Supplemental Information

Figure 1

Figure 1. Location of 16 reef stations from eight areas in Puerto Rico: Isla Desecheo, Isla de Mona, Rincón, Mayagüez, Cabo Rojo, Guánica, Ponce, and Isla de Vieques.

DOI: 10.7287/peerj.preprints.2898v1/supp-1

Figure 2

Variations of mean coral cover (%) between monitoring surveys at: a) Isla de Vieques, b) Ponce, c) Guánica, d) Cabo Rojo, e) Mayagüez, f) Rincón, g) Isla de Mona, and h) Isla Desecheo in Puerto Rico. The dashed lines signify years in which no data were collected.

DOI: 10.7287/peerj.preprints.2898v1/supp-2

Figure 3

(a) Negative correlation between coral cover loss (%) and attenuation coefficient (Kd490) during 2006 and 2008 and (b) positive correlation between coral cover recovery (%) and light attenuation coefficient (Kd490) from 2009 and 2012 at reef stations in Guánica, Mayagüez (10m), Ponce, and Isla Desecheo (15m).

DOI: 10.7287/peerj.preprints.2898v1/supp-3

Figure 4

Multidimensional scaling (MDS) plots showing variations in coral assemblages between monitoring surveys at a) Mayagüez, b) Rincón, c) Guánica, d) Isla Desecheo and e) Ponce. Given the lack of interaction between year and depth, depths were pooled for visualization purposes. Due to the low sampling of years, data from Isla de Mona, Isla de Vieques, and Cabo Rojo were excluded from the MDS. Graphs display distance of centroids with year as the grouping factor.

Figure 5

Variations of mean percent cover by coral species during monitoring surveys at: a) Mayagüez 10m, b) Isla Desecheo 15m and c) 20m, and d) Isla de Mona 10m and e) 20m. Coral codes are OANN=Orbicella annularis (complex), PAST=Porites astreoides, PPOR=P. Porites, MAUR=Madracis auretenra, and CNAT=Colpophyllia natans.

Figure 6

Figure 6. Linear regression showing a positive relationship between the average chlorophyll-a and attenuation coefficient (Kd490) in the vicinity of reefs surveyed in Puerto Rico from 2000 to 2013.

DOI: 10.7287/peerj.preprints.2898v1/supp-6

Coral cover per site

Percent linear cover by scleractinian corals along transects during the different years and depths.

DOI: 10.7287/peerj.preprints.2898v1/supp-7

Orbicella annularis complex cover

Percent linear cover by Orbicella annularis complex along transects during the different years and depths.

DOI: 10.7287/peerj.preprints.2898v1/supp-8

Coral species cover

The cover of the different coral species between the reef sites in Puerto Rico. Coral species listed contributed to at least 10% of the total cover.

DOI: 10.7287/peerj.preprints.2898v1/supp-9

Table 1

Geographic coordinates, depths and monitoring years for Natural Reserve coral reef sites in Puerto Rico. Abbreviations for reef stations are listed.

DOI: 10.7287/peerj.preprints.2898v1/supp-10

Table 2

Results of the generalized additive model (GAM) to assess the relationship between coral cover loss (%) and attenuation coefficient (Kd490) during 2006 and 2008 at reef stations in Guánica, Mayagüez (10m), Ponce, and Isla Desecheo (15m). Sites were selected as random factors, while Kd490 values were fixed.

Sites were selected as random factors, while Kd490 values were fixed.
