MACROALGAE ASSOCIATED WITH THE MANGROVE VEGETATION OF PAPUA-NEW-GUINEA

The macroalgae associated with the mangrove vegetation of Papua New Guinea, a region which is phycol-ogically poorly known, is investigated. The flora includes the characteristic Bostrychia-Caloglossa' association, and a complement of algae which may be regarded as typical of tropical mangrove communities. In the Madang region, where the mangrove vegetation and the inshore reefs are closely associated, algae more characteristic of coral reef ecosystems occur in the mangroves. Twenty-five species are recorded, 15 Rhodophyta, 5 Phaeophyta, and 5 Chlorophyta, and for each relevant morphosystematic and distributional data are provided. © 1990, IEEE. All rights reserved.
