AB  - Variability and relationship between phenological traits and leaf, acorn, and
tree size morphometric traits were examined in early and late bud-flushing groups of the
pedunculate oak population in the vicinity of Sremska Mitrovica, Serbia. According to
the obtained three-year results, there were no significant differences in tree size and leaf
morphometric characteristics between the early and late group. The effect of trees within
phenological groups was statistically significant and considerable, especially in leaf blade
width (lbw) and leaf area (la). Acorn length (acl) and acorn index (acinx) were significantly
influenced by phenological group, achieving moderate contribution of phenological group
to the total variation. There was a clear effect of phenological group on variation of
examined phenological traits. The effect of year of monitoring on the same traits was
not significant, but there was a clear effect of interaction between phenological group
and year, especially in case of traits describing the period from bud swelling until the
emergence of wrinkled leaves (f12a), unfolded leaves (f12b), and fully developed leaves
(f12g) and their ratio with the period from 8 March until the emergence of wrinkled leaves:
f12b/f02a and f12g/f02a ratio. Earlier phenology in warmer years is clearer in the early
bud-flushing group than in the late one. Periods between different bud swelling and
f12a, f12b, and f12g phenological phases were significantly shorter in 2017 (with a warm
April) than in 2015 (with moderate temperatures in March and April) in the early group,
but significantly longer in the late group. Examined traits were classified in six groups
based on their factorial loadings with the first six principal components rotated by Varimax
method, revealing strict distinction between traits by their original nature. In that sense,
all examined groups of traits could be considered as informative in variability studies of
pedunculate oak. The tree size traits (tree height and diameter at breast height) formed
the separate, fifth group, suggesting no close relationship of these traits with any other
examined characteristic. Both cluster analysis and PCA suggest distinct classification by
trees’ phenology, but also considerable differences by the second principal component
which is closely related to leaf size characteristics. The research should be continued on
variability between populations and progenies, especially with respect to phenological and
acorn morphometric traits. Understanding the phenological variations between early and
late oaks could be essential for designing robust forest adaptation management strategies.

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  - Cilj ovog istraživanja je da se prikažu florističke i ekološke karakteristike acidofilne šume bukve sa mahovinama (Musco - Fagetum moesiacae B. Jov. 1976) na kiselom smeđem zemljištu, na području Jelove gore. U ovoj zajednici zabeleženo je 10 biljnih vrsta, od toga 8 vaskularnih biljaka i dve vrste mahovina (Polytrichum commune i Leucobryum glaucum), pa se može zaključiti da je zajednica floristički siromašna. Na osnovu florističkog sastava urađeni su spektri životnih oblika i ekološki spektri. Najveće učešće u zajednici imaju fanerofite. Rezultati istraživanja su pokazali da je ova šumska zajednica prema vlažnosti mezofilna, prema kiselosti acidofilno-neutrofilna, prema snabdevenosti zemljišta azotom mezotrofna, prema svetlosti sciofilno-polusciofilna, a prema toploti mezotermna.
AB  - The aim of this research to show floristic and ecological characteristics of acidophilus beach forest with mosses (Musco - Fagetum moesiacae B. Jov. 1976) in the area of Jelova gora. The studied type of soil in this forest community was dystric cambisol, which finds on sericite schist. Only ten plant species was recorded in this plant community (eight vascular plants and two species of mosses - Polytrichum commune and Leucobryum glaucum), so we can conclude that this plant community is very floristic poor. On bases floristic structure, spectrum of life forms and ekological spectrum are done. The phanerophytes have the highest share in community. The results of the study showed that investigated forest community was mesophilic, acidophilic to neutrofilic, mesotrophic, sciophilic to sub-sciophilic and mesothermophilic.
