The Depositional Record, Volume 11, Issue 5, Page 1517-1541, November 2025.Bermuda patch reefs development was primarily controlled by massive coral framework construction, and variation in environmental energy, turbidity and bioerosion. These factors shaped the size, diversity and preservation of the framework, leading to a suppressed, steady vertical accretion.

Molecular Ecology, Volume 34, Issue 22, November 2025.ABSTRACT Coral species abundance and biodiversity estimates are typically based on colony macromorphology. However, such measurements often underestimate the true diversity within coral communities because morphology does not necessarily reflect behavioral or genetic divergence. We previously reported on the unusual spawning behavior of the brain coral
