    Taxonomy and conservation in Higher Plants and Bryophytes in the Mediterranean Area
    Proceedings of the 2nd International Congress “Speciation and Taxonomy”, May 16th-18th 2014, Cefalù-Castelbuono (Italy)

    ABSTRACT
    The Mediterranean Region is among the areas of the world richest in wild and cultivated taxa. Extinctions in the Mediterranean area are bound to have occurred in historical times but they are not documented. The probable and documented cases of plant extinction in specific areas within the Mediterranean are equivalent to 0.25% of total species-by-area records. Species with a large range are more prone to local population size fluctuations and eventual extinction than species with a reduced population. Small islands floras are more prone to extinction than those on large islands and on the mainland. Reliability of our data on Mediterranean plant extinctions is poor. New emphasis on floristic research is needed to boost our deficient knowledge of the Mediterranean flora. A closer collaboration between scholars and amateurs can increase floristic knowledge and also help unravel taxonomic problems.

    Vascular flora evolution in the major Mediterranean islands

    ABSTRACT
    Characteristics of Mediterranean island floras are analyzed with stress on endemic units. On these bases the main relationships between the major Mediterranean areas and the inland territories with the strongest floristic affinities are analyzed. Finally the role of aliens in Mediterranean island floras and threats are discussed.

    Vascular flora evolution in the Soqotra Archipelago (Indian Ocean)

    ABSTRACT
    The main floristic and vegetational features of the Soqotra Archipelago are outlined. The theories of vicariance and dispersal are commented with the support of examples suggesting the idea that both are complementary in the establishment and evolution of the flora of Soqotra. Finally the relation of alien vs natural elements of the flora is analyzed.
