Responses of alpine tree line ecosystems to increasing atmospheric CO2 concentrations and global warming are poorly understood. We used an experiment at the Swiss tree line to investigate changes in vegetation biomass after 9\uffc2\uffa0years of free air CO2 enrichment (+200\uffc2\uffa0ppm; 2001\uffe2\uff80\uff932009) and 6\uffc2\uffa0years of soil warming (+4\uffc2\uffa0\uffc2\uffb0C; 2007\uffe2\uff80\uff932012). The study contained two key tree line species, Larix decidua and Pinus uncinata, both approximately 40\uffc2\uffa0years old, growing in heath vegetation dominated by dwarf shrubs. In 2012, we harvested and measured biomass of all trees (including root systems), above\uffe2\uff80\uff90ground understorey vegetation and fine roots. Overall, soil warming had clearer effects on plant biomass than CO2 enrichment, and there were no interactive effects between treatments. Total plant biomass increased in warmed plots containing Pinus but not in those with Larix. This response was driven by changes in tree mass (+50%), which contributed an average of 84% (5.7\uffc2\uffa0kg\uffc2\uffa0m\uffe2\uff88\uff922) of total plant mass. Pinus coarse root mass was especially enhanced by warming (+100%), yielding an increased root mass fraction. Elevated CO2 led to an increased relative growth rate of Larix stem basal area but no change in the final biomass of either tree species. Total understorey above\uffe2\uff80\uff90ground mass was not altered by soil warming or elevated CO2. However, Vaccinium myrtillus mass increased with both treatments, graminoid mass declined with warming, and forb and nonvascular plant (moss and lichen) mass decreased with both treatments. Fine roots showed a substantial reduction under soil warming (\uffe2\uff88\uff9240% for all roots <2\uffc2\uffa0mm in diameter at 0\uffe2\uff80\uff9320\uffc2\uffa0cm soil depth) but no change with CO2 enrichment. Our findings suggest that enhanced overall productivity and shifts in biomass allocation will occur at the tree line, particularly with global warming. However, individual species and functional groups will respond differently to these environmental changes, with consequences for ecosystem structure and functioning.

In this study, our main objective was to compare the release of CO2 from eroded topsoils and from the sediments exported by diffuse erosion during an entire rainy season. Conventional tillage (CT) and no-tillage (NT) maize treatments were considered in an attempt to set up best management practices to mitigate gaseous OC losses from agricultural soils.

Here we analyse a 49-year record of tree dynamics from 24 old-growth forest plots encompassing a broad climatic gradient across the Australian moist tropics and find that annual tree mortality risk has, on average, doubled across all plots and species over the last 35\u00a0years, indicating a potential halving in life expectancy and carbon residence time.

Plots in less moist local climates presented higher average mortality risk, but local mean climate did not predict the pace of temporal increase in mortality risk. Species varied in the trajectories of their mortality risk, with the highest average risk found nearer to the upper end of the atmospheric vapour pressure deficit niches of species.

A 3-year field experiment was conducted from 2010 to 2012 to investigate combined effect of straw and microbial inoculant on methane (CH4) and nitrous oxide (N2O) emissions, global warming potential (GWP) and greenhouse gas intensity (GHGI) in a rice field in Jurong, Jiangsu Province, China. The experiment was designed to have treatment NPK (N, P and K fertilizers only), treatment NPKS (NPK plus wheat straw), treatment NPKSR (NPKS plus Ruilaite microbial inoculant) and treatment NPKSJ (NPKS plus Jinkuizi microbial inoculant). Results show that compared to NPK, NPKS increased seasonal CH4 emission by 280-1370%, while decreasing N2O emission by 7-13%. When compared with NPKS, NPKSR and NPKSJ increased seasonal CH4 emission by 7-13% and 6-12%, respectively, whereas reduced N2O emission by 10-27% and 9-24%, respectively. The higher CH4 emission could be attributed to the higher soil CH4 production potential triggered by the combined application of straw and microbial inoculant, and the lower N2O emission to the decreased inorganic N content. As a whole, the benefit of lower N2O emission was completely offset by increased CH4 emission, resulting in a higher GWP for NPKSR (5-12%) and NPKSJ (5-11%) relative to NPKS. Due to NPKSR and NPKSJ increased rice grain yield by 3-6% and 2-4% compared to NPKS, the GHGI values for NPKS, NPKSR and NPKSJ were comparable. These findings suggest that incorporating straw together with microbial inoculant would not influence the radiative forcing of rice production in the terms of per unit of rice grain yield relative to the incorporation of straw alone.", "keywords": ["2.

