(English) Zbl 1207.34106 Summary: A two-species predator-prey
system with stage structure and harvesting is investigated. The
existence of Hopf bifurcations for the system is proven. Also,
the stability and directions of the Hopf bifurcations are
determined by applying normal form theory and the center
manifold theorem. 34K60Qualitative investigation and simulation
