Since the Lotka-Volterra model was published, a lot of work has been devoted to studying the interactions between predator and preypopulations. In 2014, A. J. Terry proposed a new model [1], which isВ a generalization of the well-known Rosenzweig-MacArthur model [2]. In his model Terry removes the hypothesis of a constant death rate anda linear (with respect to the functional response) growth rate for the predator,that underline the Rosenzweig-MacArthur model (and other classical models).В This certainly makes the model more realistic.В
It should be mentioned, however, that a Holling Type-II functional response is used in the Terry's model.In [3] it is discussed that in many cases the Beddington-DeAngelis functional responceВ is to be preferred, since it gives a better fit to experimental data.Thus, we further modify the Terry's model by using theBeddington-DeAngelis functional response and study the behaviour of the solutions of the obtainedsystem.
