TY - JOUR A1 - Jersabek, Christian D. A1 - Weithoff, Guntram A1 - Weisse, Thomas T1 - Cephalodella acidophila n. sp (Monogononta: Notommatidae), a new rotifer species from highly acidic mining lakes JF - Zootaxa : an international journal of zootaxonomy ; a rapid international journal for animal taxonomists N2 - We describe a new species of Cephalodella, C. acidophila n. sp., from the plankton of two extremely acidic mining lakes (pH <3) in Austria and Germany. The species is morphologically closely related to Cephalodella delicata Wulfert. It shares with the latter an almost identical trophi morphology and anatomical organization, but differs clearly by form and length of its toes, larger body size, and ecology. Laboratory experiments revealed that the species is acidophilic, i.e. it thrives at low pH (<4) and does not survive at circumneutral conditions. The species occurs in man-made habitats at low to moderate abundance (usually 5-22 individuals l(-1)) and in stock cultures thrives on the green alga Chlamydomonas acidophila. The easily cultured species has previously been used in various experimental studies, but has only now been recognized as an undescribed species.
