Opis:
W odpowiedzi na tekst Michała Chaberka, będący polemiką z moim stanowiskiem w kwestii teistycznego ewolucjonizmu, zwracam uwagę na kilka kluczowych zagadnień dotyczących filozofii i teologii arystotelesowsko-tomistycznej w kontekście teorii ewolucji, oraz wykazuję pewne nieścisłości i błędy w argumentacji mojego adwersarza. Definiując kluczowe aspekty terminu „stworzenie” w ujęciu Tomasza z Akwinu podkreślam, że zmiany ewolucyjne należą do Boskiego gubernatio, a nie creatio. Przedstawiam także nieco bardziej wnikliwą analizę zagadnienia dotyczącego konieczności bezpośredniej Boskiej interwencji w powstaniu nowych gatunków. Przechodząc do zagadnień stricte metafizycznych poruszam kwestie definicji substancjalizmu arystotelesowsko-tomistycznego, analogicznego charakteru statusu bycia substancją, oraz alternatywnej systematyki organizmów żywych zaproponowanej przez Chaberka. W dziedzinie teologii filozoficznej odpowiadam na pytanie o pochodzenie formy substancjalnej pierwszego przedstawiciela nowopowstałego gatunku, w odniesieniu do zagadnień dyspozycji materii i przypadłości substancji. Wracając do kwestii metafizycznych aspektów ewolucjonizmu, proponuję charakterystykę transformacji międzygatunkowej jako procesu, na który składa się wiele zmian substancjalnych i przypadłościowych.
In response to Michał Chaberek’s polemic with my position regarding theistic evolutionism, I refer to some key aspects of the Aristotelian-Thomistic philosophy and theology in their encounter with the theory of evolution and point toward some inconsistences and flaws in the argumentation developed by my adversary. After defining crucial aspects of Aquinas’s understanding of creation, I emphasize that evolutionary changes belong to divine gubernatio, and not creatio. I also offer an analysis of the question concerning the need of a direct divine intervention in instantiation of a new species. Moving to metaphysics I comment on the Aristotelian-Thomistic substantialism, the analogical character of substantivity, and Chaberek’s alternative taxonomy of living organisms. Regarding philosophical theology, I answer the question concerning the source of the substantial form of the first representative of a new species, in reference to the categories of disposition of matter and accidental features of substances. Addressing once again metaphysical aspects of the evolutionary theory I suggest characterizing species transformation as a complex process, engaging many substantial and accidental changes.

Opis:
Aconitum lasiocarpum (Carpathian endemic) and A. variegatum (European endemic) occur sympatrically in the Polish Western Carpathians. Here their taxonomic hybrid A. ×pawlowskii occurs. The aim of this study was to determine the relationship between the taxonomic (Linnaean approach) and genetic structure (PCR-ISSR analysis) of the populations and individuals in two allopatric and four sympatric populations. We determined 309 individuals (OTUs) to species, subspecies and nothospecies using the Linnaean system of classification, and then genetically fingerprinted 39 randomly chosen OTUs. Comparison of the Nei and Li distances obtained from ISSR and morphological matrices using the Mantel test indicated a significant correlation (n = 39, r = 0.53, P = 0.001). Genetic analysis (NEWHYBRIDS) pointed to 7 OTUs as being later-generation hybrids (B1 introgessants) in the sympatric area. Five of them belong to A. variegatum, indicating cryptic introgression, and two belong to A. ×pawlowskii. Nonmetric multidimensional scaling (NDMS) showed gene flow between A. lasiocarpum and A. ×pawlowskii. Allopatric, morphologically pure A. lasiocarpum and A. variegatum populations differed significantly in their ISSR profiles (Fischer's R×C test, P < 0.0001). Expected heterozygosity (Hj) was significantly (p=0.05) lower in allopatric (0.1261–0.1268) than in sympatric populations (0.1348–0.1509), indicating a genetic melting pot in sympatry. The results support the existence of a natural interspecific hybrid swarm zone in the sympatric area of occurrence of Aconitum, and the taxonomic circumscription of the nothospecies within the Linnaean taxonomic system.

