Satellite-based measurements of the normalized difference vegetation index (NDVI; an greenness and photosynthetic capacity) indicate that tundra environments are generally greening becoming more productive as climates warm in Arctic. The greening, however, varies is even negative some parts To help interpret space-based observations, International Polar Year (IPY) Greening Arctic project conducted ground-based surveys along two >1500 km transects span all five bioclimate subzones. Here we...
Accurate ground-based datasets are important for correct interpretation of remote sensing data.West-Siberian Arctic has been exposed to rapid land-cover and land-use changes during the last 50 years.Cryogenic landslides disturbing agents in region, especially central part Yamal Peninsula.Different succession stages recovery cryogenic described at example 4 model ones formed respectively 1989, middle 1970s, late 1950s or early 1960s an ancient landslide back scarp dated with radiocarbon...
Abstract Geobotanical subdivision of landcover is a baseline for many studies. The High–Low Arctic boundary considered to be fundamental natural importance. wide application different delimitation schemes in various ecological studies and climatic scenarios raises the following questions: (i) What are common criteria define High Low Arctic? (ii) Could human impact significantly change distribution criteria? (iii) Is widely accepted temperature criterion still relevant given ongoing climate...
Abstract Plant communities are coupled with abiotic factors, as species diversity and community composition both respond to influence climate soil characteristics. Interactions between vegetation factors depend on plant functional types (PFT) different growth forms will have differential responses effects site However, despite the importance of PFT for assembly ecosystem functioning, research has mainly focused vascular plants. Here, we established a set observational plots in two...
The Arctic ecosystems and their species are exposed to amplified climate warming and, in some regions, rapidly developing economic activities. This study assesses, models, maps the geographic patterns of community-level plant richness Western Siberian estimates relative impact environmental anthropogenic factors driving these patterns. With our study, we aim at contributing toward conservation efforts for diversity Arctic. Arctic, Russia. We investigated importance predictors using...
The local flora method has been used by Russian botanists for studying vast wilderness areas. strives to determine the total within a certain limited area and provides comparable data spatial comparisons between different locations temporal at same location. Complete vascular plant diversity was sampled in 240 localities with an 100 300 km 2 each throughout Arctic. These were incorporated specially developed Integrated Botanical Information System (IBIS). This database unique opportunity...
Syntaxonomic diversity of the vegetation in southern tundra subzone Tazovsky Peninsula is represented by six associations, three subassociations and variants. Four associations (Dicrano maji–Salicetum lanatae Khitun ass. nov. hoc loco, Sphagno girgensohnii–Betuletum nanae Empetro subholarctici– Eriophoretum vaginati Eriophoro leiocarpi–Caricetum rotundatae loco), (Hierochloo alpinae– Hylocomietum splendentis empetretosum subholarctici subass. typicum caricetosum chordorrhizae loco) variants...
Abstract Motivation The goal of the Russian Arctic Vegetation Archive (AVA‐RU) is to unite and harmonize data plot‐based plant species their abundance, vegetation structure environmental variables from Arctic. This database can be used assess status as a baseline document biodiversity changes in future. archive for scientific studies well inform nature protection restoration efforts. Main types contained contains 2873 open‐access geobotanical plots. include full species. Most plots...
Abstract Questions How do plant communities on zonal loamy vs. sandy soils vary across the full maritime Arctic bioclimate gradient? are of these areas related to existing vegetation units European Vegetation Classification? What main environmental factors controlling transitions along Location 1700‐km Eurasia Transect (EAT), Yamal Peninsula and Franz Josef Land (FJL), Russia. Methods The Braun‐Blanquet approach was used sample mesic plots 14 total study sites at six locations, one in each...
Abstract Vegetation properties of arctic tundra vary dramatically across its full latitudinal extent, yet few studies have quantified ecosystem gradients with field-based observations that can be related to remotely sensed proxies. Here we present data from field sampling six locations along the Eurasia Arctic Transect in northwestern Siberia. We collected on aboveground vegetation biomass, normalized difference index (NDVI), and leaf area (LAI) for both sandy loamy soil types, analyzed...
For the first time, a complete annotated list of vascular plant species is provided and local flora (LF) “Burulginsky Cape” analyzed. It richest known LF in lower reaches Indigirka River (262 subspecies, 109 genera, 41 families), including number rare northern Yakutia seven listed regional Red Book, as well taxa endemic to Arctic ×Trisetokoeleria jurtzevii Probat. ×T. taimyrica Tzvel. The similarity studied with LFs from East Siberian Chukotka provinces floristic region (lower Anabar, Lena,...
The syntaxonomic diversity of meadows and mires in the 3 sites studied within axial part Polar Urals includes 5 associations subassociations, which belong to classes phytosociological classification. 4 subassociations are described for first time. One association (Carici lachenalii–Harrimanelletum hypnoidis ass. nov.) 2 (C.l.–H.h. typicum subass. nov. C.l.–H.h. phyllodocetosum coer uleae we assigned class Salicetea herbaceae Br.-Bl. 1948.

The syntaxonomic diversity of vegetation two localities in the southern part typical tundra subzone Gydansky Peninsula includes seven associations, three subassociations and eight variants. New associations (Tanaceto bipinnati–Salicetum polaris Khitun ass. nov. hoc loco, Calliergono cordifolii–Salicetum lanatae loco), (Hierochloo alpinae–Hylocomietum splendentis asahinetosumchrysantae subass.

The syntaxonomic diversity of vegetation in the upper reaches Enga-Yu River is described. specificity study area was determined by ubiquitous occurrence ultramafic rocks, which contributed to an increase harshness habitats due high concentration heavy metals and low calcium content. Unfavorable geochemical environments caused absence several common this region species same time change ecological preferences amplitude other species. Within lower middle parts alpine belt, we distinguished...
The paper aims to describe Russian approaches inventory of vascular plants diversity in the Arctic. In study, local flora method is used. It provides comparable data for spatial comparisons between different locations. includes study species distributions within a landscape, therefore concept “partial flora” was elaborated. A complex estimate “activeness” allows assess role landscape. These theoretical concepts are applied at hardly accessible central part Gydansky Peninsula. numbers 191...
Two peaceful underground nuclear explosions conducted in the middle of 1970-s theMiddle Siberia were followed by accidental release radionuclides into atmosphere. Thecondition vegetation within impacted area was examined 2002. The study showedthat norn1alization radioactive situation and recovery damaged did not happenduring this period. Radioactive contamination resulted either total or partial elimination ofthe vegetation. Four zones according to degree disturbance distinguished....

The local flora (LF) surrounding the research station at Kytalyk Resourse Reserve was studied in detail and an annotated checklist is presented. Species composition of area compared with LF three neighboring areas lower reaches Indigirka River. These localities had differing topography, therefore their species richness varied. Research Station numbered 131 vascular plant from 66 genera 28 families. Low explained by prevalent flat homogenous lowland topography. We found new northernmost this...
