Description (srp)

U ovoj disertaciji, urađena je do sada najobimnija genetička i ekološka analizapopulacija potočne pastrmke sa teritorije Srbije. Rezultati disertacije pružili su novi uvid ufilogeniju i filogeografiju kompleksa potočne pastrmke sa znatno šireg areala taksona. Zateritoriju Srbije, detektovano je gotovo dvostruko više haplotipova u odnosu na prethodnestudije. Haplotipska raznovrsnost dunavske filogenetske linije u Srbiji je veoma visoka upoređenju sa drugim regionima u slivu Dunava, što se ogleda kroz prisustvo haplotipova izDA-ES i DA-BS haplogrupa, kao i iz novopisane DA-INT haplogrupe. Suprotno uobičajenomuverenju, rezultati ove disertacije jasno pokazuju da se diverzifikacija unutar kompleksapotočne pastrmke odigrala u kasnom pliocenu, a ne u pleistocenu. Primenom mikrosatelitskihmarkera detektovana je složena populaciona struktura potočne pastrmke u Srbiji. Međutim, uodnosu na prethodne studije, zabeležen je viši nivo introgresije i introgresivne hibridizacijeizmeđu autohtone dunavske linije potočne pastrmke i alohtonih filogenetskih linija.Razvijanjem modela ESHIPPOsalmo utvrđen je umeren stepen održivosti za gotovo polovinuanaliziranih populacija, dok je za šest populacija utvrđen nizak stepen održivosti. U ciljukonzervacije populacija potočne pastrmke, za teritoriju Srbije, može se predložiti petevoluciono značajnih jedinica i 19 upravljačkih jedinica. Na primeru genotipizacije matičnogjata potočne pastrmke, ribnjaka „Panjica“, planiranog za poribljavanje ribolovnih voda Srbije,ukazano je na značaj monitoringa i upotrebe genetičkih markera u cilju uspostavljanja mera zaumanjenje štetnih efekata poribljavanja. Za očuvanje populacija potočne pastrmke sa teritorijeSrbije, neophodno je unaprediti i pravilno sprovoditi upravljanje populacijama.

Description (eng)

In this dissertation, the most extensive genetic and ecological analysis of brown troutpopulations from Serbia to date has been conducted. The obtained results also provide newinsight into the phylogeny and phylogeography of the brown trout species complex from amuch wider taxon area. For Serbia, almost twice as many haplotypes were detected comparedto previous studies. The haplotype diversity of the Danubian lineage in Serbia is highercompared to other regions in the Danube basin, which is reflected in the presence ofhaplotypes from the DA-ES and DA-BS, as well as the newly described DA-INT haplogroup.Contrary to common belief, the results of this dissertation clearly show that diversificationwithin the brown trout complex took place in the late Pliocene, not the Pleistocene. Acomplex population structure of brown trout in Serbia was detected by applying microsatellitemarkers. However, compared to previous studies, a higher level of introgression andintrogressive hybridization was recorded between the autochthonous Danubian andallochthonous lineages. Development of the ESHIPPOsalmo model determined a moderatelevel of sustainability for almost half of the analyzed populations, while a low sustainabilitylevel was determined for six populations. Five Evolutionarily significant units and 19Management units can be proposed to conserve brown trout populations in Serbia. Bygenotyping the "Panjica" hatchery brown trout broodstock planned for stocking the fishingwaters of Serbia, the importance of monitoring and usage of genetic markers was indicated toestablish measures for reducing the adverse effects of stocking. In order to preserve thepopulation of brown trout from Serbia, it is necessary to improve and adequately implementpopulation management.
