Tragedy of the commons in Melipona bees\ud [PDF]

open access: yes, 2004
In human society selfish use of common resources\ud can lead to disaster, a situation known as the ‘tragedy\ud of the commons’ (TOC). Although a TOC is\ud usually prevented by coercion, theory predicts that\ud close kinship ties can also favour reduced exploitation.\ud We test this prediction using data on a TOC\ud occurring in Melipona bee societies.
