marine mammals in the mediterranean sea: an overview.despite being a small part of the world's oceans, the mediterranean sea hosts a diverse marine mammal fauna, with a total of 28 different species known to occur, or to have occurred, in the region. species currently recognised as regular in the mediterranean-the mediterranean monk seal (monachus monachus) and 11 cetaceans (fin whale, balaenoptera physalus; sperm whale, physeter macrocephalus; cuvier's beaked whale, ziphius cavirostris; short-beaked common dolphin, delphinus delphis; long-finned ...201727770981
correction: the effects of marine traffic on the behaviour of black sea harbour porpoises (phocoena phocoena relicta) within the istanbul strait, turkey.[this corrects the article doi: 10.1371/journal.pone.0172970.].201728813515
the effects of marine traffic on the behaviour of black sea harbour porpoises (phocoena phocoena relicta) within the istanbul strait, turkey.marine traffic is threatening cetaceans on a local and global scale. the istanbul strait is one of the busiest waterways, with up to 2,500 vessels present daily. this is the first study to assess the magnitude of short- and long-term behavioural changes of the endangered black sea harbour porpoises (phocoena phocoena relicta) in the presence of marine vessels within the istanbul strait. markov chains were used to investigate the effect of vessel presence on the transition probability between beh ...201728296899
is there a distinct harbor porpoise subpopulation in the marmara sea?genetic population structure of geographically isolated endangered black sea harbor porpoise (phocoena phocoena relicta) is little known in turkish waters, especially in the turkish straits system (tss- marmara sea, bosphorus and dardanelles), which connects the black sea and the aegean sea. mitochondrial dna sequences of 70 new individuals sampled in the turkish black sea, tss and aegean sea, revealed five new haplotypes from the black sea. the findings support the idea that harbor porpoises fr ...201727159712
occurrence of perfluorooctane sulfonate and other perfluorinated alkylated substances in harbor porpoises from the black sea.perfluorooctane sulfonate (pfos) and other perfluorinated alkylated substances (pfas) were determined in liver, kidney, muscle, brain, and blubber samples of 31 harbor porpoises (phocoena phocoena relicta) of different age and sex stranded along the ukrainian coast of the black sea. in all individuals and in all tissues, pfos was the predominant pfas, accounting for on average 90% of the measured pfas load. pfos concentrations were the highest in liver (327+/-351 ng/g wet wt) and kidney (147 +/- ...200717265965
trace metal and stable isotope measurements (delta13c and delta15n) in the harbour porpoise phocoena phocoena relicta from the black sea.stable carbon and nitrogen isotopes (delta13c and delta15n) and trace metals (cd, zn, cu, fe, se, and hg) were analysed in the tissues of 46 harbour porpoises (phocoena phocoena relicta) caught in fishing nets along the ukrainian coasts between 1997 and 1998. mean delta13c values differed significantly between male and female harbour porpoises suggesting a trophic segregation between sexes with a more coastal distribution for females at least during their gestation and nursing periods. hepatic h ...200415234086
total and organic mercury in the black sea harbour porpoise phocoena phocoena relicta.this paper reports on mercury (hg) concentrations in different tissues (liver, muscle, kidney, blubber and brain) of harbour porpoises phocoena phocoena found dead in the black sea between 1997 and 1999, mainly bycaught in fishing nets (n = 79). total hg and organic hg (mehg) were determined. the main factor affecting hg accumulation was, as expected, age, with mehg concentration increasing with age. accumulation of high concentrations of inorganic hg in the liver was probably due to a slow deme ...200111693645
