Belowground Biomass Response to Nutrient Enrichment Depends on Light Limitation Across Globally Distributed Grasslands
Anthropogenic activities are increasing nutrient inputs to ecosystems worldwide, with consequences for global carbon and nutrient cycles. Recent meta-analyses show that aboveground primary production is often ...

Leaf nutrients, not specific leaf area, are consistent indicators of elevated nutrient inputs
Leaf traits are frequently measured in ecology to provide a ‘common currency’ for predicting how anthropogenic pressures impact ecosystem function. Here, we test whether leaf traits consistently respond to exp...

Local loss and spatial homogenization of plant diversity reduce ecosystem multifunctionality
Biodiversity is declining in many local communities while also becoming increasingly homogenized across space. Experiments show that local plant species loss reduces ecosystem functioning and services, but the...

Nitrogen deposition promotes phosphorus uptake of plants in a semi-arid temperate grassland
Nitrogen (N) deposition greatly influences ecosystem processes through the alteration of plant nutrition; however, there is limited understanding about the effects of phosphorus (P) inputs, especially within t...

Open AccessDivergent Effects of Nitrogen Addition on Soil Respiration in a Semiarid Grassland
Nitrogen (N) deposition has been steadily increasing for decades, with consequences for soil respiration. However, we have a limited understanding of how soil respiration responds to N availability. Here, we i...

Article
Addition of multiple limiting resources reduces grassland diversity
Analysis of multi-year nutrient enrichment experiments carried out on 45 global grassland sites show that an addition of an increasing number of nutrients leads to a reduction in plant species diversity, and c...

Drivers of Variation in Aboveground Net Primary Productivity and Plant Community Composition Differ Across a Broad Precipitation Gradient
Aboveground net primary production (ANPP) is a key integrator of C uptake and energy flow in many terrestrial ecosystems. As such, ecologists have long sought to understand the factors driving variation in thi...

Article
Soil nutrient additions increase invertebrate herbivore abundances, but not herbivory, across three grassland systems
Resource availability may influence invertebrate communities, with important consequences for ecosystem function, such as biomass production. We assessed: (1) the effects of experimental soil nutrient addition...

Open AccessPlant species’ origin predicts dominance and response to nutrient enrichment and herbivores in global grasslands
Exotic species dominate many communities; however the functional significance of species’ biogeographic origin remains highly contentious. This debate is fuelled in part by the lack of globally replicated, sys...

Article
Global environmental change and the nature of aboveground net primary productivity responses: insights from long-term experiments
Many global change drivers chronically alter resource availability in terrestrial ecosystems. Such resource alterations are known to affect aboveground net primary production (ANPP) in the short term; however,...

Differential sensitivity to regional-scale drought in six central US grasslands
Terrestrial ecosystems often vary dramatically in their responses to drought, but the reasons for this are unclear. With climate change forecasts for more frequent and extensive drought in the future, a more c...

Article
Functional trait expression of grassland species shift with short- and long-term nutrient additions
Humans are altering nutrient availability worldwide, likely affecting plant trait expression, with consequences for community composition and ecosystem function. Here, we examined the responses of plant specie...

Article
Herbivores and nutrients control grassland plant diversity via light limitation
Experimental data collected from 40 grasslands on 6 continents show that nutrients and herbivores can serve as counteracting forces to control local plant diversity; nutrient addition reduces local diversity t...

Eutrophication weakens stabilizing effects of diversity in natural grasslands
Experimental eutrophication weakens the stabilizing effects of plant diversity on the productivity of natural grasslands.

Phytoplankton composition modifies predator-driven life history evolution in Daphnia
Organisms experience competing selective pressures, which can obscure the mechanisms driving evolution. Daphnia ambigua is found in lakes where a predator, the alewife (Alosa pseudoharengus) eithe...

Open AccessStrong feeding preference of an exotic generalist herbivore for an exotic forb: a case of invasional antagonism
Many hypotheses dealing with the success of invasive plant species concern plant–herbivore interactions. The invasional meltdown and enemy inversion hypotheses suggest that non-native herbivores may indirectly...
