But how this constraint is dealt with can differ between human and wildlife populations. When the panther population gets large enough the food may become insufficient, leading to competition among panthers, from this competition, panthers may starve, or die, and stop reproducing. For this example, we introduce the relationship between barnacles and oysters. These key factors have the ability to limit, or even reduce a population by lowering birth rates, increasing the death rate, or encouraging migration.
