Factors influencing structure and dynamics of subtidal assemblages on walls at a south eastern Australian rocky reef [PDF]

open access: yes, 2003
Assemblages on vertical surfaces at a Rocky Reef at Flinders Islet, South Eastern Australia differ in structure. Tall wall (> 4 m) assemblages are highly diverse, while low wall (1-2 m) assemblages are characterised by low diversity. Abundance of the sea
