Understanding anthropogenic influences on soil respiration (Rs) is critical for accurate predictions of soil carbon fluxes, but it is not known how Rs responds to grazing exclusion (GE). Here, we conducted a manipulative experiment in a meadow grassland on the Tibetan Plateau to investigate the effects of GE on Rs. The exclusion of livestock significantly increased soil moisture and above\uffe2\uff80\uff90ground biomass, but it decreased soil temperature, microbial biomass carbon (MBC), and Rs. Regression analysis indicated that the effects of GE on Rs were mainly due to changes in soil temperature, soil moisture, and MBC. Compared with the grazed blocks, GE significantly decreased soil carbon release by 23.6% over the growing season and 21.4% annually, but it increased the temperature sensitivity (Q10) of Rs by 6.5% and 14.2% for the growing season and annually respectively. Therefore, GE may reduce the release of soil carbon from the Tibetan Plateau, but under future climate warming scenarios, the increases in Q10 induced by GE could lead to increased carbon emissions.

Experimental NO 3 \u2212 deposition (3 g NO 3 \u2212 N m\u22122 y\u22121) has significantly reduced soil respiration and increased the export of DOC/DON and NO 3 \u2212 across the region. Here, we evaluate the possibility that diminished microbial activity in mineral soil was responsible for these ecosystem-level responses to NO 3 \u2212 deposition. To test this alternative, we measured microbial biomass, respiration, and N transformations in the mineral soil of four northern hardwood stands that have received 9 years of experimental NO 3 \u2212 deposition. Microbial biomass, microbial respiration, and daily rates of gross and net N transformations were not changed by NO 3 \u2212 deposition. We also observed no effect of NO 3 \u2212 deposition on annual rates of net N mineralization. However, NO 3 \u2212 deposition significantly increased (27%) annual net nitrification, a response that resulted from rapid microbial NO 3 \u2212 assimilation, the subsequent turnover of NH 4 + , and increased substrate availability for this process. Nonetheless, greater rates of net nitrification were insufficient to produce the 10-fold observed increase in NO 3 \u2212 export, suggesting that much of the exported NO 3 \u2212 resulted directly from the NO 3 \u2212 deposition treatment. Results suggest that declines in soil respiration and increases in DOC/DON export cannot be attributed to NO 3 \u2212 -induced physiological changes in mineral soil microbial activity. Given the lack of response we have observed in mineral soil, our results point to the potential importance of microbial communities in forest floor, including both saprotrophs and mycorrhizae, in mediating ecosystem-level responses to chronic NO 3 \u2212 deposition in Lake States northern hardwood forests.", "keywords": ["0106 biological sciences", "Ecology", "Science", "Plant Sciences", "Soil C and N Cycling", "Ecology and Evolutionary Biology", "Life Sciences", "Natural Resources and Environment", "Nature Conservation", "Northern Hardwood Forests", "04 agricultural and veterinary sciences", "15.

However, the compensatory thermal adaptation of soil microorganisms and substrate depletion may weaken the effects of rising temperature on soil respiration. To test this hypothesis, we collected soils along a large-scale forest transect in eastern China spanning a natural temperature gradient, and we incubated the soils at different temperatures with or without substrate addition. We combined the exponential thermal response function and a data-driven model to study the interaction effect of thermal adaptation and substrate availability on microbial respiration and compared our results to those from two additional continental and global independent datasets. Modeled results suggested that the effect of thermal adaptation on microbial respiration was greater in areas with higher mean annual temperatures, which is consistent with the compensatory response to warming. In addition, the effect of thermal adaptation on microbial respiration was greater under substrate addition than under substrate depletion, which was also true for the independent datasets reanalyzed using our approach. Our results indicate that thermal adaptation in warmer regions could exert a more pronounced negative impact on microbial respiration when the substrate availability is abundant. These findings improve the body of knowledge on how substrate availability influences the soil microbial community\uffe2\uff80\uff93temperature interactions, which could improve estimates of projected soil carbon losses to the atmosphere through respiration.Microbial decomposition of soil organic matter produces a major flux of CO2 from terrestrial ecosystems and can act as a feedback to climate change. Although climate\uffe2\uff80\uff90carbon models suggest that warming will accelerate the release of CO2 from soils, the magnitude of this feedback is uncertain, mostly due to uncertainty in the temperature sensitivity of soil organic matter decomposition. We examined how warming and altered precipitation affected the rate and temperature sensitivity of heterotrophic respiration (Rh) at the Boston\uffe2\uff80\uff90Area Climate Experiment, in Massachusetts, USA. We measured Rh inside deep collars that excluded plant roots and litter inputs. In this mesic ecosystem, Rh responded strongly to precipitation. Drought reduced Rh, both annually and during the growing season. Warming increased Rh only in early spring. During the summer, when Rh was highest, we found evidence of threshold, hysteretic responses to soil moisture: Rh decreased sharply when volumetric soil moisture dropped below ~15% or exceeded ~26%, but Rh increased more gradually when soil moisture rose from the lower threshold. The effect of climate treatments on the temperature sensitivity of Rh depended on the season. Apparent Q10 decreased with high warming (~3.5\uffc2\uffa0\uffc2\uffb0C) in spring and fall. Presumably due to limiting soil moisture, warming and precipitation treatments did not affect apparent Q10 in summer. Drought decreased apparent Q10 in fall compared to ambient and wet precipitation treatments. To our knowledge, this is the first field study to examine the response of Rh and its temperature sensitivity to the combined effects of warming and altered precipitation. Our results highlight the complex responses of Rh to soil moisture, and to our knowledge identify for the first time the seasonal variation in the temperature sensitivity of microbial respiration in the field. We emphasize the importance of adequately simulating responses such as these when modeling trajectories of soil carbon stocks under climate change scenarios.

