Forests glow under UV light, and deer can see it
When a predator like a lion walks through the grasslands, it makes its presence known by roaring, which can be heard miles away. Since the lion is at the top of the food chain, it doesn’t particularly require privacy. But for animals like deer, making loud sounds isn’t exactly the safest way to communicate. So, to get noticed, deer mark areas with rubs and scrapes, known as signposts. Now, a new study in Ecology and Evolution reports that these signposts hold a hidden glow, and other deer can see it.
