Fig 2.
Digital complexity values for Colombia and Chankanaab reefs.
Results for the other reefs are presented in the S3 File. (a) Orthomosaic, (b) DEM (Digital elevation model), (c) DGC (digital global complexity) highlighting the historical contributions to reef structure, and (d) DLC (digital local complexity), showing the biological contributions from live coral communities.
Fig 3.
In situ (chain method), and total digital complexity (DGC + DLC) per reef.
The ordering of reefs follows a north-to-south direction. The black lines represent the median values, highlighting the variation among reefs. The total digital complexity considers 380 m2 of analysis.
Fig 4.
DGC was calculated only beneath the areas where live corals were present. The ordering of reefs follows a north-to-south direction. The columns represent the median values, and the bars indicate the standard error.
Fig 5.
DLC values per reef, which is the structural complexity contributed by live coral cover.
The ordering of reefs follows a north-to-south direction. The columns represent the median values, and the bars indicate the standard error.
Fig 6.
Contribution of coral groups to DLC in the CRNP.
A and B indicate statistically significant differences (p < 0.05) while C shows no significant differences (p > 0.05), among coral groups.
Fig 7.
DLC and coral cover grouped by morphological groups.
a) Branching, b) Meandroid, c) Flower and Solitary, d) Agariciid) and e) Mound and Boulder.
Fig 8.
Relative coral cover for each reef: a) species cover grouped by morphological groups per reef and b) morphological groups coverage across all reefs.
The species are grouped in morphological categories according to the AGRRA protocol, with detailed information about species and groups available in S2 File.
