Dwarf galaxies in the local group provide a unique astrophysical laboratory.\nIn particular, they allow us to probe pulsating (and other) variable stars in\nlow-metallicity environments with abundances below that of the SMC. Our\nobserving program, described in detail by C. G "ossl's contribution, yields a\nlarge number of intrinsically bright variable stars that can serve as probes of\nthe stellar population and star formation history of these galaxies. Most\nprominent are pulsation variables like Miras (LPVs) and \δ Cep stars, but\nwe also find other types of variable stars, e.g. RV Tauri stars, irregular red\nvariables etc. We present a preliminary census for the three galaxies DDO 216,\nLeo A and GR8.\n
