Consistent responses of soil microbial communities to elevated nutrient inputs in grasslands across the globe
The results suggest that elevated N and P inputs lead to predictable shifts in the taxonomic and functional traits of soil microbial communities, including increases in the relative abundances of faster-growing, copiotrophic bacterial taxa, with these shifts likely to impact belowground ecosystems worldwide.

Productivity Is a Poor Predictor of Plant Species Richness
Standardized sampling from many sites worldwide was used to address an important ecological problem. For more than 30 years, the relationship between net primary productivity and species richness hasExpand
Plant diversity predicts beta but not alpha diversity of soil microbes across grasslands worldwide.
Across a global range of temperate grasslands, plant diversity can predict patterns in the composition of soil microbial communities, but not patterns in alpha diversity. Expand
Integrative modelling reveals mechanisms linking productivity and plant species richness
It is found that an integrative model has substantially higher explanatory power than traditional bivariate analyses and several surprising findings that conflict with classical models are revealed. Expand
Herbivores and nutrients control grassland plant diversity via light limitation
Testing the hypothesis that herbaceous plant species losses caused by eutrophication may be offset by increased light availability due to herbivory demonstrates that nutrients and herbivores can serve as counteracting forces to control local plant diversity through light limitation, independent of site productivity, soil nitrogen, herbivore type and climate.

Revisiting the Holy Grail: using plant functional traits to understand ecological processes
The utility of trait‐based approaches in ecology will benefit from efforts that demonstrate how these traits and indices influence organismal, community, and ecosystem processes across vegetation types, which may be achieved through meta‐analysis and enhancement of trait databases. Expand
Grassland productivity limited by multiple nutrients
It is suggested that multiple-nutrient constraints must be considered when assessing the ecosystem-scale consequences of nutrient enrichment, and significant variations in the type and degree of nutrient limitation are pointed to. Expand
Woody species diversity influences productivity and soil nutrient availability in tropical plantations
The conversion of natural forest with highly productive, low-diversity gymnosperm-dominated plantations was found to be associated with lower soil nutrient availability and lower soil pH, suggesting that monoculture plantations can be used to successfully restore some functions, but that the level to which such functions can be restored will depend upon the species chosen and site conditions.

Eutrophication weakens stabilizing effects of diversity in natural grasslands
The results demonstrate separate and synergistic effects of diversity and eutrophication on stability, emphasizing the need to understand how drivers of global change interactively affect the reliable provisioning of ecosystem services in real-world systems. Expand
Rapid, Long-Distance Dispersal by Pumice Rafting
A significant recent pumice rafting and long-distance dispersal event that occurred across the southwest Pacific following the 2006 explosive eruption of Home Reef Volcano in Tonga is reported on, discovering more than 80 species and a substantial biomass underwent a >5000 km journey in 7–8 months.
