A minimally destructive protocol for DNA extraction from ancient teeth

open access: yesbioRxiv, 2020
Ancient DNA sampling methods—although optimized for efficient DNA extraction—are destructive, relying on drilling or cutting and powdering (parts of) bones and teeth. As the field of ancient DNA has grown, so have concerns about the impact of destructive

Ceramic materials lead to underestimated DNA quantifications : a method for reliable measurements [PDF]

open access: yes, 2010
In the context of investigating cell-material interactions or of material-guided generation of tissues, DNA quantification represents an elective method to precisely assess the number of cells attached or embedded within different substrates. Nonetheless,

A simple genetic method to distinguish mule deer and bighorn sheep fecal pellets and its application to detecting bighorn sheep colonization events in California

open access: yesCalifornia Fish and Wildlife Journal, 2023
Bighorn sheep (Ovis canadensis) habitat frequently is geographically discontinuous and the metapopulation model fits this species well. Consequently, extinction-colonization dynamics are important and need to be monitored.
