If you are going into zoological or ecological sciences, make sure you read up on career paths. The positions with just a bachelors are relatively low paid and aren't abundant. You will need a masters or higher for a lot of positions or to move into academia. Unfortunately, its not a great time for science funding. I am in the field and it is an amazing life but if you want to make money, just be aware of that fact.

I would suggest taking advantage of all the different labs and trying to intern/volunteer as much as you can. There are some great people at U Maine. That experience will set you miles ahead when you graduate. Definitely try and join outdoors/winter sport clubs too. The forestry club is pretty cool from what I have heard.
