In this work we explore signatures of evolution for the dark energy density X(z) = rho ( de )(z)/rho ( de )(0) using latest observations on SNIa and H(z). The models consist of parametrizations of the dark energy density and consequently a reconstruction for the EoS parameter w(z) as a function of redshift. Both parametrization methods using the SH0Es prior results in a small deviation from LCDM at 1 sigma for X(z). Extending the analysis up to 2 sigma, the evidence for evolution of X(z) dilute in both cases. We have also studied an interacting dark model where this trend is also found.
