Clusters of galaxies contain an overdensity of dwarfs compared to the field. Within galaxy clusters there is also a correlation between the overdensity of dwarfs and local galaxy density, such that areas of lower galaxy density contain more dwarfs per giant. The origin of these 'extra' dwarfs is

intermediate redshift revealed a large increase in the fraction of blue galaxies present. Spectroscopic studies have established the increased blue fraction is the re-sult of an increase in the fraction of galaxies which are actively forming stars in clusters at these redshifts (e.g. Dressler & Gunn 1982, 1983, 1992; Couch & Sharples

While the lensed, high redshift galaxies are the pri-mary interest of the HFF programme, many cluster mem-bers are also in the observations. Generally, cluster galaxies are quiescent, with little or no dust to produce FIR emis-sion. However, several Herschel studies have each detected 10s of cluster members at intermediate redshift (Rawle et al.

Internal kinematics of spiral galaxies in distant clusters

Galaxy clusters are important laboratories for understanding the origin of different morphological types of galaxies. The main reason for that is the relation between local galaxy density and morphological type (Dressler 1980). For nearby rich clusters, the spiral galaxy fraction decreases from 80% in the field to

Galaxy groups in this redshift range have been de ned with photometric data (de Mello Infante & Menanteau 1997) and with radio-galaxies as centers (1) but large, kinematically accurate redshift catalogs are needed to put intermediate redshift groups on the same standing as those at low redshift.
