====='Landscape of fear': what a mass of rotting reindeer carcasses taught scientists===== | |||

When 323 reindeer were killed by lightning on a remote Norwegian plateau, their bodies were left for nature to take its course. | |||
Scavenger birds such as ravens, crows and eagles visited the highest density of carcasses in 2017 and then were nearly absent in 2018. The reverse was true of rodents (such as root vole, lemming, bank vole and field vole), which were absent from the site in 2017 and then were everywhere in 2018. Scientists believe rodents were too fearful to go to the site while these larger birds were around. Carcasses are interaction hotspots, but not all interactions are positive: “It’s kind of like, here’s a buffet, you’ve got a lot of hungry folks coming in to eat, and maybe they don’t like one another very much,” says Frank. | |||
