Abstract Global change, especially land‐use intensification, affects human well‐being by impacting the delivery of multiple ecosystem services (multifunctionality). However, whether biodiversity loss is a major component global change effects on multifunctionality in real‐world ecosystems, as experimental ones, remains unclear. Therefore, we assessed biodiversity, functional composition and 14 150 agricultural grasslands differing intensity. We also introduce five measures which were...
Background Soil bacteria are important drivers for nearly all biogeochemical cycles in terrestrial ecosystems and participate most nutrient transformations soil. In contrast to the importance of soil ecosystem functioning, we understand little how different management types affect bacterial community composition. Methodology/Principal Findings We used pyrosequencing-based analysis V2-V3 16S rRNA gene region identify changes diversity structure nine forest grassland soils from Schwäbische Alb...
Abstract Estimates of carbon leaching losses from different land use systems are few and their contribution to the net ecosystem balance is uncertain. We investigated dissolved organic (DOC), inorganic (DIC), methane (CH 4 ), at forests, grasslands, croplands across Europe. Biogenic contributions DIC were estimated by means its δ 13 C signature. Leaching biogenic was 8.3±4.9 g m −2 yr −1 for 24.1±7.2 14.6±4.8 croplands. DOC equalled 3.5±1.3 5.3±2.0 4.1±1.3 The average flux total 19.4±4.0 ....
Abstract Soil bacteria provide a large range of ecosystem services such as nutrient cycling. Despite their important role in soil systems, compositional and functional responses bacterial communities to different land use management regimes are not fully understood. Here, we assessed 150 forest grassland soils derived from three German regions by pyrotag sequencing 16S rRNA genes. Land type (forest grassland) edaphic properties strongly affected community structure function, whereas regime...
The diversity of bacteria in soil is enormous, and bacterial communities can vary greatly structure. Here, we employed a pyrosequencing-based analysis the V2-V3 16S rRNA gene region to characterize overall horizon-specific (A B horizons) community compositions nine grassland soils, which covered three different land use types. entire data set comprised 752,838 sequences, 600,544 could be classified below domain level. average number sequences per horizon was 41,824. dominant taxonomic groups...
Abstract. Precise determination of changes in organic carbon (OC) stocks is prerequisite to understand the role soils global cycling and verify due management. A large dataset was collected form base repeated soil inventories at 12 CarboEurope sites under different climate land-use, with types. Concentration OC, bulk density (BD), fine earth fraction were determined 60 cm depth 100 sampling points per site. We investigated (1) time needed detect assuming future re-sampling cores; (2)...
Abstract. Conceptual models suggest that stability of organic carbon (OC) in soil depends on the source plant litter, occlusion within aggregates, incorporation organo-mineral complexes, and location profile. Density fractionation is a useful tool to study relevance OC stabilization aggregates association with minerals, but it has rarely been applied full profiles. We aim determine factors shaping depth profiles physically unprotected mineral associated test their for across range European...
Significance Ecosystem services derive from ecosystem functions and rely on complex interactions among a diversity of organisms. By understanding the relationships between biodiversity, functions, humans receive nature, we can anticipate how changes in land use will affect ecosystems human wellbeing. We show that increasing land-use intensity homogenizes synergies three organizational levels ecosystem, namely, services. Increasing keystone components, which are important for functioning...
Trade-offs and synergies in the supply of forest ecosystem services are common but drivers these relationships poorly understood. To guide management that seeks to promote multiple services, we investigated between 12 stand-level attributes, including structure, composition, heterogeneity plant diversity, plus 4 environmental factors, proxies for 14 150 temperate plots. Our results show attributes best predictors most also good several trade-offs services. Environmental factors play an...
Abstract The active bacterial rhizobiomes and root exudate profiles of phytometers six plant species growing in central European temperate grassland communities were investigated three regions located up to 700 km apart, across diverse edaphic conditions along a strong land use gradient. recruitment process from bulk soil was identified as the major direct driver composition rhizosphere communities. Unexpectedly, effect properties, particularly texture, water content, type, strongly...
Abstract Land-use intensification is a major driver of biodiversity loss. However, understanding how different components land use drive loss requires the investigation multiple trophic levels across spatial scales. Using data from 150 agricultural grasslands in central Europe, we assess influence local- and landscape-level on more than 4,000 above- belowground taxa, spanning 20 groups. Plot-level land-use intensity strongly negatively associated with aboveground groups, but positively or...
Abstract Organismal functional strategies form a continuum from slow- to fast-growing organisms, in response common drivers such as resource availability and disturbance. However, whether there is synchronisation of these at the entire community level unclear. Here, we combine trait data for >2800 above- belowground taxa 14 trophic guilds spanning disturbance gradient German grasslands. The results indicate that most consistently respond through both direct trophically mediated effects,...

Fine root decomposition contributes significantly to element cycling in terrestrial ecosystems. However, studies on rates and the factors that potentially influence them are fewer than those leaf litter decomposition. To study effects of region land use intensity fine decomposition, we established a large scale three German regions with different climate regimes soil properties. Methods In 150 forest grassland sites deployed litterbags (100 μm mesh size) standardized consisting roots from...
Very few principles have been unraveled that explain the relationship between soil properties and biota across large spatial scales different land-use types. Here, we seek these general relationships using data from 52 differently managed grassland forest soils in three study regions spanning a latitudinal gradient Germany. We hypothesize that, after extraction of variation is explained by location type, still significant proportions abundance diversity biota. If predictors organisms were...
Species diversity promotes the delivery of multiple ecosystem functions (multifunctionality). However, relative functional importance rare and common species in driving biodiversity–multifunctionality relationship remains unknown. We studied between (according to their local abundances across nine different trophic groups), multifunctionality indices derived from 14 on 150 grasslands a land-use intensity (LUI) gradient. The above- below-ground had opposite effects, with above-ground being...
Climate change in Arctic ecosystems fosters permafrost thaw and makes massive amounts of ancient soil organic carbon (OC) available to microbial breakdown. However, fractions the matter (OM) may be protected from rapid decomposition by their association with minerals. Little is known about effects mineral-organic associations (MOA) on accessibility OM soils it not clear which factors control its temperature sensitivity. In order investigate if how OC turnover affected mineral controls, heavy...
The complex interactions between trees and soil microbes in forests as well their inherent seasonal spatial variations are poorly understood. In this study, we analyzed the effects of major European tree species (Fagus sylvatica L. Picea abies (L.) Karst) on bacterial fungal communities. Mineral samples were collected from different depths (0-10 cm, 10-20 cm) at horizontal distances beech or spruce trunks (0.5, 1.5, 2.5, 3.5 m) early summer autumn. We assessed composition communities based...
Distance decay, the general reduction in similarity of community composition with increasing geographical distance, is known as predictor spatial variation and distribution patterns organisms. However, changes fungal communities along environmental gradients are little known. Here we show that distance decays soil-inhabiting root-associated assemblages differ, identify explanatory variables. High-throughput sequencing analysis beech-dominated forests at three study sites across Germany shows...
