Abstract: Our findings give new insight into the relationship between nestmate recognition and cleptobiosis, intraspecific thievery of newly collected food items, in a neotropical ponerine ant, Ectatomma ruidum. The expression of discrimination of nestmates from non-nestmates varied among local aggregations of E. ruidum in a population at Barro Colorado Island, Panama. This result is due to differences...
Body size is often positively correlated with ecologically relevant traits such as fecundity, survival, resource requirements, and home range size. Ant colonies, in some respects, behave like organisms, and their colony size is thought to be a significant predictor of many behavioral and ecological traits similar to body size in unitary organisms. In this study, we test the relationship between colony...
