I'm sure someone more familiar with the research can express all of this mathematically and and confirm of deny the existance of an overall, cross-cutting model. It may even be common knowledge in evo bio/ecology/etc.
All I can mention on my phone right now is "keystone species", "s curve", and "wolf/rabbit populations". (or was it elk?) anyway, the latter search term leads to info on cyclical and highly dynamic ecologies. Check it out.
