In this paper. we investigate the dynamics of a discrete-time predator-prey system involving group defense. The existence and local stability of positive fixed point of the discrete dynamical system is analyzed algebraically. It is shown that the system undergoes a flip bifurcation and a Neimark-Sacker bifurcation in the interior of R+2 by using bifurcation theory. https://www.jmannino.com/hot-price-Reebok-Classic-Leather-Weiss-Grun-Gold-great-price/
