Reddit mentions of Game Theory and Animal Behavior

My undergraduate degree is in mathematics with a mathematical ecology concentration, and I love my current Ph.D. research. (I think it's hard to go wrong with a math major as an undergrad, if you're good at it -- you can use it for anything.) I'm planning to go into academia for a career, but depending on your specific interests there are all kinds of government or consulting jobs for good ecological modelers.

A few books on Amazon that may give you a taste for the field (any given person's specialty will more closely align with just one of them, but I'm trying to convey the broad options):

I'd recommend looking for some of these in your university library, then just browsing through everything next to them at the shelves and seeing if anything jumps out at you.
