    • Refining the role of phenology in regulating gross ecosystem productivity across European peatlands 

      Koebsch, Franziska; Sonnentag, Oliver; Järveoja, Järvi; Peltoniemi, Mikko; Alekseychik, Pavel; Aurela, Mika; Arslan, Ali Nadir; Dinsmore, Kerry; Gianelle, Damiano; Helfter, Carole; Jackowicz-Korczynski, Marcin; Korrensalo, Aino; Leith, Fraser; Linkosalmi, Maiju; Lohila, Annalea; Lund, Magnus; Maddison, Martin; Mammarella, Ivan; Mander, Ülo; Minkkinen, Kari; et al. [incl. Tuittila, Eeva-Stiina] (Wiley, 2020)
      The role of plant phenology as a regulator for gross ecosystem productivity (GEP) in peatlands is empirically not well constrained. This is because proxies to track vegetation development with daily coverage at the ecosystem ...
