Comparative Multi‐Marker Environmental DNA Metabarcoding of Marine Metazoan Communities: Water vs. Sediment

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT This study investigates the metazoan biodiversity in the Southern Adriatic Sea using environmental DNA (eDNA) metabarcoding. Sediment and adjacent water samples were collected from three sites (one pristine, two impacted by human activities) at three distances from the coast across two seasons.

Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

open access: yesSedimentology, Volume 73, Issue 3, Page 593-619, April 2026.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.
