Abstract

The paper presents results of detailed phytoplankton investigations in Lake Stechlin between 1994 and 2003. The analysis includes the picoplankton fraction (dominated by Cyanobium sp.) that regularly appears as a deep-layer chlorophyll maximum (DCM). Planktothrix and Aulacoseira are successful competitors against Cyanobium in the isothermal period, the consequences differ markedly due to the fact that Planktothrix is able and Aulacoseira is unable to accumulate in the DCM after the onset of thermocline. The „regular-Cyanobium” and „irregular-Planktothrix, -Aulacoseira” patterns of DCM development has a basic influence on ecosystem functioning. Lake Stechlin a pristine, oligo-mesotrophic deep lake, with an established and detailed monitoring system and thus has been an ideal reference site for studying the influence of global climate changes on plankton that may improve our predictive tools for impact assessment.
