    Opis:
    The paper analyses the distribution and occurrence conditions of Loiseleuria procumbens in the Spanish Pyrenees. The species represents a typical arctic-alpine element in the flora of Europe. In the Pyrenees it reaches its southernmost European localities. The Pyrenean populations of the species are not numerous in the majority of the localities. L. procumbens occurs most frequently in the alpine and subalpine zones, at altitudes between 2100 and 2650 m, with a minimum at 1750 m and a maximum at 2900 m. It has been reported nearly exclusively in the siliceous substrata, and predominantly on the north-facing slopes, on the regosols and/or on flat tops of rocks. It forms its own communities, mostly included into the Loiseleurio-Vaccinion alliance, and rarely enters associations of the Festucion airoidis and Rhododendro-Vaccinion alliances. Its typical community, Cetrario-Loiseleurietum procumbentis, is found only in the eastern and central parts of the Spanish Pyrenees.

    Opis:
    The frequency of occurrence of abnormal, three- (or more) needle dwarf shoots of most southern and central European two-needle pine (Pinus) species were studied. No specimens with more than two-needle dwarf shoots were found in a population of P. nigra Arnold subsp. salzmannii (Dunal) Franco from the Iberian Peninsula and in two populations of P. uliginosa Neumann from the Sudeten Mountains in Central Europe. Single specimens were found within one population of P. pinaster Aiton from the Iberian Peninsula and among six populations of P. sylvestris L. from the Iberian Peninsula and Central Europe. Abnormal dwarf shoots mostly with three, but also four, five or six needles were found among 24 of 25 surveyed populations of P. mugo Turra and P. uncinata Ramond. The average frequency of specimens with at least one three-needle dwarf shoot was 24% for P. mugo and 20% for P. uncinata. The frequencies of occurrence varied significantly among studied populations and were highest in samples collected from the upper elevational range limits of the species in the mountains and near the northern limits of their ranges. The frequency of abnormal dwarf shoots in the same populations was significantly high in 2-3 consecutive years. Needles from three-needle dwarf shoots were not significantly shorter than those of two-needle shoots.

    Opis:
    The geographic distribution and occurrence conditions of Juniperus thurifera subsp. africana in Morocco were studied. The literature and herbaria data, together with field observations formed the basis of detailed maps of distribution of the species in the Middle and High Atlas and allow us to analyze its vertical distribution. The taxon occurs in the sub-arid and arid zones of the Middle and High Atlas with a separate population in the Anti-Atlas, mostly between altitudes 2000 and 2700 m, with an altitudinal maximum at 3400 m and a minimum at 1700 m. It forms forests in the area of about 30 000 ha. In many places of the High Atlas it is the only wood source for local populations. It is strongly endangered because of over exploitation of the wood, over pasturing and lack of seedlings and young specimens.

    Opis:
    The 153 taxa of trees and shrubs were reported from the Stołowe Mts. Two species (Betula nana and Erica tetralix) were reported probably by mistake,and 7 are now extinct (Arctostaphylos uva-ursi, Chamaecytisus ratisbonensis, Genista pilosa, Lembotropis nigricans, Rosa agrestis, Salix lapponum, Salix myrtilloides). The other 144 taxa of trees and shrubs were found in the natural and semi-natural site conditions. The 110 native taxa and 34 anthropophytes are forming the contemporary woody flora. The 44 native taxa belong to various local red data book categories (including extinct),the 63 are not endangered and next 10 are apophytes. A few altitudinal groups of species can be distinguished,which are characterized with specific reaction to the growth of the altitude of localities. The distinct limit in the altitudinal ranges of the woody species occur at elevation of 580-600 m. This altitude was considered as the limit between submontane and montane belts in the Stołowe mountains.

