Polygyne is a term used to describe a social structure of certain ant species, where multiple queens live in a single colony. There are several synonyms that can be used to refer to polygyne, including "many-queened," "multicolonial," and "polygynous." These terms are often used interchangeably and describe the same social structure of having multiple reproducing queens per colony. Polygyne ant species have important ecological roles, such as influencing soil structure and nutrient cycling through their burrowing and foraging activities. These ants also play an important role in seed dispersal and pollination. Understanding the nuances between these synonyms can help researchers more accurately describe the social structures of different ant species and their ecological significance.
