Soil Fungal Community Structure and Its Effect on CO Emissions in the Yellow River Delta.

Soil salinization is one of the most compelling environmental problems on a global scale. Fungi play a crucial role in promoting plant growth, enhancing salt tolerance, and inducing disease resistance. Moreover, microorganisms decompose organic matter to release carbon dioxide, and soil fungi also use plant carbon as a nutrient and participate in the soil carbon cycle.

Functional Diversity and CO Emission Characteristics of Soil Bacteria during the Succession of Halophyte Vegetation in the Yellow River Delta.

Carbon dioxide (CO) is the most important greenhouse gas in the atmosphere, which is mainly derived from microbial respiration in soil. Soil bacteria are an important part of the soil ecosystem and play an important role in the process of plant growth, mineralization, and decomposition of organic matter. In this paper, we discuss a laboratory incubation experiment that we conducted to investigate the CO emissions and the underlying bacterial communities under the natural succession of halophyte vegetation in the Yellow River Delta by using high-throughput sequencing technology and PICRUSt functional prediction.

Catabolic Activity and Structural Diversity of Bacterial Community in Soil Covered by Halophytic Vegetation.

The catabolic activity and structural diversity of soil bacteria covered by five different halophytic vegetation types in the Yellow River Delta affected by long-term salinization were studied using Biolog-Eco technology. The result showed that soil quality, the diversity, and catabolic activity of the bacterial community of mildly salt-tolerant vegetation (Imperata cylindrical (L.) Beauv.

A national-scale characterization of organochlorine pesticides (OCPs) in intertidal sediment of China: Occurrence, fate and influential factors.

Organochlorine pesticides (OCPs) have been restricted for application for about 30 years in China. Intertidal zone is a sink for anthropogenic pollutants, and to better understand the current pollution status of OCPs in China, 324 surface sediment samples collected from 14 typical intertidal zones of China were analyzed for 22 OCPs. The total concentrations of OCPs ranged from 0.

Interactive impacts of nitrogen input and water amendment on growing season fluxes of CO, CH, and NO in a semiarid grassland, Northern China.

Nitrogen and water are two important factors influencing GHG (primarily CO - carbon dioxide; CH - methane, and NO - nitrous oxide) fluxes in semiarid grasslands. However, the interactive effects of nitrogen and water on GHG fluxes remain elusive. A 3-year (2010-2012) manipulative experiment was conducted to investigate the individual and interactive effects of nitrogen and water additions on GHG fluxes during growing seasons (May to September) in a semiarid grassland in Northern China.

Effects of mowing on methane uptake in a semiarid grassland in northern China.

Background: Mowing is a widely adopted management practice for the semiarid steppe in China and affects CH(4) exchange. However, the magnitude and the underlying mechanisms for CH(4) uptake in response to mowing remain uncertain.

Methodology/principal Findings: In two consecutive growing seasons, we measured the effect of mowing on CH(4) uptake in a steppe community.

[Spatial diversity index analysis on wildlife habitat pattern change in the Liaohe Delta].

Based on the study of land cover change in the Liaohe Delta with GIS and RS, the wildlife habitat pattern was described quantitatively, and the pattern change between 1988 and 1998 was analyzed with spatial diversity index. The results showed that the wildlife habitat pattern had an obvious change during the ten years caused by natural and human disturbance. The area of suitable habitat(Sd > or = 0.
