Social Living Mitigates the Costs of a Chronic Illness in a Cooperative Carnivore

Infection risk is assumed to increase with social group size, and thus be a cost of group living. We assess infection risk and costs with respect to group size using data from an epidemic of sarcoptic mange (Sarcoptes scabiei) among … read more

Wolves Have Local Howl Accents

Understanding the regional vocal patterns of various canid species sheds light on animal communication and could help ranchers broadcast “keep away” messages to protect livestock.

Wolves Adapt Territory Size, Not Pack Size to Local Habitat Quality

Although local variation in territorial predator density is often correlated with habitat quality, the causal mechanism underlying this frequently observed association is poorly understood and could stem from facultative adjustment in either group size or territory size. To test between … 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
