The coral microbiome is a critical component of coral health and resilience, yet it is unclear what factors drive coral microbiome composition, especially within the context of coral bleaching. Here, we use whole genome sequencing data combined with a machine learning approach (RDAforest) to assess predictors of the microbiome in 208 colonies of Acropora millepora from 12 reef sites in the Central Great Barrier Reef during a 2016 bleaching event. We characterized microbiome variation using k-mers. While some environmental variables, such as chlorophyll seasonal range and maximum degree heating weeks, were associated with microbiome composition, we find that host genetics and dominant photosymbionts were more powerful predictors. In contrast, bleaching score had negligible predictive power. The corals microbiome therefore correlates with dominant photosymbiont identity even during a bleaching event. The association of the microbiome with the environment suggests that the coral microbiome can serve as a proxy for environmental variation when environment cannot be measured directly, which may be especially useful in ancient DNA studies.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
