Some people think they're spooky and sinister, but bats play a critical role in maintaining California's ecosystem as well as the state's valuable agriculture industry. Now climate change is threatening their populations.They sleep during the day, begin to hunt as night falls, and often terrify people. However, there's nothing creepy about what bats do for the environment.
'The way animals move is very dependent on how the climate is behaving,' said Levi Souza, a senior environmental scientist with the California Department of Fish and Wildlife.His team is tracking bats by attaching small radio transmitters to them. It's part of an international research network called Motus.
