A revision of the higher syntaxa of meadows of the Russian Far East has been made on the basis of results of ecological, phytocoenotic and chorological analyses of associations and higher units published by M. Achty­amov (1985, 1987а, б, 1995, 2000) and G. Dymina (1980, 1985). Conceptual basis for existing syn­taxo­nomic system of the meadows and leading diagnostic features of syntaxa have been reviewed. Authors propose to include all diverse Daurian-Manchurian meadows into two different classes. Hygro-mesic meadow communities of bogged flood-plane habitats with excessive moisture supported by subterranean waters have been included in the class Cala­magros­tietea langsdorffii Mirkin in Achtyamov et al. 1985. Diagnostic species are Anemonidium dichotomum, Calamagrostis langsdorffii, Caltha membran acea, Carex appendiculata, C. schmidtii, Filipendula pal­mata, Fimbripetalum radians, Galium davuricum, Iris laevigata. Lathyrus pilosus, Lysimachia davurica, Sanguisorba parviflora, Saussurea amurensis, Spiraea salicifolia, Stachys aspera, Nomenclature type of the class is the order Calamagrostietalia langsdorffii Achtyamov et al. 1985. Drought-tolerant xero-mesic meadows of zonal sites with fluctuating moisture regime supported by monsoon climate have been included in the class Arundinello anomalae—Agros­tie­tea trinii cl. nova hoc loco. Nomenclature type of the class is the order Artemisietalia mandshuricae Achtya­mov et al. 1985. Diagnostic species are: ­Aco­nogonon divaricatum, Adenophora pereskiifolia, A. ver­ticillata, Agrostis trinii, Artemisia desertorum, A. integrifolia, A. stenophylla, Arundinella anomala, Aster tataricus, Campanula cephalotes, Carex diplasio­carpa, Dianthus chinensis, Eupatorium lindleyanum, Galium verum, Gentiana scabra, Geranium vlassowia­num, Hemero­callis minor, Iris ensata, Lathyrus quin­quener­vius, Lupinaster pentaphyllus, Patrinia sca­biosi­folia, Poten­til­la fragarioides, Ptarmica acu­mi­nata, Ranunculus japonicus, Sedum aizoon, Serratula manshurica, Tha­lictrum amurense, Trommsdorfia cilia­ta, Vicia amoena, V. pseudorobus. The ranges of both classes are concen­trated in the Manchurian floristic province of Northern Asia, in regions with obvious Pacific and Sub-Pacific climatic regimes. Their western geographical limits run near the Yablonovy mountain ridge in the Eastern part of Baikal region. Westward, the Arundinello ano­malae—Agrostietea trinii and Calamagrostietea langs­dorffii are replaced by Euro­pean-Siberian meadows of the Molinio—Arrhe­na­theretea.

A new species of scincid lizard allied to Plestiodon japonicus (Peters, 1864) was described as P. finitimus sp. nov., fromthe eastern part of Honshu and Hokkaido, Japan. A previous DNA study reported the taxonomic status of the easternJapanese populations of Plestiodon as an undescribed species on the basis of their collective genetic distinctness from aparapatric congener P. japonicus sensu strict from the western part of mainland Japan. We present the diagnostic featuresof P. finitimus compared to P. japonicus and P. latiscutatus Hallowell, 1861, the other parapatric species occurring in theIzu Peninsula and Izu Islands of central Japan, on the basis of morphological characteristics and DNA barcode patterns.Both P. finitimus and P. japonicus have a small postnasal and large anterior loreal that contacts the supralabials. In contrast,the Izu Peninsular populations of P. latiscutatus, which had no known diagnostic features relative to the other two species,usually have a large postnasal and small anterior loreal, with the latter separated from the supralabials by the former, ormay otherwise lack a postnasal. In most populations of P. finitimus, the right and left prefrontals are usually isolated fromeach other, whereas they exhibit medial contact in most populations of P. japonicus. Although all the above characters arevariable both within and between populations, 60–90% of the specimens from each locality on mainland Japan werecorrectly identified using a combination of these characters. Based on these characters, the Russian Far East populationof Plestiodon was also identified as P. finitimus. The interspecific sequence differences in the standard DNA barcoderegion (a 658 base pair fragment of the cytochrome c oxidase subunit I gene of mitochondrial DNA) were distinct, andeach of the three species was exclusively clustered in a neighbor-joining tree. The limited hybridization among the threespecies indicated by previous studies suggests that DNA barcodes could provide a reliable key for their correctidentification. The implications for the biogeography and speciation of the three parapatric lizard species are briefly discussed.

