Molecular ecology of microbial mats [PDF]
FEMS Microbiology Ecology, 2014 Phototrophic microbial mats are ideal model systems for ecological and evolutionary analysis of highly diverse microbial communities. Microbial mats are small-scale, nearly closed, and self-sustaining benthic ecosystems that comprise the major element cycles, trophic levels, and food webs.

Microbial mat ecosystems: Structure types, functional diversity, and biotechnological application
Electronic Journal of Biotechnology, 2018 Microbial mats are horizontally stratified microbial communities, exhibiting a structure defined by physiochemical gradients, which models microbial diversity, physiological activities, and their dynamics as a whole system.

Frontiers in Marine Science, 2021 The hypersaline lagoon system of Araruama (HLSA) is one of the largest in the world and one of the most important sources of evaporative salt in Brazil. The biogeochemical characteristics of this lagoon system led it to be considered a Precambrian relic.

Sulphur cycling in a Neoarchaean microbial mat [PDF]
Geobiology, 2017 AbstractMultiple sulphur (S) isotope ratios are powerful proxies to understand the complexity of S biogeochemical cycling through Deep Time. The disappearance of a sulphur mass‐independent fractionation (S‐MIF) signal in rocks <~2.4 Ga has been used to date a dramatic rise in atmospheric oxygen levels.

Eucaryotic Diversity in a Hypersaline Microbial Mat [PDF]
Applied and Environmental Microbiology, 2008 ABSTRACT To determine the eucaryotic diversity of the hypersaline Guerrero Negro microbial mat, we amplified 18S rRNA genes from DNA extracted from this mat and constructed and analyzed clone libraries. The extent of eucaryotic diversity detected was remarkably low, only 15 species among 890 clones analyzed.

Regulation of electron transfer processes affects phototrophic mat structure and activity
Frontiers in Microbiology, 2015 Phototrophic microbial mats are among the most diverse ecosystems in nature. These systems undergo daily cycles in redox potential caused by variations in light energy input and metabolic interactions among the microbial species.

Daily Rhythmicity in Coastal Microbial Mats [PDF]
, 2021 To understand the ecological role of circadian rhythms in prokaryotes, we often move from an initial observation in nature to an in-depth analysis of isolated species under laboratory conditions. The other way around is less common: newly found insights on circadian control of microbial physiology and metabolic interactions are rarely tested in the ...

Cyanobacterial and chemical composition of the stromatolites in Salgada lagoon, Neogene of Rio de Janeiro state, Brazil [PDF]
Geologia USP. Série Científica, 2013 Salgada lagoon is a coastal aquatic body in northern Rio de Janeiro state. The geological evolution of the lagoon is associated with the oscillation of sea level during the Late Neogene.
