Radula Résumé : "The current state of the taxonomy of Rubus ser. Discolores in Czech Republic is summarized. Since 1995, when the group was studied in the Flora of the Czech Republic, 6 new species have been recognized, some of which are also known from adjacent areas. They are described in the present study: R. austroslovacus, R. flos-amygdalae, R. guttiferus, R. parthenocissus, R. pericrispatus and R. portae-moravicae. The first 5 belong to the group of triploid species close to R. montanus and R. grabowskii, whilst R. portae-moravicae is related to R. praecox. Two additional species, originally recognized under provisional names, were identical to species described earlier: R. perperus and R. phyllostachys; the latter is also found in Slovakia. At present, 17 indigenous species, one naturalized alien (R. armeniacus) and one rare garden escape (R. ulmifolius [R. inermis]) of the ser. Discolores are known to occur in the Czech Republic. Distribution data and a key for the identification of all the species are presented. " Type de publication : périodique Référence biblio : Travnicek B., Zazvorka J., 2005 - Taxonomy of Rubus ser.

Titre : Czech National Phytosociological Database : Basic statistics of the available vegetation-plot data Type de document : Livre Auteurs : Milan Chytrý, Auteur ; Marie Rafajová, Auteur Année de publication : 2003 Article en page(s) : pp. 1-15 Langues : Anglais Mots-clés : bioinformatique Czech Republic plant community phytosociologie relevé végétation survey Résumé : "The vegetation relevés stored electronically in the Czech National Phytosociological Database arereviewed. The database was established in 1996, with the central database located in theDepartment of Botany, Masaryk University, Brno (www.sci.muni.cz/botany/database.htm). On 15November 2002 this central database contained 54,310 relevés from the Czech Republic, collectedby 332 authors between 1922–2002. Ca. 54% of the relevés were taken from published papers ormonographs, 21% from theses and the rest from various unpublished reports and field-books. Theserelevés include 1,259,008 records of individual plant species. Territorial coverage of the country bythe reléves is irregular as the areas with attractive natural or semi-natural vegetation are moreintensively sampled, with gaps in coverage of less attractive or poorly accessible areas. Mostrelevésareofbroad-leaveddeciduousforests(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, preferentialselection of sampling sites, spatial autocorrelation and missing values for some data elements" Type de publication : périodique Référence biblio : Chytrý M., Rafajová M., 2003 - Czech National Phytosociological Database : Basic statistics of the available vegetation-plot data.
