Cyanobaktérie a riasy štrkoviskového jazera Štrkovec v Bratislave
Cyanobacteria and algae of the gravel-pit lake Štrkovec in Bratislava
Species composition of the phytoplankton and phytobenthos of the gravel-pit lake Štrkovec in Bratislava, W Slovakia, was studied in 1998. Altogether 23 species and infraspecific taxa of prokaryotic Cyanobacteria and 281 taxa of different groups of microscopic algae were determined. 7 species (marked with an asterisk in the list) are first records for the territory of the Slovak Republic – Johanesbabtistia pellucida, Asterocystis smaragdina, Navicula pseudanglica, Navicula pseudolanceolata, Nitzschia gessneri, Nitzschia incognita, Coccomonas eberi. Planktic cyanobacterial water blooms were formed mainly by Snowella litoralis and by species of the genus Microcystis (M. aeruginosa, M. flos-aquae, M. viridis), benthic water bloom (Oscillatorietum) mainly by Oscillatoria limosa and O. princeps.
Druhové zloženie a biomasa fytoplanktónu rieky Hron
Phytoplankton species composition and biomass of the Hron river
During investigations of species composition of phytoplankton of the Hron river (Slovakia), from 1992 to 1998, 138 genera, 424 species, 1 subspecies, 22 non-type varieties and 3 forms belonging to Cyanophyta/Cyanobacteria and different groups of microscopic algae were determined. First records for the algal flora of the Slovak Republic are (marked with an asterisk in the list): Anabaenopsis milleri (Cyanophyta/Cyanobacteria), Chantransia chalybaea (Rhodophyta), Cyclotella fottii, Achnanthes rosenstockii, Navicula porifera var. opportuna, Pinnularia borealis var. rectangularis, (Bacillariophyceae), Ceratium furcoides (Dinophyceae), Menoidium curvatum (Euglenophyceae), Pteromonas limnetica (Volvocales) and Schroederia indica (Chlorococcales). During the investigation period the abundance of the phytoplankton in the confluence of the Hron river decreased rapidly. The abundance varied in the range of 40–70 000 cells per 1 ml. In 1990–1998 the chlorophyll-a concentrations oscillated from 0.5 mg.m to 129.0 mg.m. Time series show decreasing trend in the period of 1990–1996, while concentration of chlorophyll-a increased in the last two years.
Mikroskopické huby izolované z depozitov Slovenského národného múzea v Martine
Microscopic fungi isolated from the depositories of the Slovak National Museum in Martin
In 1996–1997 occurrence of microscopic soil fungi in the depositories of sculptures and paintings (canvases and frames) at the Slovak National Museum (SNM), Martin, was studied. For the cultivation of the fungi the following media were used: Czapek-Dox, Sabouraud, malt-extract and DG 18. Microscopic fungi of the genera Alternaria, Aspergillus, Aureobasidium, Cephalosporium, Chaetomium, Cladosporium, Fusarium, Mucor, Paecilomyces, Trichoderma, Cephalosporium, Verticillium and Scopulariopsis were isolated by sediment plate method and wipping off from the surface with steril cotton plugs. The representants of the genus Aspergillus were the most frequent on the wooden sculptures, those of the genera Penicillium, Cladosporium, Aureobasidium and Trichoderma were less abundant. The species of the genera Aspergillus, Penicillium, Chaetomium and Aureobasidium dominated on the paintings.

Cladonia rei (lichenizované askomycéty) na stanovištiach kontaminovaných imisiami z Kovohút Krompachy (SV Slovensko)
Cladonia rei (lichenized Ascomycotina) on heavy metal-contaminated habitats near copper smelters at Krompachy (NE Slovakia)
Cladonia rei, not very common lichen species in Slovakia, was found in the vicinity of copper smelters at Krompachy, growing on bare acid soil, amongst the moss Ceratodon purpureus, in habitats strongly affected by airborne heavy metals and SO2. All vascular plants, except for a few hardly surviving species of severely damaged shrubs and trees, have disappeared from these habitats. The lichen was very abundant, showing apparently a high tolerance towards the pollution.

Je okolie Kremnice miestom najstaršieho výskytu čarodejky škvrnitej Mimulus guttatus DC.) na Slovensku?
Kremnica – the oldest place of occurrence of the Common Monkey Flower (Mimulus guttatus DC.) in Slovakia?
Data on the occurrence of Mimulus guttatus DC. in Slovakia are given. There is some uncertainty about the oldest place of occurrence of the species in Slovakia, as the two oldest records, namely from 1881 from the vicinity of the town of Kremnica (the Kremnické vrchy Mts) and that of 1884 from nearby the town of Hnilec are unclear. The first reliable record dates back to 1885 when the species was collected nearby Kremnica. The presented data complete the account of localities of the species published in a recent volume of the Flora of Slovakia (“Flóra Slovenska V/2”).

