Succession processes in a food web of a two autotroph one herbivore system

摘要

This paper deals with the succession process of a food web model consisting of one herbivore, two autotrophs and available nutrient in the environment in a closed nutrient flux. The model provides a way of describing successional changes in the form of species replacement with increasing nutrient levels. It is shown that distinct threshold (with upper and lower) values of nutrient are required for progression of succession process. (C) 2000 Elsevier Science Ireland Ltd. All rights reserved.