    Opis:
    Cerasus fruticosa is a rare and endangered plant species in Poland. In northern part of the country it occurs on scattered localities of relic, early Holocene (preboreal) character. Most of the species stands known from the end of 19th century have disappeared in the last decades. All data, revised in the field 40 years ago, were checked in 2000-2002. The species survived on 6 localities of 14 ones, confirmed in sixteenth. The hybridization between C. fruticosa and C. vulgaris is one of the main reasons of extinction of the first species. The floristic composition of plant communities with C. fruticosa was examined and compared with relevant literature. The regression of photophilous and thermophilous plant species, characteristic for associations with C. fruticosa and moderate invasion of synanthropic ones were observed.

    Opis:
    The natural population of yew in the Knyazhdvir Nature Reserve was described and its status has been analyzed. It was stated that more than 22 000 specimens of yew grow there and it is the most numerous population of the species in Ukraine. The most important factor for Taxus baccata occurrence there are the presence of calcium carbonate and humidity of the soils. The height and diameter structures of the population indicate that the population is in progress. The largest specimens in 1976 were of 12 m high and of 30 cm dbh. The natural regeneration is satisfactory. The increment of height of the yew was greater in the conditions of less density of the canopy of beech-fir stand under which the species grows.

    Opis:
    Genetic differences between two populations of P. uliginosa from Batorów and Węgliniec were assessed on the basis of 15 allozyme loci. The level of genetic differentiation between them was also compared with genetic differences among the three closely related pine taxa: P. uliginosa, P. sylvestris and P. mugo. A high level of genetic variation was found in both populations of P. uliginosa. The average (Na) and effective (Ne) numbers of alleles per locus amounted respectively to 2.47 and 1.50 in Węgliniec and to 2.67 and 1.52 in Batorów and the percentage of polymorphic loci was 80% and 87%, respectively. Close relationship between the three studied species were confirmed. The genetic differences between the two populations of P. uliginosa were substantial, as the Nei's genetic distance between the two populations (D = 0.040) was larger than between populations of P. sylvestris and between populations of P. mugo. The relatively high level of genetic differentiation between P. uliginosa populations may result from their isolation, small size and possibly different origin of these populations.

    Opis:
    The genetic diversity within and among twelve populations (379 individuals) of Pinus mugo from the Giant Mts., Carpathians and Alps was analyzed using ten chloroplast microsatellite markers. A stepwise mutation model (SMM) for microsatellite loci was used in order to estimate divergence between populations and provenances from three mountain ranges. High levels of genetic diversity and significant differentiation were found among the three population groups. The populations from Giant Mts., Carpathians and Alps were strongly differentiated between each other, while differences among populations within these massifs were much lower. The pattern of genetic structure observedin dwarf mountain pine can be characteristic in conifers with a disjunctive geographic distribution. The significant genetic structuring among isolated parts of the geographic range of the species may be a result of an ancient fragmentation andlong lasting geographic isolation between the Giant Mts., Alpine and Tatra populations of P. mugo.

    The intra- and interpopulational geographic variation of three distant populations of J. oxycedrus subsp. macrocarpa was examined biometrically on the basis of morphological key-characters of needles, seeds and cones. The shortest Euclidean distances were used in the agglomerative grouping of closest neighbourhood and discrimination analysis with principal component analysis (PCA) was performed to verify the south-north differentiation of the taxon in Italy. Most of the cone and seed dimensional characters are correlated. No significant correlations were found between cone and needle characters. The sampled populations differ only insignificantly from one another, while the intrapopulational variation is slightly higher. Cone length as well as seed number, width and thickness were significantly correlated with geographic latitude, while the other four characters are not. Differences in cone shape were observed between individuals, so that several morphotypes can be distinguished.

