Abstract
Rijeke jadranskog slijeva kratke su i izolirane, što je potaklo alopatrijsku specijaciju i rezultiralo visokom razinom endemizma. Endemske ribe roda Chondrostoma koje nastanjuju jadranski slijev su vrste Chondrostoma knerii (Heckel, 1843), u hrvatskim krajevima poznata pod nazivom podustva, i Chondrostoma phoxinus (Heckel, 1843), poznata kao podbila. Nedostatak podataka o njihovom životnom ciklusu, ekološkim nišama i nedostatak samih kriterija za određivanje rijetkosti vrsta otežava njihovu konzervaciju. Cilj je ovog istraživanja odrediti filogenetske odnose i genetsku raznolikost podustve, podbile i samog roda Chondrostoma. Uzorci tkiva trbušne peraje su korišteni za umnažanje s tri genska markera (citokrom b, beta-aktin, BMP 4) lančanom reakcijom polimeraze (PCR). Provedena je filogenetska rekonstrukcija temeljena na sekvencama navedenih markera korištenjem sljedećih metoda: metoda najveće parsimonije (MP), metoda najveće vjerojatnosti (ML) i metoda susjednog povezivanja (MJ). Dobivena filogenetska stabla i mreže potvrdili su nekadašnji bliski kontakt hrvatskih vrsta s talijanskom vrstom Chondrostoma soetta. Rodovi Achondrostoma, Iberochondrostoma i Pseudochondrostoma relativno su nedavno odvojeni od roda Chondrostoma. Niska genska raznolikost vrste C. knerii ukazuje na ugroženost ove vrste pod djelovanjem antropogenih čimbenika.
Abstract (english)
The rivers of the Adriatic Basin are short and isolated, which encouraged allopatric speciation and resulted in high degree of endemism. Endemic species of Chondrostoma genus which inhabit Adriatic Basin are species Chondrostoma knerii (Heckel, 1843), known under the name Dalmatian nase in Croatia, and Chondrostoma phoxinus (Heckel, 1843), known as Minnow nase. Lack of data about their life cycle, ecological niches and lack of criteria for determining rare species makes their conservation difficult. The aim of this study was to determine phylogenetic relationship and genetic diversity of Dalmatian nase, Minnow nase and Chondrostoma genus in general. Samples of pelvic fins tissue were used for multiplication of three genetic markers (cytochrome b, beta-actin and BMP4) using the polymerase chain reaction (PCR). Phylogenetic reconstruction was done based on sequences of aforementioned genetic markers using the methods of maximum parsimony, maximum likelihood and median joining. Resulting phylogenetic trees and networks confirmed close contact of Croatian and Italian species in the recent past. Achondrostoma, Iberochondrostoma and Pseudochondrostoma gemus were relatively recently separated from the genus Chondrostoma. Low genetic diversity of D
