Environmental DNA, Volume 7, Issue 5, September–October 2025.Our study used benthic eDNA metabarcoding to assess metazoan biodiversity, community structure, and network stability in shallow and deep artificial reefs across seasons. Results revealed distinct spatial and seasonal patterns in diversity and co‐occurrence networks, with environmental factors like temperature, nitrite, and DO driving community ...
