imperfect metabolism

    The story I heard is a little different.  The leaves are hypothesized to be 
a deterrant to herbivores that might nibble off the lower buds in winter.  I 
also heard a rumor that experimental evidence does not support this story, but 
noone has given me a good alternative and I have not seen a study in the 
literature.  I still like this explanation.
    Many other oaks besides reds keep their leaves: pin oaks, white oaks, post 
oaks, black oaks, to name a few.  I don't recall if chestnuts do.

My question is : Why red oak and young american beech keep theirs leaves 
in the winter ( I live near Montreal at the north of the U.S. )Somebody 
told me it's because oak and beech have an imperfect metabolism at the 
         Any response would be greatly appreciated and if you have 
reference book too.
