Mating System

Members of the genus Cervus have polygynous mating systems within harems. These harems consist of several males, numerous females and their young offspring 1–3 years in age Members of this genus have a yearly breeding season where they display sensory exploitation, intrasexual competition, and weaponry. Females will fight for optimal mating opportunities and sexually selection for males with larger antler size and/or greater roar quality. The degree of polygyny and female aggregation is dependent on the level of food distribution. Females aggregating in areas with more food leading to larger harems Female distribution influences the level of polygyny.
