Diatoms of North AmericaDescription: Kathleen presented published and new
data from analyses using ancient sedimentary DNA to track changes in
diatom communities during past millennia. Metabarcoding and metagenomic
approaches from lake and marine sediment cores will be discussed. The
studies on lakes will focus on the applications of diatom DNA to
understand cryptic diversity and community changes along with
terrestrial vegetation change in Arctic Siberia. The studies on marine
systems will focus on using diatom DNA to understand past sea ice and
sea surface temperatures in the Northern Pacific Ocean.
Target audience: Anyone interested in biomonitoring diatoms using DNA, cryptic diatom diversity, and those interested in paleoecology. Please note, we will respect the speaker's request to delay uploading the recording until the presented data become published.
