Here, the aim was to investigate the effect of different tillage practices combined with or without irrigation on (i) soil organic carbon (SOC) content, (ii) fungal biomass and their relationships with aggregate size classes in the soil surface layer; further, (iii) the concept of soil particle saturation with SOC was tested to evaluate if a threshold was reached in a 14 year-experiment. Our hypothesis was that long-term irrigation, intensive tillage and their combination, would negatively affect soil aggregation and SOC stabilization. The experiment has started in 2003 on a research farm in Canterbury, New Zealand. The present work focused on two contrasting tillage practices -intensive tillage with 20-25 cm ploughing (IT) and direct drill (DD)- combined with sprinkler-irrigated and non-irrigated (hereafter called Rainfed) conditions in a split-plot experimental design. Soil samples (0-5 cm layer) were analyzed for pore size distribution, specific surface area and microbial biomass. Further, wet sieving was used to isolate large macroaggregates (LM, > 2000 mu m), small macroaggre-gates (SM, 250-2000 mu m), microaggregates (m, 53-250 mu m), particle sized silt + clay fractions (s+c, < 53 mu m) and Fine20 particles (<20 mu m), followed by the analysis of aggregate morphology and SOC quantification in them. Results showed that both DD and Rainfed management increased total SOC content of the bulk soil. Only the LM fraction and the SOC therein (OC-LM) increased significantly in DD compared to IT, while m and s+c fractions and OC-m and OC-s+c did not differ between treatments. Macroaggregate breakdown processes and measured SOC therein had likely not reached steady-state conditions, as suggested by the lack of any SOC dif-ferences in the aggregate size classes < 250 mu m. In contrast, the Fines20:SOC ratio differentiated between soils that had reached (i.e., DD) or not reached (i.e., IT) the saturation threshold. Finally, it was observed that a higher fungal:bacteria (F:B) ratio was generally accompanied by a greater LM fraction and mean weight aggregate diameter, highlighting the importance of fungi in the formation of LM. These results suggested that our hy-pothesis of detrimental effects on soil aggregation and SOC accumulation of both tillage and irrigation was not fully demonstrated yet.

Climate change presents a serious threat to global biodiversity. Loss of pollinators in particular has major implications, with extirpation of these species potentially leading to severe losses in agriculture and, thus, economic losses. In this study, we forecast the effects of climate change on the distribution of hoverflies in Southeast Europe using species distribution modelling and climate change scenarios for two time-periods. For 2041\u20132060, 19 analysed species were predicted to increase their areas of occupancy, with the other 25 losing some of their ranges. For 2061\u20132080, 55% of species were predicted to increase their area of occupancy, while 45% were predicted to experience range decline. In general, range size changes for most species were below 20%, indicating a relatively high resilience of hoverflies to climate change when only environmental variables are considered. Additionally, range-restricted species are not predicted to lose more area proportionally to widespread species. Based on our results, two distributional trends can be established: the predicted gain of species in alpine regions, and future loss of species from lowland areas. Considering that the loss of pollinators from present lowland agricultural areas is predicted and that habitat degradation presents a threat to possible range expansion of hoverflies in the future, developing conservation management strategy for the preservation of these species is crucial. This study represents an important step towards the assessment of the effects of climate changes on hoverflies and can be a valuable asset in creating future conservation plan, thus helping in mitigating potential consequences.", "keywords": ["0106 biological sciences", "LAND-USE", "SELECTING THRESHOLDS", "Global warming", "AQUATIC ECOSYSTEMS", "Conservation", "15.

Grasslands face more frequent and extreme droughts; yet, their responses to increasing drought intensity are poorly understood. Increasing drought intensity likely triggers abrupt shifts (thresholds) in grassland ecosystem functioning which can implicate recovery trajectories.