Here, we studied arable soil earthworm communities on wheat fields across a European climatic gradient, covering nine pedo\uffe2\uff80\uff90climatic zones, from Mediterranean to Boreal (S to N) and from Lusitanian to Pannonian (W to E). In each zone, 20\uffe2\uff80\uff9325 wheat fields under conventional or organic farming were sampled. Community metrics (total abundance, fresh mass, and species richness and composition) were combined with data on climate conditions, soil properties, and field management and analyzed with mixed models. There were no statistically discernible differences between organic and conventional farming for any of the community metrics. The effects of refined arable management factors were also not detected, except for an elevated proportion of subsurface\uffe2\uff80\uff90feeding earthworms when crop residues were incorporated. Soil properties were not significantly associated with earthworm community variations, which in the case of soil texture was likely due to low variation in the data. Pedo\uffe2\uff80\uff90climatic zone was an overridingly important factor in explaining the variation in community metrics. The Boreal zone had the highest mean total abundance (179\uffe2\uff80\uff89individuals\uffe2\uff80\uff89m\uffe2\uff88\uff922) and fresh mass (86\uffe2\uff80\uff89g\uffe2\uff80\uff89m\uffe2\uff88\uff922) of earthworms while the southernmost Mediterranean zones had the lowest metrics (<1\uffe2\uff80\uff89individual\uffe2\uff80\uff89m\uffe2\uff88\uff922 and <1\uffe2\uff80\uff89g\uffe2\uff80\uff89m\uffe2\uff88\uff922). Within each field, species richness was low across the zones, with the highest values being recorded at the Nemoral and North Atlantic zones (mean of 2\uffe2\uff80\uff933 species per field) and declining from there toward north and south. No litter\uffe2\uff80\uff90dwelling species were found in the southernmost, Mediterranean zones. These regional trends were discernibly related to climate, with the community metrics declining with the increasing mean annual temperature. The current continent\uffe2\uff80\uff90wide warming of Europe and related increase of severe and rapid onsetting droughts will likely deteriorate the living conditions of earthworms, particularly in southern Europe. The lack of interaction between the pedo\uffe2\uff80\uff90climatic zone and the farming system in our data for any of the earthworm community metrics may indicate limited opportunities for alleviating the negative effects of a warming climate in cereal field soils of Europe.Greenhouse gas intensity (GHGI), the evaluation of GHG emissions per unit yield rather than per unit land area, has recently received much attention. Plastic film mulching (PFM) is one of the major agricultural practices in semi-arid areas, but few studies have synthetically studied the effects of PFM on GHGI, grain yield, soil characteristics, and their potential relationships at different winter wheat (Triticum aestivum L.) growing stages. Here in the semi-arid Chinese Loess Plateau, we simultaneously investigated two cropping systems from 2018 to 2020: PFM with 100 % cover and no film mulching (control). Averaged across two growing seasons, the PFM treatment significantly increased soil temperature, water-filled pore spaces and soil water storage, while sustaining high aboveground biomass (31.9 %) and grain yield (45.5 %). The PFM treatment significantly increased cumulative N2O emissions by 56.2 %, CO2 emissions by 39.7 %, and CH4 uptake by 151.4 % compared to the control treatment. GHGI are on average 14.2 % lower in the PFM treatment than in the control treatment. Moreover, the PFM treatment significantly improved soil enzyme activities (alkaline phosphatase, catalase, invertase, and urease) and microbial biomass carbon and nitrogen from grain filling to maturity stage. Altogether, the reductions in GHGI suggest that PFM-induced increases in grain yield could outweigh the adverse impacts on GHG emissions, underscoring the potential to apply PFM for sustainable intensification of crop production in semi-arid areas.

Potential environmental impact categories under investigation were Global Warming, Acidification and Terrestrial Eutrophication.

This study aimed to evaluate the effects of forecasted soil moisture scenarios on the avoidance behavior of two invertebrate species (the arthropod Folsomia candida and the soft-bodied oligochaete Enchytraeus crypticus) in soils degraded by different types of anthropogenic metal(loid) contamination (mining soil and agricultural soil affected by industrial chemical wastes). Different soil moisture contents (expressed as % of the soil water holding capacity, WHC) were evaluated: 50% (standard soil moisture conditions for soil invertebrates' tests); 75% (to simulate increasing soil water availability after intense rainfalls and/or floods); 40%, 30%, 25% and 20% (to simulate decreasing soil water availability during droughts). Invertebrates' avoidance behavior and changes in soil porewater major ions and metal(loid)s were assessed after 48\u202fh exposure. Soil incubations induced a general solubilization/mobilization of porewater major ions, while higher soil acidity favored the solubilization/mobilization of porewater metal(loid)s, especially at 75% WHC. Folsomia candida preferred soils moistened at 50% WHC, regardless the soils were contaminated or not and the changing soil porewater characteristics. Enchytraeus crypticus avoided metal(loid) contamination, but this depended on the soil moisture conditions and the corresponding changes in porewater characteristics: enchytraeids lost their capacity to avoid contaminated soils under water stress situations (75% and 20-25% WHC), but also when contaminated soils had greater water availability than control soils. Therefore, forecasted soil moisture scenarios induced by global warming changed soil porewater composition and invertebrates capacity to avoid metal(loid)-contaminated soils.", "keywords": ["2.

Our findings indicate that the stimulation of ecosystem respiration was due to increases in both plant-related and microbial respiration (n\uffe2\uff80\uff89=\uffe2\uff80\uff899) and continued for at least 25\uffe2\uff80\uff89years (n\uffe2\uff80\uff89=\uffe2\uff80\uff89136). The magnitude of the warming effects on respiration was driven by variation in warming-induced changes in local soil conditions, that is, changes in total nitrogen concentration and pH and by context-dependent spatial variation in these conditions, in particular total nitrogen concentration and the carbon:nitrogen ratio. Tundra sites with stronger nitrogen limitations and sites in which warming had stimulated plant and microbial nutrient turnover seemed particularly sensitive in their respiration response to warming. The results highlight the importance of local soil conditions and warming-induced changes therein for future climatic impacts on respiration.Anthropogenic changes in biodiversity and atmospheric temperature significantly influence ecosystem processes. However, little is known about potential interactive effects of plant diversity and warming on essential ecosystem properties, such as soil microbial functions and element cycling. We studied the effects of orthogonal manipulations of plant diversity (one, four, and 16 species) and warming (ambient, +1.5\uffc2\uffb0C, and +3\uffc2\uffb0C) on soil microbial biomass, respiration, growth after nutrient additions, and activities of extracellular enzymes in 2011 and 2012 in the BAC (biodiversity and climate) perennial grassland experiment site at Cedar Creek, Minnesota, USA. Focal enzymes are involved in essential biogeochemical processes of the carbon, nitrogen, and phosphorus cycles. Soil microbial biomass and some enzyme activities involved in the C and N cycle increased significantly with increasing plant diversity in both years. In addition, 16\uffe2\uff80\uff90species mixtures buffered warming induced reductions in topsoil water content. We found no interactive effects of plant diversity and warming on soil microbial biomass and growth rates. However, the activity of several enzymes (1,4\uffe2\uff80\uff90\uffce\uffb2\uffe2\uff80\uff90glucosidase, 1,4\uffe2\uff80\uff90\uffce\uffb2\uffe2\uff80\uff90N\uffe2\uff80\uff90acetylglucosaminidase, phosphatase, peroxidase) depended on interactions between plant diversity and warming with elevated activities of enzymes involved in the C, N, and P cycles at both high plant diversity and high warming levels. Increasing plant diversity consistently decreased microbial biomass\uffe2\uff80\uff90specific enzyme activities and altered soil microbial growth responses to nutrient additions, indicating that plant diversity changed nutrient limitations and/or microbial community composition. In contrast to our expectations, higher plant diversity only buffered temperature effects on soil water content, but not on microbial functions. Temperature effects on some soil enzymes were greatest at high plant diversity. In total, our results suggest that the fundamental temperature ranges of soil microbial communities may be sufficiently broad to buffer their functioning against changes in temperature and that plant diversity may be a dominant control of soil microbial processes in a changing world.

