dc.description.abstractTokom tri vegetacione sezone mereni su fiziološki parametri: fotosinteza, transpiracija,  efikasnost iskorištavanja  vode (WUE), kao i parametri bioprodukcije na odabranim šumskim populacijama bukve  (Fagus sylvatica  L.), smrče (Picea abies (L.) Kartsen) i jele (Abies alba Mill.), čija su staništa na različitim nadmorskim visinama sa različitom  dostupnošću vode u zemljištu. Određivana je i zavisnost između položaja šumske zajednice na padini planine (nadmorska visina i nagib) i fotosinteze, odnosno bioprodukcije biljaka. Cilj istraživanja je bio da se precizno definiše mogući dalji trend geografskog pomeranja staništa odabranih biljnih vrsta koji je u korelaciji sa morfo-fiziološkim  adaptivnim odgovorom biljaka na promenu ekoloških uslova životne sredine.  Fotosintetička aktivnost tokom vegetacione sezone bila je stabilna ili se povećavala pri optimalnoj vlažnosti zemljišta. Na lokalitetima Tara i Kopaonik količina atmosferskih padavina nije igrala određujuću ulogu u dinamici fotosintetičke asimilacije CO2. Vlažnost zemljišta je na ovim lokalitetima bila visoka i stabilna zbog dreniranja vode sa  okolnih brda. Registrovane razlike u dinamici fotosinteze između ispitivanih vrsta povezane su sa različitim životnim ciklusom listopadnih i četinarskih vrsta i sa različitim fiziološkim adaptacionim strategijama na promene faktora spoljašnje sredine. Na dinamiku fotosintetičke asimilacije CO2 signifikantno utiče prosečna temperatura vazduha pre i tokom merenja, prosečna osmonedeljna količina padavina pre merenja, količina padavina na dan merenja, kao i momentalna vlažnost zemljišta (MVZ). Rezultati istraživanja ukazuju da će dejstvo klimatskih promena biti više izraženo na šumskim populacijama koje se nalaze na  vršnim, grebenskim lokalitetima većih nadmorskih visina, ili na padinama planina. Sušni periodi tokom vegetacione sezone, značajan su faktor pomeranja šuma planinskih lokaliteta. Bukove šume su dobro adaptirane na sušu i dobro podnose temperaturni stres, međutim, dugi periodi sa oskudnim padavinama izazivaju smanjenje asimilacije CO2 što ograničava značaj šuma u ublažavanju klimatskih promena.sr
dc.description.abstractDuring three vegetation seasons,  physiological parameters, such as  photosynthesis,  transpiration, water use efficiency  (WUE), as well as the parameters of bioproduction of the  beech (Fagus  sylvatica  L.), spruce (Picea  abies  (L.) Kartsen) and  fir (Abies  alba Mill.)  forest populations  have  been investigated depending on different altitude  mountain.  The relationship between  the photosynthesis  (and bioproduction)  of plants  and the  slope of the mountain is  also specified  according to  ecological parameters (water  regime and temperature.  The aim of this research is to define physiological status of forest mountain ecosystems in relation to the ecological conditions and predict further trend of geographic shift of the habitats, which is in  correlation with the  plant morpho-physiological adaptation responses on environmental  changes.  Photosynthetic activity during vegetation season was stable or increased  in optimal level of soil moisture  conditions. On the localities of Tara and Kopaonik the quantity of atmospheric precipitation did not play a determining role in the dynamics of photosynthetic assimilation of CO2. On these localities soil moisture was high and stable as a result of water running off from surrounding mountains.  Detected differences in the dynamics of photosynthesis of the tested species are result of  various lifecycles of  deciduous and coniferous trees and various physiological adaptation strategies.  The most influential effects on the dynamics of the photosynthesis of the  beech,  spruce and fir plants during the vegetation season were the following abiotic factors: average air temperature before measuring, temperature on the day of measuring,  eight-week amount of average precipitation before measuring, amount of precipitation  on the day of measuring  and  soil humidity. The analysis of the physiological parameters of the beech populations of various mountain  altitudes show that even if beech is sensitive to draught it has the physiological potential to keep its vitality by efficient managing water.  Effect of climatic changes will be more expressed in forests that can be found on high  altitude mountain reefs and peaks.  Beech forests tolerate temperature  and drought  stress, but long periods of  poor  precipitation  cause the decrease of CO2 assimilation which consequently decreases their importance in the global reduction of atmospheric CO2, i.e. limits their role in the  moderation  of climate change.en
