A new record of Avrainvilleacf.erecta (Berkeley) A. Gepp E. S. Gepp (Bryopsidales Chlorophyta) from urbanized estuaries in the Hawaiian Islands

摘要

BackgroundA second species in the siphonous green algal genus Avrainvillea was recently discovered off the island of O‘ahu in the Main Hawaiian Islands. Specimens were collected from Honolulu Harbor, including its entrance channel, and near Ke‘ehi Harbor. These locations are both in Mālama Bay on O‘ahu’s south shore in or adjacent to urbanized estuaries, respectively. In situ observations, morphological and molecular assessments were conducted to examine the alga’s habit and distribution, as well as to assess its putative species identification.
