Mass-independent grazing rates for (a) C. rodgersii and (b) H. erythrogramma through time, where open-circles represent raw residuals from rate-mass regression and solid points shows the mean (± se) value for each time point. Panels (c) and (d) show gonad (solid line) and gut indices (dashed line) for C. rodgersii and H. erythrogramma respectively (mean ± SE). (e) Percentage nitrogen content (solid line and solid points) and C:N ratio (mol:mol; dashed line and hollow points) of E. radiata through time and (f) temperature as recorded at 3-7 m depths by in-situ loggers deployed over duration of grazing assays (grey points; mean ± SE) and daily averages from satellite SST (black line).
