Five years (2000-2004) of post-reconstruction monitoring of freshwater tidal wetlands in the urban Anacostia River, Washington, D.C. USA Five years (2000-2004) of post-reconstruction monitoring of freshwater tidal wetlands in the urban Anacostia River, Washington, D.C. USA
The Anacostia River in Washington, D.C. USA consisted of over 809 hectares (2000 acres) of freshwater tidal wetlands before mandatory dredging removed most of them in the first half of the 20th century. Much of this13 kilometer (8 mile) reach was transferred to the National Park Service (NPS). Planning processes in the 1980's envisioned a restoration (rejuvenation) of some wetlands for...

Atlantic Seaduck Project Atlantic Seaduck Project
Atlantic Seaduck Project is being conducted to learn more about the breeding and moulting areas of seaducks in northern Canada and more about their feeding ecology on wintering areas, especially Chesapeake Bay. Satellite telemetry is being used to track surf scoters wintering in Chesapeake Bay, Maryland and black scoters on migrational staging areas in New Brunswick, Canada to breeding...

Migration, home range, and important use areas of Florida sub-adult bald eagles Migration, home range, and important use areas of Florida sub-adult bald eagles
Long distance movements of Bald Eagles (Haliaeetus leucocephalus) have prevented a thorough documentation of their migration when monitored with traditional methods of banding and radio telemetry. I used satellite telemetry to determine diurnal and nocturnal important use areas (IUAs), migration routes, stopover sites, and home ranges of 69 migratory and non-migratory Florida sub-adult...

Birds and polycyclic aromatic hydrocarbons Birds and polycyclic aromatic hydrocarbons
Polycyclic aromatic hydrocarbons (PAH) are present throughout the global environment and are produced naturally and by activities of humans. Effects of PAH on birds have been determined by studies employing egg injection, egg immersion, egg shell application, single and multiple oral doses, subcutaneous injection, and chemical analysis of field-collected eggs and tissue. The four-to six...

Assessing and Understanding Trail Degradation: Results from Big South Fork National River and Recreational Area Assessing and Understanding Trail Degradation: Results from Big South Fork National River and Recreational Area
This report describes results from a comprehensive assessment of resource conditions on a large (24%) sample of the trail system within Big South Fork National River and Recreational Area (BSF). Components include research to develop state-of-knowledge trail impact assessment and monitoring methods, application of survey methods to BSF trails, analysis and summary of results, and...

The need for coherence between waterfowl harvest and habitat management The need for coherence between waterfowl harvest and habitat management
Two of the most significant management efforts affecting waterfowl populations in North America are the North American Waterfowl Management Plan (the Plan) and Federal harvest management programs. Both the Plan and harvest management are continental in scope, involve an extensive group of stakeholders, and rely on adaptive processes of biological planning, implementation, and evaluation...

Assessing peridomestic entomological factors as predictors for Lyme disease Assessing peridomestic entomological factors as predictors for Lyme disease
The roles of entomologic risk factors, including density of nymphal blacklegged ticks (Ixodes scapularis), prevalence of nymphal infection with the etiologic agent (Borrelia burgdorferi), and density of infected nymphs, in determining the risk of human Lyme disease were assessed at residences in the endemic community of South Kingstown, RI. Nymphs were sampled between May and July from...

Visitor evaluations of management actions at a highly impacted Appalachian Trail camping area Visitor evaluations of management actions at a highly impacted Appalachian Trail camping area
Protected area management involves balancing environmental and social objectives. This is particularly difficult at high-use/high-impact recreation sites, because resource protection objectives may require substantial site management or visitor regulation. This study examined visitors? reactions to both of these types of actions at Annapolis Rocks, Maryland, a popular Appalachian Trail...
