Wolves in Utah: An analysis of potential impacts and recommendations for management
The historic range of gray wolves (Canis lupus) in Utah was essentially statewide. Although their presence cannot be disputed, the historic abundance of wolves in Utah is unknown. The release of gray wolves into Yellowstone National Park and central Idaho in 1995 established growing populations, and increasing dispersal is bringing these wolves closer to Utah. It seems likely that wolves will commingle with Utah\u27s other native mammals in the near future. The potential presence of wolves in Utah is generating a series of questions and debates. In this report, we review the potential of wolves in Utah and make predictions regarding the social and economic impacts of wolf recolonization on the livestock industry, on hunter success, and on wildlife managers, and then make recommendations on possible ways to mitigate these impacts
Economic aspects of wolf recolonization in Utah
An assessment of likely economic effects of wolf recovery should be included in the discussion of the future of wolves in Utah. In this section, we discuss both the potential benefits and the expected costs of wolf recovery to Utah’s economy. The potential benefits include both use—such as increases in tourism resulting from the presence of wolves—or non-use values that can be measured by willingness to pay surveys. The expected costs of recovery include direct costs born by agencies involved in wolf management, livestock owners that experience losses from wolf depredation, and those that might result from reduced game take by hunters. In addition, there may be indirect costs, which are more difficult to quantify
Biological aspects of wolf recolonization in Utah
Wolves have been one of the most scientifically examined of all wildlife species (Mech, 1995b). Many studies have focused on the effects of wolf reintroductions and recolonization. In this section, we address how wolves may naturally disperse into Utah, highlight areas identified in our habitat model as constituting the most favorable wolf habitat in Utah, estimate potential wolf populations in Utah, and describe what is currently known about the influence of wolves on an ecosystem
Potential strategies for managing Utah\u27s wolf-livestock conflicts
The United States Fish and Wildlife Service (USFWS) classifies gray wolf populations as either endangered, threatened, or nonessential / experimental. Therefore, if wolves enter Utah under their current legal classification, the USFWS will be the primary agency responsible for wolf management (see Section 2). For the last 30 years, this agency has been responsible for managing recovering wolf populations in other parts of the United States, both in the Great Lakes and the Rockies. Unfortunately, wolves have come into conflict with livestock in all of their recovery areas. As a result, the USFWS has taken various measures to minimize these conflicts, while maintaining their objectives to continue to recover wolf populations
Immunotherapeutic targeting of membrane Hsp70-expressing tumors using recombinant human granzyme B
Background: We have previously reported that human recombinant granzyme B (grB) mediates apoptosis in membrane heat shock protein 70 (Hsp70)-positive tumor cells in a perforin-independent manner
