AB  - The future performance of the widely abundant European beech ( Fagus sylvatica L.) across its ecological amplitude is uncertain. Although beech is considered drought -sensitive and thus negatively affected by drought events, scientific evidence indicating increasing drought vulnerability under climate change on a cross -regional scale remains elusive. While evaluating changes in climate sensitivity of secondary growth offers a promising avenue, studies from productive, closed -canopy forests suffer from knowledge gaps, especially regarding the natural variability of climate sensitivity and how it relates to radial growth as an indicator of tree vitality. Since beech is sensitive to drought, we in this study use a drought index as a climate variable to account for the combined effects of temperature and water availability and explore how the drought sensitivity of secondary growth varies temporally in dependence on growth variability, growth trends, and climatic water availability across the species ' ecological amplitude. Our results show that drought sensitivity is highly variable and non -stationary, though consistently higher at dry sites compared to moist sites. Increasing drought sensitivity can largely be explained by increasing climatic aridity, especially as it is exacerbated by climate change and trees ' rank progression within forest communities, as (co -)dominant trees are more sensitive to extra -canopy climatic conditions than trees embedded in understories. However, during the driest periods of the 20th century, growth showed clear signs of being decoupled from climate. This may indicate fundamental changes in system behavior and be early -warning signals of decreasing drought tolerance. The multiple significant interaction terms in our model elucidate the complexity of European beech 's drought sensitivity, which needs to be taken into consideration when assessing this species ' response to climate change.

AB  - With ongoing global warming, increasing water deficits promote physiological stress on forest ecosystems with negative impacts on tree growth, vitality, and survival. How individual tree species will react to increased drought stress is therefore a key research question to address for carbon accounting and the development of climate change mitigation strategies. Recent tree-ring studies have shown that trees at higher latitudes will benefit from warmer temperatures, yet this is likely highly species-dependent and less well-known for more temperate tree species. Using a unique pan-European tree-ring network of 26,430 European beech (Fagus sylvatica L.) trees from 2118 sites, we applied a linear mixed-effects modeling framework to (i) explain variation in climate-dependent growth and (ii) project growth for the near future (2021–2050) across the entire distribution of beech. We modeled the spatial pattern of radial growth responses to annually varying climate as a function of mean climate conditions (mean annual temperature, mean annual climatic water balance, and continentality). Over the calibration period (1952–2011), the model yielded high regional explanatory power (R2 = 0.38–0.72). Considering a moderate climate change scenario (CMIP6 SSP2-4.5), beech growth is projected to decrease in the future across most of its distribution range. In particular, projected growth decreases by 12%–18% (interquartile range) in northwestern Central Europe and by 11%–21% in the Mediterranean region. In contrast, climate-driven growth increases are limited to around 13% of the current occurrence, where the historical mean annual temperature was below ~6°C. More specifically, the model predicts a 3%–24% growth increase in the high-elevation clusters of the Alps and Carpathian Arc. Notably, we find little potential for future growth increases (−10 to +2%) at the poleward leading edge in southern Scandinavia. Because in this region beech growth is found to be primarily water-limited, a northward shift in its distributional range will be constrained by water availability.

AB  - Key message We applied the generalized algebraic difference approach (GADA) to develop dynamic models of height growth for pedunculate oak (Quercus robur L.) in Serbia. According to the dominant heights, the studied region comprises some of Europe's most productive sites for pedunculate oak. Therein, we have generated a map showing the current site index class of stands. Such a map could be used to enhance forest management and evaluate climate change impacts. Context Although sustainable forest management requires reliable prediction of forest site productivity, such indicators are currently unavailable for pedunculate oak sites in Serbia. The site index (SI) curves represent the most commonly used indirect scale for site productivity classification. The dynamic equations derived by the Generalized Algebraic Difference Approach (GADA) are the state-of-the-art approach in growth modeling, but they have not been widely applied for studying the height dynamics of pedunculate oak. Aims The main objectives of this study were to develop the first dynamic site index curves for pedunculate oak in Serbia and subsequently to provide stand-level maps with predicted site indices. Methods We have tested five flexible polymorphic equations with variable asymptotes derived by the GADA approach. Models were calibrated using artificially established growth trajectories obtained from 3636 detailed temporary sample plots. The selection of the most suitable model was accomplished according to (1) quantitative measures of goodness of fit, (2) the analysis of residual scattering, and (3) the biological plausibility of obtained height growth curves. Results After correcting the error terms with a continuous first-order autoregressive structure and conducting a three-stage performance analysis, the GADA dynamic site index model derived from the Hossfeld base equation shows the best overall properties. Insight into the oscillations of relative error suggested that 100 years is the most suitable age for site index referencing. Comparison with existing height growth models revealed greater flexibility and a considerably better representation of the height growth dynamic of pedunculate oak in the studied region. Additionally, we have produced a spatially explicit map showing the expected SI100 for 1907 stands with pedunculate oak within 22 management units. Conclusion Dynamic SI-curves based on GADA will serve forest practitioners to update management plans and serve as a reference point for benchmarking the impact of climate change and for developing adaptation strategies. The utilized approach allowed unbiased estimation of SI100 across all age classes so that the results could be mapped at a broader scale. This study provides the second known application of the dynamic model for pedunculate oak in Europe but the first that includes some of the most productive sites in the species distribution range.

