Re: Bringing Back Mammoths (was Dinosaur Mating Displays)



There are other possible candidates for this kind of rejuvenated historic 
ecosystem. Although the theory has been challenged, Temple in 1977 suggested 
that the large fruits of the Calvaria major tree on Mauritius had once depended 
on the digestive abilities of dodos for breaking down the hard outer pit that 
had to be eliminated for the tree's germination to occur. If dodos were back 
(and you could get rid of the rats, pigs and other introduced species that ate 
dodo chicks and eggs), this and the Island's other beleaguered flora might 
benefit. Paul Martin has also pointed out that some extinct Pleistocene 
megafauna, like ground sloths, mammoths and some others, might have played a 
key role in propagating certain plants, and maintaining floral diversity, in 
the Southwest.  --Mark Hallett
