Candona alchichica (Podocopida: Candonidae), a new ostracod species from saline, tropical Lake Alchichica, Mexico [PDF]
Journal of Limnology, 2016 In North America, most species of the Candonidae family belong to the genus Candona. These species are frequently found in freshwater ecosystems and in sediment sequences, which makes them valuable tools for paleoenvironmental reconstructions.

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

Effects of El Niño on the dynamics of Lake Alchichica, central Mexico [PDF]
Geofísica Internacional, 2003 Lake Alchichica is a deep, warm-monomictic lake in Puebla State, central Mexico. Water temperature, dissolved oxygen and chlorophyll a annual concentration patterns are compared under ENSO and non-ENSO conditions.

A Novel Microbialite-Associated Phototrophic Chloroflexi Lineage Exhibiting a Quasi-Clonal Pattern along Depth. [PDF]
Genome Biol Evol, 2020 Chloroflexales (Chloroflexi) are typical members of the anoxygenic photosynthesizing component of microbial mats and have mostly been characterized from communities associated to hot springs.

Short-term climatic change in lake sediments from lake Alchichica, Oriental, Mexico [PDF]
Geofísica Internacional, 2003 Reduced precipitation in central Mexico is related to ENSO events. These short-term climatic fluctuations can modify mixing-stratification patterns of lake systems, reflected in the sediments deposited at the bottom year after year.

Specific carbonate–microbe interactions in the modern microbialites of Lake Alchichica (Mexico) [PDF]
ISME Journal, 2013 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?

Phenotypic plasticity of life-history traits of a calanoid copepod in a tropical lake: Is the magnitude of thermal plasticity related to thermal variability? [PDF]
PLoS ONE, 2018 According to the Climatic Variability Hypothesis [CVH], thermal plasticity should be wider in organisms from temperate environments, but is unlikely to occur in tropical latitudes where temperature fluctuations are narrow.

Alkaline saline lakes: A chemical evolution experiment evaluating the stability of formaldehyde in an aqueous saline environment [PDF]
HeliyonFormaldehyde condensation in the presence of a mineral catalyst and under alkaline conditions is considered to be a ''messy'' chemical system due to its dependence on the complex chemical equilibrium between the reaction intermediates, which has a ...

16S rDNA-based analysis reveals cosmopolitan occurrence but limited diversity of two cyanobacterial lineages with contrasted patterns of intracellular carbonate mineralization [PDF]
Frontiers in Microbiology, 2014 Cyanobacteria are mainly thought to induce carbonate precipitation extracellularly via their photosynthetic activity combined with the nucleation potential of exopolymeric substances. The discovery in microbialites of the alkaline lake Alchichica (Mexico)