Additionally, we have produced a spatially explicit map showing the expected SI100 for 1907 stands with pedunculate oak within 22 management units. Conclusion Dynamic SI-curves based on GADA will serve forest practitioners to update management plans and serve as a reference point for benchmarking the impact of climate change and for developing adaptation strategies. The utilized approach allowed unbiased estimation of SI100 across all age classes so that the results could be mapped at a broader scale. This study provides the second known application of the dynamic model for pedunculate oak in Europe but the first that includes some of the most productive sites in the species distribution range.",

AB  - Process-based models and empirical modelling techniques are frequently used to (i) explore the sensitivity of tree growth to environmental variables, and (ii) predict the future growth of trees and forest stands under climate change scenarios. However, modelling approaches substantially influence predictions of the sensitivity of trees to environmen-tal factors. Here, we used tree-ring width (TRW) data from 1630 beech trees from a network of 70 plots established across European mountains to build empirical predictive growth models using various modelling approaches. In addi-tion, we used 3-PG and Biome-BGCMuSo process-based models to compare growth predictions with derived empirical models. Results revealed similar prediction errors (RMSE) across models ranging between 3.71 and 7.54 cm2 of basal area increment (BAI). The models explained most of the variability in BAI ranging from 54 % to 87 %. Selected explan-atory variables (despite being statistically highly significant) and the pattern of the growth sensitivity differed between models substantially. We identified only five factors with the same effect and the same sensitivity pattern in all empir-ical models: tree DBH, competition index, elevation, Gini index of DBH, and soil silt content. However, the sensitivity to most of the climate variables was low and inconsistent among the empirical models. Both empirical and process -based models suggest that beech in European mountains will, on average, likely experience better growth conditions under both 4.5 and 8.5 RCP scenarios. The process-based models indicated that beech may grow better across European mountains by 1.05 to 1.4 times in warmer conditions. The empirical models identified several drivers of tree growth that are not included in the current process-based models (e.g., different nutrients) but may have a sub-stantial effect on final results, particularly if they are limiting factors. Hence, future development of process-based models may build upon our findings to increase their ability to correctly capture ecosystem dynamics.

AB  - The growth of past, present, and future forests was, is and will be affected by climate variability. This multifaceted relationship has been assessed in several regional studies, but spatially resolved, large-scale analyses are largely missing so far. Here we estimate recent changes in growth of 5800 beech trees (Fagus sylvatica L.) from 324 sites, representing the full geographic and climatic range of species. Future growth trends were predicted considering state-of-the-art climate scenarios. The validated models indicate growth declines across large region of the distribution in recent decades, and project severe future growth declines ranging from -20% to more than -50% by 2090, depending on the region and climate change scenario (i.e. CMIP6 SSP1-2.6 and SSP5-8.5). Forecasted forest productivity losses are most striking towards the southern distribution limit of Fagus sylvatica, in regions where persisting atmospheric high-pressure systems are expected to increase drought severity. The projected 21(st) century growth changes across Europe indicate serious ecological and economic consequences that require immediate forest adaptation. Tree ring data from a network of beech tree stands across Europe show evidence for a recent growth decline from 1986-2016 and project up to 50% growth reductions in some areas of Europe with future climate change.

AB  - The mechanistic pathways connecting ocean-atmosphere variability and terrestrial productivity are well-established theoretically, but remain challenging to quantify empirically. Such quantification will greatly improve the assessment and prediction of changes in terrestrial carbon sequestration in response to dynamically induced climatic extremes. The jet stream latitude (JSL) over the North Atlantic-European domain provides a synthetic and robust physical framework that integrates climate variability not accounted for by atmospheric circulation patterns alone. Surface climate impacts of north-south summer JSL displacements are not uniform across Europe, but rather create a northwestern-southeastern dipole in forest productivity and radial-growth anomalies. Summer JSL variability over the eastern North Atlantic-European domain (5-40E) exerts the strongest impact on European beech, inducing anomalies of up to 30% in modelled gross primary productivity and 50% in radial tree growth. The net effects of JSL movements on terrestrial carbon fluxes depend on forest density, carbon stocks, and productivity imbalances across biogeographic regions. Here the authors show that extremes in the summer jet stream position over Europe create a beech forest productivity dipole between northwestern and southeastern Europe and can result in regional anomalies in forest carbon uptake and growth.