Here, we determined how drought intensity affects plant productivity, and plant\uffe2\uff80\uff93soil carbon (C) and nitrogen (N) cycling. We exposed model grassland plant communities with contrasting resource acquisition strategies (a fast\uffe2\uff80\uff90 vs a slow\uffe2\uff80\uff90strategy plant community), to a gradient of drought intensity. The drought gradient ranged from well\uffe2\uff80\uff90watered to severely water\uffe2\uff80\uff90limited conditions. We identified thresholds of plant community productivity (above\uffe2\uff80\uff90ground biomass) at peak drought and 2\uffe2\uff80\uff89months after re\uffe2\uff80\uff90wetting, and measured net ecosystem exchange and ecosystem respiration of C\uffc2\uffa0throughout the drought and recovery phases. At peak drought and 1\uffe2\uff80\uff89week after re\uffe2\uff80\uff90wetting, we traced recently acquired C from plants to the soil and into microbial biomass and fatty acids using 13C pulse labelling, and measured plant and soil N.

At peak drought, slow\uffe2\uff80\uff90strategy plant communities were more drought resistant than fast\uffe2\uff80\uff90strategy communities, as the threshold in plant productivity occurred at a higher drought intensity for the slow\uffe2\uff80\uff90 than the fast\uffe2\uff80\uff90strategy community. Shortly after re\uffe2\uff80\uff90wetting, microbial uptake of recent plant\uffe2\uff80\uff90assimilated C increased with increasing past drought intensity, coinciding with an increase in soil N availability and leaf N. Threshold responses to drought intensity at peak drought translated into non\uffe2\uff80\uff90linear recovery responses, with greater compensatory growth in the fast\uffe2\uff80\uff90strategy community. At peak drought, increasing drought intensity reduced C uptake and increased relative C partitioning to leaves and microbial biomass. Upon re\uffe2\uff80\uff90wetting, plant community strategy mediated drought intensity effects on plant and soil C and N dynamics and plant recovery trajectories. The fast\uffe2\uff80\uff90strategy community recovered quickly, with higher leaf N than the slow community, while the slow community increased C allocation to microbial biomass.

Synthesis. Our findings highlight that C and N dynamics in the plant\uffe2\uff80\uff93soil system display non\uffe2\uff80\uff90linear responses to increasing drought intensity both during and after drought, which has implications for plant community recovery trajectories.

Climate change is expected to cause mountain species to shift their ranges to higher elevations. Due to the decreasing amounts of habitats with increasing elevation, such shifts are likely to increase their extinction risk. Heterogeneous mountain topography, however, may reduce this risk by providing microclimatic conditions that can buffer macroclimatic warming or provide nearby refugia. As aspect strongly influences the local microclimate, we here assess whether shifts from warm south\uffe2\uff80\uff90exposed aspects to cool north\uffe2\uff80\uff90exposed aspects in response to climate change can compensate for an upward shift into cooler elevations.

Location

Switzerland, Swiss Alps.

Methods

We built ensemble distribution models using high\uffe2\uff80\uff90resolution climate data for two mountain\uffe2\uff80\uff90dwelling viviparous ectotherms, the Alpine salamander and the Common lizard, and projected them into various future scenarios to gain insights into distributional changes. We further compared elevation and aspect (northness) of current and predicted future locations to analyse preferences and future shifts.

Results

Future ranges were consistently decreasing for the lizard, but for the salamander they were highly variable, depending on the climate scenario and threshold rule. Aspect preferences were elevation\uffe2\uff80\uff90dependent: warmer, south\uffe2\uff80\uff90exposed microclimates were clearly preferred at higher compared to lower elevations. In terms of presence and future locations, we observed both elevational upward shifts and northward shifts in aspect. Under future conditions, the shift to cooler north\uffe2\uff80\uff90exposed aspects was particularly pronounced at already warmer lower elevations.

Main conclusions

For our study species, shifts in aspect and elevation are complementary strategies to mitigate climatic warming in the complex mountain topography. This complements the long\uffe2\uff80\uff90standing view of elevational upward shift being their only option to move into areas with suitable future climate. High\uffe2\uff80\uff90resolution climate data are critical in heterogeneous environments to identify microrefugia and thereby improving future impact assessments of climate change.

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 A Soil Monitoring Law to improve soil health across all land uses has been proposed by the European Commission. As forests soils have different chemical and physical properties as well as biogeochemical dynamics compared to agricultural land, they also face different challenges in maintaining and restoring soil health. Examples are soil acidification, eutrophication by atmospheric deposition, responses to climate change, and loss of biodiversity. Therefore, we propose forest soil specific health descriptors and thresholds based on experience and knowledge from existing long-term monitoring programs.

