  Luminous Compact Blue Galaxies (LCBGs) are a heterogeneous class which
dominate an intermediate phase of galaxy evolution. These sources account for
the majority of the star formation between 0.3<z<1, yet the identity of their
present-day counterparts is an open question. An environmental dependence to
their evolution may provide the answer. We have undertaken the first census of
LCBGs in intermediate-redshift clusters using broad and narrow-band images from
the WIYN Long Term Variability Study. Several key clusters are in the southern
sky. The Southern African Large Telescope's (SALT) Prime Focus Imaging
Spectrograph (PFIS), with a field of view matching our WIYN data, will allow us
to determine several fundamental characteristics of cluster LCBGs, including
(1) star formation rates (SFR) and metallicities from low dispersion
Mulit-Object Spectroscopy (MOS); (2) dynamical masses from line-widths measured
via high dispersion MOS; and (3) cluster velocity dispersions of LCBGs relative
to other cluster emission-line galaxies via Fabry-Perot imaging or MOS. We
tentatively connect these distant galaxies with their local, evolved
counterparts, and discuss how PFIS observations will enable us to make the
physical distinction between LCBGs in clusters and the field.
