    Polystichum setiferum
    Opis:
    During field studies in 2019 in the Beskid Śląski mountain range in southern Poland, one individual morphologically resembling Polystichum setiferum was found. Nuclear DNA content analysis confirmed the species identity. The new stand of P. setiferum corresponds to historical literature reports and herbarium specimens from the Czech Republic and Poland, and extends the northeastern limit of the distribution of this species. As the historical stands in both countries have not been confirmed, the newly discovered stand is at present strongly isolated, as the nearest extant locations of P. setiferum in Austria, southern Hungary, and western Romania are nearly 500 km away. Therefore, this unique stand deserves special attention and protection.

    Opis:
    Heterogeneous and disturbed habitats within railway areas create an ideal environment for establishment of invasive plant species. In this study, we compared the invasive species composition and abundance within railway areas of two cities, Lublin, SE Poland and Lviv, W Ukraine. In total, 70 invasive species were recorded. The invasive species list was similar for the two cities, with the most invasive species occurring at both (81.4%), 8.5% occurring only in Lublin and 10% only in Lviv. The proportion of invasive species in the total flora was almost 1.5-fold higher at Lviv compared to Lublin. Invasive species have originated mainly from continental America (45.7%), followed by Asia and Eurasia. The participation of invasive plants derived from Asia and Eurasia at Lviv is higher than at Lublin. The invasive flora includes a wide range of taxonomic groups, with a predominance of Asteraceae and Poaceae. The ecological attributes of invasive species on railway areas are: mainly annual therophytes, mostly wind- and insect pollination modes, a predominance of generative reproduction, anthropochorous and anemochorous dispersal and short-term persistent, long-term persistent or transient seed banks.
    Zróżnicowane i zaburzone siedliska w obrębie terenów kolejowych tworzą środowisko do zadomowienia obcych gatunków roślin. W pracy porównano skład oraz bogactwo gatunkowe gatunków inwazyjnych notowanych w obrębie terenów kolejowych Lublina (południowo-wschodnia Polska) oraz Lwowa (zachodnia Ukraina). Zanotowano 70 gatunków inwazyjnych. Skład gatunkowy flory inwazyjnej był w obu miastach podobny; 81.4% gatunków inwazyjnych notowano w obu miastach, 8.5% tylko w Lublinie, a 10% tylko we Lwowie. Udział gatunków inwazyjnych we florze Lwowa był wyższy w porównaniu z florą Lublina. Gatunki inwazyjne pochodziły głównie z Ameryki (45.7% gatunków), Azji i Eurazji. Udział gatunków inwazyjnych przybyłych z Azji i Eurazji był wyższy we Lwowie niż w Lublinie. Gatunki należące do rodziny Asteraceae i Poaceae dominowały wśród gatunków inwazyjnych. Analiza cech ekologicznych gatunków inwazyjnych zasiedlających tereny kolejowe wykazała, że są to głównie rośliny jednoroczne, wiatro- lub owadopylne, rozmnażające się generatywnie, o nasionach rozsiewających się antropochorycznie lub anemochorycznie, tworzące krótkotrwały lub długotrwały bank nasion.

    Opis:
    In fall 2018 and 2019, we assessed colonization by fungi on Douglas fir trees [Pseudotsuga menziesii (Mirb.) Franco], white pine (Pinus strobus L.), and red cedar (Thuja plicata D. Don.) on selected experimental plots of the former Prussian Experimental Station, where nonnative tree species were introduced from North America over a century ago. The presence of sporocarps on trunks, root collars, and stumps as well as the litter layer in the soil within a radius of 0.5 m around the trunk of the tree was determined. Additionally, the volume of dead wood on the forest floor of the entire plot was assessed. We recorded numerous fungi on trees and stumps as well as in the litter and soil. For the 31 plots in 12 forest districts, we determined 745 sporocarps of 48 taxa, with 335/19 on the wood of P. menziesii trees and stumps, 377/15 on P. strobus, and 33/6 on T. plicata trees. The highest share of trees with various trunk damage levels was found for T. plicata (70.3%) and the lowest for P. menziesii (6.2%). Among the root parasitic fungi, Heterobasidion sp. and Armillaria sp. were found, especially on the collars and stumps of T. plicata and P. strobus; we did not find basidiomata of both pathogens on P. menziesii. The volume of dead wood within the P. menziesii plots averaged 7.1 m3/ha, whereas in T. plicata plots, it was 56.3 m3/ha. We identified 10 taxa that have not been reported in association with P. strobus for Poland (Cylindrobasidium laeve, Dacrymyces sp., Exidia pithya, E. saccharina, Gymnopilus pnetrans, Leptoporus mollis, Mycena sanguinolenta, Tapinella panuoides, Trametes versicolor, and Xylaria hypoxylon) and three taxa (Exidia pithya, Leptoporus mollis, Serpula himantioides) associated with T. plicata.

