in the Presence of Predator Interference

Abstract: The present study deals with a
prey- predator model where the prey can freely move within two habitats and the
predator can switch to the habitat with most abundant species. The predation has
been studied in the presence of predator interference. The stability analysis
has been carried out for non zero equilibrium values. Conversion rate of the
prey to predator has been taken as a bifurcation parameter and for select data
sets, bifurcation points have been found. Interestingly, contrary to the earlier
work, all the three types of situations, namely – no bifurcation, single and
multiple bifurcations exist.
