Significance Accurate prediction of community responses to global change drivers (GCDs) is critical given the effects biodiversity on ecosystem services. There consensus that human activities are driving species extinctions at scale, but debate remains over whether GCDs systematically altering local communities worldwide. Across 105 experiments included 400 experimental manipulations, we found evidence for a lagged response herbaceous plant caused by shifts in identities and relative...
Abstract Redesigning agrosystems to include more ecological regulations can help feed a growing human population, preserve soils for future productivity, limit dependency on synthetic fertilizers, and reduce agriculture contribution global changes such as eutrophication warming. However, guidelines redesigning cropping systems from natural make them sustainable remain limited. Synthetizing the knowledge biogeochemical cycles in ecosystems, we outline four that synchronize supply of soluble...
Climate change projections anticipate increased frequency and intensity of drought stress, but grassland responses to severe droughts their potential recover are poorly understood. In many grasslands, high land-use has enhanced productivity promoted resource-acquisitive species at the expense resource-conservative ones. Such changes in plant functional composition could affect resistance recovery after ecosystems with consequences for feed resilience environmental stewardship. a 12-site...
Abstract Interactions between biodiversity loss and climate change present significant challenges for research, policy management of ecosystems. Evidence suggests that high species diversity tends to increase plant community stability under interannual fluctuations mild dry wet events, but the overall pattern diversity–stability relationships extremes is unclear. We comprehensively review results from observational experimental studies assess importance effects ecosystem function extremes....
Abstract Climate change predictions suggest that summer droughts will become more intense and recurrent in Europe. While drought‐induced reductions grassland primary productivity are well documented, the drivers behind drought resistance (the capacity to withstand change) recovery for of function) above‐ below‐ground biomass remain poorly understood. Across eight grasslands differing plant community (CP), we investigated effects on soil microbial variables, nutrient content, nitrogen (N)...
Abstract Emissions of the trace gas nitrous oxide ( N 2 O ) play an important role for greenhouse effect and stratospheric ozone depletion, but impacts climate change on fluxes underlying microbial drivers remain unclear. The aim this study was to determine effects sustained field associated enzymatic activities, population abundance community diversity in extensively managed, upland grassland. We recorded fluxes, nitrification denitrification, size involved these processes structure nitrite...
Abstract Questions How does above‐ground grassland biomass production respond to change in multiple climate drivers over a 4‐yr period? Can climate‐induced patterns of response be explained by shifts plant community structure? Does sustained affect the relationships between abundance functional groups, community‐scale leaf traits and production? Location Perennial French Massif Central. Methods Monoliths extracted from study were exposed simulated corresponding air temperature, atmospheric...
Abstract Biodiversity can buffer ecosystem functioning against extreme climatic events, but few experiments have explicitly tested this. Here, we present the first multisite biodiversity × drought manipulation experiment to examine resistance and recovery at five temperate Mediterranean grassland sites. Aboveground biomass production declined by 30% due experimental (standardised local extremity rainfall exclusion for 72–98 consecutive days). Species richness did not affect promoted...
Summary Past work on tropical rain forest tree seedlings has been dominated by contrasts between strongly light‐demanding and shade‐tolerant species. We examined patterns of growth mortality among in response to light, investigated the morphological physiological correlates high seedling survival rates across Seedlings 15 species from Australian lowland were grown for up 1 year neutral‐density shadehouses at three light levels (10%, 0.8% 0.2% full daylight). All showed negligible 10%...
Ecosystem functions are threatened by both recurrent droughts and declines in biodiversity at a global scale, but the drought dependency of diversity-productivity relationships remains poorly understood. Here, we use two-phase mesocosm experiment with simulated model oldfield communities (360 experimental mesocosms/plant communities) to examine drought-induced changes soil microbial along plant species richness gradient assess interactions between past (soil legacies) subsequent on...
Abstract Questions How does the spatial configuration of sampling units influence recorded plant species richness values at small scales? What are consequences these findings for methodology and rarefaction analyses? Location Six semi‐natural grasslands in Western Eurasia (France, Germany, Bulgaria, Hungary, Italy, Turkey). Methods In each site we established six blocks 40 cm × 280 cm, subdivided into 5 micro‐quadrats, on which vascular presence with rooted (all sites) shoot (four method....
Abstract Increasing evidence suggests that agricultural intensification is a threat to many groups of soil biota, but how the impacts land-use intensity on organisms translate into changes in comprehensive interaction networks remains unclear. Here for first time, we use environmental DNA examine total multi-trophic diversity and food web structure temperate agroecosystems along gradient intensity. We tested response patterns key properties webs sixteen fields ranging from arable crops...
Summary Previous studies on tropical rainforest seedlings have demonstrated low physiological plasticity in shade‐tolerant species response to light, but little is known about the morphological of such species. We examined traits 10 tree grown four combinations high and light (10 0·8% full daylight, respectively). Plasticity each trait was quantified using coefficients variation. Plant varied their plasticity, could broadly be ranked as follows: stem form > crown root leaf biomass...
ABSTRACT Grasslands provide a wide range of different ecosystem services (ES) that are crucial for human well‐being. This increases the interest in understanding drivers grassland ES to maintain and enhance supply future generations. However, many do currently not have market value show trade‐offs, is, antagonistic relationships, strengthened by management intensification. For example, high forage production is key farm income, but conflicts with cultural biodiversity conservation. Balancing...
Temperature anomalies, such as heatwaves and cold spells, are becoming increasingly common, posing significant challenges to ecosystem functioning carbon sequestration. While temperature anomalies have been shown influence broad-scale flux patterns, their fine-scale effects, particularly in conjunction with agricultural management, remain poorly understood. This study investigates the impact of air (Tair) on CO₂ fluxes an upland mesic grassland under two grazing management regimes:...
<title>Abstract</title> Aim Belowground ecosystems in grasslands are influenced by the aboveground plant community, but interactions between local environmental conditions and type remain unclear. To address this, soil micro-food webs were examined grassland monocultures of three functional groups (grasses, legumes, forbs) different Mediterranean regions. Methods At sites Spain, France Slovenia, properties structure function microbial nematode assemblages autumn spring consecutive seasons....
