International collaborator: Extraction of ancient DNA from the Atacama rodent fossil coprolites to reconstruct vegetation change.

Visiting from:  Pontifica Universidad Catolica de Chile

2016

Project: Analyzing ancient DNA, plant macrofossils and N isotopes in fossil rodent middens from the Atacama desert (Chile) to reconstruct past climate and biotic change during the last 30,000 years. During her visit to Landcare she extracted ancient DNA from the Atacama rodent fossil coprolites to reconstruct vegetation change and complement their records. DNA of parasites and plant pathogens were also analysed from the middens to reveal new insights from the Atacama Desert.
