  Dynamical fluctuations of the globally conserved quantities in heavy ion
collision such as baryon number, strangeness, charge, and isospin are suggested
to carry information about the deconfinement and chiral phase transitions. The
STAR experiment has performed a comprehensive study of the collision energy and
charge dependence of dynamical particle ratio ($K/\pi$, $p/\pi$, and $K/p$)
fluctuations, net-charge fluctuations, and transverse momentum correlations at
mid-rapidity, as well as neutral-charge pion fluctuations at forward rapidity.
The centrality, charge, and collision energy dependence from new measurements
of the fluctuation observables $\nu_{dyn}$ and $r_{m,1}$ and the energy
dependence of transverse momentum correlations from $\sqrt{s_{NN}}$ = 7.7-200
GeV Au+Au collisions are presented. These results are also compared to
predictions from hadronic models.
