Title: Stable carbon isotopes in Norwey spruce (Picea abies (L.) Karst.) tree rings at two sites in Slovenia Authors: ID Hafner, Polona (Author) ID Levanič, Tom (Author) Files: PDF - Presentation file, download (1,07 MB) MD5: 47D0485CF6F8E91C16E5D9D667A1F057 PID: 20.500.12556/dirros/d49c022b-e114-40b6-a4f3-e9d7379953b6   Language: English Typology: 1.01 - Original Scientific Article Organization: SciVie - Slovenian Forestry Institute Abstract: Stable isotopes in tree rings are an important tool in climate reconstruction and in studies of tree response on environmental factors in the past, similar like maximum latewood density, tree ring width and other tree ring parameters.In this article we present stable carbon isotopes physiology and the first two Slovenian d13C chronologies for Norway spruce (Picea abies (L.) Karst.) growing at two sites with different ecological conditions. Five trees were sampled at Pokljuka alpine site and three at Sorško polje lowland plantation. d13C values were compared with CRU TS 1.2 meteorological data-set,which provides information on climate in Europe for the 1901-2000 period at a 10ć spatial resolution. Results of correlation analysis for both sites revealed similar average d13C values, which are in strong negative correlation with amount of precipitation and positive correlation with temperatures in the growing period. Temporal stability of the correlation between precipitation and d13C values in July is significant for both sites, where as the stability of d13C - temperature relationship is significant only for the Sorško polje site.

Title:	Stabilna ogljikova izotopa v branikah smreke (Picea abies (L.) Karst.) na dveh rastiščih v Sloveniji
Abstract:	Stabilni izotopi v branikah dreves so, tako kot širine branik, maksimalna gostota kasnega lesa in drugi parametri branike, pomembno orodje pri rekonstrukciji klime v preteklosti in preučevanju odziva dreves na okoljske dejavnike. V prispevku predstavljamo fiziologijo stabilnih ogljikovih izotopovin prve slovenske d13C-kronologije smreke (Picea abies (L.) Karst.) nadveh lokacijah z različnimi ekološkimi razmerami. Na visokogorskem rastišču Pokljuka smo odvzeli vzorce petih, v nižinskem nasadu na Sorškem polju pa trehdreves. Vrednosti d13C smo primerjali s podatki CRU TS 1.2 meteorološke baze, ki vsebuje podatke o klimi za obdobje 1901-2000 v Evropi, s prostorsko ločljivostjo10ć. Rezultati korelacijske analize so pokazali, da je na obeh rastiščih povprečna d13C-vrednost podobna in v močni negativni korelaciji s količino padavin ter v pozitivni korelaciji z visokimi temperaturami v vegetacijski sezoni. Stabilnost korelacijske povezanosti med padavinami v juliju in d13C je značilna za obe lokaciji, medtem ko se stabilnost odnosa d13C- temperature kaže le na Sorškem polju.
