Anyone who has seen a hummingbird poking her beak deep into a trumpet creeper blossom, or a honeyeater using its brush-tipped tongue to extract nectar from eucalyptus flowers, has witnessed something that, from a human perspective, is rather remarkable. Although many bird
Though previous research has shown that bird populations are declining across North America, a new study is the first to show that the pace of loss has picked up speed since the mid-1980s in three regions: the Midwest, California and Mid-Atlantic states. The work appears in
Researchers from the University of Oxford, Nanjing Agricultural University, and Institute of Genetics and Developmental Biology (Chinese Academy of Sciences) have finally identified the master regulator in plants that balances root and shoot growth when nutrients are limited.
And what that says about their prowess as communicators The post How Horses Make Two Sounds at Once appeared first on Nautilus .
Birds that feed on nectar or fruit evolved better mechanisms for managing metabolism, blood pressure and high glucose.
Why does your dog rush to "help" when you are searching for something, while your cat seems… eh, less concerned? New research suggests that this difference may stem from deep evolutionary roots—and that, in certain situations, dogs behave more similarly to young children than
