Distribution patterns of wintering sea ducks in relation to the North Atlantic Oscillation and local environmental characteristics Distribution patterns of wintering sea ducks in relation to the North Atlantic Oscillation and local environmental characteristics
Twelve species of North American sea ducks (Tribe Mergini) winter off the eastern coast of the United States and Canada. Yet, despite their seasonal proximity to urbanized areas in this region, there is limited information on patterns of wintering sea duck habitat use. It is difficult to gather information on sea ducks because of the relative inaccessibility of their offshore locations...

Optimal control of native predators Optimal control of native predators
We apply decision theory in a structured decision-making framework to evaluate how control of raccoons (Procyon lotor), a native predator, can promote the conservation of a declining population of American Oystercatchers (Haematopus palliatus) on the Outer Banks of North Carolina. Our management objective was to maintain Oystercatcher productivity above a level deemed necessary for...

An inventory of terrestrial mammals at national parks in the Northeast Temperate Network and Sagamore Hill National Historic Site An inventory of terrestrial mammals at national parks in the Northeast Temperate Network and Sagamore Hill National Historic Site
An inventory of mammals was conducted during 2004 at nine national park sites in the Northeast Temperate Network (NETN): Acadia National Park (NP), Marsh-Billings-Rockefeller National Historical Park (NHP), Minute Man NHP, Morristown NHP, Roosevelt-Vanderbilt National Historic Site (NHS), Saint-Gaudens NHS, Saugus Iron Works NHS, Saratoga NHP, and Weir Farm NHS. Sagamore Hill NHS, part...

Multi-scale occupancy estimation and modelling using multiple detection methods Multi-scale occupancy estimation and modelling using multiple detection methods
Occupancy estimation and modelling based on detection–nondetection data provide an effective way of exploring change in a species’ distribution across time and space in cases where the species is not always detected with certainty. Today, many monitoring programmes target multiple species, or life stages within a species, requiring the use of multiple detection methods. When multiple...

Design and implementation of estimation-based monitoring programs for flora and fauna: A case study on the Cherokee National Forest Design and implementation of estimation-based monitoring programs for flora and fauna: A case study on the Cherokee National Forest
Science-based monitoring of biological resources is important for a greater understanding of ecological systems and for assessment of the target population using theoretic-based management approaches. When selecting variables to monitor, managers first need to carefully consider their objectives, the geographic and temporal scale at which they will operate, and the effort needed to...

Deer exposed to exceptionally high concentrations of lead near the Continental Mine in Idaho, USA Deer exposed to exceptionally high concentrations of lead near the Continental Mine in Idaho, USA
Habitat surrounding the inactive Continental Mine in northern Idaho, USA, supports bear (Ursus arctos, Ursus americanus), moose (Alces alces), elk (Cervus elaphus), woodland caribou (Rangifer tarandus caribou), and abundant mule (Odocoileus hemionus) and white-tailed deer (Odocoileus virginianus). Tailings on the mining site were capped and remediated in 2003 to reduce environmental...
