  • Age of the oldest known Homo sapiens from eastern Africa 
    Vidal, Celine M; Lane, Christine S; Asrat, Asfawossen; Barfod, Dan N; Mark, Darren F; Tomlinson, Emma L; Tadesse, Amdemichael Zafu; Yirgu, Gezahegn; Deino, Alan; Hutchison, William; Mounier, Aurélien; Oppenheimer, Clive (Springer Nature Limited, 2022-01-12)
    Efforts to date the oldest modern human fossils in eastern Africa, from Omo-Kibish1,2,3 and Herto4,5 in Ethiopia, have drawn on a variety of chronometric evidence, including 40Ar/39Ar ages of stratigraphically associated ...
  • Fuzzy model-based reconstruction of paleovegetation in Ethiopia 
    von Reumont, Frederik; Schäbitz, Frank; Asrat, Asfawossen (Informa UK Limited, trading as Taylor & Francis Group, 2022-05-31)
    We introduce a new method to compute plant distribution in Ethiopia under paleoclimatic conditions using fuzzy logic. Using a published map of the potential vegetation for Ethiopia we decipher the boundary conditions for ...
  • Hydroclimate changes in eastern Africa over the past 200,000 years may have influenced early human dispersal 
    Schaebitz, Frank; Asrat, Asfawossen; Lamb, Henry F; Cohen, Andrew S; Foerster, Verena; Duesing, Walter; Kaboth-Bahr, Stefanie; Opitz, Stephan; Viehberg, Finn A; Vogelsang, Ralf; Dean, Jonathan; Leng, Melanie J; Junginger, Annett; Ramsey, Christopher Bronk; Chapot, Melissa S; Deino, Alan; Lane, Christine S; Roberts, Helen M; Vidal, Céline; Tiedemann, Ralph; Trauth, Martin H (Springer Nature Limited, 2021-06-14)
    Reconstructions of climatic and environmental conditions can contribute to current debates about the factors that influenced early human dispersal within and beyond Africa. Here we analyse a 200,000-year multi-proxy ...
  • Orbital controls on eastern African hydroclimate in the Pleistocene 
    Lupien, Rachel L; Russell, James M; Pearson, Emma J; Castañeda, Isla S; Asrat, Asfawossen; Foerster, Verena; Lamb, Henry F; Roberts, Helen M; Schäbitz, Frank; Trauth, Martin H; Beck, Catherine C; Feibel, Craig S; Cohen, Andrew S (Springer Nature Limited, 2022-02-24)
    Understanding eastern African paleoclimate is critical for contextualizing early human evolution, adaptation, and dispersal, yet Pleistocene climate of this region and its governing mechanisms remain poorly understood due ...
  • A phytolith supported biosphere-hydrosphere predictive model for southern Ethiopia: insights into paleoenvironmental changes and human landscape preferences since the last glacial maximum 
    Fischer, Markus L.; Bachofer, Felix; Yost, Chad L.; Bludau, Ines J. E.; Schepers, Christian; Foerster, Verena; Lamb, Henry; Schäbitz, Frank; Asrat, Asfawossen; Trauth, Martin H.; Junginger, Annett (MDPI, 2021-10-08)
    During the past 25 ka, southern Ethiopia has undergone tremendous climatic changes, from dry and relatively cold during the Last Glacial Maximum (LGM, 25–18 ka) to the African Humid Period (AHP, 15–5 ka), and back to ...
  • Prediction of genes that function in methanogenesis and CO2 pathways in extremophiles 
    Tilahun, Lulit; Asrat, Asfawossen; Wessel, Gary M.; Simachew, Addis (MDPI, 2021-10-24)
    Gaet’ale (GAL) and Mud’ara (MUP) are two hypersaline ponds located in the Danakil Depression recharged by underground water from the surrounding highlands. These two ponds have different pH, salinity, and show variation ...