Globularia bisnagarica L. (Globulariaceae) roste u Kysaku (V Slovensko)
Globularia bisnagarica L. (Globulariaceae) grows near Kysak village (E Slovakia)
New locality was found near Kysak village and with regard to unsure reference of Hrabětová-Uhrová (1953) it is confirmation of the old Šmarda´s information. The species grows on dolomitic hills with xerotermous forest-steppe coenoses and Festuca - Brometea communities. The plants were found in 9 groups (8 of them were sociologically analysed), in number ca. 35 plants, however, probably only ca. 20 genets. The species is very threatened here due to possible extinction caused by environmental fluctuations and inbreeding depression in population.
Poznámky k historickému výskytu kručinôčky krídlatej (Genistella sagittalis) v širšom okolí Bratislavy
Notes on the historical occurence of Genistella sagittalis in broader vicinity of Bratislava
During revision of the distribution of Genistella sagittalis in the West and East Carpathians interesting data about its occurrence in broader vicinity of Bratislava were found. The first locality is situated on the right bank of the Danube river near Mosonmagyaróvár (Hungary), only 30 km from the center of Bratislava. The herbarium specimens collected in 1924 by J. Černý from the village Kuchyňa (SW Slovakia) give the first concrete data about its occurrence in Slovakia. The author of the contribution considers about mention species as allochtoneous for Slovak flora.
Allium paniculatum L. na Slovensku
Allium paniculatum L. in Slovakia
Allium paniculatum L. belongs among the rare and critically endangered species of the flora of Slovakia. The northern boundary of the distribution area of the species passes through Slovakia. Up to now it was known only from the Podunajská nížina lowland. Present study enabled to extend and update the knowledge of the distribution. It was found at five localities in the Podunajská nížina lowland, at one locality in the Burda Mts and at one locality near the village Hostišovce. Recently the occurrence of A. paniculatum in Slovakia was confirmed only at two localities: the first one in the Podunajská nížina lowland on the hill Kurta near the village Svätý Peter and the second one on the hill Veľká Lysá near the village Hostišovce; this is the northernmost known locality of the species in Slovakia.
Synantropizácia Martinského dubového lesa
Synanthropization of the oak forest Martinský les
Oak woods in Slovakia were drastically reduced during past years. Martinský les is a unique area in SW Slovakia with numerous oak species. Many synanthropic species have infiltrated here from surrounding fields and changed its original floristic composition. Thus occurrence of 41 archeophytes, 9 hemerophytes, 9 neophytes as well as of further 21 alien taxa of questionable categorisation, were recorded here. Mainly Ailanthus altissima, Amaranthus retroflexus, Conyza canadensis, Datura stramonium, Robinia pseudoacacia, Stenactis annua subsp. septentrionalis, Convolvulus arvensis, Descurainia sophia, Echinochloa crus-galli and Equisetum arvense are potentially dangerous.

A new association Festuco tatrae-Pinetum ass. nova of the alliance Pulsatillo slavicae-Pinion Fajmonová 1978 from the Western Carpathians – Nízke Tatry Mts, Chočské vrchy Mts, Malá Fatra Mts and Západné Tatry Mts, is described and its synmorphology, synecology, synchorology, syntaxonomy is given. In the framework of the variability of the association, a new subassociations – Festuco tatrae-Pinetum teucrietosum montani subass. nova from dolomites and Festuco tatrae-Pinetum laricetosum subass. nova from limestone, both with two thermovariants, are presented too.
Diferenciácia spoločenstiev s dominantným Helianthus tuberosus s. l. na Slovensku
Differentiation of Helianthus tuberosus s. l. dominanted communities in Slovakia
Numerical classification of 25 relevés over Slovakia was the basis for separation of Helianthus tuberosus s. l. dominated stands into two communities: community with Heliathus tuberosus (Onopordetalia) and community with Helianthus tuberosus (Senecionion fluviatilis). Different floristic composition of the communities is a result of both habitat and ecological differences.
K rozšíreniu rastlín na vodných a močiarnych nelesných biotopoch v alúviu Moravy (úsek Devín-Brodské)
To the occurence of plants within the non-forested wetland habitats along the Morava river floodplain (part Devín-Brodské)
Running and standing water, river arms, oxbows and wet meadows along the Morava river represent a unique system of wetland habitats. The ecological conditions and frequency of plants were characterised within 25 representative wetland localities from the mouth (Devín) to the 80 rkm (Brodské). The area is included in the Ramsar list. A great number of endangered and rare plants are found here, such as Leucojum aestivum, Lindernia procumbens, Stratiotes aloides, Wolffia arrhiza.
