We introduce our project that investigates the kinematic properties of early–type galaxies in 6 distant poor clusters at and Faber–Jackson relations. With the line strength diagrams age/metallicity distributions can be derived in densities between the field and rich cluster environments. Comparing with our rich clusters at the same cosmic epochs, the dependence of galaxy formation models on the local environment can be tested more quantitatively.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
