  In this work we investigate the influence of the dynamic state of galaxy
clusters on segregation effects and velocity dispersion profiles (VDPs) for a
sample of 111 clusters extracted from SDSS-DR7. We find that 73 clusters have
Gaussian (G) velocity distribution and 38 clusters have a complex or
non-Gaussian (NG) velocity distribution. We also split the G and NG samples
into 'active' and 'passive' galaxies, according to their sSFRs and stellar
masses. Our results indicate a strong spatial segregation between active and
passive galaxies both in G and NG systems, with passive galaxies being more
central. We also found that the passive population in G systems is the only
family with lower velocity dispersions for the brightest galaxies ($M_r
\lesssim -22.75$), thus presenting velocity segregation with luminosity. The
similarity found between the VDPs of the galaxy populations in NG systems
indicate that these sets probably share a similar mix of orbits. We also found
a clear evolutionary trend for G systems, with brighter galaxies in richer
clusters having flatter VDPs. The scenario emerging from this study suggests a
direct relationship between segregation effects, VDPs and the dynamic state of
clusters.
