I'm social psychologist and my knowledge in ethology and animal behavior literature is very limited. I’m currently working on comparative project on collective violence and the idea of comparison of ant and man social behavior seems very tempting. I’ve read several experimental and natural observation papers and the field seems very interesting. I’m looking for a review paper or a book that summarizes all lines of inquiry and relatively up to date knowledge on the subject of inter colony conflicts. I would be very grateful for any hints.
