Rising temperatures in the Arctic can affect soil organic matter (SOM) decomposition directly and indirectly, by increasing plant primary production thus allocation of plant-derived compounds into soil. Such compounds, for example root exudates or decaying fine roots, are easily available microorganisms, alter older SOM ("priming effect"). We here report on a priming experiment active layer permafrost from central Siberian Arctic, comparing responses topsoil, mineral subsoil, cryoturbated...
Abstract Soils of high latitudes store approximately one‐third the global soil carbon pool. Decomposition organic matter (SOM) is expected to increase in response warming, which most pronounced northern latitudes. It is, however, unclear if microorganisms are able utilize more stable, recalcitrant C pools, when labile pools will be depleted due increasing temperatures. Here we report on an incubation experiment with intact cores a frost‐boil tundra ecosystem at three different temperatures...
Cryoturbation (mixing of soil layers due to repeated freeze‐thaw processes) is a major forming process in arctic regions, which may contribute long‐term storage C soils northern latitudes. Our goal was determine the effect subduction organic matter by cryoturbation on microbial decomposition processes tundra soils. Buried were situated at 30–60 cm depth, between Bg and B horizons, but exhibited N content highly similar present‐day A horizons. Radiocarbon dating revealed, however, that mean...
Abstract. The Siberian forest is a tremendous repository of terrestrial organic carbon (C), which may increase owing to climate change, potential increases in ecosystem productivity and hence C sequestration. Phosphorus (P) availability could limit the sequestration potential, but tree roots mine soil deep access mineral P. Improved understanding quantification processes controlling P surface layers ecosystems are thus required. objectives present study were (1) evaluate status horizons from...
Earth hummocks constitute the most common surface structures of Arctic regions. In hummock tundra ecosystems, small mounds earth alternate with depressions, so-called interhummock areas. This study aimed at elucidating how differences in microtopography and associated variations abiotic biotic factors control biogeochemical cycles soils. We assessed N pools transformation rates areas southern subzone along a soil-moisture gradient typical Taymyr Peninsula, Siberia, Russia. On regional scale,...
Abstract. Climate change is particularly strong in northern Eurasia and substantial ecological changes are expected this extensive region. The reshaping migration northwards of bioclimatic zones may offer opportunities for agricultural development western central Siberia. However, the vegetation models currently employed projections still do not consider soil fertility, spite being highly critical plant growth. In present study, we surveyed phosphorus (P) status south-west Siberia where...
Managing soil biodiversity by reduced or no tillage is an increasingly popular approach. Soil mycobiome in Siberian agroecosystems has been scarcely studied; little known about its changes due to tillage. We studied Chernozem under natural steppe vegetation and cropped for wheat conventional a long-term field trial West Siberia, Russia, using ITS2 rDNA gene marker (Illumina MiSeq sequencing). Half of the identified OTUs were Ascomycota with 82% total number sequence reads showing, like other...
Abstract Southwest Siberia encompasses the forest-steppe and sub-taiga climatic zones has historically been utilized for agriculture. Coinciding with predicted changes in climate region is pressure of agricultural development; however, a characterization soil water carbon dynamics lacking. We assessed current properties organic turnover forests grasslands two sites that span forest steppe bioclimatic zones. Soil evaporation was 0.62 ± 0.17 mm d −1 (mean standard error) 0.45 0.08 site....
The onshore and offshore clastic deposits of the Argive Basin Argolic Gulf, respectively, in Peloponnese, Greece, form a Late Neogene–Quaternary half-graben that connects with Aegean Sea. sequence, comprised chaotically intercalated cohesive granular deposits, is angular unconformity bedrock Triassic–Upper Cretaceous strongly-weathered, highly-fractured karstic limestones thrusted against Paleogene flysch deposits. While surface geology well-known, subsurface remains both poorly mapped...
Managing soil biodiversity using reduced tillage is a popular approach, yet bacteriobiomes in the agroecosystems of Siberia has been scarcely studied, especially as they are related to tillage. We studied Chernozem under natural steppe vegetation and cropped for wheat conventional or no long-term field trial Novosibirsk region, Russia, by sequence diversity V3/V4 region 16S rRNA genes. Actinobacteria, Acidobacteria, Proteobacteria summarily accounted 80% total number sequences, with...
AbstractSince 1995, soil-ecological field courses across climatic zones in West Siberia have been organized by scientists from Russia and Germany to meet growing demands for better land use practices. They are focused on virgin landscapes soils undisturbed anthropogenic influences facilitate the learning processes excluding concealing changes artifacts. The visited range taiga near Tomsk tundra Altai mountains desert conditions Mongolian border. This article describes main features of...
Microeukaryotes are vital for maintaining soil quality and ecosystem functioning, however, their communities less studied than bacterial fungal ones, especially by high throughput sequencing techniques. Alveolates important members of microbial communities, being consumers and/or prey other microorganisms. We alveolate diversity in under the undisturbed steppe (US) cropped wheat using two tillage practices (conventional, CT, no-till, NT) amplifying ITS2 marker with ITS3_KYO2/ITS4 primers...
The aim of our study is to assess changes in soil macroinvertebrate biodiversity when conventional tillage (CT) replaced by no-tillage (NT) agroecosystems the southern part West Siberian forest steppe. research was conducted Novosibirsk region at end May 2017, 2018, and June 2018. agricultural plots with CT NT were located close each other on identical soils, a distance about 200 m from nearest shelterbelts. technology has been applied experimental plot since 2007. Sampling invertebrates two...
