Plant species richness, biogeographic and conservation interest of the vascular flora of the satellite islands of Sicily: patterns, driving forces an…

2013

The vascular flora has been investigated on about 60 of the approximately 100 islands and islets of the Sicilian archipelago. This paper provides detailed information on the number of exclusive, rare, or threatened vascular plants living on these islands and islets. Focusing on the 18 most-investigated islets, we evaluate the extent to which species richness, rate of endemism, number of alien plants, and number of terrestrial habitats have been influenced by 1) geographical setting, 2) geological history, 3) geo-pedological variability, 4) bioclimate, 5) number and patchiness of local plant communities, and 6) natural and human disturbance history and regime. Special attention is directed t…
