"Political unrest doesn’t just destabilize governments—it can also hurt wildlife. A new study finds that large mammal populations declined rapidly following the collapse of the Soviet Union...The analysis uncovered major changes in population growth; with the exception of wolves, all species experienced a drop in population growth rates immediately following the collapse, and three species—wild boar, moose, and brown bears—exhibited significant reductions in population growth throughout the decade following the collapse, with declines evident in 85% or more of the study regions."
