Small-scale variation of corticolous microalgal covers: Effects of microhabitat, season, and space

Original language description

The present study focuses on temporal and microscale spatial variation of the community structure and richness of subaerial microalgae growing on the bark of European beech (Fagus sylvatica) trees in temperate deciduous forests. Subaerial phototrophic biofilms present common and conspicuous microalgal communities growing on a variety of natural and man-made substrata. However, in comparison with other major microalgal communities such as phytoplankton and microphytobenthos, basic patterns of their spatio-temporal variation remain largely unknown. The bark samples were collected six times each spring and autumn in a period of 3years (2010-2013) and were cultured on agar plates, and then individual clonal strains were identified by light microscopy. A total of 55 morphotypes (considered as operational taxonomic units for subsequent analyses) were recognized, which mainly belong to the classes Trebouxiophyceae and Chlorophyceae. Interestingly, temporal variation explained the largest proportion of variation in the community structure. This variation was primarily related to seasonal fluctuations, and although the communities recorded in spring and autumn showed many overlapping taxa, a clear distinction in species composition and abundance was observed. However, the microhabitat characteristics such as bark roughness also significantly structured the microalgal community. Conversely, spatial factors such as the height of the samples above ground or distance of the samples on a trunk seemed to be of lesser importance on this scale. Thus, we concluded that the previously unrecognized seasonal changes, resulting from variation in temperature, humidity, and irradiance, as well as the non-seasonal temporal changes, possibly resulting from local colonization or extinction of individual taxa, should be considered as one of the important factors in structuring aerial microalgal communities.
