Resources ≀ Benefits of Wolves

In May 2012, a lone wolf (Canis lupus) appeared in Victoria, British Columbia (BC), Canada, a metropolitan area on the southern tip of Vancouver Island with a population of 365,000 (Fig. 1A, B). After sightings in backyards over a few … read more

We are enduring the sixth mass extinction of life on our home planet. The Guardian UK recently reported on a study showing that ninety six percent of all mammals remaining on earth are humans and livestock. Only four percent are … read more

Predators and competitors of vertebrates can in theory reduce the density of infected nymphs (DIN)—an often-used measure of tick-borne disease risk by lowering the density of reservoir-competent hosts and/or the tick burden on reservoir-competent hosts. We investigated this possible indirect … read more

We combine model results with feld data for a system of wolves (Canis lupus) that prey on wild boar (Sus scrofa), a wildlife reservoir of tuberculosis, to examine how predation may contribute to disease control in multi-host systems. Results show … read more

Pando, the world’s largest living organism — and possibly its oldest — is being destroyed by the voracious appetite of mule deer.  According to the authors, “Humans have eliminated predators,” Without wolves prowling the area, deer populations not only explode, but … read more

Effective measures for controlling chronic wasting disease (CWD), a contagious prion disease of cervids, remain elusive. We review theoretic relationships between predation and hostparasite dynamics and describe a mathematical model to evaluate the potential influence of random removal through harvest … read more
