F I G U R E 1 in Phylogeography of Solomon Islands blossom bats reflects oceanic divides and Pleistocene connections
F I G U R E 1 Study area and taxa: (a) the Solomon Islands and Bismarck archipelagos (EPSG: 4326 – WGS 84) with distributions of species M. melanops (orange), Nesonycteris woodfordi (green) and N. fardoulisi (blue), and subspecies (labelled). Bathymetric depths less than 120 m in Solomon Islands (ETOPO1, Amante & Eakins, 2009) shaded in dark grey indicate possible land bridge connections during the Last Glacial Maximum. Putative Pleistocene land bridge configurations suggested by ETOPO1 data (Amante & Eakins, 2009) are presented as grey shading for (a) the Solomon Islands archipelago, with members of landmass termed 'Greater Bukida' indicated in green; (b) the New Georgia group of islands and (c) the islands of Santa Isabel, Ngella and Guadalcanal. Putative Pleistocene land bridge configurations prepared by Mayr and Diamond (2001) are indicated by black solid outlines.

Microsatellite data from: Multiple colonizations and genetic differentiation from the mainland populations in insular populations of the perennial herb Solidago virgaurea complex (Asteraceae) on recently formed nearshore oceanic islands
<p><b>Aim: </b>Although the evolution of island endemic plants has long been investigated, the majority of such studies have focused on species with remarkable levels of morphological variation and on islands substantially far from the mainland. Except for a few examples such as the Canary Islands, endemic plants on nearshore oceanic islands have received less attention. In this study, we examined the <i>Solidago virgaurea </i>complex on the Japanese mainland Honshu and the adjacent Izu Islands to investigate the population genetic structure and dynamics in plants endemic to nearshore and recently formed oceanic islands.</p> <p><b>Location: </b>Japanese mainland Honshu and the adjacent Izu Islands</p> <p><b>Taxon: </b><i>Solidago virgaurea</i> (Asteraceae)</p> <p><b>Methods: </b>Sixteen and nine populations of <i>S. virgaurea</i> complex were sampled from the mainland and islands, respectively; phylogeographic and population genetics analyses were performed using plastid DNA and nuclear microsatellite DNA variations.</p> <p><b>Results: </b>Phylogenetically close plastid DNA haplotypes were shared between the mainland and islands, although the populations of <i>S. virgaurea</i> from different islands tended to exhibit phylogenetically distinct haplotypes. Admixture analyses based on nuclear DNA variations revealed distinct genetic structures between the mainland and island populations. Gene flow among islands is restricted but may partially offset genetic drift on each island.</p> <p><b>Main conclusions: </b>The genetic structure observed in this study may not have originated from a single dispersal event and successive expansion but rather from at least three colonization events and subsequent gene flow among island populations. Based on the nuclear DNA variations, the Izu Island populations of <i>S. virgaurea</i> are genetically distinct from the mainland ones. Repeated colonization events may have provided sufficient genetic diversity, which would generally be susceptible to founder effects and exert a driving force for evolutionary adaptation, to these oceanic island populations.</p>
