That is super generic! Did anyone else hear anything?
I wish their site would just inform you if you're rejected or not...I'm not sure that I'm even interested in Stanford anymore, but it would be nice to know!
You could also look into programs with animal geographers.
http://www.animalgeography.org has a list of mentors willing to help students that are interested!
Panic! (Jk)
Look into research interests of the faculty you're interested in working with and know how your research interests fit that. Also have a few questions prepared to ask them about the program. Maybe make a list of your experiences that give you an advantage over other applicants? Good luck!
