Mid- and late-Holocene vegetation and fire history at Biviere di Gela, a coastal lake in southern Sicily, Italy

2009

The vegetation and fire history of few coastal sites has been investigated in the Mediterranean region so far. We present the first paleoecological reconstruction from coastal Sicily, the largest island in the Mediterranean Sea. We analysed pollen and charcoal in the sediments of Biviere di Gela, a lake (lagoon) on the south coast of Sicily. Our data suggest that the area became afforested after a marine transgression at ca. 7200 cal b.p. (5250 b.c.). Build-up of forest and shrublands took ca. 200–300 years, mainly with the deciduous trees Quercus, Ostrya and Fraxinus. Juniperus expanded ca. 6900 cal b.p. (4950 b.c.), but declined again 6600 cal b.p. (4650 b.c.). Afterwards, evergreen trees…

Aspetti di vegetazione a leccio e carpino nero nei Monti Sicani (Sicilia centro-occidentale)

2009

Viene studiata con metodo fitosociologico una formazione forestale a leccio e caratterizzata dalla presenza di Ostrya carpinifolia. La fitocenosi studiata, presente in alcune forre umide e ombreggiate dei Monti Sicani occidentali, viene provvisoriamente riferita all’Ostryo carpinifoliae-Quercetum ilicis Lapraz 1975. Rispetto al tipo dell’associazione, la formazione forestale in esame si differenzia per l’elevato grado di copertura di O. carpinifolia e per la costante presenza di K. silaifolia e P. mascula subsp. russoi.

Early screening of new accumulating versus non-accumulating tree species for the phytomanagement of marginal lands

2019

International audience; The use of fast-growing trees producing a high quantity of biomass can bring significant practical and economic benefits to the reclamation of marginal lands. The present study aims to identify new shrub/tree species to offer a wider range of shrubs/trees useful for phytomanagement practices. We implemented three experimental sites in France of 1 ha each (Thann, Carrières-sous-Poissy and Leforest) contaminated by different potentially toxic elements (PTE) with a total of 38 different tree species. After two years of growth, the element concentrations in stem and leaf biomasses, tree survival rate and growth of plants were assessed. Although the three sites had elevat…
