Abstract: Quantitative and qualitative surveys were conducted on five of the
main Hawaiian Islands to determine the current distribution of nonindigenous
algae and to assess the level of impact that these algal species pose to Hawai'i's
marine ecosystems. Maps were generated to examine the spread of these organisms
from initial sites of introduction and to assimilate information regarding
habitat characteristics that appear to make some sites more susceptible to
invasion than others. Blooms of native invasive algae were also documented
when encountered. The potential for vegetative propagation via fragmentation
was examined experimentally as a mode of reproduction for four of the most
common species of nonindigenous algae in Hawai'i. This research has demonstrated
that each of these algal species currently has a distinctive distribution and
reproductive strategies appear to vary among species. More research is needed
to further understand the competitive strategies and unique ecological characteristics
that allow these nonindigenous species to become highly successful in
the Hawaiian Islands.
