Green bridges in a re-colonizing landscape: Wolves (Canis lupus) in Brandenburg, Germany
Gray wolves (Canis lupus) are recolonizing many parts of central Europe and are a key part of international conservation directives. However, roads may hinder the reestablishment of gray wolves throughout their historic range by reducing landscape connectivity and increasing mortality from wildlife-...
