Long-term decline in grassland productivity driven by increasing dryness
Increasing aridity and drought severity forecast for many land areas could reduce the land carbon (C) sink. However, with limited long-term direct measures, it is difficult to distinguish direct drying effects from counter effects of CO2 enrichment and nitrogen (N) deposition. Here, we document a >50% decline in production of a native C3 grassland over four decades and assign the forcing and ti...

متن کاملDiversity and productivity in a long-term grassland experiment.
Plant diversity and niche complementarity had progressively stronger effects on ecosystem functioning during a 7-year experiment, with 16-species plots attaining 2.7 times greater biomass than monocultures. Diversity effects were neither transients nor explained solely by a few productive or unviable species. Rather, many higher-diversity plots outperformed the best monoculture. These results h...
متن کاملIncreasing service productivity by characteristics-driven recommendations for action
Service productivity is becoming increasingly important, since organisations face a growing competitive environment. With this article we propose an ontology linking several service characteristics with strategies to increase productivity. These strategies were identified in the course of an extensive review of academic literature. The ontology can be applied as a practical guide for decision m...
متن کاملRoot depth distribution and the diversity–productivity relationship in a long-term grassland experiment
The relationship between plant diversity and productivity in grasslands could depend, partly, on how diversity affects vertical distributions of root biomass in soil; yet, no prior study has evaluated the links among diversity, root depth distributions, and productivity in a long-term experiment. We used data from a 12-year experiment to ask how plant species richness and composition influenced...
