Summary: Hourigan & Reese (1987)

The Hawaiian archipelago is an extremely isolated island group. Hourigan & Reese (1987) noted that the Hawaiian fish fauna is derived from, and has close affinities with, the Indo-west Pacific fauna. However, while it has many endemic species (30% of inshore fishes), there is low species diversity (depauperate). There is local adaptation, but no species radiation. These trends may have been caused by: (1) geographic isolation and current patterns; (2) life history characteristics, particularly dispersal ability, of the fishes; and (3) the extent of adaptive differentiation. Hourigan & Reese (1987) suggested that the isolation of Hawaii is due to its location with respect to unfavourable pacific current patterns, which in turn, determines the marine faunal source.
