East is East and West is West: Population genomics and hierarchical analyses reveal genetic structure and adaptation footprints in the keystone species Paracentrotus lividus (Echinoidea)

Diversity and Distributions: A journal of biological invasions and biodiversity, 2019
The Atlanto‐Mediterranean edible purple sea urchin, Paracentrotus lividus, is a commercially exploited keystone species in benthic communities. Its browsing activity can deeply modify the littoral landscape, and changes in its abundance are of major ...

Linking Water to the Bottom: eDNA Study of Benthic Invertebrates and Invasive Species in the Venice Lagoon

Environmental DNA, Volume 7, Issue 2, March/April 2025.
This study used environmental DNA (eDNA) metabarcoding of superficial water samples to assess benthic invertebrate biodiversity in the Venice Lagoon. Sampling from surface water revealed 80 taxonomic units, mostly benthic species, including several invasive ones, with significant spatial and seasonal variations in community composition.

Quantifying predation on benthos and its overlap with bottom fishing in the NW Atlantic

Fisheries Oceanography, Volume 34, Issue 1, January 2025.
Abstract Continental shelves experience many human pressures with demersal fisheries central to disturbing the ocean floor. However, ecological processes such as predation rates of benthos and their relationship with bottom fishing are often unknown for large marine ecosystems.
