Abstract: Lay SummaryLinks between behavioral traits can shift with the local climate. We show that behavioral associations with temperature not only occur across, but also within populations. At warmer sites ant colonies increased their exploration and foraging activity, but were less aggressive. Moreover, at these warmer sites, more positive links were found between behaviors within populations compared to colder sites, where more negative links prevailed. Our study suggests that associations between behaviors shift along climatic gradients.