Major taxa studiedMicrobial community (fungi and bacteria).
MethodsWe collected 881 soil samples from across Europe in the framework of the Land Use/Land Cover Area Frame Survey (LUCAS). We measured potential soil basal respiration at 20\uffc2\uffa0\uffc2\uffbaC and microbial biomass (substrate\uffe2\uff80\uff90induced respiration) using an O2\uffe2\uff80\uff90microcompensation apparatus. Soil and climate data were obtained from the same LUCAS survey and online databases. Structural equation models (SEMs) were used to quantify relationships between variables, and equations extracted from SEMs were used to create predictive maps. Fatty acid methyl esters were measured in a subset of samples to distinguish fungal from bacterial biomass.
ResultsSoil microbial properties in croplands were more heavily affected by climate variables than those in forests. Potential soil basal respiration and microbial biomass were correlated in forests but decoupled in grasslands and croplands, where microbial biomass depended on soil carbon. Forests had a higher ratio of fungi to bacteria than grasslands or croplands.
Main conclusionsSoil microbial communities in grasslands and croplands are likely carbon\uffe2\uff80\uff90limited in comparison with those in forests, and forests have a higher dominance of fungi indicating differences in microbial community composition. Notably, the often already\uffe2\uff80\uff90degraded soils of croplands could be more vulnerable to climate change than more natural soils. The provided maps show potentially vulnerable areas that should be explicitly accounted for in future management plans to protect soil carbon and slow the increasing vulnerability of European soils to climate change.

Changes of 13C/C and 15N/N in soils, earthworms, and microbial populations were analyzed to evaluate resource utilization by earthworms and their influences on C and N dynamics. Estherella spp. utilized the 13C-labeled litter; however, its utilization on the 13C-labeled litter reduced when cultivated with P. corethrurus and O. borincana. Both P. corethrurus and O. borincana utilized the 13C-labeled litter and 15C-labeled grass roots and root exudates. Pontoscolex corethrurus facilitated soil respiration by stimulating 13C-labeled microbial activity; however, this effect was suppressed possibly due to the changes in the microbial activities or community when coexisting with O. borincana. Increased soil N mineralization by individual Estherella spp. and O. borincana was reduced in the mixed-species treatments. The rapid population growth of P. corethrurus may increase competition pressure on food resources on the local earthworm community. The relevance of resource availability to the population growth of P. corethrurus and its significance as an invasive species is a topic in need of future research.

