  • Distribution of the Solidago virgaurea complex in the Japanese Archipelago

    Rapid ecological diversification of the Eurasian goldenrod complex

    The Solidago virgaurea complex shows remarkable morphological and ecological diversity in Japan. Phylogeographic analysis suggested the multiple expansions from the Eurasian continent into the archipelago via land bridges, followed by lineage diversification within the island chain. Its genetic structure corresponds to the geography, but interestingly there is no concordance between genetic and ecotypic boundaries. Sakaguchi […] More

    Eastern expansions of itinerant olive (Olea europaea)

    Mapping a new direction for the origin and distribution of olive (Olea europaea), Mousavi et al. measure genetic diversity levels and population genetic structure of a representative set of Iranian ecotypes and varieties of olives screened by chloroplast and nuclear markers. The results of this analysis are coupled with archaeo-botanical and historical data, tracing a […] More

    Population genetic patterns in an endangered island perennial

    Oceanic islands are of particular importance for the conservation of global diversity. Rare island plants with small population sizes and unique genetic patterns resulting from prolonged evolutionary isolation are usually extremely fragile. Therefore, research dedicated to conservation of these plants should consider threat factors, population structure and genetic diversity to enable the development of scientifically […] More

  • Collection locations, temperature data and population structure of Miscanthus in eastern Russia.

    A genome-wide association study of wild Miscanthus in the Russian Far East

    Miscanthus is a genus of C4 perennial East Asian grasses that is emerging as a leading bioenergy crop. Clark et al. collected germplasm of M. sacchariflorus and M. sinensis in the Russian Far East, at the northern extent of the range of these two species. Geographic distributions suggest greater winter hardiness in M. sacchariflorus than […] More

  • Anagenetic speciation in Acer okamotoanum

    Anagenetic speciation in Acer okamotoanum

    Anagenesis (also known as phyletic speciation), in which initial founder populations simply diverge through time without a branching event, is an important process of speciation in endemic species of oceanic islands. Takayama et al. investigate the genetic consequences in Acer okamotoanum (Sapindaceae), an anagenetically derived species endemic to Ullung Island, South Korea. No geographical genetic […] More

    Free—open access paper: Isolated history of the coastal plant Lathyrus japonicus (Leguminosae) in Lake Biwa, an ancient freshwater lake

    Lathyrus japonicus commonly inhabits seashores. However it also grows near the shores of an inland lake (Lake Biwa, an ancient japanese freshwater lake) where it is assumed to have been isolated for a long time. The impact of this long-term isolation on phylogeographic and population structures is described. This reveals low genetic diversity due to […] More

  • Phylogeography of Caribbean pines

    Phylogeography of Caribbean pines

    Phylogeography of Caribbean pines Four species of Pinus subsection Australes occur in the Caribbean Basin, and Jardón-Barbolla et al.  analyse their phylogeny to assess possible colonization events from Central America. They find that independent colonizations gave rise to the plastid lineages of P. caribaea var. bahamensis and of P. caribaea var. caribaea. The expansion time […] More
