Dashed squares indicate the sampling sites and the in-text acronym is given in parentheses. Colours correlate with subsequent figures. Image modified from Nasa’s Landsat ETM+.
Table 1.
Life history traits used to characterise a species’ function including weight (in parentheses), definition and values.
Fig 2.
Biplot of A) first and second PCs of principal coordinate analysis conducted on fish species and traits and B) Vectors identifying traits. These axes were then used to calculate SESFRic. The fifteen most abundant species have been labelled and are: Chromis margaritifer (ChMa), Chrysiptera rollandi (ChRo), Cirrhilabrus cyanopleura (CiCy), C. ryukyuensis (CiRy), Halichoeres leucurus (HaLe), H. melanurus (HaMe), Neopomacentrus filamentosus (NeFi), Odonus niger (OdNi), Pomacentrus adelus (PoAd), P. alexanderae (PoAl), P. aurifrons (PoAu), P. burroughi (PoBu), P. lepidogenys (PoLe), P. moluccensis (PoMo), Scarus flavipectoralis (ScFl). B) Vectors identifying traits (see Table 1 for trait labels) that discriminate species along PCoA axes in plot A.
Fig 3.
Mean index-environment relationship.
The dashed line at 0 of the index represents the value expected under random community assembly, while mean values (±SE) above or below indicate a deviation from the expected as calculated by the standard effect size (SES). Colours represent sampling sites and correlate with Fig 1: red = SA, green = BL, yellow = BO, blue = BA, white = LU, pink = KA, and black = KP.
Table 2.
CWM trait-environment relationships.
The table lists significant results of linear regression of individual transect-level CWM of the examined traits against three environmental parameters (rugosity, coral cover and distance from mainland).
Fig 4.
Variability (standard deviation, SD) in the standard effect size of FRic (SESFRic) and RaoQ (SESRaoQ) as a function of significant environmental covariates.
The GAM for SESFRic indicated significant relationship with A) rugosity and B) distance from shore and a GLM indicated that C) coral cover was significantly related with SESRaoQ. Plots include the expected (solid line) and ±95% confidence intervals (dashed lines). Colours represent sampling sites and correlate with Fig 1: red = SA, green = BL, yellow = BO, blue = BA, white = LU, pink = KA, and black = KP.
