Dynamics and pattern formations in diffusive predator‐prey models with two prey‐taxis
Authors:Xinxin Guo  Jinfeng Wang
Abstract:A reaction‐diffusion two‐predator‐one‐prey system with prey‐taxis describes the spatial interaction and random movement of predator and prey species, as well as the spatial movement of predators pursuing preys. The global existence and boundedness of solutions of the system in bounded domains of arbitrary spatial dimension and any small prey‐taxis sensitivity coefficient are investigated by the semigroup theory. The spatial pattern formation induced by the prey‐taxis is characterized by the Turing type linear instability of homogeneous state; it is shown that prey‐taxis can both compress and prompt the spatial patterns produced through diffusion‐induced instability in two‐predator‐one‐prey systems.
Keywords:global existence  predator‐prey  prey‐taxis  reaction‐diffusion  spatial patterns
