Frenzel, P., Keyser, D. & Viehberg, F.A. 2010: An illustrated key and (pala6e6o)ecological primer for Postglacial to Recent Ostracoda (Crustacea) of the Baltic Sea. Boreas, Vol. 39, pp. 567–575. 10.1111/j.1502-3885.2009.00135.x. ISSN 0300-9483

This synopsis of Baltic Sea brackish water Ostracoda gives an overview of all known Recent species for the first time. It also includes Holocene taxa now extinct in the area. There are 131 species, two of which are recorded only from Yoldia stage (Preboreal) sediments. The illustrated key is based exclusively on valve morphology, providing a taxonomical base for geoscience and biological studies using ostracods from the Baltic Sea area. A list of ecological tolerances and preferences as well as the latitudinal distribution of all species is intended as a reference for palaeoenvironmental analyses. Salinity, temperature and oxygen tolerance values as well as preferences for latitudinal distribution, water depth and energy, habitat and substrate are given. The data are based on quantitative sampling in the southern, central and western Baltic Sea and on information gained from literature.
