A Socio-Ecological Approach to Wildlife Disease Risk
Many Eastern moose (Alces alces, Linnaeus; 1758) populations along the southern edge of their North American range are declining, including those in Minnesota, Vermont, and New Hampshire. More recently, in Maine, winter ticks (Dermacentor albipictus; Packard 1869) are suspected to also be influencin...
