From August 2019 to June 2021, viscous oil residues appeared along the Brazilian coast
spanning 11 states and more than 3,000 km of tropical shoreline. Forensic results published …

The record of the coevolution of oxygenic phototrophs and the environment is preserved in
three forms: genomes of modern organisms, diverse geochemical signals of surface …

The geochemical analysis and experimental simulation are comprehensively used to
systematically study the hydrocarbon generation material, organic matter enrichment and …

Studies of alkaline lakes have critical biological–environmental–economic properties, but
deep-time alkaline lakes are challenging to investigate. Lipid biomarkers can provide …

The negative organic carbon isotope excursion (CIE) associated with the end-Triassic mass
extinction (ETE) is conventionally interpreted as the result of a massive flux of isotopically …

For most of Earth's history life was microbial, with archaeal and bacterial cells mediating
biogeochemical cycles through their metabolisms and ecologies. This diversity was …

It is established that green algae and land plants progressively colonized freshwater and
terrestrial habitats throughout the Paleozoic Era, but little is known about the ecology of …

The breakup of Gondwana resulted in sedimentary deposits recording lacustrine to marine
environmental transitions in the South Atlantic rift basins during the Early Cretaceous …
