We investigated the galaxy morphology of 6 Abell clusters at z = 0:0784 - 0:145 based on deep images obtained using MegaCam on the CFHT. For hundreds of galaxies in our data, we classified their mor- phology based on criteria related to secular or merger related evolution. We found that the morphological mixture of galaxies varies considerably from cluster to cluster. This article contains a general description of our deep imaging campaign and preliminary results for galaxy morphologies in cluster environments.

We performed statistical analysis for a nearby (0.01 < z < 0.05) volume limited (Mr < —19) sample of galaxies via visual inspection and the definition of galaxy pair systems based on the Sloan Digital Sky Survey Data Release 7 in order to conrm the effects of galaxy interaction on AGN activities. We found that local environmental effects such as galaxy interaction have an in uence on the enhancement of the frequency and the strength of the AGN activity. This article is the summary of the paper which will be submitted soon.
