From: Dangerous demographics in post-bleach corals reveal boom-bust versus protracted declines
(a) Relative area of live tissue on massive Porites colonies over 60 months. Each line represents a single colony, with line colors representing the proportion of bleaching in each colony (during the 2016 bleaching event). The red dotted line represents the average increase of 21% in colony area of massive Porites. (b) Effect of the proportional bleached area (in April-2016) on the subsequent relative change in live tissue area of massive Porites. Line and band show the prediction and 95% confidence intervals of a Gamma GLMM, while dots show raw data points. Modelling was performed in the software R34, using the glmmTMB package35. The solid horizontal line and arrows indicate where colonies effectively increased or decreased live tissue area. The dotted vertical line represents the minimum bleached area required, on average, to trigger tissue loss. mR2 = marginal R2 and cR2 = conditional R2.
