Tendency towards Gigantism with colder climates...

[ktorigai@xxxxxxxxxxxxxxxx (kaori torigai)]

     I am currently working on researching for a seminar for a third
year Evolutionary Paleoecology class.  My topic is the correlation
between size and climate, re:  the tendency towards gigantism as the
climate becomes colder.  For example, why mammals seem to have gotten
larger during glacials and tended to get smaller during the
interglacials?  I was wondering if anyone has any good
references on why this occurs, or any other relevant information. 
Please get in touch ASAP if you have any ideas....Thank you very much!
