Artificial Lights and Bat Drinking Behavior

Darkness is a diminishing natural resource. Over the last hundredyears, human development and urbanization have changed the nocturnallandscape, making the nighttime sky 20 percent brighter.

This is bad news for nocturnal animals like bats, which depend on the protection offered by darkness. In my latest Animal Minds blog post, I take a look at how artificial lighting affects bat drinking behavior.
