Geothermal diatoms: a comparative study of floras in hot spring systems of Iceland, New Zealand, and Kenya

Diatom floras were examined from geothermal environments in three contrasting tectonic settings. These included subduction-related acid and alkaline springs in New Zealand; alkaline springs along a divergent plate boundary on Iceland; and alkaline springs in the Kenya Rift. These shallow (\1 cm) aquatic environments vary considerably (e.g., temperature: 21.3-99°C; pH: 2.1-9.65; 56.41-643 mg l -1 SiO 2 ). Diatoms form an important component of geothermal floras at temperatures of\45°C. The floras from New Zealand are distinguished by the common occurrence of Pinnularia. Icelandic springs have a variety of Fragilariaceae. Navicula and Anomoeoneis are most common in the Kenyan springs. Statistical analyses suggest that the diatoms cluster into seven major groups. The most common taxa include: Achnanthidium exiguum v. heterovalvum (Kras.) Czarn., Anomoeoneis sphaerophora (Ehrenb.) Pfitz, Brachysira brebissonii f. thermalis Grun., Caloneis bacillum (Grun.) Cl., Craticula cuspidata (Kütz.) Mann, Diadesmis confervacea Kütz., Epithemia argus (Ehrenb.) Kütz., Frustulia rhomboides (Ehrenb.) DeT., Hantzschia amphioxys (Ehrenb.) Grun., Navicula tenelloides Hust., Nitzschia amphibia Grun., Nitzschia inconspicua Grun., Nitzschia invisitata Hust., Nitzschia frustulum (Kütz.) Grun., Nitzschia sigma (Kütz.) W, Smith., Pinnularia chapmaniana Fog., Pinnularia appendiculata (Ag.) Cl., Pinnularia molaris (Grun.) Cl., Pinnularia acoricola Hust., Rhopalodia gibberula (Ehrenb.) O. Müll., Staurosira construens v. venter (Ehrenb.) Ham., Staurosira elliptica (Schum.) Will. & Round, and Staurosirella pinnata (Ehrenb.) Will. &Round. Canonical correspondence analysis shows clear correlations between species, alkalinity, pH, and conductivity, with less strong correlations for silica and temperature. Other factors include substrate type, current velocity, and light conditions. The preservation potential of host deposits varies considerably, being lowest for springs on clastic deltas and highest where travertine or sinter is accumulating.

“…Further, diatoms are very sensitive to a variety of environmental conditions and can provide important information on the ecological integrity of these ecosystems (Niyatbekov & Barinova, 2018). In Europe, investigations on diatom flora in thermo-mineral springs have been carried out in the Czech Republic (Bílý, 1934; Lederer et al, 1998; Kaštovský & Komárek, 2001), France (Beauger et al, 2015; Beauger et al, 2016; Beauger et al, 2017), Iceland (Schwabe, 1933; Schwabe, 1936; Krasske, 1938; Van der Werff, 1941; Biebl & Kusel-Fetzmann, 1966; Owen, Renaut & Jones, 2008), Italy (Dell’Uomo, 1986; Mannino, 2007; Lai et al, 2019), the Republic of Macedonia (Stavreva-Veselinovska & Todorovska, 2010), Slovakia (Hindák & Hindáková, 2006; Hindák & Hindáková, 2007), and Spain (Leira, Meijide-Failde & Torres, 2017). Overall, these studies were limited and focused on individual or multiple springs in specific geological settings and the comparison between different geographic areas is rare (e.g., Petersen, 1946; Owen, Renaut & Jones, 2008).…”

This study investigated and compared the diatom flora from thermo-mineral springs in Auvergne (France) and Sardinia (Italy). Samples were collected from rock/cobbles and fine sediments in 16 springs between January 2015 and March 2017. A total of 207 taxa (59 genera) were found. Multivariate analyses revealed significant differences in species composition and abundance among diatom assemblages both within each geographic region and between Auvergne and Sardinia (global R = 0.516; p = 0.002), suggesting the importance of local and climatic factors in species distribution. Based on abundance and common occurrence in multiple sites, some taxa can be considered more representative of springs in each region: Crenotia thermalis for Auvergne and Lemnicola exigua, Nitzschia amphibia, N. inconspicua and Rhopalodia operculata for Sardinia. pH, conductivity and HCO3− were the most significant environmental variables for diatom assemblages. Our results highlight the high heterogeneity of these spring systems. Future taxonomic insights can be useful to define the identity of some abundant and dominant taxa not identified at the species level in this study. Their identification is a crucial step for a more precise ecological characterization and comparison of these peculiar spring systems.
