Adedeji O. (2012): Systematic significance of trichomes and foliar epidermal morphology in the species of Stachytarpheta Vahl. (Verbenaceae) from Nigeria. – Thaiszia – J. Bot. 22 (1): 1-31. – ISSN 1210-0420.

Abstract: The foliar epidermal surfaces, leaf venation and trichome studies of different plant parts of the three species of Stachytarpheta Vahl. family Verbenaceae found in Nigeria were studied and compared. Observations were carried out by light microscope. Across the genus, leaves were amphistomatic and amphitrichomic. Qualitative foliar anatomical characters found to be most useful in species delimitation were stomata shape, trichome types, anticlinal cell wall pattern on adaxial surface and veinlet termination number. Quantitative characters of taxonomic importance, as revealed by analysis of variance (ANOVA) and duncan multiple range test (DMRT) were length and width of epidermal cells, stomatal index and stomatal size. Two trichome types, glandular and non-glandular were observed in the genus. The non-glandular trichomes were of higher numerical density on adaxial surface than on abaxial surface. The implication of this in terms of protection against excessive radiation, chemical control strategies and higher temperatures was mentioned. On the abaxial surface however, the glandular secreting trichomes were more numerically than the non-glandular. The importance of the preponderance of these trichomes on the abaxial surface in relation to the role they play in the protection of essential oils earlier reported in the family and genus, was discussed. Stomatal abnormalities observed in the genus were, contiguous stomata arrangement in S. cayennensis and aborted guard cells in S. indica. Leaf venation type in the genus is pinnate craspedodromous simple 2 with recurved secondary veins. Trichome distribution survey in the different plant parts revealed specific combination types that would be useful in species delimitation, especially in fragmentary parts identification.

Abstract: The article brings the numerical classification of the 27 original phytocoenological relevés of the European hazel stands from the boundary of the Turčianska kotlina Basin and adjacent mountain ranges (Kremnické vrchy Mts, Žiar Mts, Krivánska Malá Fatra Mts, Veľká Fatra Mts). Their comparison with original diagnoses of relevant syntaxa resulted to classification of all relevés within the association Prenantho purpurei-Coryletum (Kulczyński 1928) Kliment et Jarolímek 2012. The most important ecological factor determining floristical composition of the individual stands and consequently their classification is geological bedrock (andesite and marly limestone), which overshadow influence of the altitude.

Kučera P. (2012): Remarks on the intramontane continentality of the Western Carpathians defined by the absence of Fagus sylvatica. – Thaiszia – J. Bot. 22 (1): 65-82. – ISSN 1210-0420.

Abstract: A number of authors (e.g. Tschermak, Svoboda, Zlatník) stated that a zone of continental climate without Fagus sylvatica was present between the Tatry Mts and the Nízke Tatry Mts, in the so-called central part of the Western Carpathians. However, recent research confirmed the autochthonous occurrence of Fagus within the Podtatranská kotlina and the occurrence of Fagus stands even on non-carbonate substrates. Hence, both the reason and the way of differentiation of the intramontane continentality supposed exclusively for this region of the Western Carpathians should be re-evaluated.

Abstract: In the present study, abundant new localities of Centaurea jacea subsp. angustifolia Gremli have been found in the southern part of Nida river Basin, belonging to Małopolska Upland region of Poland. Distribution of this subspecies in Poland has been not elaborated so far. Revision of specimens from Polish herbaria revealed that this subspecies was collected previously in Wały reserve, situated close to the present findings. Moreover, the species was found in the past in Silesia region, as well as at two localities in the north-west of Poland. Probably, all the localities outside Nida Basin were of synanthropic origin. The distribution map of C. jacea subsp. angustifolia in Poland is presented.

Vološčuk I. (2012): Changes in forest phytodiversity caused by alien woody plants in Štiavnické vrchy Mts. – Thaiszia – J. Bot. 22 (2): 105-119. – ISSN 1210-0420.

Abstract: Phytodiversity is the foundation of life on Earth. It underpins the functionig of ecosystems from which the human derive essential products and services (known as ecosystem services), such as oxygen, food, fresh water and medicine. Healthy phytodiversity is essential to human wellbeing, sustainable development, and poverty reduction. The introduction of alien woody species in forest ecosystems has been caused some problems and has, at the same time, substantially changed the phytodiversity as well as the aesthetic harmony of the landscape. The alien woody plants in Štiavnické vrchy Mts. was introduced on the end of 19. and the beginning of 20. century, thanks to the Professors of the Mining and Forestry Academy in Banská Štiavnica City. The goal of introduction was growth and production study for scientific purpose, for forestry teaching processes and for forest management. In 2009 on the territory of the School Forest District Kysihýbel near the Banská Štiavnica City was founded 10 research plots in the oak – beech vegetation belt with the alien woody plants: Pseudotsuga menziesii, Pinus strobus, Picea abies, Abies alba, Larix decidua, Pinus sylvestris, Pinus nigra, Robinia pseudoacacia. In the comparative (reference) plots the native trees Quercus petraea and Fagus sylvatica has been dominant presentation. Especially Robinia pseudoacacia woods radical change the phytodiversity of the orginal forest association. There were evaluated changes in phytodiversity caused by alien woody plants using ecological spectrum of phytocoenoses and ecological demands of plants on the basic environmental factors – light, temperature, continentality, moisture, soil reaction and nitrogen in soil. The similarity of research plots was evaluated by statictic methods.

