RT Monograph SR 00 A1 Gragnani, A. T1 Bifurcation Analysis of Two Predator-Prey Models YR 1994 FD 1994-08 SP 19 AB Bifurcation analysis is used to systematically detect unrealistic dynamic behaviors of two predator-prey models that have recently received support and attention. Comparisons with other existing models are also made, in order to show that the singularities of the two examined models are due to some biological weakness of their functional forms.
