The adaptiveness of worker demography in the attine ant Trachymyrmex septentrionalis

Castle theory states that worker size distributions in ant colonies have evolved for efficient division of labor and predicts that they should vary with habitat and have an effect on fitness. We tested these predictions in a comparative study of worker size variation and colony fitness in Florida an...
