COOPERAÇÃO, CONFLITOS E RAZÃO SEXUAL EM HIMENÓPTEROS SOCIAIS: A PERSPECTIVA DE UMA FORMIGA AMAZÔNICA

Abstract

*[The main aim of this paper is to brietly review 6 existing models dealing with asymmetrical sex ratios, highlighting their different assumptions and predictions. Data on the structure of Pheidole minutula (Myrmicinae) colonies, & their reproductive allocation pattern, illustrate how these models can be tested. The results support the hypotheses of Local Mating Competition, Split Sex-ratio and Resource Availability, but fail to corroborate both the Local Resource Competition and the Numerical Dominance hypotheses.]
