Micropaleontology & Paleogenetics

Morphological and genetic analyses of organismic remains from terrestrial plants (e.g. pollen) or aquatic taxa (e.g. diatoms, chironomids, cladocerans) facilitate the investigation of spatial and temporal changes in Arctic ecosystems. The laboratories for micropaleontology, genetics and paleogenetics are specialized to either analyze organismic material or recent and ancient environmental DNA from lake sediments archives or permafrost deposits.


Micropaleontology laboratory

  • Extraction of pollen, diatom valves and other microfossils
  • Microscopy (Zeiss Axio, Zeiss Axiovert microscope with manipulator)

Genetic laboratory

  • DNA Isolation of different material (Fast-Prep®-24 Instrument)
  • Metabarcoding and preparation for Illumina sequencing (End-point PCR Cycler, qPCR)
  • Preparation for genome sequencing (Covaris M220 Focused-ultrasonicator™, 4200 TapeStation)
  • Microsatellite analyses
  • Cloning (laboratories with security level S1)

Paleogenetic laboratory

  • Separated from the genetic laboratories (separate building)
  • High degree of purity (UV ceiling lights, separation in pre- and main room)
  • Isolation of ancient DNA from environmental samples (e.g. lake sediment, permafrost)
