Percent tissue mortality of corals in experimental plots at month 4 and 16 on a fringing reef in Fiji.

Expand/Collapse All

Description

Each coral in each plot was visually examined from all sides and the percentage tissue mortality
was estimated and assigned in 10% classes (0, 10 and 20% and so on, up to 100%).

These data are depicted in Figure 2b 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

To assess differences in percentage-tissue and whole-colony mortality at 16 months between conspecific corals in monocultures versus polycultures, we first separately averaged the percentage tissue and mortality of individual corals in each plot. Mean tissue and colony mortalities of conspecifics in monoculture and polyculture plots at each time point were then compared separately using Fisher– Pitman permutation tests (10,000 permutations) in the R (version 3.3.2) package 'coin' (version 1.2–2).

Instruments

Diving Mask and Snorkel

Supplied Name: snorkel

Supplied Description:

These data were collected near shore via snorkel.

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.

Parameters

Date and time formats are described in python strftime() syntax.
