Unicellular green algae of the genus Interfilum (Klebsormidiales, Streptophyta) are typical components of biological soil crusts. Four different aeroterrestrial Interfilum strains that have previously been molecular-taxonomically characterized and isolated from temperate soils in Belgium, Czech Republic, New Zealand, and Ukraine were investigated. Photosynthetic performance was evaluated under different controlled abiotic conditions, including dehydration, as well as under a light and temperature gradient. For standardized desiccation experiments, a new methodological approach with silica gel filled polystyrol boxes and effective quantum yield measurements from the outside were successfully applied. All Interfilum isolates showed a decrease and inhibition of the effective quantum yield under this treatment, however with different kinetics. While the single cell strains exhibited relatively fast inhibition, the cell packet forming isolates dried slower. Most strains fully recovered effective quantum yield after rehydration. All Interfilum isolates exhibited optimum photosynthesis at low photon fluence rates, but with no indication of photoinhibition under high light conditions suggesting flexible acclimation mechanisms of the photosynthetic machinery. Photosynthesis under lower temperatures was generally more active than respiration, while the opposite was true for higher temperatures. The presented data provide an explanation for the regular occurrence of Interfilum species in soil habitats where environmental factors can be particularly harsh.

The distribution of polyols was examined for the first time in 34 green algal strains from four different clades belonging to the class Trebouxiophyceae, which dominate aeroterrestrial biofilms of many regions. Sorbitol was detected in representatives of the Prasiola clade, while ribitol was present in the Elliptochloris and Watanabea clades. Apatococcus lobatus (Chodat) J. B. Petersen contained erythritol in addition to ribitol. Polyols are considered as effective stress metabolites exerting multiple protective functions in metabolism and hence mainly occur in organisms colonizing extreme environments. In contrast, members of the Chlorella clade, which mainly occur in aquatic habitats, did not contain polyols. Thus, the constitutive presence of specific polyols facilitates a differentiation between species of the Prasiola clade from the Elliptochloris and Watanabea clades, respectively, and further allows differentiation of morphologically converging taxa.

“…Studies on subaerial algae growing in different habitats had been carried out since the 19th century [1][2][3][4][5]. Terrestrial microscopic green algae are the most widespread but the least known and most overlooked amongst all algal groups [6,7]. By and large, compared with that of fresh water and marine algae, the knowledge on diversity and distribution of algae and cyanobacteria in subaerial habitats is very scanty and lags far behind [8].…”

The study deals with a comparative study on diversity and species composition of subaerial algal communities from tree barks of closed undisturbed sacred grove, mixed plantation, and open disturbed forest. A total of 85 taxa had been recorded, 30 cyanobacteria and 55 algal species belonging to six classes of algae. Sacred grove harboured the highest subaerial algal diversity compared to those of plantation and open disturbed forest. There was a strong significant difference in species composition among the three different sampling areas. High number of diatoms with 14 species was recorded in sacred grove. Cyanobacteria with 22 species were the frequent group in disturbed forest whereas Trentepohliales dominated in plantation. Canonical correspondence analysis confirmed that high photon irradiance favored the growth of cyanobacteria in disturbed forest. The abundance of Trentepohliales members correlated to high rainfall and photon irradiance. High diversity and presence of many diatom species in undisturbed Mawphlang sacred grove were associated with low photon irradiance and high relative humidity and could also be due to a presence of suitable substrata formed by the growth of mosses. Sunlight, relative humidity, and rainfall were the important factors which played a major role in determining the diversity and distribution of subaerial algal communities.
