Predator-prey relationships are one of the most studied interactions in
population ecology. However, little attention has been paid to the possibility of
role exchange between species, despite firm field evidence of such phenomena in
nature. In this paper, we build a mathematical model capable of reproducing the
main phenomenological features of role reversal in a classical system and present
results for both the temporal and spatio-temporal cases. We show that, depending
on the choice of parameters, our role-reversal dynamical system exhibits
excitable-like behaviour, generating waves of species' concentrations that
propagate through space. Our findings fill a long-standing gap in modelling
ecological interactions and can be applicable to better understanding ecological
niche shifts and planning of sustainable ecosystems.
