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:
Plant diaspore dispersal is a fundamental process affecting the development of forest vegetation and its natural regeneration, especially with regard to typical woodland species, which spread slowly and form short-term soil seed banks. Most of these species have poor seed dispersal mechanisms, which is the major cause of their very slow expansion. The following questions were asked: (i) is there a relationship between the age of a woodland and the presence of forest vascular plant species representing different seed dispersal types; (ii) how do the proportions change between species representing different seed dispersal types in relation to the age of woodland; (iii) what factors determine the presence of species representing a given seed dispersal type; (iv) which factors affect the presence and which ones influence the abundance of selected woodland species? A multiple regression models were developed based on data obtained from 144 woodland patches designated for the study. A probit regression analysis was performed for selected species exhibiting various seed dispersal models. Woodland plants of all seed dispersal types show a significant relationship with the age of woodland, starting from the strongest linkage: anemochores, myrmecochores, endozoochores, epizoochores, barochores, autochores. As the woodland ages, the proportion of forest myrmecochores and anemochores grows, whilst the proportion of autochores, epizoochores and endozoochores shrinks. Results obtained indicate that the direct proximity of ancient woodland has a major effect on the occurrence of more poorly dispersing plants in recent woodlands, such as myrmecochores and heavy anemochores.

Opis:
Riparian zones in two rivers in southern Poland were studied in terms of species composition and soil parameters in patches dominated by three knotweed taxa (Fallopia japonica, F. sachalinensis and the hybrid F. ×bohemica). The main purpose was to detect any differences in species diversity, environmental conditions and in the impact of the three Fallopia spp. on resident species. Fieldwork was conducted in spring and summer in 30 invaded plots (in total 90 subplots). It was demonstrated that vegetation dominated by particular knotweed taxa differed in response to soil pH and ammonium, nitrate, and magnesium content. Fallopia spp. (living plants and necromass) had a stronger negative impact on the cover and species diversity of the resident species in summer in comparison with spring. Vegetation patches differed significantly in species composition in relation to the knotweed taxa present. These differences may be the consequence of the differentiated biotopic requirements of Fallopia taxa and the coexisting plants, or to the different impact of the knotweed taxa on the resident species.

Opis:
A numerical analysis of the phytosociological relevés from ancient and recent woodland on a mesic forest site in central Poland was carried out. Three groups of forest stands were recognised: planted with Pinus, recent and ancient oak-hornbeam Tilio-Carpinetum. The species of ancient woodland occurred mainly in ancient oak-hornbeam forest stands, however some ferns: Dryopteris carthusiana, D. dilatata and D. filix-mas, and an orchid species Epipactis helleborine, are to be found mainly or exclusively in recent forests. The occurrence of ancient forest species in recent woods may be putatively explained by long-distance wind dispersal or by the thriving in situ in unrecognised small wood patches. Twelve ancient woodland indicators (i.e. 36% of a total number found in the region under study) occur exclusively in ancient woodland. It underlines the role of passive species protection in the maintenance of the regional species diversity.

Opis:
We provide information about two species, Pilosella bauhinii and P. cymosa subsp. vaillantii (Asteraceae), from new localities in north-central Poland (ATPOL DC18). All individuals of both species grew on a railway embankment in Górzno-Lidzbark Landscape Park. The ecological preferences for P. cymosa and P. bauhinii estimated according to average Ellenberg values nearly coincided with the original description of Ellenberg. We also sequenced the barcode marker, plastid trnH-psbA intergenic spacer, for two individuals of P. bauhinii, three specimens of P. cymosa subsp. vaillantii, and additionally two individuals of P. officinarum L. and one H. murorum L. growing in close proximity. A pairwise comparison of trnH-psbA sequences showed that each species has a unique haplotype. Taking into account their morphological coherence, it is possible that both P. bauhinii and P. cymosa have not hybridized yet, at least locally, with the more abundant species (e.g., P. officinarum). A search for reference sequences did not provide additional information because of the low quality of the reference database for this group in GenBank. Only 14 sequences of trnH-psbA were available with some apparently being misidentified or of low quality. None were identical to sequences of P. cymosa subsp. vaillantii and P. bauhinii found in this study.

