Macroalgal cover at month 4 in experimental plots on a fringing reef in Fiji.

Expand/Collapse All

Description

To assess plot colonization by benthic macroalgae at 4 months, photographs of each plot were analysed for the percentage cover of macroalgae using ImageJ (version 1.8.0_121).

These data are depicted in Figure 2c of Clements and Hay (2019).

These data was also funded through:
National Institutes of Health (2 U19 TW007401-10)
Teasley Endowment to the Georgia Institute of Technology

Methods & Sampling

Macroalgal colonization of polycultures and monocultures of each species at 4 months were compared with ANOVA and Tukey's post-hoc tests using a permutation approach (5,000 permutations) in the R (version 3.3.2) package lmPerm (version 2.1.0).

Data Processing Description

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- appended the latitude and longitude coordinates to the data as supplied in the accompanying metadata

Instrument Type

Generic Name: Diving Mask and Snorkel

Generic Description:

A diving mask (also half mask, dive mask or scuba mask) is an item of diving equipment that allows underwater divers, including, scuba divers, free-divers, and snorkelers to see clearly underwater.

Snorkel: A breathing apparatus for swimmers and surface divers that allows swimming or continuous use of a face mask without lifting the head to breathe, consisting of a tube that curves out of the mouth and extends above the surface of the water.
