  The effects of mergers in low mass galaxies are poorly understood. In this
paper we analyze different observational evidences which support the view that
mergers can trigger starbursts in dwarf galaxies. We discuss the relationships
between blue compact galaxies (BCGs), dIs, dEs and low surface brightness
galaxies (LSBGs) and present some evidences which favour that strong starbursts
are caused by mergers between dEs and LSBGs.