Biocrusts are prevalent and participate in many soil organic carbon (C) processes in drylands. The predicted increase in aridity will expand the biocrust cover and significantly impact soil organic C dynamics. However, how biocrusts change soil organic C decomposition and what factors drive the effect in response to climate warming remains largely unknown at a continental scale. 2. We measured microbial respiration and its temperature sensitivity (Q10) in bare soil lacking biocrusts and two universal biocrusted soils (cyanobacterial- and moss-crusted soil) from 43 sites across a precipitation gradient from 39 mm to 443 mm to evaluate the relative effects of biocrusts on Q10 and the driving forces in northern China\u2019s dryland. 3. Microbial respiration increased and Q10 decreased with increasing precipitation in bare soil, cyanobacterial- and moss-crusted soil. Biocrusts positively affected microbial respiration, with a more substantial magnitude by moss crusts than cyanobacterial crusts. Biocrusts negatively impacted Q10, and the magnitudes were similar between moss and cyanobacterial crusts. Most importantly, the relative effects of biocrusts on microbial respiration and Q10 increased with decreasing precipitation. 4. The positive effects of biocrusts on soil organic C content and microbial biomass carbon were positively correlated with the level of increased microbial respiration. Contrastingly, the magnitude of reduced Q10 was attributed to the biocrusts\u2019 positive effects on soil organic C quality and adverse effects on the ratio of fungal to bacterial PLFAs (F: B). 5. Our study provides strong evidence that biocrusts decrease the temperature sensitivity of microbial respiration in northern China\u2019s dryland. This result suggests that the predicted expanding biocrust cover is crucial for maintaining the soil organic C stability by buffering the positive impacts of climate warming on soil organic C decomposition in drylands.", "keywords": ["2.

Six agricultural fields located in two of the main banana production areas of Venezuela were selected. The experimental sites were in large farms (\u2265\u200950 ha) with four productivity levels in \u201cGran Nain\u201d bananas, with an area of 4 ha for each of four productive levels: High - High, High - Low, Low - High, and Low - Low. Sixty sampling points were used to characterize the soils under study. Additionally, a Productivity Index (PI) based on three different biometric data on plant productivity was proposed. Through hierarchical statistical analysis, the first 16 soil variables that best explained the PI were selected. Thus, five multiple linear regression models were estimated, using the stepwise regression method. Subsequently, a performance analysis was used to compare the prediction quality range and the error associated with the number of soil variables selected for the proposed models. The selected model included the following soil variables: Mg, penetration resistance, total microbial respiration, bulk density, and omnivorous free-living nematodes. These variables explain the PI with an R2 of 0.55, the mean absolute error (MAE) of 0.8, and the root of the mean squared error (RMSE) of 1.0. The five selected variables are proposed to characterize the soil Productivity Index in banana and could be used in a site-specific soil management program for the banana areas of Venezuela.

While this has resulted in large ecological changes aboveground such as altered tree species composition and increased forest density, little is known about the long-term, belowground implications of altered, ecologically novel fire regimes, especially on soil biological processes. To better understand the long-term implications of ecologically novel, high-severity fire, we used a 44-y high-severity fire chronosequence in the Sierra Nevada where forests were historically adapted to frequent, low-severity fire, but were fire suppressed for at least 70 years. High-severity fire in the Sierra Nevada resulted in a long-term (44+ y) decrease (>50%, p < 0.05) in soil extracellular enzyme activities, basal microbial respiration (56-72%, p < 0.05), and organic carbon (>50%, p < 0.05) in the upper 5 cm compared to sites that had not been burned for at least 115 y. However, nitrogen (N) processes were only affected in the most-recent fire site (4 y post-fire). Net nitrification increased by over 600% in the most recent fire site (p < 0.001), but returned to similar levels as the unburned control in the 13-y site. Contrary to previous studies, we did not find a consistent effect of plant cover type on soil biogeochemical processes in mid-successional (10-50 y) forest soils. Rather, the 44-y reduction in soil organic carbon (C) quantity correlated positively with dampened C cycling processes. Our results show the drastic and long-term implication of ecologically novel, high-severity fire on soil biogeochemistry and underscore the need for long-term fire ecological experiments.", "keywords": ["soil organic carbon", "soil biogeochemistry", "microbial biomass", "microbial respiration", "13.

However, the compensatory thermal adaptation of soil microorganisms and substrate depletion may weaken the effects of rising temperature on soil respiration. To test this hypothesis, we collected soils along a large-scale forest transect in eastern China spanning a natural temperature gradient, and we incubated the soils at different temperatures with or without substrate addition. We combined the exponential thermal response function and a data-driven model to study the interaction effect of thermal adaptation and substrate availability on microbial respiration and compared our results to those from two additional continental and global independent datasets. Modeled results suggested that the effect of thermal adaptation on microbial respiration was greater in areas with higher mean annual temperatures, which is consistent with the compensatory response to warming. In addition, the effect of thermal adaptation on microbial respiration was greater under substrate addition than under substrate depletion, which was also true for the independent datasets reanalyzed using our approach. Our results indicate that thermal adaptation in warmer regions could exert a more pronounced negative impact on microbial respiration when the substrate availability is abundant. These findings improve the body of knowledge on how substrate availability influences the soil microbial community\uffe2\uff80\uff93temperature interactions, which could improve estimates of projected soil carbon losses to the atmosphere through respiration.
