Ambient temperatures (Ta) and soil-surface temperatures (Ts) at which ten species of ants were active were recorded over a two-year period in the southern Karoo. There were significant differences in the mean Ts at which the different species were active, with seed-harvesters generally active at lower Ts than predators. Overall mean Ta at which ants were active ranged from 20,7 ï¿½C in the large seed-harvester Messor capensis to 28,8ï¿½C in the predator and scavenger Ocymyrmex cilliei.
