Evolution and biogeography of the flora of the Socotra archipelago (Yemen)

The Socotra Archipelago, an isolated continental fragment in the Western Indian Ocean, exhibits remarkable floristic diversity and endemism shaped by at least 18 million years of isolation. Despite its significance as a unique biogeographical system—often likened to the Galapagos of the Indian Ocean—it remains understudied. This research reveals that Socotra's flora has undergone significant local adaptations and radiations, providing key insights into island biogeography. By analyzing origins, affinities, disjunctions, and environmental influences, the study elucidates the evolutionary processes contributing to its distinct biodiversity. The findings highlight Socotra as a critical case study for understanding long-term isolation and ecological specialization in island ecosystems.
