“…When we analysed the five modules separately, all of them displayed high rates of species spatial turnover and richness difference ( Table 2). Runemark (1971) first noticed that there might be some degree of compartmentalization in Kik; based on Lund's Botanical Museum extensive collections, he grouped together the following islands: Andros-Tinos-Mykonos, Kea-Kythnos-Serifos, Paros-Naxos and Sikinos-Folegandros. Netcarto recognized five modules that partly concur with Runemark's tentative classification.…”

“…Netcarto recognized five modules that partly concur with Runemark's tentative classification. However, Runemark (1971) stated that Serifos and Sifnos, as well as Syros and Tinos show great floristic dissimilarities with each other. In our analysis, these islands were grouped together in the same modules (in NWC and NC, respectively).…”

“…Strid (1996), based on Rechinger (1943Rechinger ( , 1950, divided Greece into 13 phytogeographical areas. Rechinger & Rechinger-Moser (1951), Runemark (1970) and Greuter (1970Greuter ( , 1971 were the first phytogeographers to address the distributional and floristic problems arising from the palaeogeographical history of the Aegean Sea.…”

Aim Although the factors shaping plant species richness patterns across the islands of the central Aegean are well known, the processes driving the assembly of these island communities remain unclear. To shed light on these processes, we identified biogeographical modules within the phytogeographical area of the Cyclades and tested for nestedness across the islands. Location The Cyclades, Greece. Methods We used a network approach to detect island biogeographical roles and modules, based on a large and detailed database of the Greek endemic plant taxa of the Cyclades, and we tested for nestedness in the island–species matrices. Results The Cyclades were significantly modular and divided into five biogeographical modules. Three of the modules were significantly nested and two displayed all four possible biogeographical roles (connectors, module hubs, network hubs, peripherals). Most of the network's taxa are classified as peripherals and widespread endemics. Main conclusions The borders of the five modules correspond remarkably well to the palaeogeographical and climatic compartmentalization of the Cyclades. The flora of the Cyclades has not yet reached the relaxation phase and the region may act as an ecogeographical filter for the distribution of several plant lineages. Naxos, Milos and Anafi play an important role for the network's connectivity, while at least five adjacent phytogeographical regions affect the distribution patterns of the endemic taxa present in the Cyclades.

“…The ecological setting of endemics needs definition, but there is little systematic ecology at all, much less adequate attention to endemic plants. Runemark (1969Runemark ( , 1971 invokes extinction by reproductive drift to explain otherwise inexplicable extinctions and vagaries of species' distributions on these islands. Has any extinction occurred?…”

The present study of Brassica cretica had two objectives. First, we compared estimates of population structure (Q st ) for seven phenotypic characters with the corresponding measures for allozyme markers (F st ) to evaluate the supposition that genetic drift is a major determinant of the evolutionary history of this species. Secondly, we compared the genetic (co)variance (G) matrices of five populations to examine whether a long history of population isolation is associated with large, consistent differences in the genetic (co)variance structure. Differences between estimates of F st and Q st were too small to be declared significant, indicating that stochastic processes have played a major role in the structuring of quantitative variation in this species. Comparison of populations using the common principal component (CPC) method rejected the hypothesis that the G matrices differed by a simple constant of proportionality: most of the variation involved principal component structure rather than the eigenvalues. However, there was strong evidence for proportionality in comparisons using the method of percentage reduction in mean-square error (MSE), at least when characters with unusually high (co)variance estimates were included in the analyses. Although the CPC and MSE methods provide different, but complementary, views of G matrix variation, we urge caution in the use of proportionality as an indicator of whether genetic drift is responsible for divergence in the G matrix.
