“…Litter fall is an important source of soil carbon for bacteria, and increased plant litter can enhance their abundance (Nottingham and others 2009). The percent tree layer cover can alter features of the soil habitat such as light gaps, air temperature, relative humidity, soil temperature, and soil moisture (Zhang and Zak 1995;Whelan and Anderson 1996). These differences in microclimate could thus alter the growth of certain microbial groups better adapted to those specific conditions.…”

We analyzed the influence of above-and belowground factors on the soil microbial community in a Chinese subtropical forest, one of the most diverse biomes in the northern hemisphere. Soil samples were taken at different depths from four replicate comparative study plots in each of three forest age classes (young 10-40 years, medium 40-80 years, old ‡80 years). Microbial biomass and community structure were then determined using phospholipid fatty acid (PLFA) analysis, and basal respiration and microbial biomass carbon (C mic ) were determined by substrate-induced respiration.These data were then related to plant community and soil variables using non-metric multidimensional scaling analysis and post-hoc permutational correlations. We found that microbial lipid composition and abundance were not related to forest age class. Instead, microbial lipid composition and abundance were related to factors reflecting primary production, i.e., percent litter cover, percent dead wood cover, and percent tree layer cover. Specifically, the relative abundance (mol fraction) of indicators for arbuscular mycorrhizal fungi, Gram-positive and Gram-negative bacteria were positively significantly correlated with percent litter cover. We also found that the biomass of all microbial groups and total PLFA were negatively significantly related to percent deadwood cover. In addition, pH H 2 O was the only soil parameter that was correlated significantly to microbial biomass. Our results indicate that overarching ecological factors such as plant productivity and soil pH are important factors influencing the soil microbial community, both in terms of biomass and of community composition in this subtropical ecosystem.

“…Throughfall, which is the Xow of precipitation water through the forest canopy, can be aVected by canopy architecture, leaf area and rainfall intensity (Lovett et al 1996;Whelan and Anderson 1996). Lichter et al (2000) found that elevated CO 2 increased throughfall volume and caused a signiWcant increase in DOC throughfall deposition, attributed to increased soluble C in foliage grown in elevated CO 2 .…”

Fossil fuel combustion is the primary anthropogenic source of both CO2 and Hg to the atmosphere. On a global scale, most Hg that enters ecosystems is derived from atmospheric Hg that deposits onto the land surface. Increasing concentrations of atmospheric CO2 may affect Hg deposition to terrestrial systems and storage in soils through CO(2)-mediated changes in plant and soil properties. We show, using free-air CO2 enrichment (FACE) experiments, that soil Hg concentrations are almost 30% greater under elevated atmospheric CO2 in two temperate forests. There were no direct CO2 effects, however, on litterfall, throughfall or stemflow Hg inputs. Soil Hg was positively correlated with percent soil organic matter (SOM), suggesting that CO(2)-mediated changes in SOM have influenced soil Hg concentrations. Through its impacts on SOM, elevated atmospheric CO2 may increase the Hg storage capacity of soils and modulate the movement of Hg through the biosphere. Such effects of rising CO2, ones that transcend the typically studied effects on C and nutrient cycling, are an important next phase for research on global environmental change.

“…Along similar lines, Wigmosta et al [119] and Davis et al [125] have used snow patterns in analyses of alpine hydrology models. Moore and Grayson [126] compared observed saturated source areas to simulations from a distributed parameter model in a small laboratory sand bed, while Whelan and Anderson [118] simulated the spatial variability of throughfall and compared it to measurements from an array of ground collectors. As noted above, recent years have seen an increase in the availability of ground-based pattern data from research catchments and from remote sensing, up to the global scale.…”
