Rodent Damage In Hawaiian Macadamia Orchards, Mark E. Tobin Mar 1992

Rodent Damage In Hawaiian Macadamia Orchards, Mark E. Tobin

Vertebrate Pest Conference Proceedings: 15th (1992)

Roof rats (Rattus rattus) damage an estimated 5-10% of the annual macadamia nut crop in Hawaii, resulting in farm value losses of between $2-4 million. The Denver Wildlife Research Center field station in Hilo, Hawaii studies the biology, impact, and control of rodent pests in Hawaiian agricultural crops. This paper describes field and laboratory research currently being conducted to address rat problems in macadamia nut orchards.


Evaluation Of Methyl Anthranilate As A Bird Repellent In Fruit Crops, Michael L. Avery Mar 1992

Evaluation Of Methyl Anthranilate As A Bird Repellent In Fruit Crops, Michael L. Avery

Vertebrate Pest Conference Proceedings: 15th (1992)

Methyl anthranilate (MA) is a grape-flavored food additive that is aversive to birds. Previous studies had indicated that anthranilates can deter frugivorous birds but that anthranilates are phytotoxic. In this study, I tested the bird repellency to 2 MA formulations on blueberry plants in a large flight pen. Neither MA formulation protected the blueberries from damage by cedar waxwings (Bombycilla cedrorum) or European starlings (Sturnus vulgaris). The encapsulated formulation, however, was nonphytotoxic. Due to the on-going need for safe bird deterrent compounds, further development and testing of MA as a bird repellent on fruit is warranted. …


Marine Spill Response Corporation (Msrc): How It Hopes To Fill The Oil Recovery Requirements Of The Oil Pollution Act Of 1990, Gerald P. O'Reilly Jan 1992

Marine Spill Response Corporation (Msrc): How It Hopes To Fill The Oil Recovery Requirements Of The Oil Pollution Act Of 1990, Gerald P. O'Reilly

Marine Affairs Theses and Major Papers

The establishment of Marine Spill Response Corporation (MSRC) is a direct outcome of OPA-90 which will have a substantial effect on domestic shipment, storage and traffic of oil. The ramifications of the law will be felt internationally and it has set a precedent for prevention of oil spills from tankers throughout the world. It will have a positive impact on the environment of the world. But it will be costly and the public will ultimately bear the burden of the environment impact.


Rhode Island Marine Debris Pilot Project, Christina L. Beal Jan 1992

Rhode Island Marine Debris Pilot Project, Christina L. Beal

Marine Affairs Theses and Major Papers

The Rhode Island Marine Debris Pilot Project was initiated in Newport, R.I. during the summer of 1991. The objective of the project was to decrease recreational boaters' contribution to marine debris. Two methods were used to achieve this goal. First, trash and recycling disposal facilities were increased around the harbor. Secondly, educational literature on the environmental consequences of marine debris, and the law that applies to overboard disposal, were distributed throughout the local marine community. The implementation of the pilot project led to a significant increase in the amount of debris brought ashore by boaters, and a decrease in the …


Ontario's Blue Box As An Agent Of Change, Robert Nathaniel Burgess Jan 1992

Ontario's Blue Box As An Agent Of Change, Robert Nathaniel Burgess

Theses and Dissertations (Comprehensive)

Ontario's blue box has elicited strong arguments from observers on both sides of a debate regarding the recycling programme‘s promotion of social change in the province. Both supporters and critics agree on our eventual need to change from a consumer to a conserver society through the 3Rs of waste management (reduce. reuse. recycle). but they disagree on whether the blue box programme ultimately encourages this change. Disagreement also exists regarding the means to achieving change. With supporters of the blue box approach favouring working within the system whereas critics tend to favour a more radical approach. Practical criticisms concern the …
