Pep Coll, one of the best-known and most influential marine biologists in the Balearic Islands, has died in Palma after an illness, and his passing has left a strong impact on the conservation and marine sector. Pep Coll's death leaves behind a career dedicated to the knowledge of the Balearic Islands' marine ecosystems and, especially, to the study of marine reserves, fisheries management, and the mechanisms that allow biodiversity to recover when a marine area is properly protected.
