Sub-projects within the TrendDNA consortium

The preserved samples in the Environmental Specimen Bank can be used to reconstruct biodiversity changes in Germany over the last few decades. To this end, terrestrial, limnic and marine samples are genetically analyzed, revealing trends over time.

Terrestrial Habitats

Sample Types:

  • Leaf homogenates (beech, spruce, pine, poplar)
  • Earthworms and earthworm droppings
  • Soil samples


Analyses:

  • Study of leaf-associated arthropod communities
  • Genomic and microbiome analysis of earthworms
  • Analysis of macroorganisms and microorganisms in soil samples



Methods:

  • DNA metabarcoding
  • Shotgun sequencing


Team Members:

  • Trier University
  • Senckenberg Gesellschaft


Limnic Habitats

Sample Types:

  • Sediment samples from the rivers Rhine, Elbe and Danube
  • Zebra mussels



Analyses:

  • Examination of environmental DNA of vertebrates and invertebrates in Suspended Particulate Matter (SPM) samples
  • Examination of commensals and parasites of zebra mussels, as well as their diet (ingested planktonic particles)


Methods:

  • DNA metabarcoding


Team Members:

  • University of Duisburg-Essen
  • Trier University
  • Fraunhofer Institute



Marine Habitats

Sample Types:

  • Mussels
  • Bladderwrack



Analyses:


  • Investigation of commensals and parasites of mussels, as well as their diet (ingested planktonic particles)
  • Study of bladderwrack bacterial communities and associated metazoan communities



Methods:

  • DNA metabarcoding


Team Members:

  • Trier University
