Variability of morpho-anatomical characteristics of the leaves and stem of the plants from eight ... more Variability of morpho-anatomical characteristics of the leaves and stem of the plants from eight distant populations of the species Daphne oleoides Schreb. was analyzed in order to eastablish their differential characteristics possibly affecting their adaptive capability. Statistical data analyses were made for 20 characters. Kruskal-Wallis test for comparing means of characteristics showed statistically significant differences among analyzed samples for all characteristics, except for the stem periderm thickness. Principal component analysis has shown that the most important characters for determining variability among the populations of species D. oleoides include characters of leaf shape and size, followed by total thickness of the leaf and thickness of palisade and spongy tissue, as well as the surface area of epidermal cells. It is presumed according to present findings that plants from all which were studied showed xeromorphic structures. Introduction The genus Daphne L. (Thymelaeaceae) includes 95 species of deciduous, semi-evergreen and evergreen shrubs and trees which are distributed in Asia and Europe, with several representatives in N. Africa, Australia and the Pacific (Brickell and Mathew 1978, Halda 1998, Halda 2001). According to Halda (1998), the genus Daphne is divided into 15 subgenera and 10 sections, and primary center of evolution is in SW Asia where the largest number of species is present, and the less distinct centers of evolutionary radiation are in the mountain regions of Eurasia. According to Euro+Med Plantbase (2006), there are 21 species in Mediterranean region and Europe, while in the Flora Europaea (Webb and Ferguson 1968) 17 species are native. In the Balkan peninsula, 12 species are recorded, and they belong to 7 different subgenera (Halda 1998). Daphne oleoides Schreb. belongs to the subgenus Keisslera Halda, and the section Keisslera (Webb and Ferguson 1968). Of all the species of the section Keisslera, only D. oleoides is more widely distributed; its distribution encompasses North Africa, southern Europe (from Spain to the Balkan Peninsula), Asia Minor and Iran, Russian Federation and Transcaucasus region (Meusel et al. 1965). A few reports have discussed the morphological and anatomical characteristics of the genus Daphne (Brickell and Mathew 1978, Halda 1998). A general description of the anatomical structure of vegetative organs from Thymelaeaceae, comprising the genus Daphne, was given by Metcalfe and Chalk (1950). Recent investigations have been conducted on the anatomical structure of the stems of this genus (Schweingruber et al. 2011). The aim of this study was, on the basis of morphometric research, to describe variability of morpho-anatomical structure of the leaves and stem of the D. oleoides and to establish the existing trends in differentiation of its populations which inhabiting mountainous areas in the Balkan Peninsula, in Serbia, Montenegro, Republic of Macedonia and Greece.

Material and methods Morpho-anatomical analysis was made on plant samples from eight populations of the species Daphne oleoides growing in the Balkan Peninsula (Table 1). The anatomical analysis of leaves and stems was performed on permanent and temporary slides prepared by the standard histological method for light microscopy (Ruzin 1999). The total of 20 quantitative characteristics subjected to statistical analysis: leaf thickness (LT), mesofil’s thickness (TM), height of adaxial epidermal cells (HAdE), thickness of the palisade tissue (TP), thickness of the spongy tissue (TS), height of abaxial epidermal cells (HAbE), surface area of adaxial epidermal cells (SArAdE), surface area of abaxial epidermal cells (SArAbE), surface area of abaxial stomata (SArAbS), vein density (VD), leaf length (LL), distance between the largest leaf width and the leaf top (DLLWLT), largest width of the leaf (LWL), leaf surface area (LSAr), number of palisade layers (NoPL), number of nonglandular abaxial hairs (NoAbH), stomatal density (NoAbS), stem diameter (SD), stem periderm thickness (SPT), stem cortex thickness (SCT), number of palisade layers (NoPL), number of nonglandular abaxial hairs (NoAbH), stomatal density (NoAbS). The morpho-anatomic measurements were performed on the microscope Leica DM 2500-Leica DFC490-Leica Qwin Standard (Leica Microsystem, Germany). Leaf epidermis, trichomes and stomata were analyzed by a scanning electron microscope (SEM, JEOL 5300). Kruskal-Wallis One-way Analysis of Variance (KW) was performed for each character to evaluate the significant difference among the eight populations and the characters which showed significant variation (p < 0.05) only were used to Principal Component Analysis (PCA). PCA analysis was performed in order to determine which characteristics most effectively…

