Questions: What are the syntaxonomic and synchorological patterns of the xerothermic
chasmophytic vegetation in the central part of the Mediterranean Basin?
What are the diagnostic species of the high-rank
syntaxa of Asplenietalia glandulosi,
Onosmetalia frutescentis and Centaureo dalmaticae-Campanuletalia pyramidalis?
Location: Mediterranean coastal and subcoastal areas of southern France, Italy,
Malta, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Albania and of mainland
Greece.

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: We present the results of a phytosociological investigation of segetal plant communities colonizing winter arable fields, olive groves, and vineyards in selected traditional agricultural areas of central Italy. Some of these communities own a great environmental and cultural value and are threatened by changes in agriculture. Given the lack of knowledge, this paper aims to introduce the recent diversity of traditional agriculture weed vegetation in this part of Italy by means of the collection of original data. Study area: Latium and Abruzzo regions (central Italy).
