We collected and processed relevés of thermophilous deciduous forests of Southeastern Europe classified into the order Quercetalia pubescentis. Following numerical analyses we established they can be classified into eight groups. Thus we evaluated the current findings that sprang from empirical studies and proposed several new (syn)taxonomic solutions. The paper presents all alliances occurring in the region that reflect the phytogeographical position and site conditions, their distribution and diagnostic species calculated with the fidelity index.

We collected relevés of weed vegetation in the northwestern part of the Balkan Peninsula and studied their species structure and diversity. It was determined that the most important environmental variables that affect the species composition are phytogeographical position and crop, and less so the year and season of the relevé and altitude. We also investigated the changes in ß diversity along all the listed gradients and the changes in species composition and ecological conditions relative to time. ß diversity is high in cereals and during the summer, but declines with altitude.
