    • Changing contributions of stochastic and deterministic processes in community assembly over a successional gradient 

      Måren, Inger Elisabeth; Kapfer, Jutta; Aarrestad, Per Arild; Grytnes, John-Arvid; Vandvik, Vigdis (Journal article; Peer reviewed, 2017)
      Successional dynamics in plant community assembly may result from both deterministic and stochastic ecological processes. The relative importance of different ecological processes is expected to vary over the successional ...
