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:
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

Principal Component Analysis
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:
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 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 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:
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:
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.
