(Calypogeiaceae, Marchantiophyta) in Pacific Asia: Updates from Molecular Revision with Particular Attention to the Genus in North Indochina.

is a genus in Pacific Asia that is difficult to classify taxonomically. These difficulties arise from (1) considering the presence of oil bodies as anatomical characters for taxonomic differentiation, (2) the wide occurrence of sibling, semicryptic and geographical vicariant taxa and (3) the inevitable need to organize new datasets for molecular genetic revision of the genus. The present study uses an integrative approach, including molecular genetic, morphological, chorological and ecological methods, to understand the taxonomy of the genus in Amphi-Pacific Asia.

Undiscovered Biodiversity of the European Moss Flora: (Aongstroemiaceae), a New Genus and Species from SW Portugal.

A new genus is described to accommodate , a novel species resolved in the family Aongstroemiaceae, from the Monchiquense district in SW Portugal. Characterized by its small size, erect spreading to subsecund non-sheathing leaves, plane bistratose leaf margins, and rhizoidal gemmae with slightly protruberant cells, it differs from all other European Dicranellaceae in the uniquely patterned distal peristome segments with backward-pointing papillae resembling hooked barbs. The species appears to be endemic to the sub-Mediterranean bioclimatic zone, in wooded biomes where humidity remains relatively high throughout the year.

Taxonomic Composition of Subser. (Iridaceae) Inferred from Chloroplast DNA and Morphological Analyses.

The species of subser. are herbaceous perennials found mainly in southwestern and central China and also in the Eastern Himalayas. To date, six species have been recognized in this group.

The implication of leaf anatomical structure for the selective breeding of lilacs.

The cultivars of the common lilac (Syringa vulgaris) grown in the south of the Russian Far East are not always winter-hardy and are often damaged by fungal diseases due to a very humid climate. A promising trend in the selective breeding of lilacs in Russia is the creation of new breeding material based on the gene pool of the broadleaf lilac (S. oblata) and its hybrids in order to introduce valuable adaptive traits into cultivars.

Edible Far Eastern Ferns as a Dietary Source of Long-Chain Polyunsaturated Fatty Acids.

Young fronds of ferns are consumed as a vegetable in many countries. The aim of this study was to analyze three fern species that are available for sale in the Russian Far East as dietary sources in terms of fatty acids that are important for human physiology: arachidonic acid (20:4n-6, ARA), eicosapentaenoic acid (20:5n-3, EPA) and other valuable long-chain polyunsaturated fatty acids. The content of ARA and EPA was 5.

Integrating continental mainland and islands in temperate East Asia: liverworts and hornworts of the Korean Peninsula.

The liverwort and hornwort flora of the Korean Peninsula possesses some unique traits arising from the geographic position of the Peninsula, where the mainland flora meets insular flora. This flora is still not exhaustively studied, due not only to political reasons, but also because much less attention has been paid than to adjacent lands by hepaticologists. A checklist presented is based on a study of ca.

Revision of Gymnomitriaceae (Marchantiophyta) in the Korean Peninsula.

This paper provides a revision of and in the Korean Peninsula based on a study of the collections housed in the herbaria of Jeonbuk National University (JNU) and the Botanical Garden-Institute in Vladivostok (VBGI). In total, 12 species were recorded (six in and seven in ), including four taxa whose identity was not confirmed with the available materials and suspected to be recorded wrongly. Each confirmed species is annotated by morphological descriptions based on available Korean material, data on ecology, distribution, specimens examined as well as illustrations.

Liverwort flora of Ayan - a gained link between subarctic and hemiboreal floras in West Okhotiya (Pacific Russia).

The liverwort flora of Ayan was first investigated one hundred and fifty years after the first exploration of vascular plants. A number of factors has determined the relatively high taxonomic diversity of liverworts in this hemiarctic flora of small-sized area: 118 species and one subspecies were revealed. These data are new not only for the studied area, but also for the huge land adjacent to the western coast of the Sea of Okhotsk.

Temperature and pH define the realised niche space of arbuscular mycorrhizal fungi.

The arbuscular mycorrhizal (AM) fungi are a globally distributed group of soil organisms that play critical roles in ecosystem function. However, the ecological niches of individual AM fungal taxa are poorly understood. We collected > 300 soil samples from natural ecosystems worldwide and modelled the realised niches of AM fungal virtual taxa (VT; approximately species-level phylogroups).

Merger of (Betulaceae) from northern Japan with northeast Asian based on ploidy level.

It has been controversial whether , a dwarf birch distributed in Hokkaido of northern Japan, is an endemic species or a synonym of broadly distributed in northeast Asia. The endemic hypothesis is based on the idea that is diploid while is tetraploid and that they are separated based on the ploidy level; however, no chromosome data have actually been published before. Resolving the taxonomic problem is crucial also in judging the conservation priority of in a global perspective.

Genetic structure of a widespread alpine shrub Rhododendron aureum (Ericaceae) across East Asia.

The vast territory of East Asia, including southwestern Beringia, is considered to have been almost ice free during the Pleistocene. Cold-resistant flora may have persisted in this region expanding or contracting its range during the climate cooling. Only a few plant genera have been studied with a sampling area across their entire geographic range in East Asia; therefore, the understanding of the biogeographic history of alpine flora in this region remains limited.

A database of weed plants in the European part of Russia.

Background: Weeds are plants that, although not specially cultivated, grow and often adapt to growing in arable lands. They form an ecological variant of flora, as a historically-formed set of species growing on cultivated soils. For the rational use of the chemical and biological crop protection products and to produce safe and high-quality food, up-to-date data on the floristic diversity of weeds and the patterns of its geographical change are required.

S.L. (Marchantiophyta): The Complex of Sibling Species and Hybrids.

was found to be a formed by several strongly genetically different species. The taxonomic diversity in the group is the possible result of radiation in early stages; then, these taxa likely survived for a long time in similar environmental conditions, which resulted in stasis. Presently, the existing taxa are similar one to another and may be morphologically distinguished with difficulties.
