Resolution of the type material of the Asian elephant, Elephas maximus Linnaeus, 1758 (Proboscidea, Elephantidae) [PDF]

open access: yes, 2014
The understanding of Earth’s biodiversity depends critically on the accurate identification and nomenclature of species. Many species were described centuries ago, and in a surprising number of cases their nomenclature or type material remain unclear ...

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 ...

Interrogation of modern and ancient genomes reveals the complex domestic history of cattle [PDF]

open access: yes, 2014
The analysis of mitochondrial and nuclear DNA sequence polymorphisms from modern cattle populations has had a profound impact on our understanding of the events surrounding the domestication of cattle.

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.

Quantitative PCR as a predictor of aligned ancient DNA read counts following targeted enrichment

open access: yesBioTechniques, 2013
Targeted DNA enrichment through hybridization capture (EHC) is rapidly replacing PCR as the method of choice for enrichment prior to genomic resequencing.

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 ...

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 ...

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,

Impact of commercial RNA extraction methods on the recovery of human RNA sequence data from archival fixed tissues

open access: yesBioTechniques
Archival fixed tissues hold key insights into the evolutionary history of RNA viruses and the associated host immune response, yet access to the RNA sequence data is limited by a lack of robust methods for RNA extraction and sequence retrieval from these
