I find it difficult to see the connection - given the mechanism of recruitment - and that the bees come back once loaded up. Then there's the changing temperatures and the response of the flowers through the day, and flowers running out of nectar taken by bees. Can you get the modeller to make these connections or at least give the salient points of the model? -- James Kilty
