blooming pattern: another variable?

Howdy All,

Just to raise another variable re flowering times....... it would 
also greatly depend upon what pollinators are about.  If the desired 
pollinators were only in the area in autumn (for example) then those 
individuals of a species that flowered in spring or summer would not 
be pollinated, and therefore note reproduce...... which is a dead end 
result.  Those that flowered in autumn when the desired pollinators 
were available would reproduce, so eventually only those plants in 
that genus that had the genetics right for flowering in autumn would 
be in existence in the area.  Effectively a form of survival of the 
fittest, or at least survival of the "pollinator timing" fittest anyway.

Just another thought to throw into the mix.  It would obviously 
depend on plant types etc, which of course determines what sorts of 
pollinators would be needed, but it could possibly be a factor in the 
whole puzzle couldn't it?  This is just a hypothesis of mine, so I 
have no idea of whether there is empirical data to support it....... 
'twas just an idea of mine that I thought I might contribute.

I hope this makes sense to those who are reading it. <grin>
