|dc.description.abstract||Integrodifference equations are discrete-time analogues of reactiondiffusion equations and can be used to model the spatial spread and invasion of
non-native species. They support solutions in the form of traveling waves, and
the speed of these waves gives important insights about the speed of biological
invasions. Typically, a traveling wave leaves in its wake a stable state of the
system. Dynamical stabilization is the phenomenon that an unstable state
arises in the wake of such a wave and appears stable for potentially long periods
of time, before it is replaced with a stable state via another transition wave.
While dynamical stabilization has been studied in systems of reaction-diffusion
equations, we here present the first such study for integrodifference equations.
We use linear stability analysis of traveling-wave profiles to determine necessary
conditions for the emergence of dynamical stabilization and relate it to the
theory of stacked fronts. We find that the phenomenon is the norm rather
than the exception when the non-spatial dynamics exhibit a stable two-cycle.|
