“…Differences in the chemical composition of decomposing litter, depending on type of leaf litter, and decaying stages of litter and wood may have considerable effects on litter arthropod populations [48]. Thick organic layers also offer increased habitat space for soil fauna [24,38] and reduce temperature and temperature variability among seasons, protecting animals more susceptible to drought and high temperatures [3,6,8].…”

t r a c tThe main objective of this study is to assess the soil diversity and temporal and spatial distribution of litter macro-arthropods, captured with pitfall traps, on different vegetation covers from Porto Santo Island (Portugal) with different soil physical and chemical characteristics. The PCA clearly separated sampling areas geographically more exposed to winds and solar radiation, from the others that were not. In this analysis, seasons seemed to have no influence on this distribution. Non-exposed areas were characterized by high soil temperatures, water and organic matter contents. Among these areas, those that were covered by Pinus halepensis and Eucalyptus ficifolia showed the highest C/N ratios in winter, which may be explained by likely inhibitory effects of phenolic compounds of the leaves of both species on the decomposition process. The highest number of organisms was recorded on the exposed areas. Variance partitioning using CCA showed that the different vegetation covers and environmental variables explained 19% and 30%, respectively, of the variance in macro-arthropods distribution. Four environmental variables (exposure, temperature, C/N ratio and exchangeable K) were positively correlated with the taxa abundance matrix. The results showed that non-exposed areas with E. ficifolia and Cupressus macrocarpa seemed to favour the establishment of a high diversity of taxa, especially in the summer, when soil conditions tend to be extreme.

“…In the research of Chan et al (1997), two landfill sites in Hong Kong (Shuen Wan and Junk Bay StageI) were chosen as the field sites and three sites (Yuen Chau Kok, Tai Po and Lok Wo Sha) were chosen as reference sites. The vegetation survey classified the plants under woody plants, herbs and grasses groups.…”

“…Tree cover on the landfill sites was dominated by two species: Acacia confusa and Leucaena leucocephala, which seemed suited for growth and were abundant on landfill sites. Therefore, completed landfill sites can be good habitats, which support a variety of plants and animals, provided that the plants can phytoremediate landfill gas and leachate contamination (Chan et al, 1997).…”

Biogas in landfill is being captured by natural and engineered processes. The natural processes are represented by biological activities such as bacterial methane oxidation and plant uptake for carbon dioxide at topsoil layer. Landfill gas is transported through soil layers in landfill top or in nearby areas before being released to the atmosphere. Whilst transported in the soil layers the biogas is mixed with atmospheric air and the methane may hence be oxidized by the methanotrophic bacteria in the soil using oxygen from atmosphere. Methane oxidation is affected by different environmental factors such as; temperature, water content, nutrients, substrate and oxygen concentrations. One of the ways to decrease greenhouse emissions in the future is to plant fast growing woody crops thereby sequestering carbon and displacing fossil fuels by harvesting woody biomass for bio-energy, or by storing carbon in long-lived woody products. Plant uptake for carbon dioxide is affected by some parameters such as; CO 2 concentration, nitrogen concentration, water content and temperature. The engineered processes are represented by various physical biogas extractions; gas is collected using network of collection pipes and wells. The gas collection efficiency in landfills is between 40-90%. Landfill gas can be collected by either a passive or an active collection system. Passive gas collection systems use existing variations in landfill pressure and gas concentrations to vent landfill gas into the atmosphere or a control system. Active gas collection is considered a good means of landfill gas collection. An active collection system composed of extraction wells connected to header pipe to a pump that delivers gas for energy recovery.

“…In South Korea, there are approximately 800 waste landfills (KORECO, 1995) which produce biogas and landfill leachate during waste decomposition (Chan et al, 1997). These are two pollutant emissions that contaminate landfill itself and surrounding environment, including underlying soil (Ahel et al, 1998).…”

A floristic survey was conducted in turf-dominated fields on some waste landfills in South Korea, to quantify the degree of plant invasion in those degraded lands. The dominant species, except turf (Zoysia japonica), were Conyza canadensis, Setaria viridis, Digitaria sanguinalis and Aster tripolium. Mean species number declined linearly with distance from the edge of the turf stands. Biomass of each species ranged between 0Á1 g and 122Á6 g, decreasing linearly with distance from the edge of the stand and declining exponentially with turf coverage. Mean soil moisture storage and organic matter content were 12Á59 per cent and 5Á81 per cent, respectively. Sum of relative cover, frequency and biomass of all species with environmental variables (distance from the stand edge, turf cover, soil moisture storage, soil organic matter content and the ratio of species number of exotic plants to that of native plants) were ordinated by DCA (detrended correspondence analysis). The first axis of the DCA was positively correlated with distance from the stand edge and turf cover and the second axis of the DCA was negatively correlated with soil organic matter content. Highly and lowly invasive species were indicated from DCA results. From analysis of dispersal type, barochore and anemochore were the most widespread of other dispersal types but it was suggested that anthropochore played an important role in plant invasion in these degraded wastelands. Establishment of an edge transition zone, enhancement of turf cover and reduction in traffic is recommended as management options for turf fields.
