      Mbufong, Herbert N.; Lund, Magnus; Aurela, Mika; Christensen, Torben Röjle; Eugster, Werner; Friborg, Thomas; Hansen, Birger Ulf; Humphreys, Elyn R.; Jackowicz-Korczyński, Marcin; Kutzbach, Lars; Lafleur, Peter M.; Oechel, Walter C.; Parmentier, Frans-Jan W.; Rasse, Daniel; Rocha, A.V.; Sachs, Torsten; Van Der Molen, Michiel K.; Tamstorf, M.P. (Journal article; Peer reviewed, 2014-09-15)
      This paper aims to assess the spatial variability in the response of CO2 exchange to irradiance across the Arctic tundra during peak season using light response curve (LRC) parameters. This investigation allows us to better ...
    • Genetic yield gains of winter wheat in Germany over more than 100 years (1895-2007) under contrasting fertilizer applications 

      Ahrends, Hella Ellen; Eugster, Werner; Gaiser, Thomas; Rueda-Ayala, Victor; Hüging, H.; Ewert, F.; Siebert, Stefan (Journal article; Peer reviewed, 2018-09-27)
      For highly productive regions such as Germany, the increase of wheat grain yields observed throughout the 20th century is largely attributed to the progress in crop breeding and agronomic management. However, several studies ...
    • Nutrient supply affects the yield stability of major European crops—a 50 year study 

      Ahrends, Hella Ellen; Siebert, Stefan; Rezaei, Ehsan Eyshi; Seidel, Sabine Julia; Hüging, Hubert; Frank, Ewert; Döring, Thomas; Rueda-Ayala, Victor; Eugster, Werner; Gaiser, Thomas (Peer reviewed; Journal article, 2020-12-18)
      Yield stability is important for food security and a sustainable crop production, especially under changing climatic conditions. It is well known that the variability of yields is linked to changes in meteorological ...
