Investigations of introduced species in Pearl Harbor; Oahu, Hawaii, from 1996-01-11 to 1996-09-18 (NCEI Accession 0000330)

This study collected or observed a total of 434 species or higher taxa (36 algae, 1 spermatophyte, 338 invertebrate and 59 fish) from the 15 stations sampled, the highest number of taxa that have been collected for any Pearl Harbor study. Ninety six species, or about 22%, are considered to be introduced or cryptogenic. The areas of highest species richness were in the entrance channel and in Rainbow Bay at the northeast head of East Loch where number of taxa were around 150.

Lowest species richness occurred in the areas of high sedimentation and turbidity at the head of West Loch where fewer than 50 taxa occurred. Dendrographs based on Sorensen Indices of Similarity of species composition among stations suggest three types of communities in the harbor, one associated with relatively oceanic conditions in channel areas, one with the highly turbid West Loch sedimentary environment and one with conditions prevailing throughout the rest of the harbor.
