A trio of researchers, two with Universidad Austral de Chile, and one with Universidad Católica de Chile, has found that a gram of hibernating bat has a similar metabolism to a gram of hibernating bear. In their paper published in Proceedings of the Royal Society B, Roberto Nespolo, Carlos Mejias and Francisco Bozinovic describe their work in scaling energy expenditures of multiple mammals to learn more about the benefits of hibernation in general.
