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

Occurrence and biogeographic aspects of Melipona quinquefasciata in NE Brazil (Hymenoptera, Apidae)
The stingless bee Melipona quinquefasciata is not included among the nine bee species of Melipona described in literature of NE Brazil. However, reports of some farmers raised suspicion on the occurrence of M. quinquefasciata in the state of Ceará, in NE

Melipona - Seis décadas de citogenética
São 59 anos de estudos citogenéticos no gênero Melipona e esse artigo é uma revisão dessa história, que vai desde trabalhos com apenas a determinação do número cromossômico, até os trabalhos de citogenética molecular. Os principais focos do artigo são: o número e morfologia dos cromossomos, conteúdo heterocromático e a natureza da cromatina.
