Soil pH varies by several units among ecosystems. While soil pH is known to be a key driver of plant species composition, we still have a poor understanding of how it affects carbon cycling processes. For instance, soil pH, or its associated chemistry in terms of base cations and organic acids, may affect decomposition rates of dead matter directly, by controlling decomposer composition and activity, and indirectly, by controlling the traits of the plant species and thereby the afterlife effects of those traits on litter decomposition. Leaf and litter pH may play a role in this control. Based on the very limited empirical data available, we hypothesized that variation in species traits including leaf (litter) pH, within and between ecosystems contrasting in soil pH, would have stronger effects on leaf litter decomposition rates than variation in soil chemistry would. 2. We tested this hypothesis by carrying out a \u2018common garden\u2019 litterbed experiment in subtropical SW China, in which leaf litters of the 30 predominant plant species from mid-successional forest on acidic sandstone (soil pH around 4.0) and calcareous soil (pH around 7.5) respectively, were incubated and their decomposition rates measured over two harvests in fourteen months, both in soil plus litter matrix from their \u2018home\u2019 forest and in those from the \u201caway\u201d forest. 3. We found that leaf (litter) trait variation among species and plant functional types, headed by species\u2019 dry matter content but also including tissue pH, was the strongest driver of variation in leaf litter decomposition rates. Surprisingly however, while these effects of interspecific trait variation were very strong among species from the same site, there was no overall difference in litter decomposability between the species from the acidic versus calcareous site. Equally surprising was that this strong difference in pH of soil substrate plus litter matrix from an acidic sandstone site versus a calcareous karst site did not directly affect leaf litter decomposition rates across a given species set. 4. This first attempt to disentangle the multiple potential direct and indirect ways in which soil and leaf (litter) acidity might be related to litter decomposition rates, has important implications for our understanding of soil-plant feedbacks. Based on our forest-based study, we predict that soil-plant feedbacks via acidity are unlikely to be strong in ecosystems with wide-ranging species in terms of their leaf functional traits, including leaf pH.", "keywords": ["litter pH", "Leaf traits", "soil-plant feedbacks", "soil acidity", "Soil chemistry", "calcareous substrate", "15.

In order to establish suitability of forest ecosystems for long\uffe2\uff80\uff90term storage of C, it is necessary to characterize the effects of predicted increased atmospheric CO2 levels on the pools and fluxes of C within these systems. Since most C held in terrestrial ecosystems is in the soil, we assessed the influence of Free Air Carbon Enrichment (FACE) treatment on the total soil C content (Ctotal) and incorporation of litter derived C (Cnew) into soil organic matter (SOM) in a fast growing poplar plantation. Cnew was estimated by the C3/C4 stable isotope method. Ctotal contents increased under control and FACE respectively by 12 and 3%, i.e., 484 and 107 gC/m2, while 704 and 926 gC/m2 of new carbon was sequestered under control and FACE during the experiment. We conclude that FACE suppressed the increase of Ctotal and simultaneously increased Cnew. We hypothesize that these opposite effects may be caused by a priming effect of the newly incorporated litter, where priming effect is defined as the stimulation of SOM decomposition caused by the addition of labile substrates.

Arctic cyclones, as a prevalent feature in the coupled dynamics of the Arctic climate system, have large impacts on the atmospheric transport of heat and moisture and deformation and drifting of sea ice. Previous studies based on historical and future simulations with climate models suggest that Arctic cyclogenesis is affected by the Arctic amplification of global warming, for instance, a growing land-sea thermal contrast. We thus hypothesize that biogeophysical feedbacks (BF) over the land, here mainly referring to the albedo-induced warming in spring and evaporative cooling in summer, may have the potential to significantly change cyclone activity in the Arctic. Based on a regional Earth system model (RCA-GUESS) which couples a dynamic vegetation model and a regional atmospheric model and an algorithm of cyclone detection and tracking, this study assesses for the first time the impacts of BF on the characteristics of Arctic cyclones under three IPCC Representative Concentration Pathways scenarios (i.e. RCP2.6, RCP4.5 and RCP8.5). Our analysis focuses on the spring- and summer time periods, since previous studies showed BF are the most pronounced in these seasons. We find that BF induced by changes in surface heat fluxes lead to changes in land-sea thermal contrast and atmospheric stability. This, in turn, noticeably changes the atmospheric baroclinicity and, thus, leads to a change of cyclone activity in the Arctic, in particular to the increase of cyclone frequency over the Arctic Ocean in spring. This study highlights the importance of accounting for BF in the prediction of Arctic cyclones and the role of circulation in the Arctic regional Earth system.

