Bifurcation analysis of a predator-prey model with predator intraspecific interactions and ratio-dependent functional response

作者：

Highlights：

• We presented the analytic and numerical analysis of the Bazykin predatorprey model with predator intraspecific interactions and ratio-dependent functional response.

• We studied different types of bifurcations, such as saddle-node bifurcations, Hopf bifurcations, homoclinic bifurcations and Bogdanov-Takens bifurcations.

• We studied the impact of changing the predator per capita consumption rate has on the basin of attraction of the stable equilibrium points.
