Abstract
Foto-identifikacija dobrog dupina (Tursiops truncatus Montagu, 1821), temelji se na uočavanju prirodnih oznaka na leđnoj peraji koje joj daju prepoznatljiv obris te se zbog toga nazivaju primarnim oznakama. Tijekom vremena dolazi do promjene izgleda leđne peraje, zbog zadobivanja novih oznaka, što može rezultirati krivom identifikacijom, a time i greškama u analizama temeljenim na foto-identifikacijskim podatcima. Ovim istraživanjem kategorizirani su tipovi primarnih oznaka, utvrđena je vremenska dinamika promjena oznaka te razlike među spolovima. Uz primarne oznake, promatrane su i sekundarne oznake kako bi se utvrdila njihova dugovječnost i mogućnost primjene u identifikaciji. Korištenjem dodatnih značajki, uz primarne oznake, povećava se točnost metode foto-identifikacije i analiza temeljenoj na toj metodi, a osobito su važni kod slabo označenih jedinki i mladunaca. Istraživanje se provelo na podacima Instituta Plavi Svijet, prikupljenim u sjevernom i srednjem Jadranu, u razdoblju od 2005.-2015. godine.
Abstract (english)
Photo-identification of common bottlenose dolphin (Tursiops truncatus Montagu, 1821) is based on natural marks on a dorsal fin, which makes a dorsal fin recognizable hence those marks are called primary natural marks. Over the lifetime, dorsal fin shape changes because of the new marks, what can lead to wrong identification and thus alter the results of the analyses based on photo-identification data. We named and categorised types of primary marks, examine the dynamics of changing the marks and sex difference in changes. In addition to primary marks, we examine secondary marks in aim of clarifying the longevity and possibility of their use for photo-identification. Combination of primary marks and different other motives increase the accuracy of photo-identification and analyses based on its data, and it is especially important for poorly marked individuals and calves. This research was done on Blue World Institute data, collected in Northern and Central Adriatic Sea, between 2005. and 2015.