Although the trait concept is increasingly used in research, quantitative relations that can support in determining ecological tipping points and serve as a basis for environmental standards are lacking. This study determines changes in trait abundance along a gradient of flow velocity, turbidity and elevation, and develops trait\u2013response curves, which facilitate the identification of ecological tipping points. Aquatic macroinvertebrates and abiotic conditions were determined at 88 different locations in the streams of the Guayas basin. After trait information collection, a set of trait diversity metrics were calculated. Negative binomial regression and linear regression were applied to relate the abundance of each trait and trait diversity metrics, respectively, to flow velocity, turbidity and elevation. Tipping points for each environmental variable in relation to traits were identified using the segmented regression method. The abundance of most traits increased with increasing velocity, while they decreased with increasing turbidity. The negative binomial regression models revealed that from a flow velocity higher than 0.5 m/s, a substantial increase in abundance occurs for several traits, and this is even more substantially noticed at values higher than 1 m/s. Furthermore, significant tipping points were also identified for elevation, wherein an abrupt decline in trait richness was observed below 22 m a.s.l., implying the need to focus water management in these altitudinal regions. Turbidity is potentially caused by erosion; thus, measures that can reduce or limit erosion within the basin should be implemented. Our findings suggest that measures mitigating the issues related to turbidity and flow velocity may lead to better aquatic ecosystem functioning. This quantitative information related to flow velocity might serve as a good basis to determine ecological flow requirements and illustrates the major impacts that hydropower dams can have in fast-running river systems. These quantitative relations between invertebrate traits and environmental conditions, as well as related tipping points, provide a basis to determine critical targets for aquatic ecosystem management, achieve improved ecosystem functioning and warrant trait diversity.

Abstract. Earlier studies have demonstrated that soil texture and geochemistry strongly affect soil organic carbon (SOC) content. However, those findings primarily rely on data from temperate regions with soil mineralogy, weathering status and climatic conditions that generally differ from tropical and sub-tropical regions. We investigated soil properties and climate variables influencing SOC concentrations across sub-Saharan Africa. A total of 1,601 samples were analyzed, collected from two depths (0\u201320\u2009cm and 20\u201350\u2009cm) at 45 sentinel sites from 17 countries as part of the Africa Soil Information Service (AfSIS) project. The dataset spans climatic conditions from arid to humid and includes soils with a wide range of pHH20 values, weathering status, soil texture, exchangeable cations, extractable metals and a variety of important land cover types. The most important SOC predictors were identified by linear mixed effects models, regression trees and random forest models. Our results indicate that SOC is primarily controlled by aridity index (PET/MAP), exchangeable calcium (Caex) and oxalate-extractable aluminum (Alox); this was found across both depth intervals.

Climate change presents a serious threat to global biodiversity. Loss of pollinators in particular has major implications, with extirpation of these species potentially leading to severe losses in agriculture and, thus, economic losses. In this study, we forecast the effects of climate change on the distribution of hoverflies in Southeast Europe using species distribution modelling and climate change scenarios for two time-periods. For 2041\u20132060, 19 analysed species were predicted to increase their areas of occupancy, with the other 25 losing some of their ranges. For 2061\u20132080, 55% of species were predicted to increase their area of occupancy, while 45% were predicted to experience range decline. In general, range size changes for most species were below 20%, indicating a relatively high resilience of hoverflies to climate change when only environmental variables are considered. Additionally, range-restricted species are not predicted to lose more area proportionally to widespread species. Based on our results, two distributional trends can be established: the predicted gain of species in alpine regions, and future loss of species from lowland areas. Considering that the loss of pollinators from present lowland agricultural areas is predicted and that habitat degradation presents a threat to possible range expansion of hoverflies in the future, developing conservation management strategy for the preservation of these species is crucial.

