“…However, it was reported that sodium values increase the number of Cyanophyta as compared to Chlorophyta (Table 1, 2). The same result was obtained by Shubert and Starks (1980). On the other side a positive correlation of algal abundance (mainly Chlorophyta) during succession with levels of PO 4 -P was observed in the reclaimed desert.…”

Abstract:The algal communities of cultivated land, reclaimed desert and waste land in relation to physico-chemical characters were followed during the study period (1996)(1997). Organic carbon, ammonia-N and Phosphate levels of soil samples are the major controlling factors affecting algal growth and distribution of algae in these sites. Also, the diversity of algal species was strongly affected by vegetation seasons. The decrease number of algae in the waste land compared to other soil samples may be due to high salinity of this soil. A positive correlation of algal abundance and diversity (mainly diatoms and green algae) during succession with levels of PO 4 -P was observed in reclaimed desert. Blue-green algae were more dominant in the cultivated soil and waste soil than in reclaimed desert.

“…Species diversity of algae, of both the Cottbus and Sokolov areas, was usually much higher than in other post‐mining areas, regardless of whether the sites were revegetated, ameliorated, or left to spontaneous succession (Shubert & Starks 1979, 1980; Starks & Shubert 1979,1982; Lukešová & Komárek 1987; Maxwell 1991). Species, especially the most frequent ones, found in both areas are common soil species with broad ecological amplitude.…”

“…In North Dakota, Shubert and Starks (1979) studied algal succession on naturally revegetated mine spoil banks; Starks and Shubert (1979) examined the soil algae of revegetated plots, which had been treated with a variety of amendments. The same researchers (Shubert & Starks 1980) evaluated the relationships of algae to the soil environments, studying algae together with soil chemical and physical properties in surface mined soils in semiarid and arid areas in Arizona, New Mexico, and North Dakota. Shushueva (1985) investigated algal succession in coal mining areas in Kuzbas.…”

Algal communities were investigated in two contrasting chronosequences established on reclaimed spoils in the west Bohemian brown coal mining district near Sokolov (Czech Republic) and in the Lusatian lignite mining district near Cottbus (Germany). The Sokolov chronosequence was characterized by tertiary cypric clay substrate, afforestation with Alnus glutinosa (L.) Gaertn., and high pH of deposited spoil material, Cottbus chronosequence by tertiary carboniferous and pyritic sand of extremely low pH ameliorated by fly ash, and afforestation with Pinus sylvestris L. and P. nigra Arnold. A total of 122 species of algae was found in both areas. Although the same species number (80) was identified from Sokolov and Cottbus, both proportion of individual algal groups and species composition were different. Green algae prevailed in both areas, but in Sokolov cyanobacteria and diatoms were also quite diverse, and in younger sites they were also abundant. Total abundance of algae ranged mostly between 10 4 -10 7 cells/g dry soil, and was one order higher in Cottbus than in Sokolov. Species number was high in young sites, decreased with increasing age, and was the lowest in control forests. In Sokolov, the highest abundance was recorded in the youngest alder plantation. In Cottbus, sludge and compost fertilization used in the youngest pine plantations resulted in rapid formation of visible algal crusts dominated by Klebsormidium crenulatum (Kütz) Lokhorst. š

“…Some taxa of green algae identified in the present study have been reported from salt-affected soils. This includes taxa such as the filamentous Dilabifilum/Pseudendoclonium-like algae (Vinogradova and Darienko, 2008), Tetracystis (Kirkwood and Henley, 2006;Vinogradova and Darienko, 2008), Chlorella (Shubert and Starks, 1980;Vinogradova and Darienko, 2008) and Borodin ellipsis as well as Diplosphaera chodatii, Chloroidium ellipsoideum and Stichococcus bacillaris (Vinogradova and Darienko, 2008). Some of these algae are known to produce osmotically active substances such as sucrose (Chlorella vulgaris, Chloroidium ellipsoideum), ribitol (Chloroidium ellipsoideum) and sorbitol (Stichococcus sp.…”

Halophilic Algal Communities in Biological Soil Crusts Isolated From Potash Tailings Pile Areas

Mining potash for fertilizer produces vast amounts of highly saline waste that is deposited in potash tailings piles. Rainfall washes the salts out, affecting the surrounding ecosystems. Only salt-tolerant organisms occur close to the piles, since other species cannot survive in these hypersaline conditions. Halophytic plant communities around tailings piles have been well investigated. However, studies exploring the biodiversity of the space behind the vegetation line that separates suitable salinities for plant growth from hostile conditions are rare. On top of the tailings piles, only microorganisms thrive. This study, for the first time, explored the microalgae and cyanobacteria in biocrusts that inhabit potash tailings pile areas between the vegetation line and the pile body. Two biocrust types were studied: young biocrusts at or close to the tailings piles, and established biocrusts situated in the near surroundings. The estimated abundance of green algae, cyanobacteria and diatoms was studied using a direct microscopy approach, followed by the isolation and establishment of unialgal strains and morphological species determinations. Soil environmental characteristics were analyzed. Soil samples showed EC Sat (electrical conductivity) values that drastically exceeded the scales commonly used to describe soil salinity, indicating extremely saline conditions. Indeed, the isolate composition was shaped by soil salinity parameters. Soil EC Sat of young biocrusts tended to be higher than in established biocrusts, and filamentous green algae were most abundant. In contrast, established biocrusts tended to have a lower EC Sat and were mostly dominated by filamentous cyanobacteria. Algal and cyanobacteria isolate composition differed significantly in young and established biocrusts, although the species number did not. Some of the salt-tolerant algal strains are assumed to be candidates for the formation of artificial biocrusts on the surface of the tailings. Attempts to "green" the piles by the establishment of higher plants to trap rainwater and therefore reduce the salt-output are difficult to apply. Plants require a thick layer of substrate to reduce the salinity, and the substrate easily erodes on the steep slopes. However, microalgae isolated from potash tailings pile areas seem promising, since they can survive on a thinner substrate layer and are already adapted to these hypersaline conditions.
