“…Outer bark and the bark surface are more greatly impacted by the effect of pollutants and leaching than more interior bark. Over time, this can cause the bark surface to irreversibly lose its buffering capacity and produce lower pH values (Farmer et al 1990;Kuang et al 2006). The strength of the regression fit of increasing pH with height above the ground (Table 2a) supports this.…”

“…The studies cited above all mixed or soaked pulverized or pieces of bark in distilled water for 12-24 hours before determining pH from the bark or solution in a laboratory setting. Secondly, a study of Pinus massoniana has shown that pH of outer bark was significantly lower than that of inner bark (Kuang et al 2006). Outer bark and the bark surface are more greatly impacted by the effect of pollutants and leaching than more interior bark.…”

“…In addition to higher water availability, bark fissures probably also differ from the smooth surface in their physico‐chemical conditions, related to different tree tissues exposed to the microalgal growth (Whitmore ). Fritz et al () showed, that in the case of beech trees, pH values of outer and inner bark portions does not differ (in contrast to conifers, where the fissures have significantly higher pH values than smooth portions of bark, Legrand et al ; Satake et al ; Kuang et al ). Still, the rough microhabitats possess unique characteristics – bark fissures are considerably shadier, retains snow and dust and are more sheltered against wind (Barkman ).…”

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 3 years (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.

“…To establish an active population at a particular site, successful dispersal of viable algae is important. The dispersal of algae is through passive means such as by water, air, and other organisms, including humans [3]. Algae not only inhabit marine and freshwater ecosystem but they also occur in a wide variety of terrestrial environments [4].…”
