- | Indeed, some studies suggest that the reproductive success of burrowing owls increase with the density of burrows abandoned by mammals. | + | Indeed, some studies suggest that the reproductive success of burrowing owls increase with the density of burrows abandoned by mammals, because more nesting and roosting sites are avaliable. Also, owls can benefit from higher densities of nests by increasing predator alertness, as they can hear more easily alarms from their neighbors. |

+ | Propose a mathematical model for the coupled population dynamics of burrowing owls and of at least a prey or a predator of the owls. Your model should take into account the indirect effects of preys (and/or predators) by providing burrows for the owls. Use this model to explore the consequences of such indirect effects. | ||
