Notes:

  The number of racemes that had one or more open, untripped flowers in bloom is
  plotted over time since the bees were released in 7 commercial seed fields in
  1995 (Strickler and Freitas, 1999). Results demonstrate an initial burst of
  bloom, followed by an exponential decline in number of open flowers available
  for foraging bees.

  and bees in commercial alfalfa seed fields. Environ. Entomol. 28(2):
