The first complete and updated checklist of vascular plants Asian Russia is compiled. It based on “Checklist Flora Russia: Vascular Plants” (Baikov 2012) but incorporates numerous floristic, taxonomic nomenclatural novelties. territorial scope the constituted by three federal districts (Ural, Siberian Far Eastern). Sverdlovsk Oblast Chelyabinsk are included in for time. Native, alien, naturalized, casual aliens frequently cultivated (not found outside cultivation) taxa included. monotypic...
The Altai Mountains of Central and North Asia are biologically rich comprise a wide range ecosystems phytogeographical regions. According to the latest checklist, total 321 endemic vascular plant species, including 217 104 subendemic taxa, have been recognized in Mountain Country (AMC). In this study, we conducted species risk assessment, distribution evaluation conservation gap analysis for flora AMC. status was assessed at global level using ConR package. As result, 197 were evaluated as...

<p>Scanning electron microscopy (SEM) was used to perform a comparative study for four representatives of the subfamily <em>Ceratopteridoideae</em> (J. Sm.) R.M. Tryon from East Asia: <em>Ceratopteris thalictroides</em> Brongn., <em>C. pteridoides</em> (Hook.) Hieron., <em>Acrostichum aureum</em> Linn., and <em>A.</em> <em>speciosum </em>Willd. The analysis external morphology revealed strong difference between...
Spores of Cystopteridaceae from northern Asia were examined using scanning electron microscopy. To evaluate the utility spore morphology in taxonomy each genus, we spores 14 species: seven species Gymnocarpium and Cystopteris. Among these are 12 occurring two other regions for comparative studies. The study focused particularly on perispore characters size. all monolete, bean-shaped, with a range size 26–56 × 18–37 μm Cystopteris 25–48 16–34 Gymnocarpium. is morphologically diverse within...
Методом сканирующей электронной микроскопии (СЭМ) проведено сравнительное исследование ультраструктуры поверхности спор шести образцов Pityrogrammacalomelanos (L.) Link (Pteridoideae, Pteridaceae), собранных в разных участках ареала: Южном Китае (о-в Хайнань), Непале, Гондурасе, Эквадоре, на Ямайке. Установлено, что для образцов, ареала, характерны постоянство признаков скульптуры и низкая вариабельность размеров. Споры тетраэдрические, трехлучевые, с ровными тонкими лучами лезуры;...
A comparative study of spores seven pecies: Taenitis blechnoides (Willd.) Sw., T. hookeri (C. Chr.) Holttum, pinnata (J. Sm.) Syngramma alismifolia (Presl) J. Sm., S. lobbiana (Hook.) quinata Carruth., and Austrogramme boerlageana (Alderw.) Hennipman from South-Eastern Asia was performed using the method scanning electronic microscopy (SEM). Spores all examined species are trilete, tetrahedral or tetrahedral-globose. very similar to each other in shape ornamentation. Ornamentation both sides...

(E. sylvaticum), sergijevskianum C. N. Page et Gureeva palustre), lofotense Lubienski sylvaticum). Скульптурные элементы из кремнезема различаются по форме, размерам расположению на ребрах в...
Ultrastructure of epidermal surface stem internodes 4 species and 2 interspecific hybrids subgenus Hippochaete (Milde) Baker (Equisetum L., Equisetaceae) were studied using scanning electron microscopy: Equisetum hyemale E. ramosissimum Desf., scirpoides Michx., variegatum Schleich. ex F. Weber et D. Mohr, E.× moorei Newman, × trachyodon (A. Braun) W. J. Koch. Epidermal ornamentation in is fundamentally different from that Equisetum. The most visible elements the surface, specific for...

The global climate change and significantly increased anthropogenic pressure on the Arctic Subarctic regions require modern ecosystem monitoring understanding of past environmental changes. Vegetation history is reflected by pollen spectra recorded in peat deposits, investigation which one main methods research long-term climatic In order to reconstruct vegetation fire today’s south tundra lower reaches Taz river, we carried out palynological exploration underlying lake sediments covering...
A comparative study of spores two species Vaginularia (Vittarioideae, Pteridaceae) from South-Eastern – paradoxa (Fée) Mett. ex Miq. and V. trichoidea Fée was performed by the method scanning electronic microscopy (SEM). Spores are tetrahedral, trilete; they very similar to each other in smooth surface relatively narrow laesura arms. Differences between shape proximal position (triangular with narrowly-rounded corners concave sides triangular broadly-rounded slightly trichoidea), length arms...
A comparative study of spores four species Haplopteris C. Presl, H. amboinensis (Fée) X.C. Zhang, forrestiana (Ching) E.H. Crane, linearifolia and mediosora (Hayata) from China was performed using the method scanning electronic microscopy (SEM). Spores are bilateral monolete ellipsoidal or ellipsoidal, but slightly narrowed in middle. Perispore thin, easily breakable, smooth; exospore smooth, its surface is finely granulate undulate (as seen at higher magnification). have largest...
The ultrastructure of the spore surface Onychium ipii Ching (Pteridoideae, Pteridaceae) was investigated by using scanning electron microscopy. Spores are trilete, tetrahedral, with hemispherical distal side and convex proximal one. Equatorial diameter 42.4–48.1 μm, polar axis 35.7–40.6 μm. Distal sides separated an equatorial flange, which protrudes on 4.3–4.8 μm all around spore. Tubercles different size form interrupt "laesura lips" situated both laesura arms. Proximal three stright...

Ecological and cenotic features of the old-growth forests Siberian pine – Pinus sibirica Du Tour situated in mountain-glacial basin Aktru North-Chuya glaciation center Russian Altai at altitudes 2160–2300 m a.s.l. were examined for first time. These can be defined as virgin ones since they have never been subjected by direct human-caused disturbances throughout their existence. This makes them a valuable pattern undisturbed Altai. The age primary generation P. forming base tree layer these...
