Spatio-temporal chaos in a Holling-Tanner Predator-Prey Model with Holling type-IV functional response

Binayak S. Choudhury, Bankim Nasipuri


In this paper, we study a two dimensional spatio-temporal Holling-Tanner predator-prey model incorporating ratio-dependent Holling type-IV functional response. The emergence of Turing as well as non-Turing patterns are considered numerically. Our numerical experience suggests that the system is capable of producing different types of patterns including
spatio-temporal chaos with carefully chosen parameters from inside as well as from outside the Turing region.