Here, the aim was to investigate the effect of different tillage practices combined with or without irrigation on (i) soil organic carbon (SOC) content, (ii) fungal biomass and their relationships with aggregate size classes in the soil surface layer; further, (iii) the concept of soil particle saturation with SOC was tested to evaluate if a threshold was reached in a 14 year-experiment. Our hypothesis was that long-term irrigation, intensive tillage and their combination, would negatively affect soil aggregation and SOC stabilization. The experiment has started in 2003 on a research farm in Canterbury, New Zealand. The present work focused on two contrasting tillage practices -intensive tillage with 20-25 cm ploughing (IT) and direct drill (DD)- combined with sprinkler-irrigated and non-irrigated (hereafter called Rainfed) conditions in a split-plot experimental design. Soil samples (0-5 cm layer) were analyzed for pore size distribution, specific surface area and microbial biomass. Further, wet sieving was used to isolate large macroaggregates (LM, > 2000 mu m), small macroaggre-gates (SM, 250-2000 mu m), microaggregates (m, 53-250 mu m), particle sized silt + clay fractions (s+c, < 53 mu m) and Fine20 particles (<20 mu m), followed by the analysis of aggregate morphology and SOC quantification in them. Results showed that both DD and Rainfed management increased total SOC content of the bulk soil. Only the LM fraction and the SOC therein (OC-LM) increased significantly in DD compared to IT, while m and s+c fractions and OC-m and OC-s+c did not differ between treatments. Macroaggregate breakdown processes and measured SOC therein had likely not reached steady-state conditions, as suggested by the lack of any SOC dif-ferences in the aggregate size classes < 250 mu m. In contrast, the Fines20:SOC ratio differentiated between soils that had reached (i.e., DD) or not reached (i.e., IT) the saturation threshold. Finally, it was observed that a higher fungal:bacteria (F:B) ratio was generally accompanied by a greater LM fraction and mean weight aggregate diameter, highlighting the importance of fungi in the formation of LM. These results suggested that our hy-pothesis of detrimental effects on soil aggregation and SOC accumulation of both tillage and irrigation was not fully demonstrated yet.

In Europe, rural landscapes and forests have been subjected to intensive anthropogenic transformations and uses since Antiquity. Since the early 20th century, many traditionally managed forests and mountain pastures were transformed into intensive forestry plantations. Hence, it is important to assess the effects of forest plantations on soil health. The European Soil Monitoring Law (SML) proposes the establishment of soil units for monitoring soil health and soil degradation processes using time\uffe2\uff80\uff90series of several indicators: SOC:clay for soil organic carbon (SOC) loss, pH for acidification and bulk density for compaction, among others. Thresholds that may be local must be defined for these different indicators. We propose an approach in which: (1) we delineate soil units applying unsupervised classification to a set of environmental covariates, proxies of the soil\uffe2\uff80\uff90forming factors (pedogenon mapping) and (2) use semi\uffe2\uff80\uff90natural native forests (i.e., secondary forests of native species with lesser human interventions compared to past decades) as references for setting unit\uffe2\uff80\uff90specific thresholds for soil indicators (reference approach) and (3) assessing and mapping the condition of forest plantations (intensively managed forests). We apply this approach to the Basque Country using soil data from the forest monitoring network Basonet. When considering the threshold suggested by the SML for SOC:clay (<\uffe2\uff80\uff891/13), 61% of plots at 0\uffe2\uff80\uff9320\uffe2\uff80\uff89cm layer and 90% at 20\uffe2\uff80\uff9340\uffe2\uff80\uff89cm layer of plantations were in poor condition (unhealthy), while 37% of plots at 0\uffe2\uff80\uff9320\uffe2\uff80\uff89cm and 79% at 20\uffe2\uff80\uff9340\uffe2\uff80\uff89cm of semi\uffe2\uff80\uff90natural forests would be considered unhealthy. When considering semi\uffe2\uff80\uff90natural forest as references the proportion of plantation plots in poor condition for SOC:clay ranged between 14%\uffe2\uff80\uff9350% depending on the percentile used to set thresholds (5th and 25th percentiles). Forest plantations had lower soil pH compared to semi\uffe2\uff80\uff90natural forests, with 15%\uffe2\uff80\uff9360% of plantation plots with pH lower than the unit\uffe2\uff80\uff90specific thresholds (poor condition). Only 3% of topsoils and 2% of subsoils under plantations were considered unhealthy with a fixed pH threshold of 4.2. All plantation plots were in good condition (healthy) in terms of bulk density with the EU criteria, but 9.6% of semi\uffe2\uff80\uff90natural plots had greater bulk density than the suggested thresholds. Our approach demonstrates the need of considering the context of soil\uffe2\uff80\uff90forming factors when identifying thresholds for soil health indicators.

