Despite the diversity and oftentimes large biomass of jellyfish in marine systems, their ecological role remains poorly understood. We here provide first systematic review studies on trophic ecology Baltic Sea (a regional system under strong multiple global anthropogenic pressures). In total, we identified 57 peer-reviewed publications, with notable taxonomic bias towards two species (Aurelia a...

Blooms of invasive ctenophore Mnemiopsis leidyi can have massive consequences on fish stocks and marine food webs. The distribution, abundance diet this were investigated in the northeastern (NE) Adriatic between 2016 2019. M. was determined daily along coast Rovinj (Croatia), its spatial distribution monitored by visual census from research vessels pelagic trawl during acoustic surveys Septemb...

The Black Sea is a deep (about 2 km) elliptic basin with zonal and meridional dimensions of approximately 1000 km and approximately 400 km, respectively, located roughly between 28 ° and 42°E longitudes, 41 ° and 46°N latitudes (Figure 1). It has only a narrow opening to the shallow (<75 m deep) Bosphorus Strait; otherwise, it is a completely enclosed marginal sea. Until the early 1970s, the Bl...