In our assessments, we went beyond the impact on energy requirement and global warming by including impacts on ozone layer and terrestrial acidification and eutrophication. The basic Jatropha biodiesel system consumes eight times less nonrenewable energy than conventional diesel and reduces greenhouse gas emissions by 51%. This result coincides with the lower limit of the range of reduction percentages available in literature for this system and for other liquid biofuels.

This relative simplicity makes these ecosystems particularly vulnerable to perturbations, like global warming, and the Antarctic Peninsula is among the most rapidly warming regions on the planet. However, the consequences of the ongoing warming of Antarctica on microorganisms and the processes they mediate are unknown. Here, using 16S rRNA gene pyrosequencing and qPCR, we report highly consistent responses in microbial communities across disparate sub-Antarctic and Antarctic environments in response to 3 years of experimental field warming (+0.5 to 2 \uffc2\uffb0C). Specifically, we found significant increases in the abundance of fungi and bacteria and in the Alphaproteobacteria-to-Acidobacteria ratio, which could result in an increase in soil respiration. Furthermore, shifts toward generalist bacterial communities following warming weakened the linkage between the bacterial taxonomic and functional richness. GeoChip microarray analyses also revealed significant warming effects on functional communities, specifically in the N-cycling microorganisms. Our results demonstrate that soil microorganisms across a range of sub-Antarctic and Antarctic environments can respond consistently and rapidly to increasing temperatures.

Rising CO(2) may counter that trend by improving plant water-use efficiency. However, it is not clear how important this CO(2)-enhanced water use efficiency might be in offsetting warming-induced desiccation because higher CO(2) also leads to higher plant biomass, and therefore greater transpirational surface. Furthermore, although warming is predicted to favour warm-season, C(4) grasses, rising CO(2) should favour C(3), or cool-season plants. Here we show in a semi-arid grassland that elevated CO(2) can completely reverse the desiccating effects of moderate warming. Although enrichment of air to 600\u2009p.p.m.v. CO(2) increased soil water content (SWC), 1.5/3.0\u2009\u00b0C day/night warming resulted in desiccation, such that combined CO(2) enrichment and warming had no effect on SWC relative to control plots. As predicted, elevated CO(2) favoured C(3) grasses and enhanced stand productivity, whereas warming favoured C(4) grasses. Combined warming and CO(2) enrichment stimulated above-ground growth of C(4) grasses in 2 of 3\u2009years when soil moisture most limited plant productivity.

Here we show that terrestrial carbon uptake (i.e. gross primary production) increased significantly from 1982 to 2011 using a combination of ground-based and remotely sensed land and atmospheric observations. Importantly, we find that the terrestrial carbon uptake increase is not accompanied by a proportional increase in water use (i.e. evapotranspiration) but is largely (about 90%) driven by increased carbon uptake per unit of water use, i.e. water use efficiency. The increased water use efficiency is positively related to rising CO2 concentration and increased canopy leaf area index, and negatively influenced by increased vapour pressure deficits. Our findings suggest that rising atmospheric CO2 concentration has caused a shift in terrestrial water economics of carbon uptake.

The ex situ application of rice straw in uplands, however, may mitigate total global warming potential (GWP) of CH4 and N2O emissions from paddy-upland coexisting systems. To evaluate the efficiency of this practice, two field trials were conducted in rice-rice-fallow and maize-rape cropping systems, respectively. Year-round measurements of CH4 and N2O emissions were conducted to evaluate the system-scaled GWP. The results showed that CH4 accounted for more than 98% of GWP in paddy. Straw removal from paddy decreased 44.7% (302.1\uffe2\uff80\uff89kg ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921) of CH4 emissions and 51.2% (0.31\uffe2\uff80\uff89kg ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921) of N2O emissions, thus decreased 44.8% (7693\uffe2\uff80\uff89kg CO2-eqv ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921) of annual GWP. N2O accounted for almost 100% of GWP in upland.

So, the transfer of straw from paddy to upland could decrease GWP by 7602\uffe2\uff80\uff89kg CO2-eqv ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921. Moreover, straw retention during late rice season contributed to 88.2% of annual GWP increment. It is recommended to transfer early rice straw to upland considering GWP mitigation, nutrient recycling and labor cost.

Yet, despite the importance of soil food webs for energy and nutrient turnover in terrestrial ecosystems, warming effects on these food webs-particularly in combination with other global change drivers-are largely unknown. Here, we present results from two complementary field experiments testing the interactive effects of warming with forest canopy disturbance and drought on energy fluxes in boreal-temperate ecotonal forest soil food webs. The first experiment applied a simultaneous above- and belowground warming treatment (ambient, +1.7\u00b0C, +3.4\u00b0C) to closed canopy and recently clear-cut forest, simulating common forest disturbance6. The second experiment crossed warming with a summer drought treatment (-40% rainfall) in the clear-cut habitats. We show that warming reduces energy fluxes to microbes, while forest canopy disturbance and drought facilitates warming-induced increases in energy flux to higher trophic levels and exacerbates reductions in energy flux to microbes, respectively. Contrary to expectations, we find no change in whole-network resilience to perturbations, but significant losses of ecosystem functioning. Warming thus interacts with forest disturbance and drought, shaping the energetic structure of soil food webs and threatening the provisioning of multiple ecosystem functions in boreal-temperate ecotonal forests.", "keywords": ["0301 basic medicine", "0303 health sciences", "550", "droughts", "610", "forest canopy ecology", "15.

