Glyceria striata (Lam.) Hitchc. is a North American species that has been recorded in most, semi-natural habitats in Europe, e.g. in meadows, bog springs, margins of water bodies. It is circumscribed within two taxa of lower rank: G. striata subsp. striata and G. striata subsp. stricta. Only G. striata subsp. stricta has been reported from Europe. This paper gives a list of the European localities of the species (48) and describes two newly discovered localities in Poland (the Wyżyna Małopolska upland and the Western Carpathian Mts.). The distribution of G. striata in Europe is mapped and potential migration routes of the species are discussed.

Parasitic plants species of the genus Orobanche produce a very high number of small dust-like seeds. The seed shape of Orobanche sp. is ellipsoid to globose, ca. 0.3 × 0.4 mm. Orobanche picridis F.W. Schultz is a sub-Mediterranean-sub-Atlantic species. It has the NE range limit in Poland and Ukraine. The species is seriously endangered in Poland and neighbouring countries. O. picridis occurs only in southern Poland (34 localities). It prefers habitats on chalky rendzina, especially S-facing. It colonizes abandoned fallows and wastelands, field margins, initial xerothermic grasslands. They are mostly ecotone communities, in semi-ruderal xerothermic pioneer communities belonging to the Dauco-Picridetum (Artemisietea vulgaris class). The aim of this study was to determine potential and real seed productivity in Orobanche picridis and correlations between the characteristics of the shoots. Research hypothesis is to show that the studied traits of shoots show the highest correlation with the production of seeds. The paper presents investigations into potential and real seed productivity of Orobanche picridis for the first time. Investigations were conducted in 2010 at three most abundant localities of O. picridis in southern Poland in the Wyżyna Małopolska upland (S Poland) - Wesołówka (Przedgórze Iłżeckie foreland), Pińczów, and Pęczelice (Niecka Nidziańska basin). Research into the number of seeds produced per fruit and per shoot is discussed. Strict correlations between seed productivity and shoot features, i.e. shoot height, inflorescence length, number of fruits and corolla tube length were observed. The number of seeds in a single ovary in O. picridis varied and ranged from 457 to 3 246. The mean number of seeds per shoot is 55 172 based on the data collected at the three sites and ranges between 8 911 and 151 050. Seed productivity depends significantly on the size of a plant, that is on the shoot height, correlation coefficient r = 0.7, inflorescence length, r = 0.6, number of flowers and fruits per plant, r = 0.6, and on the flower size, r = 0.5.

In anthropogenically disturbed habitats, natural barriers still exist and have to be recognized, as they are important for conservation measures. Areas of phylogeographic breaks within a species are often stabilized in inhospitable regions which act as natural barriers. An area of contact between phylogeographic lineages of the common hamster (Cricetus cricetus) was found in the Małopolska Upland in Poland. A total of 142 common hamsters were captured between 2005 and 2009. All hamsters were genotyped at 17 microsatellite loci and partial sequences of the mitochondrial (mtDNA) control region were obtained. No mixed populations with mtDNA haplotypes of both lineages were found. The distance between marginal populations was about 20 km; no hamsters were found in the area between. A principal components analysis (PCA) was performed on microsatellite data and the greatest change in PC1 scores was found between marginal samples. To define the habitat components responsible for the phylogeographic break, we compared the habitat composition of sites occupied by hamsters with those from which hamsters were absent. We found that hamsters avoided forested areas and sandy soils. The area of the potential barrier was characterized by a high proportion of woodland and unfavorable soils in comparison with neighboring areas inhabited by hamsters. They cannot settle in this area due to their high winter mortality in shallow burrows and high predation in the fields adjacent to forests.

The aim of the present research work was to evaluate the influence of lithogenic conditions on the physico-chemical properties, quantity and quality of humus components in the black earths from the Małopolska Upland. Soil samples were collected from 5 soil profiles which represented proper black earth (profiles No. 1-4) and degraded black earth (profile No. 5). All the investigated soils were under sward. The examined black earths were characterised by different physico-chemical properties strongly related to the parent rock type. Their pH level and sorption capability were decreasing with a decrease in the clay content of the soil texture. Humus resources were the lowest in sandy black earths (average 212 t ha-1) and the highest in the black earh derived from clay (454 t ha1). In the humus composition of the examined black earths, humic acids dominated over fulvic acids. In the A horizons, the Ch:Cf ratio was close to 1, and lower in the upper parts of these horizons which is typical of turf soils. Humus horizons in some of the investigated black earths were classified as epipedon anthropoid according to phosphorus content soluble in 1% citric acid (109 P kg-1 soil).

