Experiments to quantify the effects of vermetids on skeletal growth and survival in Moorea, French Polynesia from (Vermetids_Corals project)

Expand/Collapse All

Description

Researchers examined the effects of vermetids on the growth and survival of three species of coral in Moorea, French Polynesia as well as the relationship between the proportion of dead coral and the number of vermetids.

Methods & Sampling

Between June 2-10, 2006, six experiments were set up to quantify the effects of vermetids on skeletal growth and survival. The four focal species were: Porites lobata, Porites rus, Pocillopora and Montipora, which were at a site in the Maharepa lagoon (inshore) and two species (Porites lobata and Pocillopora) at another site (West Temae or toe). Corals were attached to plastic bases and weighed using the bouyant method (Davies 1989) and then placed onto to the reefs in triplicate.

Reefs where corals were placed had local vermetid densities (n=12). Half of the reefs were then used as experimental reefs and vermetids were removed. Focal corals were collected after 47 days and re-weighed to assess growth. After weighing, corals were returned to the experimental reefs. After 217-255 days on 13 January 2007, the proportion of coral surface area that was alive was estimated.

Data Processing Description

asin_survival = estimate of survival after the end of the experiment - 217-225 days after initiation

Surival = arcsin(square root(proportion alive)

delta_mass = change in mass, final-initial mass
