 - Obligate outcrossing mating strategy: the flower must be pollinated by pollen from another flower, and it must be done by an animal visiting. - Obligate outcrossing mating strategy: the flower must be pollinated by pollen from another flower, and it must be done by an animal visiting.

 - We will model the population of flowers instead of plants, i.e., considering one flower per plant. - We will model the population of flowers instead of plants, i.e., considering one flower per plant.

 - The plant has negligible costs in producing more nectar when it is depleted by the visitors (pollinators and nectar robbers) - The plant has negligible costs in producing more nectar when it is depleted by the visitors (pollinators and nectar robbers)

 - The production of nectar is proportional to the number of flowers - The production of nectar is proportional to the number of flowers

 - Specialized in the species of plant. The population can only grow with nectar consumption in the system. - Specialized in the species of plant. The population can only grow with nectar consumption in the system.

 - It has the behavior to increase the flower visit rates (and pollination) in searching for nectar when the amount of nectar per flower is low. But it has no cost for increasing the visitation rate. - It has the behavior to increase the flower visit rates (and pollination) in searching for nectar when the amount of nectar per flower is low. But it has no cost for increasing the visitation rate.
 +
 - It doesn't know how much nectar there is in the flower, so the pollinators can visit and pollinate the flower even though it has no nectar. - It doesn't know how much nectar there is in the flower, so the pollinators can visit and pollinate the flower even though it has no nectar.
 +
 - Pollinator growth rate related to nectar consumption has a saturation point, in which even though the nectar amount increases the number of pollinators does not increase anymore. - Pollinator growth rate related to nectar consumption has a saturation point, in which even though the nectar amount increases the number of pollinators does not increase anymore.
  
 **NECTAR ROBBERS** **NECTAR ROBBERS**
 +
 - Generalist species. They can robber nectar from other plants out of our system, but it is limited by a carrying capacity in the environment. - Generalist species. They can robber nectar from other plants out of our system, but it is limited by a carrying capacity in the environment.
 +
 - It consumes nectar from the flower competing by interference with the pollinators by nectar resources - It consumes nectar from the flower competing by interference with the pollinators by nectar resources
 +
 - Robbers don't know how much nectar there is in the flower, so it opens holes in flowers regardless of the amount of nectar. They damage (kill) flowers independently of the nectar amount. - Robbers don't know how much nectar there is in the flower, so it opens holes in flowers regardless of the amount of nectar.
