Wildlife Damage Management On A Public Water Supply, Paul J. Lyons Oct 1993

Wildlife Damage Management On A Public Water Supply, Paul J. Lyons

Wildlife Damage Management Conference

Wildlife populations can pose a variety of problems to managers of public water supplies. Further, new federal and state regulations governing the management and protection of drinking water supplies require greater consideration and mitigation of these problems. The Metropolitan District Commission (MDC) manages watershed lands that provide high quality drinking water to more than 2.4 million people in Massachusetts. This water originates from the central and western portions of the state, from 3 watersheds and 2 reservoirs that also provide habitat for a wide variety of wildlife species. In recent years, the MDC has evaluated the impacts of various wildlife …

The Use Of Odors To Induce Avoidance Behavior In Pine Voles, Christopher J. Salatti, Anthony D. Woolhouse, John G. Vandenbergh Oct 1993

The Use Of Odors To Induce Avoidance Behavior In Pine Voles, Christopher J. Salatti, Anthony D. Woolhouse, John G. Vandenbergh

Wildlife Damage Management Conference

Commercial orchards, ornamental nurseries, and residential horticulture in North Carolina experience economic losses due to pine vole (Microtus pinetorum) depredation. Predator odors and the herbicide Casoron were tested as potential repellents for pine voles. To test for avoidance behavior, animals were allowed to build a nest in one of two chambers attached to each arm of a Y-maze. The cage containing the nest was treated with either a test repellent compound, methylene chloride (solvent control), or left unmanipulated (control). Animals were categorized as either maintaining or changing nest cage preference between pre-test and test periods. The number of …

Status And Management Of Vole Damage To Horticultural Plantings In North Carolina, Peter T. Bromley, William T. Sullivan Jr. Oct 1993

Status And Management Of Vole Damage To Horticultural Plantings In North Carolina, Peter T. Bromley, William T. Sullivan Jr.

Wildlife Damage Management Conference

A trapping study in 1979 indicated that voles (Microtus pennsylvanicus and M. pinetorum) were distributed widely in North Carolina. In 1991, Extension Agents with the North Carolina Cooperative Extension Service were surveyed to determine the distribution, nature and severity of vole damage to horticultural plantings, home orchards, and other plantings. Data from the statewide trapping survey and the poll of agents coincided to indicate that voles, particularly pine voles, caused damage from the mountains to the coast. Existing, legal control methods were judged grossly inadequate by agents. Pursuant to the surveys, the North Carolina Pesticide Board and the …

Strategies To Address Human Conflicts With Raccoons And Black Bears In New Hampshire, Marsha E. Barden, Dennis Slate, Robert T. Calvert, Paul W. Debow Oct 1993

Strategies To Address Human Conflicts With Raccoons And Black Bears In New Hampshire, Marsha E. Barden, Dennis Slate, Robert T. Calvert, Paul W. Debow

Wildlife Damage Management Conference

The Cooperative Animal Damage Control program in New Hampshire has received increasing requests for assistance over the past 5 years. This trend is due largely to changing public concern over black bears (Ursus americanus) in residential areas and an epizootic of the Mid-Atlantic strain of rabies in raccoons (Procyon lotor). A growing number of requests is related to improper garbage storage and feeding of songbirds during late spring and summer. Some traditional methods, especially live- trapping and relocation, are not generally appropriate to resolve these conflicts. In this paper we discuss trends in requests for assistance …

The Applicability And Biopolitics Of Contraceptive Techniques For Deer Management, Robert J. Warren, Lisa M. White Oct 1993

The Applicability And Biopolitics Of Contraceptive Techniques For Deer Management, Robert J. Warren, Lisa M. White

Wildlife Damage Management Conference

While regulated public hunting or controlled lethal reduction programs are effective in controlling whitetailed deer (Odocoileus virginianus) populations in most areas, increasingly there are settings (e.g., urban and suburban environments) where such programs are either unsafe or publicly unacceptable. Past research with contraceptive techniques in deer have shown these techniques to be either ineffective or infeasible for managerial implementation. Current research with immunocontraceptives show promise as being both effective and feasible for field application. Immunocontraceptive vaccines can be delivered remotely and are highly effective in causing infertility in most treated does. Much more research is needed before these …

Advancing Deer Repellent Performance: Fine-Tuning Hinder Applications And Potential Uses For Insecticidal Soaps, Michael J. Fargione, Milo E. Richmond Oct 1993

Advancing Deer Repellent Performance: Fine-Tuning Hinder Applications And Potential Uses For Insecticidal Soaps, Michael J. Fargione, Milo E. Richmond

Wildlife Damage Management Conference

Deer feed on buds, shoots, leaves and fruit (Scott and Townsend 1985), and cause substantial economic losses for many apple producers (Purdy et al. 1987). A variety of mitigation techniques are used to control such damage including deer population reduction via hunting, exclusion fencing and scare devices. However, most commercial apple producers rely on home-made or commercial repellents to control deer damage (Purdy et al. 1987). Despite their popularity, repellents have often provided only limited or highly-variable control (Conover 1984, 1987, Hygnstrom and Craven 1988). There is considerable need to improve the performance of existing repellents, or to identify new …

Global News After The Cold War, Ted Pease

Journalism and Communication Faculty Publications

WITH THE BREAKUP of the Soviet Union in 1991, the Cold War ended. The media not only watched, but played a crucial role in the years after 1985, when Mikhail Gorbachev came to power, as rapid developments dramatically changed the world as we had known it. Images of seminal change agents in what had been the Eastern bloc-Gorbachav, Lech Walesa, Vadav Havel-facing leaders from the West-Ronald Reagan, Margaret Thatcher, Helmut Kohl and Pope John Paul II-mingled with those of explosions at Chernobyl and Tiananmen Square, the of the Berlin Wall and the Bucharest crowds who brought down a Romanian tyrant. …

Elastic Scaling Of Small Structures, Kim Aaron Sep 1993

Elastic Scaling Of Small Structures, Kim Aaron

Small Satellite Conference

As aerospace designers strive to build smaller systems, it is important that they understand scaling laws to take full advantage of the inherent strength of small structures. Simple geometric scaling yields masses that scale in proportion to ℓ3. However, in the process, the stress levels decrease, and the materials are not used to full advantage. Also, the resistance to buckling increases as the length decreases. With "elastic scaling," as the dimension parallel to the predominant load shortens, the dimension normal to the main load is thinned down even faster. This preserves a constant factor of safety with respect to the …

Sea-Launch For Small Satellites: An American/Russian Joint Venture, John Draim Sep 1993

Sea-Launch For Small Satellites: An American/Russian Joint Venture, John Draim

Small Satellite Conference

This paper describes practical means of bypassing the two major impediments to the commercial exploitation of space. These two impediments or constraints, are the affordability, reliability, and availability of launch vehicles on the one hand, and the affordability, availability, and flexibility of launch facilities on the other hand. As to the former, US launch vehicles are noted for their technological complexity, their high cost, and their susceptibility to single point failures. As to the latter, our land launch facilities are costly, inadequate and congested. Schedule delays on one launch cause delays for all succeeding launches from a given launch pad. …
