 Hey Peter- I have not seen the papers either, but offhand the logic seems
all backwards.  Shouldn’t the question be about what resources a pollen
grain needs to do its thing, and how to package that?  The former seems
obvious.  The latter comes to mind for a lot of buzz-pollinated pollens,
which tend to be dry with little pollenkitt (so the respond to buzzing?),
and so their contents are concentrated.  Or so I expect.  Since there has
yet to be evidence that bees can judge protein content of pollen, that
source of selection remains speculative even if it were plausible.