AB  - In central Bosnia and Herzegovina, in the Zavidovici-Teslic area, the study of the radial growth of Austrian and Scots pine (autochthonous pine species) trees was conducted using the dendrochronological method in order to identify the differences between the species in terms of the influence of climatic variables on the tree ring formation. Trees were sampled in five experimental areas or five sites. The first site had a Scots pine stand, while the second had an Austrian pine stand, and the other three sites had mixed stands of Scots and Austrian pine. Cross-dating was conducted using visual on-screen techniques of CDendro software and statistical methods using Cofecha software. The tree ring series were standardized using the Arstan program and cubic smoothing spline. It produced Scots pine regional chronology, 145 years long (1870-2014), and Austrian pine regional chronology, 180 years long (1835-2014). Correlation analysis of the relationship between the index of tree-ring width and precipitation and temperature in the characteristic periods of the year showed a negative effect of temperature (except in winter months) and a positive effect of precipitation on the tree ring formation. The statistically significant dependence of the tree-ring width index on the SPEI indices indicates a significant impact of moisture deficiency on the tree ring formation in the period from June to August (r = 0.33 in June, r = 0.45 in July and r = 0.47 in August) for Scots pine and in the period from June to September (r = 0.36 in June, r = 0.43 in July, r = 0.47 in August and r = 0.30 in September) for Austrian pine. The analysis of the relationship between climatic parameters and the chronologies of Scots and Austrian pine shows similar relationships between radial growth and climate but the influence of climate is somewhat more pronounced in Austrian pine. In the study area, the radial growth of both tree species is significantly determined by climate conditions. In other words, the chronology of these species has a good climatic signal, especially the drought signal in the summer months.

AB  - Recent studies show that several tree species are spreading to higher latitudes and elevations due to climate change. European beech, presently dominating from the colline to the subalpine vegetation belt, is already present in upper montane subalpine forests and has a high potential to further advance to higher elevations in European mountain forests, where the temperature is predicted to further increase in the near future. Although essential for adaptive silviculture, it remains unknown whether the upward shift of beech could be assisted when it is mixed with Norway spruce or silver fir compared with mono-specific stands, as the species interactions under such conditions are hardly known. In this study, we posed the general hypotheses that the growth depending on age of European beech in mountain forests was similar in mono-specific and mixed-species stands and remained stable over time and space in the last two centuries. The scrutiny of these hypotheses was based on increment coring of 1240 dominant beech trees in 45 plots in mono-specific stands of beech and in 46 mixed mountain forests. We found that (i) on average, mean tree diameter increased linearly with age. The age trend was linear in both forest types, but the slope of the age-growth relationship was higher in mono-specific than in mixed mountain forests. (ii) Beech growth in mono-specific stands was stronger reduced with increasing elevation than that in mixed-species stands. (iii) Beech growth in mono-specific stands was on average higher than beech growth in mixed stands. However, at elevations  gt  1200 m, growth of beech in mixed stands was higher than that in mono-specific stands. Differences in the growth patterns among elevation zones are less pronounced now than in the past, in both mono-specific and mixed stands. As the higher and longer persisting growth rates extend the flexibility of suitable ages or size for tree harvest and removal, the longer-lasting growth may be of special relevance for multi-aged silviculture concepts. On top of their function for structure and habitat improvement, the remaining old trees may grow more in mass and value than assumed so far.

AB  - This study was mainly aimed at constructing polymorphic site index curves for beech in the central (Rudnik mountain - RU, about 15,000 ha) and eastern (Zagubica - ZA, about 7,000 ha) part of its distribution in Serbia. To obtain suitable height-age data and evaluate the best-fit growth model we used 107 felled dominant beech trees. The Korf, Korsun and Chapman-Richards growth functions per site class were first parameterized and then mutually compared with respect to residual statistics and the significance of their parameters. They were additionally parameterized in line with empirical data on the value and age of the culmination of current annual height increment (CAI(h)). The obtained results indicated that the Chapman-Richards growth function showed the best results both by statistical (residuals standard error, significance of the parameters, distribution of residuals, and homosccdasticity) and by empirical criteria (the CAI(h) culmination time, the maximal values of the CAI(h), and the attained height of trees at a certain age) of the height-age beech modelling in the analyzed regions. The obtained polymorphic site index curves which classify sites with regard to their productivity can be very helpful in planning appropriate silvicultural treatments, and for decision-making in forest management planning, forest policy and ecology and, consequently, in the sustainable management of beech forests in Serbia and some neighbouring countries with a similar forestry sector development.

