Restoring oceanic islands' ecosystems by controlling introduced predator species

In this paper, we analyze a predator-prey model of oceanic islands with switching strategy of opportunistic superpredators. The essential mathematical features are analyzed with the help of equilibrium local and global stability analysis. We find seven equilibrium possibilities and establish conditions under which the three species, prey (birds), mesopredator (rabbits) and superpredator (cats), coexist. Moreover, we discuss ways to save the bird population. Experimental data simulation and brief discussion conclude the paper.
