“…The reduction in AOA and AOB populations reported here may be an underestimation, due to the detection of DNA from recently dead cells (Bakken 1997;Cavagnaro et al 2008;Chabrerie et al 2003), or from slow-growing or dormant cells (Balaban et al 2004). Thus, studies of RNA from AOA and AOB in these and other soils may be especially valuable in further exploring this issue.…”

Inhibitory experiments were conducted to investigate the responses of the population sizes of ammonia-oxidizing archaea (AOA) and bacteria (AOB) and the potential nitrification rates (PNRs) to Cu contamination in four Chinese soils. PNR was determined using a substrate-induced nitrification (SIN) assay, and the population size of the nitrifiers represented by amoA gene abundances was quantified using a real-time polymerase chain reaction (qPCR) assay. Both population size and PNR of the ammonia oxidizers reduced considerably at high Cu concentrations in all the soils. Bacterial amoA gene abundance was reduced by from 107-fold (Hailun soil) to more than 232-fold (Hangzhou soil) at the highest Cu concentrations (2,400 mg kg −1 Cu for Hailun, Langfang and Guangzhou soils and 1,600 mg kgCu for Hangzhou soil), while reduction in archaeal amoA gene abundance was from 10-fold (Langfang soil) to 89-fold (Hangzhou soil). AOA seemed more tolerant to Cu contamination than AOB. Nitrification rates were inhibited by more than 50% at a Cu concentration of 600 mg kg −1 , and by more than 90%at the highest Cu concentrations in all soils. These results indicated that both AOA and AOB can be inhibited by toxic metals, highlighting the need to consider the role of AOA in nitrification in soils.

“…This result is surprising because treatments applied during two summer periods seem to have been more important to change microbial activities than the presence of an ecological gradient acting since decades. However there are two possible explanations: (i) the microbial communities were indeed physiologically equivalent as suggested results of Chabrerie et al (2003) who found that microbial activities were independent from vegetation type in terms of functional and genetic structure; (ii) the Ecoplateä is not sensitive enough to detect such differences. It is obvious that with this method we obtain only a partial view of the active and fast growing bacterial community (Konopka et al, 1998;Verschuere et al, 1997).…”

“…Microbial communities seem to be weakly related to the studied successional gradient of vegetation in terms of functional structure and indeed, for chalk grassland Chabrerie et al (2003) came to the conclusion of independency. In some cases, microbial community structure (PLFA) and activity (Biologä) are more influenced by the soil type than by the plants (Buyer et al, 2002).…”

“…Much research effort has been directed at understanding how agriculture and land use practice influence the structure and diversity of animal and microbial below-ground communities (Chabrerie et al, 2003;Clegg et al, 2003;Grayston et al, 2004;Larkin, 2003). The role of soil organisms in regulating ecosystem processes has received growing attention over the past several years and there is an increasing number of studies on questions such as how decomposers respond to disturbance regimes especially those related to agriculture (Guitian and Bardgett, 2000;Wardle et al, 1999;Yeates et al, 1997).…”

Soil Microbial Community Changes in Wooded Mountain Pastures due to Simulated Effects of Cattle Grazing

The effect of cattle activity on pastures can be subdivided into three categories of disturbances: herbage removal, dunging and trampling. The objective of this study was to assess separately or in combination the effect of these factors on the potential activities of soil microbial communities and to compare these effects with those of soil properties and plant composition or biomass. Controlled treatments simulating the three factors were applied in a fenced area including a light gradient (sunny and shady situation): (i) repeated mowing; (ii) trampling; (iii) fertilizing with a liquid mixture of dung and urine. In the third year of the experiment, community level physiological profiles (CLPP) (Biolog Ecoplatesä) were measured for each plots. Furthermore soil chemical properties (pH, total organic carbon, total nitrogen and total phosphorus), plant species composition and plant biomass were also assessed. Despite differences in plant communities and soil properties, the metabolic potential of the microbial community in the sunny and in the shady situations were similar. Effects of treatments on microbial communities were more pronounced in the sunny than in the shady situation. In both cases, repeated mowing was the first factor retained for explaining functional variations. In contrast, fertilizing was not a significant factor. The vegetation explained a high proportion of variation of the microbial community descriptors in the sunny situation, while no significant variation appeared under shady condition. The three components of cattle activities influenced differently the soil microbial communities and this depended on the light conditions within the wooded pasture. Cattle activities may also change spatially at a fine scale and short-term and induce changes in the microbial community structure. Thus, the shifting mosaic that has been described for the vegetation of pastures may also apply for below-ground microbial communities.

“…Consequently, changes in nutrient quality and availability caused by changes in plant diversity are expected to alter the number, activities and diversity of soil microorganisms (Hooper et al 2000). Although each stage of succession was characterized by a particular plant species assemblage, Chabrerie et al (2003) found that microbial communities show a degree of resilience with respect to changes in plant community composition. Similarly, our findings show that there is no direct link between plant and microbial taxonomic diversity.…”

The hypothesis that positive links exist among plant taxonomic diversity, belowground microbial taxonomic and metabolic diversities was tested for four secondary vegetation successional stages (tussock (T), shrub (S), secondary forest (SF) and primary forest (PF)) in Huanjiang county, SW China. Soil bacterial communities were characterized by DNA fingerprinting and metabolic profiling. Along the succession, Shannon diversity indices followed the order SF>PF>S>T for plant taxonomic diversity, T>SF>PF>S for bacterial operational taxonomic diversity, SF>T>S>PF for fungal operational taxonomic diversity, and SF>PF>S>T for bacterial metabolic diversity. Significant positive correlations were found between bacterial and fungal taxonomic diversities. However, there was no significant correlation between soil microbial taxonomic diversity and bacterial metabolic diversity. Two-way ANOVA revealed that vegetation and season, as well as their interaction, had significant effects on soil microbial (fungal and bacterial) taxonomic diversities, but that there were no seasonal effects on metabolic diversity. However, PCA and MANOVA revealed highly significant differences among the bacterial community-level physiological profiles, reflecting the successional sequence. The findings from this survey support the notion that there are strong interactions between aboveground and belowground communities and suggest that bacterial metabolic and plant taxonomic diversities, but not microbial taxonomic and metabolic diversities, can be correlated.
