[ZG] EuropeMots-clés : carte de répartition habitat EUNIS Résumé : "This projects aims at parameterising the grassland units of the revised EUNIS habitat classification across Europe. Using the comprehensive plot dataset from the European Vegetation Archive (EVA), all grassland habitats (habitat group E) of Europe (including the coastal grey dunes, habitat subgroup B1.4) are formally defined with a unanimous floristic definition (with a new expert system approach, implemented in JUICE). For the 53 distinguished habitat types of grasslands sensu lato, for the first time lists of diagnostic, constant and dominant species are provided, based on statistical evaluation of the whole European dataset. Further, each of this habitats is presented with a distribution map based on the plots contained in EVA (ca. 250,000 georeferenced plots). Further cross-walks to the old EUNIS classification and the system used in the new European Red List of habitats are provided. All in all, the report represents the first consistent and data-based characterisation of grassland vegetation types on a level that roughly corresponds to phytosociological alliances (e.g. "E1.2a - Semi-dry perennial calcareous grassland" = Brometalia erecti; "E1.2b = Continental dry steppe" = Festucetalia valesiacae)."

ISBN/ISSN/EAN : 978-3-936055-03-0 Langues : Allemand (ger) Résumé : "The project "Die Pflanzengesellschaften Mecklenburg-Vorpommerns und ihre Gefährdung" (The plant communities of Mecklenburg-Vorpommern and their vulnerability) is published as a two-volume series consisting of a table volume (2001) and a text volume (2004). Based on a huge vegetation-plot database and a consistent and well-documented methodology, the complete vegetation of this federal state in NE Germany was phytociolociologally classified de novo. The result are 34 phytosociological classes, 12 subclasses, 70 orders, 6 suborders, 125 alliances and 284 associations. This text volume contains detailed descriptions, nomenclatural revisions, diagnostic species and conservation assessments of all syntaxa of Mecklenburg-Vorpommern. The Introductory section provides detailed insights into the natural history of the study region as well as the methodology of the project. The concluding Conservation section summarizes the outcomes of the unique conservation assessment methodology applied in the project. An Introduction and summary for English-speaking readers (M. Isermann & J. Dengler; pp. 16–21 of the text volume 2004) makes most of the content of both volumes accessible to persons not comprehending German."

Eisenberg, Auteur ; Florian Jansen, Auteur ; I. Koska, Auteur ; S. Löbel, Auteur ; M. Manthey, Auteur ; Jens Päzolt, Auteur ; A. Spangenberg, Auteur ; Tiemo Timmermann, Auteur ; H. Wollert, Auteur Année de publication : 2003 Article en page(s) : pp. 587-631 Langues : Anglais (eng) Mots-clés : syntaxon phytosociologie Résumé : "This paper contains the original diagnoses of new syntaxa, typifications of existing names of syntaxa, and other decisions of nomenclatural relevance which have proved to be necessary within the project ‘Plant communities of Mecklenburg-Vorpommern and their vulnerability’. The underlying syntaxonomic concept is documented in Dengler & Berg (2002). In Berg et al. (2001b, 2003) we have discussed in detail the syntaxonomic system as it applies to the federal state of Mecklenburg-Vorpommern in NE Germany.
In the introductory sections we deal with some methodological questions and explain the mode of presentation adopted in the special section. We follow strictly the rules of the International Code of Phytosociological Nomenclature (ICPN), but have recognised six aspects in which the present version of the ICPN is unclear or contradictory. For these cases we suggest reasonable solutions that are followed in the special section.
The special section of our work will be published in two parts. The present paper deals with nine phytosociological classes belonging to the herbaceous terrestrial vegetation (Polygono-Poetea annuae, Sisymbrietea, Stellarietea mediae, Calluno-Ulicetea, Koelerio-Corynephoretea, Festuco-Brometea, Molinio-Arrhenatheretea, Trifolio-Geranietea, Artemisietea vulgaris). Altogether 17 new syntaxa are validly published (including validations of previously used names and changes in rank). One name of a syntaxon is corrected due to a taxonomic error and 151 further syntaxa are typified. Nomenclatural questions are discussed if appropriate and the reasons given when applications concerning nomina ambigua, conservanda, inversa or mutata are proposed.
The most important syntaxonomic novelties are the following: Subdivision of the Sisymbrietea into several orders, of which the Sisymbrietalia and the Conyzo canadensis-Brometalia tectorum ord. nov. occur in Central Europe – Subdivision of the Stellarietea mediae into the Aperetalia spicae-venti, the Dicranello staphylinae-Stellarietalia mediae ord. nov. and the Papaveretalia rhoeadis ord. nov. – Subdivision of the Koelerio-Corynephoretea into the two subclasses Koelerio-Corynephorenea subcl. nov. and Sedo-Scleranthenea subcl. nov. – Establishment of an alliance Filipendulo vulgaris-Helictotrichion pratensis all. nov. which contains floristically impoverished semi-dry grasslands in the southern Baltic area – Subdivision of the Molinio-Arrhenatheretea into the two subclasses Arrhena-therenea subcl. nov. and Molinio-Juncenea subcl. nov. – Subdivision of the Trifolio-Geranietea into the two subclasses Melampyro-Holcenea subcl. nov. und Trifolio-Geranienea subcl. nov. (containing the Origanetalia vulgaris s. str. and the Antherico-Geranietalia sanguinei ord. nov.) – Subdivision of the Artemisietea vulgaris into the four subclasses Epilobienea angustifolii, Lamio albi-Urticenea dioicae subcl. nov., Agropyrenea intermedio-repentis subcl. nov. (containing the Rubo caesii-Calamagrostietalia epigeji ord. nov. and the Agropyretalia intermedio-repentis) and Artemisienea vulgaris."