Abstract. Earlier studies have demonstrated that soil texture and geochemistry strongly affect soil organic carbon (SOC) content. However, those findings primarily rely on data from temperate regions with soil mineralogy, weathering status and climatic conditions that generally differ from tropical and sub-tropical regions. We investigated soil properties and climate variables influencing SOC concentrations across sub-Saharan Africa. A total of 1,601 samples were analyzed, collected from two depths (0\u201320\u2009cm and 20\u201350\u2009cm) at 45 sentinel sites from 17 countries as part of the Africa Soil Information Service (AfSIS) project. The dataset spans climatic conditions from arid to humid and includes soils with a wide range of pHH20 values, weathering status, soil texture, exchangeable cations, extractable metals and a variety of important land cover types. The most important SOC predictors were identified by linear mixed effects models, regression trees and random forest models. Our results indicate that SOC is primarily controlled by aridity index (PET/MAP), exchangeable calcium (Caex) and oxalate-extractable aluminum (Alox); this was found across both depth intervals. Oxalate-extractable iron (Feox) emerged as the most important predictor for both depth intervals in the regression tree and random forest analyses. However, its influence on SOC concentrations was strong only below Feox concentrations of 0.25\u2009wt\u2009%. This suggests that Feox can act as a pedogenic threshold \u2013 even on a continental scale. Across model-ling approaches, clay and fine silt content (

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.

Grasslands face more frequent and extreme droughts; yet, their responses to increasing drought intensity are poorly understood. Increasing drought intensity likely triggers abrupt shifts (thresholds) in grassland ecosystem functioning which can implicate recovery trajectories.

Here, we determined how drought intensity affects plant productivity, and plant\uffe2\uff80\uff93soil carbon (C) and nitrogen (N) cycling. We exposed model grassland plant communities with contrasting resource acquisition strategies (a fast\uffe2\uff80\uff90 vs a slow\uffe2\uff80\uff90strategy plant community), to a gradient of drought intensity. The drought gradient ranged from well\uffe2\uff80\uff90watered to severely water\uffe2\uff80\uff90limited conditions. We identified thresholds of plant community productivity (above\uffe2\uff80\uff90ground biomass) at peak drought and 2\uffe2\uff80\uff89months after re\uffe2\uff80\uff90wetting, and measured net ecosystem exchange and ecosystem respiration of C\uffc2\uffa0throughout the drought and recovery phases. At peak drought and 1\uffe2\uff80\uff89week after re\uffe2\uff80\uff90wetting, we traced recently acquired C from plants to the soil and into microbial biomass and fatty acids using 13C pulse labelling, and measured plant and soil N.

At peak drought, slow\uffe2\uff80\uff90strategy plant communities were more drought resistant than fast\uffe2\uff80\uff90strategy communities, as the threshold in plant productivity occurred at a higher drought intensity for the slow\uffe2\uff80\uff90 than the fast\uffe2\uff80\uff90strategy community. Shortly after re\uffe2\uff80\uff90wetting, microbial uptake of recent plant\uffe2\uff80\uff90assimilated C increased with increasing past drought intensity, coinciding with an increase in soil N availability and leaf N. Threshold responses to drought intensity at peak drought translated into non\uffe2\uff80\uff90linear recovery responses, with greater compensatory growth in the fast\uffe2\uff80\uff90strategy community. At peak drought, increasing drought intensity reduced C uptake and increased relative C partitioning to leaves and microbial biomass. Upon re\uffe2\uff80\uff90wetting, plant community strategy mediated drought intensity effects on plant and soil C and N dynamics and plant recovery trajectories. The fast\uffe2\uff80\uff90strategy community recovered quickly, with higher leaf N than the slow community, while the slow community increased C allocation to microbial biomass.

Synthesis. Our findings highlight that C and N dynamics in the plant\uffe2\uff80\uff93soil system display non\uffe2\uff80\uff90linear responses to increasing drought intensity both during and after drought, which has implications for plant community recovery trajectories.
