Prokaryotic and eukaryotic community structure in field and cultured microbialites from the alkaline Lake Alchichica (Mexico). [PDF]
PLoS One, 2011 The geomicrobiology of crater lake microbialites remains largely unknown despite their evolutionary interest due to their resemblance to some Archaean analogs in the dominance of in situ carbonate precipitation over accretion.

Dynamic response to mountain breeze circulation in Alchichica, a crater lake in Mexico [PDF]
Geophysical Research Letters, 2006 In this paper we discuss the dynamic response to mountain breeze circulation in Alchichica, a deep crater lake in Mexico. A numerical model was used to simulate integrated drift currents based on wind data sampled at l-h intervals.

A note on the effects of an individual large rainfall event on saline Lake Alchichica, Mexico
Environmental Geology, 2007 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

Planktonic microbial communities from microbialite-bearing lakes sampled along a salinity-alkalinity gradient. [PDF]
Limnol Oceanogr, 2022 Abstract Continental freshwater systems are particularly vulnerable to environmental variation. Climate change‐induced desertification and the anthropogenic exploitation of hydric resources result in the progressive evaporation and salinization of inland water bodies in many areas of the globe.

Micropearls and other intracellular inclusions of amorphous calcium carbonate: an unsuspected biomineralization capacity shared by diverse microorganisms. [PDF]
Environ Microbiol, 2022 Summary An unsuspected biomineralization process, which produces intracellular inclusions of amorphous calcium carbonate (ACC), was recently discovered in unicellular eukaryotes. These mineral inclusions, called micropearls, can be highly enriched with other alkaline‐earth metals (AEM) such as Sr and Ba.

Hydrochemistry and microbialites of the alkaline crater lake Alchichica, Mexico [PDF]
Facies, 2011 The structure, mineralogy, and accretion processes of the modern and subfossil cyanobacterial microbialites from the alkaline crater lake Alchichica (Puebla, Mexico) were studied, along the lake’s bathymetry and hydrochemistry. The recent lowering of the lake level had exposed microbialitic carbonate mounds and crusts, which emerged up to 2 m above the

Stromatolites in Crater-Lake Alchichica and Bacalar Lagoon
Cuatro Ciénegas Basin: an Endangered Hyperdiverse Oasis, 2020 Extant stromatolites have been considered ecological similes to their ancient counterparts. We now know that these microbial assemblages are composed of a great diversity of microbes, which couple and intertwine their metabolic capabilities to create self-sustained microbial ecosystems.

Untangling the Primary Biotic and Abiotic Controls on Oxygen, Inorganic and Organic Carbon Isotope Signals in Modern Microbialites. [PDF]
GeobiologyABSTRACT Microbialites are organo‐sedimentary structures formed throughout most of the Earth history, over a wide range of geological contexts, and under a multitude of environmental conditions affecting their composition. The carbon and oxygen isotope records of carbonates, which are most often their main constituents, have been used as a widespread ...