We reveal a threshold precipitation function, determined by the balance between precipitation and ecosystem water demand, which separates temperature-limited and water-limited respiration. Respiration is temperature limited for precipitation above that threshold function, whereas in drier areas water limitation reduces the temperature sensitivity of respiration and its positive feedback to global warming.

Most studies have concentrated on the temperature-effects on plant-insect interactions at individual and population levels, with a particular emphasis on changes in phenology and distribution. Nevertheless, the available evidence from the community level is limited. A 3-year field manipulative experiment was performed to test potential responses of plant and insect communities and plant-insect interactions, to elevated temperature in a meadow steppe. Warming increased the biomass of plant community and forbs and decreased grass biomass, indicating a shift from grass-dominant to grass-forb mixed plant community. Reduced abundance of the insect community under warming, particularly the herbivorous insects, was attributed to lower abundance ofEuchorthippus unicolorand a Cicadellidae species resulting from lower food availability and higher defensive herbivory. Lower herbivore abundance caused lower predator species richness because of reduced prey resources and contributed to an overall decrease in insect species richness. Interestingly, warming enhanced the positive relationship between insect and plant species richness, implying that the strength of the plant-insect interactions was altered by warming. Our results suggest that alterations to plant-insect interactions at a community level under climate warming in grasslands may be more important and complex than previously thought.

In this study, we applied a dual stable isotope approach to investigate the impact of elevated CO2 and elevated temperature on these components of soil CO2 efflux in Douglas\uffe2\uff80\uff90fir terracosms. We measured both soil CO2 efflux rates and the 13C and 18O isotopic compositions of soil CO2 efflux in 12 sun\uffe2\uff80\uff90lit and environmentally controlled terracosms with 4\uffe2\uff80\uff90year\uffe2\uff80\uff90old Douglas fir seedlings and reconstructed forest soils under two CO2 concentrations (ambient and 200 ppmv above ambient) and two air temperature regimes (ambient and 4 \uffc2\uffb0C above ambient). The stable isotope data were used to estimate the relative contributions of different components to the overall soil CO2 efflux. In most cases, litter decomposition was the dominant component of soil CO2 efflux in this system, followed by rhizosphere respiration and soil organic matter oxidation. Both elevated atmospheric CO2 concentration and elevated temperature stimulated rhizosphere respiration and litter decomposition. The oxidation of soil organic matter was stimulated only by increasing temperature. Release of newly fixed carbon as root respiration was the most responsive to elevated CO2, while soil organic matter decomposition was most responsive to increasing temperature. Although some assumptions associated with this new method need to be further validated, application of this dual\uffe2\uff80\uff90isotope approach can provide new insights into the responses of soil carbon dynamics in forest ecosystems to future climate changes.