Increasing primary productivity in tropical forests over recent decades has been attributed to CO2 fertilization, and greater biomass in tropical forests could represent a substantial sink for carbon in the future. However, the carbon sequestration capacity of tropical forest soils is uncertain and feedbacks between increased plant productivity and soil carbon dynamics remain unexplored. Here, we show that experimentally increasing litterfall in a lowland tropical forest enhanced carbon release from the soil. Using a large-scale litter manipulation experiment combined with carbon isotope measurements, we found that the efflux of CO2 derived from soil organic carbon was significantly increased by litter addition. Furthermore, this effect was sustained over several years. We predict that a future increase in litterfall of 30% with an increase in atmospheric CO2 concentrations of 150 ppm could release about 0.6 t C ha-1 yr-1 from the soil, partially offsetting predicted net gains in carbon storage.

In contrast, SOC in the subsoil (30\uffe2\uff80\uff93100\uffe2\uff80\uff89cm) initially increased with N addition but decreased over time. The model selection analysis revealed that experimental duration and vegetation type are among the most important predictors across a wide range of climatic, environmental, and edaphic variables. The contrasting responses of SOC to N addition indicate the importance of considering deep soil layers, particularly for long\uffe2\uff80\uff90term continuous N deposition. Finally, the lack of depth\uffe2\uff80\uff90dependent SOC responses to N addition in experimental and modeling frameworks has likely resulted in the overestimation of changes in SOC storage under enhanced N deposition.

Rising atmospheric carbon dioxide (CO2) could alter the carbon (C) and nitrogen (N) content of ecosystems, yet the magnitude of these effects are not well known. We examined C and N budgets of a subtropical woodland after 11\uffc2\uffa0yr of exposure to elevated CO2.

We used open\uffe2\uff80\uff90top chambers to manipulate CO2 during regrowth after fire, and measured C, N and tracer 15N in ecosystem components throughout the experiment.

Elevated CO2 increased plant C and tended to increase plant N but did not significantly increase whole\uffe2\uff80\uff90system C or N. Elevated CO2 increased soil microbial activity and labile soil C, but more slowly cycling soil C pools tended to decline. Recovery of a long\uffe2\uff80\uff90term 15N tracer indicated that CO2 exposure increased N losses and altered N distribution, with no effect on N inputs.

Increased plant C accrual was accompanied by higher soil microbial activity and increased C losses from soil, yielding no statistically detectable effect of elevated CO2 on net ecosystem C uptake. These findings challenge the treatment of terrestrial ecosystems responses to elevated CO2 in current biogeochemical models, where the effect of elevated CO2 on ecosystem C balance is described as enhanced photosynthesis and plant growth with decomposition as a first\uffe2\uff80\uff90order response.

There is strong evidence for a phylogenetic signal in the degree to which species share co\uffe2\uff80\uff90evolved biotic partners and in the outcomes of biotic interactions. This implies there should be a phylogenetic signal in the outcome of feedbacks between plants and the soil microbiota they cultivate. However, attempts to identify a phylogenetic signal in plant\uffe2\uff80\uff93soil feedbacks have produced mixed results.

Here we clarify how phylogenetic signals could arise in plant\uffe2\uff80\uff93soil feedbacks and use a recent compilation of data from feedback experiments to identify: whether there is a phylogenetic signal in the outcome of plant\uffe2\uff80\uff93soil feedbacks; and whether any signal arises through directional or divergent changes in feedback outcomes with evolutionary time.

We find strong evidence for a divergent phylogenetic signal in feedback outcomes. Distantly related plant species show more divergent responses to each other\uffe2\uff80\uff99s soil microbiota compared with closely related plant species. The pattern of divergence implies occasional co\uffe2\uff80\uff90evolutionary shifts in how plants interact with soil microbiota, with strongly contrasting feedback responses among some plant lineages.

Our results highlight that it is difficult to predict feedback outcomes from phylogeny alone, other than to say that more closely related species tend to have more similar responses.

