In order to empirically determine the timescale and environmental dependenceof stellar cluster disruption, we have undertaken an analysis of theunprecedented multi-pointing (seven), multi-wavelength (U, B, V, H$\alpha$, andI) Hubble Space Telescope imaging survey of the nearby, face-on spiral galaxyM83. The images are used to locate stellar clusters and stellar associationsthroughout the galaxy. Estimation of cluster properties (age, mass, andextinction) was done through a comparison of their spectral energydistributions with simple stellar population models. We constructed the largestcatalog of stellar clusters and associations in this galaxy to-date, with ~1800sources with masses above ~5000 M$_{\odot}$ and ages younger than ~300 Myr. Inthe present letter, we focus on the age distribution of the resulting clustersand associations. In particular, we explicitly test whether the agedistributions are related with the ambient environment. Our results are inexcellent agreement with previous studies of age distributions in the centre ofthe galaxy, which gives us confidence to expand out to search for similaritiesor differences in the other fields which sample different environments. We findthat the age distribution of the clusters inside M83 varies strongly as afunction of position within the galaxy, indicating a strong correlation withthe galactic environment. If the age distributions are approximated as apower-law of the form $dN/dt \propto t^{\zeta}$, we find $\zeta$ values between0 and -0.62 ( $\zeta$~-0.40 for the whole galaxy), in good agreement withprevious results and theoretical predictions.
