- CircumMed+Euro pine forest database: an electronic archive for Mediterranean and European forestsPublication . Bonari, Gianmaria; Knollova, Ilona; Vickova, Pavla; Xystrakis, Fotios; Çoban, Suleyman; Saglam, Coskum; Didukh, Yakiv P.; Hennekens, Stephan M.; Acosta, Alicia T.R.; Angiolini, Claudia; Bergmeier, Erwin; Bertacchi, Andrea; Costa, José Carlos; Farfarillo, Emanuele; Gigante, Daniela; Guarino, Riccardo; Landi, Marco; Neto, Carlos S.; Pesaresi, Simone; Rosati, Leonardo; Selvi, Federico; Sotiriou, Alex; Stinca, Adriano; Turcato, Claudia; Tzonev, Rossen; Viciani, Daniele; Chytry, MilanLarge thematic databases of vegetation-plots are increasingly needed for vegetation studies and biodiversity research. In this paper, we present the CircumMed+Euro Pine Forest Database (GIVD ID: EU-00-026), which in September 2018 encompassed 5590 records from pine-dominated vegetation plots (relevés) and associated vegetation types from 23 countries of temperate Europe, Eastern Mediterranean and North Africa. These vegetation plots were collected through a detailed literature search for plots not included in the European Vegetation Archive (EVA). The database includes plots from 192 bibliographic references and unpublished vegetation plots by different authors. All vegetation plots are georeferenced, and coordinates are available with different accuracy as reported by the authors. The database is managed by the Vegetation Science Group, Department of Botany and Zoology of the Masaryk University in Brno (Czech Republic). It is registered in the Global Index of Vegetation-Plot Databases (GIVD) with the code EU-00-026 and is accessible through the European Vegetation Archive (EVA) or by asking the Custodian. The CircumMed+Euro Pine Forest Database is an important resource for conducting different types of broad-scale studies in the fields of vegetation classification, plant invasion ecology, macroecology and biological conservation
- Classification of the Mediterranean lowland to submontane pine forest vegetationPublication . Bonari, Gianmaria; Fernández-González, Federico; Çoban, Süleyman; Monteiro-Henriques, Tiago; Bergmeier, Erwin; Didukh, Yakiv P.; Xystrakis, Fotios; Angiolini, Claudia; Chytrý, K.; Acosta, Alicia T.R.; Agrillo, E.; Costa, José Carlos; Danihelka, J.; Hennekens, S.M.; Kavgacı, A.; Knollová, I.; Neto, Carlos; Sağlam, C.; Škvorc, Z.; Tichý, L.; Chytrý, M.Aim: Vegetation types of Mediterranean thermophilous pine forests dominated by Pinus brutia, Pinus halepensis, Pinus pinaster and Pinus pinea were studied in various areas. However, a comprehensive formal vegetation classification of these forests based on a detailed data analysis has never been developed. Our aim is to provide the first broad-scale classification of these pine forests based on a large data set of vegetation plots. Location: Southern Europe, North Africa, Levant, Anatolia, Crimea and the Caucasus. Methods: We prepared a data set of European and Mediterranean pine forest vegetation plots. We selected 7,277 plots dominated by the cold-sensitive Mediterranean pine species Pinus brutia, Pinus halepensis, Pinus pinaster and Pinus pinea. We classified these plots using TWINSPAN, interpreted the ecologically and biogeographically homogeneous TWINSPAN clusters as alliances, and developed an expert system for automatic vegetation classification at the class, order and alliance levels. Results: We described Pinetea halepensis as a new class for the Mediterranean lowland to submontane pine forests, included in the existing Pinetalia halepensis order, and distinguished 12 alliances of native thermophilous pine forests, including four newly described and three informal groups merging supposedly native stands and old-established plantations. The main gradients in species composition reflect elevational vegetation belts and the west–east, and partly north–south, biogeographical differences. Both temperature and precipitation seasonality co-vary with these gradients. Conclusions: We provide the first formal classification at the order and alliance levels for all the Mediterranean thermophilous pine forests based on vegetation-plot data. This classification includes traditional syntaxa, which have been critically revised, and a new class and four new alliances. We also outline a methodological workflow that might be useful for other vegetation classification syntheses. The expert system, which is jointly based on pine dominance and species composition, is a tool for applying this classification in research and nature conservation survey, monitoring and management
