Subject: A Career in Biology?

I am researching a career in Biology, specifically Field Biology if I can find 
enough information.  I have a few questions, and I would appreciate any help.

1)How selective is field biology compared to other areas of biology?  I have 
read that most biologists work as teachers and professors or work as 
assistants in labs, but I am interested in data collection and research 
outside the lab as well.  Would it be more difficult to get a job if research 
is what I want to do?

2)Are there any specific things that I can do gain an "edge" to help with a 
career in field biology?

3)I am also very interested in working with animals.  Is field biology 
involving animals (beyond using them as experimentation tools) the same as 
zoology?

4)Are there any other names for Field/research biology?

5)I intensely dislike dissection, but I can learn to live with it.  Can you 
estimate the number that I will probably have to do?