    Opis:
    Reconstruction of the glacial and postglacial history of a species, including life-history traits, provides valuable insights into the relationships between ecological and genetic factors shaping phylogeographic patterns. Clonality appears as a trait of high importance for survival in northern refugia. In the present study, the phylogeographic structure of 24 Alnus incana (grey alder) populations and clonal structure in seven populations were analyzed utilizing four microsatellites markers. Palaeobotanical data were collected and combined with the genetic results in order to support the possibility that this species survived in northern refugia. Our study indicated that: (i) Balkan populations are the most divergent, which likely reflects their long-term in-situ existence, (ii) Western Alpine populations are genetically different from other European populations, which corresponds with palaeobotanical data, suggesting that this region served as a refugium for this species, (iii) the macrofossil data indicate that the Scandinavian and northeastern Polish populations are likely derived from the refugia located in northern latitudes, (iv) Western and Eastern Carpathian populations form separate groups, which indicate that both regions could serve as refugia. Clonality was an important factor in allowing grey alder to survive in northern regions during the last glaciation. However, this mode of reproduction has also influenced the population genetic structure, as we noted rather low level of gene diversity, HE = 0.386 and low allelic variability, A = 3.8, in this species.

    Opis:
    Basing on repeated analyses of vegetation of the ‘Cisy Staropolskie im. Leona Wyczółkowskiego’ reserve near Wierzchlas (N Poland) it was found that frequency of species characteristic for Querco−Fagetea association increased at the expense of species typical for acidophilous and wet sites (Vaccinio−Piceetea, Quercetea robori−petraeae and Alnetea glutinosae, Phragmitetea classes respectively). Yew population decreased in number by almost 30%, while in case of other species this rate amounted from 18 to 80%. This points to natural process of decrease in number of trees related with their growth and ageing. Sex structure of Taxus baccata population (only 29% of females) turned to be very unfavourable. Although yew seedlings occur in great number, they die in vast majority during the wintertime. Low temperature connected with over−shadowing are probably the main reason of such small survival rate.

    Opis:
    Peat-bog pine Pinus uliginosa Neumann has become extinct or rare in many parts of Europe. We have investigated the levels of genetic variation and inbreeding in seeds collected from a highly endangered reserve of this species in Poland, using allozymes as genetic markers. Generally, a high level of genetic variation was observed. The mean expected heterozygosity was 0.376, while average (Na) and effective (Ne) numbers of alleles per locus were 2.45 and 1.67, respectively. Nevertheless, we have detected relatively low levels of outcrossing, and potential biparental inbreeding. The population-wide multilocus outcrossing rate was estimated to be 0.706 (±0.091), while the minimum variance mean of single-locus estimates was distinctly lower (ts=0.611). The estimates of outcrossing calculated for individual trees ranged widely from 0.051 to 1.017, indicating the complexity of outcrossing patterns. The investigated population of P. uliginasa from Węgliniec is small and surrounded by extensive forest stands of P. sylvestris. Our three-year records of phenological observations demonstrated that flowering periods for P. uliginosa and P. sylvestris overlap, allowing for cross-pollination. The possibility of P. uliginosa pollination by P. sylvestris creates a potential danger of genetic erosion of the P. uliginosa gene pool. Nonetheless, based on a species specific cpDNA marker we have found that among 533 seedlings of P. uliginosa there were only six seedlings carrying cpDNA marker specific for P. sylvestris, indicating that such hybridization seems to be rare.

    Opis:
    Pinus mugo occurs only in the highest mountain chains of the Ukrainian East Carpathians. The largest part of the species area covers the Chornokhora ridge and the highest ridges of the Gorgany. In the other mountains of Ukraine it does not form thicket on so large terrains. Vertically, most of localities are placed at an elevation between 1400 and 1900 m, with maximum at 2010 m in the Chornokhora and with minimum about 700–800 m. The latter stands were reported from the peat bogs, however, the most of them have been destroyed and do not exist now. The dwarf mountain pine forms the community of Pinetum mugo, formed exclusively on the substrata not containing calcium dioxide. The species is connected with northern exposures. The area of distribution of Pinus mugo has been strongly reduced during centuries and association Pinetum mugo transformed into pastures.

