Concentrations of particulate and dissolved cylindrospermopsin in 21 Aphanizomenon-dominated temperate lakes.
The cyanobacterial toxin cylindrospermopsin (CYN) is widely distributed in German lakes, but volumetric data for risk assessment are lacking and it is unclear which cyanobacterial species produce CYNExpand

Competitiveness of invasive and native cyanobacteria from temperate freshwaters under various light and temperature conditions
Some tropical cyanobacteria have spread to temperate freshwaters during the last decades. To evaluate their further development in temperate lakes, we studied the temperature- and light-dependentExpand

Microcystins (hepatotoxic heptapeptides) in german fresh water bodies
In 1995 and 1996 a total of 55 German water bodies with different trophic states were investigated for the presence of potentially microcystin‐producing cyanobacteria. The seston biomass of over 500Expand

Distribution of three alien cyanobacterial species (Nostocales) in northeast Germany: Cylindrospermopsis raciborskii, Anabaena bergii and Aphanizomenon aphanizomenoides
A. Stüken, J. Rücker, T. Endrulat, K. Preussel, M. Hemm, B. Nixdorf, U. Karsten and C. Wiedner. 2006. Distribution of three alien cyanobacterial species (Nostocales) in northeast Germany:Expand

Dynamics of planktonic food webs in three mining lakes across a pH gradient (pH 2–4)
Acidic mining lakes (ML) in Lusatia (Germany) are characterised by their geogenically determined chemistry. The present study describes the structure, main components and relationships within theExpand

Climate change affects timing and size of populations of an invasive cyanobacterium in temperate regions
Cylindrospermopsis raciborskii, an invasive freshwater cyanobacterium, originated from the tropics but has spread to temperate zones over the last few decades. Its northernmost populations in EuropeExpand

Occurrence of the cyanobacterial toxin cylindrospermopsin in northeast Germany
The frequent occurrence of the cyanobacterial toxin cylindrospermopsin (CYN) in the (sub)tropics has been largely associated with cyanobacteria of the order Nostocales of tropical origin, inExpand

Chrysophytes and chlamydomonads: pioneer colonists in extremely acidic mining lakes (pH <3) in Lusatia (Germany)
Twenty-three extremely acidic (pH between 2.5 and 3.5) mining lakes in Lusatia (Germany) were analysed in order to classify their hydrochemistries and to assist the understanding of phytoplanktonExpand

Mining lakes in a disturbed landscape: Application of the EC Water Framework Directive and future management strategies
Some of the several hundred Lusatian mining lakes originating from lignite mining will be among the largest and deepest lakes in Germany. A special problem of many of these lakes is severeExpand
