✦ Synopsis

We analyse an existing two variable model of predator-prey interactions. The analysis reveals problems in the model formulation. The main problem is related to the fact that the model is a mixture of empirically and causally based dynamic equations. An attempt to repair the model is made, but a completely satisfactory solution is not reached. We argue that model constructions, in which causal and empirical formulations are combined, contain fundamental problems.

The Beddington-DeAngelis ratio dependent prey predator model with time delay has been discussed. The existence of Hopf bifurcation has been established. The numerical simulations have shown that seasonal growth and delay can give rise to variety of attractors including periodic, quasi-periodic as we

## Abstract A predator–prey model is proposed within the general scheme of extended thermodynamics. An additional equation of balance is needed to account for the flux of the number density of the predator as an independent field variable. Copyright Β© 2002 John Wiley & Sons, Ltd.
