Abstract
Opravili smo dendrokronološke raziskave hrasta (Quercus sp.) z Rožnika v Ljubljani. S pomočjo programa TSAP-Win smo sestavili lokalno kronologijo širin branik, za katero smo uporabili vzorce 20 hrastov. Vzorci so bili odvzeti iz dreves padlih po obsežnem žledolomu v letu 2014. Sestavili smo lokalno kronologijo dolgo 184 let, ki zajema branike nastale od leta 1830 do leta 2013. Kronologijo smo primerjali s hrastovimi kronologijami z različnih rastišč po Sloveniji, Avstriji, Madžarski, Hrvaški ter Srbiji. Raziskava telekonekcije je pokazala, da se kronologija z Rožnika statistično značilno (kazalnik TVBP>4) ujema z dvema hrastovima kronologijama iz Slovenije (Ljubljana z okolico pribl. 305 m n. m. in Novo mesto z okolico 188 m n.m., oddaljenost 61 km), ter dvema kronologijama iz Avstrije (Klagenfurt 462 m n.m., oddaljenost 65 km; Fechring 309 m n.m., oddaljenost 154 km). Kronologijo z Rožnika smo primerjali tudi z bukovimi (Fagus sylvatica L.) kronologijami iz različnih rastišč po Sloveniji. Raziskave heterokonekcije so pokazale, da se statistično značilno ujema s tremi kronologijami bukve iz različnih rastišč v Sloveniji (Mokronog 400 m n.m., oddaljenost 39 km; Mašun 1000 m n.m., oddaljenost 36 km; Celje, okolica 300 m n.m., oddaljenost 60 km).

Title:Local tree-ring chronologies of oak from Central Slovenia : B. Sc. thesis
Abstract:
We conducted dendrochronological investigations of oak (Quercus sp.) from the hill Rožnik in Ljubljana, central Slovenia. Using the TSAP-Win we performed measurements and constructed a local chronology, based on samples taken from 20 fallen oak trees. The samples (discs) were collected from fallen trees after a disastrous ice storm in 2014. The chronology is 184 years long and extends from 1830 to 2013. The chronology was compared with other oak chronologies from different sites in Slovenia, Austria, Hungary, Croatia and Serbia. Teleconnection survey showed that the chronology of Rožnik statistically agrees (TVBP>4) with two oak chronologies of Slovenia (the ones from Ljubljana 305 m a.s.l., and Novo mesto 188 a.s.l., distance 61 km), and two chronologies from Austria (Klagenfurt 462 m a.s.l., distance 65 km, and Fechring 309 m a.s.l., distance 154 km). The chronology of Rožnik was also compared with beech (Fagus sylvatica L.) chronologies from different sites in Slovenia. The heteroconnection research has shown that it statistically agrees (TVBP>4) with three chronologies of beech from different localities in Slovenia (Mokronog. 400 m a.s.l., distance 39 km; Mašun 1000 m a.s.l., distance 36 km; Celje 300 m a.s.l., distance 60 km).
