Abstract Ancient DNA and RNA are valuable data sources for a wide range of disciplines. Within the field ancient metagenomics, number published genetic datasets has risen dramatically in recent years, tracking this reuse is particularly important large-scale ecological evolutionary studies individual taxa communities both microbes eukaryotes. AncientMetagenomeDir (archived at https://doi.org/10.5281/zenodo.3980833 ) collection annotated metagenomic sample lists derived from that provide...
After the European colonization of Americas, there was a dramatic population collapse Indigenous inhabitants caused in part by introduction new pathogens. Although is much speculation on etiology Colonial epidemics, direct evidence for presence specific viruses during era lacking. To uncover diversity viral pathogens this period, we designed an enrichment assay targeting ancient DNA (aDNA) from clinical importance and applied it to extracts individuals found hospital chapel (16th–18th...
Aridoamerica and Mesoamerica are two distinct cultural areas in northern central Mexico, respectively, that hosted numerous pre-Hispanic civilizations between 2500 BCE 1521 CE. The division these regions shifted southward because of severe droughts ~1100 years ago, which allegedly drove a population replacement Mexico by Aridoamerican peoples. In this study, we present shotgun genome-wide data from 12 individuals 27 mitochondrial genomes eight archaeological sites across including at the...
<ns3:p>Background Access to sample-level metadata is important when selecting public metagenomic sequencing datasets for reuse in new biological analyses. The Standards, Precautions, and Advances Ancient Metagenomics community (SPAAM, https://spaam-community.org) has previously published AncientMetagenomeDir, a collection of curated standardised sample tables microbial genome generated from ancient samples. However, while information useful identifying relevant samples inclusion projects,...
The ‘red complex’ is an aggregate of three oral bacteria ( Tannerella forsythia , Porphyromonas gingivalis and Treponema denticola ) responsible for severe clinical manifestation periodontal disease. Here, we report the first direct evidence ancient T. DNA in dentin dental calculus samples from archaeological skeletal remains that span Pre-Hispanic to Colonial period Mexico. We recovered twelve partial genomes observed a distinct phylogenetic placement samples, suggesting strains present...

Abstract Although Brazil was inhabited by more than 3,000 Indigenous populations prior to European colonization, today’s peoples represent less 1% of Brazil’s census population. Some the decimated communities belonged so-called “Botocudos” from central-eastern Brazil. These are thought a case long-standing genetic continuity bearing strong craniometric resemblance that oldest Americans (“Paleoamericans”). Yet, little is known about their origins and relationship other Native Americans, as...

Abstract Aridoamerica and Mesoamerica are two distinct cultural areas that hosted numerous pre-Hispanic civilizations between 2,500 BCE 1,521 CE. The division these regions shifted southward due to severe droughts ca. 1,100 years ago, allegedly driving demographic changes population replacement in some sites central Mexico. Here, we present shotgun genome-wide data from 12 individuals 26 mitochondrial genomes eight archaeological across Mexico, including at the shifting border of...
