Pregled odmiranja hrastov (Quercus spp.) v Evropi in pri nas [Elektronski vir] : magistrsko delo - 2. stopnja = Review of oak (Quercus spp.) decline in Europe and in Slovenia : M. Sc. Thesis - master study programmesPuhek, AljažNamen raziskave je bil s pregledom domače in tuje literature določiti najpomembnejše abiotske in biotske dejavnike odmiranja doba (Quercus robur), gradna (Q. petraea) in črnike (Q. ilex) v Evropi ter ... pri nas, in jim določiti nivo v Manionovi spirali propadanja. Pregledu literature je sledila še analiza podatkov Zavoda za gozdove Slovenije o poseku gradna in doba v obdobju 1995–2022 na območju Slovenije. Po pregledu literature smo zaključili, da na odmiranje gradna, doba in črnike vpliva kompleks abiotskih in biotskih škodljivih dejavnikov. Pri dobu in gradnu se kot poglaviten dejavnik predispozicije in hkrati tudi sprožilni dejavnik najpogosteje omenja sušni stres, katerega vpliv postaja s spreminjanjem podnebja vedno večji, od biotskih dejavnikov pa predvsem različne vrste gliv in fitoftor ter vnos najrazličnejših tujerodnih vrst (npr. podlubnikov). Varstveno-sanacijski posek in posek oslabelega drevja je v proučevanem obdobju pri dobu znašal kar približno 35 % skupne količine poseka oz. približno 204.000 m3, pri gradnu pa približno 27 % oz. približno 1.109.000 m3. Pri črniki se za razliko od gradna in doba glede ogroženosti bolj kot pomen abiotskih poudarja pomen biotskih dejavnikov, in sicer nekaterih vrst fitoftor in gliv. Abiotski dejavniki (predvsem suša) sicer v kombinaciji z biotskimi dejavniki prav tako predstavljajo pomemben vzrok za odmiranje črnike, vendar so v tem primeru bolj v vlogi dejavnikov predispozicije kot sprožilnih dejavnikov. Stanje črnike v Sloveniji trenutno bolj kot vse našteto v bistvu ogroža njena redkost.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
