“…Our power function model has an overall predictive capacity of R 2 = 0.93 and is consistent with the R 2 -value reported for the ISAR power function model of 488 islands across the globe (Kreft et al 2008). It is also in line with the R² value reported for the Echinades islets group (R 2 = 0.84, Iliadou et al 2014b) and for some Ionian islands (R 2 = 0.89, Iliadou et al 2014a). The z-value is an important parameter that reflects the increase of species richness with increasing surface area.…”

The Ionian archipelago is the second largest Greek archipelago after the Aegean, but the factors driving plant species diversity in the Ionian islands are still barely known. We used stepwise multiple regressions to investigate the factors affecting plant species diversity in 17 Ionian islands. Generalized dissimilarity modelling was applied to examine variation in the magnitude and rate of species turnover along environmental gradients, as well as to assess the relative importance of geographical and climatic factors in explaining species turnover. The values of the residuals from the ISAR log10‐transfomed models of native and endemic taxa were used as a measure of island floristic diversity. Area was confirmed to be the most powerful single explanatory predictor of all diversity metrics. Mean annual precipitation and temperature, as well as shortest distance to the nearest island are also significant predictors of vascular plant diversity. The island of Kalamos constitutes an important plant diversity hotspot in the Ionian archipelago. The recent formation of the islands, the close proximity to the mainland source and the relatively low dispersal filtering of the Ionian archipelago has resulted in islands with a flora principally comprising common species and a low proportion of endemics. Small islands keep a key role in conservation of plant priority sites.

“…During our field investigations on the island in two sampling periods with a 25 year interval, 351 plant taxa were registered in total belonging to 84 families and 246 genera. Of the taxa recorded in total, 42.4% belong to the families Asteraceae, Poaceae, Lamiaceae, Fabaceae and Brassicaceae, which are amongst the best-adapted families to the ecological conditions of the Mediterranean area, as is confirmed by many floristic studies of Greek insular areas (amongst others Panitsa and Tzanoudakis 2001; Panitsa and Tzanoudakis 2010; Kougioumoutzis et al 2012; Iliadou et al 2014a; Iliadou et al 2014b). This is also the case when floristic composition of the two sampling periods (SA and SB) is examined separately (Table 1).…”

Lake Pamvotis is one of the Balkan "ancient" lakes, a Quaternary refugium of great environmental importance and ecological value, that is under various anthropogenic pressures. It belongs to a Natura 2000 Special Area for Conservation and Special Protection Area. Almost in the middle of the lake, there is an inhabited island - one of the two lake islands in Greece – that also attracts touristic interest. Τhe main objectives of the present study are to provide a floristic inventory of the protected island, combining data of two different sampling periods, within a 25 year interval, in order to estimate temporal beta diversity and species turnover of the island’s plant diversity. The value of the absolute and relative turnover rates of the floristic diversity of the island studied are 4.24 and 1.72, respectively and are amongst the higher rates reported for plants. The absolute difference between extinct (E) and immigrant (l) taxa is to a great extent accounted, concerning life forms, by therophytes (1.86), hemicryptophytes (1.56) and geophytes (1.04) and, for habitats, by taxa preferring agricultural and ruderal forms (2.52).
