Response to Brinkmann et al. “Re-assembly of 19th century smallpox vaccine genomes reveals the contemporaneous use of horsepox and horsepox-related viruses in the United States”

open access: yesGenome Biology, 2020
We thank Brinkmann and colleagues for their correspondence and their further investigation into these American Civil War Era vaccination strains. Here, we summarize the difficulties and caveats of work with ancient DNA.

Palaeomicrobiology: Application of Ancient DNA Sequencing to Better Understand Bacterial Genome Evolution and Adaptation

open access: yesFrontiers in Ecology and Evolution, 2020
Next generation sequencing (NGS) has unlocked access to the wide range of non-cultivable microorganisms, including those present in the ancient past. The study of microorganisms from ancient sources (palaeomicrobiology) using DNA sequencing now provides ...

Carbon storage and DNA absorption in allophanic soils and paleosols [PDF]

open access: yes, 2014
Andisols and andic paleosols dominated by the nanocrystalline mineral allophane sequester large amounts of carbon (C), attributable mainly to its chemical bonding with charged hydroxyl groups on the surface of allophane together with its physical ...

The immunogenetic impact of European colonization in the Americas

open access: yesFrontiers in Genetics, 2022
The introduction of pathogens originating from Eurasia into the Americas during early European contact has been associated with high mortality rates among Indigenous peoples, likely contributing to their historical and precipitous population decline ...

How Mitochondrial DNA Can Write Pre-History: Kinship and Culture in Duero Basin (Spain) during Chalcolithic and Bronze Age

open access: yesGenealogy, 2023
The chronological period from the beginning of the Chalcolithic Age to the end of the Bronze Age on the Iberian northern sub-plateau of the Iberic Peninsula involves interesting social and cultural phenomena, such as the appearance of the Bell Beaker and,

New insights on single-stranded versus double-stranded DNA library preparation for ancient DNA [PDF]

open access: yes, 2015
An innovative single-stranded DNA (ssDNA) library preparation method has sparked great interest among ancient DNA (aDNA) researchers, especially after reports of endogenous DNA content increases >20-fold in some samples.

American mastodon mitochondrial genomes suggest multiple dispersal events in response to Pleistocene climate oscillations

open access: yesNature Communications, 2020
Pleistocene population dynamics can inform the consequences of current climate change. This phylogeography of 35 complete American mastodon mitochondrial genomes suggests distinct lineages in this species repeatedly expanded northwards and then went ...
