“…In this study, SMB-C and SMA were higher in July than in May and September in all three forests, reflecting that substrate availability must have varied considerably during the growing season. Similar findings were also observed in other studies (Wardle, 1998;Michelsen et al, 2004;Shishido et al, 2008).…”

Abstract.We report the first estimates of pools and dynamics of microbes, roots, plant litter and soil organic carbon (SOC) in three dominant types of China's vast deciduous forest area: Betula platyphylla, Quercus liaotungensis, and Quercus aliena var. acuteserrata. Organic matter degradation rates overshadowed litter inputs as the main determinant of the soil carbon stocks. Across the three forests, rates of litter decomposition were also indicative for turnover rates of SOC. Litter and SOC decay was faster in the subtropical than in the warm-temperate forests. Among the latter, SOC turnover was highest in the forest producing the higher-quality litter. Microbial biomass was, as expected, correlated with SOC content. Microbial activity, in contrast, was highest at the sub-tropical forest, despite the lower SOC availability, lower fraction of labile SOC, and lower soil microbial biomass. These results may contribute to increased understanding of controls over belowground carbon cycling in deciduous forests.

“…Because Rh accounts for about 50%–80% of Rs (Luo & Zhou, ) and insect/pathogen outbreaks significantly increased the population sizes of both bacteria and fungi (Fig. ; Shishido et al ., ), biotic disturbance significantly stimulated Rh (Figs c & ). For Ra , it is difficult to evaluate the effects of biotic disturbance due to the limited data (Fig.…”

Aim Climate change, especially the wider occurrence of extreme events, is likely to increase the intensity and frequency of insect/pathogen outbreaks (referred to as biotic disturbance), which may considerably affect plant ecophysiological traits and thus the ecosystem carbon (C) cycle. Little is known, however, about the ways in which biotic disturbance quantitatively affects ecosystem C processes, especially those that occur below ground. We reveal the general patterns of below-ground C responses to biotic disturbance from field manipulative experiments and opportunistic events. Location Global.Method We carried out a meta-analysis examining the effects of biotic disturbance on 16 variables associated with below-ground C processes, based on 64 experimental studies.Results Biotic disturbance significantly decreased below-ground C pools with relatively long residence times (e.g. root biomass and soil organic carbon, SOC), but increased labile C pools (e.g. microbial biomass carbon, MBC; dissolved organic carbon, DOC), soil respiration (Rs) and its components, and microbial population sizes. Compared with the neutral or positive effects of other environmental changes on below-ground C pools and fluxes, biotic disturbance had a negative effect on plant biomass and SOC but a larger positive effect on MBC, DOC and Rs.Main conclusions Biotic disturbance can have stronger impacts on belowground C processes than other environmental changes, and the sensitive responses of soil labile C pools and C fluxes to biotic disturbance decrease long-term belowground C sequestration. More research efforts are, however, needed to reduce the uncertainties in quantifying the effects of biotic disturbance and to improve forecasting of the feedback between the carbon cycle and climate.

“…There is paucity of information on the characteristics of soil microbial communities in agroecosystems, particularly in the semi-arid regions of the world growing crops in drylands. Microbial communities have great potential for temporal or spatial change, and therefore understanding their community dynamics is important in both basic and applied ecological contexts (Derry et al, 1999;Diosma et al, 2006;Esperschutz et al, 2007;Nannipieri et al, 2008;Shishido et al, 2008;Wu et al, 2008;Nautiyal et al, 2010). A rapid, community level approach for assessing patterns of sole carbon source utilization by mixed microbial samples has been used to study microbial community dynamics (Diosma et al, 2006;Nautiyal et al, 2010).…”
