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...
In the past two decades, a large number of studies have investigated relationship between biodiversity and ecosystem functioning, most which focussed on limited set variables. The Jena Experiment was up in 2002 to investigate effects plant diversity element cycling trophic interactions, using multi-disciplinary approach. Here, we review results 15 years research Experiment, focussing manipulating species richness functional richness. With more than 85,000 measures taken from plots, has...
ABSTRACT In soil, Acidobacteria constitute on average 20% of all bacteria, are highly diverse, and physiologically active in situ . However, their individual functions interactions with higher taxa soil still unknown. Here, potential effects land use, properties, plant diversity, nanofauna acidobacterial community composition were studied by cultivation-independent methods grassland forest soils from three different regions Germany. The analysis 16S rRNA gene clone libraries representing...
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...
Plant diversity drives changes in the soil microbial community which may result alterations ecosystem functions. However, governing factors between composition of communities and plant are not well understood. We investigated impact (plant species richness functional group richness) identity on biomass structure experimental grassland ecosystems. Total were determined by phospholipid fatty acid (PLFA) analysis. The gradient covered 1, 2, 4, 8, 16 60 3 4 groups (grasses, legumes, small herbs...
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...
The natural world is increasingly defined by change. Within the next 100 years, rising atmospheric CO2 concentrations will continue to increase frequency and magnitude of extreme weather events. Simultaneously, human activities are reducing global biodiversity, with current extinction rates at ~1,000 × what they were before domination Earth's ecosystems. co–occurrence these trends may be particular concern, as greater biological diversity could help ecosystems resist change during large...
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...
Abstract Human‐caused declines in biodiversity have stimulated intensive research on the consequences of loss for ecosystem services and policy initiatives to preserve functioning ecosystems. Short‐term experiments documented positive effects plant species richness many functions, longer‐term studies indicate, some that can become stronger over time. Theoretically, a effect strengthen time by an increasing performance high‐diversity communities, decreasing low‐diversity or combination both...
Abstract Experiments showed that biodiversity increases grassland productivity and nutrient exploitation, potentially reducing fertiliser needs. Enhancing could improve P-use efficiency of grasslands, which is beneficial given rock-derived P fertilisers are expected to become scarce in the future. Here, we show a experiment more diverse plant communities were able exploit resources completely than less ones. In agricultural grasslands studied, management effects either overruled or modified...
ABSTRACT International commitments advocate large‐scale forest restoration as a nature‐based solution to climate change mitigation through carbon (C) sequestration. Mounting evidence suggests that mixed compared monospecific planted forests may sequester more C, exhibit lower susceptibility extremes and offer broader range of ecosystem services. However, experimental studies comprehensively examining the control tree diversity on multiple C stocks fluxes above‐ belowground are lacking. To...
Increasing plant species richness decreases soil NO 3 - concentrations in experimental mixtures, but the role of particular functional groups has remained unclear. Most analyses have focused on times year or were restricted to . We tested whether affect size plant-available N pools (KCl-extractable , dissolved inorganic and organic [DON] total [TDN] solution) aboveground biomass. Furthermore, we assessed seasonal variations effects groups. The grassland site had 86 plots with different...
The diversity–stability hypothesis states that current losses of biodiversity can impair the ability an ecosystem to dampen effect environmental perturbations on its functioning. Using data from a long-term and comprehensive experiment, we quantified temporal stability 42 variables characterizing twelve ecological functions in managed grassland plots varying plant species richness. We demonstrate diversity increases i) across trophic levels (producer, consumer), ii) at both system...