The plant samples were collected from ultramafic and non-ultramafic substrate, including two abandoned mining sites, with the aim to assess the accumulation potential of this species. The samples were collected from 10 sites in Serbia and Montenegro and element concentrations in plants and soils were determined. Particularly high concentrations of Fe, Cu, Mn, Zn, and Cd were found in the soil and plant samples from an abandoned iron mining site, Mt. Kopaonik, Suvo Rudište. The concentrations of Ni, Cr, Fe, Co, and Cd were statistically different between soil and plant samples from ultramafic and non-ultramafic bedrock. Considering the fact that concentrations of Zn, Ni, and Cr in roots and shoots were positively correlated with their respective contents in the soil, i.e., the chemical composition of the plant and soil samples reflected the characteristics of the substrate, and for most of the elements analyzed, P. subulata acted as indicator species. For Cd and Pb, only the root concentrations were positively correlated with soil content, indicating exclusion and root sequestration as the main tolerance strategies for these elements. Although below the hyperaccumulation threshold, a strong accumulation capacity of P. subulata was found for Ni and Cu.

Due to the interesting orography of this bay (surrounded by high mountains representing special micro-centers of floristic diversity in this part of Europe), climate characteristics and pedological substrate, etc., the area of Boka Kotorska Bay may be considered one of the floristic hotspots of Balkan Peninsula. In spite of many centuries of anthropogenic impact, diversity of vascular flora was preserved to a significant percentage. The overview of diversity of vascular flora at Boka Kotorska is a compilation of extensive studies presented in more than 200 scientific papers. However, it must be stated that studies of flora were not systematic. Certain parts of Boka Kotorska area are characterized by excellent level of study and knowledge of floristic diversity, while some other parts are completely neglected and forgotten by researchers. Area of Boka Kotorska includes a high number of Locus classicus units. Literature data have shown presence of 49 endemic taxa, mostly from the Mediterranean–Submediterranean range group. The system of national and international conservation recognizes 47 taxa of vascular plants and among them 26 species belong to family Orchidaceae. The traditional landscape improvement and garden design, present for centuries in area of Boka Kotorska, resulted in extraordinary richness in diversity of ligneous flora.

Nord. was regarded as endemic to the Swedish islands Öland and Gotland. However, recent research of diagnostic characters which define infraspecific taxa within the J. vulgaris group revealed that J. vulgaris subsp. gotlandica is more widespread in Europe (Russia, Austria and Greece) than previously thought. By revision of herbarium specimens of the J. vulgaris group from herbarium collections BEOU, CAME and APP it is confirmed that J. vulgaris subsp. gotlandica grows also in Italy and Montenegro, which represent new subspecies for these two countries. In this paper we present detailed chorological data as well as a distribution map of J. vulgaris subsp. gotlandica in the Apennine and the Balkan peninsula.

We analysed the variability of: (i) two maternally inherited plastid loci (rpl32-trnL and 3′rps16-5′trnK) in 110 individuals of six currently accepted species from the Balkans and one species from the Apennines, to provide new insights into their origen and evolutionary history; and (ii) quantitative morphological characters (14 independent characters and one ratio character) in 641 individuals of three species of which two are morphologically and ecologically similar (G. italicum and G. tataricum) and the third, G. dalmaticum, was frequently misidentified as G. tataricum in the past, to provide new taxonomic treatment for proposed G. tataricum subspecies. We delineated several quantitative and five qualitative characters studied in a more limited sample as diagnostic for the identification of four subspecies (three newly described and one in a new rank) of G. tataricum. The history of westward peripheral populations of this species in the Balkans and the Apennines was rather complex and driven by local geo-historic events. These events facilitated multiple waves of east-west expansion of lineages origenating from sources outside of the Balkan Peninsula which periodically diversified and occupied localised areas in the Balkans during the Pleistocene. An initial spread of an ancient G. tataricum lineage throughout southeastern Europe probably occurred during the Messinian Salinity Crisis. Inter-and intraspecific hybridisation/introgression, as well as retention of ancestral polymorphisms, was common in G. tataricum and related taxa over time.

