The invasion of Indo-Pacific fish through the Suez Canal has dramatically altered the diversity of fish assemblages on the upper shelf of the southeastern Mediterranean. Yet, their role in the trophodynamics of the novel assemblages has been largely overlooked. In the present study, we investigated the impacts of the alien fish species on the struc...
Article
The number of alien species in the Mediterranean Sea is steadily increasing and it seems that the pace has been accelerating since the turn of the century (Galil et al. 2014). In 2015 alone five additional fish species have been reported, Epinephelus geoffroyi (Klunzinger, 1870) (Golani et al. 2015); Stolephorus indicus (van Hasselt, 1823) (Fricke...

Sea turtles were targeted by fisheries in the Mediterranean from 1920 to 1970 and have undergone severe exploitation. At least 30,000 to 40,000 turtles were caught along the Palestinian coastline during the 1920s to 1930s. Although intentional cap- ture of marine turtles is now illegal, sea turtles are still incidentally caught by the fishing indus...

During a deep-sea survey off the Mediterranean coast of Israel conducted on 31 July 2013 a small, but well preserved fragment of the tentacular stalk of Chiroteuthis veranii was collected at a depth of 978 m. The finding constitutes the first indication that this deep-sea cephalopod is living in the deeper parts of the southern Levantine Sea. It is...
Article
The first Red-Sea Indo-Pacific alien moray eel in the Eastern Mediterranean is reported here. A single specimen of Gymnothorax reticularis was captured by a commercial bottom-trawl vessel off the northern coast of Israel. Morphological and anatomical similarities with the single known Red-Sea specimen raise an old taxonomic dilemma.
Article
The Indo-Pacific fish species Vanderhorstia mertensi was found, for the first time, off the Israeli coast in the Mediterranean. This shrimp-associated goby was reported so far only from the Mediterranean coast of Turkey. Its presence verifies the status of V. mertensi as an Erythraean alien.
Article
The Indo West Pacific nakedband gaper, Champsodon nudivittis, is recorded for the first time from Israel on the basis of a single specimen collected off Ashdod, southern Israel.

Question
Dear all,
I'm looking for an example of a country that possesses both the source and the recipient habitat of an invasive species, except Israel and Egypt..
It may be marine, terrestrial, faunal or floral organism.
I'm mainly interested about the conservation management-actions taken by the country.
In other words, how to protect a species in one place, and cull it from the other.
Thanks in advance,
Nir Stern
