Abstract

Ovim istraživanjem obuhvaćene su populacije drlje (Scardinius dergle) i peškelja
(Scardinius plotizza) iz cijelog područja njihove rasprostranjenosti u Hrvatskoj i Bosni i
Hercegovini, kao i dostupni podatci iz banke gena za ostale vrste unutar ovog roda na
području jadranskog slijeva. Na svim istraživanim jedinkama analizirano je 25
morfometrijskih značajki, provedene su morfometrijske, merističke i fenološke analize
te su dobiveni podatci opisani deskriptivnom statistikom i inferencijalnim statističkim
metodama. Provedene su i filogenetičke analize istraživanih populacija temeljem
genskih biljega za citokrom b, beta aktin i BMP te je utvrđena genska raznolikost, kao i
molekularna dijagnostika populacija. Posebno je dan osvrt na taksonomski problem
populacije iz Vranskog jezera na otoku Cresu. Dobiveni rezultati pokazuju jasno
odvajanje pojedinih istraživanih populacija temeljem provedenih morfoloških analiza
što je provjereno i filogenetičkim analizama te su doneseni zaključci o međusobnim
odnosima i raznolikosti istraživanih populacija.

Abstract (english)

This research included populations of Scardinius dergle and Scardinius plotizza from
their entire distribution area in Croatia and Bosnia and Herzegovina, as well as available
data from the gene bank for other species within this genus in the Adriatic basin. In total
25 morphometric characteristics were analysed. Morphometric, meristic and
phenological features were explored, and analysed by descriptive statistics and
inferential statistical methods. Phylogenetic analyses of the studied populations based
on genetic markers for cytochrome b, beta actin and BMP were conducted, and genetic
diversity was determined, as well as molecular diagnostics for populations. The
taxonomic problem related to the population from the Lake Vrana on the Cres Island is
also addressed. The obtained results show a distinct separation of some populations
based on morphological analyzes, which were verified with phylogenetic analyzes, and
final conclusions were made regarding relationships and diversity of the studied
populations.
