Factors that result in high vs low production may depend on carb
stores and total annual carbon assimilation. But can't the timing of
extreme weather events, (rain, frost, etc) that damage flowers or
prevent adequate pollination, result in near zero mast crops? If so
will the carbs saved from allocation to mast be used for structural
growth or allocated to next years reproduction? Or has this
hypothesis not been tested?

I was jogging on a pavement of burr oak acorns this September in
Minneapolis. Whether a mast year would have been predicted here,
or whether
other species should also have been masting, I have no idea.