This study present 9 species of colourless euglenoid flagellates found in a small peat bog in Budzyń, a village north-west of Cracow, which belongs to the Małopolska Upland (Southern Poland). This threatened peat bog is covered with rubble brought from neighbouring Cracow. Only ca 30% of its area is relatively little influenced by human activity. Many of the present species are rarely and infrequently reported from nature. Three species, including Rhabdomonas incurva Fresenius, Entosiphon obliąuum Klebs, E. ovatum Stokes, and one variety Menoidium pellucidum Perty var. gracile (Playfair) Popova have been recorded for the first time from Poland. Three species Astasia dangeardii Lemmermann var. dangeardii, Rhabdomonas costata (Korsikov) Pringsheim and Entosiphon sulcatum (Dujardin) Stein var. sulcatum Stein are new for the flora of Cracow-Częstochowa Upland. The remaining taxa: Menoidium pellucidum Perty var. pellucidum and M. tortuosum (Stokes) Senn var. tortuosum are very rarely recorded from Poland. For each species illustrations, taxonomic information and biogeographical data are given.

The human induced changes affect the transformation of different plant communities. In some cases this process can contribute to increase in local biodiversity, but it depends on type and manner of human activity involved. The main aim of this study is to answer the question how two anthropogenic factors (former and current) can modify the species composition in forest phytocoenoses. The study area is situated in the southern Poland (Małopolska Upland). The studies were carried out on two former (19th century) mining fields where planting Common Beech Fagus sylvatica (field A) and Scots Pine Pinus sylvestris (field B) have been done since the first half of the 20th century. On gob piles (sites transformed by former iron-ore mining), single-species beech (field A) or pine (field B) tree stands are undergoing secondary succession, and transform into multi-species, fertile deciduous forests. This secondary communities corresponding to the types of new, fertile soils (formed by clayey-loamy material of gob piles), generated as a result of mining activities. Whereas, on non-transformed areas forest communities with floristic structures and composition linked to poor and acidophilous phytocoenoses developed. These communities are also compatible with their respective, primary habitats (acid, poor, and sandy soils). Nonetheless, the secondary succession of forest communities on gob piles can be disturbed. In the herb layer of fertile habitats of post-mining sites where Pinus sylverstis was planted (field B) acidophilous species among mesophilous forest species were noted. This process of acidification of humus layer is induced by the fall of needles of pines and it has not been observed in communities with planted Fagus sylvatica (field A). It was found that previous mining activities now affect the secondary succession in the forest communities of northern part of the Małopolska Upland because they have created new habitats where process of forming mesophilous phytocoenoses was observed. Accordingly, former human activity leads to the increase in local biodiversity. On the other side current forest management can reduce this effect as a result of planting tree species which acidify these fertile habitats and suppressed the occurrence of mesophilous forest species, what, by contrast, decrease the species richness.

Seslerio uliginosae-Scorzoneretum purpureae is the only xerothermic community of the Festuco-Brometea class, where a rare species known as Sesleria uliginosa occurs in Poland. A couple of sites hosting this association in the Nida Basin were described in the 1920s and 1950s. All these stands are now situated in the areas designated as xerothermic nature reserves. The study aimed at describing the present-day characteristics of this rare association, the most likely being endemic in Poland, as well as the changes that have occurred in it. The species diversity and the contribution of xerothermic plants have decreased significantly in terms of their number and cover coefficient. Some of the diagnostic species of the association have become extremely rare. Sesleria uliginosa is the only one without visible changes in their dominant position in the community. Mosses, that have played a significant role before, were among the vanished species. At the same time, an increase in number and cover of mesophilous meadows species was observed. Mesophilous grasses belong to the group of species growing in significance in the phytocoenoses. The observed changes in species composition were reflected in a statistically significant increase of nitrogen indicator value. The slow process of succession observed in the Seslerio-Scorzoneretum purpureae could be attributed to the lack of appropriate land use, e.g. mowing and grazing that have been ceased in the nature reserves.