Our goal is to analyze the known geographical ranges and diagnostic features of two potentially invasive Asian buprestid species: the quarantine apple tree pest, Agrilus mali Matsumura, and the poplar pest A. fleischeri Obenberger. Based on the examination of museum collections and literature sources, we compiled comprehensive databases of records of the exact collecting sites for both species and generated detailed maps of their ranges. There are 51 documented localities for A. mali in the Russian Far East and East Siberia, Mongolia, China, and the Korean peninsula, and there are 53 documented localities for A. fleischeri in the Far East and Siberia, Kazakhstan, Mongolia, China, and Japan. No evidence of the presence of A. mali in Japan was found. Outbreak sites of A. mali in Xinjiang in the 2000s most likely represent the newly forming invasion areas; their proximity to the wild apple stands in the Kazakh part of the Tien Shan is a direct threat to Kazakhstan and adjacent countries. Sites damaged by A. fleischeri in Liaoning are situated within its native range; the outbreaks were likely triggered by the switch from indigenous to introduced poplars. This situation is similar to the early stages of emerald ash borer (Agrilus planipennis Fairmaire) invasion.

Abstract In the south of Russian Far East Amorpha fruticosa (Fabaceae Lindl.) is used as ornamental plant. It actively blooms and fruits here and successfully spreads by suckers, rarely by seeds. There are another ways of Amorpha fruticosa application in Primorsky Krai – as melliferous and technical plant for reclamation of disturbed lands and formation of protective field belts. These activities requires a great amount of quality seeds and, in turn, investigation of Amorpha fruticosa seed propagation. The study of the morphological characteristics of fruits from 12 different places in the Primorsky Krai showed that the linear characteristics of the fruits have minor differences but length of racemes and seed germination vary greatly. The longest racemes are detected in the city of Bolshoy Kamen (17.8 cm), the shortest ones – in Nekruglovo settlement (12.7 cm). The largest fruit number has racemes from Partizansk city (152). The weight of 100 fruits varies from 1.16 g (Kraskino settlement) to 0.94 g (city of Bolshoy Kamen). Highest germination capacity is observed in plants at Lake Soldatskoe (91%), the smallest in plants from Strugovka settlement and the city of Bolshoy Kamen (43%). Absence of germination of seeds from Vadimovka settlement is probably caused by pest – American seed beetle, Acanthoscelides pallidipennis.

Subject. The article addresses the tax liabilities of taxpayers registered in the subjects of the Far Eastern Federal District, which should be paid to the consolidated budget of the Russian Federation, as well as the factors of the said debt growth. Objectives. Our aim is to assess the level of tax debt of regions of the Russian Far East and identify the correlation between the factors and the amount of tax debt. Methods. The study rests on methods of analysis, generalization, grouping, systematization, and the correlation and regression analysis. Results. We analyzed the level of tax debt for the entire Far Eastern Federal District and by region, identified factors affecting the growth of tax debt therein. The paper assesses the structure of tax debt by type of taxes and activity of debtors. The unveiled factors may help control changes in the size of tax debt in the Russian Far East and develop effective measures to improve the debt collection. Conclusions. The study shows that there is an increase in the tax debt in the regions of the Russian Far East, in the VAT in particular. The factor analysis revealed that the volume of sales of wholesale enterprises, investment in fixed capital, the consumer price index have the largest impact on the amount of tax debt.

The paper summarizes information on chromosome numbers (CNs) of the Grass species (Poaceae) in the flora of Russian Federation, obtained on the original material, most part - from the Russian Far East (RFE). In some species the CNs are known in Russia or in the world only from RFE, in some – from one locality or few, or from one subregion of RFE. The grass species in RFE often occur in mountain regions and near seacoasts; some species are endemics, some were studied near the limits of their geographical distribution areas. The diversity of CNs, the special features of the CNs distribution in some grass groups are discussed. The alien species are abundant in RFE, and their CNs are also involved in the study. For karyologically polymorphous species further studies are needed.
