“…Many macrophyte species also excrete allelopathic substances which can inhibit cyanobacterial growth (Gross 2003;Hilt and Gross 2008). Cyanobacteria species and strains, however, may show a differential sensitivity towards macrophyte allelochemicals (Eigemann et al 2013;Š vanys et al 2014), but existing studies on the sensitivity of toxic versus non-toxic strains of cyanobacteria were contradictory (Mulderij et al 2005;Liu et al 2007;Š vanys et al 2014). In addition, most studies on macrophyte allelopathic effects have been conducted with single cyanobacteria species, and species interactions may reverse the results (Chang et al 2012).…”

Climate change can promote harmful cyanobacteria blooms in eutrophic waters through increased droughts or flooding. In this paper, we explore how water-level fluctuations affect the occurrence of cyanobacterial blooms, and based on the observations from case studies, we discuss the options and pitfalls to use water-level fluctuations for lake and reservoir management. A drawdown in summer causes an increase in retention time and increased water column nutrient concentrations and temperature of shallow water layers, which may lead to severe cyanobacterial blooms. This effect can potentially be counteracted by the positive response of submerged macrophytes, which compete for nutrients with cyanobacteria, with a higher chance of cyanobacterial blooms under eutrophic conditions. The balance between dominance by submerged macrophytes or cyanobacteria is temperature sensitive with stronger positive effects of drawdown as inhibition of cyanobacterial blooms expected in colder climates. Complete drying out reduces the amount of cyanobacteria in the water column after refilling, with lower water nutrient concentrations, lower fish biomass, lower abundance of cyanobacteria, higher transparency, and higher cover of submerged plants compared to lakes and reservoirs that did not dry out. Water-level rise as response to flooding has contrasting effects on the abundance of cyanobacteria depending on water quality. We conclude that waterlevel fluctuation management has potential to mitigate cyanobacterial blooms. However, the success will depend strongly on ecosystem properties, including morphometry, sediment type, water retention time, quality of inlet water, presence of submerged vegetation or propagules, abundance of fish, and climate.

“…And this was initiated only under conditions of severe DNA damage. Liu et al (2007) showed that cell density of toxic M. aeruginosa was only reduced 1.6% after a 2-d exposure to pyrogallol at a concentration of 4.5 mg L À1 in BG 11 medium, thus reflecting that M. aeruginosa was not severely damaged in concentrations less than 4.5 mg L…”

“…Previous studies indicated that these two M. aeruginosa types exhibited differences in competition ability (Kardinaal et al, 2007) as well as the responses to environmental stresses. Non-toxic M. aeruginosa was more susceptive to pyrogallol stress than toxic M. aeruginosa (Liu et al, 2007); however, the toxic strain was more sensitive than non-toxic one to the allelopathic effect from Stratiotes aloides (Mulderij et al, 2005). As for these thirteen M. aeruginosa strains examined in this study, it includes seven microcystins producing strains and six non-microcystins producing strains (Fig.…”

“…Microcystis strains, with two types of cellular phenotype as single cell and colonial form, usually co-exist in natural waters (Kessel and Eloff, 1975;Reynolds et al, 1981). Recently, some studies reported that intrinsic characteristics and phenotypes of algae could affect the responses of algae to environmental stress (Liu et al, 2007;Wu et al, 2007).…”