Bomanowska A. & Adamowski W. (2012): Alien plant species in secondary succession. – Thaiszia – J. Bot. 22 (2): 121-141. – ISSN 1210-0420.

Abstract: The behaviour of geographically alien plants in the course of secondary succession on an abandoned field and an unmown meadow in the Experimental Garden of BGS was analysed. Amongst 226 species found on the abandoned field were: 36 archaeophytes and 31 kenophytes. Over 50% of the archaeophytes retreated after six years of observation, and their cover decreased from 20% to 2%. Only vetches (Vicia angustifolia, V. hirsuta, V. tetrasperma) thrived for longer on the plot. The cover of kenophytes decreased from 4% to zero in fourth year of observation and was insignificant up to 19-th year of observation. The first woody kenophyte, Pinus strobus, emerged in 15-th year of observation. In recent years the cover of kenophytes increased to 3%. At the moment Acer pseudoplatanus, Crataegus sp. and Padus serotina have the highest frequency amongst woody aliens in the herb layer. Ten kenophytes entered the shrub layer, although their cover is still negligible. On the unmown meadow amongst 198 taxa were 27 archaeophytes and 24 kenophytes. The number of archaeophytes fell from 24 in the first year of observation to 5 in the sixth, and cover from 4% to less than 1%. Archaeophytes were seen for the last time in 34-th year of observation. The cover of kenophytes fell from less than 1% to almost zero in the third year. Since 19-th year of observation the cover of kenophytes in the herb layer has been rising, recently reaching about 2%. The first woody kenophyte, Malus domestica, was established in third year of observation. Up to now 7 kenophytes have entered the shrub layer. Their cover recently reached about 5%. In 15-th year of observation Malus domestica, and in 29-th year Tilia platyphyllos entered the tree layer. Their cover recently reached about 10%. The different behaviour of archaeophytes and kenophytes is, at least partially, the result of the prevalence of different ecological and biological peculiarities (e.g. life forms) of these groups of species.

Kirpluk I. (2012): The most recent alien species of the ruderal flora in the abandoned villages of the Kampinos National Park (Central Poland). – Thaiszia – J. Bot. 22 (2): 143-153. – ISSN 1210-0420.

Abstract: Field research on the ruderal flora of 15 abandoned villages in the Kampinos National Park revealed that among ca. 550 vascular plant species identified 11% represent the newest flora settlers – the epoecophytes. The number of epoecophytes in particular villages varied from 16 to 31. Only 5 species were present in all the villages: Amaranthus retroflexus, Conyza canadensis, Galinsoga parviflora, Robinia pseudoacacia, and Syringa vulgaris. Distribution of epoecophytes in particular villages was generally low. Only Conyza canadensis, Robinia pseudoacacia and Syringa vulgaris were common. The observed phenomenon results from the ongoing intensive depopulation process in the majority of the villages followed by decreased anthropopressure. The desynanthropization of the flora seems to have little impact on penetration by invasive species such as Echinocystis lobata and Impatiens glandulifera. Among the rare and endangered species of synanthropic flora of the Kampinos National Park two epoecophytes were found: Anthemis ruthenica and Camelina microcarpa.

Abstract: The paper deals with the locality of the spa forest park Dudince in perspective of allergenic trees. The aim of our investigation was to find out what the percentage of the tree species composition in three storeys is (shrub layer, subordinate tree layer, and above-level) of the spa forest park. Furthermore, we tried to determine the origin, way of pollination and potential of trees causing pollinosis. Only pollen of four species was characterized as highly allergenic, while only pollen of the birch (Betula pendula) achieves the highest level of allergenic potential. From the results we can conclude that the tree species composition of the spa forest park Dudince is suitable for the recovery of the patients.

Abstract: In the year 2012 we have compared the occurrence of invasive woody plant species within the area of Botanical Garden of PJŠU in Košice with their occurrence in the year 2008. It was connected with application of the series of sanation measures to suppress the spread of invasive woody plant species. Following taxa were the subject of the research: Robinia pseudoacacia L., Ailanthus altisima (Mill.) Swingle, Negundo aceroides Moench., Amorpha fruticosa and Parthenocissus quinquefolia L.. Parameters of individual woody plants were measured: stem diameter at the height of 1,30 m (d1,3) in cm and total height in meters. The occurrence was marked on the schematic map and the photodocumentation of plants was obtained. The research revealed that, based on abundance, Robinia pseudoacacia L. is dominant there due to former intentional planting of black locust individuals for anti erosion and soil stabilization purposes (fixing ravines, areas with critical slope and shallow soils). The goal of several former specific plantings was completed, sporadically the natural decline of older trees takes place but in many sites the considerable root and trunk sprouting capacity is manifested and it makes the forest park maintainance more difficult. The enormous invasive potential is manifested by the species Ailanthus altissima L. which dominates also in urban plantings as very aggressive and rapidly spreading species. In the reduction of invasive species abundance, only the yearly repeated phytotechnical measures are really successful. Occasional elimination of woody plant individuals leads only to a time-limited positive effect and the result is a support of trunk and root sprouting capacity and consequently to the formation of hardly manageable compact stand of woody plants.

