All species interact. How species interact determines the health and stability of our vital ecosystems. Researchers use models to help understand biodiversity patterns in time and space and their vulnerability to environmental changes. Rarely do these models include species interactions. An important interaction for the successful functioning of our ecosystem is between flowering plants and their bee pollinators. I will use current knowledge and different modelling approaches to make better predictions of where wild bees occur and the flowers they interact with now and in the future, to aid scientific understanding of species interactions in general and improve conservation planning.
