Cyanobacteria were sampled along two vertical and two horizontal transects in the littoral of Devoke Water, English Lake District. Profiles of cyanobacterium diversity and abundance showed that both attained a maximum close to the water line, but declined rapidly 20-40 cm above it. The distribution of individual species with height together with species and site ordinations showed that several taxa occurred in well-defined zones. A narrow "black zone" in the supralittoral was colonised mainly by species of Calothrix, Dichothrix and Gloeocapsa with pigmented sheaths. There was no evidence of lateral variation of species around the lake, but the height of the black zone correlated positively with wind exposure. The flora of Devoke Water is that of a base-poor mountain lake with some elements of a lowland, more alkaline water-body.
沿德文特湖的浅滩，沿着两条垂直和两条水平的横截面对蓝藻进行了采样。蓝藻多样性和丰度的分布情况表明，两者在接近水位线的地方达到最大值，但在水位线以上 20-40 厘米的地方迅速下降。随着物种和地点的排列，个体物种的分布与高度一起表明，有几个分类单元出现在定义明确的区域。在超潮带的一个狭窄的“黑色区域”主要由具色素鞘的Calothrix、Dichothrix 和 Gloeocapsa 物种所占据。湖周围没有物种侧向变化的证据，但黑色区域的高度与风暴露呈正相关。德文特湖的植物群是贫碱的高山湖泊，具有一些低地、碱性更强水体的特征。
