Abstract
The vascular flora of small offshore islets around Karpathos (Dodecanesos, Greece) has been surveyed and monitored during six consecutive years. The present study focuses on four islets that are inhabited by the ‘islet specialist’ Silene holzmannii (Caryophyllaceae), a species that has a widely scattered distribution in the Aegean where it exclusively occurs on very small islands. Repeated census of its populations, partly following controlled extirpation, reveals extreme variation in number of individuals. Sowing experiments involving various species demonstrate the low probability of successful new colonizations. Differences in the amount of apparent turnover of species as well as the occurrence of both stable micro-populations and mass-populations are discussed.
Nomenclature