    Opis:
    The Cecilian pine (Pinus ceciliae) is endemic to Balearic islands (Spain). It is a small taxon, some- times treated as synonym of Aleppo pine (P. halepensis), to which is closely related, differing mainly with dense crown shape and upright branches. The other characteristics, which differ between P. ceciliae and P. halepensis concern the cone scale and needle length only. We examined biometrically needles of Cecilian pine from Mallorca (5 tress) and Menorca (9 trees) islands, and compared them to Aleppo pine populations rep- resented by 30 trees from each island. Each tree was represented by 5 needles, and they were studied with respect to 17 morphological and anatomical characteristics. We detected that needles of the Cecilian pine were smaller, but only when compared to the Aleppo pine from the same island. In general, this difference was also observed in the number of resin canals, number of stomata and stomatal rows. Interestingly, the proportions of the needle dimensions pattern were similar in both taxa. In conclusion we stated the results support the taxonomic rank of Cecilian pine as a variety, Pinus halepensis var. ceciliae (Llorens & L.Llorens) L.Llorens, Fl. Països Catalans, 1: 197 (1984)

    Opis:
    We present a study of the distribution, ecology and conservation status of Cupressus atlantica, an endemic tree of the High Atlas (Morocco). The main populations of this species grow in a reduced area along the N’Fiss valley in the Central High Atlas and are gradually receding. Particular populations are increasingly fragmented and the total area covered by the cypress woodland has decreased to less than a third of the surface occupied in the 1930s. Overgrazing reduces the woodlands’ regenerative capacity, and the exploitation of the wood, linked to traditional uses by the rural society of the N’Fiss valley, directly reduces the number of trees. Great efforts being made to protect the species by the Haut Commissariat aux Eaux et Forêts are having some effect in recent years.

    Opis:
    The biometrical comparison of nine populations of Juniperus phoenicea from the western part of the species geographic range was the aim of the present study. Seven features of the cones and seeds, two of the shoots and leaves and eight proportions were studied biometrically and analysed using statistical methods. Two of analyzedpopulations, supposedto be representatives of J. phoenicea subsp. phoenicea, are closely related each other. The seven other populations representing J. phoenicea subsp. turbinata, appearedmuch more variable andd ifferedeach other at higher level. The results confirm the biochemical andgenetic differentiation of the species, however, it can partly be an effect of smaller number of comparedpopulations of subsp. phoenicea. The individuals included into each of distinguished subspecies are different and only a few individuals of subsp. turbinata from the Atlantic coast in Portugal were foundto be joinedinto the group of subsp. phoenicea. The differences between populations of subsp. turbinata are higher than between those of subsp. phoenicea. The most distant population of the subsp. turbinata, from Cabo Rizuto in Italy appears also the most different from all the other. It results probably from the isolation for a longer time.

    Opis:
    The intra- and inter-population variation in three populations of Juniperus excelsa, two from Crimea and one from the Balkan Peninsula, were analyzed biometrically. Fourteen morphological characters of cones, seeds, shoots and leaves were used. The number of seeds per cone appears to be the most variable character. The others were more stable. Differences among particular individuals within the samples were slight, as well as between populations compared. The Crimean samples were very close to each other, while the more geographically distant sample from the Balkan Peninsula appears also to be morphologically more separate. This suggests that the Balkan populations originated from another Pleistocene refugium. The Crimean populations did not show the reduction of variability, which could have resulted from their geographical isolation and their considerably restricted numbers of individuals.

    Opis:
    The aim of the present study was biometrical comparison of three Iberian populations of Juniperus phoenicea, represented by the subsp. turbinata and subsp. phoenicea. Eight features of the cones and seeds, two of the shoots and leaves were studied. The biometrical analysis of three distant populations of J. phoenicea shows great taxonomic distances among them. Two of them, representatives of J. phoenicea subsp. turbinata, are closer related each other than to the third, which represents J. phoenicea subsp. phoenicea. These results confirm the genetic differentiation of the taxons and also the biochemical and morphologic division of them. Nevertheless, the distances between particular populations are so great that more resemble the distances between species than between subspecies.

