    <ns1:description language="sr">Vrsta B. balcanicus je zvanično opisana 2002. godine. Naseljava potoke i
gornje tokove reka, koji su često pod antropogenim uticajem, pre svega u smislu stvaranja barijera. Barijere mogu da budu preduslov fragmentacije staništa koja utiče na ključne aspekte ekosistema, poput hidrološke povezanosti, što je od
presudnog značaja za ribe i druge vodene organizme.
Istraživanjem je obuhvaćeno devet populacija vrste B. balcanicus iz pet
reka koje pripadaju slivu Velike Morave. Rezultati analize strukture populacija
ukazuju na određeni stepen razlika između istraživanih lokaliteta. Genetičkom
karakterizacijom, na osnovu analize sekvenci COI gena mtDNK, potvrđeno je da
populacije obuhvaćene istraživanjem pripadaju vrsti B. balcanicus i konstatovan
je samo jedan haplotip - Ex65F1. Analizom geometrijske morfometrije potvrđeno je
postojanje polnog dimorfizma u veličini i obliku, kao i morfološka
varijabilnost između populacija uzrokovana fragmentacijom staništa. Najniže
vrednosti pokretljivosti spermatozoida konstatovane su u fragmentisanim
staništima, i u populaciji iz Petrovačke reke, koja je delimično zagađena. U ovoj
doktorskoj disertaciji predstavljen je prvi uspešan protokol za krioprezervaciju
spermatozoida potočne mrene. Primenom modifikovanog ESHIPPO-ILSFP-RP
modela procenjen je umereni rizik od nestajanja za populacije iz Grošničke reke,
na lokalitetima iznad i ispod akumulacije, kao i za Petrovačku reku.
Na osnovu izloženih rezultata može se zaključiti da je fragmentacija
staništa uticala na populacije potočne mrene u pogledu strukture populacija,
morfologije i reproduktivnog statusa, koji je predstavljen pokretljivošću
spermatozoida.

    <ns1:description language="en">The species B. balcanicus was officially described in 2002. This species inhabits
streams and the upper reaches of rivers, which are often altered by anthropogenic activity,
primarily by creating barriers. Barriers are a prerequisite for habitat fragmentation that
affects key aspects of ecosystems, such as hydrological connectivity, which is crucial for
fish and other aquatic organisms.
The research included nine populations of B. balcanicus from five rivers belonging
to the Velika Morava drainage. The population structure analysis indicated a certain
degree of difference between the investigated localities. Based on the mtDNA COI gene
sequences, genetic characterization confirmed that the populations included in this study
belong to the species B. balcanicus, with one haplotype detected - Ex65F1. Results of
geometric morphometry confirmed the existence of dimorphism in size and shape, and
morphological variability between populations, caused by habitat fragmentation. The
lowest sperm motility values were detected in fragmented habitats and in population from
the Petrovačka River, which is partially polluted. Within this doctoral dissertation, the first
successful protocol for cryopreservation of the Danube barbel sperm was presented.
Through the modified ESHIPPO-ILSFP-RP model was estimated a moderate risk of
extinction for the populations from the Grošnička River, in the localities above and below
the reservoir, as well as for the Petrovačka River population.
Based on the presented results, it can be concluded that habitat fragmentation
affected the Danube barbel populations in terms of population structure, morphology, and reproductive status, which is represented by sperm motility.
