Additional file 1: Figure S1. Dynamics of holobiont reflectance (R H ). Panels a–f are aligned into columns defined by light (broken line in a) and temperature (dotted line in a) conditions (described in Figure S1). Response of an exemplar low- $$ \mu ^{\prime}_{{S,m}} $$ μ S , m ′ coral (S. pistillata) through (b) time series photos of explants, (c) spectral RH, and (f) means (black line) and standard errors of the 10 random measurements collected to estimate R H normalized to its skeleton reflectance at 675 nm. Response of an exemplar high- $$ \mu ^{\prime}_{{S,m}} $$ μ S , m ′ coral (M. digitata) through (d) time series photos of coral explants, (e) spectral RH and (f) means (gray line) and standard errors of the 10 random measurements collected to estimate R H normalized to its skeleton reflectance at 675 nm. Spectral skeletal reflectance (R S ) in panels c and e shown to contextualize R H with the limit of R S values in the visible spectrum where photopigments have substantial absorption (e.g., 675 nm, chlorophyll a absorption peak); for wavelengths > 700 nm, the limit of R H may be greater than R S . As corals bleached and less than 10 % of symbionts remained associated with the host, R H approached the values of R S .
