持续不断的全球变暖和富营养化预计将在全球范围内促进蓝藻的优势地位。尽管湖泊温度和营养物质的增加是水华爆发的公认驱动因素，但决定蓝藻生物量的机制是复杂的，具有潜在的直接、间接和相互作用的影响。蓝藻可以产生毒素，对动物和人类的健康构成相当大的风险，因此，如果我们要确保安全的饮用水，就会付出巨大的经济代价。这样的全球范围现象应该在广泛的空间尺度上进行研究，以便直接比较不同类型湖泊中不同气候带的浮游植物反应。欧洲多湖调查(EMLS)试图利用群体科学的力量，对欧洲各地的湖泊进行采样，并弄清环境应激源对潜在有毒蓝藻水华的影响。第一个EMLS结果表明，蓝藻毒素在湖泊中的分布和毒性潜力将高度依赖于温度的直接和间接影响。如果营养物质不受调控，那么它们可能会与湖温上升协同作用，比其他浮游植物更能促进蓝藻的生长。提供大陆尺度的证据对于开发能够预测蓝藻或藻类对环境变化的反应的可靠模型具有非常重要的意义。
On‐going global warming and eutrophication are expected to promote cyanobacterial dominance worldwide. Although increased lake temperature and nutrients are well‐established drivers of blooms, the mechanisms that determine cyanobacterial biomass are complex, with potentially direct, indirect, and interactive effects. Cyanobacteria can produce toxins that constitute a considerable risk for animal and human health and thus a substantial economic cost if we are to ensure safe drinking water. Such global range phenomena should be studied at a wide spatial scale, to directly compare phytoplankton response in different lake types across contrasting climatic zones. The European Multi Lake Survey (EMLS) sought to harness the power of group science in order to sample lakes across Europe and disentangle the effect of environmental stressors on potentially toxic cyanobacterial blooms. The first EMLS results showed that the distribution of cyanobacterial toxins and the toxic potential in lakes will be highly dependent on direct and indirect effects of temperature. If nutrients are not regulated, then they may interact synergistically with increased lake temperatures to promote cyanobacterial growth more than that of other phytoplankton taxa. Providing continental scale evidence is highly significant for the development of robust models that could predict cyanobacterial or algal response to environmental change.
