Sažetak
Seven small islands of Kvarnero bay (Dolfin, Maman, Lukovac, Šailovac, Lisac, Galebovi otoci, Sridnjak, Sv. Marin) were included in the research. The islands of Maman, Sridnjak, Šailovac and Lukovac are situated near the island of Rab ; Lisac is south of the town of Senj, Sv. Marin lays before the town of Novi Vinodolski ; Dolfin is near the island of Pag and Galebovi otoci are south of the island of Goli. The area of islets vary from 0, 843 ha (Sv. Marin) to 25, 978 ha (Dolfin). Geologically, all of the islets are made of limestone and are part of Dinaric karst. On some islets (Maman, Sridnjak and Šailovac), the limestone is covered with a thin layer of sandy soil. The climate of the researched area is characterised by a mean annual air temperature of 15º ; C and 1150 mm of percipitation per year. Additionally, the climate on some of the islets (Lukovac, Lisac, Sv. Marin, Dolfin, Galebovi otoci) is influenced by the northeastern bora wind. For the first time, a list of complete vascular flora was made for each islet based on field observations and determination of collected herbarium material. The research was carried out during the vegetation seasons 2006-2007. The total flora of all researched islands is comprised of 200 taxa from 64 families. The most abundant families are: Fabaceae (11%), Asteraceae (8%), Poaceae (6, 5%), Liliaceae (5, 5%), Chenopodiaceae (5%). For the purpose of comparing the richness of species, c- and z- values from the power function model (Arrhenius equation) were calculated, as well as α -index of diversity. Several species- area models were tested using convex and sigmoid curve groups. Comparative frequencies of species were also calculated for all islets.
