Conference publicationsBifurcations in Generalized Volterra Model of Two Trophic Levels EcosystemRussia, Pushchino A mathematical model of predator – prey microecosystem with lower critical population number of prey is considered. The predator – prey system is assumed under harvesting. Harvesting intensity variations generate changes in two model parameters which are considered as controllable. Bifurcation diagram in controllable parameters plane is constructed and corresponding phase portraits are represented. |