Increasing aridity due to climate change is expected to affect multiple ecosystem structural and functional attributes in global drylands, which cover \uffe2\uff88\uffbc45% of the terrestrial globe. Berdugo et al. show that increasing aridity promotes thresholds on the structure and functioning of drylands (see the Perspective by Hirota and Oliveira). Their database includes 20 variables summarizing multiple aspects and levels of ecological organization. They found evidence for a series of abrupt ecological events occurring sequentially in three phases, culminating with a shift to low-cover ecosystems that are nutrient- and species-poor at high aridity values. They estimate that more than 20% of land surface will cross at least one of the thresholds by 2100, which can potentially lead to widespread land degradation and desertification worldwide.

Science , this issue p. 787 ; see also p. 739 Accurately estimating evapotranspiration (ET) at large spatial scales is essential to our understanding of land-atmosphere coupling and the surface balance of water and energy. Comparisons between remote sensing-based ET models are difficult due to diversity in model formulation, parametrization and data requirements. The constituent components of ET have been shown to deviate substantially among models as well as between models and field estimates. This study analyses the sensitivity of three global ET remote sensing models in an attempt to isolate the error associated with forcing uncertainty and reveal the underlying variables driving the model components. We examine the transpiration, soil evaporation, interception and total ET estimates of the Penman-Monteith model from the Moderate Resolution Imaging Spectroradiometer (PM-MOD), the Priestley-Taylor Jet Propulsion Laboratory model (PT-JPL) and the Global Land Evaporation Amsterdam Model (GLEAM) at 42 sites where ET components have been measured using field techniques. We analyse the sensitivity of the models based on the uncertainty of the input variables and as a function of the raw value of the variables themselves. We find that, at 10% added uncertainty levels, the total ET estimates from PT-JPL, PM-MOD and GLEAM are most sensitive to Normalized Difference Vegetation Index (NDVI) (%RMSD = 100.0), relative humidity (%RMSD = 122.3) and net radiation (%RMSD = 7.49), respectively. Consistently, systemic bias introduced by forcing uncertainty in the component estimates is mitigated when components are aggregated to a total ET estimate. These results suggest that slight changes to forcing may result in outsized variation in ET partitioning and relatively smaller changes to the total ET estimates. Our results help to explain why model estimates of total ET perform relatively well despite large inter-model divergence in the individual ET component estimates.

Abstract. Improving the skill of Earth system models (ESMs) in representing climate\uffe2\uff80\uff93vegetation interactions is crucial to enhance our predictions of future climate and ecosystem functioning. Therefore, ESMs need to correctly simulate the impact of climate on vegetation, but likewise feedbacks of vegetation on climate must be adequately represented. However, model predictions at large spatial scales remain subjected to large uncertainties, mostly due to the lack of observational patterns to benchmark them. Here, the bidirectional nature of climate\uffe2\uff80\uff93vegetation interactions is explored across multiple temporal scales by adopting a spectral Granger causality framework that allows identification of potentially co-dependent variables. Results based on global and multi-decadal records of remotely sensed leaf area index (LAI) and observed atmospheric data show that the climate control on vegetation variability increases with longer temporal scales, being higher at inter-annual than multi-month scales. Globally, precipitation is the most dominant driver of vegetation at monthly scales, particularly in (semi-)arid regions. The seasonal LAI variability in energy-driven latitudes is mainly controlled by radiation, while air temperature controls vegetation growth and decay in high northern latitudes at inter-annual scales. These observational results are used as a benchmark to evaluate four ESM simulations from the Coupled Model Intercomparison Project Phase\uffc2\uffa05 (CMIP5). Findings indicate a tendency of ESMs to over-represent the climate control on LAI dynamics and a particular overestimation of the dominance of precipitation in arid and semi-arid regions at inter-annual scales. Analogously, CMIP5 models overestimate the control of air temperature on seasonal vegetation variability, especially in forested regions. Overall, climate impacts on LAI are found to be stronger than the feedbacks of LAI on climate in both observations and models; in other words, local climate variability leaves a larger imprint on temporal LAI dynamics than vice versa. Note however that while vegetation reacts directly to its local climate conditions, the spatially collocated character of the analysis does not allow for the identification of remote feedbacks, which might result in an underestimation of the biophysical effects of vegetation on climate. Nonetheless, the widespread effect of LAI variability on radiation, as observed over the northern latitudes due to albedo changes, is overestimated by the CMIP5 models. Overall, our experiments emphasise the potential of benchmarking the representation of particular interactions in online ESMs using causal statistics in combination with observational data, as opposed to the more conventional evaluation of the magnitude and dynamics of individual variables.

