Colonisation vs. disturbance: the effects of sustained ice-scouring on intertidal communities
Shoreline plant and animal communities close to a retreating tidewater glacier on the sub-Antarctic island of South Georgia displayed a series of physical and biological gradients from the open sea to the glacier terminus. These included increasing scouring intensity caused by floating and/or ground...
