Abstract: | Synopsis Much of the freshwater biota on high Pacific islands is derived from marine ancestors. Traces of this marine origin are seen
in the amphidromous life history patterns of these species. Investigation of the habitat utilization of an assemblage of freshwater
gobies in the Hawaiian Islands indicates some resource partitioning within this group. The three major stream species appear
to exhibit distinct habitat preferences, which in conjunction with their longitudinal zonation in streams may have served
to facilitate their colonization or co-existence. |
