Figure 1. a) Total MaxN of all species identified in individual BRUVs videos and b) number of species identified from 2002-2018 (data not available from 2012; 2016; 2017). Green (a) and purple (b) lines are predicted values from the respective linear mixed models (N = 213).
Figure 2: Estimated probability of occurrence (mean +/- S.E., n=50) for marine fishes associated with a) tropical and b) temperate systems categorised by tropic group (piscivores, herbivores, invertivores and planktivores) from 2002-2018 for mid-shelf reefs in SIMP where total kelp decline was observed.
Figure 3: Change in probability of occurrence for species whose probability of occurrence changed significantly; either increasing (positive slope) or decreasing (negative slope) over the study period. Red symbols indicate tropical associated species and blue symbols indicate temperate associated species.
Figure 4 : Geometric morphometrics model for fin-fish species identified using BRUV surveys on tropicalised reefs. Numbers are species identity as outlined in Supplementary Table 2 and colours represent ecoregion, temperate (blue) or tropical (red). Position of number represents the position of each species relative to the group and surrounding segment represents the Voronoi polygon that species. RELW axes 1 and 2 represent 52% of body shape variability across the community.
Figure 5 : Relationship between change in probability of occurrence and a) modelled Voronoi area and b) distance from the community weighted mean of fish species associated with temperate (blue symbols) or tropical ecoregion (red symbols) for each trophic guild (Piscivore, Herbivore, Invertivore, Planktivore).
