Geomicrobiology of Alchichica alkaline lake microbialites (Mexico)

, 2012
Les stromatolites sont des structures organo-sédimentaires formées grâce à l'activité des microorganismes. Ils dominent le registre fossile Précambrien et sont parmi les plus anciennes traces potentielles de vie sur Terre (datées à 3,5 Ga). Cependant les processus biotiques et abiotiques à l'origine de leur formation restent peu compris et ouvrent des ...

Huntite [CaMg3(CO3)4], a rare carbonate phase formed during early diagenesis in modern microbialites.

International audienceMicrobialites are sedimentary rocks formed under the influence of microbial communities and environmental factors, hence, particularly suited to look for traces of life and reconstruct palaeoenvironments. However, the mineral phases

Preliminary investigations on picoplankton-related precipitation of alkaline-earth metal carbonates in meso-oligotrophic lake Geneva (Switzerland)

, 2013
In the course of a routine water-quality survey in meso-oligotrophic lake Geneva (Switzerland), suspended matter was collected by filtration on 0.2 μm membranes in July and August 2012 at the depth of maximal chlorophyll a (Chl a) concentration (2 mg m–3)

Seasonal and spatial dynamics of a ciliate assemblage in a warm-monomictic Lake Alchichica (Puebla, Mexico)

, 2008
"The distribution of the ciliate assemblage was surveyed along a depth gradient in the maar crater, athalassohaline, warm monomictic Lake Alchichica (Puebla, Mexico) from June 2003 to October 2006 (monthly). DAPI staining was employed to count ciliates while the Quantitative Protargol Staining was used for their identification.
