New chrysophycean cyst morphotypes and their ecology in Finland

Research output: Contribution to journalArticleScientificpeer-review

Abstract

Despite multiple studies on chrysophyte stomatocysts globally, detailed surveys of these resting stages have remained scarce in Northern Europe. This is the first description of new chrysophyte cyst morphotypes in concordance with the International Statospore Working Group guidelines, based on scanning electron microscope images from lake sediment material in Finland. A nationwide chrysophyte cyst survey revealed 18 new cyst morphotypes with different surface ornamentation types. Environmental background information on the locations and the quantitatively calculated optimums and tolerances for electric conductivity, pH, total phosphorus and ice-free period are also provided.
