Dear Frances
 
Thanks for your reply. Yes I've been surprised by the apparent lack of the
calculation. I've been able to establish a maximal proportion of around
0.18 by using the usual statements about length of life as a forager and
the ususal onset of foraging, but this seems far too low to my co-worker
who is a beekeeper. If I double the lifespan of the forager and set a
comparatively early onset of foraging it comes out at about 0.34.
 
I'd appreciate the reference to your thesis and a copy of the abstract, if
you dont mind me quoting it in a review of honey bee impacts on protected
natural areas in New Zealand.
 
I'm curious. Are you the Ratneiks who provided a chapter of selection at
the colonising front of African Bee invasions in Marla Spivaks book? If so,
congratulations! I think it isa very important contribution to invasion
biology in general.
 
Thanks for your reply,
 
Cheers
 
Henrik