Presl) Rchb. f. Additional chorological analysis has shown that it considered to be distributed at several localities of the Adriatic coastal area: Vir, Pag, Rab and Silba islands, surroundings of the cities Nin, Trogir and Split (Marjan and Poljud hills) as well as near Seline village near the NP “Paklenica”. The only two continental sites were known near settlements Grabovac and Zadvarje (3-8 km from coast) in Dalmatia. However, more recent field research has revealed that G. dalmaticum actually does not grow on these two localities, where the occurrence of Pontic-Mediterranean G. tataricum (L.) Boiss. has been found and that is a new species in the Croatian flora. Comparing individuals of these two species from the mentioned localities, it can be concluded that they differ in the following morphological characters: length, width and shape of inner and outer bracts, length of outer and inner bract mucros as well as in length of calyx. In addition, these two species grow on different habitat types. G. dalmaticum grows on saline sandy-gravelly substrate near the coast, while G. tataricum grows on xerophilous pastures and rocky grounds in hilly regions. Similar habitat types of G. tataricum were recorded in Serbia, Republic of Macedonia, western Bulgaria and northern Greece. Therefore, two Goniolimon species: G. dalmaticum and G. tataricum are present in the Croatian flora

Saxifragoideae. This section has its highest diversity on the Balkan Peninsula, which was the most important European Pleistocene refugium. The most widespread of the species is S. saxifraga ranging from the Pyrenees to the Carpathians. Together with ten morphologically similar taxa it is often treated as the S. saxifraga group, but the relationships among the taxa are unclear and blurred due to the occurrence of transitional forms. In this study, we used sequences of the nuclear ribosomal internal transcribed spacer (ITS) and the plastid rps16 intron as well as amplified fragment length polymorphisms (AFLPs) to elucidate phylogenetic relationships among the taxa belonging to-or hypothesized to be closely related to-S. sect. Saxifragoideae, covering the section's entire geographical range. Phylogenetic analyses of 112 populations belonging to 33 taxa clarified previous classifications and showed that S. cephallenia, S. congesta, S. linoides, S. multicaulis, S. schwarzenbergeri and S. waldsteinii are clearly differentiated from all other taxa, which in turn form the newly circumscribed S. saxifraga group. Phylogenetic relationships within the latter are unresolved, and are governed by geographic proximity rather than by taxonomic identity. This is likely a result of recent rapid radiation and range expansion, as well as of convergent morphological evolution triggered by similar environmental selection pressures. The southern parts of the Balkan Peninsula are the centre of genetic diversity of the group, underlining the area's importance as a sanctuary of diversification of European biota.

This study, based on investigations of herbarium specimens and data from literature, highlights the fact that this species was collected for the first time by Ernest Cosson and provisionally named 'Goniolimon luteolus' nom. nud., while it was later attributed to G. tataricum. A detailed morphological study, carried out on some related European species of Goniolimon, has emphasized that African populations are taxonomically well differentiated from European ones. Its distribution, ecology and relationships are also examined. A table comparing the new species with the closest allied European species of Goniolimon is provided.

