Trophic niche overlap and wild ungulate consumption by red fox and wolf in a mountain area in Italy.
"Red fox (Vulpes vulpes) and wolf (Canis lupus) are two widespread opportunistic predators living in simpatry. in many areas. Nonetheless, scarce information are available on their trophic interactions. We. investigated food habits of these two carnivores in a mountain area in Italy and assesse...
