The concept of root contact hypothesizes that the absorbing roots grown in sandy soil are only partially effective in water uptake. Co-ordination of water supply and demand in the plant requires that the capacity for water uptake from the soil should correspond to an operational rate of water loss from the leaves. To examine how the plant hydraulic system responds to variations in soil texture ...

Large-scale vegetation restoration in China’s Loess Plateau has been initiated by the central government for controlling soil andwater losses in the past three decades. However, there is virtually no guidance for plant species selection for the restoration purpose. We investigated the effects of planting trees and shrubs, land-use conversions from croplands to pastures and native grasslands on ...

The biogeographical distribution of soil bacterial communities has been widely investigated. However, there has been little study of the biogeography of soil archaeal communities on a regional scale. Here, using high-throughput sequencing, we characterized the archaeal communities of 94 soil samples across the eastern Tibetan Plateau. Thaumarchaeota was the predominant archael phylum in all the...

The pupal development of Aethina tumida Murray (Coleoptera: Nitidulidae) was studied at various combinations of thermo-hygrometric soil conditions (temperatures of 16, 18, and 20 C and soil water content levels of 0.37, 0.56, and 0.73 m water per cubic meter of dry soil) representative of southeastern Canada. Survivorship and development duration of A. tumida pupae, as well as sex ratio and lif...

Listeria monocytogenes is a food-borne pathogen responsible for the potentially fatal disease listeriosis and terrestrial ecosystems have been hypothesized to be its natural reservoir. Therefore, identifying the key edaphic factors that influence its survival in soil is critical. We measured the survival of L. monocytogenes in a set of 100 soil samples belonging to the French Soil Quality Monit...

PS silt mixed soil is a high quality synthetic fill material made of foam material and sludge wasted. This paper indicates according to the test results and the previous studies that: the intensity of light-weight soils is increasing as the grey water ratio increases, and when the gray water ratio reaches a certain value, the strength of the growth rate is not large. Therefore, the research of ...

The global atmospheric carbon dioxide (CO₂) concentration is expected to increase continuously over the next century. However, little is known about the responses of soil bacterial communities to elevated CO₂ in terrestrial ecosystems. This study aimed to partition the relative influences of CO₂, nitrogen (N), and the spatial factor (different sampling plots) on soil bacterial communities at th...

Land use change alters the structure and composition of microbial communities. However, the links between environmental factors and microbial functions are not well understood. Here we interrogated the functional structure of soil microbial communities across different land uses. In a multivariate regression tree analysis of soil physicochemical properties and genes detected by functional micro...

Land application of coalbed natural gas (CBNG) co-produced water is a popular management option within northwestern Powder River Basin (PRB) of Wyoming. This study evaluated the impacts of land application of CBNG waters on soil chemical properties at five sites. Soil samples were collected from different depths (0-5, 5-15, 15-30, 30-60, 60-90, and 90-120 cm) from sites that were irrigated with...
