| Abstract |
The Adriatic flora is an excellent example of the geographical speciation in the marine algae. This is the richest and the most autonome flora of the Mediterranean region. The types of its endemic algae are panadriatic (limited on the Adriatic basin), insulary (Central Adriatic islands), and coastal (Dalmation channels). The most important disjunctions of its relict algae are Adriatic-Atlantic, and Kvarner Gulf-Mediterrannean Sea. The ecological isolation of the Northern A`driatic by means of a variable salinity, the continental bora-winds, a colder water, and periodic winter glaciations in the littoral of Kvarner, is very intense; and therefore there are a lot of boreal algae. The floristic sectors of the Adriatic are Pelagic, Dalmation, Quarneric, and Venetian. The most important examples of the geographical speciation in the Adratic algae: endemic and monotypic family Yadranellaceae; an Adriatic exclave of the genus Fucus with the endemic F. virsoides; a Quarneric exclave of the Lithophyllum tortuosum s.I. with a psychrophilous ecotype (L. ercegovioii); and some endemic species and ecotypesof the gen Cystosera. |
