Evidence

Peer-reviewed

Geography

Laboratory Aiptasia model sea anemone

System

Cnidarian photosymbiosis and microbial nitrogen assimilation

## WHAT THE EVIDENCE SAYS

A November 2 study used laser microdissection, microbial transcriptomics, bacteria-controlled hosts and isotope tracing to show that algal partners were associated with altered microbiome distribution and nitrogen-assimilation pathways between anemone tissues.

## WHY IT MATTERS / OUR READ

A reef organism's microbiome may be functionally organized across tissues rather than acting as one generic microbial community.

## CAVEATS / UNCERTAINTY

Aiptasia lacks the skeleton of reef-building corals; this is mechanistic laboratory evidence, not a demonstrated reef resilience outcome.
