Huddling: brown fat, genomic imprinting and the warm inner glow.” Current Biology 18(4): R172-R174.0960-9822http://nrs.harvard.edu/urn-3:HUL.InstRepos:11148776Heat generated by huddling animals is a public good with a private cost and thus vulnerable to exploitation, as illustrated by recent work on rabbits and penguins.