Opis:
The co-occurrence of hybrids and parental species in similar ecological niches poses a question on the role of traits additivity and overdispersion (emergence of new traits) in microevolutionary processes. We analysed genetic polymorphism of Bromus benekenii, B. ramosus and the spontaneous hybrid B. benekenii × B. ramosus in sympatric and allopatric parts of the species distribution in Europe, based on non-coding regions of the taxon genomes (ISSR genetic fingerprinting). We tested 68 individuals in 7 populations, including a hybrid population in N France. Altogether 233 polymorphic ISSR bands (loci) were obtained. We found that the parent species were genetically distinct and the hybrids had an additive pattern of ISSR bands found in the putative parental species (NMDS, STRUCTURE); however, there was evidence of introgression towards B. ramosus (NEWHYBRIDS, UPGMA classifications, Nei's D genetic distance). Bromus benekenii had 72, B. ramosus 21 and the hybrids 9 private bands (genetic overdispersion), probably resulting from the rearranged genomes. Based on its low genetic divergence index DW, the hybrid population seems to be at a young age. We argue that in the face of anthropogenic landscape transformations favouring secondary contacts, the hybrids may competitively replace the parental species in sympatric areas.

Opis:
In the paper the long term dynamics (about 40 years) of selected, the most important, natural forest stands of the Białowieża Forest were presented. The studies were carried out on 120 permanent study plots, located both in nature reserves and in the Białowieża National Park. The DBH of all the trees were measured and the number of all the individuals trees and shrubs species with the height under 1,3 m was counted. The analysis of tree species composition and their density changes was carried out, as well as their natural regeneration was analyzed. The strong expansion of hornbeam were observed (fig. 1a, b; tab.). Actually this species was predominant in forest stands, in natural regeneration and was expansive to the more oligotrophic and mezotrophic forest stands, causing their unification towards hornbeam forest. Norway spruce generally declined in abundance and became limited to oligotrophic forest communities. Significantly reduction this species were observed, especially on the mixed coniferous forest at mixed deciduous forest stands. Scots pine, oak and birch declined their share in forest stands, as well as their natural regeneration have been limited too (tab.). In the short time of the last 15 years, the strong reduction of ash share in forest stands has been observed, and the more rapid changes in all the forest stands composition as well.

Opis:
The influence of different factors on amylolytic activity Bacillus cereus (2 strains) and Bacillus mycoides (2 strains), isolated from soil samples and water of Turawa Lake has been studied. Effect of physiological (pH of reaction mixture in the range of 4.0–8.0, temperature of reaction from 30 to 60 oC) and nutritional parameters (the carbon sources and they concentration in medium) were examined spectophotometricaly for their effect on amylase production. The results obtained showed, that in view of all studied factors the least favorable value of pH was 5.0, while in most cases the most favourable for the process of amylase production were following values 7.0 and 8.0. Moreover, it has been stated that the lowest amount of amylase was noted at 30 oC, and the highest at 60 oC. In case of amylolytic activity, in view of all temperatures the most effective strain was B. mycoides A134 whereas the least B. mycoides G3. The best results of amylase production have been achieved for all remaining strains in two cases – on maltose and glucose medium at all tested temperatures. Additionally, soil occurring strains preferred lower concentration of potato starch (ie 1 %) when compared with water strains which favoured higher concentration (5 %).
Celem badań była ocena wpływu różnych czynników na aktywność amylolityczną Bacillus cereus (2 szczepy) i Bacillus mycoides (2 szczepy) wyizolowanych z gleby i Jeziora Turawskiego. Metodą spektrofotometryczną badano wpływ pH mieszaniny reakcyjnej w zakresie od 5.0 do 8.0 i temperatury w zakresie od 30 oC do 60 oC oraz źródła węgla i jego koncentracji w podłożu na poziom produkowanych amylaz. Stwierdzono, iż najgorszą wartością pH do syntezy amylaz było 5.0, natomiast najlepszą, w większości przypadków pH 7.0. Uwzględniając zakres badanych temperatur, najwyższą aktywność uzyskano w temp. 60 oC, natomiast najniższą w temp. 30 oC dla wszystkich testowanych szczepów. Najbardziej aktywnym szczepem był B. mycoides A 134, natomiast najmniej B. mycoides G3.

