We consider reaction-diffusion systems having a global attractor which collapses and turns to be a single stationary state by a perturbation. Although the dynamical structure largely changed by the perturbation, there is a perturbed orbit close to the unperturbed one during a transient time. In a specific reaction-diffusion system with conservation law we show for the perturbed system that a Turing-like wave takes place and it changes to a single spike, then the pattern finally collapses. The perturbed system has no longer steady state solutions which induce a Turing type instability. Nonetheless in the transient dynamics such a Turing-like pattern can be shown.