[Thèmes] Typologie des végétationsMots-clés : syntaxon phytosociologie Résumé : "Within the project ‘Plant communities of Mecklenburg- Vorpommern and their vulnerability’, a current synopsis of all vegetation types (excluding onelayered cryptogam vegetation) from this federal state in NE Germany has been worked out and published in a two-volume monograph (BERG et al. 2001, 2004a). An extensive data base of vegetation relev.s and a consistent methodology provided the basis for the classification. On the one hand, this classification differs in various features from well-known syntaxonomic concepts. On the other hand, the careful application of the Code of Phytosociological Nomenclature has led on several occasions to the conclusion that certain syntaxa lack valid names or that correct names can only be determined after a typification. Consequently all new descriptions, typifications and other nomenclatural decisions which are relevant to our project are being published in separate papers. Most are included in a two-part publication of which this contribution represents the second one.
In an introductory section, we describe some of the special features of our project, discuss the possible contribution of this regional study to the general system of plant communities, and point out the significance of the ICPN. We then briefly explain the nomenclatural evaluations and abbreviations used in the special section, as a supplement to the corresponding paragraphs in Part I (DENGLER et al. 2003). The main substance of the paper deals with the nomenclatural revision of 18 vegetation classes belonging predominantly to the aquatic, semiaquatic or woody vegetation. The following classes are dealt with: Lemnetea, Ruppietea maritimae, Potamogetonetea, Littorelletea, Thero-Salicornietea strictae, Montio-Cardaminetea, Oxycocco-Sphagnetea, Parvo- Caricetea, Phragmito-Magno-Caricetea, Juncetea maritimi, Cakiletea maritimae, Salicetea purpureae, Vaccinio uliginosi-Pinetea, Molinio-Betuletea pubescentis, Alnetea glutinosae, Vaccinio-Piceetea, Quercetea robori-petraeae and Carpino-Fagetea. Within these classes we describe 15 new syntaxa. One illegitimate name is replaced by a nomen novum, and in four cases we correct syntaxon names based on taxomomic errors. Finally, lecto- and neotypes of a further 134 syntaxa are designated. In the context of the syntaxa treated, we discuss some nomenclatural problems involved and give reasons for the scheduled proposals to the Nomenclature Commission for nomina ambigua, conservanda, inversa and mutata.
The majority of the presented syntaxonomic modifications concern the vegetation of wetlands: In addition to the floristic differentiation of the syntaxa, special emphasis has been put on their clear ecological definition, particularly in terms of nutrient supply, hydrology and alkalinity of their habitats. In the classification of forest and shrub vegetation from hydromorphic sites, we have therefore placed emphasis on the ground vegetation instead of the few predominantly euryecious tree species. Compared to other classifications, the most important differences are as follows: The drawing up of a central order Sphagno fallacis-Eriophoretalia vaginati ord. nov. beside the Sphagno-Ericetalia and the Sphagnetalia magellanici within the Oxycocco-Sphagnetea – Subdivision of the Parvo-Caricetea (mesotraphent mire vegetation) into an acidophilous and a basiphilous subclass (Sphagno fallacis-Caricenea canescentis subcl. nov. and Drepanoclado revolventis- Caricenea diandrae subcl. nov. respectively) – Subdivision of the Phragmito-Magno-Caricetea into the four orders Phragmitetalia australis, Nasturtio officinalis- Glycerietalia fluitantis, Scrophulario umbrosae- Caricetalia paniculatae ord. nov. and Calystegietalia sepium – Subdivision of the Molinio-Betuletea pubescentis (woody vegetation of mesotrophic wetlands) into the orders Salici pentandrae-Betuletalia pubescentis ord. nov. and Calamagrostio canescentis- Salicetalia cinereae – Subdivision of the Alnetea glutinosae (woody vegetation of eutrophic wetlands) into the orders Cardamino amarae- Alnetalia glutinosae ord. nov., Alnetalia glutinosae and Alno-Fraxinetalia excelsioris."

We identify shortcomings in available data that need to be addressed through sampling under‐represented geographic regions, providing better incentives for data collection and sharing, developing user‐friendly database exchange standards, as well as tools to analyse and remove confounding effects of sampling biases. The increased availability of data sets conferred by registration in GIVD offers significant opportunities for large‐scale studies in community ecology, macroecology and global change research."
