Clorofila a fitoplanctónica en el lago tropical profundo Alchichica: un registro de largo plazo (1999-2010)

, 2016
La variación temporal de la biomasa del fitoplancton ha sido ampliamente estudiada en los lagos templados; sin embargo, los estudios en los sistemas acuáticos tropicales son escasos y más aún las investigaciones a largo plazo. Con el fin de reconocer los

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

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 ...

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.
