Cyanobaktérie a riasy malej eutrofnej vodnej nádrže v Modre pdf
Cyanobacteria and algae of a small eutrophic water reservoir at Modra (W Slovakia)
p. 129–135

Abstract: Diversity of cyanobacteria/cyanophytes and algae in a small eutrophic water reservoir at Modra (W Slovakia) was studied in 2008–2009. During this period, 25 genera with 44 species of Cyanobacteria/Cyanophytes, and 67 genera with 102 species and infraspecific taxa of different groups of microscopic algae were identified in the phytoplankton and phytobenthos samples. Five taxa are first records for the territory of the Slovak Republic, viz. two species of cyanobacteria: Synechococcus mucicola Joosten, Synechocystis endophytica (G.M.Smith) Joosten, and three species of green algae: Nautococcus mamillatus Korshikov, Bicuspidella incus Pascher, Desma-tractum indutum Pascher. Phytoplankton of the water basin was mostly strongly dominated by green colonial alga Golenkiniopsis longispina that caused intensive green colouration of the water namely in summer. However, in some months in 2009 other microorganisms prevailed, e.g. in March and April diatoms, from October to December of the cyanophyte species Aphanocapsa delicatissima having cell of picoplanktic size.

Keywords: Central Europe, diversity, man-made water reservoir, phototrophic microorganisms.

Machorasty historických cintorínov vo vybran ých mestách strednej Európy pdf
Bryophytes on historical cemeteries of selected cities in Central Europe
s. 137–145

Abstract: With increase of urbanisation grows the importance of urban green spaces – parks, cemeteries, gardens, for biodiversity conservation. To obtain information on a poorly-studied group – bryophytes, we observed the species composition on 5 historical cemeteries, located in Vienna, Bratislava and Dolný Kubín (Central Europe). Altogether, a total of 67 bryophyte species was recorded (4 species of Marchantiophyta, 63 species of Bryophyta); epigeic substrates supported the highest species richness (46 bryopyhtes); 41 species were found on rocky substrates, just 18 bryophytes grow on living trees and 5 were found on dead wood.

Keywords: Bryophyte diversity, Central Europe, green space, urban environment.

Významné floristické refúgium na Krížnej vo Veľkej Fatre pdf
The important floristic refugium on Krížna Mt. (Veľká Fatra Mts)
s. 157–161

Abstract: The paper offers new and additional information about distribution of some rare plant species at the end of Rybô valley in Veľká Fatra Mts. The distribution and abundance of the three alpine representatives of the genus Astragalus L. has been studied in the field in July 2008. The most abundant one, A. penduliflorus, occupies convex crests with relatively homogenic surface. The presence of the species which is found more rarely – A. australis is tied to rocks and stony places formed by the snow and water erosion. A. alpinus occurs very infrequently in the moist erosive trenches. Discoveries of the species Crepis sibirica and Phelipanche purpurea emphasize floristic importance of the studied site. While the endangered species of Slovak flora Crepis sibirica has again been discovered in Krížna massif after 85 years, Phelipanche purpurea has only been noticed in the border parts of Veľká Fatra Mts more than 100 years ago.

Keywords: Crepis sibirica, distribution, Phelipanche purpurea.

K premenlivosti Pinguicula vulgaris v Západných Karpatoch na území Slovenska pdf
On the variability of Pinguicula vulgaris in the Western Carpathians in the territory of Slovakia
s. 175–181

Abstract: The author describes autochtonous original variability of the flower colour of natural populations of Pinguicula vulgaris L. from the Slovak part of the Western Carpathians. On the basis of wider living material she diferentiated 5 colour types of group variability of the flower: (1) white corolla, (2) bicolour corolla with all lobes white, (3) bicolour corolla with bottom lobes white, (4) bicolour corolla with all lobes blue-violet, (5) blue-violet corolla.

Keywords: Pinguicula vulgaris, variability, Western Carpathians.

Charakteristika asociácie Luzulo albidae-Quercetum petraeae v Štiavnických vrchoch (stredné Slovensko) pdf
Characteristic of the association Luzulo albidae-Quercetum petraea e in the Štiavnické vrchy Mts (central Slovakia)
s. 203–213

Abstract: The paper reports the results of a short phytosociological research in the acidophilous forest communities Luzulo albidae-Quercetum petraeae from the Štiavnické vrchy Mts. In addition to the species composition, special attention was given to synmorphological and synecological characteristics. The community is floristically relatively poor with regular occurrence of oligotrophic and acidophilous species. The stands are situated mainly in ridge parts on shallow soils with minimum water retention capacity. T he diagnostic species (Avenella flexuosa, Genista pilosa, Quercus petraea agg.) have been defined based on the results of the analysis of forest vegetation data obtained exclusively from the studied region.

Keywords: acidophilous oak forests, Genisto germanicae-Quercion, Luzula luzuloides, phyto-sociology, species composition, Western Carphathians.

Rastlinné spoločenstvá zatienených skál na Muránskej planine a vo Veľkej Fatre pdf
Plant communities of the shaded rocks in the Muránska planina Mts and Veľká Fatra Mts
s. 215–238

Abstract: Pioneer vegetation of the shaded rocks in the Veľká Fatra Mts, and Muránska planina Mts (Central Slovakia) was studied using phytosociological methods of the zürich-montpellier approach. Four plant communities were found and documented by relevés: Cystopteridetum fragilis, and Bellidiastro michelii-Campanuletum cochleariifoliae (all. Cystopteridion), both occurring on limestone bedrock, while the rare community Woodsio ilvensis-Asplenietum septentrionalis (all. Asplenion septentrionalis) growing only on the andesites and andesite tuffs and the association Asplenio-Polypodietum (all. Hypno-Polypodion vulgaris) preferring mostly granite bedrock. Our analysis shows, that there are not any significant differences between species composition of the communities in both studied areas, although a moderate geographical vicarisation of two variants of the most variable association Cystopteridetum fragilis is remarkable.

Keywords: andesite, Asplenietea trichomanis, granite, limestone, pioneer communities, rocky walls and cliffs.

Aplikácia metód modelovania oslnenia georeliéfu, topoklímy a výmoľovej erózie v prostredí GIS (na príklade Devínskej Kobyly) pdf
Application of methods for modelling terrain insolation , topoclimate and gully erosion in GIS: a case study of the Devínska Kobyla Mt.
s. 253–273

Abstract: This work focuses on evaluation of the landscape potential in the area of the Devínska Kobyla Mountain. It is important to understand the topoclimatic differences of thermal and hygric characteristics with regard to this relationship. We use methods of quantitative planar estimations of the topoclimatic characteristics, calculations of insolation dynamics from a digital terrain model. The final evaluation includes geomorphometric fields – elevation and the derived characteristics. Area is outstanding by its morphodynamics and also sufficient amount of data required for natural hazards assessment. Gully erosion is a complex phenomenon associated with extreme rainfall events and anthropic land use changes. This modelling can be considered a definitive product of the research ready to be employed in the management of this valuable site.

Keywords: Devínska Kobyla Mt., digital terrain model, GIS, gully erosion, landscape potential, solar radiation.
