  The fluctuations due to the clustering of color sources can explain the
behaviour of the scaled multiplicity variance and transverse momentum
fluctuations with centrality. They also predict a nonmonotonic behaviour with
centrality for the multiplictiy associated to high pT events. The clustering of
color sources gives rise to an increase in the long-range correaltions with
centrality as well as to a supression at high centrality with respect to
superposition model predictions.
