Abstract

Dobri dupin - Tursiops truncatus (Montagu, 1821) jedini je stalni morski sisavac Jadranskog mora te se pretpostavlja da u hrvatskom dijelu živi između 220 do 250 jedinki. Korišteni su uzorci dobrih dupina uginulih u hrvatskom dijelu Jadranskog mora i dva uzorka iz talijanskog dijela Jadrana. Cilj je utvrditi kraniometrijske značajke i raznolikost sljedova dijela kontrolne regije mtDNA dobrog dupina iz Jadranskog mora. Unutar 108 jedinki postoji 11 različitih haplotipova. Najučestaliji je haplotip DD01. Genska raznolikost iznosi 0,6108, a nukleotidna 0,010452. Haplotip DD07 je jedinstven. U 96 lubanja odraslih jedinki nađeno je da se mužjaci i ženke jadranske populacije razlikuju u 19 kraniometrijskih mjera, u mužjaka je lubanja robusnija. Lubanje dupina izraelskih, crnomorskih, kineskih te istočno floridskih populacija su kraće, a u populacija iz istočnog Atlantika, Sjevernog mora, mora oko Mauritanije, mora oko Južnoafričke Republike i iz mora oko Australije znatno su dulje su od lubanja jadranskih dobrih dupina.

Abstract (english)

Bottlenose dolphin - Tursiops truncatus (Montagu, 1821) is the only resident marine mammal in the Adriatic Sea, and it is assumed that in the Croatian part live between 220-250 individuals. Carcasses of bottlenose dolphins from the Croatian part and two samples from the Italian part of the Adriatic were used. The goal is to determine craniometrical features and diversity of the mtDNA control region of bottlenose dolphins from the Adriatic Sea. Among 108 individuals, there are 11 different haplotypes. The most common haplotype is DD01. Genetic diversity was 0.6108, and nucleotide 0.010452. Haplotype DD07 is unique. Males and females of Adriatic population differ in 19 skull variables, in males the skull is more robust. Skulls of Israeli, Black Sea, Chinese and Eastern Florida populations are shorter, while skulls of populations from the Eastern Atlantic, North Sea, the seas around Mauritania, South Africa and Australia are considerably longer than the skulls of Adriatic bottlenose dolphins.