Abstract: In order to keep biological diversity there are many protected areas, not only in Slovakia. Xeric sand calcareous grasslands and Pannonic sand steppes belong to the most important biotopes with European meaning. These are sand societies on inland flying sand with a specific grassy-herbaceous constitution. The purpose of the project of cultivation of Colchicum arenarium and Alkanna tinctoria in the terms of ex-situ from the diasporas was to cultivate individuals in artificial conditions and consecutively to plant them into the areas with natural presence in Čenkovska step and Čenkovska lesostep. in the register Mužla in region of Nove Zamky. The whole project was realized in cooperation with the National Nature Conservation of the Slovak Republic.

Abstract: The park and non-park objects in 90 settlements of Levice district were searched. Together 70 objects situated in 48 settlements (villages or towns) were found during inventory of woody species in May – September 2011. The results showed that in 90 settlements of Levice district there are situated 70 park and non-park objects. The total number of woody species fluctuated between 4 and 111 pieces, in Čajkov park and Levice city park, respectively. The percentage of introduced, autochthonous,  broadleaves and coniferous woody taxa was also determined. In the studied objects there dominated mostly introduced woody taxa and broadleaves.

Suvák M., Gregorek R. & Pľuchtová M. (2012): Actual and potential role of parasitoids (Hymenoptera: Eulophidae) in control of water-lily beetle Galerucella nymphaeae (Coleoptera: Chrysomelidae) in conditions of Botanical Garden of P.J. Šafárik University in Košice (Slovakia). – Thaiszia – J. Bot. 22 (2): 217-242. – ISSN 1210-0420.

Abstract: In the Botanical Garden of P.J. Šafárik University in Košice the water-lily beetle Gallerucella nymphaeae has been causing serious problems in growing ornamental cultivars of waterlilies Nymphaea x hybrida. When looking for possibilities of natural regulation of the beetle, the occurrence of egg parasitoids has been found with predominance of Oomyzus gallerucae. Later on, the occurrence of Aprostocetus celtidis has been noticed occasionally and the structure of hatching results suggests the possibility of its hyperparasitic relationship with O. gallerucae. This is the first record of association of these chalcid wasps to G. nymphaeae as well as the first ever registered species of parasitoids of the water-lily beetle eggs. During summer of 2012, the parasitation rate had been watched in three consequent extensive sampling events. The rate of parasitized eggs from individual basins varied from 2 % to 29 %, 12% being average. To compare, and potentially to enrich the spectrum of parasitoids in biological control of water-lily beetles in BG PJŠU, the nearest known natural habitats with occurrence of G. nymphaeae were visited near Klin nad Bodrogom. The samples of water-lily beetles provided pupal parasitoids – species Asecodes lucens and Tetrastichus clito, which have not been found from Košice samples yet. In the case of T. clito, it is another first ever record of parasitic relationship of this species with the water-lily beetle G. nymphaeae. From the faunistic point of view, all four species of chalcid wasps were recorded in Slovakia for the first time. Three newly registered associates (O. gallerucae, A. celtidis and T. clito) of G. nymphaeae will need further evaluation. According to literary sources, the typical regulator of the water-lily beetle seems to be A. lucens. Its introduction to BG PJŠU could significantly help in the biological protection of water-lilies grown there. The possibility of wider application of all parasitoids should be studied with regard to occurrence of alternative hosts on vegetation around the basins. As the registered eulophid species behave as generalist parasitoids, the differences in their chrysomelid hosts (and other parasitoids in the case of A. celtidis) and associated food plants should be taken into account in next research there.

Abstract: Occurrence of invasive plant species was analysed in semi-natural and anthropogenic habitats in the surroundings of the spa town Piešťany (Western Slovakia) using the floristic data from 96 sites gathered during the years 2009–2011. Together, 102 alien species (19.6 % of the total flora of area) were recorded, among them 71.6 % archeophytes and 28.4 % neophytes. Non-native plant species were widespread unevenly in the area. The highest number of alien species was found in subxerophilous shrubs and hedges between arable fields (48 taxa), in small enclaves of floodplain forest remnants (36 taxa) and in overgrown alluvial meadows (34 taxa), and the smallest number was found in the areas closer to natural habitats, e.g. lakes, gravel bars, glades, abandoned orchards and in various types of deciduous forests and submontane grasslands (1–9). Concerning total occurrence of alien species in individual habitats as well as their average numbers, more invasive species occurred in the Váh river alluvium than in the Považský Inovec Mts. The habitats in the alluvium of the river Váh were characterized also by higher representation of invasive neophytes, which demonstrates a significant role of water streams and disturbed river bank habitats in spreading of these species in landscape.
