Assessing the validity of a calcifying oral biofilm model as a suitable proxy for dental calculus

B. P. Bartholdy, I. M. Velsko, S. Gur-Arieh, Z. Fagernäs, C. Warinner, A. G. Henry

This study validates a calcifying oral biofilm model as a proxy for dental calculus by comparing its microbial and mineral composition to natural calculus.

A glimpse of the paleome in endolithic microbial communities

C.-E. Wegner, R. Stahl, I. M. Velsko, A. Huebner, Z. Fagernaes, C. Warinner, R. Lehmann, T. Ritschel, K. U. Totsche, K. Kuesel

The paper investigates endolithic microbial communities in rock samples, recovering DNA and revealing paleome signatures with increased chemolithoautotrophs and aromatic hydrocarbon breakdown potential.

High conservation of the dental plaque microbiome community across populations with differing subsistence strategies and levels of market integration

I. M. Velsko, S. Gallois, R. Stahl, A. G. Henry, C. Warinner

This study finds that dental plaque microbiomes are highly conserved across populations with different diets and lifestyles, with variation mainly linked to tooth location and hygiene practices rather than diet.

Ancient dental calculus preserves signatures of biofilm succession and inter-individual variation independent of dental pathology

I. M. Velsko, L. Semerau, S. A. Inskip, M. I. Garcia-Collado, K. Ziesemer, M. Serrano Ruber, L. Benitez de Lugo Enrich, J. M. Molero Garcia, D. Gallego Valle, A. C. Pena Ruiz, D. Salazar Garcia, M. L. Hoogland, C. Warinner

The paper analyzes dental calculus from 19th-century individuals to assess microbial signatures related to smoking and oral health, finding no link between pipe notches and dental pathologies or microbial composition.

Selection of appropriate metagenome taxonomic classifiers for ancient microbiome research

I. M. Velsko, L. A. F. Frantz, A. Herbig, G. Larson, C. Warinner

This study evaluates how ancient DNA damage affects taxonomic classification accuracy in metagenomic datasets using five classifiers, finding that program-specific biases outweigh damage effects.
