dynamically linked to the deciduous oak woods, which are widespread within the upper-colline, submontane and lower montane belts (800-1400
m) of the Tyrrhenian side of the northern Sicily and in the Sicani mountains. In the study area B. rupestre grasslands were mainly found in colluvial
plains or drainage lines where relatively deep and mesic soils occur. In this paper 42 phytosociological relevés were performed and statistically

Aims: The majority of research on the diversity-productivity relationship has utilized aboveground plant biomass as a measure of overall ecosystem productivity and investigated successions with species-poor early stages. During this study we modelled patterns of plant diversity and carbon pools along a succession from pasture abandonment to submediterranean Quercus cerris woodland and investigated ecosystem productivity using biomass and soil carbon. Study area: The hilly-mountainous area of Tolfa in Central Italy.

Humans have increasingly been affecting fire regimes through changes in the amount and distribution of ignition energy and fuel load. Within the context of global change, recent studies have shown that changes in demography and land use account for far more variability in shaping fire regimes than climatic variations. The objectives of this study are to analyze temporal trends in fire ignitions in selected land use/land cover (LULC) classes in Sardinia (Italy) over the years 2000–2015, and to assess the role of demographic dynamics from 1971 to 2011 over such changes.
