From basic principles of positive/negative feedback control and classical density-dependent/independent population theory we outline a general explanation for the regulation of herbivore populations in forested ecosystems. We identify three fundamental patterns of behavior; (i) populations regulated close to equilibrium (“tight” regulation) by fast-acting negative feedback processes, (ii) populations regulated by delayed negative feedback processes (“loose” regulation) which often exhibit wide… CONTINUE READING
