Dear Marmam and ECS members.
(sorry for cross-postings!)
I am pleased to share with you a new publication in "BioInvasions
Records" regarding a Lessepsian dolphin species:
*Frantzis A. 2018. A long and deep step in range expansion of an alien
marine mammal in the Mediterranean: First record of the Indian Ocean
humpback dolphin /Sousa plumbea/ (G. Cuvier, 1829) in the Greek Seas.
/BioInvasion Records/ 7(1): 83–87.
On 7 November 2017 a solitary Indian Ocean humpback dolphin, /Sousa
plumbea/ (G. Cuvier, 1829), was sighted in Karavolas Bay, near the port
of Heraklion, Crete, Greece. On 14, 16 and 17 November 2017 another
humpback dolphin sighting, likely the same individual, was recorded 100
km further west in Souda Bay, Crete. North Crete is the third area where
this Lessepsian species was sighted in the Mediterranean Sea after
records in Israel in 2001 and in SE Turkey in 2016. To reach the north
coast of Crete, the dolphin crossed deep offshore waters that are
theoretically incompatible with its typical coastal and shallow habitat.
The distance travelled by this dolphin (1000–2330 km depending on the
path followed) is the largest movement recorded for this species. Our
observations show the potential of humpback dolphins to reach the
shallow and coastal waters of the Cyclades in the Aegean Sea, where
native populations of the vulnerable common bottlenose dolphin
(/Tursiops truncatus/) and the endangered short-beaked common dolphin
(/Delphinus delphis/) occur.
This is an *Open Access* paper, which is *freely available online* here:
