Evaluating Moose Alces Alces Population Response To Infestation Level Of Winter Ticks Dermacentor Albipictus, Daniel D. Ellingwood, Peter J. Pekins, Henry Jones, Anthony R. Musante
Evaluating Moose Alces Alces Population Response To Infestation Level Of Winter Ticks Dermacentor Albipictus, Daniel D. Ellingwood, Peter J. Pekins, Henry Jones, Anthony R. Musante

Many wildlife populations are experiencing a variety of environmental pressures due to the direct and indirect consequences of a changing climate. In the northeast, USA, moose Alces alces are declining in large part because of the increasing parasitism by winter tick Dermacentor albipictus, facilitated by high host density and optimal environmental conditions. To test this hypothesis, and better understand the influence of this interaction on the stability of the regional population, we constructed a population viability model using data collected through comprehensive survival and productivity studies in 2002–2005 and 2014–2018 in northern New Hampshire. Years of heavy tick infestation (epizootics) …

Assignment Of Measurable Costs And Benefits To Wildlife Conservation Projects, S. A. Shwiff, A. M. Anderson, R. Cullen, P. C. L. White, S. S. Shwiff

Success of wildlife conservation projects is determined by a suite of biological and economic factors. Donor and public understanding of the economic factors is becoming increasingly central to the longevity of funding for conservation efforts. Unlike typical economic evaluation, many costs and benefits related to conservation efforts are realised in nonmonetary terms. We identify the types of benefits and costs that arise from conservation projects and examine several well developed techniques that economists use to convert benefits and costs into monetary values so they may be compared in a common metric. Costs are typically more readily identifiable than benefits, with …
