| Résumé : |
18 associations of Dryas octopetala-dominated communities, which belong to 3 classes and 4 alliances, were observed in the European Arctic and in north-western Siberia. Syntaxonomical differentiation is linked with the ecogeographical and floristical division of the Arctic: alliance Kobresio-Dryadion of Carici rupestris–Kobresietea bellardii has its main distribution in European arctic and typical tundra and in the oroarctic belt of mountains, whilst the area of alliance Dryado octopetalae–Caricion arctisibiricae lies in the southern and typical tundra and oroarctic belt on the north of Pechora Plain, in theYugorskii Peninsula, Pay-Khoy Mts. and Polar Ural. Dryas octopetala-dominated communities lacking characteristic species of Carici rupestris–Kobresietea bellardii have been related to the alliance Cassiopo-Salicion herbaceae (Salicetea herbaceae) and alliance Loiseleurio-Diapension (Loseleurio-Vaccinietea). In the latter a suballiance Salicenion nummulariae has been proposed comprising xero-, achyonophytic communities on sandy and gravelly substrata in the southern and typical tundra of the north-east of European Russia. A synoptical table is provided. |
