Query: Collective Behavior of Coupled Chaotic Maps   The collective behavior of a coupled map lattice having {\it unbounded}
chaotic local dynamics is investigated through the properties of its mean
field. The presence of unstable periodic orbits in the local maps determines
the emergence of nontrivial collective behavior. Windows of collective
period-two states are found in parameter space.
