Fig. 2: Physiological metrics positively scale with heterotrophy but do not offset bleaching effects.
From: Selective nutrient incorporation may underestimate heterotrophy of a mixotrophic reef-building coral
Physiology metrics by experimental treatment (bleached + fed 6x week−1: pink, control: green, fed 2x week−1: yellow, fed 6x week−1: blue) are plotted as points with each point representing a coral fragment with box and whisker plots added, horizontal lines in box represent median and quartiles while whiskers represent 1.5(IQR) distance from each upper and lower quartile, horizontal connecting bars between treatments indicate significance levels of post hoc pairwise contrasts: *p < 0.05, **p < 0.01, ***p < 0.001. a FA mass in host tissues normalized to surface area (B_F_6x: n = 29, control: n = 23, F_2x: n = 22, F_6x: n = 27), b FA mass in symbiont normalized to dry tissue mass (control: n = 23, F_2x: n = 21, F_6x: n = 27), (c) surface area normalized host protein (B_F_6x: n = 33, control: n =  31, F_2x: n = 27, F_6x: n = 33), d symbiont protein cell−1 (control: n = 28, F_2x: n = 24, F_6x: n = 31), e whole experiment aragonite skeleton growth (B_F_6x: n = 31, control: n = 27, F_2x: n = 25, F_6x: n = 32), f relative electron transport rate from day 15 of the experiment as a representative time point of patterns seen in photo-physiology (B_F_6x: n = 32, control: n = 29, F_2x: n = 27, F_6x: n = 33, see supplementary information for more details), g symbiont density normalized to surface area (B_F_6x: n = 33, control: n = 28, F_2x: n = 24, F_6x: n = 30), and (h) total chlorophyll concentration normalized to surface area (B_F_6x: n = 33, control: n = 31, F_2x: n = 27, F_6x: n = 33).