Opis:
The main aim of the study was to determine changes in the species composition and structure of natural tree stands in the Białowieża Forest (BF), which occurred in the years 1975-2012, as well as to evaluate their trends, directions and rate. The study was carried out on 121 permanent research plots (50×50m), which represented the most important forest phytocenoses in BF, i.e. fresh pine-whortleberry forest Vaccinio vitis-idaeae-Pinetum Sokoł. 1980, fresh mixed spruce-reed grass forest Calamagrostio-Piceetum Soko³. 1968, oligotrophic form of hornbeam - bastard balm forest Melitti-Carpinetum Soko³. 1976, different forms of linden- hornbeam forest: Tilio-Carpinetum Tracz. 1962, alder-ash forest Fraxino-Alnetum W. Mat. 1952 and sub-boreal spruce forest on bog moss Sphagno girgenshonii- Piceetum Polak. 1962. On the plots selected, there was measured the diameter at breast height (DBH) of all trees, as well as every tree and shrub up to 1.3 m high was counted and described with reference to species. The measurements and observations were regularly repeated every 10-15 years. The results showed that over the last period of nearly 40 years, there has increased a share of common hornbeam Carpinus betulus L. in the structure of forest stands in numerous BF associations. This tree species has expanded into different forest habitats including poor, medium fertile and wetland sites. The results obtained indicate a trend towards formation of linden-hornbeam forests in BF phytocenoses. The most evident changes were recorded in hornbeam - bastard balm forest. In natural conditions of the majority of forest associations analyzed, there prevailed hornbeam trees in forest regeneration, except for the stands in fresh mixed pine forest and spruce forest on bog moss. In the latter two cases, hornbeam showed signs of its presence in the last observation period. Norway spruce (Picea abies L.) retreated into oligotrophic forest associations. In the recent decades, spruce populations have been dramatically reduced in the stands in mixed coniferous and different kinds of broadleaved forests. There have also decreased a share of light-demanding tree species, such as Scots pine (Pinus silvestris L.), pedunculate oak (Quercus robur L.) and silver birch (Betula pendula L.) in BF tree stands, including their regeneration-layer. Especially, Scots pine regeneration has not been successful. In the short period of time (about 15 years) there has been observed rapid and outsized reduction of ash Fraxinus excelsior L. populations in natural conditions of alder-ash forests. All through the last 10-15 years, there has been also observed increased rate of change in stand species composition. The trend and rate of change in stand species composition point out to a possibility of human intervention towards stimulation of natural regeneration so as to preserve valuable populations of threatened tree species in the Białowieża Forest.