AB  - Spruce-fir-beech mixed forests cover a large area in European mountain regions, with high ecological and socioeconomic importance. As elevation-zone systems they are highly affected by climate change, which is modifying species growth patterns and productivity shifts among species. The extent to which associated tree species can access resources and grow asynchronously may affect their resistance and persistence under climate change. Intra-specific synchrony in annual tree growth is a good indicator of species specific dependence on environmental conditions variability. However, little attention has been paid to explore the role of the inter-specific growth asynchrony in the adaptation of mixed forests to climate change. Here we used a database of 1790 treering series collected from 28 experimental plots in spruce-fir-beech mixed forests across Europe to explore how spatio-temporal patterns of the intra- and inter-specific growth synchrony relate to climate variation during the past century. We further examined whether synchrony in growth response to inter-annual environmental fluctuations depended on site conditions. We found that the inter-specific growth synchrony was always lower than the intra-specific synchrony, for both high (inter-annual fluctuations) and low frequency (mid- to long-term) growth variation, suggesting between species niche complementarity at both temporal levels. Intra- and inter -specific synchronies in inter-annual growth fluctuations significantly changed along elevation, being greater at higher elevations. Moreover, the climate warming likely induced temporal changes in synchrony, but the effect varied along the elevation gradient. The synchrony strongly intensified at lower elevations likely due to climate warming and drying conditions. Our results suggest that intra- and inter-specific growth synchrony can be used as an indicator of temporal niche complementarity among species. We conclude that spruce-fir-beech mixtures should be preferred against mono-specific forests to buffer climate change impacts in mountain regions.

AB  - In order to assess the impact of climate variations on Austrian pine forest in the Belgrade area, the radial growth of artificially-established Austrian pine trees and its dependence on temperature and precipitation was studied using dendroclimatological methods. The site is classified as Quercetum-froinetto cerris Rudski. Standard and residual chronologies were established and several common statistics were calculated. A dendroclimatic study was carried out using the correlation and response function analysis. The Pearson correlation coefficients between the chronology indices and 13 seasonal (3-month period) precipitation and temperature data were calculated for the period from 1959 to 2014. The applied response function analysis included 24 precipitation and temperature variables from October of the prior year to September of the current year. The results of the correlation analysis pointed out that there was a strong tendency towards a positive response to the summer and late summer/early autumn precipitation and a weak significant negative response to the spring and summer temperatures. Climate-growth relationships were further first studied using the response functions for the significant seasons that were detected from the correlation analysis and then for individual months from previous October to current September. These results also highlighted the findings that higher precipitation in the current summer months has a beneficial effect on the tree-ring width. The conducted correlation between the residual chronology and the Standardised Precipitation Evapotranspiration Index indicated that a high summer value of this drought index had a positive impact on the pine growth and reinforced the previously detected relevance of September as an important month for the Austrian pine growth. These preliminary results point out that some additional climate-Austrian pine growth studies (application of various tree-ring features, growth data with a much longer time span, more sites/stands, etc.) should be performed to obtain new and valuable knowledge important for the sustainable management of Austrian pine forests.

AB  - In Europe, mixed mountain forests, primarily comprised of Norway spruce (Picea abies (L.) Karst.), silver fir (Abies alba Mill.), and European beech (Fagus sylvatica L.), cover about 10 x 106 ha at elevations between similar to 600 and 1600 m a.s.l. These forests provide invaluable ecosystem services. However, the growth of these forests and the competition among their main species are expected to be strongly affected by climate warming. In this study, we analyzed the growth development of spruce, fir, and beech in moist mixed mountain forests in Europe over the last 300 years. Based on tree-ring analyses on long-term observational plots, we found for all three species (i) a nondecelerating, linear diameter growth trend spanning more than 300 years; (ii) increased growth levels and trends, the latter being particularly pronounced for fir and beech; and (iii) an elevation-dependent change of fir and beech growth. Whereas in the past, the growth was highest at lower elevations, today's growth is superior at higher elevations. This spatiotemporal pattern indicates significant changes in the growth and interspecific competition at the expense of spruce in mixed mountain forests. We discuss possible causes, consequences, and silvicultural implications of these distinct growth changes in mixed mountain forests.

AB  - Mixed mountain forests of European beech (Fagus sylvatica L.), Norway spruce (Picea abies (L.) Karst), and silver fir (Abies alba Mill.) cover a total area of more than 10 million hectares in Europe. Due to altitudinal zoning, these forests are particularly vulnerable to climate change. However, as little is known about the long-term development of the productivity and the adaptation and mitigation potential of these forest systems in Europe, reliable information on productivity is required for sustainable forest management. Using generalized additive mixed models this study investigated 60 long-term experimental plots and provides information about the productivity of mixed mountain forests across a variety of European mountain areas in a standardized way for the first time. The average periodic annual volume increment (PAI) of these forests amounts to 9.3 m(3)ha(-1)y(-1). Despite a significant increase in annual mean temperature the PAI has not changed significantly over the last 30 years. However, at the species level, we found significant changes in the growth dynamics. While beech had a PAI of 8.2 m(3)ha(-1)y(-1) over the entire period (1980-2010), the PAI of spruce dropped significantly from 14.2 to 10.8 m(3)ha(-1)y(-1), and the PAI of fir rose significantly from 7.2 to 11.3 m(3)ha(-1)y(-1). Consequently, we observed stable stand volume increments in relation to climate change.