The wetter site (hereafter \u201cwet site\u201d) was a semi-arid grassy understory of a pi\u00f1on-juniper woodland on the west side of the Kaibab Plateau (Coconino County, Arizona, USA) at an elevation of 2,064 m with approximately 43 cm of precipitation annually (PRISM Climate Group). The drier site (hereafter \u201cdry site\u201d) was a semi-arid grassland adjacent to an alluvial drainage on the east side of the Kaibab Plateau at an elevation of 1710 m with an average of 28 cm of precipitation annually (PRISM Climate Group). The soils at both sites are derived from Kaibab Limestone and the wet site soils are composed of argids while the dry site soils are a mosaic of orthents and calcids. Bouteloua gracilis seed was collected from the two sites using the Seeds of Success protocol (http://www.nps.gov/planTs/sos/protocol/index.htm). Live soil inoculum was collected from the rooting zone of B. gracilis along three 100 m transects established from a random origin (azimuths of 0\u02da, 90\u02da and 270\u02da) at the wet and dry sites. Soil subsamples within each site were pooled together and mixed. We justify homogenizing inoculum from each site because we were interested in seedling responses to average soil biotic conditions across sites, rather than within a single site or extrapolating to a broader geography than our sampling sites (a \u201ctype C\u201d design; Gundale et al. 2017, 2019). Inoculum soil was refrigerated 2 weeks until its use in the experiment. The abundance of different soil organisms in the two inoculum soils was determined using phospholipid fatty acid (PLFA) and neutral lipid fatty acid (NLFA) analysis. Lipids were extracted from 5 g of freeze-dried inoculum soil by vortex mixing in a one-phase mixture of citrate buffer, methanol, and chloroform (0.8:2:1: v/v/v, pH 4.0). The biomass of AM fungi was estimated from the NLFA 16:1 w5: 20:1 w9, and 22:1 w13, biomass of other fungi was estimated from 18:2 w9:12c, and biomass of bacterial groups was estimated signature PLFAs for gram positive and gram negative bacteria (Olsson et al., 1995). This analysis indicated that the soil inoculum from the wet and dry sites had similar abundances of various fungal groups, including AM fungi, and bacteria (Supporting Information Table S1). The community composition of soil fungi in wet and dry inoculum treatments were compared before and after the experiment. Samples of soil were collected and DNA was extracted from 0.5 g of soil using a PowerSoil DNA Extraction Kit (MO BIO Laboratories, Inc., Carlsbad, CA, USA). Genomic DNA was normalized to 2 ng/mL, diluted 10-fold and amplified in triplicate PCR using the universal ITS general eukaryotic primer WANDA and the AM fungal specific primer AML2 for the small subunit (SSU) rRNA gene (Lee et al. 2008; Dumbrell et al. 2011). Purified products were quantified with PicoGreen fluorescence. Indexing PCR was completed using 8 bp dual indexed WANDA and AML2 primers. Indexed PCR products were purified using a 1,1 carboxylated magnetic bead solution, quantified, and combined into a final sample library. The library was purified, concentrated, and quantified using quantitative PCR against Illumina DNA standards on an Illumina MiSeq System (Illumina, Inc., San Diego, CA) running in paired end 2 x 300 bp mode. Forward reads were trimmed to 250 bp to remove low quality tails and demultiplexing was carried out using a minimum quality threshold of q20 and default parameters in QUIIME 1.9.1 (Caporasso et al. 2010) Taxonomy was assigned to sequences using BLAST with 90% similarity and an E-value less than 10-4, against the online MaarjAM database (http,//maarjam.botany.ut.ee; accessed 10 September, 2020, \u014cpik et al. 2010). Taxa that made up less than 1% of relative abundance were labeled as \u2018other\u2019, otherwise species were recorded to the genus level for community comparisons. Many species remained unidentified or classified only to order or family. \u00a0 Experimental design Mesocosms were prepared with all four possible combinations of plant and inoculum origin, two sympatric combinations (inoculum and plants from the wet site, or inoculum and plants from the dry site) and two allopatric combinations (inoculum from the dry site with plants from the wet site, or inoculum from the wet site with plants from the dry site). These treatments were further crossed with two levels of water availability to mimic the severity of water limitation at the two source sites. To generate a frame of reference for the performance of plants without sympatric or allopatric soil organisms under the soil drying regime that most closely resembles their home site, we created two sterile inoculum treatments in which plants from the wet site were grown with sterile soil under a moderate drying regime and plants from the dry site were grown in sterile soil under extreme drying conditions. Each combination of plant ecotype, inoculum origin and drying regime was replicated 9 times, resulting in 72 mesocosms, plus, the two sterile inoculum treatments replicated 9 times for a total of 90 experimental units. \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Mesocosms were constructed from 21 L plastic containers (43 cm x 28 cm x 18 cm) with six 0.3 cm diameter holes drilled into the bottom for drainage. In order to remove the effects of any variation in soil physical and chemical characteristics at the two different sites, we created a sterilized common soil using a 1,1 mixture of soil from the two sites that was steam sterilized at 125\u00b0C for 48 hours. Our experimental design matches type C in Gundale et al. (2017), because unique and variable sub-populations of plant subjects (a random draw of seeds collected from a site) are confronted with one of two soil biota conditions that represent the gamma diversity of each site, and the same background soil condition. This design is preferred when the goal is to detect differences among two or more groups of subjects, and when within-site or regional spatial variation is not a focus (Cahill et al. 2017; Gundale et al. 2017; Gundale et al. 2019). Each mesocosm was filled with approximately 15 liters of sterilized soil and topped with a 1 cm thick band of either live or sterilized (dead) inoculum soil. Bouteloua gracilis seed was sprinkled onto the inoculum soil at a rate of 60 seeds per mesocosm and later thinned to 10 seedlings per mesocosm. Mesocosms were placed in fully randomized spatial locations to account for microclimatic variation within the glasshouse. \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Watering treatments Initially, all mesocosms were watered three times each week for eight weeks and then they were watered twice per week for four weeks before starting the drying treatments. Each watering event brought the mesocosms to field capacity to ensure adequate moisture for plant establishment. Rather than simulate an unrealistically abrupt transition from abundant moisture to dry conditions, we simulated a more gradual transition based on percent of field capacity. These transitions simulate what a plant may experience during the growing seasons as soil moisture diminishes after snowmelt or summer monsoons. Mass at field capacity was estimated by weighing ten randomly selected containers 24 hours after watering. Then, the mass of one randomly selected container was measured every other day, until a soil mass threshold indicated it was time to water again to field capacity. For the moderate drying treatment, we used an initial threshold of 60% of mass at field capacity. For the extreme drying treatment, we used an initial threshold of 40%. After each sequential watering, we decreased both of these threshold percentages by 5%.\u00a0 This both gradually decreased the amount of water available to the plants and increased the length of time between watering events. Eventually, we reached permanent wilting point (approx. -1.5 MPa) in both treatments resulting in at least 90% mortality after 8 months when the experiment was terminated. \u00a0 Plant performance Every two weeks, we measured plant height in all containers and the percentage of plant tissue that was green was monitored to estimate the length of time until plant senescence. Greenness was based on ocular estimates of color. No plants produced inflorescences.\u00a0 At the termination of the experiment, all aboveground biomass was clipped, dried at 60\u00b0C for 24 hours and weighed. Root biomass was sampled by taking four soil cores (5 cm diameter and 18 cm deep). Roots were cleaned, dried and weighed and the weight of roots per volume of core was used to estimate root biomass in the total volume of the mesocosm. \u00a0 AM fungal performance Soil and root materials obtained from destructive harvesting at the end of the experiment were analyzed from all 90 mesocosms.\u00a0 A 10 g subsample of fresh root material was refrigerated until it could be examined for root colonization by fungi. Root samples were cleared with 5% KOH and stained with ink in vinegar (Vierheilig et al., 1998). \u00a0Colonization by AM fungi and other root endophytes was determined using the gridline intersect method at 200 \u00d7 magnification (McGonigle et al., 1990). \u00a0Mycorrhizal root colonization was distinguished as arbuscules, vesicles and hyphae; dark septate endophytes (DSEs) were also quantified.\u00a0 The soil-borne (external) hyphae of AM fungi were extracted from the soil cores after root removal, using the methods of Sylvia (1992), \u00a0and quantified using a gridded eyepiece graticule in an inverse compound microscope at 250 \u00d7 magnification.\u00a0 At points where hyphae intersected gridlines, hyphae were counted, and counts were converted to length of hyphae per gram of soil. Hyphae of AM fungi were distinguished from other fungal hyphae based on their morphology and color.", "keywords": ["2.

