A note on the effects of an individual large rainfall event on saline Lake Alchichica, Mexico
The present study reports on perturbations of the water column by large rainfall at Lake Alchichica, a saline lake in Central Mexico. Alchichica is located in the "Llanos de San Juan," a high-altitude plateau with a minimum elevation of 2,300 m above sea

Rapid formation of mature microbialites in Lake Alchichica, Mexico [PDF]
Summary Microbialites are emblematic sedimentary rocks formed by phylogenetically and metabolically complex microbial communities thriving under specific physicochemical conditions. Most microbialites are photosynthesis‐based ecosystems frequently formed by carbonates, thereby capturing inorganic carbon in the ...

The hidden role of dissolved organic carbon in the biogeochemical cycle of carbon in modern redox-stratified lakes [PDF]
The dissolved organic carbon (DOC) reservoir plays a critical role in the C cycle of marine and freshwater environments because of its size and implication in many biogeochemical reactions.

Formation of Magnesium Carbonates on Earth and Implications for Mars
Abstract Magnesium carbonates have been identified within the landing site of the Perseverance rover mission. This study reviews terrestrial analog environments and textural, mineral assemblage, isotopic, and elemental analyses that have been applied to establish formation conditions of magnesium carbonates.

20 Years of Global Change on the Limnology and Plankton of a Tropical, High-Altitude Lake
The present long-term (1993–2013) study was aimed at identifying the effects of global change on the environmental characteristics and the plankton community of the tropical, high-altitude Lake Alchichica, Puebla, Mexico.

Specific carbonate-microbe interactions in the modern microbialites of Lake Alchichica (Mexico). [PDF]
Abstract The role of microorganisms in microbialite formation remains unresolved: do they induce mineral precipitation (microbes first) or do they colonize and/or entrap abiotic mineral precipitates (minerals first)? Does this role vary from one species to another? And what is the impact of mineral precipitation on microbial ecology?

Alkaline phosphatases in microbialites and bacterioplankton from Alchichica soda lake, Mexico [PDF]
Dissolved organic phosphorus utilization by different members of natural communities has been closely linked to microbial alkaline phosphatases whose affiliation and diversity is largely unknown. Here we assessed genetic diversity of bacterial alkaline phosphatases phoX and phoD, using highly diverse microbial consortia (microbialites and ...
