Yeah there is info out there - I used to have a hardcopy of a paper on it. Quite staggering how resilient the little bastards are, and how responsive they are to population pressures. The phrase "cunning as a rat" didn't happen by accident! The self-management aspect of the species to respond to events outside their species' control is actually quite frightening, if an event causes them to run out of sufficient food they simply eat each other until things level back out...
