Abstract

Prema dosadašnjim istraživanjima na području jadranskog slijeva obitava sedam vrsta roda Squalius, a na lokalitetima obuhvaćenim ovim istraživanjem postoji mogućnost pronalaska četiriju vrsta ovog roda. Jedinke iz ovog istraživanja determinirane su kao vrste Sq. squalus i Sq. svallize. Istraživanje je obuhvatilo 6 rijeka i jezera: Boljunšćica, Butoniga, Ljuta, Raša, Trebišnjica i Visovac. Cilj ovog istraživanja bio je opisati morfološke karakteristike vrsta Sq. squalus i Sq. svallize s područja jadranskog slijeva Hrvatske i Bosne i Hercegovine, utvditi stupanj raznolikosti unutar pojedinih populacija i između populacija, te provjeriti upućuju li raznolikosti na prisutstvo kriptičkih taksonomskih jedinica. S ciljem utvrđivanja raznolikosti provedene su morfometrijske i merističke analize. Morfometrijske značajke analizirane su različitim statističkim metodama, a rezultati morfometrijskih i merističkih analiza uspoređeni s dostupnim literaturnim podacima. Rezultati morfometrijskih analiza ukazali su na inter- i intrapopulacijsku varijabilnost, a najzanimljivijim se pokazalo grupiranje populacija Sq. squalus iz Boljunšćice i Sq. svallize iz Ljute. Varijabilnost unutar i između populacija uočena je i kod merističkih značajki. Rezultati analiza morfometrijskih i merističkih značajki ukazuju kako postoji mogućnost genetski uvjetovane varijabilnosti što otvara potrebu za daljnim istraživanjima. Zaključno, rezultati ovog istraživanja pretstavljaju značajan doprinos poznavanju morfologije vrsta roda Squalius te će koristiti u budućim istraživanjima ovog roda.

Abstract (english)

According to present investigations Adriatic Sea basin is home for seven species of genus
Squalius, and in localities comprised in this investigation could be found four species of that
genus. Specimens from this research were determined as Sq. squalus and Sq. svallize. The
research was conducted on six rivers and lakes: Boljunšćica, Butoniga, Ljuta, Raša,
Trebišnjica and Visovac. Objectives of this research were to describe morphological
characteristics of species Sq. squalus and Sq. svalize from Adriatic Sea basin of Croatia and
Bosnia and Herzegovina, estabilish differences between same and different populations and
estimate if differences refer to presence of cryptic species. To establish variations
morphometric and meristic analysis were conducted. Morphometric characters were analysed
with various statistical methods and results of morphometric and meristic analysis were
compared with results from present investigations. Results of morphometric analysis has
shown either inter- and intrapopulation variability and the most interesting was groupation
between population of Sq. squalus from Boljunšćica and Sq. svallize from Ljuta. Meristic
analysis has also shown variability among and between populations. Results of morphometric
and meristic analysis show the possibility of geneticaly caused variability which indicate need
for future research. Finally, results of this investigation represent a significant contribution to
the knowledge of morphology of fishes of genus Squalius and will be useful for future
research.