Niniejszy artykuł zawiera główne wyniki badań i danych z obserwacji ekologicznych nad jakościowym zróżnicowaniem szaty roślinnej (flora i roślinność) na terenie 32 cmentarzy i ich bliskich stref otulinowych na Podbeskidziu Zachodniokarpackim (transekt wynosi około 120 km – od Cieszyna do Brzączowic koło Dobczyc i Zalewu Dobczyckiego; ryc. 1). Dokonano charakterystyki zróżnicowania gatunkowego flory naczyniowej Tracheophyta na wybranych 32 powierzchniach badawczych/cmentarzach i ich otulinach (o promieniu ok. 100 m). Określono także specyfikę składu gatunkowego flory naczyniowej poszczególnych, wybranych cmentarzy (od 324 do 506 gatunków i ich niższych taksonów), jak i w skali ogółu gatunków tej flory, stwierdzonych na tych obiektach (łącznie – 1250 gat. wraz z niższymi taksonami). Wykonano w terenie liczne spisy florystyczne oraz opracowano bardzo obszerny, naukowy zbiór alegatów zielnikowych, który złożono w Zielniku Naukowym Instytutu Botaniki PAN w Krakowie. Badano również udział we florze spontanicznie rozprzestrzeniających się składników synantropijnych, t.j. rodzimych apofitów i obcych antropofitów, a wśród nich dawnych przybyszy – archeoofitów przybyłych do Polski przed 1500 rokiem n.e.) oraz kenofitów, które przywędrowały do Polski po dacie odkrycia Nowego Świata/Ameryki (1492 r.) przez Krzysztofa Kolumba. Scharakteryzowano liczną grupę pielęgnowanych roślin ozdobnych obcego pochodzenia (jednoroczne, dwuletnie i byliny) wraz z aklimatyzowanymi przedstawicielami dendroflory (drzewa i krzewy). Zwrócono uwagę, że w składzie florystycznym wszystkich badanych cmentarzy znaczący udział (około 60%) ma również grupa alopatycznych roślin leczniczych, a wiele stosowanych jest w homeopatii. Zbadano zróżnicowanie synekologiczne / fitosocjologiczne budowanych przez te gatunki ugrupowań (zespoły sensu Braun–Blaquet 1964, Matuszkiewicz 2001 oraz inne oprac.). Natomiast ogólnoprzyrodnicze aspekty badawcze dotyczyły przede wszystkim pomnikowych drzew oraz spontanicznego, dzikiego występowania in situ roślin objętych ochroną prawną w Polsce, a także chronionych gatunków pielęgnowanych na cmentarzach ex situ (łącznie – ponad 30 gat. chronionych).
The paper presents mainly the results of studies and data from ecological analyses of the qualitative diversity of vegetation (plant communities and flora) of 32 cemeteries and their vicinity within the area of Podbeskidzie Zachodniokarpackie (approximately 120 km – from Cieszyn to Brzączowice in the Dobczyce Municipality, on Dobczyckie Lake; fig. 1). A profile of species diversity of vascular flora Tracheophyta within 32 selected study areas / cemeteries and their vicinity (within the radius of 100 metres). The characteristics of the species composition of the vascular flora of the selected cemeteries have been specified (324 to 506 species and lower taxa). Numerous vegetation lists have been compiled and an extensive scientific collection of herbarium specimens has been prepared, submitted to the National Herbarium of the Institute of Botany, PAN in Krakow. The study also concerned the participation in plant communities of the spontaneously spreading synanthropic components, namely native apophytes and foreign anthropophytes, also the plants that spread in the past, archeophytes (which appeared in Poland before 1500 AD) as well as kenophytes (which spread in Poland after the discovery of the New World/America by Christopher Columbus in 1492). A numerous group of cultivated ornamental plants of foreign origin has been described (annual, biennial and perennial), as well as the acclimatised dendroflora representatives (trees and shrubs). It has been observed that in the plant communities of all the analysed cemeteries, an important part (60%) is composed of allopathic medicinal plants, many of which are used in homeopathy. Synecological/ phytosociological diversity of such plant communities has also been studied (Braun–Blaquet 1964, Matuszkiewicz 2001 and other studies). Other general aspects of the study concerned mainly monumental trees and spontaneous, wild distribution in situ of plants protected in Poland, as well as protected plants cultivated at cemeteries ex situ (over 30 species of protected plants).

Opis:
New nuclear microsatellite markers (SSRs) were developed for Aesculus hippocastanum, a relict tree species from the Balkan Peninsula. The development of microsatellites was done using the Illumina MiSeq PE300 platform. Out of a set of 500 SSRs designed, a subset of 13 loci was tested using 290 individuals from seven natural populations. Twelve species-specific loci were polymorphic. The number of alleles per locus ranged from 2 to 17 and expected heterozygosity from 0.089 to 0.800 with a mean value of 0.484. The population of Kalampaka had the lowest value of allelic richness (2.63) and gene diversity in comparison to the remaining populations. STRUCTURE analysis confirmed isolation of population Mariolata from the southern edge of the species range and genetic similarity among populations from the Pindos Mts. Additionally, the utility of new SSRs in 29 individuals from nine other Aesculus taxa was tested. Eleven markers gave polymorphic products for all tested species. For 24 individuals, a high-quality product was obtained for each marker. Results confirmed the utility of specific markers for future population genetics studies.

