There were 293 variable and 74 conservative nucleotides, 279 of which were parsimony informative over 367 bp sequences of the mtDNA Cyt b region. Overall mean genetic diversity was 0.433, with the smallest genetic distance (0.2384) observed between M. mustelus and S. canicula, and the largest (1.3040) between G. melastomus and I. oxyrinchus. All species were clearly separated in NJ and MP trees, exhibiting high bootstrap values, and the observed genetic divergence clearly discriminated among all the shark species examined. Additionally, the study identified low genetic diversity and the presence of regional haplotypes, which suggests the need for immediate conservation strategies that are tailored specifically to these ecologically important predatory shark species.20242026-07-06 09:43:47Delo ni kategorizirano30802slImetniki avtorskih pravic na prispevkih so avtorji.
