Macrofauna data on post-fire peat soils have been documented in many literatures, but assessments of soil macrofauna recovery peatlands after one and a half years fires are scarce. The aim this study was to evaluate the fires. This research conducted land PT.SSS Kuala Panduk Teluk Meranti District, Pelalawan Regency. by survey method. Determination location using purposive sampling method, espe...

An investigation on soil organic carbon,total N and NO3--N,available microbial biomass C,N and basal respiration and metabolic quotients(qCO2)was conducted to compare diferences in soil microbial properties and nutrients between 1 5-year-old pure Chi— nese fir(Cunninghamia lanceolata)and two mixed Chinese fir plantations(mixed plantations with A/nus cremastogyne,mixed plantations with Kalopanax...

There is increasing evidence showing that microbes can influence plant-insect interactions. In addition, various studies have shown that aboveground pathogens can alter the interactions between plants and insects. However, little is known about the role of soil-borne pathogens in plant-insect interactions. It is also not known how environmental conditions, that steer the performance of soil-bor...

Plant diversity drives changes in the soil microbial community which may result in alterations in ecosystem functions. However, the governing factors between the composition of soil microbial communities and plant diversity are not well understood. We investigated the impact of plant diversity (plant species richness and functional group richness) and plant functional group identity on soil mic...

Organic amendments may improve the quality of acidic tropical agricultural soils with low organic carbon contents under conventional management (mineral fertilization and irrigation) in Southeast Asia. We investigated effect biochar, compost their combination on maize growth yield, soil physical, biological chemical properties at harvesting time four sites three countries: Thailand, Vietnam Lao...

The objectives of this study were to provide data that can be used to predict exposure-based effects of RDX in aged soil on multiple endpoint organisms representing two trophic levels. These data can be used for defining criteria or reference values for environmental management and conducting specific risk assessment. Dose-response experiments formed the basis for the evaluation of toxic effect...

BACKGROUND Since Spartina alterniflora (simplified as Spartina) has strong ecological competitiveness and rapid growth, it has been introduced and living in the coastal wetland regions of China for more than 30 years. Taking coastal wetland in the Beibu Gulf of south China as an example, the effects of Spartina invasion on soil quality were investigated to provide scientific basis for soil mana...

Five separate test sites were established in 1994 to evaluate the use of municipal sewage sludge as a soil amendment and conditioner (hereafter referred to as “biosolids”) on the Kennecott Utah Copper Corporation’s tailings impoundment near Magna, Utah. Each site was divided into 16 test plots to evaluate four replications of the four rates of biosolids addition and incorporation into the taili...

The general utility of large-scale artificial ecosystems for ecological and ecotoxicological research is evaluated by a case study of the replicability, repeatability and ecological realism of a Baltic Sea hard bottom littoral mesocosm (called BHB-mesocosm). The structure (species abundance and biomass listings) of the macrofauna community associated with bladder-wrack, Fucus vesiculosus L., in...

In this study soil properties and root biomass responses to prescribed fire were investigated in 25-30 year-old calabrian pine (Pinus brutia Ten.) stands in Edirne, Turkey. The stands were established by planting and were subjected to prescribed burning in July 2005. Soil respiration rates were determined every two months using the soda-lime method over a two-year period. Fine (> or = 2 mm diam...
