Human–Wildlife Interactions
Wild pigs (Sus scrofa) are abundant and widely distributed in the United States. They damage crops and pastures, predate livestock and sensitive species, impact ecosystem functions, and damage personal property. To address these issues, some states in the United States are seeking complete elimination. A frequently asked question by stakeholders is: “What portion of the population needs to be removed annually to reach elimination?” The number 70% is widely touted as the answer. There is little scientific evidence to support that this percent annual removal would be needed to achieve elimination, yet 70% has now become a standard …

Human–Wildlife Interactions
Some avian species have developed the capacity to leverage resource subsidies associated with human manipulated landscapes to increase population densities in habitats with naturally low carrying capacities. Elevated corvid densities and new territory establishment have led to an unsustainable increase in depredation pressure on sympatric native wildlife prey populations as well as in crop damage. Yet, subsidized predator removal programs aimed at reducing densities are likely most effective longer-term when conducted in tandem with subsidy control, habitat management, and robust assessment monitoring programs. We developed decision support software that leverages stage structured Lefkovitch population matrices to compare and identify treatment …
Seal And Polar Bear Behavioral Response To An Icebreaker Vessel In Northwest Greenland, Kate Lomac-Macnair, José Pedro Andrade, Eduardo Esteves
Seal And Polar Bear Behavioral Response To An Icebreaker Vessel In Northwest Greenland, Kate Lomac-Macnair, José Pedro Andrade, Eduardo Esteves
Human–Wildlife Interactions
Icebreaker vessels are important scientific tools, enabling access and research within the polar regions of the world, including the High Arctic. These vessels have the potential to overlap with marine mammal habitats in infrequently studied areas. Marine mammal behavioral responses to icebreaker vessel presence and distance at which responses occur are not well documented or understood. During the Petermann 2015 Expedition on the icebreaker Oden, seal and polar bear (Ursus maritimus) data were collected in Petermann Fjord (Northwest Greenland), the adjacent Nares Strait region, and transit to and from Thule, Greenland over 31 days (July 30 to …

Using Global Positioning System Technology To Manage Human-Black Bear Incidents At Yosemite National Park, Rachel L. Mazur, Ryan M. Leahy, Caitlin J. Lee-Roney, Kathleen E. Patrick
Human–Wildlife Interactions
Managing human–bear (Ursus spp.) incidents is a top management priority in national parks inhabited by bears. Yosemite National Park (Yosemite), located in the Sierra Nevada in California, USA, receives up to 5 million visitors annually. It is also home to 300–500 black bears (U. americanus). Yosemite has an extensive history of black bear research, educational programs, and innovative solutions for reducing human–bear incidents. Despite this, human–bear incidents peaked in 1998 at 1,584. The resulting political fallout led to Yosemite receiving funds to expand its bear management program, including increasing its staffing and garbage pick-up, and improving the …
