hi redstripedzebra again,
well I am glad that my answer help, firts of all research is a great idea because my masters degree helped me alot in getting in school in PEI, for the GRE thing I do not really know , but I know the bets thing to do in these cases is to pick upithe phone and phone them direct. always follow this theory when it comes to getting infomrations, it is the best way to get informations.
Your research is in comparative physiology is a very good idea and I think it will help you there too.also for your wildlife experience may be if you try Toronto zoo they might let you do some work there.
good luck and do not histitate to ask.
Regards