Opis:
Quercus alnifolia is an endemic species in Cyprus, and it is rated as Vulnerable (VU) in the Red List of Oaks. Although Q. alnifolia has a great ecological importance, there are only few studies about this species. In this work we have studied the natural variability of this species by analyzing acorn dimensions, acorn mass, length of embryo, moisture content of acorns and seed germinability among the seven acorn provenances, collected in Cyprus. We also determined the seeds responses to drying. Germination trials were also carried out, and differences in seed germination among populations were examined. Rate of water loss and its effect on seed germination was also estimated by application of specific desiccation treatments. The results showed that acorn characteristics significantly differed between the populations, following a general trend to reduce their dimensions and mass with the altitude increase. Seed germination was high for all studied populations, and germination behaviour was similar for all populations. Desiccation of acorns below 35% resulted in a great reduction of seed germination capacity.

Opis:
We studied the relationship between tree-species diversity and the above-ground biomass on an example of two natural Polish forest with different altitiudinal range, plant species pool, vegetation and climatic conditions. The study sought to determine whether: (1) above-ground biomass in natural forests correlates with tree-species diversity irrespective of the kind of forest (montane or lowland), and (2) the relationship in question is negative, (3) the above-ground biomass is greater in montane forests than in lowland ones. Natural forests present in 1º Polish Gorce Mountains (montane forest) alongside comparable data for the 2º world-renowned lowland forest that is present in the Białowieża National Park. Data were collected within 558 sample plots (á 200-square-metre). The diameter at breast height of all trees with girths of or exceeding 12 cm was measured. To compute above-ground biomass we calculated dry masses for each tree on the basis of values for dbh and height, next we summed these values for all species present within each plot. The number of tree species on a plot ranged from only one (mainly in spruce stands) to six (in mixed deciduous lowland forest stands). The above-ground accumulated biomass ranged from 6 to 1155 (average 251±13) t ha–1 within the lowland forest, and from 2 to 849 (average 242±8) t ha–1 within the montane forest. We concluded that there was a humped-back shaped relationship between tree-species diversity and above-ground biomass in both lowland and montane natural forests.

Natural range of the Yellow Azalea Rhododendron luteum Sweet (Azalea pontica L.) includes the Caucasus, Asia Minor, Volhynia and SE rim of the Alps (Slovenia). There is also a natural locality of this species in Poland, in Wola Zarczycka near Leżajsk. The plant was discovered in 1795 in Volhynian Polesia by an eminent gardener Dionizy Mikler, and its popularity grew thanks to the Botanic Garden affiliated by the Krzemieniec College. Already at the first half of the 19th century Yellow Rhododendron, originating from Volhynian Polesia, was in cultivation in most of European Botanic Gardens. Nowadays this species can be easily found even in small private gardens. It has also been planted in forests. In Volhynian Polesia it grows abundantly in continental mesotrophic oak-pine mixed forests (Querco roboris-Pinetum), sometimes covering 100% of the shrub layer. Its is equally common in continental swamp pine forests (Vaccinio uliginosi-Pinetum). The soils where the species grow are always moist and very acidic (pH below 4). In Volhynia plant communities with R. luteum cover over 1.5 billion ha. In Ukraine the plant is not protected by law.

Opis:
The paper presents results of a survey of natural monuments in the Śrem county, Poland. The survey inventoried eight avenues, 30 tree clusters, six erratics, two localities of a protected plant species, and 85 trees-natural monuments. Among all trees the most numerous group comprised small-leaved limes (447 trees – 36.6%), horse chestnuts (372 Aesculus hippocastanum – 30.4%) as well as Acer platanoides and Quercus robur (with 99 trees each – 8.1%). Among single trees classified as natural monuments the greatest numbers belong to Quercus robur (34 trees – 40.0%) as well as Aesculus hippocastanum and Tilia cordata (with 8 trees each – 9.4%). In the area of the survey there are 30 clusters of trees registered as natural monument. These clusters comprise 99 trees belonging to eight species. Among them English oaks vastly predominate – 65 trees (65.7%). Eight avenues are composed of 1038 trees belonging to seven species. The avenue with the highest number of trees is situated in Przylepki (the Brodnica comune), extending for 1.5 km and composed of 265 Tilia cordata specimens. Former manor and palace parks in the Śrem county account for 33% trees-natural monuments and 63% tree clusters. Considerable differences were recorded in the numbers of natural monuments registered in individual decades – in the 1950’s nine natural monuments were established (6.9% total number of natural monuments), in the 1960’s – one (0.8%), the 1970’s – one (0.8%), the 1980’s – 41 (31.3%), the 1990’s – 73 (55.7%), while in the first decade of the 21st century six natural monuments were registered (4.6%).