There is strong evidence for a phylogenetic signal in the degree to which species share co\uffe2\uff80\uff90evolved biotic partners and in the outcomes of biotic interactions. This implies there should be a phylogenetic signal in the outcome of feedbacks between plants and the soil microbiota they cultivate. However, attempts to identify a phylogenetic signal in plant\uffe2\uff80\uff93soil feedbacks have produced mixed results.

Here we clarify how phylogenetic signals could arise in plant\uffe2\uff80\uff93soil feedbacks and use a recent compilation of data from feedback experiments to identify: whether there is a phylogenetic signal in the outcome of plant\uffe2\uff80\uff93soil feedbacks; and whether any signal arises through directional or divergent changes in feedback outcomes with evolutionary time.

We find strong evidence for a divergent phylogenetic signal in feedback outcomes. Distantly related plant species show more divergent responses to each other\uffe2\uff80\uff99s soil microbiota compared with closely related plant species. The pattern of divergence implies occasional co\uffe2\uff80\uff90evolutionary shifts in how plants interact with soil microbiota, with strongly contrasting feedback responses among some plant lineages.

Our results highlight that it is difficult to predict feedback outcomes from phylogeny alone, other than to say that more closely related species tend to have more similar responses.

Increasing aridity due to climate change is expected to affect multiple ecosystem structural and functional attributes in global drylands, which cover \uffe2\uff88\uffbc45% of the terrestrial globe. Berdugo et al. show that increasing aridity promotes thresholds on the structure and functioning of drylands (see the Perspective by Hirota and Oliveira). Their database includes 20 variables summarizing multiple aspects and levels of ecological organization. They found evidence for a series of abrupt ecological events occurring sequentially in three phases, culminating with a shift to low-cover ecosystems that are nutrient- and species-poor at high aridity values. They estimate that more than 20% of land surface will cross at least one of the thresholds by 2100, which can potentially lead to widespread land degradation and desertification worldwide.

Science , this issue p. 787 ; see also p. 739 Emerging evidence points out that the responses of soil organic carbon (SOC) to nitrogen (N) addition differ along the soil profile, highlighting the importance of synthesizing results from different soil layers. Here, using a global meta\uffe2\uff80\uff90analysis, we found that N addition significantly enhanced topsoil (0\uffe2\uff80\uff9330\uffe2\uff80\uff89cm) SOC by 3.7% (\uffc2\uffb11.4%) in forests and grasslands. In contrast, SOC in the subsoil (30\uffe2\uff80\uff93100\uffe2\uff80\uff89cm) initially increased with N addition but decreased over time. The model selection analysis revealed that experimental duration and vegetation type are among the most important predictors across a wide range of climatic, environmental, and edaphic variables. The contrasting responses of SOC to N addition indicate the importance of considering deep soil layers, particularly for long\uffe2\uff80\uff90term continuous N deposition. Finally, the lack of depth\uffe2\uff80\uff90dependent SOC responses to N addition in experimental and modeling frameworks has likely resulted in the overestimation of changes in SOC storage under enhanced N deposition.50\u2009years of soil warming. Warming of >50\u2009years drove the ecosystem to a new steady state possessing a distinct biotic composition and reduced species richness, biomass and soil organic matter. However, the warmed state was preceded by an overreaction to warming, which was related to organism physiology and was evident after 5-8\u2009years. Ignoring this overreaction yielded errors of >100% for 83\u2009variables when predicting their responses to a realistic warming scenario of 1\u2009\u00b0C over 50\u2009years, although some, including soil carbon content, remained stable after 5-8\u2009years. This study challenges long-term ecosystem predictions made from short-term observations, and provides a framework for characterization of ecosystem responses to sustained climate change.", "keywords": ["0301 basic medicine", "570", "Environmental management", "INCREASES", "Ecosystem ecology", "Climate Change", "Evolutionary biology", "TERM", "630", "Article", "Carbon Cycle", "Soil", "03 medical and health sciences", "SDG 13 - Climate Action", "106026 Ecosystem research", "Life Below Water", "Ecosystem", "106022 Mikrobiologie", "0303 health sciences", "Ecology", "Climate-change ecology", "SHIFTS", "Biological Sciences", "15.
