In this paper we analyzed how well the akinete bank in the sediments from a shallow lake reflected past blooms of planktonic Nostocales (cyanobacteria), the akinete bank’s potential for reflecting future blooms and whether different nutrient scenarios affect germination and recruitment using a laboratory experiment. Most species found in the plankton were also found in the akinete bank and in the germination experiment. Based on their shape, the most abundant viable akinetes in the sediments potentially corresponded to some of the species forming intense blooms in previous years, and coincided with the most abundant species in a 3-week germination experiment. The effects of nutrients on germination and recruitment were only observed in the early phase of the life cycle (Day 7), where nitrogen-sufficient conditions enhanced germination, while phosphorus concentration had a positive effect on the number of heterocytes. Combined approaches of morphological analysis and experimental germination seem a good method for assessing the past diversity of Nostocales and allowing predictions of the diversity of potential future blooms in shallow lakes and as a tool for water quality management, especially in water bodies lacking information on previous cyanobacteria blooms.

沉积物秋葵银行将浅水湖泊中的诺萨卡斯山脉的过去和未来的花朵联系起来

在本文中，我们通过实验室实验分析了浅湖沉积物中的秋葵银行如何很好地反映了浮游性Nostocales（蓝藻）的过去开花，秋葵银行反映未来绽放的潜力以及不同的养分状况是否影响发芽和吸收。在浮游生物中发现的大多数物种也都在akinete河岸和发芽实验中发现。根据它们的形状，沉积物中最丰富的有生命的akinets可能对应于一些在前几年形成强烈水华的物种，并且在3周的发芽实验中与最丰富的物种相吻合。营养素仅在生命周期的早期阶段（第7天）观察到养分对发芽和补充的影响，在此阶段，氮充足的条件会增强发芽，磷的浓度对杂细胞数有积极影响。形态分析和实验发芽相结合的方法似乎是一种评估过去念珠菌多样性并预测浅水湖泊未来潜在水华多样性的好方法，并且可以作为水质管理的工具，尤其是在缺乏先前蓝细菌信息的水体中绽放。
