Description

Fifty-nine species of marine benthic algae are reported for the first time from the coral reefs of isolated Swains Island, American Samoa, based on collections made during February 2002, 2004, 2006, and March 2008 under the auspices of the U.S. National Oceanic and Atmospheric Administration. The collections include 4 species of blue-green algae (cyanobacteria), 38 species of red algae, 3 species of brown algae and 14 species of green algae. Based on their frequency of occurrence at different stations during the 4 cruises, Rhipilia geppiorum and Microdictyon umbilicatum were considered the most widely distributed species during the months of February and March. Twenty-eight species represent new records for the Samoan Archipelago (American Samoa and Samoa).

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 182 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Sampling Methods

Swains Island was visited in 2002, 2004, 2006, and 2008 as part of the U.S. National Oceanic and Atmospheric Administration’s (NOAA) Pacific Islands Fisheries Science Center’s (PIFSC) Coral Reef Ecosystem Division’s (CRED) Reef Assessment and Monitoring Program (RAMP). Algal samples were collected by hand by scuba divers at 12 permanently established monitoring sites and 1 incidental site (see Appendix) following the protocol of Preskitt et al. (2004), and immediately frozen.

Study Extent Swains Island, American Samoa

Method step description:

  1. Prior to taxonomic examination, plastic bags of frozen algae from each station were thawed in tap water. Thawed seawater was poured carefully from the bag and replaced with 4% formalin in seawater to prevent the fragile turf algae and epiphytes from decomposing. The collections were examined using a dissecting microscope, and all epiphytes and turf were separated. The small specimens were mounted on glass slides by decalcifying with 10% hydrochloric acid, staining with aniline blue and mounting with 30% corn syrup (Karo) with phenol. Larger specimens were mounted on segments of herbarium paper; 5 specimens were also preserved in vials with 4% formalin in seawater. The small quantities of non-processed specimens from each station were consolidated into separate jars and preserved in 4% formalin in seawater. The retention of these specimens was to allow us to revisit the site collection, if needed, during our critical taxonomic reexamination of specimens, including epiphytes.
