Molecular systematics of the Atlanto-Mediterranean Solea species
No full textWithin the genus Solea, four sister lineages have been evolved that actually correspond to the species S. vulgaris, S. senegalensis, S. kleini and S. lascaris. The existence of S. aegyptiaca and S. impar is not supported and these species can be synonymized under S. vulgaris and S. lascaris, respectively. This pattern of taxonomy agrees fully with that proposed by Ben-Tuvia (1990; Journal of Fish Biology 36, 947-960) based on morphological features. In addition, mtDNA data contradict the widely accepted relatedness between S. kleini and S. lascaris based on the shared enlarged forenostril on the blind side. A sample of soles clearly related to S. senegalensis was caught in the Gulf of Taranto (Ionian Sea), representing the most western finding of this species in the Mediterranean Sea.

No full textRecent state of demersal resources in the Adriatic Sea
No full textA picture of the recent situation and changes in demersal resources of the Adriatic Sea (GSA 17) is reported on the basis of the long –term monitoring of demersal communities performed in the framework of the international trawl survey MEDITS (1996-2010). GIS maps of distribution of 78 species are also reported
Time series ad biology of Trisopterus minutus capelanus (Lacepede, 1800) in the North and Central Adriatic Sea
No full textThe paper examines data of 40 trawl surveys carried out in the North and Central Adriatic Sea from 1982 to 2004 to describe the distribution area, the abundance and some details of the biology of Trisoterus minutus capelanus (Osteichthyes, Gadidae). Their trends during time are also analyse
Temporal and spatial distribution of some elasmobranchs in the Northern and Central Adriatic Sea
No full textData collected from trawl survey, carried out in the Northern and Central Adriatic Sea, were analysed in order to know about the spatial distribution of Myliobatis aquila, Mustelus mustelus and Squalus acanthias. Distribution areas with relation to different seasons were discussed
Tsunami survey expedition: preliminary investigation of Maldivian coral reefs two weeks after the event.
No full textAbstract On December 26th 2004, a earthquake west of Sumatra generated a devastating tsunami. Hundreds of thousands of people fell victim. Economic losses were greatest in those countries dependant on tourism. The impact in the Maldives on persons and things was modest. Immediately following the event and notwithstanding the lack of scientific data, the mass media gave catastrophic reports on the state of coral reefs in the area. This paper reports on the first survey on coral reefs in the Maldives after the Tsunami. Ocean walls, passes, inner reefs, and shoals in the North and South Malé atolls, were surveyed two weeks after the event. Significant damage was recorded in the passes in the South Malé atoll. Our observations showed that the damage was more or less extensive depending on latitude and topography. Sri Lanka may have broken the wave’s rush, reducing the extent of the impact on northern atolls. The water’s acceleration inside the passes was so intense as to cause reef collapses. The observed damage represents a minimum fraction of the entire coral reef system. Tourist perception of the area seems unchanged. These data may be used to disseminate correct information about the state of Maldives coral reefs, which would be useful in relaunching local econom
Nursery areas of some demersal species in the Adriatic Sea (GSA 17): prospects of management
No full textPrediction of nursery areas localization of some demersal species was studied in Northern and Central Adriatic Sea using geostatistical tools and data from trawl surveys time series. The investigated species are: Eledone cirrhosa (Cephalopoda, Octopodidae), Lophius budegassa (Teleostei, Lophiidae), Merluccius merluccius (Teleostei, Merlucciidae) and Nephrops norvegicus (Crustacea, Nephropidae). Protection of these areas through limitation of fishing pressure is discussed
