Competition can be for access to mates or reproductive resources such as food, or nesting areas. Female-female aggression in ungulates is often overlooked because it is not as extravagant as male antler combat. Female conflicts occur so the winner has first access to the harem male at the start of the mating season before he is exhausted or low on sperm storage.
Competition for mates or reproductive resources, such as food, nesting areas, can be a driving force in animal behavior. Female-female aggression in ungulates is often overlooked because it's not as visually dramatic as male antler combat.  Female conflicts arise to secure access to the dominant male at the start of mating season before he becomes depleted or his sperm reserves are exhausted.
