The cause of varying galaxy interaction outcomes in different environments is investigated using a sample of over 505,000 Sloan Digital Sky Survey Data Release 7 galaxies at 0.01 < z < 0.20. The aim is to distinguish the large-scale environmental effects on galaxies from the small-scale interaction effects in order to identify whether interaction mechanisms vary in different environments, or whether different galaxy populations produce the various outcomes in different environments.
