Detailed information of reef sites.
Location names, coordinates, and site characteristics of surveyed sites. S&G, spur-and-groove.
Summary of the glmmADMB results.
Lionfish abundance (ind. 100 m-2) on grouper biomass (g 100 m-2), predators, and other co-factors.
Location of survey sites.
For site abbreviations, surveys dates and coordinates refer to Table S1
Moran’s I similarity spline correlograms for lionfish and grouper raw data across all sites (top two panels) and for the glmmADMB model residuals (bottom panel).
Note the strong spatial autocorrelation of the raw data (i.e., swirling lines around zero) and how the hierarchical structure of the random effects (sites nested in regions) of the full glmmADMB model eliminated this correlation in the model residuals. A Mantel test of the model Pearson residuals (r = 0.073) corroborates the lack of spatial correlation of the residuals. Lines are the mean ± 95% confidence interval.
