Number of pollinators. a) Evolution of the number of pollinators in the network during the season. For both years, the number of pollinators increases until a few days before the end of the season where it collapses suddenly. At the same time, the number of pollinators leaving the network peaks. b) Shown is the estimated sigmoid shape of the parameter p(x) (see Methods, Analysis and modelling) for the removal of insects in 1996 and 1997. 'Day' is the good days.
