    • Crown plasticity enables trees to optimize canopy packing in mixed-species forests 

      Jucker, Tommaso; Bouriaud, Olivier; Coomes, David A. (Wiley on behalf of the British Ecological Society, 2015-03-10)
      1. It has been suggested that diverse forests utilize canopy space more efficiently than species-poor ones, as mixing species with complementary architectural and physiological traits allows trees to pack more densely. ...
