Coral colony interactions (Pocillopora and Acropora) from field observations at LTER sites in Moorea, French Polynesia in 2014 (MCR LTER project, OA coral adaptation project)

Abstract:

Interspecific and intraspecific interaction metrics for Pocillopora verrucosa and Acropora hyacinthus coral colonies were acquired from field observations in Moorea, French Polynesia in 2014. Colony counts and interaction observations were made using photoquadrats.

Description

These data were utilized in Evensen & Edmunds, 2016.

Other datasets utilized in Evensen and Edmunds, 2016:
* coral growth - https://www.bco-dmo.org/dataset/683932
* seawater chemistry - https://www.bco-dmo.org/dataset/684541

Methods & Sampling

Data is from the analysis of photoquadrats taken on the fore reef of MCR LTER sites 1 and 2. Photoquadrats (0.25 m2) were used to quantify the frequency of interactions between adjacent Pocillopora colonies, and between adjacent colonies of Pocillopora and Acropora. Colonies of each genus were inferred to be interacting and competing for space when they were <5 mm apart. The number of colonies inferred to be engaged in spatial competition based on analyses of the photoquadrats was expressed as a percentage of the total number of Pocillopora and Acropora.

Coral collection occurred in 2014 and was conducted at ‘LTER1 and LTER2’ (~1.5 km apart; n = 40 site−1 ) on the north shore of Moorea.

Data Processing Description

Physical conditions in the flumes were analyzed with a two-way ANOVA, with pCO2 as a fixed
effect and flume a random factor nested in each treatment. Calcification, horizontal growth, and
vertical growth collectively were analyzed in multivariate framework using mixed effects
PERMANOVA, with pCO2 as a fixed, between plot effect, flume as a random factor nested in
each treatment, and arrangement as a fixed, split-plot effect in each flume.

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* blank values replaced with no data value 'nd'
* all values were rounded to three decimal places if more than that
* latitude and longitude for LTER1 and LTER2 sites added to data
