For a sample of 34 X-Ray selected clusters taken from the X-ray Multi-Mirror (XMM) Large Scale Structure (LSS) survey, having uniform optical photometry from the CFHT Megacam g and r bands, the effects of both "global" and "local" environment on blue fractions were investigated. Clusters span the X-ray temperature range 1 less than kt(keV) less than12 and a relatively narrow range in redshift (0.15 less than z less than 0.14). Both showed results consistent with the proposed mechanisms of ram pressure stripping and galaxy-galaxy interactions through comparison with simple modelling.
