The polyphasic approach has been widely applied in cyanobacterial taxonomy, which frequently led to additions to the species inventory. Increasing our knowledge about species and the habitats they were isolated from enables new insights into the ecology of newly established genera and species allowing speculations about the ecological niche of taxa. Here, we are describing three new species belonging to three genera that broadens the ecological amplitude and the geographical range of each of the three genera. Cyanocohniella crotaloides sp. nov. is described from sandy beach mats of the temperate island Schiermonnikoog, Netherlands, Oculatella crustae‐formantes sp. nov. was isolated from biological soil crusts of the Arctic Spitsbergen, Norway, and Aliterella chasmolithica originated from granitic stones of the arid Atacama Desert, Chile. All three species could be separated from related species using molecular sequencing of the 16S rRNA gene and 16S–23S ITS gene region, the resulting secondary structures as well as p‐distance analyses of the 16S–23S ITS and various microscopic techniques. The novel taxa described in this study contribute to a better understanding of the diversity of the genera Cyanocohniella, Oculatella, and Aliterella in different habitats.

移动边界:基于蓝藻属 Cyanocohniella、Oculatella 和 Aliterella 的三个新物种的生态和地理范围扩展。

多相方法已广泛应用于蓝藻分类学,这经常导致物种清单的增加。增加我们对物种及其被隔离的栖息地的了解,可以对新建立的属和物种的生态学产生新的见解,从而可以推测分类群的生态位。在这里,我们描述了属于三个属的三个新物种,它们扩大了三个属的生态幅度和地理范围。Cyanocohniella crotaloides sp。十一月 描述于荷兰温带岛屿 Schiermonnikoog 的沙滩垫上,Oculatella crawlae-formantes sp。十一月 分离自北极斯匹次卑尔根、挪威和Aliterella chasmolithica的生物土壤结皮起源于智利干旱的阿塔卡马沙漠的花岗岩。使用 16S rRNA 基因和 16S-23S ITS 基因区域的分子测序、由此产生的二级结构以及 16S-23S ITS 的 p 距离分析和各种显微技术,可以将所有三个物种与相关物种分开。本研究中描述的新分类群有助于更好地了解不同栖息地的CyanocohniellaOculatellaAliterella属的多样性。
