Animal personality research often overlooks social insects. This study reveals that greater behavioral variation within ant colonies (Temnothorax longispinosus) boosts productivity, highlighting the adaptive significance of collective personalities.
Area of Science:
- Behavioral ecology
- Social insect behavior
- Evolutionary biology
Background:
- Animal personality research has primarily focused on solitary species, leaving the adaptive significance of collective personalities in social insects underexplored.
- Intracolonial behavioral variation is crucial for the division of labor and societal success, yet empirical links to fitness are scarce.
Purpose of the Study:
- To investigate the adaptive significance of intercolonial and intracolonial behavioral variation in Temnothorax longispinosus ant colonies.
- To examine the consistency of aggression, exploration, and brood care behaviors over time and across contexts.
- To determine the influence of intracolonial behavioral variation on colony productivity.
Main Methods:
- Assessed aggression, exploration, and brood care behaviors in ant colonies over several months.
- Examined consistency of behaviors across time and in response to experimental sequences.
- Quantified intracolonial behavioral variation and its correlation with colony productivity under standardized conditions.
Main Results:
- Aggressiveness showed consistency over time, while other behaviors varied.
- Exploration behavior was influenced by prior experimental context (aggression assays).
- Colonies with higher intracolonial variation in brood care and exploration exhibited greater productivity.
Conclusions:
- Behavioral syndromes were not consistently maintained over time in these ant colonies.
- Intracolonial behavioral variation, particularly in brood care and exploration, is positively linked to colony productivity.
- Findings underscore the adaptive importance of behavioral diversity within social insect colonies.
