Novi nalazi kritično ugroženog sklata sivca Squatina squatina(Linnaeus, 1758) s otoka Korzike, Francuska
Angel Sharks are among the most threatened families of fish in the world. In the Mediterranean three species are present facing a severe depletion with several local extinction events as a result of overexploitation by fisheries. Hereby, we present 7 additional records of Squatina squatina from Corsica contributing to the new regional action plan for Angel Sharks in the Mediterranean Sea. Most records include juvenile specimens, indicating that the area might be a nursery ground for the species.Sklat sivac pripada najugroženijoj obitelji riba na svijetu. U Sredozemlju su prisutne tri vrste koje su suočene s velikim iscrpljivanjem i s nekoliko lokalnih slučajeva izumiranja kao posljedice prekomjerne eksploatacije u ribolovu.Utvrđeno je u ovom radu 7 dodatnih nalaza sivca sklata Squatina squatina s Korzike koji doprinose novom regionalnom akcijskom planu za očuvanje sklatova u Sredozemnom moru. Većina nalaza uključuje juvenilne primjerke, što ukazuje da bi područje moglo biti hranilište i obitavalište vrste
Filling the gap : a new record of diamondback puffer (Lagocephalus guentheri Miranda Riberio, 1915) from the west-eastern Mediterranean Sea, Turkey
One specimen of the diamondback puffer, Lagocephalus guentheri (Miranda Riberio, 1915), was recorded along the Turkish coast, off Gökova Bay, through the angling method on 12 June 2017. The morphological features of this species were examined indirectly by image analyses software. This finding also supports the documented occurrence of the diamondback puffer fish along Turkish coasts.peer-reviewe
Paraneoplastic hypoglycaemia secondary to IGF-2 secretion from a metastatic gastrointestinal stromal tumour
We report the case of a 79-year-old male with previous history of non-Hodgkin's lymphoma in remission, who presented acutely to the Accident and Emergency department with recurrent episodes of hypoglycaemia. At the time of presentation, a random glucose was low at 1.4 mmol/l, which upon correction resolved his symptoms. In hindsight, the patient recalled having had similar episodes periodically over the past 2 months to which he did not give much notice. While hospitalized, he continued having episodes of symptomatic hypoglycaemia, requiring treatment with intravenous dextrose and per os steroids. Once stable, he was discharged on oral prednisolone and dietary advice. A computed tomography scan performed during inpatient stay showed multiple deposits in the abdomen. An ultrasound guided biopsy of one of the liver deposits was performed. Immunohistochemistry supported the diagnosis of a gastrointestinal stromal tumour (GIST) positive for CD34 and CD117. The diagnosis of non-islet cell tumour hypoglycaemia (NICTH) secondary to an IGF2 secreting GIST was confirmed with further biochemical investigations (IGF2=105.9 nmol/l; IGF2:IGF1 ratio 23, Upper Level of Normal (ULN) <10). Targeted cytoreductive treatment with Imatinib mesylate following assessment of the tumour's mutational status was successful in preventing hypoglycaemia over a 21-month follow-up observation period
First record of the Atlantic spadefish Chaetodipterus faber (Broussonet, 1782) in the Mediterranean Sea: is it a new aquarium release?
Prvi potvrđeni zapis o vrsti Pomatoschistus microps(Krøyer,1838) (Pisus: Gobiidae) iz Jonskog mora s bilješkama o staništu i rasprostranjenosti
Two specimens of the common goby (Pomatoschistus microps) were observed in the estuarine environment of the River Asinaro (Sicily). These records represent the easternmost and southernmost observations of the species in the Mediterranean Sea, and the first confirmed record in the Ionian Sea (central Mediterranean Sea). We also provide notes about its habitat and current distribution in the Mediterranean Sea.Dvije jedinke vrste Pomatoschistus microps zabilježene su u okolišu ušća rijeke Asinaro (Sicilija).Ovaj nalaz predstavlja najistočniji i najjužniji nalaz vrste u Sredozemnom moru i prvi potvrđeni nalaz u Jonskom moru. Također se navodi njegovo stanište kao i trenutna rasprostranjenost u Sre-dozemnom moru
How accurately are we describing the longline bycatch? The case of the ‘rare’ shark Alopias superciliosus in eastern Mediterranean
Filling the Gap of DataLimited Fish Species in the Eastern Mediterranean Sea: A Contribution by Citizen Science
: The biodiversity of the Mediterranean Sea is rapidly changing due to anthropogenic activity and the recent increase of seawater temperature. Citizen science is escalating as an important contributor in the inventory of rare and datalimited species. In this study, we present several records of five datalimited native fish species from the eastern Mediterranean Sea: Alectis alexandrina (Geoffroy SaintHilaire, 1817), Ranzania laevis (Pennant, 1776), Dalatias licha (Bonnaterre, 1788), Lophotus lacepede (Giorna, 1809), and Sudis hyalina (Rafinesque, 1810). All of the records were collected by a participatory process involving fishers and validated by associated taxonomic experts of the citizen science programme “Is it Alien to you? Share it!!!”. This study fills an important gap for the distribution of the reported species and signifies the important role of citizen participation as a tool for extending marine biodiversity knowledge and fisheries management in an area with several gaps of knowledge on targeted and nontargeted species.</jats:p
