Best practices for generating and analyzing 16S rRNA amplicon data to track coral microbiome dynamics Open
Over the past two decades, researchers have searched for methods to better understand the relationship between coral hosts and their microbiomes. Data on how coral-associated bacteria are involved in their host’s responses to stressors tha…
