Abstract
Heat 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. Effects of imprinted genes on brown adipose tissue suggest that non-shivering thermogenesis is an arena for intragenomic conflict.
