[CBNPMP-Géographique] Pyrénées centralesRésumé : Here we report new data concerning 58 rare plants, mainly recorded in the Aigüestortes i Estany de Sant Maurici National Park or in neighbouring areas (from Vall d’Aran to Andorra). For each taxon, we discuss the phytogeographic interest of the new locations given, according to the present knowledge of the Pyrenean flora. Festuca alpina Suter subsp. riverae Chas, Kerguélen & Plonka and Trisetum spicatum (L.) K. Richt. subsp. ovatipan-iculatum Hultén ex Jonsell become novelties for the Catalan flora, and we confirm the presence of Lathyrus bauhinii Genty and Trisetum baregense Laffite & Miégeville. In other cases, the new data improve the distributional knowledge of rare plants in the above-mentioned area or in Catalonia.

Location : Europe. Methods : A data set of vegetation-plot records was compiled to include various bog types over most of the European continent. An unsupervised classification (beta-flexible linkage method, Sørensen distance measure) and detrended correspondence analysis (DCA) ordination were applied. Formal definitions of syntaxa based on species presence and covers, and respecting the results of the unsupervised classification, were developed and included in a classification expert system. Results : The Oxycocco-Sphagnetea class, its two orders (Sphagno-Ericetalia tetralicis and Sphagnetalia medii) and seven compositionally distinct alliances were formally defined. In addition to the syntaxa included in EuroVegChecklist, three new alliances were distinguished: Rubo chamaemori-Dicranion elongati (subarctic polygon and palsa mires); Erico mackaianae-Sphagnion papillosi (blanket bogs of the northwestern Iberian Peninsula); and Sphagno baltici-Trichophorion cespitosi (boreal bog lawns). The latter alliance is newly described in this article. Conclusions : This first pan-European formalized classification of European bog vegetation partially followed the system presented in EuroVegChecklist, but suggested three additional alliances. One covers palsa and polygon mires, one covers Iberian bogs with endemics and one fills the syntaxonomical gap for lawn microhabitats in boreal bogs. A classification expert system has been developed, which allows assignment of vegetation plots to the types described.

Ellenberg-type indicator values are expert-based rankings of plant species according to their ecological optima on main environmental gradients. Here we extend the indicator-value system proposed by Heinz Ellenberg and co-authors for Central Europe by incorporating other systems of Ellenberg-type indicator values (i.e., those using scales compatible with Ellenberg values) developed for other European regions. Our aim is to create a harmonized data set of Ellenberg-type indicator values applicable at the European scale.
Methods
We collected European data sets of indicator values for vascular plants and selected 13 data sets that used the nine-, ten- or twelve-degree scales defined by Ellenberg for light, temperature, moisture, reaction, nutrients and salinity. We compared these values with the original Ellenberg values and used those that showed consistent trends in regression slope and coefficient of determination. We calculated the average value for each combination of species and indicator values from these data sets. Based on species’ co-occurrences in European vegetation plots, we also calculated new values for species that were not assigned an indicator value.
Results
We provide a new data set of Ellenberg-type indicator values for 8908 European vascular plant species (8168 for light, 7400 for temperature, 8030 for moisture, 7282 for reaction, 7193 for nutrients, and 7507 for salinity), of which 398 species have been newly assigned to at least one indicator value.
Conclusions
The newly introduced indicator values are compatible with the original Ellenberg values. They can be used for large-scale studies of the European flora and vegetation or for gap-filling in regional data sets. The European indicator values and the original and taxonomically harmonized regional data sets of Ellenberg-type indicator values are available in the Supporting Information and the Zenodo repository.Identifiant : DOI : 10.1111/jvs.13168 Permalink : https://biblio.cbnpmp.fr/index.php?lvl=notice_display&id=155707

Titre : Glacial relict Sphagnum fuscum at the Pyrenean rear-edge: Genetically depauperate and highly differentiated populations Type de document : Imprimé Auteurs : Joan Cuscó-Borràs ; Núria Garcia-Jacas ; Jordi López-Pujol ; Eulàlia Pladevall-Izard ; Aaron Pérez-Haase Année de publication : 2026 Article en page(s) : 1-15 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Changement climatique
[CBNPMP-Géographique] PyrénéesMots-clés : Sphagnum fuscum Résumé : Cold-adapted species often persist at their rear-edge in isolated refugia, where they are especially vulnerable to climate change. These populations frequently harbour unique genetic lineages and local adaptations, making them critical for biodiversity conservation. However, fine-scale intraspecific genetic and ecological data are rarely integrated into conservation planning. For the locally threatened peat moss Sphagnum fuscum at its southern rear-edge in the Pyrenees, we aimed to reveal its regional demographic status and genetic structure in order to inform conservation strategies. We genotyped 104 shoots from seven Pyrenean populations using 16 nuclear microsatellite markers. Genetic patterns were analysed using AMOVA, STRUCTURE, PCoA, MSN, and UPGMA and Complete Linkage dendrograms based on Bruvo's distance. We also estimated population sizes and surveyed sporophyte production in the field. Pyrenean populations exhibited extremely low within-population diversity and complete genetic distinctiveness among them. Pyrenean genotypes shared a private allele distinctive from the populations of Canada and Norway. Sporophyte production was widespread, although many populations were monoclonal, probably consistent with regional monoicy. Pyrenean populations likely constitute an evolutionary significant unit, which should be prioritised in conservation planning. Our results provide a basis for designing a genetic rescue by promoting gene flow among these isolated populations.
