Introduced herbivores and the Allee effect in animal-pollinated plants Ecología austral
Vázquez,Diego P.
Interspecific interactions can be modulated by the community context in which they occur. In this paper I focus on plant-pollinator interactions and their modulation by introduced herbivores through changes in plant population density. I first develop a mathematical model that relates the population density of an animal-pollinated plant species with pollinator visitation frequency, pollination, reproduction and per capita growth rate. This model allows me to investigate how several pollination-related parameters -including relative abundance of the focal plant species, pollinator specialization, pollination quantity and quality and pollen limitation of reproduction- influence the relationship between per capita growth rate and population density. I then...
