TRÁVNÍČEK B. (2000): Notes on the taxonomy of Pseudolysimachion longifolium complex (Scrophulariaceae). – Thaiszia – J. Bot. 10: 1-26. – ISSN 1210-0420.
Abstract: The taxonomic evaluation of the Pseudolysimachion longifolium complex revealed differences between western (i. e., European and W Asian) populations and the other Asian plants. The examination of lectotype specimens of Veronica longifolia L. (? Pseudolysimachion longifolium (L.) Opiz) and Veronica maritima L. (? Pseudolysimachion maritimum (L.) Á. & D. Löve) showed that the former name refers to the eastern populations whilst the latter belongs to the European/W Asian plants. The recognition of two subspecies within Pseudolysimachion maritimum is shown to be doubtful. Taxonomic position of Pseudolysimachion septentrionale (Boriss.) Á. & D. Löve and P. taigischense (Stepanov) Holub is discussed.
MARTÍN MOSQUERO M. A., JUAN R., PASTOR J. (2000): Morphological and anatomical studies on nutlets of Stachys (Lamiaceae) from south-west Spain. – Thaiszia – J. Bot. 10: 27-38. – ISSN 1210-0420.
Abstract: Scaning electron microscope and light microscope examinations of Stachys‘ nutlets features from south-west Spain have been made. Morphological and anatomical studies have shown that these taxa can be differentiated on the basis of nutlet features. Nutlets of different taxa are described, illustrated and compared. A key to distinguish the different taxa is provided.
DANILOV R. A., PASCHENKO M. N. & EKELUND N. G. A. (2000): The influence of beavers on phytoplankton communities in three forest rivers in the district of St. Petersburg, NW Russia. – Thaiszia – J. Bot. 10: 39-46. – ISSN 1210-0420.
Abstract: Phytoplankton communities were studied at different sampling sites in active beaver (Castor fiber) ponds and after beaver dams in three forest rivers, in August 1998. A total of 24 species of phytoplankton were identified. The taxa present were all broadly distributed and no indicator species were found. For the ponds studied taxa such as Cryptomonas erosa and C. ovata (Cryptophyceae) were the most typical and dominant. Diversity and abundance of phytoplankton species were, in all rivers studied, much higher in the beaver ponds (with the highest values in the beaver outlets) than downstream of the ponds. Cluster analyses based on the phytoplankton data did not allow a clear distinction between the sampling sites in the ponds, in beavers outlets or downstream of the ponds. The results obtained did not indicate any significant patterns in phytoplankton species distribution related to the beaver ponds. The only pattern detected was the total absence of Cryptophyceae downstream of the ponds in all three rivers investigated.
BLANÁR D. & ŠOLTÉS R. (2000): The glacial relic moss species Helodium blandowii in the Veporské vrchy Hills (Slovakia). – Thaiszia – J. Bot. 10: 47-51. – ISSN 1210-0420.
Abstract: During a botanical trip to Veporské vrchy on October, 21, 1999, Helodium blandowii, a glacial moss relic species was found. The species occurs in a minerotrophic fen near the settlement of Pohronská Polhora. This is the most southerly occurence in Slovakia.
GREJTOVSKÝ A., MÁRTONFI P. & ELIAŠOVÁ A. (2000): Soil chemistry data for 533 Central European vascular plant taxa. – Thaiszia – J. Bot. 10: 53-92. – ISSN 1210-0420.
Abstract: Nine soil chemistry characters (pH, carbonate content, oxidisable carbon content, total nitrogen content and the content of available mineral nutrients P, K, Ca, Mg, Na) were studied for 533 taxa of vascular plants on 47 localities from Slovakia, Czech Republic, Hungary and Romania. For 200 taxa occurring on at least 3 localities basic statistic data (minimum, maximum, average, coefficient of variation) are presented.
KUČERA V. (2001): Erysiphales in the valley of the river Vydrica (Malé Karpaty Mts.). – Thaiszia – J. Bot. 10: 101-110. – ISSN 1210-0420.
Abstract: Forty-two taxa of powdery mildew (Erysiphales) have been recorded in the valley of the river Vydrica (Male Karpaty Mts.): Arthrocladiella (1), Blumeria (1), Erysiphe (20), Microsphaera (9), Phyllactinia (2), Podosphaera (1), Sawadaea (2), Sphaerotheca (4), Uncinula (1), and one anamorph in Oidium (1). Variability of biometric characters of cleistothecia, asci, ascospores, konidia are presented. Listed species were associated with 84 taxa of vascular plants; four of them represent new host plants for powdery mildews in Slovakia.
ŠOLTÉS R. (2001): The arcto-alpine moss Andreaea obovata Thed. in the Tatra Mts., Slovakia. – Thaiszia – J. Bot. 10: 111-114. – ISSN 1210-0420.
Abstract: The species Andreaea obovata was recorded on the summit rocks of Lomnický štít peak in 1880′-s. Now, nearly 120 years later, the species has been refound. The summit area was heavily damaged due to construction of a rope railvay. The species has survived on undamaged, rather inaccessible slopes in the summit area. The phytocoenological relevé is included.
STARMÜHLER W. & MITKA J. (2001): Systematics and chorology of Aconitum sect. Napellus (Ranunculaceae) and its hybrids in the Northern and Forest Carpathians. – Thaiszia – J. Bot. 10: 115-136. – ISSN 1210-0420.
Abstract: The genus Aconitum is distributed in the Northern and Forest Carpathians with 7 species, including the infraspecific taxa and hybrids with 23 taxa. A new combination is A. firmum subsp. maninense. This subspecies is also stated in Poland for the first time. New taxa described here are A. firmum nsubsp. paxii, A. firmum subsp. firmum var. portae-ferratae, A. firmum nsubsp. zapalowiczii, A. ×lengyelii nsubsp. walasii. Following names are typified in this article: A. bucovinense, A. firmum, A. firmum subsp. fissurae, A. ×lengyelii, A. ×nanum. All taxa are described, their types are stated and a key for the determination is given.