AB  - Ring-width series are important for diverse fields of research such as the study of past climate, forest ecology, forest genetics, and the determination of origin (dendro-provenancing) or dating of archaeological objects. Recent research suggests diverging climate-growth relationships in tree-rings due to the cardinal direction of extracting the tree cores (i.e. direction-specific effect). This presents an understudied source of bias that potentially affects many data sets in tree-ring research. In this study, we investigated possible direction-specific growth variability based on an international (10 countries), multi-species (8 species) tree-ring width network encompassing 22 sites. To estimate the effect of direction-specific growth variability on climate-growth relationships, we applied a combination of three methods: An analysis of signal strength differences, a Principal Component Gradient Analysis and a test on the direction-specific differences in correlations between indexed ring-widths series and climate variables. We found no evidence for systematic direction-specific effects on tree radial growth variability in high-pass filtered ring-width series. In addition, direction-specific growth showed only marginal effects on climate-growth correlations. These findings therefore indicate that there is no consistent bias caused by coring direction in data sets used for diverse dendrochronological applications on relatively mesic sites within forests in flat terrain, as were studied here. However, in extremely dry, warm or cold environments, or on steep slopes, and for different life-forms such as shrubs, further research is advisable.

AB  - The influence of temperature and precipitation on the growth of artificially estab-lished black pine trees in the area of Mountain Rudnik was studied in this paper. For that purpose, we bored 50 series of radial increment from 25 dominant trees. The aforementioned influence was analyzed by applying three procedures: a correlation between seasonal values of temperature and precipitation and RES chronologies of radial increment, a correlation between monthly temperature and precipitation data and RES chronologies, and response function anal-ysis. The results have shown that black pine was very sensitive towards the precipitation in summer months in the given conditions, in the way that higher amounts of summer precipita-tion resulted in significantly higher radial increment values. The variations of radial increment were less conditioned by temperature oscillations, whereby the week negative influence of July temperatures on the increment values was detected. It was concluded that the reaction of black pine in the investigated site in terms of increment and its dependence on climate was similar to the reaction of this species in Serbia and other neighbouring countries characterized by similar climate conditions.

AB  - U radu su prikazani rezultati dendroklimatološke analize rasta jele na po-dručju planine Borja, Bosna i Hercegovina. Potrebni podaci su uzeti na 2 lokaliteta, a uzorkom je obuhvaćeno ukupno 60 serija radijalnog prirasta (15 dominantnih stabala po lokalitetu sa po dva izvrtka). Provedena je standardna dendrohronološka obrada i analiza podataka primenom softvera Coffecha i Arstan.

Dobijeni rezultati korelacione analize između indeksa radijalnog prirasta de-finisane hronologije, sa jedne strane i padavina i temperature po mesecima, sa druge strane, pokazali su da veće količine padavina u leto izraženo povećavaju prirast jele, a da povećanje temperature u ovim mesecima ne izaziva značajnu redukciju prirasta. Rezultati primene FAI indeksa suše u navedene svrhe pokazali su da intenzivnije suše u letnjim mesecima mogu izazvati značajnu redukciju prirasta jele na datom području.
AB  - This paper presents the results of a dendroclimatological analysis of the growth of fir trees in the Borja mountain area, Bosnia and Herzegovina. The required data were taken in 2 sites, and the sample covered a total of 60 series of radial increment (15 dominant trees per site with two cores). Standard dendrochronological processing and data analyses using the Coffecha and Arstan software were performed. The preliminary 137-years long regional fir chronology for the Borja mountain area was obtained. The obtained results of the correlation analysis between the radial increment index of the defined chronology, on the one hand, and the monthly precipitation and temperature, on the other, showed that higher summer pre-cipitation significantly increased the increment of fir, and that the increase in temperature in these months did not not cause a significant increment reduction. However, the results of the FAI drought index application for the stated purposes have shown that more intense droughts in the summer months can cause a significant reduction in the increment of fir in a given area.