Several experimental studies have shown that tundra plants and ecosystems can respond strongly to environmental change, including warming; however, most studies were limited to a single location and were of short duration and based on a variety of experimental designs. In addition, comparisons among studies are difficult because a variety of techniques have been used to achieve experimental warming and different measurements have been used to assess responses. We used metaanalysis on plant community measurements from standardized warming experiments at 11 locations across the tundra biome involved in the International Tundra Experiment. The passive warming treatment increased plant-level air temperature by 1-3\uffc2\uffb0C, which is in the range of predicted and observed warming for tundra regions. Responses were rapid and detected in whole plant communities after only two growing seasons. Overall, warming increased height and cover of deciduous shrubs and graminoids, decreased cover of mosses and lichens, and decreased species diversity and evenness. These results predict that warming will cause a decline in biodiversity across a wide variety of tundra, at least in the short term. They also provide rigorous experimental evidence that recently observed increases in shrub cover in many tundra regions are in response to climate warming. These changes have important implications for processes and interactions within tundra ecosystems and between tundra and the atmosphere.

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. The outstanding tropical land climate characteristic over the past decades is rapid warming, with no significant large-scale precipitation trends. This warming is expected to continue but the effects on tropical vegetation are unknown. El Ni\uffc3\uffb1o-related heat peaks may provide a test bed for a future hotter world. Here we analyse tropical land carbon cycle responses to the 2015/16 El Ni\uffc3\uffb1o heat and drought anomalies using an atmospheric transport inversion. Based on the global atmospheric CO 2 and fossil fuel emission records, we find no obvious signs of anomalously large carbon release compared with earlier El Ni\uffc3\uffb1o events, suggesting resilience of tropical vegetation. We find roughly equal net carbon release anomalies from Amazonia and tropical Africa, approximately 0.5 PgC each, and smaller carbon release anomalies from tropical East Asia and southern Africa. Atmospheric CO anomalies reveal substantial fire carbon release from tropical East Asia peaking in October 2015 while fires contribute only a minor amount to the Amazonian carbon flux anomaly. Anomalously large Amazonian carbon flux release is consistent with downregulation of primary productivity during peak negative near-surface water anomaly (October 2015 to March 2016) as diagnosed by solar-induced fluorescence. Finally, we find an unexpected anomalous positive flux to the atmosphere from tropical Africa early in 2016, coincident with substantial CO release.

Long\uffe2\uff80\uff90term agronomic management impacts on soil organic carbon (SOC) stocks, soil greenhouse gas (GHG) emissions, and global warming potential (GWP) in irrigated systems, however, remain relatively unknown. Here, residue and tillage management effects were quantified by measuring soil nitrous oxide (N2O) and methane (CH4) fluxes and SOC changes (\uffce\uff94SOC) at a long\uffe2\uff80\uff90term, irrigated continuous corn (Zea mays L.) system in eastern Nebraska, United States. Management treatments began in 2002, and measured treatments included no or high stover removal (0 or 6.8\uffc2\uffa0Mg\uffc2\uffa0DM\uffc2\uffa0ha\uffe2\uff88\uff921\uffc2\uffa0yr\uffe2\uff88\uff921, respectively) under no\uffe2\uff80\uff90till (NT) or conventional disk tillage (CT) with full irrigation (n\uffc2\uffa0=\uffc2\uffa04).

Both area\uffe2\uff80\uff90 and yield\uffe2\uff80\uff90scaled soil N2O emissions were greater with stover retention compared to removal and for CT compared to NT, with no interaction between stover and tillage practices. Methane comprised <1% of total emissions, with NT being CH4 neutral and CT a CH4 source. Surface SOC decreased with stover removal and with CT after 14\uffc2\uffa0years of management. When \uffce\uff94SOC, soil GHG emissions, and agronomic energy usage were used to calculate system GWP, all management systems were net GHG sources. Conservation practices (NT, stover retention) each decreased system GWP compared to conventional practices (CT, stover removal), but pairing conservation practices conferred no additional mitigation benefit.

Here we examine the multiyear impact of in situ experimental warming on the microbial food web, vegetation, and their feedbacks with soil chemistry. We provide evidence of both positive and negative impacts of warming on specific microbial functional groups, leading to destabilization of the microbial food web. We observed a strong reduction (70%) in the biomass of top\uffe2\uff80\uff90predators (testate amoebae) in warmed plots. Such a loss caused a shortening of microbial food chains, which in turn stimulated microbial activity, leading to slight increases in levels of nutrients and labile C in water. We further show that warming altered the regulatory role of Sphagnum\uffe2\uff80\uff90polyphenols on microbial community structure with a potential inhibition of top predators. In addition, warming caused a decrease in Sphagnum cover and an increase in vascular plant cover. Using structural equation modelling, we show that changes in the microbial food web affected the relationships between plants, soil water chemistry, and microbial communities. These results suggest that warming will destabilize C and nutrient recycling of peatlands via changes in above\uffe2\uff80\uff90 and belowground linkages, and therefore, the microbial food web associated with mosses will feedback positively to global warming by destabilizing the carbon cycle. This study confirms that microbial food webs thus constitute a key element in the functioning of peatland ecosystems.

In contrast, the trees exposed to both experimental warming and N fertilization did not show increased exudation rates or soil enzyme activity, indicating that the stimulatory effects of experimental warming on root exudation depend on soil fertility. Collectively, our results provide preliminary evidence that an increase in the release of root exudates into the soil may be an important physiological adjustment by which the sustained growth responses of plants to experimental warming may be maintained via enhanced soil microbial activity and soil N transformation.

