Re: [MARMAM] New publication on stomach contents of stranded Ziphius cavirostris in the eastern Mediterranean
Dear All, Apologies for cross posting. We would like to inform you that the new paper on "Stomach Contents of Stranded Goose-Beaked Whales in the Levantine Basin and Aegean Sea" has been published in Marine Mammal Science. Tonay, A.M., Salman, A., Taşkaya, İ., Danyer, E., Dede, A., Çanakcı, T., Amaha Öztürk, A. 2025. Stomach contents of stranded goose-beaked whales in the Levantine Basin and Aegean Sea. Marine Mammal Science 0:e70075. You can view the article at: https://doi.org/10.1111/mms.70075 Abstract Goose-beaked whale (Ziphius cavirostris), a cosmopolitan odontocete, is commonly found in the Mediterranean Sea. This study, the first to examine the stomach contents of the goose-beaked whale in the Aegean Sea and Levantine Basin, reveals key aspects of its diet. The stomach contents of one whale from Seferihisar, Türkiye, in 2016, and five from a mass stranding on Cyprus in February 2023 were analyzed. A total of 1,448 lower beaks from 16 cephalopod species were identified, with six species-Octopoteuthis sicula, Ancistrocheirus lesueurii, Histioteuthis reversa, Chtenopteryx sicula, Chiroteuthis veranii, and Todarodes sagittatus-comprising the primary diet. Four species-Loligo forbesii, Pyroteuthis margaritifera, Pterygioteuthis giardi, and Brachioteuthis riisei-were recorded for the first time in goose-beaked whale stomachs. Their prey preference is generally pelagic cephalopods, though benthic or demersal species are occasionally eaten. The high species diversity and the presence of species not found in other studies may be due to differences in cephalopod fauna characterized by seabed and other oceanographic features of the eastern Mediterranean. The Mediterranean population is genetically divided into western and eastern subpopulations, and their diets appear to differ.

Dear All, Apologies for cross posting. We would like to inform you that the new paper on acoustic detection of small cetaceans in the northern Aegean Sea has been published in J. Black Sea/Mediterranean Environment. Dede, A., Tonay, A.M., Amaha Öztürk, A. 2025. The acoustic detection of small cetaceans in Saros Bay in the northern Aegean Sea. J. Black Sea/Mediterranean Environment 31(3): 260-268. You can view and download the article at: https://blackmeditjournal.org/the-acoustic-detection-of-small-cetaceans-in-s aros-bay-in-the-northern-aegean-sea/ Abstract A passive acoustic monitoring study using F-POD was conducted for the first time in Saros Bay in the northern Aegean Sea. Between November 2022 and January 2023, harbour porpoise (Phocoena phocoena relicta) and delphinids were detected acoustically during both day and nighttime. However, diel patterns of delphinids and porpoises did not overlap. In general, the hours of high delphinid detection coincided with lower porpoise detection, implying the temporal difference in habitat use of these taxa. A year-long or longer study should be carried out to determine whether the presence of harbour porpoise in the region is continuous or seasonal.
