A Comparison of Facial Color Pattern and Gazing Behavior in Canid Species Suggests Gaze Communication in Gray Wolves (Canis lupus)
June 15, 2019
As facial color pattern around the eyes has been suggested to serve various adaptive functions related to the gaze signal, we compared the patterns among 25 canid species, focusing on the gaze signal, to estimate the function of facial color … read more

Sedentary But Not Dispersing Wolves Canis Lupus Recolonizing Western Poland (2001–2016) Conform to the Predictions of a Habitat Suitability Model
June 15, 2019
The HSM for Polish wolves predicted with high accuracy the areas later occupied by wolf groups in the western part of the country. A similar approach may also be useful to predict the future distribution of wolves in the lowlands … read more

Was that a Wolf or Coyote?
June 15, 2019
Distinguishing between coyotes, wolves, and dogs. Wolf pups in mid-summer and fall can closely resemble coyotes, and it can be nearly impossible to tell them apart. Distinguishing dogs from wolves can be challenging. Many of the traits possessed by wolves can … read more

Top Predators Constrain Mesopredator Distributions
June 15, 2019
Top predators can suppress mesopredators by killing them, competing for resources and instilling fear, but it is unclear how suppression of mesopredators varies with the distribution and abundance of top predators at large spatial scales and among different ecological contexts. … read more