However, little is known about how plant community structure regulates responses of soil respiration to climate change. Here, we used a 13\uffe2\uff80\uff90year field warming experiment to explore the mechanisms underlying plant community regulation on feedbacks of soil respiration to climate change in a tallgrass prairie in Oklahoma, USA. Infrared heaters were used to elevate temperature about 2\uffc2\uffa0\uffc2\uffb0C since November 1999. Annual clipping was used to mimic hay harvest. Our results showed that experimental warming significantly increased soil respiration approximately from 10% in the first 7\uffc2\uffa0years (2000\uffe2\uff80\uff932006) to 30% in the next 6\uffc2\uffa0years (2007\uffe2\uff80\uff932012). The two\uffe2\uff80\uff90stage warming stimulation of soil respiration was closely related to warming\uffe2\uff80\uff90induced increases in ecosystem production over the years. Moreover, we found that across the 13\uffc2\uffa0years, warming\uffe2\uff80\uff90induced increases in soil respiration were positively affected by the proportion of aboveground net primary production (ANPP) contributed by C3 forbs. Functional composition of the plant community regulated warming\uffe2\uff80\uff90induced increases in soil respiration through the quantity and quality of organic matter inputs to soil and the amount of photosynthetic carbon (C) allocated belowground. Clipping, the interaction of clipping with warming, and warming\uffe2\uff80\uff90induced changes in soil temperature and moisture all had little effect on soil respiration over the years (all P\uffc2\uffa0>\uffc2\uffa00.05). Our results suggest that climate warming may drive an increase in soil respiration through altering composition of plant communities in grassland ecosystems.

We hypothesized that through a shift in the vegetation community from palatable, deciduous dwarf shrubs to unpalatable, evergreen dwarf shrubs, selective herbivory may counteract the increased shrub abundance that is otherwise found in tundra ecosystems, in turn interacting with the responses of ecosystem carbon (C) stocks and CO2 balance to climatic warming. We tested this hypothesis in a 19\uffe2\uff80\uff90year field experiment with factorial treatments of warming and simulated herbivory on the dominant deciduous dwarf shrub Vaccinium\uffc2\uffa0myrtillus. Warming was associated with a significantly increased vegetation abundance, with the strongest effect on deciduous dwarf shrubs, resulting in greater rates of both gross ecosystem production (GEP) and ecosystem respiration (ER) as well as increased C stocks. Simulated herbivory increased the abundance of evergreen dwarf shrubs, most importantly Empetrum nigrum ssp. hermaphroditum, which led to a recent shift in the dominant vegetation from deciduous to evergreen dwarf shrubs. Simulated herbivory caused no effect on GEP and ER or the total ecosystem C stocks, indicating that the vegetation shift counteracted the herbivore\uffe2\uff80\uff90induced C loss from the system. A larger proportion of the total ecosystem C stock was found aboveground, rather than belowground, in plots treated with simulated herbivory. We conclude that by providing a competitive advantage to unpalatable plant species with slow growth rates and long life spans, selective herbivory may promote aboveground C stocks in a warming tundra ecosystem and, through this mechanism, counteract C losses that result from plant biomass consumption.

Volatile terpenoids are the main class of biogenic volatile organic compounds (VOCs) that play crucial roles in atmospheric chemistry and climate. However, the biochemical mechanisms behind the temperature\uffe2\uff80\uff90dependent increase in VOC emissions from subarctic ecosystems are largely unexplored. Using 13CO2\uffe2\uff80\uff90labeling, we studied the origin of VOCs and the carbon (C) allocation under global warming in the soil\uffe2\uff80\uff93plant\uffe2\uff80\uff93atmosphere system of contrasting subarctic heath tundra vegetation communities characterized by dwarf shrubs of the genera Salix or Betula. The projected temperature rise of the subarctic summer by 5\uffc2\uffb0C was realistically simulated in sophisticated climate chambers. VOC emissions strongly depended on the plant species composition of the heath tundra. Warming caused increased VOC emissions and significant changes in the pattern of volatiles toward more reactive hydrocarbons. The 13C was incorporated to varying degrees in different monoterpene and sesquiterpene isomers. We found that de novo monoterpene biosynthesis contributed to 40%\uffe2\uff80\uff9344% (Salix) and 60%\uffe2\uff80\uff9368% (Betula) of total monoterpene emissions under the current climate, and that warming increased the contribution to 50%\uffe2\uff80\uff9358% (Salix) and 87%\uffe2\uff80\uff9395% (Betula). Analyses of above\uffe2\uff80\uff90 and belowground 12/13C showed shifts of C allocation in the plant\uffe2\uff80\uff93soil systems and negative effects of warming on C sequestration by lowering net ecosystem exchange of CO2 and increasing C loss as VOCs. This comprehensive analysis provides the scientific basis for mechanistically understanding the processes controlling terpenoid emissions, required for modeling VOC emissions from terrestrial ecosystems and predicting the future chemistry of the arctic atmosphere. By changing the chemical composition and loads of VOCs into the atmosphere, the current data indicate that global warming in the Arctic may have implications for regional and global climate and for the delicate tundra ecosystems.

Previous studies have focused on the advanced stages of autumnal leaf senescence and reported that climatic warming delayed senescence, despite the fundamental differences among the stages of senescence. However, the timing of onset of leaf coloration (DLCO), the earliest visual sign of senescence, has rarely been studied. Here, we assessed the response of DLCO to temperature.
Location30\uffe2\uff80\uff9375\uffc2\uffb0\uffc2\uffa0N in the Northern Hemisphere.
Time period2000\uffe2\uff80\uff932018.
Major taxa studiedDeciduous vegetation.
MethodsWe retrieved DLCO from high\uffe2\uff80\uff90temporal\uffe2\uff80\uff90resolution satellite data, which were then validated by PhenoCam observations. We investigated the temporal changes in DLCO and the relationship between DLCO and temperature by using satellite and ground observations.
ResultsDLCO was not significantly (p\uffe2\uff80\uff89>\uffe2\uff80\uff89.05) delayed between 2000 and 2018 in 94% of the area. DLCO was positively (p\uffe2\uff80\uff89<\uffe2\uff80\uff89.05) correlated with pre\uffe2\uff80\uff90DLCO mean daily minimum temperature (Tmin) in only 9% of the area, whereas the end of leaf coloration (DLCE) was positively correlated with pre\uffe2\uff80\uff90DLCE mean Tmin over a larger area (34%). Further analyses showed that warming slowed the progress of leaf coloration. Interestingly, DLCO was less responsive to pre\uffe2\uff80\uff90DLCO mean Tmin in areas where daylength was longer across the Northern Hemisphere, particularly for woody vegetation.
Main conclusionsThe rate of progress of coloration is more sensitive to temperature than its start date, resulting in an extension of the duration of leaf senescence under warming. The dependence of DLCO response to temperature on daylength indicates stronger photoperiodic control on initiation of leaf senescence in areas with longer daylength (i.e., shorter nights), possibly because plants respond to the length of uninterrupted darkness rather than daylength. This study indicates that the onset of leaf coloration was not responsive to climate warming and provides observational evidence of photoperiod control of autumnal leaf senescence at biome and continental scales.

