In the proposed project we aim to upscale the GMR’s role as ecosystem engineer to the landscape scale and determine present and past population dynamics of GMRs in the afro-alpine ecosystem and the upper Ericaceous Belt to resolve the presence of humans in the Bale Mts. To do so, we will link ground data on this ecosystem engineer and on vegetation and environmental data derived from remote sensing and compare current and aDNA data of GMRs and their burrows to reconstruct the landscape history.


  1. Participation in the 2011 DFG supported reconnaissance to Bale Mts.
  2. Pilot data by projects C2/P3: identification of endemic plant species exclusively found on GMR mounds,
    first mapping of GMR mound assemblies
  3. Excavation of bones by P1 indicating that Middle Stone Age foragers largely exploited this endemic
    food resource


  1. Determination of the role of the GMR as synanthropic landscape engineer through the interrelation between GMRs, environmental variables (humidity, vegetation/paludification) and human impact (livestock grazing,
    fire clearing of Erica)
  2. Determination of the population dynamics of the species through the analysis of the current population genetic structure at the landscape scale.
  3. Quantification of the spatial distribution of the vegetation and combine those data with GMR distribution data to derive the relationship between the two datasets. We will then link the transfer function between the vegetation and the GMRs to remote sensing data to upscale the impact of GMRs as ecosystem engineer to the landscape scale.
  4. Reconstruction of the landscape history by ….
      ⦁ Combination of phylogeographic analyses and aDNA analyses and to resolve historical processes responsible for the present  distribution of GMRs.
      ⦁ Dating of excavated material of underground burrows of GMRs to reconstruct the landscape history.
