Phylogeny-guided curation reveals widespread misannotation of Asgard archaeal 16S rRNA gene sequences in public databases

Abstract Accurate taxonomic assignment of 16S rRNA gene sequences is essential for the reliable interpretation of microbial community studies based on amplicon sequence data. Yet, it critically depends on the reliability of reference databases such as the Genome Taxonomy Database...

Vulnerable microbial communities in Atacama-Altiplano wetlands: modern analogs of ancient ecosystems with implications for sustainability and conservation

Abstract The Altiplano-Puna plateau lies at ∼4,000 m above sea level in the volcanic Andes cordillera. Together with the adjacent Atacama Desert, it forms one of the most hyperarid regions on the planet. Wetlands are rare, influenced by hydrothermalism and, due to high evaporatio...
