Over 40 years of marine amphipod data from Italian waters has been consolidated and made openly accessible, providing a crucial baseline for conservation and ecological monitoring.
A study published in Biodiversity Data Journal has synthesized over 40 years of unpublished data on marine amphipods from Italian waters, making the records openly available via the Global Biodiversity Information Facility (GBIF).
Key Details
- Researchers analyzed 4,344 previously unpublished records spanning from 1980 to 2025, identifying 302 amphipod species across the Adriatic, Tyrrhenian, and Ionian Seas.
- The Tyrrhenian Sea boasts the highest taxonomic richness with 258 species, while the Adriatic Sea has the most records due to historical sampling intensity.
- The study updates the Italian inventory of marine amphipods and underscores Italy's role as a Mediterranean biodiversity hotspot, according to coordinator Prof. Sabrina Lo Brutto of the University of Palermo.
- The dataset includes records from universities, environmental agencies, and research institutes coordinated under the National Biodiversity Future Center (NBFC).
- 11 non-indigenous species were identified, primarily in ports, lagoons (e.g., Venice Lagoon), and aquaculture facilities.
Background
Amphipods are small crustaceans that recycle nutrients, connect food webs, and serve as bioindicators for pollution and ecological changes. Prior to this study, distribution data for these species were fragmented, leading to outdated or incomplete records.
Statements
"Harmonizing datasets under FAIR principles (Findable, Accessible, Interoperable, Reusable) ensures the information is scientifically robust and openly available for future research," the study notes.
Significance
The study provides a baseline for monitoring environmental change and supports conservation efforts, such as the EU and NBFC goal to protect 30% of land and sea by 2030.
