    Opis:
    W niniejszej pracy oceniono zróżnicowanie składu gatunkowego drzew i krzewów porastających teren Elektrowni „Pomorzany” w kontekście weryfikacji doboru tych gatunków do lokalnych warunków miejsko-przemysłowych. Stwierdzono występowanie 761 drzew reprezentujących 34 gatunki. Największy udział w strukturze gatunkowej drzew (18%) stanowiły topole (Populus alba, P. nigra, P. canadensis, P. tremula, P. simonii). Krzewy na badanym terenie występują w ilości 1497 egzemplarzy, reprezentujących 27 gatunków. Znaczący udział w strukturze gatunkowej krzewów na tym terenie (19%) odgrywają róże (Rosa sp.). Zieleń zakładową Elektrowni „Pomorzany” należy uznać za urozmaiconą i dobrze skomponowaną, z właściwym doborem gatunków drzew i krzewów. Bieżąca pielęgnacja staje się jednak utrudniona w związku z narastającym zagęszczeniem, szczególnie krzewów, oraz zacienieniem spowodowanym silnym rozwojem koron drzew.
    The diversity of tree and shrub species growing in the area of the „Pomorzany” Power Plant is presented in this paper. The present research also estimates the proper choice of species in accordance to the local, industrial conditions. In the studied area there were 761 trees of 34 different species. The biggest part in the typical structure of trees (18%) was taken by Populus alba, Populus nigra, Populus canadensis, Populus tremula and Populus simonii. In the researched area there were 1497 shrubs of 27 different species. Rosa sp. had a significant quota in a typical structure of shrubs in that area (19%). The research indi-cated that the industrial green in the area of the „Pomorzany” Power Plant was diversified and well composed with a proper selection of trees and shrubs species. However, a present care becomes difficult because of the increasing density especially of shrubs and also because of shadowing caused by a strong evolution of tree crowns.

    Opis:
    European white oak species (Quercus sect. Quercus) are known to share a substantial part of their nuclear and cytoplasmic genomes as a result of extensive interspecific hybridization and introgression. We studied natural populations of three species distributed in Slovakia, namely Q. robur, Q. petraea and Q. pubes- cens, which are largely sympatric but have contrasting ecological requirements, using a combination of leaf morphometry, neutral nuclear microsatellite markers (nSSR) and potentially adaptive amplified fragment length polymorphisms (AFLP). Bayesian analysis of population structure relying on nSSR revealed that the degree of admixture was relatively low in Q. robur but higher in Q. petraea and Q. pubescens. The inferred Q. robur ancestry closely correlated with morphometric scores of the canonical discriminant analysis based on 13 leaf traits, while for the other two species the correlation was much weaker. We identified two AFLP fragments associated with climatic variables, mainly with air vapour pressure and characteristics of temper- ature regime at the sites of origin. These associations indicate that climatic adaptation is the mechanism driving interspecific divergence and maintaining integrity of white oak species.

    Opis:
    The argument from design, the proof of the existence of God from the design-like nature of the world, especially organisms, dates back to Plato in the Phaedo. Despite problems, namely the existence of evil, thanks particularly to Archdeacon William Paley’s Natural Theology, the argument was highly influential in British thought at the beginning of the nineteenth century. Charles Darwin’s theory of evolution through natural selection, as given in his Origin of Species, challenged this hegemony. It is important to note what Darwin did and did not challenge. He accepted fully that or ganisms are design-like; that, in the language of Aristotle, they show “final causes”. Natural selection explains why this is so. He denied that this feature demands the hypothesis of a designing consciousness, namely God. Darwin was an agnostic, so did not want to deny the existence of God as such. Rather, he thought that the argument failed to prove this. Darwin’s conclusion has led to much subsequent discussion. Generally, however, the world — including Christians — agrees with him. In the words of the English theologian John Henry Newman, as a Christian one can accept that God explains design, one cannot accept that design proves God.

    Opis:
    The juvenile height growth of Norway spruce (Picea abies (L.) Karst.) was studied in 1095 spruce provenances included in the IUFRO inventory provenance test of 1964/68. Trees growing on the experimental site established in Krynica in the Beskid Sądecki Mts. (Carpathians) were measured at ca. 3-year intervals in the period 1969-1988, from the age of 6 years (i.e. 2 years of planting) to 25 years. The variability of tree height in this spruce population was assessed on the basis of the means expressed in units of standard deviation, calculated for each provenance and each geographical region of Krutzsch in successive years of measurement. Using the standardised units made it possible to characterise the dynamics of spruce growth in provenances from 95 geographical regions representing the whole European range of the species. The effects of geographical region, tree age and their interaction on the variability of height growth within this range were estimated using multi-way analysis of variance with replicated measurements. The regions showing similar spruce growth trends were grouped by using hierarchical cluster analysis. The results on the juvenile dynamics of height growth showed that spruce provenances from various geographical regions of Krutzsch differ significantly in their genetic reactivity. Based on this, several groups of regions were identified: (1) regions with average or weak but stable spruce growth characterised by no significant effects of age or genotype × age interaction in the whole measuring period, or regions with height growth improving with age; (2) regions of spruce provenances constituting a selection elite, with very good height growth in the whole measuring period or in its later part, characterised by no G × A interaction; (3) regions with varied genetic reactivity of height growth dynamics in the juvenile period, and regions of Scandinavian populations with poorest height growth in the whole measuring period. The studies proved that spruce provenances from the regions of Štiavnické Pohorie, Low Tatras (Slovakia), Masurian Lakeland, Augustów Lakeland, Podlasie, Silesian Beskid Mts., Beskid Żywiecki Mts. (Poland), Jutland (Denmark), Bihor Mts., Transylvania, and Eastern Carpathians (Romania) have a high selection value.
