Social structure of Gnamptogenys bisulca (Formicidae: Ectatomminae) in tropical forests
Insectes Sociaux, 2019The study of the social organization of ants may help to understand why some species are able to persist in natural forests after fragmentation and anthropogenic disturbances. The Neotropical ant Gnamptogenys bisulca has shown to be a biological indicator of habitat quality in Andean montane forests and we proposed to explain this characteristic by ...