    Opis:
    Rhododendron ferrugineum occurs in the mountains of the Central Europe with large disjunction in geographic range between Pyrenees and Alps and between Alps and Sudetes. We expect that these discontinuities in the species occurrence should involved their phenotypic differentiation, similar as described on the studies of molecular markers. The aim of the study was verification of phenotypic differences between the species populations from the Pyrenees, Alps and Sudetes. We examined characters of leaves and capsules from 13 populations, each represented by 25–30 individuals, using ANOVA, discrimination analysis, principal components analysis and agglomeration on the closest Euclidean distances. Every from examined characters of leaves and capsules except of apex angle of a capsule valve and capsule valve shape differentiated between populations at P≤0.001. Despite, range of character variation differentiating even at the highest level overlapped between populations. The analysis of discrimination, principal component analysis and agglomeration gave similar results indicating differences between populations from Pyrenees, Alps and Sudetes. However, the differences between individuals did not allow distinguish regions. The morphological characteristics of the leaves and capsules allowed to distinguish among populations of R. ferrugineum from the Pyrenees, Alps and Sudetes, and the pattern of their phenotypic differentiation was similar to that described based on genetic markers. The relict population from the Sudetes is phenotypically more similar to the populations from the Pyrenees and the Western Alps than to the spatially closest populations from the Eastern Alps.

    Opis:
    Zelkova carpinifolia is a relict tree occurring in refugial zones of south-western Eurasia. The main aim of the study was the biometrical comparison of the leaf characteristics of the species sampled in three regions of Transcaucasia. We aimed to test the hypotheses that (1) leaves from vegetative (L) shoots would be larger and more variable than those from fertile (S) shoots, (2) the leaves from the same shoot type express geographic patterns of morphological differentiation, similar to pattern described for genetic markers and (3) to verify the systematic position of Z. hyrcana and Z. carpinifolia subsp. yomraensis. The plant material was collected from 5 populations of Z. carpinifolia, one of Z. hyrcana and one of Z. carpinifolia subsp. yomraensis. The total 1482 leaves, 713 from L- and 769 S-type were measured using 26 characters. Our results show very high level of differences between leaves from the L- and S-type of shoots. The majority of leaf characters did not reveal dependence neither on geographic latitude, longitude and altitude nor on the basic climatic data. The results of multivariate analyses of S leaves revealed three group of populations, namely from (1) Colchis, (2) eastern Caucasus (3) Talysh. Thus, our biometric analyses revealed similar pattern to the haplotypic differentiation of Z. carpinifolia detected using chloroplast markers described in the literature. We did not detected significant differences in the leaf characters between supposed Z. hyrcana and/or Z. carpinifolia subsp. yomraensis, when compared to Z. carpinifolia, thus not confirming their separate taxonomic status.

    Opis:
    Pinus sylvestris (Scots pine) and taxa from the P. mugo (mountain pine) complex hybridize in contact zones producing morphologically-intermediate fertile hybrids. However, the hybrid specimens sometimes express only the P. sylvestris phenotype. Such cryptic hybrids were detected among P. sylvestris and P. uliginosa in the western part of Błędne Skały in the Stołowe Mountains, where the pines grow on the tops of sandstone rocks and phenotypically resemble P. sylvestris, P. uliginosa, and P. mugo. Hybrids with the P. sylvestris phenotype could be potentially present in other relic populations of this species in these mountains. During the present study, the hybrids were identified only in the area of Błędne Skały based on chloroplast and mitochondrial markers, morphological differentiation of various needle and cone traits, and phenotype assessments of the trees during sampling. these hybrids included three cryptic hybrids of P. sylvestris × P. mugo with the P. sylvestris phenotype and one displaying the phenotype of P. uliginosa. The other populations analyzed represented Scots pine with no evidence of hybridization with P. uliginosa and/or P. mugo. Biometric data on the cone and needle morphology also suggest possible hybridization within the P. mugo complex on Błędne Skały. The results indicate that hybridization takes place in this population but not in neighboring populations despite the possible connection by pollen-mediated gene flow.

