Researchers at Lund has filmed reindeer with infrared camera and explains why the overcast actually can shift in red.
film, taken with the infrared camera, shows clearly that renes mule is warmer than other parts of the body.
– When the reindeer eat in winter is their muzzles exposed to very low temperatures, as they search for food under the snow. They need to maintain their sensitivity in the cloudy so they know what they are getting into, says Ronald Kröger, professor of functional zoology at Lund University in a press release.
– The warm blood that is pumped to the reindeer mule can do that it gets a reddish “glow”.
Ronald Kröger is part of a research team that is studying how mammals acquire sensory information from the front, soft and wet part of the nose, also called for rhinarium.
idea for “Nosgruppen” (the Mammalian Rhinarium Group) got Ronald Kröger when he was playing with his dog and began to think about why a dog’s nose is so cold.
– Dogs works in the opposite way compared to the reindeer. No one knows why their noses are cold, and what is the evolutionary cause. We want to find out, says Ronald Kröger.
