Macroalgal assemblages in New Zealand: structure, interactions and demography. Hydrobiologia 192
structure Quantitative descriptions of macroalgal distributions from low intertidal regions to a sublittoral depth of 20 m are presented for rocky reefs from several localities ranging over 16 ° latitude in New Zealand. These include the northern and southern main islands as well as the Chatham Isla...