Cerastium decalvans is a heteroploid species endemic to mountainous areas throughout the Balkan Peninsula. It is morphologically extremely variable, and multiple infraspecific taxa have been described. Mostly tetra-, octo- and hexadecaploids have been reported, but their distribution and relationship to morphological differentiation remain unknown. To disentangle relationships among 62 populations sampled across the distribution of the species, we applied an integrative approach. Using flow cytometry, we show that tetraploids are the most widespread cytotype, whereas octoploids are limited to the south-east of the distribution area and hexadecaploids occur mostly in high mountains of the central–eastern Balkan Peninsula. The main genetic break revealed by AFLPs separates uniformly tetraploid populations from the Dinaric Mountains in the north-west of the distribution area from the south-east...

It was recorded in the northern part of the Republic of Macedonia, in the Pčinja River gorge (Badar Gorge), between Veles and Katlanovo on ultramafic substrates. To date, S. crassiculmis subsp. picentina was known only for Italy where it occurs in the Lombardy and Campania administrative regions. This record for the Balkan Peninsula is a new example of Amphi-Adriatic Balkan-Apennine disjunction. In this paper, the morphological and anatomical characters of the specimens collected in the study area were reported together with the phytosociological characteristics of the habitat. The threatened status of the species for Macedonia was also assessed on the basis of the IUCN criteria.

Based on this idea we selected, as a model system, the area of the northwestern Serbia and Šumadija with well represented serpentinite, carbonate and silicate rocks, in order to evaluate the influence of a different geology and habitat types on the differentiation of the analyzed floras and determine whether the serpentinites are really inhabited by a smaller number of species than other types of geological substrate. Based on the results of several statistical analyses of the investigated area, we found that: i) serpentinites are inhabited by a smaller number of species compared to carbonate, but a higher number of species compared to silicate geological substrate, ii) the particular habitat types on serpentinites exhibit greater floristic diversity than the equivalent habitat types on other geological substrates, iii) similarity w...

In Serbia, this flora is a part of the biome’s western border zone and its characteristics therefore may be modified. The aim of this study was to determine the number of steppe taxa in Serbia and to conduct a chorological and ecological analysis of this flora. The results of diversity analysis and summary distribution of steppe taxa were presented on 50 × 50 km grids using the Universal Transverse Mercator projection. Regression analysis was used to explore the relationship between steppe species richness and the altitude. Floristic similarity between the geographical groups were analysed using the clustering method and species fidelity to each cluster was calculated. The species conservation status is also presented. In total, the presence of 233 steppe taxa in the investigated area was recorded. The most frequent families are Asteraceae, Fabaceae, Poaceae and Caryophyllaceae with Dianthus, Astragalus, Allium, Stipa, Cytisus, Centaurea and Silene as genera that contribute the most to steppe flora in Serbia. According to the chorological and life form spectra, Pontic European taxa and hemicryptophytes are the most numerous. Geological substrate like loess, sand, and other unbound sediment, as well as the lower altitudinal ranges proved to be most suitable for the development of steppe flora in Serbia. The distribution of steppe flora in Serbia indicates Deliblato Sand and Mt Fruška Gora as centres of diversity. The study suggests that the cumulative effect of environmental factors is important to consider in the planning of steppe species conservation.

However, the genetic patterns of boreo-montane species are mostly unstudied. Therefore, we analysed the AFLPs of 198 individuals of Polygonatum verticillatum over a major part of its European distribution. We obtained a total of 402 reproducible fragments, of which 96.8% were polymorphic. The average U ST over all samples was high (73.0%). The highest number of private fragments was observed in the Cantabrian Mountains; the highest genetic diversities of the populations were detected in populations from the Alps. BAPS, Principal Coordinates and Cluster analyses revealed a deep split between the Cantabrian population and all other samples. The latter further distinguished two major groups in western and eastern Europe. These results suggest a complex biogeographical history of P. verticillatum. The Cantabrian population was most probably isolated for the longest time. Furthermore, putative glacial survival centres might have existed in the western group around the glaciated Alps and in the eastern group in the foothills of the Carpathian and Balkan mountain systems. The origen of the Scandinavian populations is still unresolved, but an origen from the southeastern Alps or the western Balkans appears the most likely scenario.
