Small, isolated populations are driving inbreeding in Norway’s wild reindeer, leaving them increasingly vulnerable. New DNA analyses also reveal extensive genetic mixing with semi-domesticated reindeer.

Inbreeding threatens the Fennoscandian Arctic fox. In a recent report from the Norwegian Institute for Nature Research (NINA), researchers propose measures to ensure the long-term survival of the species.

1.9 billion invertebrates and 800 million seeds. That’s the number of stowaways arriving to Norway via garden plants every year. The costs could be sky high.
