Searching for biosignatures in sedimentary rocks from early Earth and Mars
The recognition of past habitable environments on Mars has increased the urgency to
understand biosignature preservation in and characterize analogues of these environments …

Integrative analysis of the mineralogical and chemical composition of modern microbialites from ten Mexican lakes: What do we learn about their formation?
Interpreting the environmental conditions under which ancient microbialites formed relies
upon comparisons with modern analogues. This is why we need a detailed reference …

A review of microbial‐environmental interactions recorded in Proterozoic carbonate‐hosted chert
The record of life during the Proterozoic is preserved by several different lithologies, but two
in particular are linked both spatially and temporally: chert and carbonate. These lithologies …

Spatiotemporal variations in microbial diversity across the three domains of life in a tropical thalassohaline lake (Dziani Dzaha, Mayotte Island)
Thalassohaline ecosystems are hypersaline environments originating from seawater in
