Microspatial variability in community structure and photophysiology of calcified macroalgal microbiomes revealed by coupling of hyperspectral and high-resolution fluorescence imaging.

On the lower shore the epiphyte community was dominated by diatoms with highly significant correlations between the hyperspectral measurement of relative abundance of diatoms (fucoxanthin, δδ 546 nm; Fig. 1b ) and pigment data for Chl c (r = 0.96, p < 0.01; Fig. 1c ), fucoxanthin (r = 0.98, p < 0.01; Fig. 1d ) and diadinoxanthin (r = 0.95, p < 0.01; Fig. 1e ).
