The silica-scaled chrysophytes of the elbe sandstone region, czech republic

Abstract

We investigated the silica-scaled chrysophyte flora (classes Chrysophyceae and Synurophyceae) in the Czech part of the unique Elbe sandstone region. We focused on such types of habitats that had not been studied in the region before - small ponds, forest pools and headwater streams. In 10 localities we found altogether 20 chrysophyte species. Chrysodydimus synuroideus, Mallomonas multisetigera and M. striata var. serrata were recorded from the Czech Republic for the first time. Moreover, another 4 species were first records for the Elbe sandstone region. Living chrysophytes were also observed in sediment samples, though they are generally believed to be planktonic. © Czech Phycological Society.
