At the intersection of geological activity, climatic fluctuations, and human pressure, the Mediterranean Basin – a hotspot of biodiversity – provides an ideal setting for studying endemism, evolution, and biogeography. Here, we focused on the Roucela complex, a group of 12 taxa found primarily in the eastern Mediterranean Basin. Plastid and low-copy nuclear markers were employed to reconstruct evolutionary relationships and estimate divergence times within the Roucela complex and more specifically, Campanula erinus, using bothgenes and species tree analyses. Niche modeling, ancestral range estimation, and diversification analyses were conducted to provide further insights into patterns of endemism and diversification through time. These studies highlights the diversity and complexity of historical processes driving plant evolution in the Mediterranean Basin.
