Structure and floristic composition of the Heard Island "Pool Complex" Community
The stratigraphy, hydrology and vegetation of the Heard Island (sub-Antarctic; 53 deg. 05'S, 73 deg. 30'E) 'pool complex' bogs are described. Spatial variation in processes that might have contributed to their formation are discussed. This community occurs where drainage has been...