Opis:
Attempts to study biodiversity hotspots on a regional scale should combine compositional and functionalist criteria. The detection of hotspots in this study uses one ecologically similar group of high conservation value species as hotspot indicators, as well as focal habitat indicators, to detect the distribution of suitable environmental conditions. The method is assessed with reference to thermophilous forests in Poland – key habitats for many rare and relict species. Twenty-six high conservation priority species were used as hotspot indicators, and ten plant taxa characteristic of the Quercetalia pubescenti-petraeae phytosociological order were used as focal habitat indicators. Species distribution data was based on a 10 × 10 km grid. The number of species per grid square was interpolated by the ordinary kriging geostatistical method. Our analysis largely determined the distribution of areas with concentration of thermophilous forest flora, but also regional disjunctions and geographical barriers. Indicator species richness can be interpreted as a reflection of the actual state of habitat conditions. It can also be used to determine the location of potential species refugia and possible past and future migration routes.

Opis:
During the survey of the Mały Borek nature reserve (Augustów Forest, NE Poland) 236 species of vascular plants were recorded, including 10 plant species red-listed in Poland and 19 species protected under the Polish law. The most valuable species were sedges typical of the boreal coniferous forests: Carex vaginata, C. globularis and C. loliacea. The presence of neophytes was very limited (1,3% of the flora) in the area studied. The principal aim of the establishment of the reserve was the conservation of old-growth coniferous forests with long ecological continuity. Since the reserve studied consists mainly of old-growth coniferous forests, the number of species regarded as ancient forest indicators is lower (54 species) than in the well-preserved reserves with deciduous stands in north-east Poland, but still rather high. The most valuable, threatened species are bound to wetland forests that are presently disturbed due to drainage. Restoration of the former hydrological conditions is essential for the preservation of the vascular plants in the reserve.

Opis:
The genus Tradescantia comprises about 70 species. In Poland Tradescantia x andersoniana is basically grown as an ornamental plant that is recommended for borders and to be planted around garden ponds. The present study investigated flowering as well as the micromorphological and anatomical features of some floral elements of Tradescantia x andersoniana W. Ludw. Rohweder ‘Karin’. The macro- and micromorphology of the flowers was examined using stereoscopic, light, and scanning electron microscopy (SEM). Spiderwort produces flowers with a diameter of 4.6 – 5 cm, which open early in the morning and close at noon. Non-glandular and glandular hairs grow on the abaxial surface of the calyx and on the apical part of the ovary. The glandular hairs develop a several-celled stalk and a unicellular spherical or elongated head. The staminal filaments produce chain-shaped trichomes. Striate cuticular ornamentation is found on their surface and on the epidermis covering the perianth. The striae on the cells of the stamen hairs run to the two poles of the cell. The pistil develops a wet stigma with unfused unicellular papillae. The cuticle on their surface is smooth, whereas on the style near the stigma it forms dense folds.
Rodzaj Tradescantia obejmuje około 70 gatunków. W Polsce Tradescantia x andersoniana uprawiana jest w gruncie jako roślina ozdobna, zalecana na rabaty i wokół zbiorników wodnych. Przeprowadzono badania obejmujące kwitnienie i cechy mikromorfologiczne oraz anatomiczne wybranych elementów kwiatowych Tradescantia x andersoniana W. Ludw. Rohweder ‘Karin’. Makro- i mikromorfologię kwiatów analizowano przy użyciu mikroskopii stereoskopowej, świetlnej i skaningowej elektronowej (SEM). Trzykrotka wykształca kwiaty o średnicy 4,6-5 cm, które rozkwitają wczesnym rankiem i zamykają się w południe. Na powierzchni odosiowej epidermy kielicha i wierzchołkowej części zalążni wyrastają włoski ochronne oraz wydzielnicze różniące się strukturalnie. Ich największą liczbę stwierdzono na odosiowej epidermie kielicha. Włoski gruczołowe wykształcają kilkukomórkową nóżkę i jednokomórkową, kulistą lub wydłużoną główkę. Nitki pręcika tworzą trichomy o łańcuszkowatym kształcie. Na ich powierzchni i epidermie okrywającej okwiat występuje prążkowana ornamentacja kutykularna. Prążki na komórkach włosków pręcika zbiegają do dwóch biegunów komórki. Górny słupek wykształca mokre znamię z niezrośniętymi, jednokomórkowymi papillami. Na ich powierzchni kutykula jest gładka, natomiast na szyjce słupka w pobliżu znamienia tworzy gęste pofałdowania.
