Wolves have their own way of communicating: they howl.
Scientists of the Messerli Research Institute at the University of Veterinary
Medicine, Vienna (Vetmeduni Vienna) in collaboration with scientists of the
Universities of Zürich and Parma have investigated what drives this form of
vocalization. When individual wolves are separated from the pack, the intensity
of howling of each remaining pack member is determined by the relationship
between the separated wolf and the howler, while emotional stress is less
important. The results are published today in the prestigious journal Current
Biology.
