Title:
2001 Abundance Data Acquired in Support of Invasive Species Distribution Studies at 10 Macroalgal Ecology and Taxonomic Assessment Sites in Hawaii (NODC Accession 0000879)
Abstract:
Abundance data represent estimates of percent cover of species type (coral or algal) in 10 randomly placed quadrats along two 50 meter transect lines of each site. Data are available for 10 sites from Oahu to the Island of Hawaii taken in 2001 in support of the Macroalgal Ecology and Taxonomic Assessment (TEAM) Project. The species for abundance estimates include 11 corals, 5 invertebrates, 33 algals, and 2 benthic types (turf or sand). The role that marine algae play in a coral reef system is often overlooked because of lack of knowledge that they are the primary producers in the system. The coral reef ecosystem in Hawaii contains about ten times more algal species than coral species, some of them regulating space that permits coral recruitment. The primary purpose of the TEAM research program is to provide taxonomic and ecological algal expertise for the Coral Reef Monitoring and Assessment Program (CRAMP). Our group also seeks to develop, implement and assess new methodologies for quantitatively surveying benthic algal communities in the Hawaiian Islands.

Why was the data set created?

(1) To understand better the role that marine algae play in a coral reef systems of Hawaii. (2) To generate an algal species list for each transect line, site and island (3) Collect voucher specimens of all species encountered including alien species, rare species new records and/or new species (4) To classify benthic habitat based on algal community structure (5) To estimate abundance and percent cover of various algal functional forms and species on transect lines.


How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    Date: Unknown (process 1 of 1)
    Quantitative Algal Assessment - As an integral component of the REA teams at least one algal diver quantified and assessed the benthic community. On each of the two 50 m transects that were surveyed at each site five random points along each transect were selected. At each of these locations, the point intercept method was used to estimate percent cover in 10 randomly placed quadrats along two 50 meter transect lines. These quadrat are 1/4 m2 in size and a total of 20 intersections are assessed per quadrat to quantify the benthic community.
