The bastard grunt Pomadasys incisus (Bowdich, 1825), an Atlantic teleost, has recently been recorded at multiple sites along the French Ligurian Sea. Three juveniles were captured in Villepey Lagoon, while several groups of sub‐adult and adult individuals were observed at Cagnes‐sur‐Mer and Monaco between 2020 and 2024. These records indicate a shift from occasional sightings to a perennial presence, likely linked to ongoing M...

These became more significant, transforming and even disruptive since the 19th century when the channel connecting the lagoon to the sea was deepened and the surrounding areas were industrialized and urbanized. Pollution and anoxic crises were major consequences. Concomitantly, many non-indigenous species (NIS) arrived in the la...

Introduction Coastal detrital bottoms (CDB) are one of the most extensive habitats of the continental shelf worldwide, in the upper levels of the circalittoral zone. Hosting a diverse community structured by sediment grain size, trophic interactions and calcified organisms, CDB exhibit important ecological functions. In the Mediterranean Sea, CDB are constituted by recent elements partly provided by adjacent infralittoral and...

The population of Scorpaenidae was investigated in the Nature Reserve of Scàndula (Corsica, France, NW Mediterranean). While absent from Corsica a few decades ago, the Madeira rockfish Scorpaena maderensis is now the most abundant scorpaenid species in shallow rocky reef areas, far outnumbering Scorpaena notata and Scorpaena porcus . Considered as a subtropical species of Atlantic origin, the northward progression of the therm...
