Effects Of A Bird Hazard Reduction Force On Reducing Bird/Aircraft Strike Hazards At The Atlantic City International Airport, Nj., Andrew J. Montoney, H. Christopher Boggs
Effects Of A Bird Hazard Reduction Force On Reducing Bird/Aircraft Strike Hazards At The Atlantic City International Airport, Nj., Andrew J. Montoney, H. Christopher Boggs
Wildlife Damage Management Conference
Bird-aircraft strikes at the Atlantic City International Airport (ACY) increased from 18 in 1989 to 37 in 1990. The number of bird-aircraft strikes involving gulls (Larus spp.) during this time rose from 6 to 27, a 350% increase. The predominant species involved in bird strikes was the laughing gull (L. atricilla). Pursuant to an interagency agreement between the U.S. Department of Transportation (USDOT), Federal Aviation Administration (FAA) and the U.S. Department of Agriculture (USDA)/ Animal and Plant Health Inspection Service (APHIS)/ Animal Damage Control (ADC), ADC established a Emergency/Experimental Bird Hazard Reduction Force (BHRF) at ACY …

Wildlife Conservation and Management
The status of black bears in North America ranges from pest to threatened. The species appears relatively secure throughout most parts of its range except the southeastern coastal plain; in this region a number of disjunct populations exist on primarily publicly owned lands. Concern over the status of Ursus americanus luteolus led to a petition to list this subspecies under the Endangered Species Act. The Endangered Species Act is arguably the most important wildlife legislation in recent years. However, applying this valuable, but young, untested, and evolving legislation to the black bear subspecies is judged unwarranted and premature because of …
Competitive Interaction Between Crested Wheatgrasses And Cheatgrass, Mark G. Francis
Competitive Interaction Between Crested Wheatgrasses And Cheatgrass, Mark G. Francis
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Current revegetation practices in the lntermountain West include the use of Nordan (Agropyron desertorum) and Hycrest (A. cristatum x desertorum) crested wheatgrass on rangeland susceptible to cheatgrass (Bromus tectorum) invasion, although little quantitative data exists that compares their competitive abilities. We evaluated both the competitive ability of Hycrest and Nordan in two-species mixtures with cheatgrass, and evaluated seedling establishment characteristics for all three species in a greenhouse study. Linear and nonlinear models were developed for a range of densities for each species to predict median above-ground biomass and tiller numbers. In both experiments, increasing …
The Cache Valley Shoshones: Cultural Change, Subsistence, And Resistance, To 1870, John W. Heaton
The Cache Valley Shoshones: Cultural Change, Subsistence, And Resistance, To 1870, John W. Heaton
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
During the eighteenth and nineteenth centuries, the xii Shoshones of Cache Valley evolved from scattered pedestrian hunter-gatherers to large, armed, mounted bands that hunted and gathered from the Great Basin to the Plains. Trade with European Americans helped initiate this evolution. However, Shoshones did not respond passively to the presence of European Americans. Shoshones actively sought change, and incorporated trade goods into their culture within a Shoshone context. They adapted to each wave of European Americans that they encountered. When Mormons dispossessed them of their land, Cache Valley Shoshones resisted by going on the offensive. Finally overwhelmed, the remnants of …