AB  - This paper reports on the size and completeness of tree crowns and their effectiveness for the production of wood volumes in the case of a pure 35-years European ash stand. Starting from the interaction between the elements of the crowns structure and elements of the tree and stand growth the economical use of growing space was perceived and the optimal stand state was also defined, what were the main objectives of this paper. The trees with slender crowns, despite their better ratio of the surface area/volume of the crown, produced lower wood volume (undeveloped crowns). On the other hand, when the produced stem volume was analyzed per unit growing space it was observed that the less space for tree growth the more effectively it was used for the production of wood volume. This indicated the existence of a certain optimum between the crowns and produced volume stands. The optimal stand state in terms of crown structure, the desired number of trees and stand volume was determined based on the relationship between the coefficient of the economy of growing space utilization and volume of trees and crown projection area.

AB  - Data on average age and height of dominant moesian beech trees from 109 temporary sample plots were used to establish anamorphic site index curves (SI) calculated from seven growth functions (Chapman-Richards, Korf, Korsun, Hosfeld IV, Todorovic, Schumacher and Prodan). The base age for calculation of SI was 100 (SI100)). The guide curve method was applied. For the evaluation of the models, statistical as well as visual examinations were considered. The results showed that all the applied models had a relatively high coefficient of determination (R-2) value, indicating that the models accounted for more than 65% of the variation in the dominant height, which can be considered as large effects. Korsun's function shows the best overall statistics, which makes this model the most suitable for the construction of anamorphic site index curves for the study area. The obtained results are of importance for effective decision making in forest management planning, forest policy, and ecology in Serbia. Namely, regarding the relatively large sample and well-distributed sample units per age and site classes as well as the source of data (temporary sample plots), the developed site index curves and the method of stratifying the sites according to their productivity were performed for the first time in Serbia. Future studies should be performed in order to expand the knowledge on the dominant beech height-age relationships in the studied region using another well-known procedure of site index construction - polymorphic site index curves and stem analysis data.

AB  - A dendroclimatological analysis of Sessile oak has been carried out for the first time in Serbia on the area of National park "Fruska gora" (the northern part of Serbia). Two versions of chronology (standard and residual) were first established according to conventional dendrochronological procedures. To eliminate the chance of biasing the chronology indices and to extract climatic signals, the most important well known techniques were applied. The resulted chronologies span a period of 92 years from 1919 to 2010 and, according to the values of obtained parameters (r(bar), EPS, SNR and PC1) for a common period (1938-2010), it was concluded that the established chronologies possess a satisfactory level of common signal, which represents the common variability present in all series of radial increment in a given site condition. To ascertain the relationships between oak radial increment and monthly and seasonal precipitation and temperature data (1) correlation functions, (2) response functions and (3) pointer year's analysis were applied. It was obvious that radial increment of oak for the studied site was influenced more by precipitation than temperature. The tendency towards positive response to previous year's precipitation (especially in the period September-October) and negative response to current summer temperature (particularly in August) were recorded. The largest number of identified positive pointer years corresponded to wet previous September and October precipitation. The results described here represented a preliminary stage of dendroclimatological study of sessile oak for this region and for this reason future studies should be undertaken in order to expand data base and knowledge of the climate influence on sessile oak growth in the studied region as well as in many other regions in Serbia.

The resulted chronologies span a period of 92 years from 1919 to 2010 and, according to the values of obtained parameters (r(bar), EPS, SNR and PC1) for a common period (1938-2010), it was concluded that the established chronologies possess a satisfactory level of common signal, which represents the common variability present in all series of radial increment in a given site condition. To ascertain the relationships between oak radial increment and monthly and seasonal precipitation and temperature data (1) correlation functions, (2) response functions and (3) pointer year's analysis were applied. It was obvious that radial increment of oak for the studied site was influenced more by precipitation than temperature. The tendency towards positive response to previous year's precipitation (especially in the period September-October) and negative response to current summer temperature (particularly in August) were recorded. The largest number of identified positive pointer years corresponded to wet previous September and October precipitation. The results described here represented a preliminary stage of dendroclimatological study of sessile oak for this region and for this reason future studies should be undertaken in order to expand data base and knowledge of the climate influence on sessile oak growth in the studied region as well as in many other regions in Serbia.",

AB  - This paper presents the first regional research of the chronologies of sessile oak trees and definition of the local (master) chronology of sessile oak in the area of Fruška Gora. In addition, the aim of this study is to determine the strength of the common signal in the growth of sessile oak and its dendroclimatological potentialunder the given conditions. The quality of the local series of radial increment (chronology) and the strength of the common and climatic signals were evaluated using the following parameters: average mean sensitivity, expressed population signal, signal-to-noise ratio and the variance explained by eigenvectors in the procedure of analysis of the principal components. The results have shown that the obtained master chronologies are of satisfactory quality and reliability, and that they contain a sufficient general common 'signal', which is a characteristic of all analyzed trees that can be processed in all dendroclimatological analyses. It was concluded that, under the investigated site conditions, sessile oak showed low to medium sensitivity of reaction to the modifications of environmental conditions in the past 90 years.

