The Middle Eastern Biodiversity Network: Generating and sharing knowledge for ecosystem management and conservation

Despite prevailing arid conditions, the diversity of terrestrial and freshwater biota in the Middle East is amazingly high and marine biodiversity is among the highest on Earth. Th roughout the Region, threats to the environment are moderate to severe. Despite the outstanding economic and ecological importance of biological diversity, the capacity in biodiversity-related research and academic education is inadequate. The "Middle Eastern Biodiversity Network" (MEBN), founded in 2006 by six universities and research institutes in Iran, Jordan, Germany, Lebanon and Yemen was designed to fi ll this gap. An integrated approach is taken to upgrade biodiversity research and education in order to improve regional ecosystem conservation and management capacities. A wide range of activities are carried out in the framework of the Network, including capacity building in biological collection management and professional natural history curatorship, developing university curricula in biodiversity, conducting scientifi c research, organising workshops and conferences on Middle Eastern biodiversity, and translating the results of biodiversity research into conservation and sustainable development.

The Presence of the invasive Lionfish Pterois miles in the Mediterranean Sea

Here we report the occurrence of Pterois miles in the Mediterranean Sea, based on the capture of two specimens along the coast of Lebanon. Previously, only one record of the species from the Mediterranean Sea had been documented. The new records highlight the arrival of new propagules of P. miles, more than two decades later, hinting to a future potential invasion of the Mediterranean Sea

Društvene mreže omogućuju rano otkrivanje nezavičajnih vrsta: prvi nalaz crvene hame Sciaenops ocellatus (Actinopterygii: Perciformes: Sciaenidae) u talijanskim vodama

The red drum Sciaenops ocellatus is a large demersal fish that represents one of the top predators in estuarine environments of its native range. This species is commonly reared in aquaculture facilities, and it has already been reported as non indigenous from several countries. Here we report its first sighting in Italian waters, as well as the second documented occurrence for the Mediterranean Sea. The individual was landed in southern Sicily by artisanal fishery and this unusual observation was immediately shared on Facebook. The importance of considering social networks as tools for NIS detection is briefly discussed in light of the recognized difficulties to properly track biological introductions in the marine environment.Crvena hama, Sciaenops ocellatus, je velika demersalna riba, koja je jedna od najvećih grabežljivaca u estuarijskim okruženjima njezinog prirodnog areala rasprostranjenja. Ova vrsta se obično uzgaja u akvakulturi, a već je zabilježena kao nezavičajna u nekoliko zemalja. U ovom radu utvrđeno je prvo viđenje ove vrste u talijanskim vodama, koje je ujedno druga dokumentirana pojava u Sredozemnom moru. Primjerak je ulovljen tijekom priobalnog ribolova u južnoj Siciliji. Ova neuobičajena pojava je odmah podijeljena na društvenoj mreži (Facebook). Važnost razmatranja društvenih mreža kao alata za otkrivanje nezavičajnih vrsta kratko je raspravljan u svjetlu prepoznatih poteškoća kako bi se pravilno pratili biološki unosi u morski okoliš

New records of the silver-cheeked toadfish Lagocephalus sceleratus (Gmelin, 1789) in the Tyrrhenian and Ionian Seas: early detection and participatory monitoring in practice

5 pages, 3 figuresThe silver-cheeked toadfish Lagocephalus sceleratus (Gmelin, 1789)—an invasive toxic species well established in the eastern Mediterranean—is rapidly expanding through the western Basin and a public campaign was set to inform Italian citizens on the risks associated with its consumption. Both news media and local communities responded rapidly to the initiative generating an increasing flow of information. On 15 April 2016, a new capture of this species (off Briatico, Calabria, Italy at 25 m of depth), was promptly reported to the authors, representing the first documented record of L. sceleratus from the Tyrrhenian Sea. On 7 June 2016, a second specimen was captured at Montebello Ionico in Calabria. This case of early detection is here presented as a successful example of interplay among citizens, researchers, and policy makers: a powerful approach for monitoring the spread of invasive species and reducing their potential impacts through increasing awarenessPeer Reviewe

New alien mediterranean biodiversity records (March 2020)

The current article presents 18 new records from seven Mediterranean countries. These records include one rhodophyte, four nudibranchs, two crustaceans, one stingray and 10 bony fishes. They are grouped by country as follows: Lebanon - first record of the Striped bass Morone saxatilis, the stingray Himantura leoparda, the Areolate grouper Epinephelusareolatusand theSpot-fin porcupinefish Diodon hystrix from various parts of the country; Turkey - first record of the invasive red alga Grateloupia turuturufrom the sea of Marmara (region of Bandırma), the sea slug Goniobranchus obsoletus and the crab Arcania brevifrons from the Gulf of Antalya and the cladoceran Pleopis schmackeri from several locations along the Aegean Sea; Cyprus - first record of the alien sea slug Berthellina citrina from the region of Cape Greco and an observation of a butterflyfishHeniochussp. from the north-eastern side of the island; Greece - first record of the alien sea slug Anteaeolidiella lurana from the region of Heraklion in Crete and the record of the Atlantic spadefish Chaetodipterus faber and the Black surgeonfish Acanthurus cfr gahhmfrom Salamina Island; Slovenia - first record of the alien sea slug Thecacera pennigera from Izola; Italy - first record of the hybrid Striped bass (Morone saxatilis × Morone chrysops) from the northern Tyrrhenian Sea and a first record of the goldfish Carassius auratus from the region of Apulia; Libya - first record of the Red Sea goatfish Parupeneus forsskali and the African surgeonfish Acanthurus monroviae, respectively from the eastern (Al-Tamimi area) and the western shore (Al-Khums area).University Research Board of the American University of Beirut.

A lionfish (Pterois miles) invasion has begun in the Mediterranean Sea

Until now, few sightings of the alien lionfish Pterois miles have been reported in the Mediterranean and it was questionable whether the species could invade this region like it has in the western Atlantic. Here, we present evidence from divers and fishermen that lionfish have recently increased in abundance and within a year colonised almost the entire south eastern coast of Cyprus, likely due to sea surface warming. At least 23 different fish are reported of which 6 were removed. Groups of lionfish exhibiting mating behaviour have been noted for the first time in the Mediterranean. Managers need this information and should alert stakeholders to the potential ecological and socio-economic impacts that may arise from a lionfish invasion. Actions could involve incentives to engage divers and fishermen in lionfish removal programmes, as these have worked well at shallow depths in the Caribbean. Given that the Suez Canal has recently been widened and deepened, measures will need to be put in place to help prevent further invasion

Genetics reveal the identity and origin of the lionfish invasion in the Mediterranean Sea

Following aquarium releases, invasive lionfishes have colonized large areas of the Caribbean and western Atlantic, resulting in an immense ecological damage. The early stages of that invasion are poorly known. Indeed, a lag of time between the introduction and detection often preclude genetic characterization of that crucial phase. With elevated awareness, the recent invasion of Pterois miles was quickly detected in the Mediterranean Sea. We hereby show that the very first individuals establishing populations in the Mediterranean Sea display haplotypes that nest within the large genetic diversity of Red Sea individuals, thus indicating an invasion via the Suez Canal. We also show that only two haplotypes are detected in the Mediterranean Sea, suggesting that few individuals may have been involved in the invasion. Thus, we conclude that the Mediterranean invasion is the result of a movement of individuals from the Red Sea, rather than from other means, and that low genetic diversity does not seem to have a negative effect on the success and spread of lionfish into the Mediterranean Sea
