- Abstract:
- The striped dolphin (Stenella coeruleoalba) is one of the most abundant cetaceans of the Mediterranean Sea, nevertheless it is classified as a vulnerable species for the Mediterranean basin, according to IUCN experts. Information about its distribution, population size, interaction with human activities, are crucial for its conservation. The Gulf of Corinth is a Protected Area that belongs to the European Network Natura 2000, and that is classified as an Important Marine Mammal Area, for the presence in its waters of the following species of cetaceans: striped dolphin (Stenella coeruleoalba), common dolphin (Delphinus delphis), bottlenose dolphin (Tursiops truncatus). Striped dolphin is the most abundant species of the Gulf. It may be sighted in single species group or in mixed group with common dolphin and/or Risso s dolphins. Investigating striped dolphin distribution within the Gulf of Corinth it is crucial for the conservation of this protected species in this Protected Area. During the summers of the years from 2009 to 2017, 168 surveys were carried out for monitoring striped dolphins presence and distribution. 194 sightings of striped dolphins were realised. In order to investigate the distribution of striped dolphin within the Gulf of Corinth three different approaches have been employed: Species Distribution Model, Extent of Occurrence, Area of Occupancy. A Species Distribution Model was developed by employing Maxent. The Extent of Occurrence and the Area of Occupancy of the species were identified with QGIS. A comparison between the area highlighted with the three different geographical approaches was then carried out. This study shows that Extent of Occurrence and Area of Occupancy are useful tools that could be integrated with the results of a Species Distribution Model for a better conservation of a species within an investigated area.
