“…In the current study, the several minority species isolated by Durrell from generously inoculated sterile sand supports the greater effectiveness postulated for original natural media in experimental cultures (Parker and Bold, 1961). Many cause-effect relationships remain to be established between the floristic composition of soil-algal populations and possible determinative microand macro-environmental variables (Prescott, 1956). The total nitrogen content of nitrogen-fixing algae is much greater than in higher plants, amounting to 7-8% on a dry-weight basis (Fogg, 1947).…”

Shields, Lora Mangum, and Francis Drouet. (New Mexico Highlands U., Las Vegas.) Distribution of terrestrial algae within the Nevada Test Site. Amer. Jour. Bot. 49(6): 547–554. Illus. 1962.—Twelve terrestrial algal species, other than diatoms, were identified by microscopic examination of natural soil growths from the Nevada Test Site. Four soil species appeared in culture only. Fifteen taxa occurred only in the vicinity of the one aquatic habitat. Colloidal sheaths of Microcoleus vaginatus, Schizothrix californica and Schizothrix aculissima stabilize soil particles, forming a surface crust. Nostoc commune, Scytonema hofmannii and Protosiphon cinnamomeus are commonly associated with lichens. With one exception, no natural algal growths were found within 0.6 mile of nuclear detonation points during the 2 years following an event. Since at least one species, Microcoleus vaginatus, survives acute gamma exposures of 2,560 kr, blast and thermal damage, rather than radiation, appear to account for the removal of soil algae. The slow recovery can be explained largely in terms of aridity. Soil texture, which influences cohesiveness and moisture levels, strongly affects the composition of terrestrial algal populations in relation to major shrub types within the test site.

“…These inventories were organized using the concept of a `community' or `association' of species (e.g. Fritsch, 1929; Fritsch & Pantin, 1946; Blum, 1956; Prescott, 1956; Symoens, 1951, 1957; Golubic, 1967; Kann, 1978; Stock & Ward, 1991; Guach & Sabater, 1995). In addition to these inventories, communities have been described in relationship to the time of the year and the environment, e.g.…”

In freshwater environments such as river and stream bottoms, rocks and submerged vegetation are covered with a biological felt (also called a periphyton, microbial mat, biofilm, etc.) that is susceptible to calcification. Compilation of an extensive bibliography and our own observations have allowed the identification of 44 species of Coccogonophyceae, 122 Hormogonophyceae, 2 Chrysophyceae, 35 Chlorophyceae, 3 Xanthophyceae, 2 diatoms, and 3 Rhodophyceae that grow on calcareous tufa and coat vegetation. Diverse genera include species that are also calcified but impossible to determine because they lack reproductive organs. Crystals have been described from 74 species in the literature and we have observed 53 others. They can be classified into 10 groups: (1) platelets on cell walls (Volvocales, analogues of coccolithophorids) (2) crystals in mucilage (Synechococcus, diatoms, Hydrurus) and calcified stalks (Oocardium) (3) sheaths containing crystals in the form of simple or three‐branched needles, dendritic crystals, and crystals with box‐work fabric (Geitleria, Scytonema) (4) sheaths containing calcite spherulites (5) stalks intersecting a large crystal (Cymbella) (6) micrite tubes (Phormidium, Schizothrix) (7) isolated rhombohedra (Zygnema, Scytonema), rhombohedra in clusters or chains (Nostoc parmelioides) (8) sparite platelets (Vaucheria) or isodiametric crystals (Scytonema, Chaetophora) (9) large crystals crosscut by many parallel filaments (Rivularia, Batrachospermum), and (10) fan‐like crystals (Phormidium). These crystals can be arranged in clusters or form regular laminations. They can transform into isodiametric sparite crystals to form fan‐like or radial palisadic structures. Knowledge of primary crystals and their diagenetic transformations is necessary to correctly interpret freshwater stromatolites. The latter always result from intense calcification and are a diagenetic transformation of a biological felt made of many prokaryotic and eukaryotic algal species, small invertebrates, and organic and mineral debris.

“…Smith, 1950, has an excellent discussion of haploid-diploid variability in the algae. Soil-rooted aquatic plants, characteristically diploid (sporophyte) organisms generally having an excellent mineral-conducting system, extract iron and other mineral salts directly from the water-immersed soil medium; thus, they live aerobically in anaerobic growth situations (Crafts, 1954;Lowenhaupt, 1955;Marei, 1955;Pond, 1903;Prescott, 1956). Normally free-floating aquatic plants, whether haploid.…”
