ABSTRACT Maintaining the stability of ecosystems is critical for supporting essential ecosystem services over time. However, our understanding contribution diverse biotic and abiotic factors to this in wetlands remains limited. Here, we combined data from a field vegetation survey 725 herbaceous wetland sites China with remote sensing information Enhanced Vegetation Index (EVI) 2010 2020 explore temporal primary productivity. We found that plant species richness directly contributed on...
Increasing drought globally is a severe threat to fragile desert wetland ecosystem. It of significance study the effects drying on microbial regulation soil carbon (C) in desert. In this study, we examined impacts biomass, community (bacteria, fungi) and activity [basal respiration, metabolic quotient (qCO2)]. Relationships properties with biotic factors [litter, organic (SOC), total nitrogen (TN), phosphorus (TP)], abiotic (soil moisture, pH clay content) biological processes (basal qCO2)...
Inland wetlands have declined dramatically in the past century due to land drainage, agricultural intensification and soil saline-alkalization China. Soil seed banks can be an important component of ecological restoration farmed if seeds aquatic species survive cultivation. To explore response bank farming accompanied environmental stress, we compared structure composition between natural sedge meadows adjacent soybean paddy fields under two water levels (moist flooded) salinity treatments...
Soil enzyme activities play a pivotal role in ecosystem processes, such as organic carbon decomposition or nitrogen and phosphorus mineralization. Thus, measurements can provide insights into the rates of ecosystem-level processes peatlands. Hummock-hollow microtopography is common feature boreal peatlands, but its influence on soil activity not well understood. We investigated effects hummock-hollow three hydrolases (β-1,4-glucosidase (βG), 4-N-acetylglucosaminidase (NAG), acid phosphatase...
To evaluate the diurnal and seasonal variations in soil respiration (Rs) understand controlling factors, we measured carbon dioxide (CO2) fluxes their environmental variables using a LI-6400 CO2 flux system at temperate Leymus chinensis meadow steppe western Songnen Plain of China growing season (May–October) 2011 2012. The patterns could be expressed as single peak curves, reaching to maximum 11:00–15:00 falling minimum 21:00–23:00 (or before dawn). time-window between 7:00 9:00 used...
Frozen soils are mixtures of ice and solid grains. Since the mechanical properties dry granular completely different, behaviour ice-soil mixture is highly dependent on content. In this paper, a 3D model based distinct element method (DEM) introduced used for evaluating resistance frozen soil. DEM model, two groups elements representing soil particles ice. The modelling by has been widely treated in literature. However, few researches available regarding ice, no simulations have published...
Vast tracts of the wettest agricultural fields have been abandoned worldwide, hence knowledge their restoration potential is becoming important. Soil seed banks can be important components ecological restoration, particularly if seeds key structural dominants survive periods cultivation. In Changbai Mountain, China, we compared and standing vegetation between natural sedge meadows adjacent paddy under drained flooded conditions. The tussock-forming Carex schmidtii dominated plant communities...
Abstract The main purpose of this study is to assess if wetland restoration associated with a directional shift in soil element concentration toward the original prefarming status peatlands northeastern China. concentrations 55 elements and related environmental factors including organic matter content, electrical conductivity, pH were investigated natural, restored, farmed wetlands Xingkai Lake Watershed All but four varied by type (natural, wetlands), 41 increased from natural restored...
Wetlands have degraded dramatically in recent decades due to wetland drainage, agricultural reclamation, and soil salinization China. Soil seed banks, as a way of natural regeneration, can efficiently restore the aboveground vegetation if seeds survive after farming. To explore response bank farming consequent environmental changes, we compared structure composition banks between Carex-dominated Phragmites-dominated wetlands their adjacent farmed fields Songnen Plain, We found that responses...
Quantifying the temporal and spatial patterns of temperature sensitivity (Q10) soil respiration (Rs) as well its controlling factors is critical to reveal response ecological processes global warming improve carbon budget estimations at a regional scale. The seasonal annual variations in Rs were assessed during two growing seasons 2011 2012 four different vegetation sites meadow steppe Songnen Plain, China. Q10 values across all exhibited significant with minimum value (1.81–2.34) occurring...
In order to study the diurnal variation of soil CO2 efflux from temperate meadow steppes in Northeast China, and determine best time for observation, a field experiment was conducted with LI-6400 flux system under five typical plant communities (Suaeda glauca (Sg), Chloris virgata (Cv), Puccinellia distans (Pd), Leymus chinensis (Lc) Phragmites australis (Pa)) an alkali-spot land (As) at steppe western Songnen Plain. The results showed that exhibited single peak curve growing season. Diurnal...

The correlations among major soil properties at a global scale are essential for explaining the convergence of ecological processes in terrestrial ecosystems but have never been assessed. In this study, database was analyzed to determine whether were consistent and how such varied continents land use types. Across entire dataset, electrical conductivity soils increased significantly with increasing pH; additionally, total nitrogen cation exchange capacity organic carbon content, while...
