Abstract:
... Cyanobacterial toxins have been regarded by some researchers as allelopathic substances that could modulate the growth of competitors. Nevertheless, often the concentrations of toxins used are too high to be considered ecologically relevant. In this work we tested the hypothesis that microcystin-LR (MC-LR) and cylindrospermopsin (CYN) at ecologically relevant concentrations have no allelopathic ef ...

Abstract:
... Microcystis aeruginosa and Microcystis wesenbergii are two cyanobacteria commonly found in eutrophic shallow lakes. Previous studies reported that microcystin-producing M. aeruginosa could have an increased competitive potential on other algae and aquatic plants, and microcystin-LR (MC-LR) was regarded as an allelochemical. Based on this hypothesis, the allelopathic interaction between these two c ...

Abstract:
... Zooplankton may at times graze cyanobacteria. However, their top-down effects are considered to be low, particularly in tropical regions dominated by small-size grazers that may be unable to consume efficiently filamentous or colonial species. Recently, cyanobacteria blooms were reported in the Senegal River hydrosystem. We conducted feeding experiments to assess the ability of copepods (Pseudodia ...

Abstract:
... Phosphorus release from Microcystis aeruginosa and attached bacterium (Pseudomonas sp.) isolated from Lake Taihu was examined using a phosphorus isotope tracer in order to investigate the phosphorus transference between the two species. Our results reveal that the amount of phosphorus released form ³²P-saturated M. aeruginosa is determined by its growth phase and most of phosphorus is assimilated ...

Abstract:
... Eichhornia crassipes is an invasive, floating macrophyte and may have biocontrol functions on harmful cyanobacteria blooms. Eichhornia produces N-phenyl-2-naphthylamine (PNA), a compound which can inhibit algae. However, the impact of PNA on allelopathic effects of the cyanobacterium Microcystis aeruginosa on other phytoplankton species is not clear. In this study, we tested whether PNA can influe ...

Precipitation is the major source of water for this closed basin lake. In addition, ground water is used for replenishing the lake regularly. This alkaline, hyposaline hard water lake contains very high ionic concentrati ...

Abstract:
... Although the cyanobacterium Microcystis is colonial during water blooms, isolated Microcystis strains become unicellular in culture. Studies indicate that heterotrophic bacteria can promote Microcystis colonies in culture, but little is known about the underlying mechanism or how widespread it is among bacteria. This study investigated the identity and colony-promoting effects of bacteria isolated ...

... Invasion of freshwaters by non-native animal species is a major threat to global aquatic systems. Asian clams (Corbicula fluminea) and quagga mussels (Dreissena rostriformis bugensis) are two highly invasive bivalves in North America that share life histories that facilitate invasion; however, they may experience different stress tolerances which can influence local population distribution. We com ...

In this study, the fates of intra- and extracellular microcystin-LR (MC-LR) were investigated when the mixotrophic golden alga Poterioochromonas sp. (ZX1) was grazing on M. aeruginosa cells. In the control groups, the total MC-LR concentration increa ...

Abstract:
... The increasing occurrence of cyanobacterial blooms in freshwaters is of great concern due to the ability of many cyanobacteria to produce cyanotoxins. In the present work, the eutrophied Vela Lake (Central Portugal), used for recreational purposes and as a water source for agriculture, was monitored every fortnight between 2000 and 2001. Phytoplankton diversity and densities were measured and corr ...

Abstract:
... The most frequently observed cyanotoxins are microcystins. They trigger a cascade of events leading to cellular responses. The hypothesis of the study was that cyanobacteria affect ciliates as solitary species and as assemblages. The aim of our study was to determine whether ciliates respond to cyanobacteria because of the presence of cyanotoxins (microcystins—MC). We set up experiments with toxic ...