The pointer years were determined by the Schweingruber (1983) methodology. The years with distintive tree rings were defined as the years of beech growth with very pronounced distinctive growth rings (annual ring width at least ± 2 standard deviations higher or lower than the arithmetic mean) and pronounced typical growth rings (annual ring width at least ± 1.5 standard deviation higher or lower than the arithmetic mean). The common pointer years for the growth of beech in the site conditions of all three ecological units are 1977 and 1988 (negative pointer years). A particular pointer year is 1988, when in more than 90% of trees under the analyzed environmental conditions the marked reduction of tree rings width of the trees (EUB) or very pronounced reduction in the width of tree rings (EUA and ESV) were observed.

AB  - Dendrochronological investigations of Scots pine (Pinus sylvestris L) growing on Mannikjarve peatland in central Estonia showed that annual tree growth of peatland pines can be used as a proxy for past variations of water table levels. Reconstruction of past water table levels can help us to better understand the dynamics of various ecological processes in peatlands, e.g. the formation of vegetation patterns or carbon and nitrogen cycling. Mannikjarve bog has one of the longest water table records in the boreal zone, continuously monitored since 1956. Common uncertainties encountered while working with peatland trees (e.g. narrow, missing and wedging rings) were in our case exacerbated with difficulties related to the instability of the relationship between tree growth and peatland environment. We hypothesized that the instable relationship was mainly due to a significant change of the limiting factor, i.e. the rise of the water table level due to human activity. To test our hypothesis we had to use several novel methods of tree-ring chronology analysis as well as to test explicitly whether undetected missing rings biased our results. Since the hypothesis that the instable relationship between tree growth and environment was caused by a change in limiting factor could not be rejected, we proceeded to find possible significant changes of past water table levels using structural analysis of the tree-ring chronologies. Our main conclusions were that peatland pines can be proxies to water table levels and that there were several shifting periods of high and low water table levels in the past 200 years.

AB  - The problem of estimating biomass and carbon stock in beech high stands that have specific structural form and that used to be virgin forests at the beginning of the twentieth century was investigated. A set of five stands was selected. Their site class is II-IV and the altitude ranges from 450 to 1050 m. A systematic sample of circular sample plots of 500 m(2) in size was applied. A set of 111 established sample plots altogether was used for the measurements of diameters and heights of all living trees and dead (standing and fallen) wood. Regression equations for European beech (WUTZLER et al., 2008; JOOSTEN et al., 2004) were used for the purposes of calculating total biomass and tree carbon stock. Biomass of dead wood was calculated on the basis of wood volume and density (MUND, 2004). The estimated average above and belowground wood biomass (p = 0.95) of all stands is 310 +/- 19.31 t ha(-1), while the estimated average carbon stock amounts to 153 +/- 9.55 tC ha(-1). It can be concluded that the beech stands in Eastern Serbia have reduced biomass and carbon stock due to inadequate implementation of management systems.

AB  - U našoj šumarskoj nauci i operativi brojnost i raznovrsnost drvenastih vrsta u šumskim sastojinama ocenjivane su najčešće preko ukupnog broja vrsta drveća, što je metodološki delimično neadekvatan pristup. Stoga je u ovom radu kvantifikacija brojnosti i ocena raznovrsnosti drvenastih vrsta u mešovitim šumama bukve sa plemenitim lišćarima na području Nacionalnog parka 'Đerdap' analizirana pomoću pet različitih indeksa brojnosti vrsta: broja vrsta (S indeks), dva indeksa brojnosti vrsta (R1 i R2), očekivanog broja vrsta pri uzorku sa jednakim brojem stabala (E(S84)) i očekivanog broja pri uzorku jednake površine (E(S0,25ha)). Rezultati su pokazali da ocena nivoa raznovrsnosti drvenastih vrsta u šumskim sastojinama zavisi od primenjenog indeksa kojim se karakteriše brojnost vrsta drveća. Zaključeno je da su brojnost i raznovrsnost drvenastih vrsta najveće u sastojinama ekološke jedinice B (E(S84)=8,6 vrsta) i ekološke jedinice G (E(S0,25ha)=9,4 vrsta), a najmanje u sastojinama ekološke jedinice V (E(S84)=5,8 vrsta, E(S0,25ha)=5,5 vrsta).
AB  - In our forest science and forest operations, the tree species richness and diversity of woody species in forest stands are most often evaluated based on the total number of tree species, which is a methodologically partly inadequate approach. For this reason, the quantification and the evaluation of diversity of woody species in mixed forests of beech with valuable broadleaves in the area of the National Park 'Đerdap' were analyzed by five different indices of tree species richness: number of species (S index), two indices of the species richness (R1 and R2), expected number of species in the sample with equal numbers of trees (E(S84)), and expected number of species in the sample with equal areas (E(S0,25ha)). The results showed that the level of woody species diversity in forest stands depended on the applied index characterizing the tree species richness. It was concluded that the tree species richness and diversity were the highest in the stands of ecological unit B (E(S84)=8.6 species) and in the stands of ecological unit G (E(S0,25ha)=9.4 species), and they were the lowest in the stands of ecological unit V (E(S84)=5.8 species, E(S0,25ha)=5.5 species).

