Abstract: Prey-predator models can exhibit various forms of pattern formation. Spatio-temporal dynamics of prey-predator systems are relevant for several ecological applications. Spatial synchrony is one manifestation among a broader array of space-time patterns. In this work, we study the synchronisation of spatio-temporal dynamics via a control approach based on modelling error compensation ideas. Numerical simulations on two spatio-temporal models of prey-predator interactions, coupled and distributed parameter systems, are used to illustrate our findings.

Keywords: prey-predator interactions; spatial synchrony; reaction-diffusion equations; coupled oscillators; modelling error compensation; MEC; spatio-temporal dynamics; coupled parameter systems; distributed parameter systems; ecosystem dynamics; ecosystems; spatial interacting populations; feedback control.
