To understand the effect of urbanization on the biological com- munity in the arid region, we studied the ant community along urbanization gradients in Wadi Hanifa in Riyadh, central Saudi Arabia. We found consistency in diversity parameters (abundance, richness, evenness, and Shannon and Simpson diversities) across the urbanization gradient. How- ever, we observed discrete differences in ant community structure across the urbanization gradi- ents. Environmental factors such as vegetation type, soil properties and ground cover proved to be important determinants of ant species composition.