Opis:
Solidago species are one of the most widespread invasive species in Europe. In Central Europe, vegetation dominated by alien goldenrods can occupy vast areas. Their presence causes a decrease in the biodiversity level of numerous groups of organisms (plants, birds and insects). Alien Solidago also disturb biogeochemical cycles, as well as the primary productivity in infested ecosystems. In Central Europe, four alien Solidago species are considered as naturalized plants: late goldenrod (Solidago altissima L.), Canadian goldenrod (S. canadensis L.), tall goldenrod (S. gigantea Aiton), and grass-leaved goldenrod (S. graminifolia (L.) Elliot. = Euthamia graminifolia (L.) Nutt.). To analyse the dynamics of the growth and flowering of Solidago species, an experiment was conducted in which the goldenrods were planted in pots. We examined the life history traits, which are treated as being strongly connected with the invasive abilities of these species. The height, number of ramets and percentage of flowered plants were noted at ten-day intervals from May to November over a period of four years. Two native species, often co-occurring with alien goldenrods, were analysed for comparison: European goldenrod (Solidago virgaurea L.) and common tansy (Tanacetum vulgare L.). The analysed species reached their maximal height during the second and third years of the experiment. The highest ramets were noted in the case of Solidago altissima, S. canadensis and S. gigantea. A group of lower plants consisted of Solidago graminifolia, together with the native species S. virgaurea and T. vulgare. The number of ramets formed by S. graminifolia was more than two times larger than in the case of other species. All of the analysed species flowered during the time of observation but, grass-leaved goldenrod, was the only one among the alien species which flowered in all pots and 100% of individuals produced mature seeds. Its phenology (early flowering and seed ripening) was more similar to native species’ than to other alien Solidago. Our results suggest Solidago graminifolia has strong competitive abilities; however, its range is very limited. The reasons for the slow spread of this species in Europe – other than competitive limitations – should be considered.

Opis:
The paper takes up Paul W. Taylor’s theses (beliefs) concerning the relations between human beings and the environment. First thesis sets forth that humans are members of the Earth community of life; second, humans are interrelated with other species; third, all organisms are teleological centers of life tending to fulfill their inner good; fourth, humans are equal with other living creatures. These theses are analyzed in-depth and critically assessed. Most controversial is the last belief. It implies that all living creatures have the same value and should be treated equally. The paper shows that these assertions are not viable. More realistic is the idea that natural living creatures differ as far as their values are concerned. Hence, in the paper is undertaken an attempt to figure out a method of disclosing these axiological differences, starting from a personalist model describing mutual relations between anthropology and ethics.

Opis:
English yew is rare and endangered dioecious species. Research on regeneration processes of endangered taxa is important to understand the mechanisms allowing a species to survive under several ecological scenarios, to predict future distribution shifts, to achieve best management practices and conservation policies. Our investigation was focusing on one of the oldest yew population in Europe, in Foresta Umbra in Italy. The main aim of this study was to understand spatial regeneration processes and dynamics related with parent trees’ sex distribution. Geostatistical analysis showed that seedlings occur in patches avoiding direct competition with adult yews. Negative relationship between regeneration and yew density and basal area was found. A general model for the reproductive ecology is proposed: females are less competitive and more environmentally demanding than males, because of their reproductive effort. Indeed, male and female fitness responds differently across environmental gradients, thus favouring spatial segregation of seedlings. Understanding the yew’s adaptive effectiveness is essential to ensure the conservation of existing populations, and encourage the species’ resilience into areas where yew is endangered.

