Metagenomic sequencing applied to petroglyphs sites in the Negev desert

Petroglyphs sites exist all over the world and are one of the earliest forms of mankind expression and precursor to art. Despite their outstanding value, comprehensive research on conservation and preservation of rock art is minimal, especially when related to biodeterioration. For this reason, the main objective of this study was to explore the factors involved in the degradation of petroglyphs sites in the Negev desert of Israel, with a focus on biodegradation processes.
