkowski, James M. Zeidler, Matthew J. Lovallo
Wildlife Damage Management Conference
Agricultural damage by wildlife is a major concern for both agricultural and wildlife agencies at the state and federal level. Our objective was to estimate wildlife damage to agricultural crops on a statewide basis. We sent questionnaires to 4,958 farmers and 1,003 were returned after 2 mailings. Twenty-five percent of farmers responding to our survey rated the level of wildlife damage to their crops as severe or very severe, 46% as moderate, and 29% had none or very little. Mean levels of crop loss to wildlife ranged from 6% for wheat to 10% for corn grain, and white-tailed deer ( …

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
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 …

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.

Characteristics Of Gray Squirrel Release Sites Selected By Kentucky Nuisance Wildlife Control Operators, Sara Steen-Ash, Thomas G. Barnes, Jeff T. Hutchinson, Jeffery L. Larkin, Brian E. Washburn, Jason L. Weese, Henry F. Yacek Jr.
Wildlife Damage Management Conference
A telephone survey of Kentucky nuisance wildlife control operators (NWCOs) (n=66) was conducted in April of 1997 to assess their knowledge and practices regarding nuisance gray squirrel (Sciurus carolinensis) release-site habitat. Thirty-three percent of NWCOs (n=22) trapped and relocated >1 nuisance gray squirrel in the previous year and these individuals/companies were selected for the survey. NWCOs trap and release >1,700 squirrels annually in Kentucky. Sampled release sites varied in size from 18 to 5,200 acres, and >70% were classified as poor to marginal habitat. Three of the release sites sampled provided adequate to optimum gray squirrel habitat. Actual …
Conservation Of A Dinosaur In Modern Times: South Carolina’S Alligator Management Program, Walter E. Rhodes
Conservation Of A Dinosaur In Modern Times: South Carolina’S Alligator Management Program, Walter E. Rhodes
Wildlife Damage Management Conference
American alligator (Alligator mississippiensis) conservation is necessary given the animal's role in wetland ecosystems and its economic value. Although the alligator appears to be no longer threatened with extinction, the reptile’s perceived reputation and a burgeoning human population combine to create a management paradox. Alligator management in South Carolina consists of a Nuisance Control Program, a Private Lands Harvest Program, and public education. Annually, over 750 alligator complaints are received by the South Carolina Department of Natural Resources (SCDNR), and harvest averages about 250 animals. To address alligator/human interaction in rural habitats, a harvest on private lands was …
The Mass Media And Stakeholders' Beliefs About Suburban Wildlife, Cynthia A. Loker, James Shanahan, Daniel J. Decker
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.
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.

Liquid-Liquid Immiscibility In Lipid Monolayers, John P. Hagen, Harden M. Mcconnell
Chemistry and Biochemistry
Some binary lipid mixtures form coexisting liquid phases when spread at the air/water interface. This work describes the pressure–composition phase diagrams of binary mixtures of four unsaturated phosphatidylcholines with dihydrocholesterol. These four binary mixtures have critical compositions of approximately fifty mole percent, and average critical exponents of 0.25±0.07. The data can also be approximated by a regular solution thermodynamic model, yielding parameters for the non-ideality of these mixtures.

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 …
Assembly And Disassembly Of Dna Polymerase Holoenzyme, Daniel J. Sexton, Anthony J. Berdis, Stephen J. Benkovic
Assembly And Disassembly Of Dna Polymerase Holoenzyme, Daniel J. Sexton, Anthony J. Berdis, Stephen J. Benkovic
Chemistry Faculty Publications
The complex task of genomic replication requires a large collection of proteins properly assembled within the close confines of the replication fork. The mechanism and dynamics of holoenzyme assembly and disassembly have been investigated using steady state and pre-steady state methods as opposed to structural studies, primarily due to the intrinsic transient nature of these protein complexes during DNA replication. The key step in bacteriophage T4 holoenzyme assembly involves ATP hydrolysis, whereas disassembly is mediated by subunit dissociation of the clamp protein in an ATP-independent manner.

The Legal Roles And Responsibilities Of A Community Concerning Crop Depredation By White-Tailed Deer, Eric G. Darracq, Stephen R. Chapman
Eastern Wildlife Damage Management Conference: 8th (1997)
The interwoven issues of the legal roles and responsibilities that landowners (i.e., farmers, foresters, and hunters) and a state agency have to control deer densities in rural areas that directly affect crop depredation and various stakeholders will be addressed in this paper. Because unmanaged deer populations severely can damage agricultural crops, the financial cost of this deer damage is borne entirely by individual private landowners. The South Carolina Department of Natural Resources (SCDNR) is the regulatory state agency in South Carolina responsible for annually promulgating rules and regulations pertaining to white-tailed deer harvest by hunters. Even though deer are property …

The Use Of Gis To Delineate Potential Urban Deer Habitat, David M. Kocka, Frederick M. Garst
Eastern Wildlife Damage Management Conference: 8th (1997)
Overabundant deer herds in urban environments often require new and creative approaches to properly evaluate the situation and gain support for population management. To determine potential white-tailed deer (Odocoileus virginianus) habitat for the Harrisonburg, Virginia, Deer Task Force, a geographic information systems (GIS) map was created that reflected current land use in the city. Data were compiled using 2m resolution Digital Ortho Quarter Quads. Using this backdrop, land use zones were digitized on-screen. Wooded (13%), Agricultural (20%), and Open Areas (14%) land use types accounted for nearly half the city's land area and represent a conservative estimate of …

Electric Fencing Reduces Heron Predation At Northeastern Trout Hatcheries, Mark E. Tobin, James F. Glahn, Erica S. Rasmussen
Eastern Wildlife Damage Management Conference: 8th (1997)
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 …