Opis:
In the last decades, we observed significant changes in the tree species composition in all layers of close−to−natural stands. Since the 1970s, the Forest Research Institute has collected and stored dataset from stand measurements, phytosociological and other research that are the basis for the long−term monitoring of vegetation. The aim of the research was to determine the directions of changes in the species composition and structure of tree stands, and to analyze the changes in the species composition of natural regeneration growing without human interference in various forest communities in the period of about 40 years. From 2014 to 2017, 40 permanent plots of 0.25 ha were re−measured in the nature reserves of the Knyszyn and Augustów Forests (NE Poland). The diameter of all trees was measured and the trees of the natural regeneration and bushes up to 1.3 m high were counted. The stand similarity index (S) between successive measurements was calculated. The analysis of differences in the composition of tree stands in subsequent measurements was carried out using Student t and Kruskal−Wallis tests. In the species composition of fresh coniferous forest stands and fresh mixed coniferous forest, there were significant changes in the number and share of Scots pine and Norway spruce. In the Knyszyn Forest a significant decrease in the share of spruce was observed. However, an increase in the share of deciduous species was remarkable. An inhibition of the natural pine renewal process and increase in density of spruce regeneration was observed. It is necessary to emphasize the significant expansion of hornbeam in a fresh mixed deciduous forest in the Knyszyn Forest and expansion of hazel in the Augustów Forest. Mean basal area in the forest stands has increased. The similarity index between the beginning and the end of the research reached the value of 0.73−0.94. The species composition and density of natural regenerations created without human intervention are not satisfactory from the point of view of forest sustainability. The most important factor affecting the direction and rate of changes in the species composition of tree stands is the expansion of hornbeam and/or hazel. These species cause changes in the ecological conditions of the lowest forest layers, leading to the unification of the species composition of forest communities.

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:
Praca prezentuje wpływ opanowywania (ekspansji) gatunków roślin obcego pochodzenia na krajobraz Lublina. Gatunki te mogą być cenne w miastach czy na terenach zdegradowanych, gdzie potrafią przetrwać w warunkach niesprzyjających gatunkom rodzimym. Ich nadmierne rozprzestrzenianie, negatywny wpływ na rodzime gatunki staje się niebezpieczne. W Lublinie sześć gatunków synantropijnych uznano za mające znaczenie w unifikacji krajobrazów roślinnych miasta. Zasięg występowania tych gatunków roślin obejmuje niemal wszystkie dzielnice poza Śródmieściem i Starym Miastem czyli ścisłym centrum miasta. Istotny wpływ odnotowano szczególnie w przypadku dwóch gatunków roślin z rodzaju nawłoć (Solidago gigantea i Solidago canadensis), które ekspansywnie opanowują tereny wcześniej porośnięte roślinnością naturalną i synantropijną. Powoduje to zmniejszenie różnorodności gatunkowej roślin, wypieranie roślinności cennej (murawowej) oraz ujednolicanie krajobrazów roślinnych miasta. Dlatego istnieje potrzeba rozpoznania tego zjawiska, podejmowania prób kontroli rozprzestrzeniania się gatunków obcych w krajobrazie oraz ochrona unikatowych zbiorowisk roślinnych i pełniejsze wykorzystanie elementów roślinności rodzimej na terenach zurbanizowanych.
This paper presents the influence of infestation (expansion) of alien plant species on the landscape of Lublin. Such species can be valuable in cities or in degraded terrains, where they can survive in conditions unfavourable to native species. Their excessive proliferation and negative impact on native species is becoming dangerous. In Lublin six synanthropic species were deemed pivotal in unifying the natural landscapes of the city. These plant species cover nearly all city districts, apart from “Śródmieście” and “Stare Miasto”, which are in direct city centre. A significant influence was noted especially in the case of two plant species from the goldenrod genus (Solidago gigantea and Solidago canadensis), which spread extensively over areas previously covered with natural and synanthropic vegetation. This causes a reduction in plant species diversity, displacement of valuable (grassland) plant life, and also homogenisation of natural landscapes in the city. Therefore, there is a need to identify this phenomenon, to attempt to control the spread of alien species within the landscape, and to protect unique plant communities, as well as to fully utilize elements of native vegetation in urban areas.
