Disturbance regimes are changing in forests across the world response to global climate change. Despite profound impacts of disturbances on ecosystem services and biodiversity, assessments at scale remain scarce. Here, we analyzed natural boreal temperate forest ecosystems for period 2001–2014, aiming 1) quantify their within‐ between‐biome variation 2) compare sensitivity biomes. We studied 103 unmanaged landscapes with a total land area 28.2 × 10 6 ha, distributed five continents. A...
Reliable quantitative vegetation reconstructions for Europe during the Holocene are crucial to improving our understanding of landscape dynamics, making it possible assess past effects environmental variables and land-use change on ecosystems biodiversity, mitigating their in future. We present here most spatially extensive temporally continuous pollen-based plant cover (at a spatial resolution 1° × 1°) over (last 11.7 ka BP) using ‘Regional Estimates VEgetation Abundance from Large Sites’...
Abstract. Sedimentary charcoal records are widely used to reconstruct regional changes in fire regimes through time the geological past. Existing global compilations not geographically comprehensive and do provide consistent metadata for all sites. Furthermore, age models provided these harmonised many based on older calibrations of radiocarbon ages. These issues limit use existing research into past regimes. Here, we present an expanded database records, accompanied by new recalibration...
The length of the pollen deposition period covered by an individual moss sample is a matter discussion. Here we evaluate (1) how many years are contained in samples, (2) which factors (i.e. type, geographical location and thickness sample) affect content, (3) whether time span deposited related to type. 20 samples adjacent traps was estimated using accumulation method. investigated usually contain from two five years. depends on cushion and, therefore, recommend estimating over has been...
Abstract Slash-and-burn (SAB) was a widespread agricultural practice across large parts of the boreal region until early 20th century. Despite its paramount importance in procurement food and particularly supporting frontier populations settlers during colonization Eurasian zone, analyses spatial temporal patterns use SAB at annual sub-annual scales are currently missing. We present first such analysis climatic social controls practices remote northern Ural mountains from 1880 to 1894....
Abstract At the end of nineteenth century, northern territories Russian Plain and western piedmont Northern Ural Mountains were under various land-use systems, including slash-and-burn (SAB) agriculture. Using archival materials for years 1880–1910 as data sources, we analyse location extent SAB agriculture, it timing, its impact on landscapes at turn twentieth centuries, present a review historical ethnographic literature. The study area is in Mountains, between Kama Pechora rivers dark...
The first results of modern pollen investigations from western slop Ural Mountains presented. 33 samples have been collected in June 2016 four dominant forest types (Sphagnum, true moss, tall fern and herbs sections) Pechora-Ilych state nature biosphere reserve (Komi republic, Russia). detail record surrounding vegetation was performed at every sampling point. Pollen assemblages are mostly dominated by tree (Betula type, Pinus haploxylon type Picea). records will be statistically analyzed...
Fires – one of the most important factors in catastrophic transformation natural forest cover. Destroying whole ecosystems, fires, at same time, start long-term succession processes. The study causes fires makes a significant contribution to understanding structural and functional organization dynamics modern forests. article examines impact availability territory landscape-topographical features on distribution size burnt areas formed last 150 years, foothill area Pechora-Ilych Nature...
Analysis of solar forcing climate on long time scales has shown that it is necessaryto take into consideration the influence long-term cyclicity, such as 200 and 2300–2400-year cycles, climate. Even in relatively warm last 10,000 years, atendency to cooling at deep minima cyclicity observed. Alongwith this, a manifests itself not only an external factordue irradiance variations atmosphere-ocean system, but alsoas stimulator internal processes climatic which, turn, can lead toabrupt change....

This research is dedicated to creating a data transformation and unification layer between number of medical systems (which are essentially lab equipment such as CT, MRI, X-rays scanners so on) centralized management system called PACS (picture archiving communication system).

Cryobanks use plant cryocollections for long-term preservation of crops which cannot be preserved in seed collections. These are vegetatively propagated crops, accessions species form either a small amount seeds, or recalcitrant seeds. Shoot tips (apexes) vitro plants used cryopreservation most berry therefore maintenance collections is very important. The VIR collection includes 150 Rubus L. species, 85 them raspberry cultivars, 59 were bred Russia. cultivars reflect wide ecogeographic...
High latitudes experience more evident climate warming compared to lower latitudes. The impact on the dynamics of individual species can be a complex blending contrasting forces and effects.