    Opis:
    Divergence in genetic as well as phenotypic structures can be expected in species with disjunctive geographic ranges and restricted gene flow among isolated populations. Dwarf mountain pine has such a disjunctive geographic range in the mountains of Central Europe. We hypothesised that populations of Pinus mugo from the Giant Mts. differ from Alpine and Carpathian populations to a greater extent than differentiation within these regions; furthermore, these differences would be detectable at both the genetic and phenotypic levels. To verify this hypothesis, the diversity and differentiation within and among eleven populations from the Giant Mts., Carpathians and Alps were analysed using 19 isozyme isozyme loci, 17 needle and 15 cone morphological characters. Moreover, the data on 10 chloroplast microsatellites used in the previous study, were reanalysed. The differences between the three regions were greater than among populations within them. The microsatellites and isozymes clearly differentiated between regions, while in the multivariate analyses of cone and needle characters the Alpine and Carpathian populations were intermingled but distinct from those sampled in the Giant Mts. The significant genetic structuring among regions may result from an ancient fragmentation and long lasting geographic isolation between the Giant Mts., Alps and Tatras. The populations from the Giant Mts., the northernmost within the geographic range of P. mugo, presented lower level of genetic variation then those from the Alps and Carpathians. The pattern of genetic structure observed in dwarf mountain pine may be characteristic of wind-pollinated trees with a disjunctive geographic distribution

    Opis:
    The relict tree species Zelkova abelicea and Z. sicula (Ulmaceae) occur in Crete and Sicily, respec- tively. Zelkova abelicea grows in approximately 40 localities in the mountains of Crete, while Z. sicula has been found in only two stands in Sicily. We compared 25 morphological characters of the leaves of both species and used statistical methods (Tuk- ey’s test, discrimination analysis, principal component analysis, agglomeration) to reveal the differences between these two species, their relation to Z. carpinifolia (the third Zelkova south-west Eurasian species), and between the leaves from different shoot types. Our study represents the first comparative biometric analysis of the three Zelkova species localized in the western edge of the current geographic range of the genus. We found that the species differed from each other both, in terms of leaf form characters and level of leaf variation. Zelkova carpinifolia was clearly differ- ent from Z. abelicea, while the two populations of Z. sicula, SIB and SIA, were more similar to Z. carpinifolia and Z. abelicea, respectively. The latter finding supports the results of recent molecular studies suggesting the hybrid origin of Z. sicula. Zelkova abelicea, Z. sicula and Z. carpinifolia differ each other in the leaf characteristics and level of phenotypic variation.

    Technologia napawania laserowego polega na wykorzystaniu wiązki laserowej celem precyzyjnego nałożenia warstwy materiału o podwyższonych właściwościach na podłoże. Szczególne zainteresowanie budzi ona w branży lotniczej. Odpowiednie przygotowanie procesu wiąże się z wykonaniem testów symulacyjnych z wykorzystaniem modeli przepływu dwufazowego oraz interakcji wiązki laserowej z materiałem. Następnie zostają wyznaczone ścieżki ruchu głowicy przy użyciu dedykowanych narzędzi CAD/CAM. W ramach analizy technologii napawania laserowego dla zastosowań branży lotniczej przedstawiono nakładanie powłok funkcjonalnych, będących alternatywą dla chromu elektrolitycznego. Przeanalizowano również metodę regeneracji wierzchołka łopatki turbiny silnika odrzutowego. Zaprezentowano też możliwości obróbki hybrydowej w wytwarzaniu przyrostowym tytanowych komponentów lotniczych oraz metodę monitorowania temperatury celem jakościowej kontroli procesu.
    The laser cladding technology consists of the use of laser beam for precise deposition of a material layer with enhanced properties to the substrate. Therefore it finds special interest in the aviation industry. Appropriate preparation of the process involves performing simulation tests using two-phase flow models and laser beam interaction with material. Subsequently, the laser head movement paths are determined using dedicated CAD/CAM software. In the analysis of laser cladding technology applications for the aviation industry, the deposition of functional coatings, being an alternative to electrolytic chromium, was presented. Secondly, the repair of turbine blade tip was also analyzed. Moreover the capabilities of hybrid laser cladding technology with machining for the additive manufacturing aviation components made of titanium alloys were presented, as well as the method of temperature monitoring for the purpose of qualitative process control implementation.