abstract = "U našoj šumarskoj nauci i operativi brojnost i raznovrsnost drvenastih vrsta u šumskim sastojinama ocenjivane su najčešće preko ukupnog broja vrsta drveća, što je metodološki delimično neadekvatan pristup. Stoga je u ovom radu kvantifikacija brojnosti i ocena raznovrsnosti drvenastih vrsta u mešovitim šumama bukve sa plemenitim lišćarima na području Nacionalnog parka 'Đerdap' analizirana pomoću pet različitih indeksa brojnosti vrsta: broja vrsta (S indeks), dva indeksa brojnosti vrsta (R1 i R2), očekivanog broja vrsta pri uzorku sa jednakim brojem stabala (E(S84)) i očekivanog broja pri uzorku jednake površine (E(S0,25ha)). Rezultati su pokazali da ocena nivoa raznovrsnosti drvenastih vrsta u šumskim sastojinama zavisi od primenjenog indeksa kojim se karakteriše brojnost vrsta drveća. Zaključeno je da su brojnost i raznovrsnost drvenastih vrsta najveće u sastojinama ekološke jedinice B (E(S84)=8,6 vrsta) i ekološke jedinice G (E(S0,25ha)=9,4 vrsta), a najmanje u sastojinama ekološke jedinice V (E(S84)=5,8 vrsta, E(S0,25ha)=5,5 vrsta)., In our forest science and forest operations, the tree species richness and diversity of woody species in forest stands are most often evaluated based on the total number of tree species, which is a methodologically partly inadequate approach. For this reason, the quantification and the evaluation of diversity of woody species in mixed forests of beech with valuable broadleaves in the area of the National Park 'Đerdap' were analyzed by five different indices of tree species richness: number of species (S index), two indices of the species richness (R1 and R2), expected number of species in the sample with equal numbers of trees (E(S84)), and expected number of species in the sample with equal areas (E(S0,25ha)). The results showed that the level of woody species diversity in forest stands depended on the applied index characterizing the tree species richness. It was concluded that the tree species richness and diversity were the highest in the stands of ecological unit B (E(S84)=8.6 species) and in the stands of ecological unit G (E(S0,25ha)=9.4 species), and they were the lowest in the stands of ecological unit V (E(S84)=5.8 species, E(S0,25ha)=5.5 species).",

AB  - Istraživanja su obavljena u dva zasada bele vrbe (Salix alba L.) u Donjem Sremu na zemljištu tipa humoglej (ritska crnica) koje pripada šumi poljskog jasena sa retkoklasim šašem (Carici remotae - Fraxinetum angustifoliae Jov. et Tom. 1979). Zasadi se nalaze u istoj depresiji, pri čemu je zasad OP-1 starosti 21 godinu sa razmakom sadnje 6×6 m, a zasad OP-2 starosti 27 godina sa razmakom sadnje 3×3 m. Elementi rasta stabala na OP- 1 su pokazali da bela vrba pri razmaku sadnje 6×6 m u planiranoj dužini proizvodnog ciklusa od 25 godina može da ostvari oko 250 m3·ha-1 drvne zapremine sa neto učešćem tehničkog drveta 80% i celuloznog drveta 20%. Zasad na OP-2 se nalazi u starosti koja je znatno iznad optimalne starosti sa aspekta racionalnog gazdovanja, a ukupna zapremina u 27 godina iznosi oko 300 m3·ha-1, sa neto učešćem tehničkog drveta od 53,7% i celuloznog drveta 46,3%.
AB  - The study was conducted in two plantations of white willow (Salix alba L.) in Donji Srem on the humogley soil type (hydromorphic black soil), which belongs to a narrow-leaved ash forest with remote sedge (Carici remotae - Fraxinetum angustifoliae Jov. et Tom., 1979). The plantations are located in the same depression. The SP (sample plot)-1 plantation is 21 years old with a 6×6 m planting spacing, and the SP-2 plantation is 27 years old with a 3×3m planting spacing. Elements of stem growth in the SP-1 plantation showed that with the white willow planting spacing of 6×6 m and a planned 25-year production cycle it is possible to obtain about 250 m3·ha-1 of timber volume, with an 80% net share of technical wood and a 20 % share of pulp wood. The plantation in SP-2 is at the age, which is well above the optimum age in terms of rational management, and the total volume at the age of 27 years is about 300 m3·ha-1, with a 53.7% net share of technical wood and a 46.3% share of pulpwood.
