Public Citation [article]  inPreslia > 75 (2003) . - 193-222 Titre : Check- and Red List of bryophytes of the Czech Republic (2003) Type de document : Électronique Auteurs : Jan Kučera ; Jiří Váňa (1940-2018) Année de publication : 2003 Article en page(s) : 193-222 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Bryophytes [CBNPMP-Thématique] Livre Rouge [CBNPMP-Géographique] République Tchèque Résumé : The second version of the checklist and Red List of bryophytes of the Czech Republic is provided. Generally accepted infraspecific taxa have been incorporated into the checklist for the first time. With respect to the Red List, IUCN criteria version 3.1 has been adopted for evaluation of taxa, and the criteria used for listing in the respective categories are listed under each red-listed taxon. Taxa without recent localities and those where extinction has not been proven are listed as a subset of DD taxa. Little known and rare non-threatened taxa with incomplete knowledge of distribution which are worthy of further investigation are listed on the so-called attention list. In total, 849 species plus 5 subspecies and 19 varieties have been accepted. 23 other historically reported species and one variety were evaluated as doubtful with respect to unproven but possible occurrence in the territory, and 6 other species with proven occurrence require taxonomic clarification. 43 taxa have been excluded from our flora compared to the last checklist version. 48.6 % of evaluated taxa have been listed in either of the Red List categories (EX (RE), CR, EN, VU, LR or DD), which is comparable to other industrialized regions of Central Europe.

Conyza triloba, new to Europe, and Conyza bonariensis, new to the Czech Republic / Otakar Sida in Preslia, 75 (2003) 

Public Citation [article]  inPreslia > 75 (2003) . - 249-254 Titre : Conyza triloba, new to Europe, and Conyza bonariensis, new to the Czech Republic Type de document : Imprimé Auteurs : Otakar Sida Année de publication : 2003 Article en page(s) : 249-254 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes [CBNPMP-Géographique] République Tchèque Mots-clés : Conyza triloba  Conyza bonariensis  Asteraceae Résumé : Conyza bonariensis (L.) Cronquist and C. triloba Decne. are reported as new alien species to the Czech Republic and Europe, respectively. Conyza bonariensis was collected in 1964 and 1965 in two localities in N Bohemia; the specimens are deposited in PRA. In both cases, the plants were introduced with cotton and occurred in areas of textile factories. Conyza triloba was collected once at the pond in the village of Černivsko in S Bohemia in 1971; the specimen is deposited in PR. The mode of introduction is unknown.

Cyperus eragrostis : a new alien species for the Czech flora and the history of its invasion of Europe / Petr Petrik in Preslia, 75 (2003) 

Public Citation [article]  inPreslia > 75 (2003) . - 17–28 Titre : Cyperus eragrostis : a new alien species for the Czech flora and the history of its invasion of Europe Type de document : Imprimé Auteurs : Petr Petrik Année de publication : 2003 Article en page(s) : 17–28 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes [CBNPMP-Géographique] République Tchèque Mots-clés : Cyperus eragrostis Lam. Résumé : Cyperus eragrostis Lam. was first recorded in the Czech Republic in an empty water reservoir at Jablonec nad Nisou (N Bohemia) in 1999. In this study, herbarium specimens of C. eragrostis in large herbaria in the Czech Republic were revised and the invasion of Europe by this species was reviewed. A brief description of C. eragrostis is given, distribution map of the temporal course of its invasion is presented and the species’ ecology in Europe characterized. Accompanying vegetation and results of the analyses of soil from the site are described. How the plant reached this locality remains unknown. The occurrence was only ephemeral as the only tussock was destroyed when the water reservoir was refilled.

Oenothera coronifera, a new alien species for the Czech flora, and Oenothera stricta, recorded again after nearly two centuries / Stanislav Mihulka in Preslia, 75 (2003) 

Public Citation [article]  inPreslia > 75 (2003) . - 263-270 Titre : Oenothera coronifera, a new alien species for the Czech flora, and Oenothera stricta, recorded again after nearly two centuries Type de document : Imprimé Auteurs : Stanislav Mihulka ; Petr Pyšek ; Antonin Pyšek Année de publication : 2003 Article en page(s) : 263-270 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes [CBNPMP-Géographique] République Tchèque Mots-clés : Oenothera coronifera  Oenothera stricta Ledeb. Résumé : Two species of the North American genus Oenothera are reported as aliens in the Czech Republic. A population of O. coronifera consisting of ca. 30 plants at various phenological stages, from rosettes to flowering plants, was found in 2001 at the railway station in the town of Zliv, district of České Budějovice, S Bohemia. The species was probably introduced via the railway and is the first record of this species for the Czech Republic. A single plant of O. stricta, previously reported from the bank of the Vltava river in Prague, in 1825, was found as a weed in a private garden in the village of Vroutek, district of Louny, N Bohemia, in 2000. This is the second record of this species from the Czech Republic in 175 years. The seed of O. stricta was probably introduced to the site from abroad and the record suggests that the occurrence of casual alien plants is highly unpredictable. It is argued that botanists studying alien plants, given their special interest in sites where these plants occur, may directly contribute to the enrichment of checklists of national alien floras.

Czech national phytosociological database: basic statistics of the available vegetation-plot data / Milan Chytrý in Preslia, 75 (2003) 

Public Citation [article]  inPreslia > 75 (2003) . - 1-15 Titre : Czech national phytosociological database: basic statistics of the available vegetation-plot data Type de document : Imprimé Auteurs : Milan Chytrý (1967-) ; Marie Rafajová Année de publication : 2003 Article en page(s) : 1-15 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Groupements végétaux, phytosociologie [LOTERRE-Biodiversité] Phytosociologie Résumé : The vegetation relevés stored electronically in the Czech National Phytosociological Database are reviewed. The database was established in 1996, with the central database located in the Department of Botany, Masaryk University, Brno (www.sci.muni.cz/botany/database.htm). On 15 November 2002 this central database contained 54,310 relevés from the Czech Republic, collected by 332 authors between 1922–2002. Ca. 54% of the relevés were taken from published papers or monographs, 21% from theses and the rest from various unpublished reports and field-books. These relevés include 1,259,008 records of individual plant species. Territorial coverage of the country by the reléves is irregular as the areas with attractive natural or semi-natural vegetation are more intensively sampled, with gaps in coverage of less attractive or poorly accessible areas. Most relevés are of broad-leaved deciduous forests (Querco-Fagetea), meadows (Molinio-Arrhenatheretea), dry grasslands (Festuco-Brometea), and marsh grasslands (Phragmito-Magnocaricetea). The quality of the data is discussed, such as researcher bias, preferential selection of sampling sites, spatial autocorrelation and missing values for some data elements.
