Neurologgers are being used to investigate whether light pollution interferes with the circadian rhythms of tammmar wallabies, reports the New Scientist.
Studies using miniature sleep-recording devices known as neurologgers have already challenged several long-held beliefs about the sleeping habits of sloths and birds.
Three-toed sloths, for example, sleep far less than once thought. And male sandpipers can go almost entirely without sleep during the three-week breeding season, helping maximise their success at that time.
Now, John Lesku of La Trobe University in Melbourne and his colleagues are using neurologgers to investigate whether light pollution interferes with the circadian rhythms of tammar wallabies in Australia.
“The most obvious trait that you might think would respond to human light pollution is sleep, but there’s virtually no data on this,” says Lesku.
