While the occurrence of these algae in this habitat has long been recognised there have been few detailed studies of the composition and distribution of the organisms responsible since the work of Godward on Windermere in the English Lake District [ 1 ]. Further afield, more recent studies have indicated that cyanobacteria colonising this habitat are often related to the water level, suggesting a relationship with the frequency of wetting and drying events and tolerance to desiccation. Since water absorbs the solar radiation there is a negative correlation between water depth and this variable.
At, or above water level, both visible and ultraviolet radiation may be intense, particularly at high altitudes and several studies have addressed this issue in the lake littoral [ 2 , 3 ]. There is also evidence to suggest the chemical composition of the water [ 4 ], the nature of the substratum [ 5 ] and the prevailing climate [ 6 ] influence the flora.

This paper provides information on the littoral cyanobacterium flora of Devoke Water, a small rocky lake in the English Lake District. This lake was selected for its extensive rocky shores and exposed position. With prevailing westerly winds, the eastern shore of the lake is most exposed to wave action providing a range of exposures on the different shores.
The aims of the investigation are three-fold; to examine the cyanobacterium flora and compare it with the littoral of other Cumbrian and continental lakes; investigate zonation patterns species associations and diversity above and below the water line and finally to determine the effect of exposure on the distribution and abundance of the cyanobacteria. The morphometry, palaeolimnology and general biology of this lake has been previously investigated and a range of limnological data are provided in Table 1.
The catchment bedrock consists of granite and andesitic volcanic rocks overlain by glacial till and thin acidic peat soils [ 7 ]. Precipitation at this location is high, approximately mm per annum and is distributed throughout the year with small maxima in winter and late summer. Mean air temperature is close to 8.
