Changes in availability and use of different branching corals across the four (10 × 10 m) experimental plots from day 0 (orange) to day 16 (grey). Habitat availability (A) is calculated based on the sum of estimated projected areas of live tissue for every colony of each coral taxa (species or morphotype). χ2 statistics (Pearson statistic with Yate’s correction) were used to compare the proportion of corals that were consumed by CoTS relative to occupation by damselfishes for all corals combined (χ2All) and then for P. cf. damicornis separately (χ2Pdam). Changes in habitat use for Dascyllas aruanus (B), Dascyllus reticulatus (C), and Pomacentrus moluccensis (D) are shown based on the total number of fishes recorded across all colonies of each coral taxa. Here, χ2i compares patterns of coral use by each damselfish species on day 0 with proportional availability of the different corals, and χ2ii tests for changes in patterns of habitat use between day 0 and day 16.
