In this work, we consider four different galaxy populations and two distinct
global environments in the local Universe (z $\leq 0.11$) to investigate the
evolution of transitional galaxies (such as star-forming spheroids and passive
discs) across different environments. Our sample is composed of 3,899 galaxies
within the R$_{200}$ radius of 231 clusters and 11,460 field galaxies. We also
investigate the impact of the cluster's dynamic state, as well as the galaxy's
location in the projected phase space diagram (PPS). We found that although the
cluster environment as a whole influences galaxy evolution, the cluster
dynamical state does not. Furthermore, star-forming galaxies represent recent
cluster arrivals in comparison to passive galaxies (especially in the case of
early-types). Among the ETGs, we find that the D$_n(4000)$ and H$_\delta$
parameters indicate a smooth transition between the subpopulations. In
particular, for the SF-ETGs, we detect a significant difference between field
and cluster galaxies, as a function of stellar mass, for objects with Log
$M_*$/M$_{\odot} > 10.5$. Analyzing the color gradient, the results point
toward a picture where field galaxies are more likely to follow the monolithic
scenario, while the cluster galaxies the hierarchical scenario. In particular,
if we split the ETGs into lenticulars and ellipticals, we find that the steeper
color gradients are more common for the lenticulars. Finally, our results
indicate the need for galaxy pre-processing in smaller groups, before entering
clusters.
