Spatial compartmentalization: A nonlethal predator mechanism to reduce parasite transmission between prey species

Predators can modulate disease transmission within prey populations by influencing prey demography and behavior. Predator-prey dynamics can involve multiple species in heterogeneous landscapes; however, studies of predation on disease transmission rarely consider the role of landscapes or the transmission among … read more

Wolves make roadways safer, generating large economic returns to predator conservation

Recent studies uncover cascading ecological effects resulting from removing and reintroducing predators into a landscape, but little is known about effects on human lives and property. We quantify the effects of restoring wolf populations by evaluating their influence on deer–vehicle … read more

Staqeya: the lone wolf at the edge of its ecological niche

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

Partnering with gray wolves to solve the conservation crises of our time

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

Cascading effects of predator activity on tick-borne disease risk

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

Wolves contribute to disease control in a multi-host system

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
