“…The particular ecology of the new Chamaepinnularia species is highlighted by the presence of several taxa in the same samples such as Crenotia thermalis, Fragilaria famelica, Navicula sanctamargaritae, N. veneta, Nitzschia vitrea, Pinnularia kuetzingii, Sellaphora labernardierei, species found in other mineral springs in Europe (Krammer 2000, Lange-Bertalot 2001, Stavreva-Veselinovska & Todorovska 2010, Wojtal 2013, Beauger et al 2015, 2020, Hindáková & Hindák 2015.…”

“…This highland region in the middle of Southern France is influenced by oceanic, continental and Mediterranean climates. On each bank of the Allier River, between the cities of Vic-le-Comte and Mirefleurs (Puy-de-Dôme, Auvergne, Massif Central, France), several well-known springs (Beauger et al 2016(Beauger et al , 2020 are located just above two principal fault systems, which are certainly inherited from the Tardi-Hercynian period (Michon 2000).…”

“…Among the communities thriving in these habitats are diatoms and it is well known that mineral springs host important biodiversity and specific biocenoses (species adapted to the constraints imposed by these ecosystems) (Wojtal 2013, Beauger et al 2015, 2020, Lai et al 2019a.…”

“…Thus, living organisms in mineral springs are often unique, with very specific traits and distribution patterns (Wojtal 2013, Segadelli et al 2015, Lai et al 2019b, Beauger et al 2020.…”

During a survey done on the mineral springs in the French Massif Central region, a new Chamaepinnularia species (Bacillariophyceae) was found and is hereby described: Chamaepinnularia salina Beauger, C.E.Wetzel, Allain & Ector sp. nov. This new small species, with valves linear with almost parallel margins, is formally described using light and scanning electron microscopy. The central area is rectangular, forming a rather broad fascia and the raphe is straight, filiform located on an elevated sternum. Virgae between striae are developed. The ecological preferences of Chamaepinnularia salina are presented. This species is mainly in mineral springs with Na-K-HCO3 water type.

“…In Lai et al (2019a), the species richness of mineral springs sampled in Auvergne and Sardinia varied between 2 and 14. Also in Beauger et al (2020), 17 springs of the Auvergne region were sampled with a richness ranging between 2 and 21 (mean: 9). Lai et al (2019c) sampled several Mediterranean karst springs, the richest spring was Sa Vena Manna-Sedini with 26 species detected while the mean of richness of the 8 springs sampled was 8.…”

La source de la Poix est une particularité géologique du Massif central français car elle est connue pour être bitumineuse associée à de l’eau salée, du méthane et des traces d’hydrogène sulfuré. Entre mars 2017 et juin 2020, trois prélèvements ont été effectués en raclant les diatomées sur la couche de bitume. De plus, les conditions physiques et chimiques ont été examinées. Il apparaît que la conductivité de l’eau salée est supérieure à celle de l’océan, entraînant le développement de certaines espèces de diatomées saumâtres, observées pour certaines d’entre elles sur les sédiments intertidaux ou dans les estuaires. Même si les conditions abiotiques étaient extrêmes pour ces algues, la biodiversité était élevée et révèle des espèces ayant une grande capacité à supporter des concentrations et des fluctuations de salinité élevées.
