Abstract Similar land-use types usually have similar soil properties, and, most likely, microbial communities. Here, we assessed whether or chemical properties are the primary drivers of community composition, and how changes in one part ecosystem affect another. We applied Ion Torrent sequencing to bacterial fungal communities five different (vegetation) Loess Plateau China. found that overall trend quality was natural forest > plantation bare land. Dominant phyla consisted...
The biogeographical relationships between far-separated populations, in particular, those the mainland and islands, remain unclear for widespread species eastern Asia where current distribution of plants was greatly influenced by Quaternary climate. Deciduous Oriental oak (Quercus variabilis) is one most widely distributed Asia. In this study, leaf material 528 Q. variabilis trees from 50 populations across whole (Mainland China, Korea Peninsular as well Japan, Zhoushan Taiwan Islands)...
Abstract The semi‐arid region of the Loess Plateau in China is characterized by its fragile ecosystems. Soil erosion and water shortage are major factors influencing ecology hydrology vegetation this area. For proper management watershed ecosystems, quantification use types needed. We used Granier‐type thermal dissipation probes a black locust ( Robinia pseudoacacia ) plantation upscaled stand transpiration from individual measurements stem sap flow. Stand during growing seasons 2008–2010...
1 To increase understanding of the water table's influence on both fine-root growth and whole-plant tree species in arid semi-arid regions, we exposed Populus alba L. cuttings to contrasting soil conditions via various table gradients. 2 One-year-old rooted were grown individually pots containing sandy a greenhouse for 90 days four water-table depth treatments: constant at 45 cm from surface, 30 cm, 15 fluctuating depths between cm. Growth responses, biomass partitioning, structure...
Asian dust events transport the airborne bacteria in Chinese desert regions as well mineral particles and influence downwind area varying biological ecosystems climate changes. However, bacterial dynamics were rarely investigated Gobi area, where are highly frequent. In this study, air samplings sequentially performed at a 2-m high above ground sampling site located (Tsogt-Ovoo of desert; Mongolia 44.2304°N, 105.1700°E). During event days, cells increased to more than tenfold concentrations....
In this study we examined the role of nitrogen-fixing tree, Robinia pseudoacacia (black locust), in ectomycorrhizal (ECM) formation and ECM community Pinus thunbergii (Japanese black pine) seedlings. Two 200 m(2) experimental plots were established at border between a Japanese pine- locust-dominated area coastal forest. The fungal pine seedlings was by PCR-RFLP sequence analysis. We analyzed relationship formation, community, growth, nutrient status environmental conditions using Mantel test...
Abstract In this study, we aimed to clarify spatial variations in xylem sap flow, and determine the impacts of these on stand‐scale transpiration ( E ) estimates. We examined circumferential radial flow velocity F d measured at several directions depths tree trunks black locust Robinia pseudoacacia native oak Quercus liaotungensis ), both which have ring‐porous wood anatomy, forest stands Loess Plateau, China. evaluated estimates using a simple scaling exercise. found significant outermost...
Abstract Mycorrhizal fungi have considerable effects on soil carbon (C) storage, as they control the decomposition of organic matter (SOM), by modifying amount nitrogen (N) available for free‐living microbes. Through their access to N, ectomycorrhizal (ECM) compete with microbes; this competition is thought slow down SOM decomposition. However, arbuscular mycorrhizal (AM) cannot decompose SOM, and therefore must wait N first be processed It unclear what form ECM microbes for, or which...
Black locust (Robinia pseudoacacia) is a major reforestation species in the semiarid region Loess Plateau of China. There has been increasing concern about sustainability plantations because their possible high water-use. This study was, accordingly, undertaken to quantify stand-scale water use middle-aged black plantation region. The thermal dissipation probe method was applied 27 trees measure sap flux densities an experimental plot during growing season 2008. monoculture stand basal area...
Rapid responses of microbial biomass and community composition following a precipitation event have been reported for soil bacteria fungi, but measurements characterizing ectomycorrhizal fungi remain limited. The response after is crucial to understanding biogeochemical cycles plant nutrition. Here, we examined changes in formation, diversity, at the end summer drought events conifer-oak mixed forest under semiarid, Mediterranean-type climate CA, USA. To study effects different amounts...
Abstract To estimate whole‐tree or stand transpiration based on sap flow measurements, flux density ( F d ) needs to be scaled up over the entire sapwood area. We investigated radial variations in dominant oak Quercus liaotungensis and a commonly occurring oriental arborvitae Platycladus orientalis species using Granier‐type thermal dissipation probes semi‐arid forest northern China. Our results show that trees reached maximum just below cambium decreased towards inner sapwood. On other...
