Managing Birds And Controlling Aircraft In The Kennedy Airport–Jamaica Bay Wildlife Refuge Complex: The Need For Hard Data And Soft Opinions, Kevin Brown, R. Michael Erwin, Milo E. Richmond, P A. Buckley, John Tanacredi Ph.D., Dave Avrin

Faculty Works: CERCOM

During the 1980s, the exponential growth of laughing gull (Larus atricilla) colonies, from 15 to about 7600 nests in 1990, in the Jamaica Bay Wildlife Refuge and a correlated increase in the bird-strike rate at nearby John F. Kennedy International Airport (New York City) led to a controversy between wildlife and airport managers over the elimination of the colonies. In this paper, we review data to evaluate if: (1) the colonies have increased the level of risk to the flying public; (2) on-colony population control would reduce the presence of gulls, and subsequently bird strikes, at the airport; …

Hillsborough Independent Monitoring Program Technical Memorandum Lower Hillsborough River Benthic Monitoring 2000, Stephen A. Grabe, David J. Karlen, Christina M. Holden, Barbara Goetting

Reports

The Lower Hillsborough River system has been heavily impacted by stormwater discharges and reduction of freshwater inflow (Mote Marine Laboratory 1984; Water & Air Research Inc. 1993; Water & Air Research & SOl Environmental Services, Inc. 1994) .. A consequence has been increased salinity, the accumulation of fine-grained sediments and associated contaminants, as well as lowered DO levels. Analysis of past EPCHC data for the Lower Hillsborough River showed that benthic community characteristics (as measured by the TBBI) were not necessarily related to dissolved oxygen, salinity, or depth (Grabe and Karlen 1999; Grabe el al. 2000). The data collected through …

Visitor Capacity In The National Park System, Dr. Glenn E. Haas, National Park Service, U.S. Department Of The Interior

All U.S. Government Documents (Utah Regional Depository)

This paper reviews social science research on visitor capacity relevant to units of the National Park System (NPS). Visitor capacity is defined as a prescribed number and type of people that an area will accommodate given the desired natural/cultural resource conditions, visitor experiences, and management program. Some 40 years of scientific investigation illustrate the complexity of the interaction between human use and park resources. This paper provides insights from environmental psychology on person-environment relationships, nine capacity-related research findings, a matrix of NPS studies, and recommendations for a program of research.

Weed Control Methods Handbook: Tools & Techniques For Use In Natural Areas, Mandy Tu, Callie Hurd, John M. Randall, The Nature Conservancy

All U.S. Government Documents (Utah Regional Depository)

Invasive non-native plants are a serious threat to native species, communities, and ecosystems in many areas around the world. They can compete with and displace native plants, animals, and other organisms that depend on them, alter ecosystem functions and cycles significantly, hybridize with native species, and promote other invaders. The good news is that many plant invasions can be reversed, halted or slowed, and in certain situations, even badly infested areas can be restored to healthy systems dominated by native species. In most instances this requires taking action to control and manage those invasive plants. This handbook provides you with …

Gottgens, James E. Perry, Et Al

VIMS Articles

Because it is one of the most inaccessible places on earth, this large, rich ecosystem has remained relatively untouched. There is, however, increasing evidence that this area is threatened by a number of activities, including mining, illegal hunting and fishing, indiscriminate use of fire, agricultural development, and deforestation. Careless use of mercury in gold mining, particularly in the northern Pantanal, may have resulted in acute and chronic ecosystem disruption (Hylander et al. 1994, Nogueira et al. 1997, Leady and Gottgens 2001). Wildlife poaching and live animal trade are widespread although hard to quantify. During six months in 1985, the skins …

Land Use Patterns In Relation To Lake Water Quality In The Lake George And Oaks Pond Watersheds, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: Other Area Studies

There has always been an inexplicable wonder associated with the beauty of Maine lakes. In addition to their aesthetic value, lakes and ponds provide important habitats for aquatic and terrestrial wildlife. The attraction of the lake's natural beauty, however, can increase recreational pressures that may lead to human induced eutrophication. Lake George and Oaks Pond were chosen as the Colby Environmental Assessment Team's (CEAT) study sites due to the concern about potential human induced eutrophication of both water bodies. Lake George and Oaks Pond are situated in southern Somerset County, Maine, and experience heavy recreational and developmental uses. Neither water …

Yellow Jackets (Vespula Spp.) Disperse Trillium (Spp.) Seeds In Eastern North America, Jennifer A. Zettler, Timonthy P. Spira, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Approximately 70 plant families worldwide have ant-dispersed seeds (myrmecochory). In this putative ant-plant mutualism, ants are attracted to and disperse seeds that have a lipid-rich elaiosome. We observed yellow jackets (Vespula spp.) dispersing seeds of three elaiosome-bearing species-Trillium cuneatum, T. undulatum and T catesbaei-in the Blue Ridge Mountains of North Carolina and South Carolina. Moreover, we estimated the mean distance yellow jackets dispersed seeds of T. cuneatum by placing intact fruits on index cards and recovering dispersed seeds on sheets placed on the ground surface. Of the seeds presented, 41% were recovered and the average dispersal distance …