Yet, soil carbon models largely ignore these processes and their implications for global responses to warming. Here, we incorporate eco\uffe2\uff80\uff90evolutionary theory into a mechanistic model describing microbial soil carbon decomposition to address the question of whether such processes could have consequential effects on climate carbon feedbacks globally. We assume that a key trait of microbes, their resource allocation to production of exoenzymes (which facilitate decomposition of organic matter)\uffe2\uff80\uff94is optimized to environmental temperatures by natural selection. We find that eco\uffe2\uff80\uff90evolutionary optimization results in microbes allocating more resources to enzyme production under warming. When applied at the global scale, eco\uffe2\uff80\uff90evolutionary optimization enhances the biological realism of soil carbon models and significantly amplifies global soil carbon loss by 2100. Our results highlight the significant potential of microbial eco\uffe2\uff80\uff90evolutionary responses to influence carbon cycle feedbacks to climate change, and motivate an urgent need for more comprehensive data to accurately quantify the adaptive potential of microbiomes in response to climate change.We used a nonintrusive field experiment carried out at six sites \uffe2\uff80\uff93 Wales (UK), Denmark (DK), the Netherlands (NL), Hungary (HU), Sardinia (Italy \uffe2\uff80\uff93 IT), and Catalonia (Spain \uffe2\uff80\uff93 SP) \uffe2\uff80\uff93 along a climatic and latitudinal gradient to examine the response of plant species richness and primary productivity to warming and drought in shrubland ecosystems. The warming treatment raised the plot daily temperature by ca. 1 \uffc2\uffb0C, while the drought treatment led to a reduction in soil moisture at the peak of the growing season that ranged from 26% at the SP site to 82% in the NL site. During the 7 years the experiment lasted (1999\uffe2\uff80\uff932005), we used the pin\uffe2\uff80\uff90point method to measure the species composition of plant communities and plant biomass, litterfall, and shoot growth of the dominant plant species at each site. A significantly lower increase in the number of species pin\uffe2\uff80\uff90pointed per transect was found in the drought plots at the SP site, where the plant community was still in a process of recovering from a forest fire in 1994. No changes in species richness were found at the other sites, which were at a more mature and stable state of succession and, thus less liable to recruitment of new species. The relationship between annual biomass accumulation and temperature of the growing season was positive at the coldest site and negative at the warmest site. The warming treatment tended to increase the aboveground net primary productivity (ANPP) at the northern sites. The relationship between annual biomass accumulation and soil moisture during the growing season was not significant at the wettest sites, but was positive at the driest sites. The drought treatment tended to reduce the ANPP in the NL, HU, IT, and SP sites. The responses to warming were very strongly related to the Gaussen aridity index (stronger responses the lower the aridity), whereas the responses to drought were not. Changes in the annual aboveground biomass accumulation, litterfall, and, thus, the ANPP, mirrored the interannual variation in climate conditions: the most outstanding change was a decrease in biomass accumulation and an increase in litterfall at most sites during the abnormally hot year of 2003. Species richness also tended to decrease in 2003 at all sites except the cold and wet UK site. Species\uffe2\uff80\uff90specific responses to warming were found in shoot growth: at the SP site, Globularia alypum was not affected, while the other dominant species, Erica multiflora, grew 30% more; at the UK site, Calluna vulgaris tended to grow more in the warming plots, while Empetrum nigrum tended to grow less. Drought treatment decreased plant growth in several studied species, although there were some species such as Pinus halepensis at the SP site or C. vulgaris at the UK site that were not affected. The magnitude of responses to warming and drought thus depended greatly on the differences between sites, years, and species and these multiple plant responses may be expected to have consequences at ecosystem and community level. Decreases in biodiversity and the increase in E. multiflora growth at the SP site as a response to warming challenge the assumption that sensitivity to warming may be less well developed at more southerly latitudes; likewise, the fact that one of the studied shrublands presented negative ANPP as a response to the 2003 heat wave also challenges the hypothesis that future climate warming will lead to an enhancement of plant growth and carbon sequestration in temperate ecosystems. Extreme events may thus change the general trend of increased productivity in response to warming in the colder sites.

Aboveground plant biomass also tended to have a lower C\uffe2\uff80\uff83:\uffe2\uff80\uff83N ratio under near\uffe2\uff80\uff90ambient UVB and was differently affected at the two temperatures (marginal UVB \uffc3\uff97 temperature interaction). Leaf decomposition of one dominant sedge species (Carex curta) tended to be faster at near\uffe2\uff80\uff90ambient UVB than at reduced UVB. Leaf decomposition of a codominant species (Carex decidua) was significantly faster at near\uffe2\uff80\uff90ambient UVB; root decomposition of this species tended to be lower at increased temperature and interacted with UVB. We found, for the first time in a field experiment that epigeic earthworm density and biomass was 36% decreased by warming but remained unaffected by UVB radiation. Our results show that present\uffe2\uff80\uff90day solar UVB radiation and modest warming can adversely affect ecosystem functioning and engineers of this fen. However, results on plant biomass production also showed that treatment manipulations of co\uffe2\uff80\uff90occurring global change factors can be overridden by the local climatic situation in a given study year.
