A new paper about the possible relationship between global warming and cetaceans is now available. Tethys researcher Arianna Azzellino, together with other colleagues, published "Biological consequences of global warming: does sea surface temperature affect cetacean distribution in the western Ligurian Sea?".
The work focuses on three cetacean species - striped dolphin, fin whale and sperm whale and is based on research done between 1996 and 2000 in a study area of 20,000 Km2.
The authors conclude that in the western Ligurian Sea sea surface temperature represents a key factor for the habitat selection by these three cetacean species and recommend further investigation to assess how global climate change may affect the structure of cetacean communities living in this area.
