Fifteen names are given in addition to the Indexes 1987, 1990 and 1991 (Theurillat & Moravec 1990, 1993, 1994).     

Phytosociological nomenclature and typification of names of heathland syntaxa from W Europe (classCalluno-Ulicetea)

The correct names, author citations and nomenclatural types of the syntaxa names are established for the principal ranks above the association. These syntaxa areUlicion minoris Malcuit 1929,Ericion umbellatae Br.-Bl., P. Silva, Rozeira etFontes 1952,Genisto-Vaccinion Br.-Bl. 1926,Ulicetalia minoris Quantin 1935 andCalluno-Ulicetea Br.-Bl. etR. Tx. 1943     

A coenocline of the high-ranked syntaxa of ruderal vegetation

Two sets comprising 1419 and 1350 phytosociological relevés of ruderal vegetation classified into 9 and 7 orders, respectively, from an area in the Podunajská ní zina Lowland, western Slovakia were ordinated using correspondence and detrended correspondence analyses. The paper describes a coenocline of the high-ranked syntaxa contained in the data sets, and discusses some issues of the classification of the syntaxa involved.The Bidentetalia and Potentillo-Polygonetalia should be considered a special category of synanthropic vegetation as habitat moisture (flooding and waterlogging) play the controlling role in the formation of structural and dynamical patterns within these communities. The latter factor complex is responsible for the clear separation of these orders from the other syntaxa included in the ordinations. The coenocline of terrestrial ruderal vegetation units has the following sequence along the CA axis 1: Poo-Polygonetalia, Sisymbrietalia, Eragostrietalia, Onopordetalia, Agropyretalia repentis, Artemisietalia vulgaris and Glechometalia hederaceae.Various complexes of soil factors and anthropogenic disturbance are operational along the concatenation (a series of portions composing the coenocline). The factor complex includes soil compaction, trampling disturbance, nutrient status, soil texture and moisture, and solar irradiation. Step-by-step ordination and interpretation of concatenated portions of the coenocline proved to be useful in the analysis of complex data sets.Abbreviations CA = correspondence analysis - DCA = detrended correspondence analysis - PCA = principal components analysis     

The inhibitory activity of typified propolis against Enterococcus species

Propolis, a natural bee product widely used for its antimicrobial activity, was tested against isolates of Enterococcus from humans, pig-tailed macaques, isolates of refractory endodontic treatment cases, and isolates from Lactobacillus-containing food supplements. Typification of the propolis was performed by high-performance liquid chromatography (HPLC) by which prenylated compounds, cinnamic acid derivatives, and flavonoids were detected as the main constituents. Minimum inhibitory concentrations (MIC) were determined using the agar dilution method. All human and animal Enterococcus isolates demonstrated MIC values of 1600 microg/mL. Enterococcal species of human and animal origin were inhibited by propolis. Particularly, human isolates of E. faecium and E. faecalis of refractory endodontic treatment cases were susceptible to propolis of Brazilian origin.     

New syntaxa for the prodrome of Italian vegetation

The aim of this study is to provide new syntaxa for the Italian vegetation checklist. For the class Rhamno–Prunetea which includes the class Paliuretea the new alliance Rhamno saxatilis–Paliurion spinae-christi is described, that is included in the order Paliuretalia spinae-christi with a central-western Mediterranean and sub-Mediterranean distribution. Otherwise, the more thermophilous Paliurus spina-christi vegetation is included in the new suballiance named as Oleo sylvestris–Paliurenion spinae-christi within the alliance Oleo–Ceratonion of the class Quercetea ilicis. For the class Trifolio–Geranietea medii, a new alliance named Hyperico calabricae–Asphodelion macrocarpi is proposed here.
