Standard phycological methods were followed (see Tsuda and Abbott 1985). Macro-algae (large
seaweeds of size 5 cm or more) were identified and pressed in a standard plant-presser, and if
necessary parts of the plant were removed for anatomical assessment to confirm the species
identification. Macro-algal epiphytes were removed and identified. Algae smaller than 5 cm were
identified using a Nikon SMZ645 dissecting microscope and an Olympus CX31 compound
microscope. Smaller specimens were mounted on slides in a 50% Karo solution (corn syrup in
water with a few thymol crystals). Photographs were taken of some of the algae using a Nikon
Coolpix 990 digital camera.
Each specimen analyzed was designated a field number, which was entered into a log-book. The
field number began with the letters AS (for American Samoa) followed by a consequent number.
These were later computed into a Microsoft Excel Sheet for further documentation and analysis.
Voucher specimens are deposited in the Herbarium Pacificum of Bishop Museum (Honolulu), with
some duplicate specimens at the South Pacific Regional Herbarium at the Marine Studies
Programme, the University of the South Pacific, Fiji.
