From: Spatial Competition: Roughening of an Experimental Interface
White clover (T. repens, black area) advancing into perennial ryegrass (L. perenne), from photographs taken during experiment.
Interface length L ≡ Ly = 16 m. June (left), August (center) and October (right) 2010 shown. The interface advances, left to right and roughens; neighboring heights suggest spatial correlation.
