Cetaceans in the Mediterranean Sea: Encounter Rate, Dominant Species, and Diversity Hotspots
We investigated the presence and diversity of cetaceans in the Mediterranean Sea, analysing the data collected by 32 different research units, over a period of 15 years (2004–2018), and shared on the common web-GIS platform named Intercet. We used the encounter rate, the species prevalence, and the...
