No full textFirst record of the steppic relict Astragalus exscapus L. subsp. exscapus in the Apennines (Abruzzo, Italy), and biogeographic implications
No full textAstragalus exscapus L. subsp. exscapus (Fabaceae) is a rare and declining perennial herb with a very fragmented distribution range. It is interpreted as a relict of the glacial steppe flora. In Italy, it was known until now only from the Alpine “dry valleys”, namely from Val d’Aosta and Val Venosta/Vinschgau. We report on the discovery of a population on the slopes of the Fucino basin in the Central Apennines (Abruzzo, Italy). The finding significantly expands the known species range (the site is >600 km away from the nearest known populations), suggesting that during Pleistocene steppic phases it had a wide distribution across Europe. A. exscapus adds to a number of other steppic relicts found in the Fucino basin, highlighting that some inner valleys of the Central Apennines, featuring a relatively continental climate, perform as “interglacial refugia” for the steppe flora. Further research is needed to ascertain the species’ local distribution and abundance, and to clarify its vicariance history; however, the finding underlines the need to re-evaluate priorities in landscape management, as in the Apennines dry grasslands are often given low values compared to forests and are frequently destroyed by afforestation practices with non-native conifers
The map of the vegetation series of Italy.
No full textWe present the methodology developed for mapping the vegetation series of Italy (at scale 1:250.000) in the frame of the project "Completion of Basic Naturalistic Knowledge", funded by the Italian Ministry of the Environment. A hierarchical land classification is combined with expert knowledge of vegetation dynamics and phytosociological field data. The Map of the Vegetation Series is an essential tool for ecological planning and land management

No full textcommentary by Carrion & Fernandez (Journal of Biogeography, 2009, 36, 2202-2203) compared Holocene pollen records with models of potential natural vegetation (PNV) proposed in the phytosociological literature and concluded that the predicted PNV resulted from anthropogenic disturbance. However, the authors misinterpreted PNV, leading to two serious flaws in their assumptions: (1) PNV is not defined as a pre-anthropic or climax plant community; and (2) PNV is not a concept restricted to the phytosociological method. Therefore we criticize the conclusions expressed in the commentary, and we stress the need for an interdisciplinary approach based on multi-temporal and multi-spatial scales to achieve a modern framework for the study of plant communitie