    Opis:
    The aim of the study was to characterize and analyze the segetal flora of the Łuków Plain. The study was carried out from 2003 to 2006 in 182 towns and villages. Vascular flora of the arable fields in the area under study consists of 305 species belonging to 39 families and 168 genera. The analysed flora is characterised by the prevalence of native species (64.6%) over alien species (35.4%). Archaeophytes dominate among anthropophytes, whereas meadow species are the most frequent in the group of apophytes. Annuals and biennials show a slight prevalence over perennials. The analysis of the life-form categories shows the dominance of therophytes (52.8%) as well as a relatively high share of hemicryptophytes (34.4%) and geophytes (12.5%). In the analysed flora, rare and very rare species constitute a vast majority (61.7%), whereas the common and very common species reach 13.1%.
    Celem pracy była charakterystyka i analiza flory segetalnej Równiny Łukowskiej. Badania prowadzono w latach 2003-2006 na terenie 182 miejscowości. Flora naczyniowa pól uprawnych badanego terenu liczy 305 gatunków należących do 39 rodzin i 168 rodzajów. Na bogactwo gatunkowe ma wpływ zróżnicowanie siedlisk, rozdrobnienie gospodarstw i tradycyjny system gospodarowania. Analizowana flora cechuje się przewagą gatunków rodzimych (64,6%) nad taksonami obcego pochodzenia (35,4%). Wśród antropofitów dominują archeofity (27,2% flory) a z apofitów najczęściej notowano gatunki łąkowe (23,6% flory). Gatunki krótkotrwałe mają niewielką przewagę nad wieloletnimi. W obrębie form życiowych dominują terofity (52,8%), zwłaszcza wśród antropofitów (85,2% gatunków tej grupy), ale stosunkowo dużo jest hemikryptofitów (34,4%) i geofitów (12,5%). W analizowanej florze największy udział mają gatunki bardzo rzadkie i rzadkie (61,6% flory), natomiast pospolitych i bardzo pospolitych jest 13,1%. Cechą charakterystyczną jest liczne występowanie gatunków speirochorycznych związanych z ekstensywnym rolnictwem: Agrostemma githago, Bromus secalinus i Avena strigosa. Z gatunków subatlantyckich częstym taksonem jest Arnoseris minima, rzadkim Anthoxanthum aristatum, a Teesdalea nudicaulis występuje bardzo rzadko na badanym terenie.

    Opis:
    Montia linearis is a vascular plant originating from western North America. The expansion of this species has been observed for several decades. For the first time M. linearis was found in Europe in 1989. Further six populations were documented by 2004 within the continent: three in Poland, two in Denmark and one in Hungary. Apart from discovering a new population of M. linearis, we confirmed two out of the three previously known localities of the species in Poland. All the currently known populations of M. linearis occupied predominantly meadow habitats, especially intensively managed sites. Some individuals were also found in disturbed sites with bare soil. The studied species inhabited soils of various types with broad range of fertility as well as humidity. Montia linearis populations reached densities up to 87 individuals per 0.04 m2. The number of seeds produced by an individual was between 10 and 55 in 90% of the studied specimens, however much more fertile specimens were also observed. As the previously presented hypothesis of M. linearis dispersal with rail transport seemed not to be well supported, the connection between the M. linearis presence and cattle husbandry is considered. It is possible that the species can be transferred with living animals or manure. The species was able to survive for at least 26 years within once inhabited site. Further spread of M. linearis within Europe is highly probable. The aim of the study is to: (i) describe the current state of populations of M. linearis in Poland, (ii) provide information on habitat preferences and biology of the species, (iii) assess the invasiveness potential of M. linearis in Poland.

    Opis:
    The paper presents the results of several years investigations (2003-2007) on two invaders: the Himalayans Impatiens glandulifera and Asiatic Reynoutria japonica. The Sudety Mountains and their national parks are under strong pressure of both species, threatening the local vegetation. The four-year investigations have been carried out in field, glasshouse and in laboratory. Invasive species have their peculiar life histories which help them to occupy new areas. Those are above all the specific generative reproduction strategies (Impatiens) or vegetative reproduction strategies (Reynoutria). Both strategies secure the reproductive success and to capture more and more highly situated areas of the mountains. Very significant characteristics connected with the expansion of invaders is the excessively over and above the average production of seeds (Impatiens) and a huge annual increment aboveground biomass (Reynoutria). The investigated invasive species are probably not equipped with influence of allelopatic type as of greater importance is their competitive strength. The invaders can eliminate a part of the early spring flora belonging to the geophyte group and impoverish the regional biological diversity. Both the invasive plants enter also into some moist mountain forest communities.

    Opis:
    The morphology of pollen grains of 16 species from the Rosa L. genus were studied (i.e. R. agrestis, R. canina, R. dumalis, R. gallica, R. inodora, R. jundzillii, R. kostrakiewiczii, R. majalis, R. micrantha, R. mollis, R. pendulina, R. rubiginosa, R. sherardii, R. tomentosa, R. villosa, and R. zalana). The material came from 16 native localities of those species in Poland. The measurements are based on at least 30-50 randomly selected, fully developed pollen grains per specimen. In total, 500 pollen grains were examined. They were analysed for 13 quantitative features of pollen grains and exine sculpturing and the following qualitative traits: outline, shape, "operculum" structure. The diagnostic features of pollen grains of studied species were: length of polar and equatorial axes and length of ectocolpi. The above-mentioned pollen grain morphological features make isolation of one species possible: R. gallica. R. gallica is distinguished for its highest values of the length of polar and equatorial axes, and the length of ectocolpi. The obtained analytical results of operculum and exine sculpture features, considered as diagnostic, corroborated only slightly their priority significance for the isolation of the examined species and sections. The collected data failed to confirm fully the current taxonomical division of the Rosa genus into sections (only section Gallicanae from R. gallica is isolated) as well as consanguinity relationships between the examined species from the Caninae section. On the dendrogram, both species closely related with each other as well as those from other developmental lines were found in the same group. These equivocal results are by no means surprising because the Caninae section is the most polymorphic group in the Rosa genus, and contemporary Caninae are of the nature of a swarm of R. canina hybrids as a link combining all taxons of the section.
