European Vegetation Archive (EVA): an integrated database of European vegetation plots

The European Vegetation Archive (EVA) has been developed since 2012 by the IAVS Working Group European Vegetation Survey as a centralized database of European vegetation plots. It stores copies of national and regional vegetation-plot databases on a single software platform. Data storage in EVA does not affect the ongoing independent development of the contributing databases, which remain the property of the data contributors. A prototype of the database management software TURBOVEG 3 has been developed for joint management of multiple databases that use different species lists. This is facilitated by the SynBioSys Taxon Database, a system of taxon names and concepts used in the individual European databases and their matches to a unified list of European flora. TURBOVEG 3 also includes procedures for handling data requests, selections and provisions according to the approved EVA Data Property and Governance Rules. By 30 June 2015, 61 databases from all European regions have joined EVA, contributing in total 1 024 236 vegetation plots from 57 countries, 82% of them with geographical coordinates. EVA provides a unique data source for large-scale analyses of European vegetation diversity both in fundamental research and nature conservation applications. Updated information on EVA is available online at http://euroveg.org/eva-database

Contribution to the floristic knowledge of Guilleries and Collsacabra (eastern Catalonia, Spain), II

Presentem noves dades corològiques per a la flora vascular dels massissos de les Guilleries i del Collsacabra. En total, tractem 25 tàxons que podem dividir en cinc grups: 1.- nous per a les Guilleries (Peucedanum officinale L., Senecio adonidifolius Loisel., etc.); 2.- nous pel Collsacabra (Carex liparocarpos Gaudin, Seseli tortuosum L., etc.); 3.- nous per un ampli sector del nord-est català (Carex demissa Hornem., Potentilla recta L., etc.); 4.- de presència dubtosa o no retrobats per autors recents (Trifolium micranthum Viv., Carex alba Scop., etc.) 5.- que constitueixen el límit meridional de l’espècie a Catalunya (Narcissus moleroi Fern. Casas i Lamium galeobdolon (L.) L.).We report new data on the chorology of 25 vascular plants from the Guilleries and Collsacabra mountains. These taxa may be grouped into five categories: 1.- novelties for the flora of Guilleries (Peucedanum officinale L., Senecio adonidifolius Loisel., etc.); 2.- novelties for the flora of Collsacabra (Carex liparocarpos Gaudin, Seseli tortuosum L., etc.); 3.- novelties for a broader area in the NE of Catalonia (Carex demissa Hornem., Potentilla recta L., etc.); 4.- confirmation of old or doubtful citations (Trifolium micranthum Viv., Carex alba Scop., etc.); 5.- taxa found in their southernmost localities in Catalonia (Narcissus moleroi Fern. Casas and Lamium galeobdolon (L.) L.)

Se confirma la presencia de Trifolium alpestre L. en la Península Ibérica.

Trifolium alpestre es una especie eurosiberiana propia de pastizales relativamente secos y claros de bosque, que crece a menudo en estaciones abrigadas (de Bolòs & Vigo, 1984; Coombe, 1968; Saule, 2002), desde los Pirineos hasta el Cáucaso. Se trata de una especie vivaz de crecimiento marcadamente cespitoso

Macroclimate and local hydrological regime as drivers of fen vegetation patterns in Tierra del Fuego (Argentina)

In southern South America, a sharp macroclimatic gradient is found, triggered by the Pacific oceanic influence through the Andes. Mires are substantial landscape units along the gradient, where they play varying roles through the area and include varying plant communities. In this study, we analysed the relationship between vegetation and main abiotic factors in the minerotrophic mires (fens) at two different scales. We chose three fens in Isla Grande from Cordillera and Magellanic Steppe zones and their ecotone. There we characterized the distinct habitats by means of monitoring the water table fluctuations, the peat and the groundwater chemistry, and the vascular plant species composition. The main floristic patterns were revealed by means of classification and ordination of 75 vegetation plots. Thus, we classified the relevés through multivariate analyses into six plant community types, two of which found in each fen. Behind the floristic distinctiveness of each site and each community type, structural vegetation descriptors such as species richness were similar. Overall, water table variables and groundwater chemistry showed the most important environmental differences between fens. Our data point that the main environmental force driving vegetation patterns was the macroclimatic gradient, which shapes the regional floristic pools. This gradient would be also responsible for modifying the local conditions of the fen habitats, mostly in the form of broadening the hydrological conditions within the fens of the Steppe. At each fen, the hydrological regime is the main factor in the distribution of vascular plants, particularly through the varying water table depths

Primula hirsuta All. dans les Pyrénées orientales

Confirmem la presència d’aquesta espècie als Pirineus Orientals basant-nos en noves recol•leccions i observacions de camp. A més a més, presentem una revisió crítica de les citacions anteriors i dels testimonis d’herbari existents. Finalment, resumim la corologia d’aquesta espècie als Pirineus i concloem que hauria d’ésser considerada com a vulnerable (VU) a Catalunya seguint els criteris de l’UICN.Our new collections and field observations confirm the presence of this species in the Eastern Pyrenees. Moreover, we present a critical revision of the previous doubtful citations and of the extant herbarium sheets. Finally, we sum up the chorology of the species on the Pyrenean range and we conclude that the species should be considered as vulnerable (VU) in Catalonia according to criteria UICN.Nos nouvelles récoltes et données de terrain confirment la présence de cette espèce dans la partie orientale des Pyrénées, mise en doute dans quelques travaux ibériques récents. Aussi, nous présentons une révision critique des citations antérieures et des échantillons d’herbier existants.
