AB  - The pubescent oak (Quercus pubescens Willd.) leaves were analysed by the means of morphometric methods in the Outstanding Natural Landscape "Kosmaj" in Serbia. The main goals were to determine the level of intraspecific variability of pubescent oak leaves and to link it to local habitat conditions. Morphological analysis of size and shape (MASS) and landmark analyses were used for the investigation of the leaves, and observed differences were correlated to habitat conditions (altitude, slope, aspect) obtained by the digital terrain model. This study showed a clear pattern of intraspecific variability of leaf size and shape at a small spatial scale, and the presence of fluctuating asymmetry, length, and lobation differences as a response to local habitat conditions. The findings suggest that morphological variability can represent a useful tool for detecting changes in the environment, especially in areas where the pubescent oak is considered endangered.

AB  - Quercus petraea (Matt.) Liebl., Q. pubescens Willd., and Q. frainetto Ten. grow naturally in sympatry in the Landscape of Outstanding Features "Kosmaj" (Mt. Kosmaj) in Serbia, in the Western Balkans. The levels of genetic diversity and genetic structure in populations of these species (160 trees in total) was assessed by means of 14 nuclear microsatellites. The number of alleles detected in overall sample was 314, with the locus QrZAG90 being the most informative one in all three species (31, 35 and 36 alleles in Q. frainetto, Q. pubescens and Q. petraea, respectively). The levels of genetic diversity of all three species were relatively high (HE = 0.824, 0.834, and 0.794 in Q. petraea, Q. pubescens and Q. frainetto, respectively). Low but statistically significant inbreeding was detected in all three species (F = 0.100, 0.131 and 0.065 in Q. petraea, Q. pubescens and Q. frainetto, respectively), which, however, most likely reflects population substructure, which was observed in the STRUCTURE analysis. The optimal number of genetic groups revealed by Bayesian clustering analysis did not coincide with the number of analyzed species as it amounted to four (one gene pool was observed in each of the two species, Q. petraea and Q. pubescens, while two gene pools were observed in Q. pubescens). Furthermore, a higher level of hierarchical genetic structure, with six gene pools was found, with Q. frainetto being the only oak species in which population substructure was not observed. Genetic differentiation of three sympatric oak species was relatively low but statistically significant, with the highest FST value found among Q. petraea and Q. frainetto (FST = 0.047, P = 0.001), and the lowest between Q. petraea and Q. pubescens (FST = 0.032, P = 0.001). Our results reveal rather high levels of genetic diversity in all three studied oak species, which retained their genetic integrity despite sympatric distribution, indicating low levels of interspecific hybridization, and pronounced genetic structure of Q. pubescens and Q. petraea.

AB  - The sessile oak (Quercus petraea (Matt.) Liebl.) leaves were analysed using morphometric methods (landmarks, morphological analysis of size and shape) in the Region of outstanding features "Kosmaj" in Serbia. The main goals were to determine the level of intraspecific variability of the sessile oak leaves and to link it to local habitat conditions. The observed differences were correlated to altitude, slope and aspect, obtained by the digital terrain model. This study showed a specific pattern of intraspecific variability of leaf size and shape at a small spatial scale, and the presence of fluctuating asymmetry, length, roundness and lobation differences as a response to local habitat conditions. Additionally, specific allometric patterns were observed. Despite a relatively small sample size compared to the area of occurrence of the sessile oak, this study provided evidence that the variability of the size and shape of this species' leaves is, at least in part, related to environmental factors.
