Gradients in Primary Production Predict Trophic Strategies of Mixotrophic Corals across Spatial Scales (Current Biology)

How mixotrophic corals balance autotrophic and heterotrophic nutrition in relation to food availability is unknown. Fox et al. demonstrate that satellite estimates of nearshore primary production predict the trophic ecology of reef-building corals at regional and global scales. In more productive regions, some corals are consistently more heterotrophic.
