“Wolves like cherry-picking”: Modelling shows how they recolonized Germany and where they could live in the future

A team of scientists from the Leibniz Institute for Zoo and Wildlife Research found that grey wolves' habitat selection changes during recolonization in Germany, moving from early-stage 'cherry-picking' to late-stage less-selective choices. This shift affects predictions of wolf distribution and expansion in the country.
