摘要：
The present paper deals with the problem of a nutrient-phytoplankton (N-P) populations where phytoplankton population is divided into two groups, namely susceptible phytoplankton and infected phytoplankton. Conditions for coexistence or extinction of populations are derived taking into account general nutrient uptake functions and Holling type-II functional response as an example. It is observed that the three component systems persist when the infected phytoplankton population is not able to consume nutrient. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.
