Competitiveness of invasive and native cyanobacteria from temperate freshwaters under various light and temperature conditions
TLDR
Any further temperature increase would promote the growth and development of Nostocales species in general, and that of the invasive species in particular, and would enable a more northward expansion of A. ovalisporum.
Microcystins (hepatotoxic heptapeptides) in german fresh water bodies
TLDR
The seasonal levels of these cyanobacteria were clearly reflected by microcystin concentrations in the water bodies, which varied by 4 orders of magnitude at bathing sites in 1997 during a mass development of Microcystis spp.
Distribution of three alien cyanobacterial species (Nostocales) in northeast Germany: Cylindrospermopsis raciborskii, Anabaena bergii and Aphanizomenon aphanizomenoides
TLDR
Investigating the spatial distribution and relative frequency of C. raciborskii close to its northernmost distribution limit and the habitat in which it is most likely to occur in this climatic zone concluded that alien thermophilic cyanobacterial species are much more widely distributed in temperate Germany than previously known.
Climate change affects timing and size of populations of an invasive cyanobacterium in temperate regions
TLDR
It is concluded that an earlier rise in water temperature associated with climate change has promoted the spread of C. raciborskii to the temperate zone, thereby shifting the pelagic populations to a phase with higher Imix, which advances growth and the population establishment.
Dynamics of planktonic food webs in three mining lakes across a pH gradient (pH 2–4)
TLDR
The structure, main components and relationships within the food webs of three acidic mining lakes with different pH values (ML 111; ML 117; ML Felix: pH 2.8) are described in order to show their typical characteristics.
Occurrence of the cyanobacterial toxin cylindrospermopsin in northeast Germany
TLDR
It is suggested that CYN may be an important cyanobacterial toxin in German water bodies and that further data are needed to assess this, and analyses of phytoplankton data suggest Aphanizomenon sp.
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 phytoplankton
