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

Restoration of the Iconic Pando Aspen Clone: Emerging Evidence of Recovery

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

The Role Of Predation In Disease Control: A Comparison Of Selective And Nonselective Removal On Prion Disease Dynamics In Deer

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

Saving large carnivores, but losing the apex predator?

Large terrestrial carnivores, e.g. wolves or bears, often play a key ecological role from their position at the apex of trophic systems. Changes to their populations reverberate through ecological communities; consequently their widespread decline in numbers and shrinking distribution due … read more

Socioeconomic Benefits Of Large Carnivore Recolonization Through Reduced Wildlife Collision

The decline of top carnivores has released large herbivore populations around the world, incurring socioeconomic costs such as increased animal-vehicle collisions. Attempts to control overabundant deer in the Eastern U.S. have largely failed, and deer-vehicle collisions (DVCs) continue to rise … read more
