    Opis:
    Provenance trials were designed to analyse the quantitative responses of tree species to environmental variables found in different experiment location. However, we have still limited knowledge how natural and artificial selection affects genetic variation of the species populations gather in such experimental sites. We have used bulked DNA-based RAPD and ISJ analysis to investigate genetic diversity and differentiation of Scots pine populations from two Polish locations of IUFRO 1982 provenance trial placed in Kórnik and in Supraśl. Applied categories of DNA markers differed in terms of revealing genetic diversity of the species. Ten RAPD primers applied in the study yielded a total of 75 bands, of which 21 (28%) and 15 (20%) were polymorphic in Kórnik and in Supraśl, respectively. Six ISJ primers revealed 42 bands of which 4 (9.52%) and 14 (33.3%) were polymorphic in Kórnik and in Supraśl, respectively. The genetic diversity and differentiation was low, as expressed by He=0.071 and He=0.085, and by genetic distance values which ranged from 0.0 to 0.240 (on average 0.081) and from 0.017 to 0.188 (on average 0.094) for Kórnik and Supraśl, respectively. Location of provenance trial appeared to have a significant influence on revealed level of genetic polymorphism and pattern of interpopulation differentiation. However, genetic structure found for analysed Scots pine provenances from IUFRO 1982 in Kórnik was also confirmed for Supraśl experimental site. In the light of available data we also discussed the influence of historical migration routes and gene flow on observed genetic variation of the species.

    Opis:
    We investigated the phenotypic variation of five morphological needle characters of Scots pine (Pinus sylvestris L.) in three populations. Two of the populations occurred in bogs and the third one formed a degraded fresh pine forest showing some features of a dry pine forest. The greatest variation was found in characters a (needle length), b and d, denoting the number of stomatal rows respectively on the convex and flat sides of the needle. Conversely, characters c and e (average number of stomata per 2 mm of needle length on the convex and the flat side of the needle) were stable, with little interindividual variation. The two bog populations and the dryland population exhibited different sets of character correlations. The interpopulation differentiational detected on the basis of morphological character expression was markedly influenced by both the different edaphic conditions, and the distinct genetic structure of the studied populations.

    Opis:
    The differentiation among three populations of Pinus sylvestris of the Tatra National Park (TNP); Łysa Skała, Siwarowe Pańskie and Wielkie Koryciska has been investigated with regard to eight anatomical traits of needles. These populations were compared to a lowland population of Tuchola Forests. Five analyzed traits: the thickness of epidermis with cuticle, the mean of width of three epidermis cells, the width of needle cross-section, the height of a needle cross-section and the ratio of height to the width of a needle are characterized by a variation coefficient not exceeding 10%. Variation coefficients for the remaining traits: the number of resin canals, the distance between vascular bundles and a Marcet coefficient, range between 15.04 – 24.95%. The needles of the lowland population (Rzepiczna) turned out to be the widest as well as the thickest and with the biggest distance between vascular bundles. The Tatra populations of P. sylvestris have a considerably thicker cuticle together with epidermis compared with the lowland population of Tuchola Forests. None of the individual traits differentiate the populations which have already been regarded as distinct – Łysa Skała, found in the eastern part of the TNP and Wielkie Koryciska, from its western part. However, having carried out a discriminant analysis and Mahalanobis distances, the differentiation of the Tatra Scots pine in relation to its geographical location was reported. The individual character of P. sylvestris found in the eastern and western parts of the Tatra National Park might be a result of their different origin in the last glacial period.

    Opis:
    To evaluate the geographic variability of Pinus sylvestris populations seven morphological traits of needles of pines from IUFRO 1982 provenance trial have been analyzed. The studied populations originated from northern (>55°N in Russia, Sweden and Latvia), central (55-47°N in Poland, Germany, Belgium, France, Slovakia) andsouthern (<47°N in Hungary, Bosnia, Montenegro andTurkey) European ranges of Scots pine. The analyzedprovenance trial experimental areas were locatedin Kórnik (western Poland) andin Supraśl (north-eastern Poland). The greatest variation was found in needle length and number of stomata rows on the flat and convex side of a needle, whereas number of stomata per 2mmof needle length on flat and convex side of a needle was stable, with minor interpopulational variation. Biometrical analyses revealed a significant population × location interaction anda geographical pattern in interpopulational differentiation in both experimental sites, with the northern andsouthern European Scots pine groups of provenancesdiffering significantly from the group of central origin. The results obtainedare compatible with previous results of studies on provenance variability of the Scots pine from IUFRO 1982. In the light of available data, the influence of the Balkan glacial refugia of Pinus sylvestris on a present genetic diversity of this species in Europe and the reconstruction of Scots pine migration routes after the last glacial period are discussed.

    Opis:
    The aim of this study was to characterize the turfosa form of Pinus sylvestris from the Gazwa peat bog reserve in terms of 16 anatomical needle traits and to determine whether pines with a typical morphotype inhabiting the peat bog have been so successful thanks to hybridization with the unique tufosa ecotype. Investigations were conducted on three phenotypic groups of Scots pine growing in the peat bog. The first two groups consisted of 30 tufosa trees at the age of 117-217 years and 20 trees at the age of 30-85 years. The third group consisted of typical pines represented by 10 trees at the age of 20-55 years. In total 30 trees of typical pine, surrounding the peat bog, at the age of 100-150 years served as outgroup. Descriptive statistics, analysis of variance with the F test, Tukey's test, and a number of multivariate analyses were used to estimate differences between the studied groups of trees based on 16 anatomical needle characteristics. The old turfosa form from the Gazwa reserve proved to be a unique and relict peat bog pine, as it was shown by the differences in 10 analyzed needle traits in comparison to pine with a typical morphotype growing in the areas surrounding the peat bog. The young typical pines have adapted to conditions found in the peat bog owing to hybridization with the turfosa forms. The young turfosa trees differed from the old turfosa trees and also they have probably been of a hybrid origin. The old turfosa form from the Gazwa reserve is a threatened ecotype due to its hybridization with pines from the population surrounding the peat bog.

    The physical properties of particles and phasesare considered in connection with their description by means of the deformation of space-time. The analogy between particle trajectories and phase boundaries is discussed. The geometry and its curvature is related to the Clifford algebraic structure whose construction in terms of the theory of deformation leads to the expected solutions for correlation functions referring to spectroscopy and scattering problems. The stochastic nature of space-time is reflected by fluctuations of distances and time intervals.

    Opis:
    Introduction. The dynamic rise of alcohol consumption in adolescents is a matter of serious concern, requiring frequently updated monitoring. By such means, it is possible to optimise preventative measures for dealing with this problem. Objective. To estimate the magnitude/amount and frequency of alcohol consumed by middle and high school pupils in Poland, including the circumstances when alcohol was first drunk. Materials and Methods. A randomised survey was performed throughout Poland on middle school (junior high school) pupils, (n=9360) in 2009, followed by both middle and high school pupils in 2011 (n=7971). The questionnaire was devised by the Polish Chief Sanitary Inspectorate (GIS). Results. A strikingly sharp increase in alcohol consumption (29%) was observed in subjects between 2009 – 2011. In the latter year, 1 month prior to survey, respectively, 50% and 71% of middle school and high school pupils drank alcohol, and correspondingly, 36% and 63% of these pupils ever became intoxicated/drunk. Conclusions. 1) Adolescent alcohol consumption increases with age and is highest in girls. Monitoring as well as in-depth analysis thus becomes necessary. 2) Systematic monitoring and analysis of changing healthy lifestyle behaviour should be used for taking the necessary corrective action. This should happen concurrently and consist of planned health education programmes, including health promotion.
