     The paper by Knapp et al., 2005, makes a very good case that 
long-distance dispersal of Nothofagus has occurred over the Tasman Sea.  
Nothofagus apparently doesn't like sea-water, but why has dispersal by 
migrating birds been rejected as a mechanism in the past?  Even if 
Nothofagus nuts are not eaten by birds today, perhaps they were eaten by 
some migrating species of bird which is now extinct.
